Essential workers such as teachers, health workers and community safety staff play a vital role in ensuring our society works well. Yet soaring housing costs in cities like Sydney, Melbourne and Brisbane are squeezing essential workers out of the communities they serve.

The issue is reaching crisis point across Australia. Anglicare Australia yesterday released a special edition of its Rental Affordability Snapshot focused on essential workers in full-time work. Housing costs under 30% of household income are considered affordable. In a survey of 45,115 rental listings, it found:

  • 3.7% were affordable for a teacher
  • 2.2% were affordable for an ambulance worker
  • 1.5% were affordable for an aged care worker
  • 1.4% were affordable for a nurse
  • 0.9% were affordable for an early childhood educator
  • 0.8% were affordable for a hospitality worker.

This trend is creating unsustainable patterns of urban sprawl and long commutes. It erodes workers’ quality of life. It also undermines public service delivery by making it harder to recruit and retain these workers in high-cost areas.

International experience, particularly in the UK where I have advised on similar policies, shows there are solutions to this crisis. These global lessons fall into four categories.

1. Define essential worker housing

Essential worker housing typically targets front-line public sector workers on low to middle incomes. Yet eligibility should extend to support roles, such as ambulance drivers, porters and medical receptionists, who play a vital part in enabling front-line services. They too struggle to find affordable housing near their workplaces.

Conditions of eligibility should also include a cap on household earnings.

The UK experience highlights the importance of providing both rental and ownership options. To keep key worker housing affordable and accessible over time, both types need to be priced appropriately.

Australian cities could adopt similar approaches, by requiring housing developers and community housing providers to allocate affordable housing for essential workers. Prices would be below market rates for both rentals and home ownership for the long term, and not revert to market rates. This ensures stability for public service workers.

2. Financial innovations focused on long-term affordability

Innovative financial models, such as shared equity schemes, have succeeded in the UK. These allow workers to gradually buy into their homes, creating long-term stability.

Shared equity involves the government or another investor covering some of the cost of buying the home in exchange for an equivalent share in the property. Australia could explore similar schemes to provide immediate relief while ensuring sustained affordability for future essential workers.

This approach could build on the Commonwealth’s proposed Help to Buy scheme, currently before the Senate, and existing state and territory shared equity programs. These may need refinement to better serve essential workers by, for example, adjusting income thresholds and eligibility criteria to ensure they qualify. These schemes also need to expand to cover all urban areas where housing affordability is most strained.

3. Leverage planning systems

Countries like the UK have leveraged their planning systems to deliver affordable housing for key workers. In England, planning authorities use mechanisms such as Section 106 agreements to ensure a portion of new developments is reserved for key worker housing as a condition of planning approval.

Australian states could adapt this model, setting targets within existing planning frameworks. For example, they could use Voluntary Planning Agreements to prioritise essential worker housing.

Yet essential worker housing should not displace housing for other people in urgent need. They include people who are homeless, low-income families, people with disabilities, the elderly, those at risk of domestic violence, veterans and youth leaving foster care.

4. Use public land for housing development

The use of surplus public land for essential worker housing has proven successful in several cities, including London, Amsterdam and San Francisco.

Earmarking land owned by the public sector, such as hospital or education sites, is a strategic way to deliver affordable housing near key public sector employers. It also allows staff to travel to work nearby using sustainable transport instead of cars.

Affordable housing has profound benefits

Without action, essential workers are likely to be forced into lower-quality, high-cost housing, shared accommodation, or long commutes from more affordable areas. Over time, these patterns of job-housing imbalances and urban sprawl are unsustainable. These issues are the focus of my current research, particularly in Western Sydney.

The New South Wales government has set up a parliamentary select committee to inquire into options for essential worker housing. It’s bringing much-needed attention to the housing crisis affecting key public sector roles.

Tackling these issues through targeted housing solutions has many benefits. It can help create more sustainable communities, reduce recruitment and retention difficulties for employers and ease the strain on infrastructure and services.

The key takeaway from the UK and other countries is the importance of long-term, sustainable solutions that do not shift the focus away from those most in need of housing. Australia has the opportunity to strike this balance. We need to ensure essential workers can afford to live near their workplaces while not sidelining everyone else in need of affordable housing.

Death of an idol: response to Liam Payne’s death highlights the power of childhood and music

Source: The Conversation (Au and NZ) – By Liz Giuffre, Senior Lecturer in Communication, University of Technology Sydney

Former One Direction band member and solo artist Liam Payne has been found dead outside a hotel in Buenos Aires, media reports have confirmed. Payne was just 31 years old – a loved friend and father.

Alongside his former One Direction band mates Niall Horan, Harry Styles, Louis Tomlinson and Zayn Malik, Payne had a huge influence on popular culture in his home country of the United Kingdom and internationally.

The group formed in 2010 on the British talent show X Factor and stayed together for about five years before officially splitting in 2016. Throughout this time, Payne remained a valuable member of the band and a clear talent in his own right.

Although each member auditioned seperately, they were eventually hand-picked by Simon Cowell to form a group.

After the split (and a brief hiatus from music-making), Payne continued to release music periodically as both a songwriter and collaborator. He most recently released the single Teardrops in March, ahead of an anticipated second solo album.

News of Payne’s death has led to an outpouring of tributes. Like many young people thrust into stardom seemingly overnight, his life wasn’t without controversy. But the response to his death by fans and industry colleagues alike is proof of the impact he had.

The making of a pop supergroup

While One Direction may have not been together for as long as other globally successful acts, their influence far exceeded bands that have been together for decades. They released five studio records – and broke many more, including six Guinness World Records. And even though they didn’t make it to their 10th anniversary together, they had still sold some 70 million records by 2020.

In the years since the split, fans continued to gather, listen and celebrate – with the most recent anniversary (14 years) seeing fan-led events held in Australia and the rest of the world.

It’s easy to dismiss pop music and its influence, especially in the face of what feel like increasingly dire global circumstances. But pop, like many other forms of entertainment, provides a practical way for people to gain momentary pleasure and comfort.

It also provides connection with others – and relief from politics and other daily pressures. For example, one of One Direction’s biggest hits, That’s What Makes You Beautiful, sought to empower young people who might otherwise be overwhelmed by negative messaging.

Within a year of their debut, the group was met with massive crowds of fans almost everywhere they want.

One Direction has been compared to The Beatles in terms of their influence on young people – and female and queer fans in particular.

The impact on fans when their idol dies

The loss of life, especially a young person’s life, is always a tragedy.

For some young fans, this might be the first person they “know” who has died. While it may not be the same as losing a family member or close friend, the feeling of loss is significant. Young fans will need support. And in 2024, many will find this support through social platforms and online forums.

I still remember the impact the deaths of stars such as Kurt Cobain and Jeff Buckley had on people like me who were teenagers in the 1990s. These were artists I admired and listened to – and whose art I relied on during times of pleasure and pain.

A similar pang was felt when artists such as George Michael, Aretha Franklin and David Bowie died, albeit later in my life and theirs.

The experience of losing a music idol is in many ways a universal one. People whose art we attach to our own life experiences become inseparable from our lives. And when they die, it can feel like those experiences are over too.

After news of Payne’s death broke, hundreds of fans took to the streets of Palermo in Buenos Aires, where Payne had been visiting. They held a vigil, cried and consoled one another in front of the Casa Sur hotel where Payne had been staying.

One fan, 25-year-old Yamila Zacarias, probably spoke for many when she said:

He meant a lot to me because the band came into my life at this time when you’re trying to be a part of something, and being a One Direction fan became that something for me.

Lifelong fandom and memories

There’s a stereotype of “fans” as hordes of screaming girls, which can really take away from the depth of fandom.

Anyone at any stage of life can be a fan of just about anything. And the best thing about fandom is that it can, and often does, allow lots of different types of people an outlet for connection throughout their lives.

Many fans have left comments on old music videos.

The death of US actress Betty White in 2021, as sad as it was, brought people across generations and walks of life together. And not just those who knew her personally, but those who had connected with each other through their love of her work. It reminded me of my own family, including my Nan and Dad, now gone, and the laughs we’d share as we watched her.

As more details and tributes to Payne’s life and death emerge, the fans will have each other to lean on. If you yourself know someone who is a fan of Payne or One Direction, even reaching out to just acknowledge that person’s grief and experience is important. It says to them, “what you love is valid, and so are you”.

A man lived to old age without knowing he may have had 3 penises

Source: The Conversation (Au and NZ) – By Amanda Meyer, Senior Lecturer, Anatomy and Pathology, James Cook University

Life science/Shutterstock

Do you really know what you look like on the inside? Most people do not, and usually it takes surgery or medical imaging to take a look while we are still alive.

A case study was published last week where researchers made the rare finding of a man with “triphallia”. Most people would say the man had three penises. But anatomists, like myself, who teach health professionals about the structure of the human body, prefer the term penes (plural of penis).

This finding emerged from the dissection of the body of a 78-year-old man who had donated his body to science. It is a case that has left many anatomists scratching their heads, and ignited discussions about typical human anatomy and anatomical variation.

I too have an extra organ – an extra spleen – plus other anatomical variations regarding two muscles. It is highly likely you might also have anatomical variations, and not necessarily know.

Back to this case

According to the latest study, only one penis was externally visible. But when his body was dissected, there were two extra, smaller penises inside the scrotum.

The main penis was 77mm long and 24mm wide, with the smaller ones about half the size. However, the images provided in the study don’t seem to match the written descriptions in all places. So the study does need clarification.

Intriguingly, researchers identified a single urethra – the hollow tube from the bladder that allows urine (and sperm from the testes) to leave the body. This urethra travelled from the bladder through part of one of the smaller penises and along the length of the main penis, leaving out the third penis entirely.

Was there a misunderstanding in identifying these anatomical structures? Could the second penis simply be a misidentified part of the main one? Is this actually a case of diphallia – two penises? In either case, the man’s anatomy was different to what you’d typically see in anatomy textbooks.

The study suggests all three penises contained erectile tissue capable of engorgement. But it remains unclear whether they worked independently or together. Unfortunately, the authors did not confirm structures by examining them under the microscope, or report tracing the nerves or blood vessels, to shed more light.

There was an earlier case in a baby

A separate case of someone with three penises, which was documented in 2020, involved a three-month-old infant.

In this instance, the main penis was in its typical position, but you could see the extra ones on the perineum (between the anus and the scrotum in males).

Neither of the extra penises had a urethra, making them incapable of functioning typically. Ultimately, these non-functional penises were safely removed.

Such cases are rare, with only these two examples reported in medical databases.

So how does this happen? The answer may lie in how embryos develop.

Early in development

The penis begins to develop early in the first trimester of a 40-week pregnancy, a time when a woman may not know she’s pregnant.

During this critical period, the embryo may be exposed to various influences. These include toxins passed through the bloodstream if the mother falls ill, takes certain drugs while pregnant or is exposed to certain chemicals. There are also genetic factors that shape how organs develop.

By the fifth week of pregnancy, cells migrate to the midline of the embryo, where they help form the precursor to the penis.

Problems in this migratory process, abnormalities in a developmental gene (called “sonic hedgehog”), or fluctuations in testosterone levels or receptors during early fetal development, could potentially lead to the formation of additional penises.

Humans are varied

While the appearance of triphallia may be startling, these rare cases highlight a broader point: our anatomy can vary significantly. Just as individuals differ in their external appearances, so too does our internal anatomy.

For example, there are anatomical variations in blood vessels, organs, muscles, nerves and even bones that may not be readily visible.

Indeed, incidental findings during my own medical examinations have found I have a supernumerary (or extra) spleen, called a splenunculus, an extra flexor digitorum longus muscle (in my leg), and I’m missing both palmaris longus muscles (in my forearms).

While my anatomical variations are internal, a common example of a visible external anatomical variation are extra nipples. These can be mistaken for moles and can also result from developmental issues in the early weeks of pregnancy.

Why is this important?

Cases like the man said to have three penises are important reminders of the complexities of human anatomy and the many factors that can influence our bodies from the very start of development.

Exploring these rare findings emphasises the importance of continued research in anatomy and embryology.

These findings also highlight the importance of a healthy lifestyle for people intending to fall pregnant and who are already. This is so growing embryos can have the best chance of developing typical anatomy.

For Deaf people, train travel can be a gamble. But an AI-powered Auslan avatar can help

Source: The Conversation (Au and NZ) – By Jessica Korte, Senior Lecturer, School of Computer Science, Queensland University of Technology

For Deaf people, train travel can be a gamble. On an average day, nothing goes wrong: they catch their train to their destination and carry on with their business.

But when something out of the ordinary happens, the situation can quickly get scary, because most updates are only delivered by audio announcements. A Deaf traveller may miss their train because it was moved to a different platform, or watch as their station whizzes by because the train isn’t stopping there today. They may also remain on a train carriage in an emergency after everyone else has evacuated, and have to be rescued by station staff.

Every single one of these examples has been drawn from the real life experiences of Deaf people in Sydney. But my colleagues and I are working with Sydney Trains and members of the Australian Deaf community to develop an advanced, artificial intelligence (AI)-powered signing avatar which can automatically translate audio announcements into Auslan.

Our work on the avatar also builds towards the next step: developing AI systems which can “understand” Auslan.

Journeys don’t always go to plan

Earlier this year, my colleagues and I ran a pilot study with three Deaf train travellers in Sydney. As well as the stories they shared about what can go wrong during train travel, we learned they use tried and tested strategies for making their journeys go smoothly.

Their strategies might be familiar to regular commuters. For example, they would plan their journeys with an app, arrive early and look for signage to let them know if anything had changed.

But they also said they felt they needed to stand near information screens to watch for updates, and ask station staff or other passengers for information when the situation had changed. They also reported being hypervigilant while on the train, watching to make sure they don’t miss their stop.

But these strategies didn’t always ensure Deaf travellers received important information, including about emergencies. For example, while usually helpful, station staff were sometimes too busy to assist.

The greatest frustration came in situations where other passengers weren’t willing or able to provide information, leaving our Deaf travellers to just “follow the crowd”. This often meant ending up in the wrong place.

Developing a signing avatar

Speech-to-text software might seem like an easy solution to some of these problems. But for many Deaf people, English is not their native language and Auslan can be processed far more easily and quickly.

Our Deaf travellers told us that, in a perfect world, they would want live interpreters. However, automatic, AI-powered translation using a signing avatar displayed on a platform or train screen which could identify key words in an audio announcement, generate a sentence with correct Auslan grammar, and stitch together the corresponding signs from our vocabulary library was appealing for a number of reasons.

Avatar by Maria Zelenskaya, QUT. Auslan by Julie Lyons, QUT.

First, it allows for real-time translation of announcements that use known vocabulary – which is relevant in the trains-and-stations context, where many announcements cover similar topics.

Second, an avatar and its signing can be customised to the needs of a given situation, such as using information about screen location to ensure the avatar signs in the right direction while pointing out exits or other platforms.

Third, multiple signers can contribute signs to an avatar’s vocabulary, which can then be smoothly stitched together to make a sentence.

And importantly, an avatar means no real person has to be the “face” of an organisation’s automatically generated announcements. This is particularly important because the Australian Deaf community is small and close knit, and if something goes wrong with the translation, nobody suffers any reputational damage.

From a technical point of view, an avatar also allows us to ensure a minimum quality threshold for signing. We’re using motion capture to make sure each sign in our vocabulary library is accurate, and movements are clear.

It also helps us avoid the “uncanny valley” – an effect where something human-like but subtly wrong is unsettling. We don’t want any of the many-fingered monstrosities you may have seen recently generated by AI.

AI for everyone

This work is one step in our broader aim of creating an AI system which can understand Auslan. This AI could be used to help Deaf and hearing station staff converse, or to create “chatbot booths” or app-based assistants that would allow Deaf people to get information on demand in Auslan about their train journeys or other daily tasks.

Sign languages and Deaf cultures around the world have nuances and complexities that hearing researchers and developers of AI may not be aware of. These nuances and complexities must be embedded in new technologies, and researchers and developers must take a language-first approach to AI data collection and design with – not just for – Deaf people.

Only then will AI meet Deaf people’s real needs: to ensure their safety and independence in every aspect of daily life.

Victorian students will get ‘anti-Tate’ lessons – but much more is needed to tackle gendered violence in schools

Source: The Conversation (Au and NZ) – By Stephanie Wescott, Lecturer in Humanities and Social Sciences, Monash University

The Victorian government has announced new teaching resources to tackle the influence of “manosphere” figures, such as Andrew Tate, in the state’s schools.

This follows ongoing reports of disturbing events involving sexist abuse by students in both independent and government schools in Victoria and around the country.

But while this week’s announcement is a welcome and necessary step, we need a more comprehensive plan to eliminate gender-based violence in our schools.

What is the ‘manosphere’?

The “manosphere” is an overlapping collection of extreme men’s communities on social media that are anti-women and against women’s empowerment. This includes Tate, the “misogynist influencer” who is facing trial in Romania on charges of human trafficking and rape (which he denies).

Our recent research found women teachers are increasingly exposed to sexism, misogyny and sexual harassment as the result of boys’ exposure to “manfluencer” ideas and behaviours. These problems are further compounded by the infiltration of far-right sentiments into schools, which has been linked to far-right online forums.

At the same time, women teachers report they are not being supported by school leadership.

What’s in the Victorian resources?

The new teaching resources were developed by education academics Helen Cahill and Debbie Ollis, in consultation with teachers, students and parents.

They aim to give students skills to counter the influence of “Tate-types”, and to navigate issues such as consent, sextortion, pornography and gender-based bullying.

They will be part of respectful relationships education, which is mandatory in Victorian government schools (following a recommendation of the 2015 Royal Commission into Family Violence).

Problems with respecful relationship education

There have been implementation issues with respectful relationships education.

A 2022 review (of which one of us, Naomi Pfitzner, was an author) found problems with the funding, quality of resources and training supplied to schools, and with schools’ levels of commitment

Previous research also suggests teachers may be hesitant to engage with controversial or tricky topics. There is a risk some issues are being left out of classroom discussions.

Crucially, respectful relationships is not mandatory in all Victorian schools — independent and faith-based schools in Victoria need to opt in.

In other Australian states and territories, respectful relationships education is not compulsory in any school system.

We need more information

Education departments around the country collect various forms of data about school life, such as learning and attendance. But we don’t have accurate national data on the prevalence of gender-based violence in schools.

Without the full picture of how widespread gender-based violence is in Australian schools, it is difficult to resource and design an appropriate response.

Gender-based violence in schools is inextricably connected to the endemic levels of violence against women in Australia.

We cannot separate a broader culture that enables gendered slurs, misogyny and gender inequity — known enablers of gender-based violence — from attitudes towards women and girls in schools.

We need more information about the experiences of female students and staff in Australian schools.

What now?

Women have been raising the alarm about sexual harassment of female teachers for decades. But on top of already slow or inadequate responses, the problem has become more complex.

The proliferation of online misogynist content requires a new, tailored approach.

Our current project with Australia’s National Research Organisation for Women’s Safety is examining how online misogyny in the manosphere influences young boys and men in Australia. We will then create resources to support teachers and help make schools safer for all young people.

It is shameful many girls’ first experience of gendered violence happens as students at school. And teachers deserve a safe workplace free from misogyny and sexism.

Thou Shalt Not Steal: new Stan series is a perversely funny road trip through Central Australia

Source: The Conversation (Au and NZ) – By Kelly McWilliam, Associate Professor of Communication and Media, University of Southern Queensland

Stan/Ian Routledge

Stan Original’s newest series is coming to smaller screens, having premiered its first three episodes in September at the Toronto International Film Festival.

Thou Shalt Not Steal follows Aboriginal teen Robyn (played by the immensely talented Sherry-Lee Watson). She escapes juvenile detention and embarks on a defiant road trip from Alice Springs to Adelaide to uncover a long-held family secret.

Fellow outsider Gidge (Will McDonald) comes along for the ride. He has run away from his dodgy preacher dad Robert (Noah Taylor, clearly enjoying his character’s exaggerated grossness, from a perpetually stained singlet to overflowing ashtrays).

In hot pursuit are two incongruous duos. First come detectives Burke and Wills (Shari Sebbens and Darren Gilshenan). Then Robert teams up with the decidely crooked Maxine (played menacingly by Miranda Otto). Where Robert’s deceits are lazily self-serving, Maxine is an outback madam who poses very real dangers to the young people.

‘Some bastards have it coming …’

Thou shalt never go to Coober Pedy

Each episode begins with a tongue-in-cheek lesson from Robyn’s past. These range from the eponymous “thou shalt not steal” to “thou shalt never go to Coober Pedy”.

This deadpan humour cleverly introduces significant issues. There are the inordinate rates of incarceration of Indigenous youth, alcoholism, assault, toxic masculinity, bullying and weaponised religion, among others.

