The withdrawal of major banks from Pacific islands poses significant socio-economic risks to the region, prompting intervention by Australia, the US and New Zealand.

The so-called debanking of the Pacific – when banks close or restrict accounts because they believe customers pose regulatory, legal, financial or reputational risks to their operations – was the focus of discussions at this week’s Pacific Banking Forum in Brisbane.

Australian Prime Minister Anthony Albanese and US President Joe Biden announced the forum last year to deal with growing concerns about the loss of correspondent banking relationships in the Pacific.

Correspondent banks provide banking services to other financial institutions overseas.

For example, a person in Vanuatu might want to send money to someone in Australia, where their local bank may not operate, so another Australian bank will facilitate the transaction on behalf of the Vanuatu bank.

While these relationships have declined globally in the past decade, the fall in the Pacific has been particularly steep. Between 2011 and 2022, the region lost about 60% of its correspondent relationships.

These relationships are significant because, among other things, they enable domestic banks to make and receive international payments. When foreign trade payments cannot be made, trade is threatened.

Also, many Pacific communities rely on money remitted by family members working overseas. In 2022, remittance receipts amounted to 44% of the gross domestic product (GDP) in Tonga, 34% in Samoa and 15% in Vanuatu.

Yet the value of these remittances is eroded by banking costs that consistently rank among the highest globally. In the fourth quarter of 2022, the average remittance cost in the Pacific was 9.1% of the transaction value – more than triple the global target of 3%.

Why is the Pacific facing a debanking crisis?

The provision of banking services in the region is challenged by the vast distances and small populations of Pacific Islands.

Foreign bankers also have to navigate different laws, regulations and risks of each jurisdiction. While general crime risks may be relatively low in the region, organised crime is increasing.

Money laundering laws require bankers mitigate financial integrity risks relevant to each jurisdiction and business relationship. This adds to the complexity and costs of each banking relationship. In some cases, bankers respond to this risk by terminating or limiting the relationship.

Pacific Islands such as the Marshall Islands are left with one bank and it is expected it might also close.

While other Pacific Islands – including Samoa, Tonga and Tuvalu – may have a higher number of banking relationships, some services have been limited or are provided at a higher cost.

Why the US, NZ and Australia are involved

This week’s Pacific Banking Forum, co-hosted by the Australian and US governments, drew together a wide range of debanking stakeholders.

Officials of governments, central bank governors, regulators, domestic and foreign bankers and representatives of international financial institutions and the Pacific Islands Forum joined to consider the drivers of debanking and potential solutions.

In his keynote address at the forum, Australian Treasurer Jim Chalmers pointed to the importance of these services for local communities as the reason why his government has

been actively talking to all the major Australian banks to let them know how important a continued Australian banking presence in the region is to the government.

Forum speakers also recognised the benefits of healthy and resilient cross-border correspondent banking relationships.

In her video remarks to the forum, US Secretary of the Treasury Janet Yellen noted that correspondent banking

promotes healthy market competition in the financial services sector; facilitates trade financed through regional and global financial centers; enables financing for infrastructure and development projects; and helps to make economies and financial systems more resilient to shocks.

Positive change

The Pacific debanking tide may be turning. In 2023, the Pacific Islands Forum commissioned and adopted a debanking study of the World Bank. They also adopted a roadmap of actions informed by the study to make correspondent banking more resilient in the region.

Discussion about the problem now involves Australian, New Zealand and US banks and their regulators. US, Australian and New Zealand dollars are key trade currencies for Pacific jurisdictions and correspondent banking services are important to the economic health of the region.

At the Brisbane forum, a number of Pacific representatives acknowledged the problem of scale in the Pacific and spoke in favour of regional solutions, aggregation of transactions and greater consistency of laws and processes.

International bankers and regulators, on the other hand, positioned the need for compliance with global anti-money laundering standards and the benefits of improved national identification systems, digital identity and appropriate technology.

While definitive solutions will take time to implement, the World Bank is considering a regional solution that will support temporary access to correspondent banking services if a country loses its last banking service in a key currency.

This will provide the relevant jurisdictions with access to appropriate services while they secure services by another correspondent bank. Such a facility will ease the immediate pressure on the Pacific and allow time for more sustainable solutions to be developed and implemented.

The Australian treasurer also pledged A$6.3 million in funding to secure digital identity infrastructure in the Pacific, improve compliance with global anti-money laundering standards and help build criminal justice and law enforcement capacity in the region.

It is important cross-border banking systems are open, secure and inclusive. The discussions this week in Brisbane may mark a return to a more resilient, re-banked Pacific Island community.

Global whale numbers are increasing for many species. While this is good news for conservation, the higher numbers coupled with dangers such as pollution, boating and climate change have caused an increase in whale deaths and strandings.

Some dead whales reach the shore, where their disposal poses a logistical challenge for authorities. Towing the carcass out to sea is one option, but it poses risks, such as the remains floating back to shore or into shipping channels. So understanding where whale bodies drift at sea is important.

That’s where our new research comes in. Last year, we tracked a whale carcass floating off the Queensland coast. We then compared this real-world data to that produced by computer modelling software typically used to help find boats lost at sea. We found the model accurately predicted where the carcass ended up.

Whale strandings are undoubtedly sad events. But with the help of science, the body can be disposed of in a way that doesn’t harm nature or people.

Big animal, big problem

When a whale dies at sea, it will initially sink but may refloat after a day or two, as gas develops in its intestines. If the carcass washes up on the beach, it must be dealt with.

Disposing of dead whales is complicated. Last century, authorities sought to blow up the carcasses to break them into smaller, more manageable pieces – a method, thankfully, which is no longer pursued.

In most cases these days, whale remains are buried in sand dunes or trucked to landfill.

Burying whale carcasses is not without challenges. They include the potential spread of diseases, groundwater contamination, and the attraction of scavengers which may impact local fauna and trigger public safety concerns.

Landfill disposal is also an imperfect solution. It requires an excavator and a truck to be brought to the beach – not always possible in very remote or inaccessible locations. To be feasible, a landfill should be located within a reasonable distance. And the loading and unloading of the carcass creates the potential for disease to spread.

The disposal of whale remains in landfills is also culturally controversial and raises ethical questions. Often, people have built up a positive connection with whales and want them buried respectfully.

Finally, the decomposition of organic matter in landfills produces climate damaging gases such as methane and carbon dioxide. It also removes important nutrients from the ocean.

Towing the carcass back out to sea may often be the best alternative. But it also comes with challenges – chiefly, preventing the carcass returning to shore or from becoming a hazard to boats. That’s why it can be useful to predict the movement of deceased whales adrift at sea.

The drift of a whale carcass is influenced by several factors such as wind, waves, tides and currents. Decomposition rates also play a role, and this can be affected by sun exposure, water temperature and scavengers.

A high-tech investigation

Our study involved a dead whale floating towards Queensland’s Sunshine Coast in July last year. The remains were identified as a 14-metre long female humpback, likely killed by a ship strike. The remains provided an opportunity to test and develop a prediction method for the whale drift trajectory.

The whale remains were disposed of about 30 kilometres offshore, close to the southward-moving East Australian Current. We then attached a satellite transmitter to the carcass, which provided information about the position of the whale remains every few minutes.

We tracked the whale remains for a week until we lost the signal – presumably because the carcass sank. We found the remains drifted towards the north – which was unexpected, given the prevailing current flowed in the opposite direction. We were also surprised that the remains travelled more than 150 kilometres.

The next step was to compare the real-world results against a computer simulation, to see how accurately the software predicted the path of the whale drift. Using search and rescue software known as SARMAP – designed to find various types of vessels lost at sea – we simulated the movement of the whale remains over the same period we tracked the carcass.

And the results? We found a simulation of a capsized skiff gave the best match for the actual path of the whale. It travelled in the same direction as the whale remains, within a few kilometres. We suspect this is because the objects are similar in terms of size and exposure above the sea surface.

The finding showed the forecasting of where whale remains might end up at sea is possible with surprisingly high accuracy.

Doing disposal well

Simulating the drift of a whale carcass towed to sea would reduce the risk of it being washed back ashore and help determine the best possible release location.

This would allow for more deceased whales to be returned to sea, where their remains play an important role in the marine ecosystem. The deep sea is generally deprived of nutrients, meaning a sunken whale carcass can be the only available food for many marine creatures.

Offshore disposal can be an ethical, cost-effective and safe option if managed well. To achieve this, we need better collaboration between local authorities, scientists and coastguards.

If you feel like you’re paying a lot for your child’s private school education, that’s because you probably are.

When we look at the international data, we see Australian households are contributing a lot more to their children’s education than other countries in the OECD.

Why is this happening? And why is it a problem?

What is the data?

I looked at the most recent OECD data on education (released in September 2023). This shows us how much private sources, including households, contribute to the costs of school education.

While the data does not specify which type of education (government, independent or Catholic), the OECD’s notes on how this data is collected refer to “private schooling”.

The analysis looks at primary and “upper secondary” school. In Australia, we generally understand this to be years 11 and 12.

For primary school, the OECD data shows “private spending” on education. This includes both households and sources such as companies and non-profit organisations. For upper secondary school, the OECD data shows household spending.

What do Australians spend compared to the rest of the world?

On average, private sources contribute 10% to primary education across the OECD. But in Australia, they contribute 20%. This makes Australia the fourth highest out of 40 countries.

In upper secondary school, on average, OECD households provide 9% of the total funding for school education.

But in Australia, households provide 21.4% of the total funding for these years. The only other countries with a slightly higher proportion are Hungary and Türkiye. The United Kingdom provides about 16% and New Zealand provides 6.5%. In Finland it is only 0.4%.

Why is this?

Australians contribute so much to the costs of their childrens’ education because so many students go to private fee-charging schools. This proportion is much higher than other OECD countries.

According to the Australian Bureau of Statistics, about 36% of Australian students go to non-government private schools with 64% going to public schools.

But enrolment significantly differs between primary and secondary schools. For primary, almost 69% of students are enrolled in public schools. For high school, this shrinks to 58%.

We also know tuition fees for private schools are increasing. For example, this year they have risen to almost A$50,000 per year per child in the senior years at the most expensive schools in Sydney.

We are seeing this “user-pays” mentality in public education, with parents being asked to donate funds for things such as school facilities and resources, as well as rising costs for basic items such as uniforms.

Why does this matter?

In Australia, private schools receive government funding without any regulation of how much they charge or how they enrol students. This is unusual in world terms.

In most OECD countries, if private schools receive government funds they are not allowed to charge any tuition fees.

If a private school can charge high fees, this can act as a barrier for some students. It means high-fee schools in Australia overwhelmingly enrol students from wealthy families. Researchers describe taking the students who come from the wealthiest backgrounds as “cream skimming”.

This means schools maximise their image by having students from high socioeconomic backgrounds without needing to improve their educational quality. As my 2017 research has shown, a key factor for parents choosing a school is who their child’s peers will be. Wealthy families tend to choose schools with children from similar backgrounds.

What can we do instead?

International research shows high-performing school systems are also equitable systems. This means they provide good quality education for the broad majority of students (not only those who can afford to pay).

From these figures, we can see how Australian households contribute far more towards school education than many other OECD countries. Beyond the individual pressure on families, this has an impact on how fair our system is and how well it provides for all students.

We know some other countries do not allow private schools to receive government funds and set their own fees. While this debate would be a controversial one, it does suggest we need to have a serious conversation about how private school fees are regulated in Australia.

Chappell Roan is on a steep rise to fame.

You may have encountered her current hit Good Luck, Babe! on the radio, at cafés or out in bars and clubs. If not, the song is a must-add to your favourite playlist.

Good Luck, Babe! is an upbeat, contemporary pop track with clear influences of 1980s pop-synth. Roan’s vocals soar across the track and offer a nostalgic recall of Kate Bush’s ethereal power and pitch.

Roan is gifted with an impressive vocal range and her lyrics paint a vivid array of images, people and places. Her 2023 album, The Rise and Fall of a Midwest Princess, is described by Pitchfork as “a bold and uproarious pop project stitched with stories about discovering love, sex, and oneself in a new place”.

Roan moved from small city Willard, Missouri, to Los Angeles upon signing with a record label in 2018. Living in California, she started to come to terms with her queerness.

Somewhere in the process of exploring queer identity and community, while dwelling in queer performance spaces (likely bars and clubs), Roan has emerged as a drag artist. In interviews, she speaks of the influences of drag on her visual and musical aesthetic, alongside fashion, theatre and other cultural forms.

But can a cis woman be a drag queen?

Traditions of cross-dressing in drag

A mainstream understanding of drag is informed by traditional acts of cross-dressing from one’s assigned birth gender: those born male become drag queens; those born female become drag kings.

In such a formula, the act functions by the audience having a clear, pre-existing awareness that the performer’s out-of-drag gender identity does not align with their onstage performance. Transgression, irony and humour ensues.

Often in drag acts, gender stereotypes are exaggerated to breaking point. Camp aesthetics can influence a subversion of beauty and aesthetic appeal in favour of embracing the trashy, ugly or gritty.

Drag might also function in the reverse: performers appear so attractive as to disturb a fixed sense of sexuality and desire among audiences. If you haven’t yet felt sexually confused at a drag show, I encourage you to see more and diverse examples.

Drag seeks to break down stereotypes of gender, sexuality and desire by holding space for multiple identities – real, performed, imagined – to simultaneously clash and coexist.

It’s a fabulously messy affair. It also does not necessarily rely on an act of cross-dressing from one’s assigned birth gender, or from any gender with which we identify.

Roan is a useful example of this point. Her drag leans into hyper femininity, at times toying with beauty ideals and elements of “ugliness” and trash. She performs with beautifully painted, soft facial and physical features and couples the visuals with hyper feminine movement. But you’ll notice a cigarette butt caught in her hair, or she’s wearing a massive nose prosthetic, or all parts of her visible skin are painted a deathly grey.

While Roan’s drag celebrates and plays up femininity and feminine beauty, she firmly holds a middle finger up at those same societal ideals and expectations.

Queer utopias and performance

With Pink Pony Club, Roan traces for us a process of coming out.

She sings:

I know you wanted me to stay

But I can’t ignore the crazy visions of me in LA
And I heard that there’s a special place
Where boys and girls can all be queens every single day.

The music video is set in what feels like a Midwest dive bar with Roan taking the stage to perform her song.

There are flashes of a queerly utopic alternative to the oppressively drab dive bar setting: leather daddies fill the dance floor, glitter falls from the ceiling, and drag queens Pork Chop and Meatball – icons of American drag – take the stage with Roan.

But it all ultimately falls away by the end of the song. The inspiration for the performer, while stirring, is only fleeting.

Queer performance scholars have written widely on the utopic potentiality of performance: the concept of alternative, “better” worlds emerging and converging on the horizon of performance. These offer a breathing space, however fleeting, away from the stultifying and oppressive real world that awaits performers and audiences outside of venues.

Conjuring and enacting such utopias is a survival strategy for queer people and other marginalised individuals, especially those craving the relief of alternative worlds and improved possible futures that deny the homophobic and transphobic everyday realities that surround us.

It is the same kind of momentary escape Roan explores in Pink Pony Club.

Expanding the world of drag

Roan is also known to enact spiritual beings such as fairies and sprites.

Here is yet another potential of drag: the embodiment of non-gendered spiritual and ethereal beings, aliens, monsters and creatures, which move beyond obsessions of the gendered body.