These themes are particularly pertinent in the Northern Territory, where Thou Shalt Not Steal was both set and shot. Earlier this year the NT city of Alice Springs initiated a youth curfew and the territory has now reportedly lifted its ban on using “spit hoods” on young people.

This context means some of the laughs in the series are uncomfortable. But comedy is a well-established vehicle for social justice and the show remains focused on the heroes’ journey, albeit within an important socio-political context.

Over the first six of its eight short episodes, Thou Shalt Not Steal maintains a balance between acerbic comedy and perilous road trip. Its final episodes revel in a series of over-the-top scenarios that nevertheless tie up narrative loose ends in an enjoyable way.

Indeed the shift to outright absurdity reveals the show’s gentler message: about finding a chosen family.

Miranda Otto and Noah Taylor’s characters are dangerous for different reasons.
Stan

Alice Springs (Mparntwe)

If the tone and topic of the show – described elsewhere as “End of the F…ing World meets Fargo” – sound familiar, it’s because it draws from director, co-writer and co-creator Dylan Rivers’ earlier multi-award-winning Robbie Hood (2019).

In that show, the Robin Hood mythology falls to 13-year-old Alice Springs’ local, Robbie (Pedrea Jackson). The same desert-dry humour articulates the charming teen’s well-intentioned misadventures through a variety of legal and familial landscapes.

Alice Springs (Mparntwe) is not just a recurrent muse for Rivers; it is also where he grew up, as the son of award-winning filmmakers Penelope McDonald and Warwick Thornton. Rivers has noted that, while his family actively supports each other, they are also “competitive”, pushing each other to produce their best work.

The series is set in Central and Southern Australia in the winter of 1980.
Stan/Ian Routledge

Slick and self-aware

Having worked previously with his parents on multiple productions, Thou Shalt Not Steal is also something of a family affair. Co-created and co-written with cousin Tanith Glynn-Maloney, who also serves as executive producer, Thou Shalt Not Steal was developed during COVID lockdowns. The duo slowly developed the premise and the first two episodes over two years, before securing investment and support.

The result is a slick, well-made series with terrific attention to detail. The gorgeous landscapes contrast with the dank, grimy spaces occupied by the antagonists. The soundtrack is its own treasure trove, ranging from Slim Dusty to the Yamma Family and the Warumpi Band, and always in perfect alignment to the scenes. The chorus of “almost the end, almost the end!” is a highlight in the last episode.

Rivers says he tried not to

[…] shy away from being a bit cheesy, being a bit self-aware, and being over the top at times. Hopefully there’s twists and turns that people don’t expect. But it was very consciously, like, let’s have fun.

Thou Shalt Not Steal is most definitely a fun ride.

Thou Shalt Not Steal is streaming on Stan from today.

With reports Kamala might join Joe Rogan for a chat, the US election is showing the power of podcasting

Source: The Conversation (Au and NZ) – By Lea Redfern, Lecturer, Discipline of Media and Communications, University of Sydney

Call Her Daddy/YouTube

It was big news in the podcasting world when US Vice-President Kamala Harris recently sat down with Alex Cooper’s Call Her Daddy for an extended interview. This was not just because it was one of the few times Harris has opened herself up to direct media scrutiny, but also because it signalled podcasting’s coming of age.

Now there are fresh reports she could sit down with Joe Rogan for his top-rated show. Former president Donald Trump has also said he’ll record with Rogan before election day.

High-stakes interviews are no longer solely the domain of legacy media. Politicians, like celebrities with a story to tell or a film to sell, can pop onto a podcast with a hopefully sympathetic host to reach vast and potentially new audiences. (That said, Harris also did interviews with CBS News, 60 Minutes, The View and CBS’s The Late Show with Stephen Colbert the same week.)

So for the VP and Democratic presidential candidate, is this about finding new audiences or answering to a different, perhaps softer style of interview?

Call her who?

If you haven’t heard of Call Her Daddy, note the show’s emphasis is on sex and female empowerment. Cooper’s listeners are 70% women and 76% of them are aged under 35. It is often compared to the Joe Rogan Experience, a comparison Cooper hates. Cooper has also been called the Oprah Winfrey of her generation, which may say something about her interviewing skills or her market value.

The comparisons to Rogan are hard to avoid. Call Her Daddy has been running since 2018. In 2020, Cooper split with her co-host and took the program to Spotify, also home to the Joe Rogan Experience. There, Call Her Daddy rose to be the second most-listened-to podcast globally, behind Rogan, with an average of 5 million weekly listeners. Spotify gave Cooper US$60 million to Rogan’s rumoured $250 million. This particular gender pay gap was recently reduced when Cooper took the podcast to SiriusXM for $125 million.

A Harris appearance on Rogan’s podcast could give her a larger audience than Cooper’s and parallel access to young male listeners.

‘Here’s the thing …’

Soft or smart?

Harris’ decision to be interviewed on a podcast aimed at young women brought criticism from those who saw it as the “soft option”, as well as those who don’t rate young women or approve of talk of sex.

The same commentators seem to have overlooked that for the last year, Trump has been wooing the “manosphere” and has called in to friendly bro-casts such as This Past Weekend with Theo Von. In other podcasts like Full Send, Trump has had scope for friendly freewheeling banter on topics from Ice Spice to golf.

Cooper says she also invited the former president onto her show to discuss women’s rights.

In the journalistic tradition of podcasts since Serial, Cooper revealed her process and opened her interview with Harris by sharing the reasoning behind her line of questioning. “Let’s be real, I’m probably not the one to be having the fracking conversation,” she deadpanned.

Harris said she went on the podcast “to be real, you know, and to talk about the things that people really care about”. There were moments of genuine emotion, such as anger and compassion at the death of a young woman, Amber Thurman, in Georgia in the wake of the US’s newly restrictive abortion laws. Yet at times Harris still sounded rehearsed, in the manner of people in the public eye required to repeatedly answer similar questions and give similar speeches.

The risk to a politician is that the authenticity and intimacy for which podcasting is known could just as well work against them – a lack of “realness” becomes amplified through headphones, straight into the listeners’ ears.

While Harris’ cadence sounded like familiar speechifying near the end, perhaps her anecdotes were new to sections of Cooper’s audience. For all the claims that a focus on the concerns of women made for a “soft interview”, it was also a timely reminder of the centrality of reproductive freedom to women’s lives and the election.

The risks of the interview were more Cooper’s, who hinted at the prospect of losing listeners by interviewing a politician while wanting Call Her Daddy to be “a place where everyone feels comfortable tuning in”. This is a pertinent concern for her as much of the program’s initial popularity was built on Barstool, a media company known for its conservative leanings.

A different listener

The question remains: is appearing on extremely popular podcasts with young audiences a good political strategy for Harris? The positives of appearing on Call Her Daddy were clear, given Cooper’s main audience of young women is generally more politically engaged and motivated to vote than young men.

Rogan’s audience is 81% male with 34% aged 18–35. Making a connection with young men could prove trickier for Harris within the “bro-ey”, jokey framework of the Joe Rogan Experience than it was with Cooper.

A lot will depend on Harris’ interaction with the host, but Rogan is not known for hostile interviewing and Harris is experienced in connecting with people from a range of backgrounds. And her recent spot on shock jock Howard Stern’s radio show gave her a chance to share her love of car racing.

In a tight election, which could come down to swing voters in six or seven states, such skills, showcased in the podcasting space, could impact the election. The potential gains seem worth any risks.

Why do humans have near-equal numbers of male and female babies, unlike many other animals? A new genetic study looks for clues

We know that boys and girls are produced in much the same frequency. But how – and why – is this 1:1 ratio achieved?

A new paper searches huge human data sets for gene variants that throw the 1:1 sex ratio off balance, and test the biological and theoretical rules of sex ratio.

What produces the 1:1 sex ratio?

Early scientists credited divine providence with ensuring that “every male should have its female”.

Of course, we now know that sex chromosomes are the real determiners of sex. Females have two X chromosomes; males have a single X and a male-specific Y.

The Y carries a male-determining gene called SRY, which kickstarts the differentiation of a ridge of cells into a testis. The embryonic testis makes male hormones which direct the embryo to develop as a boy. Without SRY, an alternative pathway is activated that makes an ovary, and the embryo develops as a girl.

The 1:1 ratio results from the way the X and Y chromosomes are doled out in sperm and eggs. Our cells all have two sets of chromosomes that constitute our genome, one set from each parent. A special type of cell division makes sperm and eggs with just a single set of chromosomes, so that a fertilised egg once again has two sets (one set from the sperm and the other from the egg).

So sperm all get a single copy of each chromosome – and just one sex chromosome, either an X or a Y. XX females make eggs with a single chromosome set, all of which carry an X.

When a sperm fertilises an egg, the sex chromosome the sperm carries determines the sex of the baby. Embryos that receive one X from the mother and another X from the father are destined to be XX girls, and embryos that receive a Y-bearing sperm will develop as XY boys.

So the 1:1 XY ratio in sperm should produce a 1:1 ratio of XX girls and XY boys.

Sex ratio variation

But there are lots of exceptions to a 1:1 ratio in the animal kingdom. There are genetic mutations that subvert the orderly segregation of the X and Y, or that preferentially kill male or female embryos.

Why should the sex ratio be stuck at 1:1 anyway? After all, a few males can fertilise the eggs of many females.

Indeed, for many animals, unequal sex ratios are the norm. For instance, the mouse-sized marsupial Antechinus stuartii produces only 32% males, even when assessed at birth (so it’s not that male babies die more often).

Many birds have sex ratios far from 1:1, and some show very specific adaptations that make ecological sense. For instance, the second kookaburra chick to hatch, facing a lower chance of survival, is usually a female, the sex most likely to survive.

And there are systems of non-standard sex chromosomes. Polar mammals and strange rodents, for instance, are famous for systems in which a mutant X chromosome quashes SRY to form fertile XY females, or a mutated version of SRY doesn’t work. In these species, females predominate, which makes sense for mammals that have to get all their breeding done in a short summer.

Insects take the cake. An extreme case is a kind of mite that produces a ratio of 15 females to 1 male. In many fruit fly species, 95% of sperm carry the X chromosome, so the progeny are largely female.

Why a 1:1 sex ratio in humans? Fisher’s principle

So if sex ratio is so malleable, why have humans (and most mammals) gone for a 1:1 ratio? The great British statistician Ronald Fisher proposed that the ratio is self-correcting and will tend to 1:1 unless there are evolutionary forces that select for distortions.

The argument is simple. Given every baby must have a mother and a father, if there is a deficiency in one sex, the parents of the rarer sex will have more grandchildren than parents of the more common sex.

For instance, if males are the rarer sex, parents who by chance produce more sons than daughters will leave more grandchildren than those that produce more daughters than sons. As a result, son-producing genes will get a boost until parity is reached.

So do we see measurable and heritable departures from 1:1 in the family sex ratio of human sons to daughters? What about Fisher’s principle – is there any evidence that strong evolutionary effects are constraining the human population sex ratio to be 1:1?

In the new research published this week, researchers Siliang Song and Jianzhi Zhang from the University of Michigan conducted an exhaustive examination of huge human data sets from the United Kingdom and found the answer is an emphatic no. They did identify two genetic variants that affected sex ratio, but these seemed not to be passed on through families.

So why do humans obey the 1:1 rule? Is it just statistical artefact, because any one family has relatively so few children that even large departures from a 1:1 ratio get evened out across many families?

Some families have the gene variants to produce more sons than daughters, but other families produce more daughters than sons. Song and Zhang’s analysis suggests this high variability is part of the problem for demonstrating any systematic bias.

Another possibility is that humans face special evolutionary constraints. Perhaps the human tendency for monogamy places additional evolutionary pressure on humans to adhere to Fisher’s principle in a way that does not apply to other animal species.

Whatever the answer, this paper by Song and Zhang raises many intriguing questions, and will be a stimulus to further research on the longstanding and fascinating question of parity in the human sex ratio.

Pokies? Lotto? Sports betting? Which forms of problem gambling affect Australians the most?

Source: The Conversation (Au and NZ) – By Alex Russell, Principal Research Fellow, CQUniversity Australia

ArliftAtoz2205/Shutterstock

Gambling, especially sports and race betting, is a hot political issue at the moment.

This is largely due to the recommendations from a 2023 report from a nonpartisan federal government committee, chaired by the late Peta Murphy, called You Win Some, You Lose More.

This report recommended “the Australian government, with the cooperation of the states and territories, implement a comprehensive ban on all forms of advertising for online gambling”.

This has led to lots of debate and controversy.

Recently, Peter V’landys, head of the NRL and Racing NSW, claimed lotteries were more harmful than race and sports betting combined, citing independent statistics.

Let’s explore the relative harm of different types of gambling and see if this claim holds up.

Australians love a punt

Gambling is widespread in Australia, with more than half of adults engaging in at least one form each year.

According to the latest national data, lotteries are the most common type (40% of Australians buy a ticket annually), followed by race betting (17%), pokies (16%), scratchies (15.7%) and sports betting (9.6%).

However, the popularity of a gambling form doesn’t necessarily reflect its harm. Different gambling activities have distinct characteristics.

Two key factors mean that some gambling forms are more harmful than others: the speed of gambling and bet size.

Pokies allow for frequent, small bets, with spins every three seconds. Race and sports betting can involve much larger sums and betting that is relatively fast, but still slower than pokie spins.

Sports betting, in particular, is getting faster with in-play betting and microbetting.

Poker machines, or ‘pokies’ are the biggest single source of gambling losses in Australia.

Lotteries, on the other hand, are much slower-paced.

People typically spend a small amount on tickets and wait for a draw to find out if they’ve won.

Although it’s possible to spend a lot on tickets, people tend not to, unlike with faster gambling forms.

The average spend on pokies among the 16% who play them is around $4,782 per year, compared to an average spend on lotteries of $377 per year. These are averages. Most won’t spend these amounts but some will spend far more, which raises the average amount.

V’landys’ claim about lotteries being more harmful than race and sports betting was based on “independent statistics”.

He said that of 100 people seeking help from a gambling hotline, 70 had issues with pokies, 15 with lotteries, eight with race betting, four with sports betting, and three with casinos.

We were unable to verify these figures – if anyone has the data, we’d love to see the research to assess them.

However, we do have publicly available data.

What the data say

The NSW GambleAware website’s 2020-21 report shows that of 2,886 people seeking help, 73.3% identified pokies as their primary form of gambling, while only 13 people (less than 1%) listed lotteries. Race betting accounted for 13.1%, and sports betting for 7.9%.

These patterns were consistent with previous years.

People who experience problems also usually take part in more than one form of gambling, as the NSW report showed.

When these secondary gambling activities were considered, sports betting was cited by 35.5%, race betting by 33.5%, pokies by 19.5%, and lotteries by 13.7%.

What we discovered

The best evidence on gambling problems and harm comes from large-scale prevalence studies, typically commissioned by governments and conducted by independent researchers.

These studies offer high-quality insights into how each gambling form contributes to problems.

While one prevalence study is great, our team recently combined data from seven national and state-based prevalence studies. This resulted in a very high-quality dataset that we can use to study this question.

In our analysis, we used statistical techniques to show how strongly each gambling form is associated with problems.

These techniques give us regression coefficients, which are just numbers that tell us how strong the association is. A higher number means a stronger association between that form and gambling problems.

The most problematic form was pokies (coefficient = 0.147), followed by casino games (0.136), sports betting (0.068) and race betting (0.038).

Lotteries, with a coefficient of 0.001, were the least problematic and were not statistically significant even in our large sample.

As you might guess from such a low number, there’s very little relationship between lotteries and gambling problems.

What about prevalence?

Prevalence matters too – while pokies were most strongly associated with problems, the number of people participating in each gambling form is also important.

Let’s consider an analogy – a car that gives out a lot of exhaust fumes. That car is harmful, but if virtually no one owns one, then it’s not going to account for much pollution.

The same idea applies for gambling forms. If a gambling form is very harmful but very few people do it, it doesn’t account for many problems in the population.

It works the other way, too – if there is a very clean type of car that many people drive, they also won’t add up to much pollution.

Similarly, if we have gambling forms that have very little association with problems, it won’t add up to many problems in the population, even if lots of people take part.

The regression coefficients tell us how problematic each gambling form is. Prevalance tells us how many people do it.

When we combine these two bits of information, we can work out the degree of problems in the community that come from each form.

When we did this, pokies were responsible for 52-57% of gambling problems in the community.

Sports and race betting each contributed 9-11%, with a combined total of around 20%.

Lotteries accounted for just 0.1-1% of problems.

Even if we include scratchies as part of lotteries, this only adds another 2-5% of problems, still far below sports and race betting.



The real issue

What’s the takeaway?

Lotteries are widely played but are not typically associated with much harm.

Sports and race betting, despite having fewer participants, are more harmful due to their faster pace and the potential for large, frequent bets.

Lotteries involve slower betting and lower spending, making them much less risky.

If we aim to reduce gambling harm in our community, the focus should be on pokies, which are widespread in pubs and clubs outside WA, casino games and race and sports betting.

These forms have features that make them far more harmful than slower-paced gambling like lotteries.

Social investment is back – and so are the risks of using data to target disadvantage

With the recent establishment of a new Social Investment Agency – described as a “driving project” for the government by Finance Minister Nicola Willis – it seems New Zealand has come full circle on this approach to social welfare.

First championed by then finance minister Bill English in 2015, social investment was rebranded “social wellbeing” by Labour-led governments between 2017 and 2023. But Willis signalled before last year’s election that its time had come again.

In a speech in 2022, she argued taxpayer money wasn’t being spent responsibly by the Labour administration, and that a targeted social investment approach was needed. During the 2023 election campaign, the National Party promised social investment would return.

Essentially, the policy involves using data to calculate which groups of people cost the government the most over a lifetime. Interventions aimed at reducing that cost are then targeted at those people. The idea is that early investment saves later social costs.

Right now, however, we don’t know the finer details of how Willis intends to implement the policy. But we do know how it worked in the past – and what lessons might be drawn from its earlier, short-lived implementation.

An actuarial approach to welfare

In New Zealand, the idea of social investment can be traced back to the fifth National government which held office for three terms between 2008 and 2017.

In September 2015, English outlined his approach in a Treasury lecture, explaining how the government had commissioned Australian actuary firm Taylor Fry to calculate the lifetime welfare cost to the state of people on benefits.

Typically, actuaries use statistics to calculate risk for insurance companies, information that is then used to set premiums. English said the Taylor Fry calculations would identify which beneficiary “is going to cost us the most money”.

The answer was single parents receiving a benefit. Consequently, they were deemed most in need of direct government intervention, including giving an approved mentor control of their money.

According to English’s version of social investment, data enabled the government to calculate the “forward liability” of its citizens, and target interventions accordingly.

This is not the only way to define social investment, however, and other countries often adopt a more universal approach. For example, European models tend to focus on social equality and inclusivity rather than targeting specific groups.

English’s model focused on applying benefit sanctions and conditions. The aim was to “reduce the lifetime public cost of the welfare-recipient population, thereby offering fiscal returns-on-investment, absorbed into public coffers”.

A Social Investment Unit was created in 2016, followed by a Social Investment Agency in 2017. This was a standalone agency providing advice across government departments.

No accounting for structural disadvantage

Official thinking about social investment predates the establishment of the unit and agency. In 2015, the second of two reports produced by an expert panel review of the Child, Youth and Family agency (now Oranga Tamariki) recommended a new child-centred social investment agency be created.

The report’s analysis and advice focused on intervening early to reduce the risk of vulnerable children growing up to be beneficiaries, teen parents, substance users or prisoners (among other negative outcomes).

It was suggested these potential future behaviours almost always stemmed from the actions (or inactions) of parents. Māori were identified as being especially costly due to their over-representation in child protection statistics. They were described as a “forward liability associated with poor outcomes”.

The proposed response was early intervention and social investment. That would include the removal of very young children from whānau/families where they were perceived to be at high risk. The reasoning was that the predicted damage might then never eventuate, thereby saving taxpayer dollars.

As my doctoral research found, no consideration in the report was given to the effects of systemic conditions such as poverty and the legacies of colonisation.

Costs to the state

The social investment model, with its emphasis on financial liability to the state, became a major influence on Oranga Tamariki’s practice.

It led to an increase in the early removal of tamariki Māori, especially babies, from their birth families – as demonstrated in the 2019 Hawkes Bay “uplift” case, where social workers attempted to remove a Māori baby soon after birth.

In 2017, the new Labour government promised a review of the Social Investment Agency, renaming it the Social Wellbeing Agency in 2020. The social development minister at the time, Carmel Sepuloni, said the agency would have a more holistic approach. Data would be only one of a number of considerations when delivering social services.

But with the agency now reverting to its original name, the idea of using data to guide early intervention seems to be central again. It’s unclear, however, whether the actuarial approach of Bill English’s earlier model will return.

Nicola Willis does seem to be aware of the criticism of the English-era model’s apparent focus on fiscal risk and returns. She has stressed that measuring other outcomes is also important.

As yet, though, there is no indication the policy’s highly targeted approach to welfare will account for structural factors such as colonisation and poverty.

Given the government’s drive to remove any special policy considerations based on te Tiriti of Waitangi/Treaty of Waitangi, the risk remains that some Māori will again come to be viewed as a “cost” to the state.

New research shows most space rocks crashing into Earth come from a single source

Source: The Conversation (Au and NZ) – By Trevor Ireland, Professor, School of the Environment, The University of Queensland

The sight of a fireball streaking across the sky brings wonder and excitement to children and adults alike. It’s a reminder that Earth is part of a much larger and incredibly dynamic system.

Each year, roughly 17,000 of these fireballs not only enter Earth’s atmosphere, but survive the perilous journey to the surface. This gives scientists a valuable chance to study these rocky visitors from outer space.

Scientists know that while some of these these meteorites come from the Moon and Mars, the majority come from asteroids. But two separate studies published in Nature today have gone a step further. The research was led by Miroslav Brož from Charles University in the Czech Republic, and Michaël Marsset from the European Southern Observatory in Chile.

The papers trace the origin of most meteorites to just a handful of asteroid breakup events – and possibly even individual asteroids. In turn, they build our understanding of the events that shaped the history of the Earth – and the entire solar system.

What is a meteorite?

Only when a fireball reaches Earth’s surface is it called a meteorite. They are commonly designated as three types: stony meteorites, iron meteorites, and stony-iron meteorites.

Stony meteorites come in two types.

The most common are the chondrites, which have round objects inside that appear to have formed as melt droplets. These comprise 85% of all meteorites found on Earth.

Most are known as “ordinary chondrites”. They are then divided into three broad classes – H, L and LL – based on the iron content of the meteorites and the distribution of iron and magnesium in the major minerals olivine and pyroxene. These silicate minerals are the mineral building blocks of our solar system and are common on Earth, being present in basalt.

“Carbonaceous chondrites” are a distinct group. They contain high amounts of water in clay minerals, and organic materials such as amino acids. Chondrites have never been melted and are direct samples of the dust that originally formed the solar system.

The less common of the two types of stony meteorites are the so-called “achondrites”. These do not have the distinctive round particles of chondrites, because they experienced melting on planetary bodies.

The asteroid belt

Asteroids are the primary sources of meteorites.

Most asteroids reside in a dense belt between Mars and Jupiter. The asteroid belt itself consists of millions of asteroids swept around and marshalled by the gravitational force of Jupiter.

The interactions with Jupiter can perturb asteroid orbits and cause collisions. This results in debris, which can aggregate into rubble pile asteroids. These then take on lives of their own.

It is asteroids of this type which the recent Hayabusa and Osiris-REx missions visited and returned samples from. These missions established the connection between distinct asteroid types and the meteorites that fall to Earth.

S-class asteroids (akin to stony meteorites) are found on the inner regions of the belt, while C-class carbonaceous asteroids (akin to carbonaceous chondrites) are more commonly found in the outer regions of the belt.

But, as the two Nature studies show, we can relate a specific meteorite type to its specific source asteroid in the main belt.

One family of asteroids

The two new studies place the sources of ordinary chondrite types into specific asteroid families – and most likely specific asteroids. This work requires painstaking back-tracking of meteoroid trajectories, observations of individual asteroids, and detailed modelling of the orbital evolution of parent bodies.

The study led by Miroslav Brož reports that ordinary chondrites originate from collisions between asteroids larger than 30 kilometres in diameter that occurred less than 30 million years ago.

The Koronis and Massalia asteroid families provide appropriate body sizes and are in a position that leads to material falling to Earth, based on detailed computer modelling. Of these families, asteroids Koronis and Karin are likely the dominant sources of H chondrites. Massalia (L) and Flora (LL) families are by far the main sources of L- and LL-like meteorites.

The study led by Michaël Marsset further documents the origin of L chondrite meteorites from Massalia.

It compiled spectroscopic data – that is, characteristic light intensities which can be fingerprints of different molecules – of asteroids in the belt between Mars and Jupiter. This showed that the composition of L chondrite meteorites on Earth is very similar to that of the Massalia family of asteroids.

The scientists then used computer modelling to show an asteroid collision that occurred roughly 470 million years ago formed the Massalia family. Serendipitously, this collision also resulted in abundant fossil meteorites in Ordovician limestones in Sweden.

In determining the source asteroid body, these reports provide the foundations for missions to visit the asteroids responsible for the most common outerspace visitors to Earth. In understanding these source asteroids, we can view the events that shaped our planetary system.

A new book reveals much of Trump’s success is based on a myth he is a self-made billionaire

Source: The Conversation (Au and NZ) – By John Hawkins, Senior Lecturer, Canberra School of Politics, Economics and Society, University of Canberra

Lucky Loser tells the story of Donald Trump’s less-than-stellar business career and how he was able to misrepresent it as a success.

It is written by New York Times investigative journalists, Russ Buettner and Susanne Craig. Both have won Pulitzer Prizes for earlier analyses of Trump. Another badge of honour is Trump sued them – and lost.

They are by no means the first writers to expose the Potemkin village that is Trump’s business empire. A telling insider account came from Trump’s niece, psychologist Mary Trump, who revealed the creator of Donald’s fortune was his father Fred.


Lucky Loser: How Donald Trump Squandered His Father’s Fortune and Created the Illusion of Success – Russ Buettner and Susanne Craig (Bodley Head)


Setting things straight

However, at more than 500 pages, including more than 40
pages of notes on sources, this new book is the most comprehensive rendering. It is detailed, clearly written and has been well-reviewed in the financial press and by economic historian Brad de Long.

The authors aim to draw on financial statements and interviews to “set straight Donald Trump’s chaotic onslaught of untruths and misdirection”.

A large part of the Trump mythology is the lie that he is a self-made billionaire. In the presidential debate with Hillary Clinton, Trump sought to downplay the contribution of his father, saying “my father gave me a very small loan”. The book reveals his father’s contribution, in today’s money, was around half a billion US dollars.

Trump’s first piece of luck was being born the son of hard-working, cautious and competent residential property developer Fred Trump, the son of a German immigrant. His second was that Fred’s eldest son did not have the ruthless drive to become Fred’s successor, and Fred did not consider his daughters as potential successors. So despite some characteristics that were the antithesis of his father, Donald became his heir.

The book describes Fred’s career in some detail. The first hundred pages are mostly about him. Once Fred stepped back, Trump diversified his father’s company to form what the authors term

an eclectic conglomerate untethered from any core competency.

Another piece of luck was been chosen to star in the reality television series The Apprentice, from which he made a lot of money, including from licensing deals, for the small amount of time he spent on it.

The producers of this series have a lot to answer for, as they wanted to present their star as the astute businessman they knew him not to be. As they said, it was “not a documentary”. But it enormously and misleadingly raised Trump’s profile.

Wins followed by losses

The authors describe how some of Trump’s ventures, such as the development of Trump Tower, went well as the Manhattan property market boomed. He also profited from some “greenmailing” (buying shares in a company with the stated or implied intention of taking it over and then selling the shares at a higher price), facilitated by exaggerated accounts in the media of his wealth.

But Trump used up much of the proceeds of his few successes covering his losses on a range of his other business ventures.

Among his notable failures was Trump University, where he paid A$37 million to settle lawsuits for fraud. Many other property projects, Scottish golf courses, Trump Ice bottled water and Trump Mortgage, never turned a profit. And the punters were not the only ones losing money in Trump casinos.

While he has fought to keep them secret, what has emerged from Trump’s tax returns are a series of huge losses.

A conundrum not really addressed in the book is why so many bankers were willing to lend to him.

What would a second Trump presidency mean for the global economy?


The book concentrates on Trump’s career before the 2016 election, when the flawed US electoral system turned his almost 3 million vote loss on the popular vote into a win in the electoral college. As president, he disregarded conflicts of interest. As the authors note, parties wanting to influence the president could funnel money to him by booking blocks of rooms at his hotel.

After 81 million Americans voted to fire him in 2020, Trump’s businesses again performed poorly.

Trump’s current wealth is estimated by Forbes at A$5.7 billion (less than it was a decade ago). But about half of this is from his majority stake in Truth Social, promoted as a right-wing alternative to Twitter. (Now, it could be said, an even more right-wing forum than X.) It has tiny and falling revenues and makes large losses. If Trump loses the election, its value will probably soon be close to zero. It is regarded as a “meme stock”.

Buettner and Craig conclude Trump “would have been better off betting on the sharemarket than on himself”. Analysis cited in The Economist in 2018 concluded that had Trump just put the money from his father into a sharemarket index fund he would have had A$2.9 billion in 2018. Given subsequent rises in the US stockmarket that would have grown to around A$5.9 billion by now, more than most estimates of his wealth.

Forbes reached a similar conclusion, as did De Long and US political commentator Professor Robert Reich. The self-described business genius destroyed rather than created value.

A poor tycoon and a poor president

This business record of mismanaging an inheritance is reflected in Trump’s economic performance as president. He inherited the world’s largest economy from Obama. By the end of his term it was more than 10% smaller than China’s economy. Historians rank him one of the worst performing presidents on economic management (and much else). The public gave him the lowest approval ratings during his presidential term.

Trump has indeed been a “lucky loser”. But if this deeply flawed man is returned to the presidency, the world will be an unlucky loser.

Why do I have hay fever? I didn’t have it as a child

Hay fever (or allergic rhinitis) is a long-term inflammatory condition that’s incredibly common. It affects about one-quarter of Australians.

Symptoms vary but can include sneezing, itchy eyes and a runny or blocked nose. Hay fever can also contribute to sinus and ear infections, snoring, poor sleep and asthma, as well as lower performance at school or work.

But many people didn’t have hay fever as a child, and only develop symptoms as a teenager or adult.

Here’s how a combination of genetics, hormones and the environment can lead to people developing hay fever later in life.

Remind me, what is hay fever?

Hay fever is caused by the nose, eyes and throat coming into contact with a substance to which a person is allergic, known as an allergen.

Common sources of outside allergens include airborne grass, weed or tree pollen, and mould spores. Pollen allergens can be carried indoors on clothes, and through open windows and doors.

Depending on where you live, you may be exposed to a range of pollen types across the pollen season, but grass pollen is the most common trigger of hay fever. In some regions the grass pollen season can extend from spring well into summer and autumn.

How does hay fever start?

Hay fever symptoms most commonly start in adolescence or young adulthood. One study found 7% of children aged six had hay fever, but that grew to 44% of adults aged 24.

Before anyone has hay fever symptoms, their immune system has already been “sensitised” to specific allergens, often allergens of grass pollen. Exposure to these allergens means their immune system has made a particular type of antibody (known as IgE) against them.

During repeated or prolonged exposure to an allergen source such as pollen, a person’s immune system may start to respond to another part of the same allergen, or another allergen within the pollen. Over time, these new allergic sensitisations can lead to development of hay fever and possibly other conditions, such as allergic asthma.

Why do some people only develop hay fever as an adult?

1. Environmental factors

Some people develop hay fever as an adult simply because they’ve had more time to become sensitised to specific allergens.

Migration or moving to a new location can also change someone’s risk of developing hay fever. This may be due to exposure to different pollens, climate and weather, green space and/or air quality factors.

A number of studies show people who have migrated from low- and middle-income countries to higher-income countries may be at a higher risk of developing hay fever. This may due to local environmental conditions influencing expression of genes that regulate the immune system.

2. Hormonal factors

Hormonal changes at puberty may also help drive the onset of hay fever. This may relate to sex hormones, such as oestrogen and progesterone, affecting histamine levels, immune regulation, and the response of cells in the lining of the nose and lower airways.

3. Genetic factors

Our genes underpin our risk of hay fever, and whether this and other related allergic disease persists.

For instance, babies with the skin condition eczema (known as atopic dermatitis) have a three times greater risk of developing hay fever (and asthma) later in life.

Having a food allergy in childhood is also a risk factor for developing hay fever later in life. In the case of a peanut allergy, that risk is more than 2.5 times greater.

What are the best options for treatment?

Depending on where you live, avoiding allergen exposures can be difficult. But pollen count forecasts, if available, can be useful. These can help you decide whether it’s best to stay inside to reduce your pollen exposure, or to take preventative medications.

You may also find alerts on thunderstorm asthma, where pollens combine with specific weather conditions to trigger breathing difficulties.

If you have mild, occasional hay fever symptoms, you can take non-drowsy antihistamines, which you can buy at the pharmacy.

However, for more severe or persistent symptoms, intranasal steroid sprays, or an intranasal spray containing a steroid with antihistamine, are the most effective treatments. However, it is important to use these regularly and correctly.

Allergen immunotherapy, also known as desensitisation, is an effective treatment for people with severe hay fever symptoms that can reduce the need for medication and avoiding allergens.

However, it involves a longer treatment course (about three years), usually with the supervision of an allergy or immunology specialist.

When should people see their doctor?

It is important to treat hay fever, because symptoms can significantly affect a person’s quality of life. A GP can:

  • recommend treatments for hay fever and can guide you to use them correctly

  • organise blood tests to confirm which allergen sensitisations (if any) are present, and whether these correlate with your symptoms

  • screen for asthma, which commonly exists with hay fever, and may require other treatments

  • arrange referrals to allergy or immunology specialists, if needed, for other tests, such as allergen skin prick testing, or to consider allergen immunotherapy if symptoms are severe.

‘Nature markets’ may help preserve biodiversity – but they risk repeating colonial patterns of Indigenous exploitation

Source: The Conversation (Au and NZ) – By David Hall, Senior Lecturer in Social Sciences and Public Policy, Auckland University of Technology

As the latest global biodiversity summit gets underway in Colombia, finance for the conservation and restoration of nature is one of the key themes of negotiations.

Global wildlife populations have shrunk by an average of 73% in the past 50 years, according to the 2024 Living Planet report. Consequently, momentum is growing worldwide to deliver new nature markets, such as biodiversity credits, to unlock new sources of funding.

Basically, nature markets are systems of exchange that match demand for nature regeneration with a supply of nature-positive projects.

But this creates risks, as well as opportunities, for Indigenous peoples. Without due care for data sovereignty, Indigenous communities may lose out yet again.

Nature markets could enable Indigenous peoples to fulfill their duties of guardianship. But such markets could also forge a new form of colonialism, including enclosure and appropriation of habitats and species that Indigenous peoples have traditional connections to.

Efforts to prevent deforestation have at times displaced Indigenous people.

This can occur overtly through formalisation of property rights over species, ecosystems and associated lands or waters. For example, efforts to reduce emissions from deforestation (REDD+) in developing countries have been troubled by instances where Indigenous communities were dispossessed from ancestral lands, alienated from place-based traditions or excluded from the commercial benefits of carbon trading.

The current surge for nature markets is attentive to these risks, with international commitments to avoid such mistakes. Yet the processes of colonialism can be less overt and more insidious.

Indigenous data

One neglected area is Indigenous data. This relates to traditional and cultural information, population data, oral histories and ancestral knowledge relating to the environment and natural resources.

If care is not taken with Indigenous data, there are serious risks of reproducing colonialist patterns of exploitation.

Data represents reality. Data helps decision makers to know whether their interventions are effective, even when they are far away from the ecosystems being protected or restored.

If data are accurate, authentic and timely, a funder does not need to set foot in a remote habitat to know whether its carbon stock or native species abundance are improving or declining.

Biodiversity credits represent one way to operationalise a nature market. They are basically a vehicle for data. The emerging methodologies are bundles of metrics and indicators that track biodiversity and ecological function.

Biodiversity credits use metrics and indicators that track ecological function.
Renee Raroa, CC BY-SA

The data enable credit holders to make credible claims of biodiversity uplift, or avoided biodiversity loss, as a consequence of credit sales.

As a representation of ecological reality, data are at least one step removed from the habitats and species they represent. This opens up the potential for nature markets to rely on the exchange of verifiable data, without the need to commodify nature itself, and therefore impinge on the ownership rights of Indigenous communities.

However, data are not free from such considerations. To divert data into a system of market exchange raises a different but related set of concerns about ownership, benefit and sovereignty.

The rise of Indigenous data sovereignty

Indigenous data sovereignty is the right of Indigenous peoples to govern the collection, ownership and application of data about Indigenous communities, peoples, lands and resources. It relates to data produced by and about Indigenous peoples and the environments they have relationships with.

Nature and people are precious, so data that represent nature and people are imbued with that preciousness. As Māori practitioner Ngapera Riley has written:

Data is a taonga (treasure). It’s something that people gift us, and that we gift to others as we go about our daily lives.

In te ao Māori, data come in many forms. This includes whakataukī (proverbs), moteatea (chants), whaikorero (oratory), maramataka (calendar), whakapapa (genealogies), pūrākau (stories) and increasingly digital forms.

Consequently, we must take great care in how data are accessed, shared, stored and used. This is especially critical in a system of market exchange. The dominant markets of today are profit-driven, creating incentives for appropriation and exploitation.

Sovereignty means power

Indigenous peoples are conscious that, while there are risks in data and knowledge sharing, there are also opportunities. Indigenous data and knowledge is a living and evolving system, which can contribute to effective responses to environmental challenges, including the protection and regeneration of biodiversity.

The principles of Indigenous data governance emerged from deliberations about how to protect Indigenous sovereignty when sharing knowledge and data for academic research. These CARE principles hold that Indigenous data should be governed for collective benefit, authority to control, responsibility and ethics.

This is critically important in ecological research, which too often neglects duties relating to data about natural ecosystems and the people who live within them.

It is troubling that the recognition of Indigenous data sovereignty is largely lacking from the discussion of nature markets so far. Unless Indigenous data sovereignty is upheld, the legitimacy of nature markets will likely be irreversibly tarnished.

This is why, in a recent Biodiversity Credits Alliance discussion paper, we included Indigenous data sovereignty as a risk to be identified, understood and managed.

But Indigenous data sovereignty is more than a risk: it is a source of power. It is a right to self-determination, to choose how data are used and their value is distributed. By ensuring this right, nature markets might deliver on their promise of inclusive, sustainable prosperity.

More than 20% of Earth’s plant species are found only on islands – and time is running out to save them

Source: The Conversation (Au and NZ) – By Julian Schrader, Lecturer in Plant Ecology, Macquarie University

Islands have long intrigued explorers and scientists. These isolated environments serve as natural laboratories for understanding how species evolve and adapt.

Islands are also centres of species diversity. It has long been speculated that islands support exceptionally high amounts of global biodiversity, but the true extent was unknown until now.

In world-first research published in Nature today, my colleagues and I counted and mapped the diversity of plant life on Earth’s islands. We found 21% of the world’s total plant species are endemic to islands, meaning they occur nowhere else on the planet.

These findings are important. Island plants are at higher risk of extinction than those on mainlands. Detailed knowledge of plants species, and where they grow, is essential for monitoring and conserving them.

Mapping island floras worldwide

The study involved an international team of scientists. We developed an unprecedented database of vegetation information from more than 3,400 geographical regions worldwide, including about 2,000 islands.

The definition of an island is somewhat arbitrary. Conventionally, an island is a landmass entirely surrounded by water and smaller than a continent. This means Tasmania and New Guinea are islands, but mainland Australia – a continent in itself – is not. This is the definition we used.

We found 94,052 plant species, or 31% of the world’s total, are native to islands. Of these, 63,280 plant species, or 21%, only occur on islands.

Endemic species were concentrated on large tropical islands such as Madagascar, New Guinea and Borneo. On Madagascar alone, 9,318 plant species – 83% of its total flora – grow there and nowhere else.

Fewer plant species overall were found at ocean archipelagos such as Hawaii, the Canary Islands and the Mascarenes (east of Madagascar, including La Reunion and Mauritius). But a large share of their species were still unique to these islands.

Two palms are endemic to Australia’s Lord Howe Island – Howea forsteriana and H. belmoreana. They are one of the best-researched examples of “sympatric speciation”, or in other words, species that evolve from a common ancestor at the same location.

This mode of evolution has long been hypothesised to exist. But examples are rare, and highly useful for evolutionary research.

The Norfolk Island Pine (Araucaria heterophylla) is, of course, named after the tiny island where it is found. This species, while endangered in the wild, is now widely planted along Australia’s beaches where it is instantly recognisable to us.

Islands are of great conservation concern

Islands cover just 5.3% of the world’s land area, but contribute disproportionately to global biodiversity.

Island plants are at much greater risk of extinction than species found in mainland areas, for reasons such as:

  • small population sizes
  • unique evolutionary traits that make them vulnerable to invasive species such as herbivores
  • specific habitat requirements
  • habitat degradation
  • threats from invasive plant and animal species
  • climate change.