The power of drag in freeing individuals to temporarily inhabit alternative and exaggerated genders and sexualities – even species – challenges rigid societal beliefs and expectations. Drag offers an opening, “where boys and girls can all be queens every single day”.

Drag can be a performance of the opposite gender, but it can also hold space for diverse performances of gender to be explored. Where all those living within, in-between and beyond the gender binary can engage in playful and powerful imaginative acts that offer a momentary escape into the utopic and euphoric.

There is a lot of good in Housing Minister Chris Bishop’s new housing policy – especially in relation to mixed-use developments and intensification along transit corridors. But he has also proposed the abolition of minimum floor area and balcony requirements.

Will removing minimum dwelling sizes result in poor quality housing? The short answer is yes.

The minister has justified the minimum requirements by arguing any apartment, regardless of the size, will be bigger than a car or an emergency motel room.

Of course, he’s right about this. For those vulnerable to homelessness and poor housing – the poor, immigrants, pensioners, students and ex-prisoners, for example – a warm, dry shelter is vital. Anything is better than nothing for those without.

But there are risks to removing size regulations, even when it is meant to help solve New Zealand’s long-running housing crisis.

Small can work

Small does not necessarily mean bad. As the United Nations has noted, smaller units are often more sustainable. Other factors also determine the quality of living spaces. Overcrowded conditions, for example, can make a perfectly liveable space unviable.

There are numerous examples of high-quality small and micro-apartments – usually defined as being 14–32 square metres (sqm).

Take, for example, PKMN Architecture’s La Casa de Yolanda (Madrid, 50 sqm), Graham Hill’s Life Edited Apartment (SoHo, New York City, 39 sqm), Tsai Design’s Type Street Apartment (Richmond, Australia, 33 sqm), Proctor and Shaw’s Shoji Apartment (North London, 29 sqm), Brad Swartz’s Darlinghurst Apartment (Sydney, 27 sqm), Takeshi Hosaka’s Love2 House (Tokyo, 18 sqm), and A Little Design’s Taiwanese studio (Taipei, 17.6 sqm).

But these are all architect-designed and expensive. They often use generous room heights to create a sense of spaciousness. On top of that, many require owners to have sufficient strength to move walls or unfold furniture to transform a room from, say, a bedroom into a living room.

That could be ideal for the proverbial young professional, living much of their lives outside their flat, or for the short-term rental market. But it doesn’t work as well for families or older people.

The fear of shoebox apartments

A lack of minimum regulations can also cause unintended consequences.

In Melbourne, loose regulations resulted in “saddleback bedrooms” – where long thin light corridors (or “snorkels”) were built to access the required external windows. Bedrooms became reliant on borrowed light from other rooms.

Using borrowed light is now banned there, and snorkels have restrictions.

Auckland’s late 20th century shoebox apartments were built as small as 12 sqm – smaller than many of the motel rooms Bishop uses to justify abandoning minimum dwelling sizes.

These apartments led to the introduction of New Zealand’s minimum size requirements in the early 2000s.

Existing protections

New Zealand’s building code requires “adequate” openings for natural light, with illuminance of no less than 30 lux at floor level (for 75% of the time) – 30 lux being the equivalent of the light from 30 candles.

Openings must be transparent, suitably located and provide awareness of the outside.

Councils have different, but often similar, requirements for interior spaces. For example, Wellington’s District Plan’s Residential Design Guide requires dwellings get at least four hours sun in the main living room during the winter.

All habitable rooms must have natural light, rooms must be large enough for furniture, and circulation and windows must be placed for privacy.

The guide also requires that sleeping areas are shielded from external noises. These safeguards will mean there is a minimum quality for new apartments even if they are small. But it will also require political will from local government to ensure these safeguards are mantained.

Building for future risks

The real question, though, is whether the new policy will protect New Zealand long term – when the full wrath of climate change hits, or during any lockdown when the inevitable next pandemic emerges.

New Zealand needs homes offering longevity and resilience, as well as compassion for when we are most vulnerable. Cramped spaces are not great for mental well-being.

Housing rules need to be cognisant of infrastructure needs for a changing climate and decades of network neglect. This will be a challenge. Under the proposed policy, councils will not be able to refuse a development on the grounds that infrastructure costs are too high.

So yes, these changes will undoubtedly increase housing supply – but we need to ask if these builds are fit for purpose. There needs to be a balance between the very real need for more houses on one hand, and the need to preserve adequate dwelling standards on the other.

Violence against women has been declared a national crisis in Australia. National Cabinet convened its first ever meeting focused solely on the issue in May. Framed by its commitment to delivering the National Plan to End Violence against Women and Children, state and federal governments have committed to an array of different policies.

Sexual violence has, however, received less attention from the media and in political commentary of late. Research released by the Australian Institute of Criminology overnight provides stark evidence for why we must not let combating sexual violence fall off the national agenda.

Shockingly, the study found one in five (22.1%) participants had perpetrated one or more forms of sexual violence against another person since the age of 18. One in ten (9.9%) had done so in the past 12 months.

The prevalence of sexual violence

The study, by the Australian Institute of Criminology, is one of the largest community surveys conducted in Australia to focus on sexual violence perpetration. It surveyed 5,076 Australian residents aged 18–45 years about their use of various forms of sexual violence.

The survey defined sexual violence broadly to include sexual harassment and coercion, sexual assault and image-based sexual abuse.

Within sexual harassment and coercion, one in ten (10.2%) participants reported pressuring someone for dates or sex since the age of 18. One in 20 (6%) reported using emotional or psychological manipulation to get someone to participate in sexual activity (for example, telling them they were a prude if they didn’t have sex).

Just over 4% of respondents reported pressuring someone to take drugs or alcohol before requesting sexual activity. Another 4% reported pressuring someone to participate in unprotected sexual activity.

The most common forms of self-reported sexual assault were non-consensual kissing (6.6%) and non-consensual touching (6.4%). Meanwhile, 2.5% of participants reported having perpetrated sexual intercourse without a victim’s consent since the age of 18, while 2.4% said they had perpetrated stealthing (non-consensual removal of a condom during sex) or related behaviours.

Some 3.3% of participants said they had perpetrated image-based sexual abuse. This was defined as recording, sharing or threatening to share intimate, nude or sexual images or videos of someone else without their consent.

The gendered nature of sexual violence

The study finds the perpetration of sexual violence in Australia is highly gendered. Men were significantly more likely than women to report using all forms of sexual violence, including among perpetrators of multiple forms of these behaviours.

There are specific gender differences that stand out. Men were almost twice as likely to pressure someone into drug and alcohol use before asking for sex. Men were three times as likely as women to have blackmailed someone into sex in the 12 months prior to the survey.

Men were also three times more likely than women to perpetrate image-based sexual abuse. Men were significantly more likely than women to have perpetrated multiple forms of sexual violence.

Aligning with recent calls for a greater focus on serial perpetrators of violence, the study found that among participants who had used any form of sexual violence, 28.9% had used multiple forms since the age of 18.

While these figures are shocking, the report’s authors also warn they are likely to be an underestimate of the true prevalence of sexual violence in Australia. Perhaps unsurprisingly, more than 500 survey participants refused to provide information about their use of sexually violent behaviours.

Why focus on perpetrators?

Until now, our understanding of the nature and extent of sexual violence in Australia has relied on self-reported data from victims.

Latest results from the Personal Safety Survey show one in five adult women and one in 15 adult men have experienced sexual violence since the age of 15. While important, data from victims reveals little about the people who perpetrate sexual violence.

In recent years there have been calls for a greater understanding of who uses domestic, family and sexual violence. Research shows all forms of sexual violence are under-reported to police. Yet our understanding of perpetration relies almost solely on police and other justice system data.

There is a need for significantly improved understanding of who perpetrates sexual violence. This will inform effective responses, early intervention and prevention initiatives. This research partly addresses this gap.

What is needed now?

Perpetrator research is a difficult undertaking, particularly when asking about behaviours such as domestic, family and sexual violence. Social desirability bias means people may be unwilling to answer such questions truthfully for fear of making themselves look bad. Perpetrators can also deny or minimise their behaviours.

But we cannot effectively respond to and prevent what we do not measure. Sexual violence prevention programs and perpetrator interventions must be underpinned by an accurate understanding of the cohort being targeted and the nature of the abusive behaviours being used. This will maximise their likelihood of being effective in preventing future harm.

This study represents a step forward in furthering our understanding of sexual violence perpetration in Australia. However, we still need more detailed insights.

We need a better understanding of the characteristics of those who engage in multiple forms of sexual violence. We also need research on the nature of sexual violence within under-researched communities such as LGBTQIA+ and culturally and linguistically diverse communities.

This is crucial for informing the current and future work of federal, state and territory governments in developing effective interventions for people who use sexual violence.

Australia’s stable political and legal systems – and relatively resilient economy – make it an attractive place to do business.

But they also make it an alluring place for criminals to launder ill-gotten gains, heightened by the fact our anti-money laundering regulations are not up to par.

In a joint address to the National Press Club on Tuesday, Attorney-General Mark Dreyfus and Australian Transaction Reports and Analysis Centre (AUSTRAC) chief executive Brendan Thomas jointly announced the release of two new national risk assessments on money laundering and terrorism financing in Australia.

This followed the closure of a second round of consultation on anti-money laundering and counterterrorism financing reforms last month.

Dreyfus and Thomas painted a bleak picture of a country not only fraught with vulnerabilities to criminal activity and money laundering, but also lacking adequate controls to curb them.

What is money laundering?

Money laundering is the process of cleaning “dirty” money.

Dirty money typically refers to the proceeds of crime, which could include drug trafficking, tax fraud, corruption and bribery, or scams.

Money generated through crime typically can’t just be spent by the criminals involved. Simply depositing it in a bank would set off all kinds of alarms.

Criminals need to make it harder for authorities to trace it back to them, so they use a range of methods to launder it. Put simply, they attempt to make it seem like legitimate income.

This could be by buying real estate, funnelling funds through shell companies, depositing small amounts into various bank accounts, or gambling with it at casinos.

Today’s address highlighted that many of these money-laundering methods are often enabled by corrupt or unwitting professional service providers, including legal practitioners, accountants, consultants, trust and company service providers, financial advisers and real estate professionals.

These are known as “gatekeeper entities” because they act as intermediaries who can control access to certain services or information that criminals can use to launder money.

Regulations aren’t up to scratch

In Australia, these gatekeeper entities are not currently covered under the anti-money laundering and counter-terrorism financing regime, making us one of only a few countries neglecting this huge vulnerability.

Coincidentally, on Tuesday, the global anti-money laundering and counter-terrorism financing watchdog the Financial Action Taskforce (FATF) also released a report reviewing gatekeepers’ “technical compliance related to corruption”.

Australia, China, and the United States all scored 0% on requirements to cover gatekeeper sectors, putting all three at the bottom of global rankings.

According to the report, in our case this is largely because:

In Australia, these sectors are required to implement none of the preventive measures that have been required by the FATF Standards since 2003.

A recipe for criminal exploitation

AUSTRAC’s risk assessment ranked domestic real estate, luxury goods, and cash (as both transfer and store of value) as “very high risk” channels or sectors for money laundering.

Accountants, lawyers, precious metals, and legal structures were all ranked “high risk”. These sectors could be playing a role in better controlling money laundering in Australia. Instead, they are currently passive, and sometimes active, enablers.

In rankings of proceed-generating crime threats, illicit drugs, tax and revenue crime, and government-funded program fraud were identified as the highest-risk. The proceeds of these crimes are known to be laundered. Careful laundering can allow criminals to keep using that money with impunity, fueling further crimes.

Bring those two sets of risk ratings together, and it’s clear Australia has both highly profitable criminal activity and a range of sectors highly vulnerable to money laundering abuse. That is a recipe for criminal exploitation.

There’s an appetite for change

The national risk assessments are out at a useful time. Tranche II reforms to update Australia’s anti-money laundering and counter-terrorism financing measures are in progress. In the last budget, A$166.4 million was set aside to implement the necessary reforms.

Under these reforms, a wide range of gatekeeper businesses in Australia will be required to develop an anti-money laundering and counter-terrorism financing program. Organisational risks will need to be assessed. Suspicious transactions will need to be reported. Awareness and education about money laundering through these legal channels will undoubtedly result.

The national risk assessments were a significant undertaking by AUSTRAC. They provide an evidence-base for the money laundering and terrorism financing risks we face in Australia.

As noted by AUSTRAC chief executive Brendan Thomas, Australia’s strong business sector is appealing to both legitimate and illegitimate business. Criminals are good at exploiting weaknesses, so the controls to slow them must be stronger.

An effective anti-money laundering regime is the best tool we can have to control flows of dirty money. While we will never completely eradicate it, we can certainly do a better job of detecting, deterring, and preventing the abuse of legal channels in Australia.

Our government has had 17 years since passing the Anti-Money Laundering and Counter-Terrorism Financing Act to bring the legislation up to the minimum standards set by the global Financial Action Task Force. So far, it has failed to deliver. Not only does this leave gaping holes for criminals to exploit, but it also means we are not collecting data on suspicious transactions within these gatekeeper industries.

Since early 2023, the Northern Territory and federal governments have been trialling a range of social control measures in Alice Springs (Mparntwe) to address moral panics in relation to youth crime.

The initial focus was on reinstating restrictive alcohol laws in Aboriginal communities, then more police and funding for prisons, and now curfews.

Yesterday, the NT Police Commissioner announced a snap three-day curfew following violent incidents, including off-duty police officers being assaulted.

But there’s little evidence to suggest it will work, either to drive down violent behaviour or to protect the public.

Curfew fears realised

In January 2023, trailblazing Arrernte midwife Cherisse Buzzacott saw the writing on the wall. She said, “We fear curfews”. Cherisse grew up during the NT Intervention years and knows what it is like to be an Aboriginal young person surveilled by police and subject to racially discriminatory laws.

Barely a year on from her comments, these fears were realised. In March 2024, the NT government announced a two-week curfew to ban young people from the Alice Springs CBD between 6pm and 6am. This was then extended by a further week.

Following advice from the NT Police, the territory government granted powers under the Police Administration Act to declare 72-hour curfews when the police commissioner reasonably believes there is public disorder or a significant risk of it. The commissioner can also request an extension of up to seven days.

Unlike the previous curfew, the new legislation allows for criminal penalties. Non-compliance with curfew orders is a “strict liability” criminal offence, which means even if the person honestly believes they are complying, they will be criminalised. The maximum penalty is a fine of A$1,480.

The NT government suspended the Anti-Discriminatory Act 1992 to enable the enforcement of curfews. This raises a red flag about its potential discriminatory impacts, even though the laws are ostensibly neutral.

The North Australian Aboriginal Justice Association (NAAJA) has raised concerns about police targeting Aboriginal young people in the enforcement of curfews, and described the curfews as “racist lockdown laws”.

History of curfews, here and abroad

Curfews are not a new government strategy. They have been deployed for decades to restrict the movement and liberties of Aboriginal people in Australia. Curfews were enabled by the Aboriginal Protection Acts – a legislative regime that controlled and segregated Aboriginal people.

In the NT, Aboriginal people were barred from entering Alice Springs between sunset and sunrise from 1928 to 1964. In Western Australia, curfew laws were passed in 1905 that barred Noongar people from central Perth after 6pm. There were also 9pm curfews on Aboriginal reserves in Queensland.

More recently in Redfern and surrounding areas in Sydney in the 1960s and ‘70s, police enforced nightly 10pm curfews on Aboriginal people. The same strategy had been used for slaves across the colonies, including in the United States.

Do curfews increase safety?

The most rigorous studies in relation to curfews have been undertaken in relation to youth curfews in the US. One study in 1994 showed 77% of large US cities having a curfew policy, and another in 1997 indicated it was as high as 80%.

Studies of these curfews have repeatedly found that they do not reduce crime. US curfews have been imposed on the assumption that restricting young peoples’ hours in public will “limit their opportunities to commit crimes or become victims”, but this objective has not been realised.

A 2016 review of ten studies on the impact of youth curfews in the US since 1960 found they were ineffective in reducing criminal behaviour and victimisation among youth.

In fact, young people were slightly more likely to commit crime during the curfew hours, compared to the hours when the curfew was not imposed.

Similarly, victimisation rates were not affected by the curfew. A contemporaneous study of the tightening of Baltimore’s youth curfew laws found it “did not have the desired effect of reducing juvenile crime during curfew hours”, but did have the effect of increasing arrests of young people. Another review in 2018 found the basis for curfews lacked “empirical” evidence.

Studies in relation to particular offences, such as knife crimes, also found curfews did not have a significant impact.

There do not appear to be similar studies on whole-of-population curfews, which is occurring in relation to the Alice Springs curfew. This type of curfew appears unprecedented in its extension to adults.

However, it is likely to manifest in a similar way to the curfews that sought to control Aboriginal people. From the experience in Redfern, the overwhelming consequence was an increase in police charges, arrests and violence.

What are the risks?

In Alice Springs, there are risks for particular groups that are unable to comply with curfew orders. The NT has the highest homeless population in the country, and people who are unable to find shelter outside of the town are likely to be subject to law enforcement.

Young people who are in the child protection system are also likely to walk the streets at night due to neglect by state agencies, as exposed in the Royal Commission into the Protection and Detention of Children in the Northern Territory. In addition, people with mental health and trauma needs may be unable to comply with the curfew requirements.

The curfew approach has high risks for little proven gain. After almost 20 years of top-down punitive interventions in NT Aboriginal communities, since the NT Emergency Response was rolled out in 2007, it is time to critically reflect on this track record.

The response to the colonial curfews in Alice Springs in the early 20th century was to build Alice Springs town camps that would restrict Aboriginal movement into the CBD after hours. This new curfew policy is repeating a process that has not changed.

At a time when the NT police is facing intense scrutiny and accusations of a culture of racism, handing executive powers to the NT Police Commissioner to declare curfews is unlikely to improve community safety and may likely increase community tensions.

A popular wildlife park in Brisbane has announced it will no longer offer “koala holds”, prompting questions about whether other captive animal facilities should follow.

Koala handling has long been criticised by animal welfare advocates. They say koalas are naturally solitary, nocturnal animals that become stressed when placed in close proximity to humans – so hugging them is “completely unacceptable”.

I study stress in animals, particularly marsupials – and I can confirm koala cuddles are detrimental to these animals.

There’s a compelling evidenced-based argument for other zoos and wildlife parks to reassess their policies on koala handling. I would also argue this review should be extended to other human-animal interactions more broadly. The zoological industry should go further and call for the practice to be banned nationwide.

Research into koala handling and stress

The Lone Pine Koala Sanctuary ended koala cuddles on July 1. It denies animal welfare concerns prompted its decision.

Instead, the sanctuary says the move was triggered by “strong visitor feedback” from people wishing to spend more time with koalas, without necessarily holding them. Management says both local and international guests still want to get “up close”, just not so personal.

Regardless of the motivation, public attitudes to animal welfare are shifting around how animals should be treated, and whether endangered species such as koalas should be kept in captivity at all.

Research shows chronic stress in captivity can cause physiological problems such as weight loss, changes to the immune system, and decreased reproductive capacity.

Koalas naturally avoid humans in the wild. They see people and other animals as a threat.

The simple presence of tourists walking through their habitat can elevate a koala’s heart rate.

Levels of the stress hormone cortisol can increase both during and after handling sessions in adult koalas, although this stress response varies depending on gender and reproductive status.

Male koalas are more stressed to begin with. This may be because they are highly territorial. Interacting with people could disturb their sex drive, with unfortunate consequences for koala breeding programs.

Koalas are nocturnal in the wild, but in zoos they are displayed during daytime. This may disturb their sleep when they are on a break.

Humans also wear fragrances that could be irritating, given koalas have highly sensitive noses.

All these sources of stress add up over time. We know chronic stress has long-term effects on health and wellbeing in humans and animals. Some animals are particularly prone to stress in captivity.

Broader implications for wildlife in zoos

Australia’s Zoo & Aquarium Association says it strongly supports the Lone Pine Koala Sanctuary’s new position for koala experiences. In a statement, it said the decision

will address the desires of visitors to see koalas in their natural state while still providing the immersive, unforgettable, and educational experiences that drive conservation engagement in ZAA-accredited institutions.

Caring for animals goes beyond providing food, water and a place to live. It taps into the deeper cognitive and emotional dimensions of how wildlife relate to their environment, especially the presence of humans.

Accredited zoos employ well-trained and skilled professionals to take care of animals. But not all animals are suited to interactions with visitors.

For example, a study on cheetahs in captivity found stress from handling and other human interactions was linked to lower reproductive rates and higher instances of illness.

All animals can experience some form of discomfort when handled. However, zoo animals are handled by trained professionals and provided appropriate rest breaks.

Extra care should be taken when handling birds such as parrots and raptors, as they also suffer from stress and behavioural disruptions due to handling.

Reptiles, including snakes and lizards, are more resilient but stress can disrupt thermoregulation and feeding. Amphibians such as frogs and salamanders are particularly sensitive due to their permeable skin, making handling more risky. Large carnivores and primates can experience psychological stress and behavioural issues from human interactions.

Alternative approaches

Zoos balance animal welfare against the need to engage the public. People want to interact with wildlife and there are many ways to achieve this, aside from visitors handling the animals. They include:

Observation-based experiences: zoos can offer guided tours and observation experiences where visitors can learn about animals in a more natural setting. This can include watching feeding sessions, enrichment activities and natural behaviours from a safe distance.

Interactive technology: augmented reality and virtual reality can provide immersive experiences that allow visitors to feel close to the animals without physical interaction. These technologies can simulate close encounters and provide educational content in a captivating manner.

Educational programs: zoos can enhance educational programs by incorporating more talks, demonstrations and interactive exhibits that focus on animal behaviour, conservation and the importance of respecting wildlife.

Volunteer opportunities: For those keen on a more hands-on experience, zoos can offer volunteer programs where participants can assist with habitat maintenance, animal enrichment and other behind-the-scenes activities that do not involve direct handling.

A big act to follow

One wildlife park’s decision to cease offering koala cuddles is a huge step in the right direction. It reflects a growing recognition of the need to prioritise animal welfare in a zoo setting.

Research consistently shows handling can cause significant stress to koalas and other wildlife, leading to adverse health effects. As stewards of conservation and education, zoos must balance visitor engagement with the ethical treatment of animals.

By adopting alternative approaches that minimise stress and promote natural behaviours, zoos can continue to educate the public and foster a deeper appreciation for wildlife – without compromising the wellbeing of the animals in their care.

Balancing tourism and animal welfare involves species-specific handling policies, proper training, and alternative engagement methods. Educating visitors about the importance of animal welfare can help reduce the demand for direct handling. While outright bans may not be necessary, minimising handling and employing ethical practices are crucial for ensuring animal welfare in captivity.

Australian celebrity cook Maggie Beer has long been an advocate for better quality meals in aged care. It led her to a four-month immersion in an aged care residence with the goal of transforming the meals and dining experiences there.

She and the producers of a three-part ABC documentary series, Maggie Beer’s Big Mission, which will premiere and stream from tonight, hope it will spark nationwide change.

The program was motivated by the high levels of neglect, malnutrition and social isolation identified by the Royal Commission into Aged Care Quality and Safety and a new rights-based Aged Care Act, which is currently being drafted.

Our team of speech pathologists, occupational therapists, dietitians, and researchers had a behind-the-scenes view of this “social experiment”. We helped evaluate its impact for residents and staff, to understand how other centres could use the same evidence-based approach.

Serving up choice and dignity in aged care – how meals are enjoyed is about more than what’s on the plate

Turning problems into solutions

The experiment took place a section of Meath Care’s Dr Mary Surveyor Centre in Kingsley, Western Australia, home to 44 residents.

At the start of the experiment 78% of residents evaluated were at risk of malnutrition or malnourished and 46% experienced depression. These figures are confronting yet not unusual based on previous studies and the Royal Commission estimate that 68% of Australians in residential aged care are malnourished or at risk of becoming so.

Maggie, aged 79, and her team of experts worked alongside staff and residents to design and implement a new model of mealtime care. This included:

• making meals more nourishing, flavoursome and visually appealing, with increased protein and fresh ingredients
• giving residents variety, choice and independence with a buffet-style offering
• involving residents in mealtime roles such as setting tables and restocking supplies
• creating a calmer, more dignified and social mealtime experience.

These sound like simple changes, but they can be challenging given budget adjustments, physical renovations and staff training and support. Resident and staff responses revealed a pathway to better nutrition and socially engaging care.

Here’s what the experiment showed can work:

1. Influential leadership

Maggie Beer has championed this issue, modelling humility and openness to learning. She fronted a team with a shared vision – “to make every mouthful count”.

She shows leaders can work alongside staff to understand the challenges and identify solutions, share accountability for change and celebrate success.

2. Questioning habits and the status quo

Just because meals have always been prepared or served in a certain way, doesn’t mean it’s the best way. Standards of care can be re-imagined and the evidence translated into resident-centred care.

What the program shows is small changes (like making one’s own fresh toast, served hot) can make a difference to choice and mealtime enjoyment.

It also means being flexible enough for different needs and safety considerations. For example, texture modified diets – food textures that improve safety for residents with swallowing difficulties – can be hard to get right. But that doesn’t mean change can’t happen. As one senior staff member noted, there is dignity in having the same meal as others:

Traditionally, the aged care puree diet would be yesterday’s food or batch prepared and put in the freezer. Now, having the same food cooked out of the same oven and then modified, for me, I think that runs to dignity.

3. Experiencing change

Maggie and her team provided more than 175 hours of training to staff. Topics included nutrition, swallowing, oral health, as well as leadership and person-centred care.

Coaching, mentorship and support in the kitchen and dining room was also provided.

Staff valued seeing, feeling and experiencing the benefits that flowed from new ways of facilitating residents’ choice and independence during meals. This built momentum and shifted mindsets. As one care worker said:

[…] you don’t realise how independent some people [residents] can be. They’ve never had the opportunity. They never cease to amaze me about what they can do if they’re given the opportunity.

4. Harnessing mealtime expertise

We know there is not enough access to allied health care in residential settings. This means residents don’t always get the support of occupational therapists, dietitians or speech pathologists when they need it.

The series shows bringing allied health expertise into the dining room can enhance residents’ health and wellbeing. Mealtime interventions – making therapeutic changes such as suitable eating implements, modified diets and textures or assistance with eating in a real-life context – helps care staff see the residents’ potential.

5. Keeping the model going

The program and the changes it brought were not without tension. But these were viewed as a positive sign of change.

As part of the recipe for change it is important to set staff up for success, providing the knowledge, tools (such as self-assessments and mealtime auditing) and ongoing support to sustain change and recognise if the quality of meals and dining experiences are slipping. As one team leader said:

I’m probably most proud of the way the staff have been able to adapt […] I’m proud of how they’ve stood up and said, oh, hang on a minute, we’ve all learned that this is not a really good way of doing it.

Will it work on a bigger scale?

This real-life experiment successsfully improved residents’ appetite, mealtime satisfaction and mood, with full results being prepared for publication.

The standard of mealtime care was lifted with many residents enjoying increased choice and independence, as one resident said:

I can see what I’m getting, and I can get what I want.

It is a model that can be adopted nationwide if aged care organisations invest in the vision, training and ongoing support for staff to make the necessary change.

Tools have been created for other aged care organisations to replicate the model, considering self-service options for example.

We all have a role to play in supporting this mission and lifting the standard of care – ensuring residents are nourished, socially engaged and active partners in their care.

Any night now, a “new star” or nova will appear in the night sky. While it won’t set the sky ablaze, it’s a special opportunity to see a rare event that’s usually difficult to predict in advance.

The star in question is T Coronae Borealis (T CrB, pronounced “T Cor Bor”). It lies in the constellation of the northern crown, prominent in the Northern Hemisphere but also visible in the northern sky from Australia and Aotearoa New Zealand over the next few months.

Most of the time T CrB, which is 3,000 light years away, is much too faint to be seen. But once every 80 years or so, it brightly erupts.

A brand new star suddenly seems to appear, although not for long. Just a few nights later it will have rapidly faded, disappearing back into the darkness.

A burst of life

During the prime of their lives, stars are powered by nuclear fusion reactions deep inside their cores. Most commonly, hydrogen is turned into helium creating enough energy to keep the star stable and shining for billions of years.

But T CrB is well past its prime and is now a stellar remnant known as a white dwarf. Its internal nuclear fire has been quenched, allowing gravity to dramatically compress the dead star.

T CrB also has a stellar companion – a red giant that has puffed up as it enters old age. The white dwarf mops up the swollen red giant’s gas, and this forms what’s known as an accretion disc around the dead star.

The matter keeps piling up on a star that’s already compressed to its limit, forcing a continual rise in pressure and temperature. Conditions become so extreme, they mimic what once would’ve been found inside the star’s core. Its surface ignites in a runaway thermonuclear reaction.

When this happens, the energy released makes T CrB shine 1,500 times brighter than usual. Here on Earth, it briefly appears in the night sky. With this dramatic reset, the star has then expelled the gas and the cycle can begin all over again.

How do we know it’s due?

T CrB is the brightest of a rare class of recurrent novae that repeat within a hundred years – a time scale that allows astronomers to detect their recurrent nature.

Only ten recurrent novae are currently known, although more novae may be recurrent – just on much greater timescales that aren’t as easily tracked.

The earliest known date of T CrB erupting is from the year 1217, based on observations recorded in a medieval monastic chronicle. It’s remarkable that astronomers can now predict its eruptions so precisely as long as the nova follows its usual pattern.

The star’s two most recent eruptions – in 1866 and 1946 – showed the exact same features. About ten years prior to the eruption, T CrB’s brightness increased a little (known as a high state) followed by a short fading or dip about a year out from the explosion.

T CrB entered its high state in 2015 and the pre-eruption dip was spotted in March 2023, setting astronomers on alert. What causes these phenomena are just some of the current mysteries surrounding T CrB.

How can I see it?

Start stargazing now! It’s a good idea to get used to seeing Corona Borealis as it is now, so that you get the full impact of the “new” star.

Corona Borealis currently reaches its best observing position (known as a meridian transit) around 8:30pm to 9pm local time across Australia and Aotearoa. The farther north you are located, the higher the constellation will be in the sky.

The nova is expected to be a reasonable brightness (magnitude 2.5): about as bright as Imai (Delta Crucis), the fourth brightest star in the Southern Cross. So it will be easy to see even from a city location, if you know where to look.

We won’t have much time

We won’t have long once it goes off. The maximum brightness will only last a few hours; within a week T CrB will have faded and you’ll need binoculars to see it.