Some 57% of the island-endemic species we assessed are considered critically endangered, endangered, vulnerable, or near-threatened, according to the International Union for Conservation of Nature.

Alarmingly, 176 of plant species endemic to islands are already classified as extinct, accounting for 55% of all known extinct plant species globally. Among these is Hawaii’s vulcan palm (Brighamia insignis), which is now considered extinct in the wild. However, the species is popular as an ornamental plant and still survives in gardens.

Hawaii’s vulcan palm is extinct in the wild, but is popular as an ornamental plant.

Other species might be less lucky; extinction in the wild may mean being lost for ever.

So, assessing the conservation status of island floras is important. Under a globally agreed United Nations target, 30% of the world’s land and oceans should be protected by 2030. We calculated how much of global islands is conserved today. Disappointingly, only 6% of endemic plant species occur on islands that meet this target.

For instance, New Caledonia, Madagascar and New Guinea – known for their many endemic plant species – contain relatively low levels of protected areas.

Assessing the conservation status of island floras is important.

Protecting our island plants

Urgent action is needed to protect island biodiversity. This includes expanding protected areas, prioritising regions with high numbers of endemic species, and implementing habitat restoration projects.

Without such measures, the unique floral diversity of islands may continue to decline, with potentially severe consequences for global biodiversity.

Much more research is needed to determined the best conservation strategies for all these plant species. Accurate data is vital to guide future conservation strategies and safeguard against further loss.

Our study also serves as a stark reminder of the urgent need for targeted plant conservation efforts on islands. Many species teeter on the brink of extinction, and time is running out to preserve this irreplaceable natural heritage.

Ocean eddy currents funnel extreme heat and cold to the life-filled depths

Source: The Conversation (Au and NZ) – By Ming Feng, Senior Principal Research Scientist, CSIRO

Letowa/Shutterstock

On land, we’re familiar with heatwaves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold.

Marine heatwaves and cold spells can severely damage ocean ecosystems and habitats such as coral reefs. These extremes can also force species to move or die and cause sudden losses for fisheries.

In research published today in Nature, we show almost half of the heatwaves and cold snaps reaching the ocean’s twilight zone – between 200 and 1,000 metres – are driven by large eddy currents, swirling currents which transport warm or cold water.

As the oceans heat up, heatwaves linked to eddy currents are getting more intense – and so are cold snaps. These pose potential threats to the vast amount of life in the twilight zone, home to the world’s most abundant vertebrate and the largest migration on the planet.

Monitoring the deep sea is hard

About 90% of heat trapped by greenhouse gases has gone into the oceans. As a result, marine heatwaves are arriving more frequently – especially off Australia’s east coast, Tasmania, the northeast Pacific coast in the United States and in the North Atlantic.

Researchers have long relied on satellite measurements of temperatures at the ocean surface to detect these extreme ocean temperature events. Surface temperatures are directly influenced by the atmosphere. But it’s different at depth.

Satellites can’t measure temperatures under the surface, making the deep sea much harder to monitor.

Instead, we have a handful of long-term moorings – measurement buoys suspended at depth – across the world’s oceans. These are hugely valuable, as they continuously record temperatures and make it possible to detect extremes temperature changes.

In recent decades, there have been welcome advances in the form of Argo floats – robotic divers which dive 2,000 metres deep and resurface, sampling temperature and salinity as they go.

Data from these two sources coupled with traditional measurements from vessels made our research possible.

Heatwaves inside eddy currents

The data gave us two million high quality temperature readings or “profiles” across the world’s oceans, spanning three decades. We used this rich data to uncover the role of eddy currents.

Ocean eddies are huge loops of swirling current, sometimes hundreds of kilometres across and reaching down over 1,000 metres. They’re so large you can see them on satellite images.

These powerful currents can push warm surface water down deeper or lift deep cold water up, causing rapid temperature changes. Eddies can travel a long distance before dissipating, carrying bodies of colder or warmer water with them.

We discovered their role in triggering deep heatwaves and cold snaps by examining each temperature profile and cross-matching this with eddies present at the same time and location.

This showed eddies played a major role in triggering marine heatwaves and cold spells in waters deeper than 100 metres – especially in the mid-latitude oceans north and south of the tropics.

The East Australian Current takes warm water southward down the east coast, triggering many eddies. More than 70% of deeper marine heatwaves in this area actually took place inside ocean eddies.

When eddies in this current spin anticlockwise, they tend to bring marine heatwaves, transporting warm water to the depths. But when they spin clockwise, they bring cold deep water up higher, bringing cold spells.

We found deep extreme temperature events linked to eddies are seen more often in major ocean boundary currents, such as the East Australian and Kuroshio currents in the Pacific and the Gulf Stream in the Atlantic. Deep marine heatwaves also occur in the Leeuwin Current off Western Australia. The stronger the eddy currents, the more likely they are to trigger extreme temperatures deeper down.

Eddy currents are the main driver for nearly half of all deep ocean heatwaves and cold spells. Other drivers include ocean temperature fronts from strong ocean currents and large-scale ocean waves.

When eddy currents spin one way, they can send heat to the depths. When they spin another, they can bring cold water towards the surface.
olrat/Shutterstock

What does this mean for ocean life?

Day in, day out, heat trapped by greenhouse gases makes its way to the oceans.

You would expect marine heatwaves to increase, which they are. But cold snaps haven’t gone away. In fact, extremes of both heat and cold are getting more intense in the deeper ocean as the climate changes.

Our research suggests eddy currents are acting to magnify the warming rates of marine heatwaves and the cooling rate of the cold spells. Warmer oceans overall are leading to stronger eddy currents, which in turn are able to trigger large temperature change over a greater vertical distance.

Because we can detect ocean eddies with satellites, we can use this research to predict when deeper marine heatwaves and cold spells are likely. This will help find which ecosystems are likely to be hit by extreme heat or cold and assess what damage they do.

The ocean layer these extremes affect is called the twilight zone – between 200 and 1,000 metres deep. These depths are home to many important fish species and plankton. In fact, this zone has more fish biomass than the rest of the ocean combined. One small fish, the bristlemouth, is likely the most abundant vertebrate on earth, potentially numbering in the quadrillions – thousands of trillions.

The mesopelagic Twilight Zone is rich in life. Clockwise from top: mesopelagic jellyfish, viperfish, lanternfish, larvacean, copepod and squid.

When night falls, vast numbers of fish, crustaceans and other creatures migrate towards the surface to feed in the largest animal migration on Earth. During the day, many open ocean fish head to the twilight to avoid sharks, whales and other surface predators.

Heat and cold brought by eddies aren’t the only threat to the twilight zone. Marine heatwaves can lead to low oxygen levels in the water and reduced nutrients. We will need to find out what threat these combined changes pose to life in the twilight.

Australia donates 49 Abrams tanks to Ukraine

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Defence Department Supplied Photo

The Albanese government is giving 49 M1A1 Abrams tanks to Ukraine, despite earlier this year apparently playing down the prospect of the donation.

The latest Australian package is worth A$245 million. It brings the total Australian military aid to Ukraine since the full-scale Russian invasion in 2022 to A$1.3 billion, and overall Australian support to A$1.5 billion.

When asked about a possible gift of the tanks in February, Defence Minister Richard Marles said it was “not on the agenda”.

Government sources say donating the tanks required US approval since Australia had purchased them from Washington, so there had been a process to go through.

Minister for Defence Industry and Capability Delivery Pat Conroy, who is on his way to the NATO defence ministers meeting in Brussels, announced the decision in London. In Brussels, Conroy will meet with the Ukraine defence minister.

Australia, New Zealand, Japan and South Korea form the “Indo-Pacific Four” group of non-NATO countries attending the meeting.

The 49 tanks are near the end of their life, so a small number will have to be repaired before they are delivered. Alternatively, they could be used as spare parts if Ukraine wants them delivered more quickly. Ukraine will decide which option to pursue.

The Australian army is retaining a handful of the M1A1 Abrams to help the transition to the M1A2 fleet of tanks.

Conroy said: “We stand shoulder-to-shoulder with Ukraine in their fight against Russia’s illegal invasion. These tanks will deliver more firepower and mobility to the Ukrainian armed forces, and complement the support provided by our partners for Ukraine”.

View from The Hill: Albanese would be better off if the story wasn’t ‘all about him’

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Unless the government pulls up its political socks, Anthony Albanese could find himself spending a good deal of time in his  spectacular new home, with its uninterrupted ocean views, sooner than he wishes.

This week’s Newspoll has the Coalition moving in front on a two-party basis for the first time, with Labor’s primary vote at 31%.

Albanese would hope for another full term as prime minister. But if Labor fell into minority government at next year’s election, there would likely be pressure before too long to replace him. He would not be seen as a good bet for the 2028 election.

If Peter Dutton pulled off a miracle win in a few months, Albanese could be regularly whale watching this time next year.

Since the PM’s purchase of the $4.3 million house at the wonderfully-named Copacabana, was revealed on Tuesday,  two narratives have contended.

Critics denounce Albanese as “tone deaf” in his timing during a housing affordability crisis.

It was more than awkward that just hours after the news broke, Albanese was appearing with minister Clare O’Neil in Queensland to make an announcement about  housing.

The Copacabana house is a story made for that renter-in-perpetuity, Greens spokesman Max Chandler-Mather.

Dutton, who has bought and sold a few properties in his time, is careful with his words, knowing others will stir the outrage.

The alternative narrative is that Albanese, marrying for a second time next year, is entitled to a private life. This involves reordering his property arrangements ahead of a wedding.

Moreover, some observe, the criticism of him is the “politics of envy” or the “tall poppy syndrome”.

But there’s another narrative. Suddenly, Albanese’s story has become “all about him” again, as it regularly does when he reverts to talking about his humble origins.

Stressed voters could be forgiven for being impatient, or cynical about Albanese’s protestations this week that although he now has a good income, “I also know what it’s like to struggle”.

My mum lived in the one public housing that she was born in for all of her 65 years. And I know what it’s like, which is why I want to help all Australians into a home, whether it be public homes or private rentals or home ownership.

Unfairly or not, the house story will be read by some as a prime minister spending time on his own affairs.

Buying a house is a major and reasonably time-consuming process, unless it was outsourced it to partner, Jodie Haydon. The Central Coast was chosen because her family lives there.

The narrative can also be cast to look like Albanese is preparing for his post-political life while he is still the most important individual in politics.

Whether this is accurate becomes beside the point, in this era when perceptions can be paramount.


from Realestate.com, CC BY

Unsurprisingly, he was asked whether he planned to retire at the house. “I’m planning to be in my current job for a very long period of time,” he said.

In mid-1991 Bob Hawke purchased a property overlooking Sydney Harbour with a jetty and “stunning views”, and a price tag of $1.23 million.

Hawke’s leadership was already on the decline – by year’s end he was replaced by Paul Keating.

Apart from the bad publicity for Albanese, the house affair has taken a good deal of attention from what the government wanted to talk about, notably, what it’s doing to protect consumers and the like.

It has meant his ministerial colleagues are forced to defend him when they are confronted with awkward questions.

Energy Minister Chris Bowen tried to make the best fist of it that he could, when quizzed during an interview.

“Every Australian is entitled to buy and sell property. Now Anthony cops it when he sells the property. He cops it when he provides a rent holiday to his tenants. He cops it when he buys a property,” he said.

“I think most average Australians say, fair enough. You know, this is what aspiration is about, most average Australians say, well, you know, we all buy and sell properties.”

When you are in the public eye it is not, however, such an ordinary story.

By the way, when Albanese goes to the G20 in Rio de Janeiro next month, he can get to see the real Copacabana.

Charles III will be the first king of Australia to visit our shores. He could also be the last

Source: The Conversation (Au and NZ) – By Jess Carniel, Associate professor in Humanities, University of Southern Queensland

King Charles III and Queen Camilla’s upcoming visit to Australia is significant for several reasons. It is Charles’ first visit since ascending to the throne – as well as the first time a British male head of state has visited Australia.

Some observers are also wondering whether it might be one of the last royal tours, as debates about Australia potentially becoming a republic are reignited.

As the monarchy tries to “modernise” alongside growing support for republicanism, this visit will be one to watch.

The curse of the Antipodes?

As Prince of Wales, Charles had a long and successful track record of royal tours to Australia, having visited 16 times. The visits included a term attending Geelong Grammar School in 1966, as well as the 1983 tour with Princess Diana that saw Australians caught up in Di-mania – and Charles reportedly gripped by jealousy.

But Charles’ royal predecessors weren’t as lucky in their trips down under. His own grandfather, King George VI, planned to visit Australia in the late 1940s with Queen Elizabeth and Princess Margaret, but the tour was postponed due to his poor health. While he had previously visited as the Duke of York, George VI never made it here as king.

King George VI was born in 1895 and reigned from 1936 until his death in 1952.

The very first royal visit to Australia – Prince Alfred’s 1867 tour – had all appearance of being cursed. One of his crew members drowned during the first stop in South Australia. Several more people died in a major fire accident and a Catholic-Protestant skirmish in Melbourne.

Most memorably – certainly for Alfred – was an assassination attempt on the prince in Sydney. This, interestingly, is an experience King Charles has also had.

During Charles’ 1994 visit, student protester David Kang fired blanks from a starter pistol in protest of Australia’s treatment of Cambodian refugees. The then Prince of Wales wasn’t harmed and Kang went on to become a barrister.

For non-British royals, however, Sydney has been a lucky location. King Frederick X’s decidedly modern romance with Tasmania-born Queen Mary famously began when they met at a bar during the Sydney Olympics in 2000.

Prince or king – does it matter?

This will be Charles’ seventeenth visit to Australia, but his first as reigning monarch. This means he is visiting not on behalf of the head of state, but as the head of state.

The royal couple’s planned Australian engagements are as strategic as they are symbolic. They reflect carefully curated and ostensibly “non-political” issues such as environmental sustainability, cancer research and family violence.

The visit also includes a meeting with Indigenous representatives. Notably, it is the first royal tour to not use the term “walkabout” to describe public meet-and-greets, as this term had been criticised as cultural appropriation.

It seems Charles’ modernised monarchy is seeking to distance itself from overtly colonial language – as much as a foreign monarchy can, anyway. The king has yet to respond to Indigenous leaders calling for an apology for British colonisers’ genocides of First Nations peoples.

Although the Australian media has focused on the stops in Canberra and Sydney, the main purpose of the tour is for the king to attend the Commonwealth Heads of Government Meeting in Samoa between October 21 and 26.

It is the first time the meeting will be hosted by a Pacific Island state. The talks are an important opportunity for the king to highlight issues such as climate change, to which small island states in the Pacific are particularly vulnerable.

Are people happy about the visit?

All six state premiers have declined their invitations to meet the king at his welcome reception in Canberra, citing other commitments. Their excuses might be genuine in some cases. For example, Queensland Premier Steven Miles is in the last few weeks of an election campaign.

However, critics from the monarchist camp have viewed the move as a political response to debates over whether Australia should remain a constitutional monarchy with the king as its head of state.

A YouGov Australia poll published on the first anniversary of Charles’s ascension showed Australians are divided on republicanism. While 32% want to become a republic “as soon as possible”, 35% preferred to remain a constitutional monarchy and 12% wanted to become a republic after the king’s death. The remaining respondents didn’t know.

Notably, the poll found republican sentiment had increased since Queen Elizabeth II’s death in September 2022.

The Albanese government established an assistant minister for the republic upon entering office in 2022 (although the portfolio was abolished with this year’s reshuffle). Upon taking the role, assistant minister Matt Thistlethwaite suggested the “twilight of [Queen Elizabeth’s] reign” presented “a good opportunity for a serious discussion about what comes next for Australia”.

Charles doesn’t seem to be taking all this too personally. In a letter responding to the Australian Republican Movement in March this year, his private secretary said the king viewed this as “a matter for the Australian public to decide”.

The royal tour and the meeting in Samoa will be important opportunities for the monarchy to connect with Australia and other Commonwealth nations.

By presenting itself as a modern institution engaged with contemporary issues such as climate change, the monarchy will also have to engage with the possibility of new political identities for its former colonies.

Politics with Michelle Grattan: ‘It’s going to be a bad result for Labor’ – Antony Green and Michael McKenna on the Qld election

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Queenslanders vote on October 26 when, according to the polls, the almost decade-long Labor government is expected to be defeated.

Last year, in a bid to improve its chances, Labor dumped long-time premier Annastacia Palaszczuk in favour of Steven Miles.

Miles has handed out or promised extensive and expensive cost-of-living support, including $1000 rebates on electricity bills, 50-cent fares, and now promising free school lunches.

But even all this seems to have failed to drastically change the mood in the electorate.

To discuss what’s happening on the ground, the potential outcome and what that could mean for the federal Labor government, we’re joined by the ABC’s election specialist, Antony Green and The Australian’s Queensland editor, Michael McKenna.

Green says:

The swing has shifted from being catastrophic to just being very bad.[…] the odds are the government’s going to lose.

All the government’s marginal seats are in the regions, in the regional cities in the north of the state. If it’s a 5 or 6% swing uniform, then all those regional city seats will be knocked out. And once they’ve lost a couple of seats in Brisbane’s belt as well, they’re out of government. So they’re in a very difficult position.

On what a poor result for the Labor party could mean federally, Green says:

Labor won the last federal election without doing well in Queensland – [there] was always a view that they couldn’t win an election without doing well in Queensland. They did well in WA instead. Can Labor do worse in Queensland at the next federal election? Well that’s a tough ask, it’s hard to see how. You would have to be back to the level of the defeat of the Whitlam government or the Keating government to do worse in Queensland, and I’m not sure that it’s that level of disaster for the Labor Party. I think there will be a lot of comment on that. But I mean this is a Queensland election and it’s fought on and very much based around sort of Queensland issues.

Michael McKenna says of the general mood:

I think for the first time in a few years, I’m seeing a real mood for change in government. Labor is seeking a fourth term on the trot. You can see it in the published polling, which for about the last two years has shown that Labor’s support is sliding and the Liberal National Party has the momentum. I think there’s a real ‘it’s time’ factor.

What we’ve seen is that Labor’s brand is still seemingly on the nose, particularly in the regions. And Steven Miles, […] he’s given a red hot go, but so far, I’m not seeing much evidence that he’s going to pull out a miracle win.

McKenna highlights Opposition Leader David Crisafulli’s strategy:

There’s no doubt that he has adopted a small target strategy to, in one way, focus people’s attention on the failings of a government which has a record of ten years, and there’s always going to be failings and things that are going to make people angry. But I would say that this is arguably the smallest of small target strategies that we’ve ever seen.

David Crisafulli really only wants to talk […] about the issues that he wants to talk about, and those are crime, particularly youth crime, cost of living, housing and health. But he doesn’t like to be pushed onto any other issues, and he’s done a good job in one sense in that he’s probably the most disciplined conservative party leader I’ve seen in decades in Queensland.

Claims that Qantas is greenwashing build a case for carbon assurance: here’s what it is

Source: The Conversation (Au and NZ) – By Md Safiullah (Safi), Senior Lecturer in Finance, RMIT University

Qantas is being taken to Australia’s consumer regulator over its claim it is committed to achieving net zero emissions by 2050.

The Environmental Defenders Office and the advocacy group Climate Integrity say the claim is “not backed up by credible targets or substantiating strategies” making it potentially misleading and in breach of the Australian Consumer Law.

The Australian Competition and Consumer Commission has yet to decide whether to investigate the complaint, and Qantas has yet to respond.

The complaint follows a ruling by a Dutch Court earlier this year that the airline KLM had misled consumers by creating the false impression it was sustainable.

The win has spurred the European Commission to write to 20 airlines identifying potentially misleading claims and inviting them to bring their practices in line.

Of most concern to the European regulators are claims the carbon emissions caused by flights can be offset by climate projects and the use of sustainable fuels, to which the consumers can contribute by paying additional fees.

Carbon assurance assesses claims ahead of time

These kinds of complaints would be much easier for airlines (and other compnies) to deal with if they had submitted themselves to a process known as carbon assurance ahead of time.

Usually entered into voluntarily, and conducted by an independent assessor in accordance with an international standard, the process verifies the accuracy, transparency, and credibility of an organisation’s carbon emissions claims.

My own research with Linh Nguyen, just published in Finance Research Letters, finds firms with high carbon assurance scores are more likely to obtain more trade credit from their suppliers.

Europe and Australia are moving towards making carbon assurance mandatory for large corporations.

Few firms submit themselves to it

A survey by KPMG International finds that while nearly all of the world’s 250 largest firms report on the sustainability of their operations, only two-thirds submit themselves to carbon assurance.

Another survey of 5,183 companies from 42 countries that publish emissions data finds half don’t engage a carbon assuror.

This could be because they are afraid of what the assuror will find.