It almost certainly will be an amateur astronomer that alerts the professional community to the moment when T CrB outbursts.

These dedicated and knowledgeable people routinely monitor stars from their backyards on the chance of “what if” and therefore fill an important gap in night sky observations.

The American Association of Variable Star Observing (AAVSO) has a log of over 270,000 submitted observations on T CrB alone. Amateur astronomers are collaborating here and around the world to continually monitor T CrB for the first signs of eruption.

Hopefully the nova will erupt as expected sometime before October, because after that Corona Borealis leaves our evening sky in the Southern Hemisphere.

After two COVID-affected Olympic Games in Tokyo in 2021 (summer) and Beijing in 2022 (winter), the Paris Games should see a return to normalcy.

With no health-related restrictions, tourists and spectators will be there in droves. Athletes will be able to mix in the city rather than stay locked down in the Olympic Village.

The City of Lights promises plenty to do and a buzzing atmosphere. There will be 32 sports and 329 events taking place, several large fan zones and numerous tourist sites in this enchanting and famous world-class city.

Hospitality is guaranteed to be in full swing, accentuated by French “joi de vivre”.

So, what lessons can Brisbane learn eight years ahead of hosting the 2032 Games?

Getting ready for Brisbane

Brisbane will have its challenges trying to emulate Paris but has the potential to bring a distinctive “Aussie slant” to the Olympics.

Here are some of the changes that may take place.

New Sports: Breakdancing will be a new addition in Paris. The International Olympic Committee (IOC) sets out policies and guidelines that determine which sports can be added to the portfolio.

However, a host city’s organising committee can recommend new sports to be approved for their games. Under this arrangement, the Los Angeles games added squash, flag football, lacrosse, cricket and baseball/softball to the existing 27 core sports.

Brisbane can have the same influence and is likely to keep most of the 2028 additions and may look to add sports such as surf lifesaving, coastal rowing, netball, lawn bowls or even pickleball.

An Enhanced Spectator Experience: About 10 million tickets will be available in Paris for spectators who have been provided with designated mobile applications and (online) information links.

There are lots of special hospitality options including sites at Nations Park, Champions Park as well as 33 “party houses” the public can visit either free or at a modest cost – usually a lot less than sport tickets.

Most of these venues have been set up by countries’ National Olympic Committees but there are others like Pride House and one called the AICO House for Olympic Collectors.

Surprisingly, Australia does not have an Olympic House, an omission that could change for future Olympics.

Tourism Boost: The 2024 Paris games are set to increase tourism spending by up to A$6.5 billion. Likewise, the Brisbane games can deliver a similar boost for Australia – currently ranked the fifth best tourism destination in the world.

TV/Media Initiatives: There will be unprecedented television, streaming and media coverage of the Paris games around the globe. It will likely set records as the most viewed Olympics of all time. This could expand further by 2032 with creative new platforms and ways to follow the events.

Opening Ceremonies: Paris is planning unique opening ceremonies, initially using the Seine River for a 90+ boat cavalcade with up to 300,000 spectators able to watch. It will then move to the Trocadero where the remaining elements of the Olympic protocol take place.

Depending on how well this is received, the Brisbane River is a possibility to be used in a similar vein.

Security, Terrorism, Cyber Hacking, Water Pollution, Social and Political Unrest: How will the French handle a host of key issues which threaten to disrupt or ruin the event?

As France sits in the busy European corridor, and with nearby international problems in the Ukraine and Gaza, there could be major security issues.

Even though Australia is a remote island continent far removed from current hot spots, new problems could emerge by 2032.

Extreme Weather Conditions: Extreme heat, which has been predicted for Paris in a Rings of Fire Report, can lead to schedule problems and athlete health concerns. In contrast, the Brisbane games will take place in the Australian winter months, which are not traditionally affected by extremely hot temperatures, excessive rain, storms or cyclones.

Doping Issues and Controversies: Although there will be strict drug testing in Paris, athletes may still get caught cheating and consequently banned. This might even occur post-games as test protocols get more sophisticated.

A current controversy highlights this – Chinese athletes who were not banned at the Tokyo 2021 games by the World Anti-Doping Agency after testing positive before those games commenced.

Doping remains a thorn in the side for upcoming Olympics, including Brisbane in 2032.

Banned Olympic Countries and Cyber Hacking Retaliation: For Paris, Russia and Belarus cannot send their national teams except as individual neutral athletes (with no flags or marching in the ceremonies).

There are strong indications Russia may retaliate and engage in cyber hacking at the 2024 games.

What will be the case a long eight years from now? Could there still be bans on certain nations and cyber issues Brisbane organisers will need to deal with?

Iconic Venues with Tradition and History: Paris is using many iconic venues such as beach volleyball being held near the Eiffel Tower and equestrian at the Palace of Versailles.

Brisbane can try to create an Aussie theme emphasising a “sun and beach culture”. With both the Gold Coast and the Sunshine Coast serving as regional sites, the Sunshine State can promote this as a distinctive feature.

Aussie Success at the Summer Games: As a very successful Olympic nation (11th overall), predictions are for Australia to finish fifth on the medal table in Paris with around 50 medals.

Host nations improve in the vast majority of cases on previous games so by 2032 Australia could reach third place, tying the best ever placement achieved in Melbourne in 1956.

The current state of play for the Brisbane games

Planning is well under way for the 2032 games with the establishment of the Brisbane Organising Committee for the 2032 Olympic and Paralympic Games as well as the Brisbane 2032 Coordination Office. The vast majority of sport venues, the four athletes’ villages and transport upgrades have also been confirmed.

One hiccup is a disagreement over the decision not to build a new state-of-the-art stadium, and instead use existing ones. This decision was made by the Queensland government and endorsed by the IOC and the AOC.

An October 2024 state election could see this situation change as several proponents are keen to have a new stadium.

Most Queenslanders remain in favour of hosting the games but others have expressed concerns about the event’s impact on finances, infrastructure and daily life.

With eight years to go, there is plenty of time to sort out issues and also take lessons from the Paris games, as well as Los Angeles four years later.

Both Melbourne in 1956 (often referred to as the “Friendly Games”) and Sydney in 2000 (labelled the best Games ever by then IOC President Juan Samaranch) hosted extremely successful Olympics.

Brisbane should be aiming to follow suit.

Electric vehicles are an increasingly common sight on Australian roads. Each one cuts carbon emissions by half compared to fossil fuel vehicles, but increases household electricity use by 50%.

This extra electricity demand could be a major strain on the grid unless the charging of vehicles is coordinated. But the large batteries in electric vehicles could also be enlisted to discharge power to the power grid when needed. The average electric vehicle battery stores more than two days worth of household electricity, so this could have a big effect.

Over the past five years I’ve been a part of the Realising Electric Vehicle-to-grid Services (REVS) project to establish the technology to do this in Australia.

This project utilised 50 ACT government-owned Nissan LEAF electric vehicles and chargers across Canberra. Another project partner, JET Charge, set up the chargers to monitor the state of the electricity system. Electricity retailer ActewAGL programmed the chargers to discharge short bursts of power to the national grid on the rare occasions it rapidly loses power generation.

Such a grid emergency happened on February 13 this year. A storm blew over high-voltage transmission towers west of Melbourne, triggering the disconnection of Loy Yang coal power station and two wind farms.

The results of this real-world test prove a vehicle-to-grid system can work. The vehicles quickly discharged power when the generators disconnected. However, the results also highlight the need to be smarter about how all electric vehicles charge, especially during such emergencies.

Vehicle discharging to the rescue

At the time of the event, around 1pm, 16 electric vehicles from our fleet were plugged in to chargers at six properties across Canberra. Four vehicles were charging, 12 were idle.

When the power generators disconnected, that created an immediate shortage of power supply in the national grid.

The chart shows how the 16 vehicle-to-grid-enabled vehicles responded. They quickly switched from charging to discharging power into the grid, as our system set them up to do.

In total, the 16 vehicles provided 107kW of support to the grid. This was the first time in the world such a vehicle-to-grid response to a grid emergency has been demonstrated.

For context, we would need only 105,000 vehicles providing such a response to fully cover the typical spare capacity in the NSW and ACT system used to balance supply and demand when an unexpected event occurs. We already have more than 200,000 electric vehicles on Australian roads. Of these, 98,436 new electric vehicles were sold last year and more than 40,000 in the past five months.

The REVS vehicles kept discharging for ten minutes. This is in line with the electricity market rules, which specify that devices should respond for ten minutes.

What came next is a warning that more needs to be done to manage electric vehicle charging.

Timing makes all the difference

The growing demand for vehicle charging raises the question: how can we manage charging to meet the needs of both drivers and the electricity system?

Part of the answer is to manage the rate and timing of charging. The grid won’t be able to cope with everyone charging their vehicles at the same time when they get home of an evening.

And grid security and disconnected customers don’t benefit from vehicles charging when there’s not enough power to supply all customers.

In February, once the vehicles had discharged power for ten minutes, nine vehicles started charging. This is because their default behaviour is to charge when their batteries are below a certain level. It’s the last thing the power system needs while trying to stabilise.

The six vehicles that switched to an idle state after ten minutes must have still had enough energy in their batteries. That one vehicle kept discharging for ten more minutes was due to a software bug.

What’s more, when we looked at data from other ACT government vehicles parked in these properties, we found 23 were charging throughout the event. Again this directly obstructs power system recovery.

There would have been absolutely no inconvenience or cost for the vehicles to delay charging for an hour or two.

Stopping 6,000 vehicles charging (at 5kW) could have kept the power on for the 90,000 customers whose power was cut that afternoon. However, electric vehicles in Australia have not been set up to respond to grid emergencies.

Securing the grid in an all-electric future

Electrifying our homes’ stoves, vehicles, space and water heaters is essential for the transition to a zero-emissions future. But we need to better design how all these devices interact with the electricity system that powers them.

Devices that aren’t needed urgently should not use power when the grid is stressed. Instead, they should use power when there is ample renewable supply.

Our results show vehicle-to-grid can be a powerful contributor to power system security. At the same time, they highlight the need to make better use of any available flexibility in the timing of when certain appliances use power.

Electric vehicle charging is the largest opportunity but electric hot water heaters could also make a big contribution without causing inconvenience. These vehicles and heaters offer exceptionally efficient and effective ways to create a more resilient and clean electricity system.

For vehicles, our related research indicates that better engaging the auto industry is a crucial missing link. Car salespeople and fleet managers introduce drivers to electric vehicles and shape their expectations of how these vehicles are to be used.

Approaching the issue from the auto side, we could update the Australian Design Rules to require that vehicle manufacturers make electric vehicles stop charging automatically during a grid emergency (with a driver override for urgent charging).

For at least 3,500 years, dingoes have been Australia’s top terrestrial predator. And in current times, they are one of the continent’s most iconic but controversial animals. Dingoes hold significant cultural value, including a long connection with Aboriginal and Torres Strait Islander peoples.

Dingoes also play a crucial ecological role, helping to regulate the population of native animals such as kangaroos, and feral animals such as rabbits and cats.

However, while dingoes are protected in some national parks, in many areas they are persecuted and commonly killed.

Our ability to trace the origins, arrival and history of the dingo has been limited by potential interbreeding with introduced modern dog breeds since the British invasion.

Our team used ancient DNA sourced from dingo bones predating the European invasion of Australia’s east and west coasts to help answer all of these questions. Our study is now published in the Proceedings of the National Academy of Sciences.

Turning back the clock

To circumvent the ambiguity introduced by any potential interbreeding between dingoes and modern dog breeds, our team collected 42 ancient dingo skeletal remains. Our collection included dingoes ranging in age from 400 to 2,746 years from all around Australia.

We successfully extracted ancient DNA from these skeletal remains, effectively rolling back the clock to take a rare glimpse into the genetic makeup of dingoes in the past, free from any modern dog interbreeding.

By examining these ancient genomes, we can trace the lineage of dingoes back thousands of years and understand how their populations have changed over time.

Two groups of dingoes

Modern dingoes are classified today into two major geographical groups, East and West.

How did this grouping arise? One theory has been that the groups were separated by the dingo fence built in the late 19th to mid-20th century. It divides the southeast of the continent from the rest.

However, our study of ancient genomes shows that genetic differences between the East and West groups emerged well before the European invasion.

This suggests dingoes adapted to their environments and formed separate populations in different regions of Australia thousands of years ago, highlighting the resilience and adaptability of dingoes in various Australian landscapes.

An unlikely link with New Guinea

To our surprise, we uncovered an unlikely genetic connection between ancient dingoes from coastal New South Wales and the endangered New Guinea singing dogs.

New Guinea singing dogs are wild roaming dogs, currently only found in small numbers in New Guinea’s highlands. They are known for their melodious howls. They are the closest known relative of dingoes, and look similar to them.

Our study suggests at least one wave of migration between New Guinea singing dogs and dingoes roughly 2,500 years ago, at least a thousand years after dingoes arrived in Australia.

Given the length of the sea crossing from New Guinea to Australia, dingoes must have moved with human populations as companion animals, likely during trade.

This genetic link with New Guinea singing dogs confirms evidence for regional movement of humans provided by recent finds of pottery of similar age from New South Wales and far north Queensland.

Little mixing with modern dogs

Contrary to previous concerns, our tests showed modern dingoes have retained much of their ancient genetic makeup, with little genomic ancestry from post-colonial interbreeding with domestic dog breeds.

This finding highlights the importance of populations protected in national parks, such as the iconic “Wongari” population of K’gari (briefly named Fraser Island in post-colonial times), which was represented by three individuals in our study. The ongoing culling of dingoes in much of Australia makes this protection even more important.

By providing a clearer understanding of the genetic heritage and population history of dingoes, our research supports efforts to preserve the ecological role and cultural significance of these animals in Australia.

Our study confirms that modern dingoes remain genetically distinct and preserve their ancient heritage. They are crucial for the conservation and management of dingo populations.

A healthy diet protects us against a number of chronic diseases, including heart disease, diabetes and cancer.

From early childhood, we receive an abundance of information about how we should eat to be healthy and reduce our risk of disease. And most people have a broad understanding of what healthy eating looks like.

But this knowledge doesn’t always result in healthier eating.

In our new research, we set out to learn more about why people eat the way they do – and what prevents them from eating better. Lack of time was a major barrier to cooking and eating healthier foods.

How do you decide what to eat?

We spoke with 17 adults in a regional centre of Victoria. We chose a regional location because less research has been done with people living outside of metropolitan areas and because rates of obesity and other diet-related health issues are higher in such areas in Australia.

Participants included a mix of people, including some who said they were over their “most healthy weight” and some who had previously dieted to lose weight. But all participants were either:

• young women aged 18–24 with no children
• women aged 35–45 with primary school aged children
• men aged 35–50 living with a partner and with pre- or primary-school aged children.

We selected these groups to target ages and life-stages in which shifts in eating behaviours may occur. Previous research has found younger women tend to be particularly concerned about appearance rather than healthy eating, while women with children often shift their focus to providing for their family. Men tend to be less interested in what they eat.

We asked participants about how they decided what food to eat, when, and how much, and what prevented them from making healthier choices.

It’s not just about taste and healthiness

We found that, although such decisions were determined in part by taste preferences and health considerations, they were heavily influenced by a host of other factors, many of which are outside the person’s control. These included other household members’ food preferences, family activities, workplace and time constraints, convenience and price.