An international survey of 750 companies that sought some level of external assurance found just 14% received a reasonable assurance.

Many firms aren’t ready

Assessors are hard to find.

Assurors, and the skills within the organisation to handle the process are hard to find. While international standards are in place, there isn’t yet a professional or regulatory body to certify assurors.

The Australian government intends to make assurance reports for the
Scope 1 and Scope 2 emissions of large firms mandatory from July 2026.

Scope 1 and scope 2 emissions are the direct and indirect emissions of the corporation itself.

The government intends to make Scope 3 emissions (those in other parts of the corporation’s supply and distribution chain) mandatory from July 2030.

It will be important to get the systems in place.

While what the firms report will matter a lot, what will matter almost as much is an assurance we can believe what they report.

Mysterious black balls have washed up on Sydney’s Coogee beach. Are they the result of an oil spill, or something else?

Source: The Conversation (Au and NZ) – By Sharon Hook, Principal Research Scientist, CSIRO

Sydney’s popular Coogee beach has been closed until further notice after hundreds of strange black balls washed up on the shoreline.

here
The black balls were discovered on Tuesday afternoon.
Randwick City Council

The balls were discovered on Tuesday afternoon. The local authority, Randwick City Council, says samples have been collected for testing, and the incident has been reported to the Environment Protection Authority and Beachwatch NSW.

A council spokesperson said the debris may be “tar balls” formed when oil comes into contact with debris and water – typically the result of oil spills or seepage.

I am a senior research scientist at CSIRO, specialising in environmental toxicity. While the objects could be tar balls, in my view, it is also possible they are something else. But in any case, the debris poses a potential risk to marine life and the public, and authorities were right to close the beach.

What are tar balls?

Tar balls are typically dark, sticky blobs found on beaches after an oil spill. They occur when oil comes into contact with the ocean’s surface and becomes weathered by wind and waves. This breaks the oil patches into smaller pieces.

Tar balls usually form in a variety of shapes and sizes – ranging from big, flat pancakes to tiny spheres. The image below shows a typically irregular tar ball that washed up on an island in the United States.

Tarballs, such as this one found on Dauphin Island, Alabama, usually form in a variety of shapes and sizes.
NOAA

On this basis, I am not certain the pieces of debris found at Coogee are tar balls. They certainly might be. I haven’t seen them in person, but from the publicly available images, the objects appear to be relatively uniform, perfectly round shapes. That would be very unusual for tar balls – but not impossible.

The balls could be plastic debris washed off a container ship, such as squash balls or plastic used in manufacturing. But obviously, we have to wait until tests have been conducted on the objects before we can determine their origin and composition.

And finally, the balls appear to have washed up only at Coogee beach. It would be uncommon for oil spill remnants to drift to a single location unless the spill happened very close to shore.

What are the potential harms?

Whatever the objects are, they could pose a hazard to marine life.

If the objects are sticky or oily, they may coat animals that come into contact with them. An animal that ate the objects may also be harmed. The balls would be difficult to digest and might stay in the animal’s stomach for a long time, preventing it from eating other food.

If the objects are in fact tar balls, this is dangerous to animals because oil can be carcinogenic.

What should be done?

Every precaution should be taken until we know exactly what these mysterious objects are.

Authorities are doing the right thing in keeping people away from the beach as the cleanup and testing continue. The public should heed official advice not to enter the beach and especially, not to touch the spheres.

At this stage, it appears no other beach is affected, so there are plenty of other nearby options for beach-lovers.

In the meantime, we should let the forensic scientists and other experts do their job.

Social media footage reveals little-known ‘surfing’ whales in Australian waters

Source: The Conversation (Au and NZ) – By Vanessa Pirotta, Postdoctoral Researcher and Wildlife Scientist, Macquarie University

Sapphire Coastal Adventures

As humpback and southern right whales return to Antarctica at the tail end of their annual migration, east coast whale watchers may think the show will soon be over. But some whale species are still here, possibly year-round. And we need to find out more about them.

My team’s new research concerns one of these little-known species – the Bryde’s whale. You may have seen it feeding, breaching or surfing, without realising what it was.

My colleagues and I wanted to learn more about where Bryde’s whales can be found in Australian waters. So we tapped into observations shared on social media, including drone footage and photographs from whale-watching tours. We also gathered observations from scientists.

We discovered a wealth of information. It includes evidence of feeding and “surfing” behaviours possibly never documented before. Findings from this research will directly help inform conservation efforts to protect this species, which we still know so little about in Australian waters.

Observing whales through citizen science

Scientists can’t always be out in the field, or on the water. That’s why the data gathered by everyday people, known as “citizen scientists”, can be so useful. It captures valuable information about wildlife that can be used later by professional researchers.

Citizen science projects involving marine life have grown over recent years. They include people documenting humpback whale recovery by counting northward migrating humpback whales off Sydney, and people watching sharks off Bondi Beach via the @DroneSharkApp.

Hungry hungry whales

Like humpback whales, these giants are “baleen” whales, meaning they are toothless. But Bryde’s whales have a much pointier mouth and lack that famous hump.

A preference for warmer waters means Bryde’s whales are also known as tropical whales. They can be found in tropical or subtropical waters.

Around the world, Bryde’s whales have demonstrated interesting feeding behaviours, from high-speed seafloor chases to “pirouette feeding”.

Hanging out in shallow and deep waters

Our study documented Bryde’s whales feeding in both deep and shallow waters off the east coast of Australia, alone or sometimes with other whales.

We tapped into more than an hour of drone vision and more than 200 photos of Bryde’s whales shared by citizen scientists on social media platforms such as Facebook, Instagram and YouTube.

In offshore environments, Bryde’s whales were typically seen “side lunging” – where they propel themselves forward and turn onto their side then open their mouth to engulf their food. They also swam from below and scooped up their prey, much like humpback whales.

Brett Dixon

In shallow waters, Bryde’s whales were observed feeding directly within or behind the surf break.

We believe this is a new feeding behaviour for this species. We call it “shallow water surf feeding”.

Whales may be using the surf to assist with their feeding efforts, or, perhaps they are there because that’s where the bait fish are hanging out.

Regardless, it’s impressive to see such a large whale in the surf and in shallow waters.

Spotted: mums with their calves

We also documented mothers with calves. This indicates some parts of the Australian east coast could possibly serve as an important area for nursing mothers with their young. They could also be using these waters for calving.

We don’t yet fully understand the species’ movements around Australia, and whether they swim in New Zealand waters. For example, the world-famous white humpback whale Migaloo has been known to swim across the Tasman Sea.

Brett Dixon

Could these Bryde’s whales we see here in Australian waters be the same ones seen in New Zealand waters? Are they calving in New Zealand or Australia and moving between the two? If so, what does this mean for their protection?

Whales don’t recognise international boundaries. They go where they want, when they want. This is why collaborative research like this is important for our growing knowledge of this species.

The more we know, the better we can protect

This is the first dedicated paper on both the occurrence and feeding behaviour of Bryde’s whale in Australian waters.

As humans continue to expand our footprint in the ocean through activities such as offshore wind energy, shipping, fishing and tourism, knowledge of this species and others can help inform future decisions in our blue backyard.

Findings of this study will directly contribute to Australia’s efforts to protect whales. One immediate action will be contributing information to the federal review of Biological Important Areas for protected marine species. The more we know, the better we can target conservation efforts to provide for a species we know relatively little about in Australian waters.

And even though the humpbacks and southern rights are headed back south to Antarctica for the summer, it’s still worth keeping your eyes on the water. You might be the next person to spot a Bryde’s whale in Australian waters. Let us know if you do!

The government has a target for Indigenous digital inclusion. It’s got little hope of meeting it

Source: The Conversation (Au and NZ) – By Bronwyn Carlson, Professor, Critical Indigenous Studies and Director of The Centre for Global Indigenous Futures, Macquarie University

Digital inclusion for Indigenous communities is important. It’s so important, in fact, that the government has made it one of the targets under the Closing The Gap plan. The goal is:

by 2026, Aboriginal and Torres Strait Islander people have equal levels of digital inclusion.

Digital exclusion is the continuing unequal access and capacity to use digital technology that is essential to participate fully in society.

It severely stifles Indigenous creativity. It restricts access to essential tools, skills and platforms that are crucial for digital expression and innovation.

For many Aboriginal and Torres Strait Islander peoples, this exclusion leads to missed opportunities, particularly in areas linked to economic prosperity, such as employment and education. As the government’s policy focus is on economic empowerment, this is a major barrier.

Measuring progress towards the 2026 deadline is challenging because there are simply no recent data.

But given how big the gap was to start with, the lack of importance based on gathering relevant data and the insufficient government action since, we know the target is highly unlikely to be met.

‘Digital inclusion’ and closing the gap: how First Nations leadership is key to getting remote communities online


What’s being done?

To support the goal, the First Nations Digital Inclusion Plan offers a comprehensive strategy focused on three key pillars:

  • access (to telecommunication services, devices, and data)

  • affordability (the cost of services, devices, and data)

  • ability (skills, attitudes, and confidence with technology).

Focused mostly on remote communities, initiatives such as the Australian Digital Inclusion Index highlight persistent challenges across all three areas.

Although digital inclusion is an urgent issue in remote areas, research also shows Indigenous populations face widespread digital exclusion across the nation, regardless of remoteness.

Some 84.6% (832,800) of Indigenous people live in non-remote areas. Many of these people are also excluded.

Last year, the government established an advisory group to drive progress.

It has developed a “road map”. This involves travelling to Indigenous communities across Australia to ensure their diverse needs, aspirations and environments are fully considered.

Despite these ongoing government initiatives and policies, efforts to close the digital divide for Indigenous peoples remain insufficient. As technology continues to advance, Indigenous communities are left in an increasingly precarious situation.

The rise of artificial intelligence

The government’s current plans do not explicitly address the role of artificial intelligence (AI). This oversight is particularly concerning given the rapid advancement of AI technologies.

A recent report on adult media literacy in Australia reveals 48% of Aboriginal and Torres Strait Islander participants do not understand what AI is or the risks and opportunities it presents. This knowledge gap could further exacerbate the digital divide and deepen existing inequalities.

AI presents both opportunities and challenges. When led by Indigenous people, it holds transformative potential across multiple sectors.

It could enhance learning tailored to Indigenous knowledge systems, help in the revitalisation and preservation of languages, and improve healthcare delivery. It could also empower Indigenous businesses by optimising operations and market reach.

AI affects everyone – including Indigenous people. It’s time we have a say in how it’s built


Indigenous people are already collaborating on research that combines Indigenous knowledge with AI to support land-management practices.

There are very few Indigenous-led AI projects underway nationally, but there’s great potential. With Indigenous people helping develop AI, these technologies could contribute to meaningful, self-determined growth across Indigenous communities.

But only if we’re included.

Avoiding exploitation

Indigenous digital exclusion, especially in policy development and regulation, can result in AI being used by non-Indigenous people to tell our stories without our permission.

They can profit from appropriation of our culture, including art and languages.

The government needs to adopt a more comprehensive and forward-thinking approach. This should involve expanding the scope of digital inclusion initiatives beyond the current limited focus to encompass Indigenous communities across the entire country.

The development of Indigenous-led digital literacy programs that respect learning styles and culture is also essential.

The government should incorporate AI and other emerging technologies into planning to ensure Indigenous communities are not left behind.

Establishing long-term partnerships with technology companies, educational institutions and Indigenous organisations to create sustainable digital inclusion programs is vital.

The focus should be on creating Indigenous-led opportunities that leverage digital technologies for economic empowerment without exploiting or harming.

Underrepresented in tech

One barrier to this is there are very few Indigenous peoples involved in the tech industry, especially in decision-making roles and policy development.

As of 2022, Aboriginal and Torres Strait Islander people accounted for less than 1.4% of tech workers. There urgently needs to be more support to boost this figure.

That’s because technology like AI presents potential careers for Indigenous people.

Currently however, Indigenous peoples are not employed in the industries involved in AI. Of the global study of people working in this specific industry, Indigenous participation was not noted.

The fact the government recognises digital inclusion as a national priority is a positive step. The current approach, however, is piecemeal and limited. We need a more holistic strategy.

By developing more inclusive, technologically advanced policies led by Indigenous people, the government can ensure they are not left behind in the digital age. We need to be at the decision-making table.

Closing the digital divide requires a multifaceted, long-term commitment from government. This means a national strategy recognising the diverse needs and aspirations of Indigenous communities across the country.

By harnessing the full potential of digital technologies, including AI, and addressing the unique challenges faced by Aboriginal and Torres Strait Islander people, the government can create lasting positive change and truly empower Indigenous communities in the digital era.

Should King Charles apologise for the genocide of First Nations people when he visits Australia?

Source: The Conversation (Au and NZ) – By Rebe Taylor, Associate Professor of History, University of Tasmania

King Charles and Queen Camilla will visit Australia from Friday on a five-day tour of Canberra and Sydney.

The king will be the second ruling British monarch to visit Australia, after Queen Elizabeth II’s 16 visits over 57 years.

These visits showcase Australians’ evolving relationship with the monarchy and our colonial past.

Changing attitudes

An estimated 75% of Australians greeted Elizabeth on her first tour in 1954, at events that celebrated Australia’s growth as a prosperous nation.

Historical milestones remained central to the queen’s subsequent visits.

In 1970, she attended the re-enactment of Captain Cook’s arrival at Botany Bay. This included depictions of shooting at First Nations actors.

The queen’s 1986 visit included signing the Australia Act that severed Britain’s formal powers over Australia.

Her 1988 visit coincided with the Australian bicentenary of the arrival of the First Fleet carrying convicts and officials from Britain. But by this time, many Australians had lost their royal fervour.

Her final tour, in 2011, came 12 years after Australia had attempted to become a republic by referendum.

The queen’s death in 2022 not only reignited questions over the future of the monarchy in Australia, it instigated a public discussion over the monarchy’s role in imperial colonialism.

Genocide in Australia?

On the eve of Charles’ coronation in 2023, Indigenous leaders from 12 settler states including Australia and New Zealand cosigned a letter calling on the new monarch to apologise for the genocides that British colonisation brought to their territories.

Australia was settled in the name of the Kingdom of Great Britain. Did that settlement result in genocide?

Recent research led by Ben Kiernan for The Cambridge World History of Genocide has investigated this question using the 1948 United Nations Convention on the Prevention and Punishment of the Crime of Genocide as a framework.

The convention defines genocide as “acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group”.

The term “genocide” itself is modern; coined by Raphael Lemkin in 1944. The colonisation of Tasmania by the British provided Lemkin with one of the clearest examples.

The prosecution of crimes before 1951 is not permissible under the convention, which provides a definitional framework to evaluate past events as constituent acts of genocide.

The Cambridge World History of Genocide Volume II and Volume III demonstrate how settlers and government agents committed acts of genocide against First Nations Australians from the beginning of settlement to the late 20th centuries.

All parts of Australia are considered. Acts conforming to the convention’s clauses include killing, forcibly removing children and inflicting destructive conditions.

Australian historian Lyndall Ryan’s chapter, Frontier Massacres in Australia, draws on her research for a Massacre Map showing how British troops and settlers committed more than 290 massacres across Australia between 1794 and 1928.

These massacres killed more than 7,500 Aboriginal people.

Ryan found the massacres were not sporadic and isolated – they were planned and sanctioned killings, integral to the aims of the Australian colonial project.

Rebe Taylor’s chapter on genocide in Tasmania details a pattern of government-sanctioned mass killings in a colony where an estimated 6,000 Palawa (Tasmanian Aboriginal) people were reduced to about 120 by 1835.

Raymond Evans shows how as colonisation moved northward in Australia, massacres increased in size.

Evans documents killings that persisted into the 1940s, postdating the 1928 Coniston massacre widely regarded as the last frontier slaughter.

These findings are underscored by Tony Barta’s insight that colonists’ destructive actions constitute a record of genocidal intent “more powerful than any documented plot to destroy a people”.

Research by Anna Haebich documents the taking of Indigenous children during the 19th century.

Joanna Cruikshank and Crystal Mckinnon explain how these state-sanctioned removals in the 20th century were intended to eliminate First Nations people from Australia’s national life.

The 1997 Bringing Them Home report, commissioned by the Human Rights and Equal Opportunity Commission, concluded the “Australian practice of Indigenous child removal involved […] genocide as defined by international law”.

A significant moment of resistance

The colonial governor of Tasmania began to exile Palawa people from their land in 1829.

More than 200 survivors of the “Black War” were removed to Flinders Island and subjected to life-threateningly harsh conditions. High death rates were caused by ill-treatment, disease and insufficient care.

In 1846, the Palawa petitioned Queen Victoria to honour the agreement made when they were removed: that in exchange for temporarily leaving their country, they would regain their freedom.

In this bold petition, Tasmanian Aboriginal people initiated a historic appeal to the British monarchy.

Aware of Queen Victoria’s sovereign authority across the vast British Empire, this action marked a significant moment in their continued resistance to genocide.

An acknowledgement of wrongs

British sovereignty over Australia was imposed without the required consent of its First Nations. The result has been continued dispossession and suffering.

Despite the Crown’s deferral of power to its parliament, the call for an apology from the king has immense symbolic importance.

It is rooted in the desire for acknowledgement of wrongs. These include genocide and the continuing destructive effects of colonisation across Australia.

Mounjaro is more effective for weight loss than Ozempic. So how does it work? And why does it cost so much?

Source: The Conversation (Au and NZ) – By Paul Joyce, Senior Research Fellow, University of South Australia

Halfpoint/Shutterstock

A weight-loss drug more effective than Ozempic and Wegovy has recently been approved in Australia.

The drug, tirzepatide, is sold under the brand name Mounjaro and affects feelings of hunger and fullness, as well as changing how the body processess food. (In other countries, tirzepatide is also sound under the brand name Zepbound.)

So how does tirzepatide work and differ from Ozempic? And with a price tage of $315–$645 per month for the starting dose, why is it so expensive?

How does it work?

Think of tirzepatide as a master key that unlocks two important doors in your body’s weight control system. It mimics two hormones: GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide).

When you eat, your body naturally releases GIP and GLP-1 hormones. These hormones play crucial roles in regulating appetite, food intake and blood sugar levels. Tirzepatide mimics and amplifies the effects of these hormones.

By mimicking the GLP-1 and GIP hormones, tirzepatide makes people feel fuller with smaller meals. This can reduce the overall food intake and lead to weight loss over time.

It also helps your body process sugar more effectively and slows down how quickly food leaves your stomach. This results in eating less, feel satisfied for longer and having healthier blood sugar levels.

How does it compare with Wegovy/Ozempic?

Tirzepatide (Mounjaro) and semaglutide (Wegovy/Ozempic) are similar in many ways. Both are injectable medications used for weight loss and work by mimicking hormones that regulate appetite and blood sugar.

The key difference is that tirzepatide acts on two hormone receptors (GIP and GLP-1), while semaglutide only acts on one (GLP-1). This dual action is thought to be why tirzepatide shows slightly better results for weight loss in clinical trials.

Clinical trials have shown participants lost an average of 25% of their body fat in the first year of treatment with tirzepatide. This is when combined with lifestyle counselling from a health-care professional who encouraged a healthy and reduced-calorie diet (500 calories less per day compared to patient’s diet at the beginning of the study) and at least 150 minutes of physical activity per day.

This compares with an average of 15% weight loss in the first year for semaglutide, also alongside a reduced-calorie diet (a 500 calorie-deficit per day) and increased physical exercise (150 minutes per week).

For a person weighing 120kg, this might mean the difference between losing 30kg with tirzepatide versus 18kg with semaglutide. But of course, with both drugs, some people will lose less weight than the average, some will lose more, and some may not respond to the drug at all.

What are the side effects of tirzepatide?

Like any medication, tirzepatide has side effects. The most common are nausea, vomiting, diarrhoea and constipation. These could feel like a mild tummy bug and are similar to those seen with semaglutide.

For most people, these side effects are manageable and often improve over time.

There are also some rarer, more serious risks to consider. These include inflammation of the pancreas and gallbladder problems. There is also a potential increased risk for thyroid cancer, although this has only been seen in lab rats so far, not humans.

As with Ozempic and Wegovy, when you stop taking tirzepatide, its effects stop. Most people regain some, if not all, of the weight they lost.

Who can access tirzepatide?

In Australia, tirzepatide is approved for use in adults with a body mass index (BMI) of 30 or higher, or a or BMI of 27 or above if you have a weight-related health condition such as diabetes. It can only be prescribed by a doctor, after you have tried other weight-loss methods.

But it’s not suitable for everyone. It shouldn’t be used in pregnancy and may not be suitable for people with certain medical conditions and those with a history of eating disorders.

If you’re considering tirzepatide, it’s important to discuss the benefits and risks for your personal health situation with your doctor.

Why is it so expensive?