Healthy eating means consuming a balanced diet rich in nutrients, including a variety of fruits, vegetables, whole grains, lean proteins and healthy fats, while limiting processed foods, added sugars and excessive salt. Healthy eating also includes how we eat and how we think about food and eating, such as having a positive relationship with food.

One 35- to 45-year-old woman, for example, said that time constraints and family preferences made it difficult to prepare healthier food:

I love the chance when I can actually get a recipe and get all of the ingredients and make it properly, but that doesn’t happen very often. It’s usually what’s there and what’s quick. And what everyone will eat.

One of the 35- to 50-year-old men also noted the extent to which family activities and children’s food preferences dictated meal choices:

Well, we have our set days where, like Wednesday nights, we have to have mackie cheese and nuggets, because that’s what the boys want after their swimming lesson.

Research shows that children are often more receptive to new foods than their parents think. However, introducing new dishes takes additional time and planning.

An 18- to 24-year-old woman discussed the role of time constraints, her partner’s activities, and price in influencing what and when she eats:

My partner plays pool on a Monday and Wednesday night, so we always have tea a lot earlier then and cook the simple things that don’t take as long, so he can have dinner before he goes rather than buying pub meals which cost more money.

Despite popular perceptions, healthy diets are not more expensive than unhealthy diets. A study comparing current (unhealthy) diets with what the Australian Dietary Guidelines recommend people should eat found that the healthy diet was 12–15% cheaper than unhealthy diets for a family of two adults and two children.

However, learning and planning to prepare new types of meals takes effort and time.

Simply educating people about what they should eat won’t necessarily result in healthier eating. People want to eat healthier, or at least know they should eat healthier, but other things get in the way.

A key to improving people’s eating behaviours is to make it easy to eat more healthily.

Policy changes to make healthy eating easier could include subsidising healthier foods such as fresh produce, providing incentives for retailers to offer healthy options, and ensuring access to nutritious meals in schools and workplaces.

So how can you make healthier food choices easier?

Here are five tips for making healthy choices easier in your household:

1. If certain days of the week are particularly busy, with little time to prepare fresh food, plan to cook in bulk on days when you have more time. Store the extra food in the fridge or freezer for quick preparation.

2. If you’re often pressed for time during the day and just grab whatever food is handy, have healthy snacks readily available and accessible. This could mean a fruit bowl in the middle of the kitchen counter, or wholegrain crackers and unsalted nuts within easy reach.

3. Discuss food preferences with your family and come up with some healthy meals everyone likes. For younger children, try serving only a small amount of the new food, and serve new foods alongside foods they already like eating and are familiar with.

4. If you rely a lot on take-away meals or meal delivery services, try making a list ahead of time of restaurants and meals you like that are also healthier. You might consider choosing lean meat, chicken, or fish that has been grilled, baked or poached (rather than fried), and looking for meals with plenty of vegetables or salad.

5. Remember, fruit and vegetables taste better and are often cheaper when they are in season. Frozen or canned vegetables are a healthy and quick alternative.

Australia has a nationwide teacher shortage. But there is a particular shortage of Aboriginal teachers. This is very worrying because we know Aboriginal teachers are desperately needed to boost learning and school outcomes for Aboriginal students.

Not only do they bring vital cultural knowledge to schools, it also means Aboriginal students are represented by those who educate them. Aboriginal teachers can use Indigenous knowledge in the classroom and build effective student-teacher relationships which are vital for learning.

To boost the overall teaching workforce in late 2023, the federal government launched a campaign to “Be That Teacher”. But we need more specific measures, designed to resonate with Aboriginal students and communities.

In a new, ongoing project, we are talking to Aboriginal high school students and teachers to understand how we can encourage more Aboriginal people to become teachers in the Northern Territory.

What are the current figures?

As of 2023, 39.3% of school students in the NT were Aboriginal and Torres Strait Islander, this is the highest proportion of any state or territory. Nationally, Aboriginal students account for 6.5% of all school students.

As of 2020, there were 260 registered Aboriginal and Torres Strait Islander teachers in the NT. This includes the public, private and Catholic system and represents only 4.6% of the teaching workforce.

As of June 2024, there were just 163 Aboriginal teachers, senior teachers and principals in the public system, according to the NT Department of Education.

While there are existing initiatives to encourage Aboriginal people to become teachers, such as the Remote Aboriginal Teacher Education program, clearly more can be done to increase teacher numbers.

Our project

In an ongoing project, in collaboration with the NT Department of Education, we are talking to students and teachers to ask:

how can Aboriginal people encourage and inspire each other to become teachers?

So far, we have surveyed 23 Aboriginal students and ten Aboriginal teachers across government, independent and Catholic schools. Students are in the final years of schooling and at least 16-years-old.

Do you want to be a teacher?

When asked if students would like to be a teacher when they left school, most students we surveyed responded negatively.

As one student said, “school environments are mentally damaging”. They added the best way to encourage young people to teach would be to “put them in a school that actually accepts them”.

Some of the main reasons students gave for not being interested in teaching were having other career plans, not being interested in school and their teachers’ attitudes to the profession.

Some said their teachers “don’t look enthusiastic about their job” and “always complain about it”. While it was not specified if their teachers are Aboriginal or non-Aboriginal, we know statistically, the vast majority of teachers in the NT are non-Aboriginal.

More information

Students are also telling us they want more information about what it is like to be teacher and the practicalities of the profession. As one student said, they want to be shown “how to be a teacher”.

Another respondent told us:

Sit and talk to them and ask if they are interested in becoming a teacher by explaining the benefits of helping young people.

Role models can help

A strong theme to emerge so far is the importance of role models. Students said their teachers could help them consider becoming a teacher by the way they do their jobs. This was particularly so if they portrayed the profession as one focussed on student success and passion.

One student told us students could be attracted to the profession if they were told about how teachers helped “the next generation [to] follow in elders’ footsteps”.

Students also said they needed encouragement. As one respondent told us, they are worried about being treated badly by students.

Tell [students] that they can do it and do not need to be afraid.

Teachers’ own experiences matter

Aboriginal teachers also emphasised the importance of role models and personal experience. They told us their experience at school, whether as a student or later working in supporting roles, was a key reason behind deciding to teach. As one teacher said:

I loved school. I was really lucky enough that I had a school and teachers that were engaging and really lovely people.

But another was also inspired by negative experiences growing up:

I wanted to be a better teacher than the ones I’d had.

They stressed how passion was integral to their work and helping students to learn. They also talked of the importance of culture – something that could be emphasised with potential new recruits. As one teacher told us:

[I am] putting my own perspective on things. Embedding Indigenous content and a different pedagogical [teaching] approach.

Another teacher told us their work also had a simple purpose: “to combat racism”.

What now?

Our research is showing the need for more accessible information for Aboriginal students on how they get into a teaching career. According to students and teachers alike there is also a need for role models to encourage Aboriginal students to take up teaching.

We will keep surveying students and teachers this year and translate our findings into materials and information for universities and schools by the end of 2024.

This article talks primarily about Aboriginal people. Some of the data sources we accessed describe “Aboriginal and Torres Strait Islander,” statistics, which is why different terms have been used.

In March 2002, the Larsen B Ice Shelf collapsed catastrophically, breaking up an area about one-sixth the size of Tasmania.

In a paper published today in Scientific Reports, we used nearly 1,000 film photographs of Antarctica from the 1960s to reconstruct exactly what five glaciers were like decades before the Larsen B Ice Shelf collapse. This allowed us to precisely calculate their contribution to sea-level rise.

Although Antarctica is far away, and changing conditions there may seem distant, the changes can have a profound effect for us all. The removal of an ice shelf can cause glaciers to rapidly melt into the ocean and raise global sea levels.

After consecutive years of unusually warm temperatures, the Larsen B Ice Shelf collapsed over the course of a week. This induced dramatic change for the glaciers that used to flow into it. The glaciers have since been thoroughly monitored – but there were few observations of them before 2002.

However, an archive of more than 300,000 historical images contains an invaluable record of this area from 1968 and helped us measure the difference between then and now.

Observing glaciers

Ice shelves are thick floating bodies of ice attached to the coastline of Antarctica. The melting of an ice shelf does not directly cause sea-level rise.

However, ice shelves “hold back” the flow of glaciers. Once the shelves are removed, glaciers rapidly melt into the ocean. This transfers ice from the land to the ocean and causes sea-level rise.

To accurately predict how Antarctica’s glaciers will respond to future climate change, it is critical to understand how they have responded in the past. But some places in Antarctica are so remote, it is almost prohibitively difficult and expensive to get there and gather data.

Scientists often look to satellites to collect data because it is relatively cheap and easy. However, persistent cloud cover on the Antarctic Peninsula can interfere with satellite observations for most of the year.

This means that for many areas in Antarctica, observations are rare and often short-term.

Historical photographs are an invaluable record

Between 1946 and 2000, United States Navy cartographers flew over almost every corner of Antarctica recording 330,000 high-quality, large-format film photographs in an effort to map the continent.

Scans of the photographs have been archived by the Polar Geospatial Center, University of Minnesota and are available to freely download. These photographs are as high resolution as what many modern satellites can capture.

We created accurate and real-world scaled 3D models of five glaciers in the Larsen B area using a technique called photogrammetry. Traditional photogrammetry uses two overlapping photos from different angles to create a 3D surface – like how our two eyes can visualise objects in three dimensions.

Advances in computing now allow hundreds of overlapping photos to be combined with relative ease. Matching points in overlapping photos are detected automatically and their 3D position is calculated geometrically. An accurate glacier surface can then be made from a cloud of millions of matching points.

Identifiable features in the images with known coordinates, like nearby mountain peaks or uniquely shaped boulders, can then be assigned a GPS point to scale the model.

Then and now

After comparing five glaciers in 1968 and 2001 (the latter just months before the collapse), we found they were relatively unchanged.

After the collapse, the glaciers lost 35 billion tons of land-based ice. From one large glacier, 28 billion tons was lost: equivalent to around 0.1 mm of global sea-level rise.

This doesn’t sound like much, but is the result of one glacier from one event. Put another way, it is equal to every single person on Earth tipping out a one litre water bottle every day for ten years.

These images were essential to observing the glaciers in high resolution decades before they were affected by the ice shelf collapse.

A new record of Antarctica

As climate change accelerates, warming of the atmosphere and ocean threatens the remaining ice shelves on the Antarctic Peninsula. The historical image archive will become increasingly important to extend the record of change and establish just how significantly things are changing.

The same images could be used to investigate other ice shelves or glaciers, changes to coastlines, penguin colonies, the expansion of vegetation, or even direct human impacts.

The historical image archive is a priceless resource waiting to be tapped.

Since the release of ChatGPT in November 2022, the world has seen an incredible surge in investment, development and use of artificial intelligence (AI) applications. According to one estimate, the amount of computational power used for AI is doubling roughly every 100 days.

The social and economic impacts of this boom have provoked reactions around the world. European regulators recently pushed Meta to pause plans to train AI models on users’ Facebook and Instagram data. The Bank of International Settlements, which coordinates the world’s central banks, has warned AI adoption may change the way inflation works.

The environmental impacts have so far received less attention. A single query to an AI-powered chatbot can use up to ten times as much energy as an old-fashioned Google search.

Broadly speaking, a generative AI system may use 33 times more energy to complete a task than it would take with traditional software. This enormous demand for energy translates into surges in carbon emissions and water use, and may place further stress on electricity grids already strained by climate change.

Energy

Most AI applications run on servers in data centres. In 2023, before the AI boom really kicked off, the International Energy Agency estimated data centres already accounted for 1–1.5% of global electricity use and around 1% of the world’s energy-related CO₂ emissions.

For comparison, in 2022, the aviation sector accounted for 2% of global energy-related CO₂ emissions while the steel sector was responsible for 7–9%.

How is the rapid growth in AI use changing these figures? Recent environmental reporting by Microsoft, Meta and Google provides some insight.

Microsoft has significant investments in AI, with a large stake in ChatGPT-maker OpenAI as well as its own Copilot applications for Windows. Between 2020 and 2023, Microsoft’s disclosed annual emissions increased by around 40%, from the equivalent of 12.2 million tonnes of CO₂ to 17.1 million tonnes.

These figures include not only direct emissions but also indirect emissions, such as those caused by generating the electricity used to run data centres and those that result from the use of the company’s products. (These three categories of emissions are referred to as Scope 1, 2 and 3 emissions, respectively.)

Meta too is sinking huge resources into AI. In 2023, the company disclosed is Scope 3 emissions had increased by over 65% in just two years, from the equivalent of 5 million tonnes of CO₂ in 2020 to 8.4 million tonnes in 2022.

Google’s emissions were almost 50% higher in 2023 than in 2019. The tech giant’s 2024 environmental report notes that planned emissions reductions will be difficult “due to increasing energy demands from the greater intensity of AI compute”.

Water

Data centres generate a lot of heat, and consume large amounts of water to cool their servers. According to a 2021 study, data centres in the United States use about 7,100 litres of water for each megawatt-hour of energy they consume.

Google’s US data centres alone consumed an estimated 12.7 billion litres of fresh water in 2021.

In regions where climate change is increasing water stress, the water use of data centres is becoming a particular concern. The recent drought in California, where many tech companies are based, has led companies including Google, Amazon and Meta to start “water positive” initiatives.

These big tech firms have announced commitments to replenish more water than they consume by 2030. Their plans include projects such as designing ecologically resilient watershed landscapes and improving community water conservation to improve water security.

Climate risk

Where data centres are located in or near cities, they may also end up competing with people for resources in times of scarcity. Extreme heat events are one example.

Globally, the total number of days above 50°C has increased in each decade since 1980. July 2023 was the hottest month ever recorded.

Extreme heat translates to health impacts on local populations. A Lancet 2022 study found that even a 1°C increase in temperature is positively associated with increased mortality and morbidity.

On days of extreme heat, air conditioning can save lives. Data centres also like to keep cool, so their power use will spike with the temperature, raising the risk of blackouts and instability in electricity grids.

What’s next?

So what now? As we have seen, tech companies are increasingly aware of the issue. How is that translating into action?

When we surveyed Australian sustainability professionals in July 2023, we found only 6% believed data centre operators provided detailed sustainability data.

Earlier this year we surveyed IT managers in Australia and New Zealand to ask what they thought about how AI applications are driving increased energy use. We found 72% are already adopting or piloting AI technologies.

More than two-thirds (68%) said they were concerned about increased energy consumption for AI needs. However, there is also significant uncertainty about the size of the increase.

Many IT managers also lack the necessary skills to adequately address these sustainability impacts, regardless of corporate sustainability commitments. Education and training for IT managers to understand and address the sustainability impacts of AI is urgently required.

Senator Fatima Payman’s defection over Labor Party policy on statehood for the Palestinians has generated wider discussion about the written and unwritten rules of Australian politics. One of those involves the vexed question of the role of religious faith.

Scott Morrison’s prime ministership inevitably raised it. Morrison did not hide his evangelical Christianity. His strange memoir revived the issue because it showed Morrison’s faith was not incidental to his politics. By his own account at least, faith was its organising principle.

So far as I’m aware, Morrison’s Christianity was not understood as a threat to social cohesion – weird, certainly, but not dangerous in that way. Those who talked up its dangers were often treated as engaging in hyperbole, or even hypocrisy – since Kevin Rudd’s Christianity did not receive the same level of scrutiny or criticism.