Tirzepatide typically costs around A$345 per month for the starting dose. This can escalate to $645 per month for the ongoing “maintenance” dose if a higher dose is necessary for diabetes and/or weight management. This puts the drug out of reach for most people.

Tirzepatide, sold as Mounjaro in Australia, is only available on private prescription and is not subsidised by the Pharmaceutical Benefits Scheme (PBS). This means you pay the full cost of the medication without any government support.

However, the United Kingdom recently announced it would add tirzepatide to the National Health Service in a phased approach over the next three years, so it’s possible we might see it subsidised in Australia in the future.

Developing new drugs is a costly business. Companies spend billions on research, clinical trials, and getting regulatory approvals. They then set high prices to recoup these costs and make a profit.

The patent for tirzepatide lasts until 2036. So we won’t have any cheaper generic versions for more than a decade.

Glucose monitors for diabetes have finally been funded – but a chronic workforce shortage will limit the benefits

Source: The Conversation (Au and NZ) – By Lynne Chepulis, Associate Professor, Health Sciences, University of Waikato

Pharmac’s decision to fund continuous glucose monitors and automated insulin delivery systems for the approximately 18,000 people who currently live with type 1 diabetes in Aotearoa New Zealand is good news.

The decision comes after years of advocacy from patient groups and clinicians.

But there are problems within the broader system – particularly around workforce shortages – that mean full patient access to training on how to use the insulin pumps will likely take years.

Failing to address these issues will also perpetuate health inequities for Māori and Pacific people, who are less likely to have used the monitor and pump in the past, and may have to wait longer for training. These delays could mute the positive effect of Pharmac’s funding decision.

A complex balance

Type 1 diabetes is an autoimmune disorder that causes a person’s pancreas to stop producing insulin. This all-important hormone is needed to move glucose into every cell in the body.

Without insulin, the cells (and the person) “starve”. While the current approach to the management of type 1 diabetes – finger pricking to test blood glucose levels and injecting insulin – works, it’s complex.

Inject too much insulin and you’ll get low blood sugar (hypoglycaemia). This leaves a person with type 1 feeling shaky and weak, or possibly even in a coma. Don’t inject enough and you have ongoing high blood sugar (hyperglycaemia). This leads to long-term health complications.

Figuring out the right amount of insulin is elusive. Needs constantly vary according to time of day, diet, exercise, illness, caffeine, alcohol, stress and other factors. This can take a toll psychologically and physiologically.

Modern solutions

Continuous monitors track blood glucose levels 24 hours a day through a sensor just under your skin, replacing finger-prick testing. They are widely funded and used overseas.

The monitors alert users to low blood glucose and have significantly reduced hospitalisations for people with type 1 diabetes.

Combining the monitors with a pump and appropriate algorithm automates the delivery of insulin when glucose levels rise higher than a patient’s target range – significantly reducing the day-to-day burden of treatment.

But the continuous monitors and insulin pumps are expensive.

Prior to Pharmac’s decision, the monitors were completely unfunded. Prices ranged between NZ$2,600 and $4,800 per year. Insulin pumps were funded, but only for a small group of people.

This created an ever-widening equity gap. Māori and Pacific people with type 1 diabetes were less likely to access monitors and pumps. They were also more likely to have recurrent hospitalisations for diabetes-related events.

A workforce shortage

When compared with other countries, New Zealand has been slow to fund the monitors.

Unfortunately, the diabetes workforce is also significantly understaffed when compared to international guidelines.

There is a shortage of all qualified health care professionals for type 1 diabetes including endocrinologists, nurse practitioners, diabetes nurse specialists, dietitians, psychologists, social workers and podiatrists.

To meet international recommendations, New Zealand would have to more than double the clinical workforce.

Most people with type 1 diabetes will be able to rapidly access the monitors because these can be prescribed through GPs as well as by diabetes specialists. However, insulin pumps and automated insulin delivery will only be accessible through specialists.

While insulin pumps offer advantages for managing glucose levels, learning to use the device takes time and requires support from clinicians. This will likely be a problem, particularly for those who already have challenges accessing healthcare services in this country.

An equity issue

Māori and Pacific people with type 1 diabetes are less likely to be current insulin pump users. This means there is a clear risk of workforce shortages causing those who would benefit most from automated insulin delivery to be among the last to have access.

Increasingly, evidence on continuous glucose monitors and automated insulin delivery shows they improve managing type 1 diabetes for everyone.

Monitor use has been shown to reduce the differences in the management of glucose levels between Māori and non-Māori children with type 1 diabetes.

Automated insulin delivery can also be an effective tool for children and adolescents with very high-risk glucose levels.

So, thank you Pharmac. Funded devices are a game changer. New Zealand has moved from an outdated, inequitable system of technology funding in type 1 diabetes to a progressive and fair system. But so much more needs to be done to support everyone with this disease.

Overtly handmade and so very moving: Adam Elliot’s Memoir of A Snail is a stop motion triumph

Source: The Conversation (Au and NZ) – By Jack McGrath, Lecturer in Animation at the University of Newcastle, University of Newcastle

Many iconic Melbourne sights, including Luna Park, feature in Adam Elliot’s new film. Madmad Entertainment

Stop motion films are by their nature a remarkable feat. When you know a movie has been carefully crafted, over several years and through thousands of photographs of handmade sets and characters, this alone makes it a delight to watch.

But when the story is also deep, thought-provoking and at times laugh-out-loud funny, this takes the medium to a whole new level. Adam Elliot’s Memoir of a Snail is such a film.

Told through stop motion animation using clay (otherwise known as claymation), the film is a tactile experience in which everything you see has been made by human hands. This provides a warmth that is exacerbated by Elliot’s very human story of identity.

The film explores how it can be difficult to find your way in life, particularly when you’re different – and that it is, in fact, OK to be different.

Grace Pudel, the protagonist, is a snail enthusiast and we follow her as she navigates the many challenges that emerge in her life. Grace’s narration is raw and honest, and we can’t help but feel a deep connection with her.

The story is so human and so very moving – and to be told through human-made characters perfectly rounds off the experience.

Grace is a hoarder of ornamental snails, romance novels and guinea pigs.
Madman Entertainment

A win at Annecy

In June, I was fortunate enough to help facilitate an animation study tour in France with students from the University of Newcastle. It was there we saw the world premiere of Memoir of a Snail at the Annecy International Animation Film Festival, the pre-eminent festival for animated film.

The story clearly resonated with the audience, who sat captivated throughout its 90-minute runtime. They laughed and cried in unison as one engaged mass of humanity – culminating in a long and enthusiastic standing ovation.

We were even lucky enough to bump into Elliot and his crew, and our students spoke with him about his journey in making Memoir of a Snail. The film went on to win the festival’s prestigious Cristal award for best feature.

More than 7,000 individual items were handcrafted by various artisans, with most objects made from clay, wire, paper, paint and silicon.
Madman Entertainment

While claymation is generally viewed as a medium aimed at young audiences, Memoir of a Snail tells a wholly unique adult story.

Much of its sophistication lies in its ability to effortlessly touch on many complex topics through a mixture of humour and emotion. Indeed, this approach to storytelling has become Elliot’s calling card.

The film’s themes include identity, loneliness, alcoholism, cultism, hoarding, suicide, homosexuality, bullying, ageing, family, fat fetishism, grief and death. The story cleverly pulls you into deep thought, before surprising you with a hilarious gag.

Grace (voiced by Sarah Snook) strikes up friendship with an eccentric elderly woman named Pinky (Jacki Weaver).

Elliot’s dark and captivating aesthetic

When introducing the film at Annecy, Elliot explained how his team’s limited budget led to a heavy reliance on narration, with limited walking and dialogue shots. Yet these constraints seemed to enhance the team’s creativity rather than stifle it.

Elliot has a history of working around such limitations to bring his unique aesthetic to life. His first film Uncle (1996) was shot on 16mm black-and-white film, while his other short Cousin (1999) was shot on colour – but with a muted palette of grey tones.

This palette has carried through Elliot’s work and is present in Memoir of a Snail. His version of the Australian landscape isn’t orange and sun-bleached. Rather, it is grey, overcast and drab – a dark world resembling the work of Eastern European animators such as Jan Švankmajer.

Elliot’s other films include Brother (2000), the Oscar-winning short film Harvie Krumpet (2003) and his first feature film Mary and Max (2009).

His works present tortured individuals – outsiders, misfits and oddballs – living in dark, suburban worlds. Behind the funny-looking faces and humorous vignettes lie deeper afflictions that become clear as the characters struggle through their lives.

More than 1,000 plasticine mouths had to be made so the characters could talk.
Madman Entertainment

A gentle vulnerability shines through

Elliot brings a naivety to the narration, where a simple statement of facts couches a deeper meaning. As the audience, we uncover mixed feelings of humour, dread and empathy for the tortured blobs of clay before us.

The characters stand, blinking, looking back at us while the narrator describes their situation. They feel vulnerable, as though asking for our help as they stand silently, trapped in Elliot’s bleak world.

Grace falls into dark spiral after she is seperated from her twin brother Gilbert (Kodi Smit-McPhee) at a young age).
Madman Entertainment

Memoir of a Snail maintains a strong sense of materiality, as evidenced by fingerprints left on clay and brush strokes on painted backgrounds. Elliot’s self-described “chunky wonky” aesthetic abides by the rule that nothing in the world is straight.

Almost everything in Elliot’s animated world is overtly handmade, presenting a kind of nostalgic and childlike innocence you’d expect from a school project. This helps add weight and authenticity to the film.

The 3D work intersects with thoughtfully crafted 2D items such as handwritten title cards and signs.
Madman Entertainment

Elliot’s world is created “in-camera”, which means no digital effects were used. Water, for example, was created using cellophane, while droplets were painstakingly animated with blobs of glycerine, one frame at a time.

Welcome relief in a hyper-digital world

Lately, Australian animation has found an international audience and this has emboldened Australian animators to tell Australian stories. Bluey, for instance, has struck a chord with viewers globally because of – and not despite – its uniquely Australian voice.

It took eight years to create Memoir of a Snail, which seems like a lifetime in today’s world. Witnessing such dedication may inspire audiences to think more deeply about animation as an art form and about film-making itself.

Elliot’s handmade style is a nice counter to the digital and visual effects that seem ever-present in media today.
Madman Entertainment

Memoir of a Snail is a testament to stop motion’s power to move people. Elliot himself pointed out how stop motion seems to be experiencing a renaissance, with Guillermo Del Toro’s Pinocchio (2022), Phil Tippett’s Mad God (2021), Henry Selick’s Wendell & Wild (2022) and Chris Butler’s Missing Link (2019) all serving as recent examples of stop motion features.

I hope Memoir of a Snail helps sustain this interest. In an age of automation and artificial intelligence, the film is a welcome return to the human experience. Thought-provoking, funny and wholly unique in its story and visual style, it’s well worth the watch.

Other voice actors on the production include Eric Bana, Nick Cave and Tony Armstrong.

Why China now wants to put some limits on its ‘no limits’ friendship with Russia

Source: The Conversation (Au and NZ) – By Guangyi Pan, Teaching fellow, international politics, UNSW Sydney

Just before Russia’s invasion of Ukraine, China announced to much fanfare a “no-limits friendship” with Russia, suggesting a future of close collaboration in trade, energy and, perhaps most importantly, security.

Now, more than two years into the war, the meaning and interpretation of this “no-limits” commitment has evolved.

There has been much debate in Chinese society in recent months about Beijing’s alignment with Moscow. While some have advocated for a more formal alliance with Russia, others have taken a more cautious stance.

In sharp contrast to 2022, China’s growing wariness is increasingly being discussed in the open, even among those who were previously censored. In early 2022, for instance, a joint letter by six Chinese emeritus historians opposing Russia’s invasion was censored by the government. The scholars were also warned.

Now, however, it appears the government is seeking to balance its relationships with both Russia and the West. Beijing may not want to be seen as a “decisive enabler” of the war.

For example, the once-prominent “no-limits” friendship language quietly vanished from a Sino-Russian joint statement in May.

And Beijing’s response to Russian President Vladimir Putin’s visit that month was notably subdued. Putin ingratiated himself with Xi, saying they were “as close as brothers”. Xi’s response was more perfunctory – he called Putin a “good friend and a good neighbour”.

Scholars are also articulating their concerns about China’s political and economic investments in Russia, both publicly and privately.

Shen Dingli, a leading scholar of Chinese security strategy at Fudan University in Shanghai, said China doesn’t want to be seen as collaborating with Russia against Ukraine or any other country.

He also quoted Fu Cong, China’s former ambassador to the European Union, who said last year the “no-limits” [friendship] is “nothing but rhetoric”.

And in August, after Putin referred to China as an “ally” during a visit to far-eastern Russia, Chinese scholars promptly sought to clarify this statement to prevent any misunderstanding China wants a formal alliance with Russia.

These statements carry weight. In many respects, leading Chinese scholars at the government-affiliated universities act as propagandists to convey and justify the government’s stance on issues. As a result, subtle shifts in their commentary provide insights into the strategic mindset in Beijing.

Why China is rethinking its ‘no-limits’ friendship?

There are three elements driving this re-evaluation of the Russia-China alignment.

First, there is growing scepticism of Russia’s state capacities. The mutiny by the Wagner Group last year and Ukraine’s recent incursion into Russia’s Kursk region have prompted critical reassessments in Beijing of Russia’s political stability and military preparedness, as well as the growing anti-war sentiment in Russia.

As Feng Yujun, director of Fudan University’s Russia and Central Asia Study Centre, argued, the Wagner rebellion was a reflection of Russia’s internal conflicts and domestic security challenges. He noted every time Russia has faced both internal and external crises in history, its regimes have become less stable.

More recently, Feng has been even bolder, predicting Russian defeat in Ukraine. He argued China should keep its distance from Moscow and resume a policy of “non-alignment, non-confrontation and non-partisanship”.

Second, China’s sluggish economy and its underwhelming trade with Russia have further exposed how dependent both countries are on the West.

While Russia-China trade reached a record US$240 billion (A$360 billion) in 2023, it has slowed so far this year, as Chinese financial institutions have sought to limit connections with Russia.

The relationship still heavily favours Beijing. Russia accounts for only 4% of China’s trade, while China accounts for nearly 22% of Russia’s trade.

Many Chinese experts are now warning against an over-dependence on Russia, instead calling for more cooperation with neighbouring countries. This echoes a recent concern Russia has been using its natural resources as a bargaining chip to extract greater benefits from China.

Russia’s value as a military ally

Finally, there are rising Chinese concerns its international outlook does not align with Russia’s.

Zhao Long, deputy director of the Shanghai Institute of International Relations, says there is an important difference in how they view the world:

Russia wants to destroy the current international system to build a new one. China wants to transform the current system by taking a more prominent place in it.

Shi Yinhong, a strategist at Renmin University in Beijing, has highlighted an unbridgeable gap preventing a stronger China-Russia alliance. He says there’s a deep mutual mistrust on regional security. Russia has never promised support for China in the event of a conflict over Taiwan, just as China has avoided involvement in the war in Ukraine.

As Russia’s war in Ukraine reaches a stalemate, its value as a military ally is increasingly being questioned in China.

Recently, Feng Yujun warned China risks being led by the nose by Russia, despite being the stronger economic partner. He says every time China has attempted an alliance with Russia in history, it has had negative consequences for China.

Consequently, it is crucial for China to maintain its long-term partnership with Russia without undermining its constructive relationship with the West.

Russia has arguably benefited from the current competition between the US and China, as it has sought to exploit the rivalry for its own benefit. But this has also led to uncertainty in the China-Russia relationship.

As another analyst, Ji Zhiye, argues, relying too heavily on Russia will leave China isolated and vulnerable. And this is not a position China wants to be in.

Jokowi was once seen as Indonesia’s ‘new hope’. Instead, he leaves a legacy of democratic backsliding

Source: The Conversation (Au and NZ) – By Edward Aspinall, Professor in Southeast Asian Politics, Australian National University

As Indonesia’s president Joko Widodo (Jokowi) prepares to leave office, Indonesia is still routinely lauded as one of Asia’s most important democracies. Jokowi was first elected, in 2014, on the promise of breaking with the old Jakarta elite and making government more responsive to ordinary people.

He was backed by many ardent supporters of Indonesia’s Reformasi movement. This movement had brought down the authoritarian leader, Suharto, in 1998 and pushed a transition to democracy in the years that followed.

But Jokowi has overseen a serious period of democratic backsliding.

Democratic decline

Under his watch, the Indonesian government has hobbled democratic control institutions. This includes Indonesia’s once-lauded Corruption Eradication Commission, abbreviated as KPK.

Security agencies such the army and the police have begun to resume a political role.

The government has banned major Islamic organisations.

Civil society groups speak of a dramatically narrowed civic space. They complain, for example, about the government’s increasing reliance on the Electronic Information and Transactions Law to prosecute critics of the government for defamation and its growing willingness to use violent means to respond to protests.

Jokowi’s opponents in the political elite are routinely investigated for corruption and other alleged wrongdoing.

In last February’s presidential election, there were widespread reports the police and other agencies were pressuring community leaders to mobilise the vote for Jokowi’s preferred candidate, Prabowo Subianto.

How and why does Jokowi leave this legacy?

How did a man who was once seen as a “new hope” for Indonesian democracy end up here?

The answer is part of a global story that has become broadly familiar in recent years.

These days, it is generally not unelected coup leaders who destroy democracy. Experiences like those of Thailand and Myanmar in recent years are, happily, no longer typical.

Instead, elected populist leaders hollow democracy out from within. They do so by hobbling institutions, such as anti-corruption commissions, which are meant to check executive power.

Jokowi has, in my view, followed this pattern.

Unlike many populists, Jokowi never peppered his early speeches with angry denunciations of his opponents as traitors. He never tried to whip up vitriol against vulnerable minorities.

Instead, he positioned himself as a leader who was uniquely able to understand and to embody the aspirations of ordinary people.

His trademark campaign method was known as blusukan. He would drop by unexpectedly at a marketplace, for example, to chat with ordinary people about prices and other everyday matters.

Jokowi has positioned himself as a man of the people.

A former mayor, he was interested in the nitty gritty of governance, such as how to improve transport services or upgrade parks. He was less interested in “abstract” notions like human rights.

The implications of this philosophy only became apparent after Jokowi was elected president.

He retained his belief in his own unique ability to understand the aspirations of ordinary citizens, which had been long neglected by elite politicians.

He maintained a single-minded focus on what ordinary Indonesians wanted – improved living standards and better social welfare. And he used polls to regularly monitor public opinion.

For Jokowi, maintaining popular support and satisfying public demands was the essence of democracy. He was not interested in institutions that place limits on governmental power, which are arguably just as important to a functioning democratic system.

For example, his government enacted legal amendments that significantly weakened the Corruption Eradication Commission (KPK).

Late last year, the Constitutional Court – headed by his brother-in-law – changed the the rules on candidate age limits to allow Jokowi’s son, Gibran Rakabuming Raka, to stand for the vice presidency. Many Indonesians viewed this as a transparent – and successful – attempt to manipulate a key control institution for the purpose of maintaining Jokowi’s dynastic grip on power.

Even so, as Jokowi leaves office, he does so a very popular politician.

Prabowo as president

Jokowi hands power to a man with an even more chequered democratic history.

Prabowo Subianto is a former general with a record of alleged human rights abuses dating back to the late Suharto period. (Although, like other senior military officers accused of responsibility for the Suharto regime’s well-documented record of human rights abuses, he was never convicted of any crimes). Prabowo was close to the heart of that regime: indeed, he used to be Suharto’s son-in-law.

President-elect Prabowo Subianto speaks at a political rally.
Prabowo has promised he would provide the strong hand the country needed.
Algi Febri Sugita/Shutterstock

Prabowo has since reinvented himself as a fun-loving grandfather figure and Jokowi’s greatest fan, capitalising on the president’s own popularity.

In fact, Prabowo used to be among Jokowi’s greatest rivals before becoming his defence minister in 2019.

In previous elections, Prabowo presented himself as a firebrand populist who angrily denounced his opponents for allegedly selling Indonesia out to foreigners. He promised he would provide the strong hand the country needed to become truly great.

We don’t know yet what kind of president Prabowo will be. His early political socialisation, as a leading elite figure close to the heart of the Suharto regime, suggests his instincts are likely to be deeply authoritarian.

He inherits from Jokowi a country in which democratic institutions have already been seriously undermined, and a series of lessons in how to weaken them further.

China’s government is about to spend big on stimulus – can it turn around the country’s sluggish economy?

Source: The Conversation (Au and NZ) – By Wenting He, PhD candidate of International Relations, Australian National University

Sanga Park/Shutterstock

China’s relentless economic growth used to be the marvel of the world. Oh, what a memory.

The past couple of years have seen China contend with an economic slowdown amid colliding crises, many of which make it internationally unique. Consumer prices have been approaching deflationary territory, there’s an oversupply of housing, and youth unemployment has soared.

Mounting pressure has forced the Chinese government to step in. Over the past month, Beijing has put forward a set of significant economic stimulus measures aimed at reviving China’s faltering economy.

According to a research note by Deutsche Bank, this stimulus could potentially become “the largest in history” in nominal terms. But there’s still a lot we don’t know. So what kinds of measures that are in this package so far, and has China been here before?

What’s in the package?

On September 24, Pan Gongsheng, governor of China’s central bank, unveiled the country’s boldest intervention to boost its economy since the pandemic.

The initiatives included reducing mortgage rates for existing homes and reducing the amount of cash commercial banks are required to hold in reserves. The latter is expected to inject about 1 trillion yuan (A$210 billion) into the financial market by letting the banks lend out more.

On top of this, 800 billion yuan (A$168 billion) was announced to strengthen China’s capital market.

This comprised a new 500 billion yuan (A$105 billion) monetary policy facility to help institutions more easily access funds to buy stocks, and a 300 billion yuan (A$63 billion) re-lending facility to help speed up sales of unsold housing.

Further signs of economic revitalisation became evident at a Politburo meeting of China’s top government officials, two days after this announcement.

Chinese President Xi Jinping stressed the urgency of economic revival. Xi even encouraged officials to “go bold in helping the economy” without having to fear the consequences.

That same day, seven government departments released a joint policy package to stabilise China’s 500 billion yuan (A$105 billion) dairy industry, which has been severely impacted by declining milk and beef prices since 2023.

A market rollercoaster

Initially, the market’s response was overwhelmingly positive. Perhaps too positive. In the last week of September, stock markets in Shanghai, Shenzhen, and Hong Kong saw their biggest weekly rise in 16 years.

On October 8, following China’s National Day holiday, turnover on the Shanghai and Shenzhen stock exchanges hit an unprecedented 3.43 trillion yuan (A$718 billion). However, expectations for further stimulus measures were met with disappointment.

China’s National Development and Reform Commission brought forward 100 billion yuan (A$21 billion) in spending from the 2025 budget. That wasn’t enough to sustain market optimism. On October 9, Chinese stocks saw their most severe drop in 27 years.

This downturn only worsened a few days later, when China’s Ministry of Finance hinted there was “ample room” to raise debts but did not specify any new stimulus measures.

Still thin on the details

The market remains deeply uncertain about the future direction of China’s economic policies and what they might mean for the world. Hopes that more details might be released over the weekend were largely dashed.

Back in July, Chinese authorities asserted in their Third Plenary Session communique that China “must remain firmly committed” to achieving this year’s economic growth target of 5%. Compared to the country’s reform-era economic performance, that’s a modest goal.

But facing a persistently sluggish economic outlook, Xi later seemed to subtly shift the tone, changing the language from “remain firmly committed” to “strive to fulfill” in September.

Over the past decades, China has frequently employed massive-scale stimulus measures to revive its economy during downturns. These policies have been able to significantly rejuvenate the economy, though occasionally with some worrying side effects.

In response to the 2008 global financial crisis, China’s State Council released a 4 trillion yuan (A$837 billion) stimulus package. This successfully helped China stand firm through the crisis and was credited as a key stabiliser of the global economy.

But it also accumulated trillions of yuan in debt through local government financing and accelerated the rise of “shadow banking” – unregulated financial activities.

China also spent big on stimulating its economy in 2015, following stock market turbulence, and then again in the wake of the pandemic.

What should we expect?

What should we expect this time? How balanced or sustainable will any ensuing growth be?

We are still waiting on many of the details about the size and scope of the package, but any big increase in Chinese economic demand will likely have “spillover” effects.

As we’ve discussed, many of the measures announced to date will have their most immediate effect on borrowing, lending and liquidity in China’s stock markets.

That suggests we should watch for what’s called the “wealth effect” in economics. This is the theory that rising asset prices – such as for housing or shares – make people feel wealthier and therefore spend more.

If China’s big stimulus spend causes sustained increases in asset values, it could give rise to economic optimism. Chinese consumers – and investors – may become less anxious about the future.

From Australia’s point of view, that could see increases in demand in areas where our economies are interlinked – iron ore, tourism, education and manufactured food exports.

More broadly, Chinese demand could contribute to growth in other global economies, with a self-reinforcing effect on the world as a whole.

Beware financialisation

On the other hand, China’s shift to depending more on volatile asset price rises in its capital markets to sustain growth could have destabilising effects. Where asset price increases benefit those at the “top end of town,” they can breed inequities and imbalances of their own.

China’s “Black Monday” stock market crash in 2015 raised alarm in Beijing. Partly reflecting a wariness of excess financialisation, Xi cautioned at the time that “housing is for living in, not for speculation”.

So far, China is still navigating its path towards a more sustainable development model, striving to strike a balance between sustaining economic growth and stabilising its domestic markets and political landscape. As for the outcome, it remains a profound uncertainty for us all – perhaps China itself included.

AI is creeping into the visual effects industry – and it could take the human touch out of film and TV

Source: The Conversation (Au and NZ) – By AD Narayan, Visual Effects Artist and Lecturer in Digital Communication, Auckland University of Technology

IMDB

From the mind-bending reality warps of Doctor Strange in the Multiverse of Madness (2022) to the breathtaking alien vistas of Avatar: The Way of Water (2022), visual effects have transported us to worlds beyond imagination. Yet the future of visual effects (VFX) could hang in the balance as artificial intelligence is subsumed into screen production processes.

Lionsgate’s recent partnership with AI startup Runway has sparked controversy in the visual effects industry.

By allowing Runway to train AI on Lionsgate’s vast film and TV catalogue, the collaboration promises increased efficiency and financial savings – but at what cost?

Growing apprehension among workers

According to a research report published in January, 75% of 300 entertainment industry leaders surveyed said generative AI tools, software and models had contributed to the elimination, reduction or consolidation of jobs within their business divisions.

The report highlighted the visual effects sector as being particularly vulnerable, as AI techniques are often applied in post-production processes. This vulnerability was typified in our own research published today.

Our work reveals visual effects artists have serious concerns about generative AI’s integration into screen production. These include worries over job insecurity, creative devaluation, and the potential for AI to produce derivative content that fails to meet audience expectations.

Challenges of AI in the VFX industry

Our findings reflect growing concerns that AI’s use in filmmaking could magnify existing industry problems. It could, for instance, exacerbate unfair working conditions. Or it could undermine creativity if artists are expected to “clean up” AI-generated work rather than create their own.

Visual effects artists, who have typically been early adopters of new technologies, acknowledge AI could bring both opportunities and challenges. While it could help streamline certain tasks, it could equally impact on the overall quality of their work.

The artists we spoke to were worried a reliance on AI might stifle creativity and skill development, by making the work “more mechanical and less creative”. In a recent example, the AI-generated title sequence for Marvel’s Secret Invasion series was widely criticised for lacking artistic merit.

There were also questions about how artists would be compensated if their work is used to train AI models.

Some senior supervisors were particularly concerned about the ethical and legal considerations of using AI on commercial projects. They were uncertain around intellectual property rights for AI-generated content, as well as the potential for copyright infringement.

On the creative and technical front, artists recognised AI’s value in generating ideas and automating repetitive tasks. However, nearly all of them said AI tools weren’t yet production-ready, and highlighted difficulties with integrating said tools into existing pipelines.

The next steps

The VFX industry was already struggling with profits and sustainability before the AI boom. Visual effects companies often face bankruptcy – even Oscar-winning ones. In many cases, artists will get laid off once a project is complete.

Life of Pi (2012) won an Oscar for its visual effects work – but the company responsible for it went bankrupt.
IMDB

The partnership between Lionsgate and Runway represents the industry’s collective failure to address concerns over AI. But there’s still time to fix things.

The first step is developing clear industry guidelines for AI’s use in visual effects. Above all else, AI should help augment human creativity, rather than replace it. And artists should be fairly compensated if their work is used to train AI models.

Investment in training programs could also help artists adapt to new AI tools without compromising their creativity. As one interviewee told us, human expertise and creativity remain important in visual effects.

“Understanding the why behind certain choices, the creative decision making, that’s something I haven’t really seen AI effectively do,” they said.

As the industry stands at a technological crossroads, it must balance the pursuit of efficiency with genuine creativity. Otherwise, we risk losing the human touch that brings our favourite films to life.

Three letters, one number, a knife and a stone bridge: how a graffitied equation changed mathematical history

Source: The Conversation (Au and NZ) – By Robyn Arianrhod, Affiliate, School of Mathematics, Monash University

On October 16 1843, the Irish mathematician William Rowan Hamilton had an epiphany during a walk alongside Dublin’s Royal Canal. He was so excited he took out his penknife and carved his discovery right then and there on Broome Bridge.

It is the most famous graffiti in mathematical history, but it looks rather unassuming:

²

 = j 

²

 = k 

²

 = ijk = 

–1

Yet Hamilton’s revelation changed the way mathematicians represent information. And this, in turn, made myriad technical applications simpler – from calculating forces when designing a bridge, an MRI machine or a wind turbine, to programming search engines and orienting a rover on Mars. So, what does this famous graffiti mean?

Rotating objects

The mathematical problem Hamilton was trying to solve was how to represent the relationship between different directions in three-dimensional space. Direction is important in describing forces and velocities, but Hamilton was also interested in 3D rotations.

Mathematicians already knew how to represent the position of an object with coordinates such as x, y and z, but figuring out what happened to these coordinates when you rotated the object required complicated spherical geometry. Hamilton wanted a simpler method.

He was inspired by a remarkable way of representing two-dimensional rotations.
The trick was to use what are called “complex numbers”, which have a “real” part and an “imaginary” part. The imaginary part is a multiple of the number i, “the square root of minus one”, which is defined by the equation i ² = –1.

By the early 1800s several mathematicians, including Jean Argand and John Warren, had discovered that a complex number can be represented by a point on a plane. Warren had also shown it was mathematically quite simple to rotate a line through 90° in this new complex plane, like turning a clock hand back from 12.15pm to 12 noon. For this is what happens when you multiply a number by i.

When a complex number is represented as a point on a plane, multiplying the number by i amounts to rotating the corresponding line by 90° anticlockwise.
The Conversation, CC BY

Hamilton was mightily impressed by this connection between complex numbers and geometry, and set about trying to do it in three dimensions. He imagined a 3D complex plane, with a second imaginary axis in the direction of a second imaginary number j, perpendicular to the other two axes.

It took him many arduous months to realise that if he wanted to extend the 2D rotational wizardry of multiplication by i he needed four-dimensional complex numbers, with a third imaginary number, k.

In this 4D mathematical space, the k-axis would be perpendicular to the other three. Not only would k be defined by k ² = –1, its definition also needed k = ij = –ji. (Combining these two equations for k gives ijk = –1.)

Putting all this together gives i ² = j ² = k ² = ijk = –1, the revelation that hit Hamilton like a bolt of lightning at Broome Bridge.

Quaternions and vectors

Hamilton called his 4D numbers “quaternions”, and he used them to calculate geometrical rotations in 3D space. This is the kind of rotation used today to move a robot, say, or orient a satellite.

But most of the practical magic comes into it when you consider just the imaginary part of a quaternion. For this is what Hamilton named a “vector”.

A vector encodes two kinds of information at once, most famously the magnitude and direction of a spatial quantity such as force, velocity or relative position. For instance, to represent an object’s position (xyz) relative to the “origin” (the zero point of the position axes), Hamilton visualised an arrow pointing from the origin to the object’s location. The arrow represents the “position vector” x i + y j + z k.

This vector’s “components” are the numbers x, y and z – the distance the arrow extends along each of the three axes. (Other vectors would have different components, depending on their magnitudes and units.)

A vector (r) is like an arrow from the point O to the point with coordinates (x, y, z).
The Conversation, CC BY

Half a century later, the eccentric English telegrapher Oliver Heaviside helped inaugurate modern vector analysis by replacing Hamilton’s imaginary framework i, j, k with real unit vectors, i, j, k. But either way, the vector’s components stay the same – and therefore the arrow, and the basic rules for multiplying vectors, remain the same, too.

Hamilton defined two ways to multiply vectors together. One produces a number (this is today called the scalar or dot product), and the other produces a vector (known as the vector or cross product). These multiplications crop up today in a multitude of applications, such as the formula for the electromagnetic force that underpins all our electronic devices.

A single mathematical object

Unbeknown to Hamilton, the French mathematician Olinde Rodrigues had come up with a version of these products just three years earlier, in his own work on rotations. But to call Rodrigues’ multiplications the products of vectors is hindsight. It is Hamilton who linked the separate components into a single quantity, the vector.

Everyone else, from Isaac Newton to Rodrigues, had no concept of a single mathematical object unifying the components of a position or a force. (Actually, there was one person who had a similar idea: a self-taught German mathematician named Hermann Grassmann, who independently invented a less transparent vectorial system at the same time as Hamilton.)

Hamilton also developed a compact notation to make his equations concise and elegant. He used a Greek letter to denote a quaternion or vector, but today, following Heaviside, it is common to use a boldface Latin letter.

This compact notation changed the way mathematicians represent physical quantities in 3D space.

Take, for example, one of Maxwell’s equations relating the electric and magnetic fields:

 

×

 

E

 

= –∂
B
/∂

t

With just a handful of symbols (we won’t get into the physical meanings of ∂/∂t and ∇ ×), this shows how an electric field vector (E) spreads through space in response to changes in a magnetic field vector (B).

Without vector notation, this would be written as three separate equations (one for each component of B and E) – each one a tangle of coordinates, multiplications and subtractions.

The expanded form of the equation. As you can see, vector notation makes life much simpler.

The power of perseverance

I chose one of Maxwell’s equations as an example because the quirky Scot James Clerk Maxwell was the first major physicist to recognise the power of compact vector symbolism. Unfortunately, Hamilton didn’t live to see Maxwell’s endorsement. But he never gave up his belief in his new way of representing physical quantities.

Hamilton’s perseverance in the face of mainstream rejection really moved me, when I was researching my book on vectors. He hoped that one day – “never mind when” – he might be thanked for his discovery, but this was not vanity. It was excitement at the possible applications he envisaged.

A plaque on Dublin’s Broome Bridge commemorate’s Hamilton’s flash of insight.

He would be over the moon that vectors are so widely used today, and that they can represent digital as well as physical information. But he’d be especially pleased that in programming rotations, quaternions are still often the best choice – as NASA and computer graphics programmers know.

In recognition of Hamilton’s achievements, maths buffs retrace his famous walk every October 16 to celebrate Hamilton Day. But we all use the technological fruits of that unassuming graffiti every single day.

Has Kamala Harris reached the ceiling of her ability to make gains against Trump?

Source: The Conversation (Au and NZ) – By Jared Mondschein, Director of Research, US Studies Centre, University of Sydney

With less than three weeks to go before Election Day, the polling at this point is clear: Kamala Harris and Donald Trump are effectively tied.

Harris has led the Democratic ticket for less than three months, but in that short time she has galvanised Democratic voters and significantly increased the popularity of the Democratic ticket. Yet, current levels of US political polarisation and, perhaps more notably, calcification, make one wonder just how much more support she could win.

In other words, few Americans are undecided in their views of Donald Trump – he galvanises both his base and his opponents alike – so there are simply not many American voters remaining for Harris to try to win over.

Initial momentum has plateaued

When 81-year-old Joe Biden led the Democratic ticket in early 2024, only 55% of Democrats and Democratic-leaning voters were enthusiastic about the election.

While the 2020 presidential election between Biden and Trump broke records for US voter turnout, the 2024 redux was looking like it would break the opposite sort of records – for voter disinterest.

That is, at least, until Harris assumed the top of the Democratic ticket on 21 July 2024. Within a month of Biden stepping down as the party’s nominee, Democratic enthusiasm for their significantly younger candidate jumped 23 points to 78%. This eclipsed not only levels of enthusiasm that Democrats had for Barack Obama in 2008, but also the levels of enthusiasm that Republicans currently have for Donald Trump.

Harris’ momentum saw the race quickly move on from deep analysis of the “double haters” – the record 25% US voters who disliked both Trump and Biden and were simply deciding which they hated less. With a much closer contest now likely, attention shifted to key swing states such as Pennsylvania, where Harris closed Trump’s five-point lead over Biden to now be around even.

Small changes can make a big difference

Harris’ ability to make the Democratic ticket competitive should not be undervalued. After all, as recently as June 2024, she was one of the few Democratic politicians who actually had a lower national approval rating than Joe Biden.

With that said, the momentum for Harris should not be seen as a sea change across the country. As much as she energised a previously lacklustre Democratic ticket, approval of Harris among self-described Independent voters only increased from 36% to 43% in the same timeframe. Republican approval of Harris decreased slightly from 6% to 4% over the same period.

Ultimately, even the slightest of changes can completely shift the nature of the race, particularly given how slim the margins have been in the last two presidential elections. In the 2016 presidential election, for example, Trump’s margin of victory was some 75,000 votes across three swing states. In 2020, Biden’s margin of victory was about 45,000 votes across three swing states.

Harris or Trump’s 2024 margin of victory very well may be less than 0.03% of the US electorate, making this potentially the closest US election in decades.

Has support for Harris peaked?

For the first half of 2024, Trump polled considerably ahead of Biden in the key swing states that will most likely decide the US election. Then, within weeks of Harris becoming the presidential nominee in July, the difference in the swing states between Trump and his opponent shrank to around 1-2 percentage points.

Now, nearly three months later, the polling is essentially unchanged – remaining well within the standard margin of error of around ±3%.

As much as Harris has eclipsed Biden in the race against Trump, there is no denying the statistical reality that Harris is no longer gaining ground on Trump in the way that she was in the early weeks of her candidacy.

Some have argued that Harris’ liabilities – and perhaps the reason she has stalled in the polls – are that Americans remain fairly negative on the economy, she is in the incumbent administration instead of on an outsider ticket, and that many view her as simply too progressive.

Yet judging by the fact that Harris appears to be polling better than “a generic Democrat” – who generally are more popular than any other Democrats because they are not real people with real positions – it’s perhaps more likely that in these polarised and calcified times, Harris very well may have simply peaked as high as any other Democratic candidate possibly could.

With American voter intentions barely shifting after an insurrection, pandemic and assassination attempts, it’s hard to imagine Harris can do much better than she already is doing.

Harris’ best strategy for success on November 5 may therefore need to be less focused on winning over more of the very few undecided voters remaining, and instead more focused on simply getting her energised supporters to turn up on Election Day.

An immediate ban has been issued for the herbicide dacthal. What are the health risks?

Source: The Conversation (Au and NZ) – By Ian Musgrave, Senior lecturer in Pharmacology, University of Adelaide

Last week the Australian government cancelled the registration of all products containing chlorthal dimethyl, a weedkiller commonly known as dacthal.

No phase out period applies. The cancellation is immediate, due to the risks it poses to human health – primarily unborn babies.

This means using dacthal as a chemical agricultural product “is now illegal”, according the Australian Pesticides and Veterinary Medicines Authority.

So what has changed? What are the health risks of being exposed to dacthal – and how long have we known about them?

What is dacthal?

Dacthal and chlorthal dimethyl are alternative names for dimethyl tetrachloroterephthalate, or DCPA. This is a herbicide registered to control weeds in both agricultural and non-agricultural settings.

Dacthal works by inhibiting auxin, a growth hormone in plants which promotes the development of buds, roots and lengthening cells.

It is used to selectively kill annual grasses and many other common weeds, without killing turf grasses, flowers, fruits and vegetables. Dacthal is applied before weeds emerge, often when still in their seed stage.

In Australia it is used in twelve herbicide products. All have been cancelled as of October 10 2024.

Farmers and retailers are allowed to hold products until they’re recalled, but must not use them. The government says it will provide information about product recall shortly.

What are the health risks?

As dacthal targets a hormone found only in plants, for adult humans and mammals the chemical has limited acute and subchronic toxicity. This means brief exposure to high levels of dacthal, or longer-term exposure to modestly high levels, have no effect.

However there is a health risk for unborn babies whose mothers have been directly exposed. This could be through mixing the chemical, loading and applying it, or from residue on treated crops – for up to five days after first applied.

The chemical has been linked to low birth weight, and life-long impacts, which can include impaired brain development and motor skills.

The government has advised pregnant agricultural workers who are concerned to speak to their clinician.

What changed?

Safety data for chemicals such as pesticides are periodically reevaluated. This is to see if any new risks have become apparent with advances in technology and our understanding of biology.

In 2013, the United States Environmental Protection Agency called for fresh safety data to look at effects of dacthal on thyroid hormones.

Fast forward to 2022. In that time, the company producing dacthal had failed to produce the required study. So the US Environmental Protection Agency issued a notice it would suspend technical-grade products containing dacthal.