The context for Albanese’s commentary was Payman’s defection, and reports that she had been in contact with an organisation called The Muslim Vote, which intends organising candidates in Labor-held seats with large numbers of voters of this faith:

I don’t think and don’t want Australia to go down the road of faith-based political parties because all that will do is undermine social cohesion. It seems to me, as well, beyond obvious that it’s not in the interest of small and minority groups to isolate themselves – which is what a faith-based party system would do.

Even a cursory glance at the historical record indicates a long list of Australian minor parties that were explicitly Christian. Albanese probably disliked each and every one of them, but they have not usually attracted his adverse notice. The parties used by Fred Nile and his wife Elaine – Call to Australia and the Christian Democratic Party – to get themselves elected to the New South Wales Legislative Council are among the best known, but there were many others.

There was a Protestant Independent Labor Party in the 1920s, active mainly in New South Wales, formed by Walter Skelton. He was able to take advantage of a short-lived experiment in multi-member constituencies and proportional representation to get himself a Legislative Assembly seat. Skelton was elected at a time when religious sectarianism was often vicious, and frequently spilt over into mainstream political contention.

Politicians of the centre right – then concentrated in the Nationalist Party – harvested the issue for votes. The most notorious of them was Thomas Ley, a minister in the New South Wales state government and later a federal parliamentarian. He moved on from a career in parliamentary politics and Catholic-baiting to one in crime. Ley was widely suspected of killing a political opponent in 1925 and later, in England, he was convicted of a murder.

Religious sectarianism – essentially conflict between Catholics and Protestants – was once a drain on Australia’s social cohesion. As Australia’s party system emerged, the Labor Party was disproportionately Catholic. Meanwhile, its non-Labor rival – operating under various names before settling on “Liberal” in 1944 – was overwhelmingly Protestant in composition if not invariably in electoral support.

“Be careful, boys. Here comes the Papist”, Robert Menzies would joke in the presence of John Cramer, a rare Catholic bird in the Liberal nest. It is only in recent decades that some Catholics have been able to find a more comfortable home in the Liberal Party.

Two of Labor’s three great splits of the 20th century were deeply influenced by religious sectarianism: in 1916, over conscription for overseas service, and in 1955, over such matters as policy towards communism and the Catholic Church’s involvement in labour movement affairs. The breakaway party that emerged from the latter split, the Democratic Labor Party (DLP), was ostensibly secular but Catholic in all but name.

Albanese undoubtedly has a genuine objection to faith-based political parties. He is a mainstream politician with secular leanings and a strong commitment to existing social and political institutions. It is nonetheless hard to escape the impression that what is most alarming for critics is not merely that the party might be faith-based as such, but that it would register a Muslim political identity. That would challenge authorised ways of imagining political identity in Australia.

Australia’s multiculturalism worries over the place of Muslims in Australian society. The country calls itself secular, but retains a Christian identity in culturally ambiguous but nonetheless tangible ways.

Muslims are commended when they conform to the role of model minority in such a society. Explicit support for “Australian values” is regularly demanded of them in a way no Christian migrant group experiences. A key measure of community integration is understood as absorption into the existing political institutions of the country. For Albanese, that includes his beloved Labor Party.

Talk of a Muslim party or political movement is seen to challenge social cohesion. It does not conform with a key demand made of people of Muslim faith: that they accept the existing rules of political engagement. Here is a conservative face of multiculturalism, as discussed by scholars such as Ghassan Hage. The rules migrant communities are expected to follow are overwhelmingly the handiwork of the host society, not of migrants.

The most serious challenges for Australia’s political system and social cohesion are not the prospect of a Muslim party or political movement. It may well go the same way as the plethora of minor Christian parties of the past.

Rather, it is how we can make our political system work in a way that responds effectively to the cultural diversity of our society while preserving what is most authentically democratic about it. We certainly can’t do that if we insist that only some of us get a say in making the rules.

Late last week, the remains of a missing 12-year-old girl were found after she was taken by a saltwater crocodile in the Northern Territory.

The incident occurred in a waterway known as Mango Creek near the community of Nganmarriyanga/Palumpa in the remote and sparsely populated West Daly region, about 350 kilometres southwest of Darwin.

Understandably, the tragedy elicited a strong reaction from the public – including debate about crocodile numbers in the wild.

I am based in the Northern Territory and have worked extensively in the field of human-crocodile conflict management, including establishing CrocAttack, a global open-source database of crocodilian attacks. Amid the emotion surrounding this latest incident, it’s important to remember fatal crocodile attacks are extraordinarily rare in Australia – and there is no evidence to suggest their numbers are too high.

Croc numbers don’t equate to attacks

Saltwater crocodiles in NT number about 100,000 (excluding those just hatched). Research shows about five crocodiles, on average, for every kilometre of waterway in the territory.

Fatal crocodile attacks in the NT peaked in 2014 when four people died. Prior to the latest incident, the last fatal attack in the NT occurred in 2018 when an Indigenous ranger was killed while fishing with her family.

The fatality rate is far lower than elsewhere in the saltwater crocodile’s range. In Indonesia, for example, at least 85 people were killed last year alone. What’s more, crocodile incidents in Indonesian Papua are believed to go largely unreported, so the number of actual deaths is likely much higher.

Despite this, there appear to be vastly fewer crocodiles in Indonesia. Most surveys reveal densities of significantly less than one individual per kilometre in waterways.

Why crocodile attacks in the NT are rare

There are several theories on why saltwater crocodile attacks are comparatively rare in Australia.

First, Australians generally have access to fresh water in their homes. Unlike people in, say, Indonesia, they do not need to travel to waterways to bathe, carry out domestic chores and collect drinking water. That means they are less likely to encounter crocodiles.

Second, Australians have access to fishing equipment which does not require them to submerge themselves in waterways to fish, and safer fishing vessels which, unlike in Indonesia, are not prone to capsizing.

The Northern Territory is also more sparsely populated and developed than other areas where saltwater crocodiles live. That means less habitat destruction, more natural prey for crocodiles, and fewer people in crocodile habitat.

Importantly, the Northern Territory also has an extensive crocodile safety education program in the form of the CrocWise campaign, as well as a robust management plan.

Crocs don’t need culling

The NT crocodile management plan was recently amended to increase the territory’s crocodile removal quota from 300 to 1,200 a year, stopping short of a widespread cull.

However, each time a croc attack is recorded in Australia, it provokes debate about whether tougher management of croc numbers is required.

Following the latest crocodile attack, NT Chief Minister Eva Lawler told the ABC:

We can’t have the crocodile population outnumber the human population in the Northern Territory […] We do need to keep our crocodile numbers under control.

Claims that crocodile populations need “controlling” make little sense. Research shows apex predators such as crocodiles do not overpopulate. Crocodile numbers in the Northern Territory have never been, and will never be, out of control.

This is particularly true for the saltwater crocodile, for which less than 1% of hatchlings survive to adulthood. It is also a fiercely territorial species, and conflict between males often results in death.

A 2015 Australian study found removing all crocodiles from a location was not a practical option, given the species’ mobility and dispersal across a range of habitats. It said culling programs would not ensure the absence of crocodiles in a targeted area and swimming activities would remain unsafe to the public.

Other Australian research has found crocodile numbers would have to fall by 90% to prevent one annual attack.

Preventing crocodile attacks in the Northern Territory requires more community education, more signs warning of the crocodile danger, and tougher fines for people wilfully engaging in unsafe behaviour.

New tools are also being developed. This includes detecting crocodiles with multi-beam sonar in areas where the attack risk is high, and attaching magnets to crocodiles while moving them to disrupt their natural homing instinct. These methods require further studies.

Ultimately, through public education and management, it is possible for humans to live alongside crocodiles with minimal conflict.

Our ageing population brings a growing crisis: people over 65 are at greater risk of dual sensory impairment (also known as “deafblindness” or combined vision and hearing loss).

Some 66% of people over 60 have hearing loss and 33% of older Australians have low vision. Estimates suggest more than a quarter of Australians over 80 are living with dual sensory impairment.

Combined vision and hearing loss describes any degree of sight and hearing loss, so neither sense can compensate for the other. Dual sensory impairment can occur at any point in life but is increasingly common as people get older.

The experience can make older people feel isolated and unable to participate in important conversations, including about their health.

Causes and conditions

Conditions related to hearing and vision impairment often increase as we age – but many of these changes are subtle.

Hearing loss can start as early as our 50s and often accompany other age-related visual changes, such as age-related macular degeneration.

Other age-related conditions are frequently prioritised by patients, doctors or carers, such as diabetes or heart disease. Vision and hearing changes can be easy to overlook or accept as a normal aspect of ageing. As an older person we interviewed for our research told us

I don’t see too good or hear too well. It’s just part of old age.

An invisible disability

Dual sensory impairment has a significant and negative impact in all aspects of a person’s life. It reduces access to information, mobility and orientation, impacts social activities and communication, making it difficult for older adults to manage.

It is underdiagnosed, underrecognised and sometimes misattributed (for example, to cognitive impairment or decline). However, there is also growing evidence of links between dementia and dual sensory loss. If left untreated or without appropriate support, dual sensory impairment diminishes the capacity of older people to live independently, feel happy and be safe.

A dearth of specific resources to educate and support older Australians with their dual sensory impairment means when older people do raise the issue, their GP or health professional may not understand its significance or where to refer them. One older person told us:

There’s another thing too about the GP, the sort of mentality ‘well what do you expect? You’re 95.’ Hearing and vision loss in old age is not seen as a disability, it’s seen as something else.

Isolated yet more dependent on others

Global trends show a worrying conundrum. Older people with dual sensory impairment become more socially isolated, which impacts their mental health and wellbeing. At the same time they can become increasingly dependent on other people to help them navigate and manage day-to-day activities with limited sight and hearing.

One aspect of this is how effectively they can comprehend and communicate in a health-care setting. Recent research shows doctors and nurses in hospitals aren’t making themselves understood to most of their patients with dual sensory impairment. Good communication in the health context is about more than just “knowing what is going on”, researchers note. It facilitates:

• shorter hospital stays
• fewer re-admissions
• reduced emergency room visits
• better treatment adherence and medical follow up
• less unnecessary diagnostic testing
• improved health-care outcomes.

Too many Australians are waiting for a home care package. Here’s how to fix the delays

‘Too hard’

Globally, there is a better understanding of how important it is to maintain active social lives as people age. But this is difficult for older adults with dual sensory loss. One person told us

I don’t particularly want to mix with people. Too hard, because they can’t understand. I can no longer now walk into that room, see nothing, find my seat and not recognise [or hear] people.

Again, these experiences increase reliance on family. But caring in this context is tough and largely hidden. Family members describe being the “eyes and ears” for their loved one. It’s a 24/7 role which can bring frustration, social isolation and depression for carers too. One spouse told us:

He doesn’t talk anymore much, because he doesn’t know whether [people are] talking to him, unless they use his name, he’s unaware they’re speaking to him, so he might ignore people and so on. And in the end, I noticed people weren’t even bothering him to talk, so now I refuse to go. Because I don’t think it’s fair.

So, what can we do?

Dual sensory impairment is a growing problem with potentially devastating impacts.

It should be considered a unique and distinct disability in all relevant protections and policies. This includes the right to dedicated diagnosis and support, accessibility provisions and specialised skill development for health and social professionals and carers.

We need to develop resources to help people with dual sensory impairment and their families and carers understand the condition, what it means and how everyone can be supported. This could include communication adaptation, such as social haptics (communicating using touch) and specialised support for older adults to navigate health care.

Increasing awareness and understanding of dual sensory impairment will also help those impacted with everyday engagement with the world around them – rather than the isolation many feel now.

Evidence is mounting that the new generative AI internet search tools provided by OpenAI, Google and Microsoft can increase the risk of returning false, misleading or partially correct information.

Despite the implications of this for the news industry and an informed democracy, the New Zealand government has decided to leave AI considerations out of its plans to revive the previous government’s Fair Digital News Bargaining Bill.

The proposed law will require Google and Meta (which runs Facebook and Instagram) to pay news companies for their content. While plenty of local news organisations receive money from Google, they don’t receive payments from Meta.

Media and Communications Minister Paul Goldsmith says the proposed bill will have some amendments, but these will not be related to the increasing role of generative AI in news searches. The “broad issue of AI” would be considered later, he says.

However, the bill will give the minister the power to decide which companies will be included under a new law, potentially opening the door to bring the likes of Microsoft and OpenAI to the negotiating table.

How do news companies respond?

AI-powered chatbots such as Google’s Gemini, Microsoft’s Copilot and OpenAI’s ChatGPT respond to user prompts, giving answers based on information “scraped” from the internet, including news media sites. They also use news content – or any content they can find – to “train” their AI models.

As AI companies are struggling to find enough data to do this training, they are making deals with news companies to use their content, including archives, to feed into their models.

Therefore, it is not surprising many big news companies – including News Corp, The Financial Times (owned by Nikkei) and Germany’s Axel Springer – have signed commercial deals for their content with AI companies.

On the other hand, companies such as The New York Times and Alden Global Capital (the second largest newspaper owner in the US) have taken a different approach. They are suing Microsoft and OpenAI for “illegally using news articles to power their AI chatbots”.

Alden says OpenAI and Microsoft use “millions of its copyrighted articles without permission and it uses these to train and feed their generative AI products”.

In 2023, leading New Zealand news publisher Stuff stopped ChatGPT from using its stories to feed its software models. Since then, my new research shows Stuff’s news content has also dropped in visibility in Google’s and Microsoft’s searches.

News diversity is shrinking

I analysed what Microsoft’s and Google’s search engines and their respective chatbots, Copilot and Gemini, offer as news.

In general, search engines return results based on a user’s inquiry, linking to information. Chatbots use large language models to create answers by scraping data from sources, often without any links to information.

The study gathered three months of data in 2023 and again in 2024. Search engines were prompted to offer the “main news in New Zealand today”, and chatbots were asked to provide links and sources to news stories.

The results showed news diversity shrank in Google and Microsoft search. While both search engines offered news from legacy news media outlets, the category “other sources” grew dramatically between 2023 and 2024.

What these AI-powered search engines offer as “news” sources is worrying. They increasingly link to random, non-news sources such as industry forums and press releases.

Furthermore, the Google Gemini and Microsoft Copilot chatbots offered old stories as the main news of the day, did not give links to the specific news stories, and gave no sources in the answers they provided.

Having been asked about the main news in New Zealand today, the search engines were then asked: can you give any sources for the stories? This from Google Gemini was representative of the responses:

I am a large language model, and I am able to communicate and generate human-like text in response to a wide range of prompts and questions. Is there anything else I can do to help you with this request?

As more data is fed into AI-powered searches and chatbots, they may become more accurate. Until then, however, users should be careful about the reliability or independence of information sourced this way.

Democracy, news and AI

Dealing with AI companies has left news organisations in a difficult situation. If they don’t make deals, they may lose potential extra revenue. If they do, there is no guarantee how their content will appear in generative AI search or chatbots.

In May this year, for example, Google confirmed its search engine will offer more AI answers than website links. This means it will provide detailed AI responses to user prompts, and snapshot summaries without linking to any sources of information.

If the links disappear from the AI-generated search responses, it potentially means Google and other providers don’t need to pay news companies for the snippets and links they have been using in their services. This may have implications for the revived Fair Digital News Bargaining Bill.

On the other hand, AI providers are already paying some news companies for their current and archived content to train their chatbots, which could lead to better search results.

How this all plays out will have consequences for democracy as much as for media revenues, which my ongoing research aims to investigate.