In response, the company submitted a thyroid study performed in rats. This study showed dacthal could affect thyroid function at doses lower than previously known.

The US government determined this did not change recommendations for adults. However dacthal may affect thyroid function of a fetus at lower doses than those those that harm adults.

What did the study in rats find?

Dacthal was found to inhibit two thyroid hormones in rat pups whose mother had been exposed while pregnant.

There was a 35-53% decrease in the hormone triiodothyronine, known as T3. And for thyroxine (T4), rat pups experienced a 29-66% decrease after their mother’s exposure.

Decreases in these two hormones are associated with risks to unborn children including low birth weight and impaired brain development, IQ and motor skills.

Of particular concern was the effects occurred at much lower levels than previously thought. The decreases in T3 and T4 occurred in rat pups exposed to levels of dacthal ten times lower than the safe threshold for their mothers. This means pregnant rats exposed to dacthal at those levels had no adverse effects, but their unborn babies did.

Exactly how the chemical caused decreases in T3 and T4 in rat pups is not clear.

However the Australian Pesticides and Veterinary Medicines Authority considers this study relevant to humans. The changes in regulation are based on the potential harms if unborn babies are exposed via their mothers.

The health risk is to the development of an unborn baby exposed to dachtal via their mother.

What exposure is safe?

The rat study was used to calculate maximum levels of exposure for pregnant workers. This maximum – 0.001 mg dachtal/kg body weight/day – was considered appropriate to reduce risk to the unborn child (and was not expected to harm adults).

However, the maximum acceptable level was exceeded in all estimates of exposure to dachtal. This was the case even when the person was wearing protective clothing, gloves, and using a respirator.

Even under stringent safety conditions, potential harms to an unborn child could not be ruled out. For this reason the US stopped sale of dacthal via an Emergency Order on 6 August 2024. Australia has since followed suit with its own ban.

How long have we known about this?

The US government only received the thyroid information in 2022. It then had to determine whether the levels of exposure under real world conditions would equate to risk in humans.

This is not straightforward, as the pesticide is used under a variety of conditions, including:

  • mixing and preparing the pesticide using personal protective equipment
  • downstream spay drift
  • treatment of lawns and exposure to the lawn after treatment.

Each of these scenarios requires careful analysis of potential risks.

In addition, exposure can be through inhalation and/or skin contact. All this must be taken into account and these calculations take time.

Should I be worried?

If you were not pregnant and using personal protective clothing while using or applying dacthal herbicides, this is little cause for worry. Your exposure is below the maximum limit.

But if you were pregnant when using dacthal pesticides, please consider consulting your child’s paediatrician.

Australian schools need to address racism. Here are 4 ways they can do this

Source: The Conversation (Au and NZ) – By Aaron Teo, Lecturer in Curriculum and Pedagogy, University of Southern Queensland

The Australian Human Rights Commission wants to see schools address racism, as part of a broader push to address the problem across Australian society.

As it says in a recent report,

People are not born with racist attitudes or beliefs […] Addressing racism in schools is crucial to ensure that victims do not leave education facing lifelong disadvantage, and perpetrators do not enter adulthood believing racist behaviours are acceptable […].

But racism is hardly mentioned in the Australian Curriculum – for example, it is noted in passing in the health and physical education curriculum for years 5 to 8. However, there is no consistent approach across subject areas, or at the state level.

This means teaching about racism is largely left up to individual schools and teachers.

Yet research shows they can be reluctant to speak about these issues with students. This is for a range of reasons, such as worrying they will say the wrong thing.

How should school systems, schools and teachers address racism? Here are four ways.

1. Teach racial literacy

We know children demonstrate stereotyping and prejudice from an early age and students from racial minorities are frequently targets of racism and discrimination at school.

In Australia, racism debates can also involve dangerous and ill-informed opinions.

So we need to start teaching children and young people about racial literacy skills from the first year of schooling. This means they grow up to have the knowledge and language to talk about and confront racism.

Some of these skills include:

  • being able to identify how racism appears in everyday interactions, the media and society more broadly

  • debunking common myths about racism, such as it is a “thing of the past”. Or “everyone has equal access to the same opportunities and outcomes if they work hard enough”

  • understanding the impacts of racism, including on people’s opportunities, education and their health and wellbeing

  • understanding how our own backgrounds, privilege and bias can influence how we confront or don’t confront racism.

Students also need to learn how racism can be structural, systemic and institutional. This means racism is not just about an individuals’ beliefs or actions. Laws, policies, the way organisations are run and cultural norms can all result in inequitable treatment, opportunities and outcomes.

2. Teach students how to react

We also need to teach children how to react when they witness racism with age-appropriate tools.

For both primary and secondary students, the first question should always be, “Is it safe for me to act?”, followed by “Am I the best person to act in this situation?”. Depending on their answers, they could:

  • report the incident to an appropriate adult or person in authority

  • show solidarity with the victim by comforting them and letting them know what happened was not OK

  • interrupt, distract or redirect the perpetrator

  • seek help from friends, a passerby or teacher.

3. Create safe classrooms and playgrounds

Teachers need to ensure classrooms and schools are safe spaces to discuss racism.

This can include:

  • acknowledging how our own experiences, biases and privileges shape our world views

  • clearly defining the purpose of a discussion and the ground rules

  • using inclusive language.

In particular, schools have a unique duty of care for minority students, who need to know they can talk openly about these issues with their peers and teachers without fear or judgement.

This includes addressing sensitive topics like how they might experience or witness racism, the effect it can have on their health and wellbeing and those around them, and the consequences of talking about or reporting racism.

4. Develop teachers’ skills

As part of creating safe classrooms, teachers need to be able to confidently discuss tricky topics in an age-appropriate way.

Our work has shown some teachers deny racism or perpetuate racist stereotypes. Others may avoid the topic, worrying they will say or do the wrong thing.

Our current (as yet unpublished) research on anti-racism training with classroom teachers suggests they can increase their confidence to talk and teach about racism if given appropriate, and sustained training.

What needs to happen now?

We need anti-racism education to be an official part of school curricula. To accompany this, we need genuine commitments and modelling from policymakers, school leaders, teachers, parents and carers to address racism in schools.

We need to talk openly about racism in schools. That means explicitly naming it, calling it out, and not getting defensive when it is identified and action is required.

Austerity and recession: 3 simple graphs that explain New Zealand’s economic crisis

Source: The Conversation (Au and NZ) – By Geoff Bertram, Visiting Scholar, School of History, Philosophy, Political Science and International Relations, Te Herenga Waka — Victoria University of Wellington

Economists working on macroeconomic policy – things like taxes and spending, interest rates and border controls on flows of trade and money – often refer to a set of key relationships governments can influence. In the textbooks, each of those relationships is drawn as a curve in a graph.

First is the IS (“investment–saving”) curve. This says that if everything else stays the same, the Reserve Bank can increase economic output and employment by lowering the interest rate. Or it can cause a recession by raising the interest rate. (For simplicity’s sake, the curves here are depicted as straight lines.)



Second comes the Phillips Curve, which is usually drawn sloping upwards to suggest that if everything else stays the same, inflation will rise during economic booms and fall in recessions. In other words, the Reserve Bank or the government can apparently bring inflation down by causing a recession.



Third comes the trade balance – the current account of the balance of payments (investment income and traded goods and services between New Zealand and the rest of the world).

If everything else stays the same here, as the exchange rate of the dollar falls, the current account strengthens by moving towards or expanding a surplus. If the exchange rate rises, the current account weakens: exports fall and imports increase.



However, it’s a mistake to suppose each of these relationships will stay where it is while the government and Reserve Bank each tinker with their own policy settings. So, what could go wrong?

The effect of austerity

Start with the IS curve – the way output and employment are affected by interest rates, assuming the government makes no big budgetary changes. But what if the government embarks on an austerity program, slashing its spending and cancelling projects, which shrinks the economy?



At any given interest rate, output and employment will be lower, shifting the whole curve “leftwards” towards lower economic activity (see above).

Even if the Reserve Bank lowers the interest rate, that won’t expand the economy because the government’s fiscal policy is killing off its expansionary effect. The recession created by the austerity program rolls on.

Along the way, it increases costs to government from unemployment, paying other benefits, and lower tax revenue. If the government responds with further austerity, we enter a downward self-reinforcing spiral.

Wages and inflation

Second, take the Phillips Curve and ask what happens if inflation isn’t, in fact, sensitive to how the economy is doing.



In this case, driving the economy into recession has no effect on the inflation rate. When the Reserve Bank changes the interest rate, inflation just stays where it is because the Phillips Curve is flat, not upward-sloping. Reducing inflation requires completely different policy interventions.

Back when the Phillips Curve was invented, it was reasonable to think inflation fell during recessions because workers could get higher wage increases in booms than in slumps.

Bringing on a recession would reduce the bargaining power of workers, result in slower wage growth, and thereby tame inflation (given that wages are an important part of the costs of production).

But workers today have lost the bargaining power they used to have when unions were strong and welfare-state thinking prevailed.

In a paper fellow economist Bill Rosenberg and I published this year, we show the bargaining power of labour was killed off in 1991 by the Employment Contracts Act and has not recovered since. Wages no longer drive inflation in contemporary New Zealand.

Interest rates and inflation

Could the Phillips Curve work because producers of goods and services push up prices and profits faster in booms and cut their margins in recessions?

It’s possible: there’s plenty of evidence of big companies using their market power to price-gouge consumers. But it’s not clear this exercise of market power is greater in booms and lesser in slumps.

In fact, the opposite could be true. Small businesses are most likely to be driven out of the market in recessions, leaving big companies with increased market share and less competitive pressure on their margins.

Forces both locally and in international markets have clearly been pushing the Phillips Curve down, producing lower inflation. Local forces include the current government’s abrupt cancellation of major construction activities, dismissal of public servants, the constant negative messaging on the state of the economy, and rising outward migration as a consequence of all these.

International markets, including falling prices for imports such as oil, have also clearly been pushing the Phillips Curve down. While the Reserve Bank will claim credit, it’s not at all clear the bank’s interest rate policy has made that much difference.

Finally, what about the international balance of payments? One thing the Reserve Bank can do by changing the interest rate is change the exchange rate between the New Zealand dollar and other currencies.

If New Zealand’s interest rates increase relative to elsewhere in the world, short-term money flows in to take advantage of the higher rates. This raises the exchange rate, and in turn weakens the external balance by cutting the return on exports and increasing the volume of cheaper imports.

Producers of goods and services that face international competition are squeezed. Meanwhile, what used to be called the “sheltered” or “non-tradeable” industries – including the big banks, insurance companies, electricity suppliers, supermarkets, consultancies – are unscathed.

Deeper recession

The Reserve Bank may not have much effect on inflation, but it can certainly affect the structure of the economy. Using the interest rate as the weapon against inflation squeezes manufacturers, tourism and farmers, but leaves non-tradables largely untouched.

Right now in New Zealand, the IS curve is remorselessly shifting left as the economy plunges into a deeper recession exacerbated by government austerity – an ideologically driven quest for instant fiscal surpluses, low public debt and a shrinking public sector relative to GDP.

Falling interest rates will struggle to make expansionary headway against that austerity.

Meanwhile, corporate profiteering and rising government charges continue to put upward pressure on the Phillips Curve, and the balance of payments is weakening. This means the country as a whole is piling up increasing debts to the rest of the world (largely through the Australian-owned banks).

The question is, does the current government understand where its policies are taking us?

Albanese government promises to ban ‘dodgy’ trading practices

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Hard on the heels of pledging a crackdown on excessive surcharges, the Albanese government has promised legislation to ban unfair trading practices.

The government said this would include specific prohibitions on various “dodgy” practices.

“From concert tickets to hotel rooms to gym memberships, Australians are fed up with businesses using tricky tactics that make it difficult to end subscriptions or add hidden fees to purchases,” the prime minister, treasurer and assistant treasurer said in a statement.

“These practices can distort purchasing decisions, or result in additional costs, putting more pressure on the cost of living.”

They said the government would deal with

  • “subscription traps” that make it difficult to cancel a subscription

  • “drip pricing” characterised by hidden fees or fees added during the purchase

  • deceptive and manipulative online practices. These aim to confuse consumers, such as for example by creating a false sense of urgency, warning there is only a limited time to purchase

  • dynamic pricing, where a price changes during the transaction

  • requiring a consumer to set up an account and provide unnecessary information for an online purchase

  • a business making it difficult for a consumer to contact it when they have a problem with the product.

Earlier this week Arts Minister Tony Burke said on the ABC the government was not looking at “dynamic pricing” in the music industry.

Asked on Four Corners whether dynamic pricing should be allowed in Australia, Burke said: “Surge pricing is something that, as consumers, people have always dealt with.

“I don’t love it, but I think we have to be realistic, it’s always been there. It’s not something we’re looking at, at the moment.”

Asked about the discrepancy, a government spokesperson said the Four Corners interview “was recorded a month ago, before this policy existed”.

Treasury will consult on the design of the planned changes. The government on Wednesday will put out a consultation paper on reforms for greater protections for consumers and small businesses under the consumer guarantees and supplier indemnification in the Australian Consumer Law.

The government says it will work with the states to have a final reform proposal in the first half of next year.

There will be penalties for suppliers that refuse to give consumers a remedy such as a replacement product or a refund when legally required.

“Currently, it can be difficult for consumers to obtain a remedy, especially when engaging in the digital economy,” the government statement said.

The reforms would empower the Australian Competition and Consumer Commission and state and territory agencies to pursue breaches of consumer guarantees and supplier indemnification provisions.

Prime Minister Anthony Albanese said “hidden fees and traps are putting even more pressure on the cost of living and it needs to stop”.

Fair-minded, down to earth and unusually gifted: George Negus dies at 82

Source: The Conversation (Au and NZ) – By Denis Muller, Senior Research Fellow, Centre for Advancing Journalism, The University of Melbourne

George Negus, who has died at the age of 82, belonged to the nomenclatura of Australian television current affairs journalism.

He first came to prominence as a member of the team that produced the groundbreaking nightly ABC TV current affairs program, This Day Tonight. That team was made up of others who were also to become household names: presenter Bill Peach and reporters Peter Luck, Gerald Stone and Mike Willesee.

The program became a burr under the saddle of senior ABC management. On its second day it broke the story that the then chair of the ABC, James Darling, was not to be given a third term. The story incurred the chairman’s displeasure. The fallout went on interminably, a rehearsal for many tumults that were to follow throughout TDT’s 11-year existence.

This kind of fearless, sometimes irreverent, public-interest journalism was meat and drink to Negus. He practised it from both sides of the chasm that traditionally separates journalists from political staffers.

During the term of the Whitlam government, he became press secretary to the attorney-general, Lionel Murphy. He leaked to the media Murphy’s plan to raid the headquarters of the Australian Security Intelligence Organisation (ASIO) in 1973 because Murphy believed the agency was withholding from him information about domestic terrorism.

However, it was as a television journalist that Negus made his name. In 1979 he joined the founding team of the Nine Network’s 60 Minutes program, alongside Ray Martin, Ian Leslie and, later, Jana Wendt.

In 1992 he became the founding host of ABC TV’s Foreign Correspondent program and worked there until 1999. He developed a reputation as a well-informed and courageous reporter specialising in the Middle East. In 2004, he published a bestselling book, The World from Islam: A Journey of Discovery through the Muslim Heartland, in which he defended Islam against the stereotype that it was inherently violent.

In 2005 he became host of the SBS program Dateline, which also had a foreign affairs focus, and in 2011 began hosting 6.30 with George Negus on the Ten network.

In 2012, Negus and a fellow panellist on the Ten network show The Circle, Yumi Stynes, became embroiled in a controversy concerning remarks they made about Ben Roberts-Smith, many years before he was found by a federal court judge to have committed war crimes, a finding that is now on appeal.

There was severe public blowback on Negus and Stynes, who then apologised to Roberts-Smith. They in turn received apologies from Australia’s major newspapers for misconstruing the original remarks.

In 2015 he was made a Member of the Order of Australia for services to media and environmental conservation.

Although he acquired a knockabout image, he was described by two women who worked with him as disarmingly approachable.

Nehida Barakat was the senior producer for the ABC’s 7.30 program in about 2000 when Negus stood in as the summer presenter. She was apprehensive when he rang to discuss an intro she had written. “This gentlemanly voice asked: ‘Would you mind if I changed just a couple of words?’”

Nicole Chvastek, who worked with him at Nine, said he was a big star who generated an air of excitement, a mixture of the intelligent, well-travelled journalist and “a sort of approachable larrikin everyman”.

It was his down-to-earth approach to storytelling that viewers related to so readily. This, coupled with unshakeable fairmindedness on the issues he reported on, marked him out as an unusually gifted journalist.

He is survived by his partner, Kirsty, and two sons, Ned and Serge. The family released a statement saying he had “passed away peacefully surrounded by loved ones after a gracious decline from Alzheimer’s disease, all the while with his trademark smile”.

Banning debit card surcharges could save $500 million a year – if traders don’t claw back the money in other ways

In a move that could reshape how Australians pay for everyday purchases, the federal government is preparing to ban businesses from slapping surcharges on debit card transactions.

This plan, pending a review by the Reserve Bank of Australia (RBA), promises to put money back into consumers’ pockets.

The RBA, which is accepting submissions until December, released its first consultation paper on Tuesday to coincide with Prime Minister Anthony Albanese and Treasurer Jim Chalmers’ joint announcement.

But as with any significant policy shift, it’s worth taking a closer look to see what it really means for all of us.

How much are we really saving?

Based on RBA data, the potential savings are huge – up to $500 million a year if surcharges on debit cards are banned.

And if the government goes one step further and includes credit card transaction fees in the ban, those savings could hit a massive $1 billion annually.

While these figures sound impressive, when you break it down, the savings per cardholder would amount to around $140 annually.

It’s not a life-changing amount, but for frequent shoppers or anyone making larger purchases, it could add up.

Of course, not everyone will benefit equally. Those who shop less might not notice the difference.

How does Australia stack up globally?

RBA data shows Australians are paying more in merchant service fees than people in Europe, but less than consumers in the United States.

These fees are what businesses pay to accept card payments, and they get passed on to us in the form of surcharges.



The proposed ban on debit card surcharges occupies a middle ground in the global regulatory landscape. The European Union, United Kingdom and Malaysia have implemented comprehensive bans on surcharges for most debit and credit card transactions.

But in the US and Canada, businesses can still charge you for using a credit card, though debit card surcharges aren’t allowed.

The merchant’s perspective

While the surcharge ban seems like a clear win for consumers, it’s essential to consider the impact on merchants, especially small businesses. The reality is not all merchants are created equal when it comes to card payment fees.

In Australia, there’s a significant disparity between the fees paid by large and small merchants. In fact, RBA data shows small businesses pay fees about three times higher than what larger businesses pay.

It all comes down to bargaining power. Bigger businesses can negotiate better deals on fees. This difference is primarily driven by the ability of larger merchants to thrash out favourable wholesale fees for processing card transactions.

For small businesses, the cost of accepting cards can range from under 1% to more than 2% of the transaction value, which can eat into profits, especially for those working with tight margins.

While the ban may sound like good news for consumers, there’s still a need to fix the bigger issues in the payment system. Innovations like “least-cost routing”, which allows businesses to process transactions at the lowest possible cost, could potentially help level the playing field.

How businesses might exploit the loopholes?

If payment costs are entirely passed on to merchants, they might find ways to recover those expenses through other means. We’ve seen this happen in other countries that abolished surcharges. Some potential strategies include

  • slightly raising overall prices to cover lost surcharge revenue
  • implementing or increasing minimum purchase requirements for card payments
  • introducing new “service” or “convenience” fees for all transactions, or increasing weekend and holiday surcharges.

Most of these tactics have been around for a while. The challenge for regulators will be to monitor and address any new practices that emerge in response to the new rules.

Credit cards: the elephant in the room

While the ban on debit card surcharges is a step in the right direction, it raises an obvious question: why not extend it to credit cards?

The option to ban credit card surcharges along with debit cards is proposed in the RBA’s review consultation paper. The answer lies in the complex web of interchange fees and merchant costs associated with credit card transactions.

Credit card transactions cost merchants more to process because of additional services and rewards programs offered by credit card issuers.

Banning surcharges on these could potentially lead to merchants increasing their base prices to cover these costs. This could effectively result in users of lower-cost payment methods subsidising those opting for premium cards.

The absence of surcharges could also reduce the competitive pressure on card networks to keep their fees in check, potentially leading to higher costs in the long run.

Some countries have managed to ban surcharges on credit cards, but they usually have stricter regulations around interchange fees than we do in Australia.

As policymakers grapple with this complex issue, they must weigh the benefits of consumer simplicity against the risk of distorting market signals and potentially increasing costs for both merchants and consumers alike.