The figure of Dracula has always lived somewhere between the written word, screen projections and our fantasy lives. His story is tailor-made for one of Kip Williams’ hybrid adaptations.

Williams’ technique is, by now, familiar to Sydney audiences. Again with Dracula, the third part of this loose trilogy, he makes spectacular use of live action, live filming and recorded video, all interwoven into exciting spectacles that drive the story forward.

Dracula on screen

Bram Stoker’s novel was first published in 1897. It only took 24 years for the count to make his way onto screen. This first film version appeared more than a hundred years ago: a lost 1921 Austrian silent movie, Drakula halála.

More familiar is F.W. Murnau’s loose adaptation, Nosferatu (1922), with its startling central performance from Max Schreck.

From these early appearances, cinema did not look back, bringing us multiple Hammer Horror appearances, the camp romanticism of Coppola’s more faithful adaptation in 1992, and onwards to this year’s much-anticipated revisiting of the Murnau film from director, Robert Eggers.

The Sydney Theatre Company production makes some cheeky references to these screen versions while developing a compelling visual language of its own. It all centres on Zahra Newman’s utterly brilliant performance of all 23 characters.

Her virtuosic shifts between the count’s victims, his multiple hunters, and the glamorous vampire himself ensure the audience is drawn into a world of desire, fantasy and horror from start to finish.

A queer rewriting

Dracula’s use of journals, newspaper reports, and letters really lends itself to this kind of stage treatment, but the difficulty of adapting a long-ish novel into a short live production does strain the audience’s capacity to keep up at times.

If you aren’t familiar with the story (and perhaps it’s OK to assume that people are familiar with it?) then some sequences might escape you.

Williams’ habit of faithfully reproducing the prose really worked in Jekyll and Hyde, mainly because Stevenson is a beautiful writer.

But Stoker’s strengths as a writer do not lie in his prose style and, in the word-laden first half of this production, there is a sense of trying to cram in too much.

That said, Williams has made some judicious cuts throughout, all of which lead to a stunning and subtly celebratory queer rewriting of the novel’s final passages.

About half way through the production, the monologues give way to much more intense visual spectacle. Some of the production’s welcome humour falls away, to be replaced by some really sexy uses of the stage, much of it leaving the audience gasping with gleeful surprise.

An emerging modern world

In common with the other two pieces of writing from the 1890s Williams has brought to the stage as a trilogy, Dorian Gray and Jekyll and Hyde, Stoker’s Dracula reflects on an emerging modern world at the turn of the century and considers whether older ideas of crime, sin, virtue and heroism will still be of use.

The way the story of the novel is told is firmly wedded to the modern world: diaries are recorded on phonograph and transcribed by typewriters that produce automatic copies; people communicate via telegram as well as in letters; journeys are taken by train and steam ship as well by horse and sail.

It is a world in which it seems like an old world is being replaced by modernity.

But, with the vampire’s refusal to die, old ideas reassert themselves: superstitions and old moralities cannot be left behind quite so easily. As Van Helsing says:

It is the fault of our science that it wants to explain all; and if it explain not, then it says there is nothing to explain.

Where Stoker’s novel might lean, albeit ambiguously, towards endorsing a reassertion of traditional morality in an modern uncertain world, subsequent adaptations have never been so sure.

This story has not persisted into our cinemas and within our imaginations because we side with Van Helsing and his brotherhood of Christian warriors but because, like the poor doomed Lucy Westenra, we are all half in lust with the vampire.

In this production, Williams extends the capacities of his hybrid staging, making it all much more private, personal and intimate.

Between the live action and the screened action, we see mouths, lips and eyes being continually overlaid.

Distinctions are blurred not only between the living and the dead but between the monster and his victims, and between the desirer and the desired. The count is dead; long live the count.

Dracula is at the Sydney Theatre Company until August 4.

Olympic Games are big affairs that require massive infrastructure projects to build the various stadiums and venues.

Many of the sports have specific requirements – fake whitewater and rocks for kayaking, huge slopes for ski jumps, or sand for beach volleyball. On top of that, these venues need to be able to support large crowds and the technology needed to manage the events.

As former Victorian premier Dan Andrews discovered in 2023, hosting big sporting events costs big money.

The Tokyo Olympics are estimated to have cost A$23 billion dollars, a lot of which was spent building infrastructure.

A 2022 report from the International Olympic Committee revealed that 85% of the stadiums, venues and structures used in the Olympics are currently still in use.

But how are they used, were they new structures and what happened to the 15% of venues that have fallen into disuse?

Stadiums

The all-marble Panathenaic Stadium hosted the first modern Olympics in Athens, Greece in 1896. It was used again during the 2004 Olympics (archery and the marathon finish) and is now a popular tourist attraction that has hosted events such as concerts and fashion shows in recent years.

Francis Olympic Field in St Louis in the United States was used as the main venue for the 1904 Summer Olympics. It is the oldest Olympic stadium still in regular use for official sporting events.

It has been renovated several times and is currently used by Washington University’s track and field, cross country, football, and soccer teams.

Many Olympic stadiums continue to be used for local, national and international sports such as athletics and soccer, as well as large concerts and performances.

For example, the 1960 Summer Olympic Stadium in Rome, Italy is the home ground of the national rugby union team and soccer clubs Roma and Lazio. It has also hosted matches in the 1990 FIFA Soccer World Cup, UEFA Soccer Champions League, World Athletics Championships and more.

Fisht Stadium in Sochi, Russia hosted the 2014 Winter Olympics and Paralympics. It also hosted games in the 2018 Soccer World Cup (including Australia vs Peru) and is now the home stadium for soccer team PFC Sochi.

Cities that have hosted multiple Olympics have refurbished and reused venues.

For example Tokyo reused 1964 venues such as the Tokyo Metropolitan Gymnasium and Nippon Budokan Hall in 2021; the Los Angeles Memorial Coliseum and Rose Bowl were both Summer Olympic sites in 1932 and 1984 and will be used again in 2028.

Venues

Olympic venues continue to be used for sporting and non-sporting activities.

Many existing venues such as skiing slopes and summer venues such as Banyoles Lake (rowing – 1992 Barcelona Summer Olympics) and Wimbledon (tennis – 1908 and 2012 London Summer Olympics) hosted their sport before the Olympics and have continued to host it after the Olympics.

Other venues have been reused in a variety of ways.

For example, the stadium and skating and ice hockey venues used in the 1928 and 1948 Winter Olympics in St Moritz, Italy are now part of a private residence.

The 1980 Winter Olympic village in Lake Placid, US, is now a federal prison.

The Water Cube (swimming, diving, water polo – 2008 Beijing Summer Olympics) is now a popular water park.

Unused Venues

Some Olympic venues such as the Mt Eniwa downhill events site (alpine skiing – 1972 Sapporo Winter Olympics) and Copacabana beach volleyball arena (beach volleyball – 2016 Rio Summer Olympics) were temporary venues that were dismantled after the games as planned.

Many other older venues have been renovated and redeveloped.

Other venues have unfortunately fallen into disrepair for various reasons.

The Trebevic Olympic Bobsleigh and Luge Track (bobsleigh, luge – 1984 Sarajevo Winter Olympics) was damaged during the Bosnian War (1992-1995) and has not been repaired. It is now overgrown and covered with graffiti.

Alonzo Herndon Stadium (hockey – 1996 Atlanta Summer Olympics) is in a similar graffiti-covered state of disrepair.

Most of the Helliniko Olympic Complex (softball, canoe/kayak, hockey, baseball, basketball – 2004 Athens Summer Olympics) is closed or has been demolished due to poor planning and political, economic and administrative upheaval.

Australia

So how have Australia’s Olympic venues fared? In short, pretty well.

Most Melbourne 1956 Summer Olympic venues such as the Melbourne Cricket Ground (athletics, soccer, hockey, opening and closing ceremonies) and Exhibition Building (basketball, weightlifting, wrestling, modern pentathlon) are still used regularly.

Only the Melbourne Olympic Park Velodrome (cycling, currently a medical centre) and the Merritt Rifle Range (shooting, currently a housing estate) are not in use.

Venues built specifically for the Sydney 2000 Summer Olympics such as the Sydney International Aquatic Centre (swimming, diving, water polo) and Penrith Whitewater Stadium (canoeing, kayaking) continue to be some of the premier locations for their sports in Australia. The Olympic Village is now part of the suburb on Newington.

Some temporary venues such as the Bondi beach volleyball arena were dismantled after the games as planned. The Sydney Entertainment Centre (volleyball) is the only non-temporary venue no longer in use. It was demolished in 2016 as part of the redevelopment of Darling Harbour.

As we head towards the Brisbane Olympics in 2032, careful planning will be needed to ensure that planned infrastructure is cost effective and can be used by local residents, and others, for many years after the games have finished.

Policies designed to ensure Indigenous Australians have equitable access to medicines aren’t being accessed uniformly across the nation, our research shows.

We mapped where Indigenous Australians are using a program to access free or discounted medicines under the Pharmaceutical Benefits Scheme (PBS). We found access was patchy and depended on where you live.

This is particularly concerning as many Indigenous Australians in areas with high rates of chronic conditions are not using the program.

Here’s what could explain our findings and what needs to happen next.

What are ‘Closing the Gap’ scripts?

In 2010, the Australian government introduced the Closing the Gap PBS Co-payment Program (colloquially known as CTG scripts).

This program continues today and means Indigenous Australians:

• who would otherwise pay A$31.60 for a script, pay the concessional rate instead ($7.70)

• who would otherwise pay the concessional rate ($7.70) get their scripts for free.

The program was initially aimed at people with chronic disease. However, the program was changed in 2021 to increase access.

Now, Indigenous Australians can qualify regardless of age, chronic disease status, and provider location. Changes now mean all PBS prescribers and Aboriginal and Torres Strait Islander Health Practitioners can register patients. Registration is now one-off and lasts for a patient’s lifetime.

Initial research shows this program went some way to reduce inequities in access to health care. After it was introduced, Indigenous Australians used more prescription medicines and chronic disease services, and made more GP visits.

Other studies also suggest areas with higher uptake of the program had fewer hospitalisations for chronic conditions.

But uptake is patchy

Despite these benefits, our research shows uptake varied dramatically depending on where Indigenous Australians live.

We used census-linked data to estimate regional differences in the proportion of Indigenous patients who had ever received a CTG script between 2011 and 2020.

In parts of northern Australia less than 30% of the Indigenous population had ever received a CTG script. In Tasmania this was around 30-40%. This was ten years after the policy was introduced.

Uptake in other states, such as Victoria and New South Wales, varied considerably, ranging from 15% to 87%.

Why the regional differences?

There appear to be multiple and potentially interacting factors influencing uptake of the scheme.

1. Higher rates of chronic conditions in some areas

In some rural and remote areas – particularly in NSW, South Australia, and Victoria – higher uptake could be explained by higher rates of chronic conditions among Indigenous populations. People with chronic conditions are more likely to need ongoing scripts.

However, we don’t see this pattern in remote parts of Western Australia, the Northern Territory, Australian Capital Territory, Queensland and Tasmania, where we also see high rates of chronic conditions.

2. People may already be accessing other medicine subsidy programs

Broadly, Indigenous populations in remote areas are less likely to access CTG scripts. That’s because they can receive free prescription medicines through the Remote Area Aboriginal Health Services Program. So, for many Indigenous Australians in these regions there may be little perceived benefit to registering for CTG scripts.

However, this is not the case for Tasmania and Victoria where there is little-to-no access to this alternative program.

The rates of uptake of CTG scripts in Tasmania and the ACT were among the lowest in the country. However, the Indigenous populations in these regions have some of the highest rates of chronic conditions in the country. So other factors must be at play.

3. Red tape, not all health services on board

We also need to look at what’s happening in primary health care. Not all Indigenous patients are accurately identified. This could be because patients fear poorer care and don’t tell health services or because no-one asks. Smaller practices with less administrative support and those in more remote areas were also less likely to participate in the program.

Until 2021, when access to the program widened, fewer providers were eligible to register Indigenous patients to receive CTG scripts. This may have also affected access.

So this red tape and overall program complexity appears to have hindered Indigenous people from accessing the program.

How could we improve access?

1. Support Indigenous patients to feel safe

Many researchers and community leaders have written about the need to provide culturally safe health care, necessary to deliver safe, accessible and responsive health care free of racism.

Providing culturally safe care can make Indigenous people more likely to identify. This helps tailor care, so patients can access relevant and appropriate health services, such as CTG scripts, to improve health.

2. Engage communities

The regional variation of CTG uptake suggests community-level solutions are needed. Policymakers could consider additional targeting of resources based on location and community-specific factors. This might mean administrative or program support to deliver these initiatives, including via Aboriginal Health Services and better use of the Indigenous health workforce. We know these community programs have improved medicines access and continuity of care.

3. We need a data strategy

There is minimal analyses on CTG uptake and impacts since 2020. But this isn’t the only data gap, nor are all data about Indigenous Australians’ use of medicines linked.

For instance, the Australian Institute of Health and Welfare no longer reports data on Indigenous people’s use of PBS medicines; there is still no national system to capture remote medicines use; and minimal Indigenous data is reported for relevant community pharmacy programs, to name a few.

As outlined in the National Agreement on Closing the Gap, Indigenous Australians are the key stakeholders of the data discussed here. This means Indigenous Australians must “own” the data, and govern how it’s collected and used. Any program or policies involving that data must also be co-designed with Indigenous Australians.

Such principles are fundamental to ensure further evaluation and ongoing roll-out of programs, such as CTG scripts, are equitable and effective for Indigenous Australians.

Keeping the lights on in Australia is a complex task. Enough capacity must be ensured everywhere in the country, at every moment. Surplus in one location won’t solve shortages in another, unless we have the transmission infrastructure to transmit electricity between them.

The transmission network largely consists of high-voltage lines and towers, as well as transformers which transfer electrical energy from one circuit to another.

Australia’s transmission network is one of the oldest and longest in the world. As coal stations close and more renewable energy is built, the task of upgrading the system becomes even more pressing. So formidable is the challenge, it’s one of the biggest roadblocks Australia faces in reaching its crucial goal of net-zero emissions by 2050.

The Coalition’s plan for seven nuclear energy plants in Australia further complicates the task. A clear policy direction for Australia’s electricity system is urgently needed.

Lots of work to do

In technical terms, transmission congestion occurs when an element on the network, such as a high-voltage power line or transformer, reaches capacity and cannot carry more electricity.

Think of it as like traffic in a city. During rush hour, bottlenecks occur when there are more vehicles than the roads can handle. During times of peak electricity demand, electricity lines and transformers can also reach their limits. Exceeding the limits of the network can damage equipment and lead to power outages.

Between now and 2050, Australia’s electricity consumption will surge. We’ll need to draw power from increasingly diverse and far-flung sources. Coal power plants, typically located near large population centres, will close. Energy generation from solar and wind farms, usually located in regional and remote areas, will increase.

Importantly, we must make the distinction between electricity capacity and whether that electricity is “dispatchable”, or can be released on demand. That’s one reason why we need new transmission lines – to move electricity around the system as needed. The sooner we can build this capability, the quicker and cheaper our energy transition will be.

So far this decade, 490 kilometres of new transmission lines have reportedly been added to the National Electricity Market, which serves the east coast and South Australia. A further 2,090 km of transmission lines are progressing from the planning phase to the construction phase.

There’s still a lot of work to do: around 10,000 km of new transmission lines is needed by 2050. Western Australia’s main electricity network also needs more than 4,000 km of new high-capacity transmission lines.

A looming problem

The network’s ability to carry electricity is influenced by several factors. They include weather conditions, patterns of electricity generation and demand, the capacity of individual elements such as transmission lines and transformers, and their reliability.

Congested transmission can cause fluctuations in power prices. If cheaper electricity cannot be transported to where it’s needed, more expensive generators are dispatched to meet demand. This increases the price of electricity for both energy retailers and consumers. It can also lead to higher prices in some areas than others and poses financial risks for energy providers.

Transmission congestion in Australia is a looming problem. For example, South Australian transmission company ElectraNet forecasts rising congestion on that state’s network due to planned expansions of electricity generators, peaking in the late 2020s and 2030s.

What’s more, planning studies have identified ageing assets in Queensland’s transmission network, requiring new routes to manage constraints and ensure reliable supply.

Where does nuclear fit in?

All this has implications for the Coalition’s nuclear plan, if it comes to fruition.

The CSIRO and others say a nuclear power plant of any size would not be operational in Australia until after 2040.

If transmission lines are congested at that future point, nuclear power plants may not be able to send all their electricity to the grid.

Nuclear plants are expensive to build and run. But they typically generate electricity continuously, helping to offset these costs. If the plants can’t feed into the grid, or can’t sell their electricity at competitive prices, they may lose revenue and struggle to cover their costs, affecting their long-term viability.

The continuous high output of nuclear plants also helps them run efficiently. Frequently adjusting energy output leads to more wear, lower efficiency and reduced energy production over time.

Constraining nuclear output can have broader repercussions, too. In France, for instance, nuclear output is at a 30-year low, forcing the country to import electricity and prepare for potential blackouts. The reactors are offline for maintenance, not due to transmission issues. But the example highlights the consequences when nuclear energy is taken out of the mix for any reason.

Clarity is needed

Finally, the increasing share of renewable energy in our electricity grid means there’s no guarantee transmission capacity will be available for nuclear energy.

As South Australia’s energy minister Tom Koutsantonis noted on X, this poses challenges for the Coalition’s plan to build a nuclear plant at the site of an old coal station at Port Augusta and use existing transmission infrastructure:

The myth that a nuclear reactor could just plug into the old Pt Augusta coal power station transmission lines is not true. The transmission lines are already nearly full from new renewables. In truth, a nuclear reactor at Pt Augusta would need new transmission lines, the exact thing the LNP are complaining about.

So what’s the upshot of all this? Transmission infrastructure is a thorny policy problem, and divergent views among policymakers about energy policy only add to the challenges.

A clear direction on the future of Australia’s electricity grid, including transmission infrastructure, is essential. Without it, the energy transition will be slower and more expensive.

Next month, thousands of students and their families will find out whether they have been offered a place in Year 7 at a selective high school in New South Wales.

Selective schools dominate the top Year 12 results, and demand for places always outstrips supply. About 18,500 students sat the NSW selective high school test this year, for 4,200 spots next year.

The NSW government says gifted students “benefit both academically and socially” from learning alongside other students with similar abilities in selective schools. But there are few published studies on whether selective schooling pays off for individuals in terms of better outcomes later in life.

In the first research of its kind in Australia, our research tracked almost 3,000 young people from age 15 to 25 to see if there are longer-term benefits to attending a selective school.

Our results suggest the benefits are very minimal. Participants who attended selective schools reported higher general life satisfaction at age 25, but all other measures around employment and education were not significant.

What are selective schools?

Fully selective schools are public schools that enrol the top-performing students according to an entrance exam held each year.

They make up about 1% of government schools around Australia, but most are in NSW, which has 21 fully selective schools. Victoria has four, and Queensland and Western Australia have one each.

There are also 35 partially selective schools in Victoria and 24 in NSW. These schools enrol the majority of their students from the local area, but non-local students are selected for academically streamed classes.

Our research

We analysed data from the 2009 cohort of the Longitudinal Study of Australian Youth, which tracks young people as they move from school into further study, work and their adult lives.

The survey looks at whether academic performance was considered as part of a student’s enrolment into high school (always, sometimes or never). These were used as our measure for a school’s selective status.

We then used a statistical technique called “nearest-neighbour matching” to compare selective school students to their non-selective peers. This meant students had similar characteristics such as gender, socioeconomic status and reading and maths scores in Year 9 before we compared their outcomes as adults.

At 19, we looked at whether they had finished high school and to what extent they were studying or working. At age 25, we looked again at the extent to which students were working or studying as well as the number of years they had spent in education, and their general life satisfaction.

Our findings

At ages 19 and 25, there was no significant difference between selective and non-selective students in terms of whether they had graduated from high school, the extent to which they were working or studying, or the total number of years spent in education.

There was a slight difference in terms of general life satisfaction. General life satisfaction is measured using the average score after students were asked to rate factors such as how satisfied they were with their homes lives, jobs/careers, social lives, spare time activities, standard of living, independence and lives as a whole.

For 25-year-olds, those who attended a school that “always” applied academic selection (was fully selective) had greater general life satisfaction, on average, by 0.19 points. This was based on a scale of 0–10.

Weighing up the costs as well as the benefits

Selective school students have some of the highest Australian Tertiary Admission Rank (ATAR) scores. Unsurprisingly, many parents see a spot in a selective schools as a way to ensure future success, and spend a lot of time and money to try and secure a spot. Research also shows private tutoring is “booming”.

Along with the hope of academic success, one of the many reasons families want a selective place is they are seen as providing a more supportive and challenging environment .

But as Melissa Tham’s 2020 research showed, the experience of selective schooling is highly varied. Many students report positive experiences, but many also describe mixed or negative experiences to do with immense pressure, competition and stress on a daily basis.

More broadly, education researchers note there are big equity problems about selective schools. There may be no fees like at private schools, but selective school students are more likely to come from families who are university educated and work in professional jobs. This can concentrate disadvantage in non-selective schools.

We need more research

Our research suggests despite the hype, pressure and effort around getting a place at selective school, students are no more likely to go to university or be working by the age of 25.

Our results indicate they may have slightly greater life satisfaction, but we need more research and transparency around Australian selective schools to examine whether these schools benefit students.

More answers are crucial to the students and families who seek a selective education. They also matter to state governments who operate them and taxpayers who foot the bill.

If the supposed benefits are not proven, we should reconsider the purpose of selective schooling and whether they need to be scaled back.

Four years after the pandemic forced workers home, companies in New Zealand and elsewhere are summoning staff back to the office.

But office workers are not necessarily thrilled about the prospect. Recent research found returning to the office can negatively affect staff wellbeing. In particular, it can make many employees feel more stressed.

This adds to the decline in wellbeing many have experienced since the COVID-19 pandemic due to social distancing, isolation, daily uncertainty and fear. As a result, there has been an increase in people experiencing stress, anxiety, frustration, isolation and depression.

So how can organisations bring employees back to the office while taking their wellbeing into account?

The view trumps flash perks

Yoga classes? Onsite gyms? Childcare? When it comes to employee wellbeing, flashy perks seem less attractive for workers than a more basic but often overlooked one: a window with a good view.

In a survey of 1,614 North American office workers, over half said views of the outdoors were the number one perk they wanted. And 78% said it improved their happiness and wellbeing.

The survey participants valued office views more than other perks such as fitness facilities and cafeterias, or benefits such as onsite childcare.

But what is it about office window views that workers find attractive? Is it the overall vista? Or are there particular features within the view?

Focusing on the features

Many people believe natural window views (trees, grass) are good for workers and urban window views (buildings, streets) are bad. But that’s not what we found.

Our team analysed the office window views of hundreds of employees in the US who spend the majority of the working day inside.

We found even the small amount of outdoor exposure from an office window view can explain why a worker does – or does not – feel good at work.

But at the same time, the research found some – but not all – natural views are good for us. The same was true for urban views. Some urban views are good for workers, others are not.

What matters most for an employee’s psychological, physical, and job-specific wellbeing are the specific features of their office window view. Our research found the two view features most likely to boost wellbeing are what we termed “mystery” and “coherence”.

Mysterious views (think of a mountain range or a city in the distance) hide information and make people curious to explore more. Coherent views (think of a savanna or skyscrapers) look symmetrical and organised which helps people to make sense of the environment.

The two worst features for our wellbeing are “refuge” and “complexity”. Refuge views (think of dense shrubs or narrow dark alleys) are excellent hiding places for predators, which people prefer to avoid. Complex views (think of a tangled forest or crowded urban areas) offer many shapes and textures, which can be overwhelming.

A passive way to boost wellbeing

Our research shows improving office window views is an efficient intervention to enhance employee wellbeing. Many popular employee perks require training (mindfulness), a designated time or place (the company’s onsite fitness programmes and gym), or motivation to engage in the activity (showing up for those).

But window views are passive, they require no effort from employees, and operate on a more or less continuous basis.

The pandemic raised awareness of the importance of access to the outdoors. We often feel better when exposed to the outdoor environment. Our findings could help organisations “build back better” as offices reopen.

A growing number of organisations are already redesigning workplaces to give employees greater exposure to the outdoors. And an easy way to achieve this is with office windows. Many companies now have floor-to-ceiling windows throughout the building.

It is clear companies and their staff need to take a closer look at their window view. The features beyond the glass may explain why workers do – or do not – feel good at work.

Being “ghosted” – cut off from all communications without an explanation – isn’t a pleasant experience in any situation.

So when you’re in the middle of a job hunt – and may have poured your heart and soul into application forms and interviews – it can really sting.

A recent survey in the UK by hiring platform Greenhouse found that almost 45% of candidates had been “ghosted” by recruiters after an initial conversation.

Respondents from historically underrepresented backgrounds were significantly more likely to have been ghosted than white candidates.

But job-hunt ghosting seems to be happening in both directions. A recent Edge Recruitment survey of Gen Z job hunters in South Australia found that 15% had ghosted an employer once, and 34% had done it multiple times.

New recruitment technologies – such as online application forms and artificial intelligence for candidate screening – aim to maximise efficiency. But good communication is a two-way process, an important rule we seem to be forgetting.

So why are we ghosting each other, and what should recruiters and candidates do about it?

Why do candidates ghost?

Preferred communication styles have seen a shift in the workplace, particularly among Gen Z, those born between 1997 and 2012.

As digital natives, many have different attitudes towards workplace communications and career development than previous generations.

Gen Z employees really value immediate, meaningful feedback at work. But their tech-savviness means many prefer instant messaging, video conferencing, and collaborative tools for teamwork.

The etiquette around these tools is still evolving, and differs from that of phone calls and talking in person, where failing to reply immediately is almost unthinkable.

Read more:
Young people hate making phone calls – could it be hurting their careers?

There are other generational differences. Along with millennials, Gen Z are changing jobs more frequently than older generations.

This is in part due to the greater uncertainty and rapid changes in the modern workplace they have experienced as they’ve started their careers, making them less inclined to commit to a single employer long-term.

But this sense of having “options” could be contributing to “ghosting” behaviour, if it causes them to disengage suddenly when their values and expectations misalign with a prospective employer.

Why do recruiters ghost?

On the other side of the coin, modern technologies such as AI-supported candidate screening have streamlined much of the recruitment process for employers.

They’ve also made it easier for organisations to communicate with candidates anywhere, anytime.

So why is communication still breaking down? There are likely several factors at play.

For roles with a large number of applicants, recruiters often prioritise responding to a select few. This leaves many others ghosted simply due to time constraints, even if they’ve put considerable amounts of effort into applying.

The shifting needs of an organisation can also quickly change hiring priorities. Some positions may end up being redefined or put on hold in the middle of the hiring process, without immediate updates to those who’d applied.

Technical issues, like emails landing in spam folders, can lead to further unintended ghosting. As can poor communication between hiring managers and recruiters.

And unfortunately, some of it comes down to the emotional discomfort of rejection. Delivering clear rejection messages or communicating uncertain circumstances can be taxing for recruiters, prompting some to ghost out of avoidance.

This can be made worse if organisations have vague recruitment policies and weak accountability practices.

Setting our expectations

Establishing a clear road map of the recruitment process early on is crucial. Candidates should know what to expect and when.

While it may not eliminate ghosting entirely, better communication of both sides’ expectations can help avoid some of the hurt.

In a multi-generational work environment, communication preferences vary. Some people thrive in face-to-face meetings, while others prefer written communication for its clarity.

Potential job candidates, particularly from Gen Z, should directly voice their own communication preferences to recruiters early on – how they want to be contacted, and when. They should also seek to get a good grasp on the organisation’s own preferences.

Recruiters themselves need to recognise and adjust to the diverse communication styles that exist across their workforce (and those looking to join it). This means embracing various communication methods, and being willing to adapt to different candidate preferences and job contexts.

Formal emails, for example, remain ideal for significant announcements, whereas instant messaging is useful for quick exchanges that keep people in the loop.

Fostering healthy employment relationships begins at the recruitment stage. Employers should offer basic courtesy to everyone, even those who don’t ultimately progress further.

A strong sense of connection is important. A 2021 study found that greater communication with recruiters and more knowledge about a firm made candidates less likely to ghost.

The goal is a culture that values timely responses and establishes clear expectations – but can also adapt to the changing world of work.

At first glance, Keir Starmer’s Labour Party has just put in a performance for the ages in the British general election.

The incoming prime minister controls a comfortable parliamentary majority, Tory bastions have fallen to the left and the right, and any number of curtains have been brought down on the careers of Tory MPs and ministers.

Whisper it quietly, but the curtain might also have fallen on the electoral system that delivered Starmer his moment of triumph.

On closer inspection, in fact, there are several striking similarities between what has been going on at Westminster and the circumstances that led to the adoption of the Mixed Member Proportional (MMP) system in Aotearoa New Zealand in 1993.

A single-party state

Manufactured parliamentary majorities? Check. With the exception of 1951, every postwar election held in New Zealand under the old first-past-the-post (FPP) electoral system – the one they still use in the UK – produced a government comprising a single party voted for by a minority of voters but which controlled a majority of parliamentary seats.

Starmer’s Labour has won 63% of the 650 seats in the House of Commons on the basis of just 33.7% of the vote

Declining voter support for major parties? Check. In New Zealand, the proportion of all votes won jointly by the two parties that have dominated politics for the better part of a century, National and Labour, began falling in the 1970s. In 2023, they won just 65% of the vote between them.

On election day the UK Labour and Conservative parties picked up a miserable 57.5% of the vote between them. They may have been rewarded with 82% of all Commons seats, but their tides are going out.

Smaller parties rising in popularity but being punished by FPP? Check. Support for what we used to call minor parties here in New Zealand grew steadily from the 1970s and ‘80s, but under FPP was never rewarded with proportionate numbers of parliamentary seats.

Most famously, in 1981, Social Credit won 20% of the vote but just two seats. In the UK, the Liberal Democrats and Reform UK won more than 25% of the vote between them – and just 11% of parliamentary seats.

Disaffection and low turnout

Disaffected voters? Check. In New Zealand, much of the impetus behind electoral reform came from voters who had tired of an electoral system that stacked the odds in favour of the two large parties.

That system routinely delivered single-party majority governments (supported by a minority of voters) who were inclined to throw their executive weight around.

The disgruntlement was also reflected in declining rates of voting. Turnout in the UK was just 60% of eligible voters, the lowest since 2001. One estimate put turnout below 50% in 59 constituencies.

Governments out of touch? Check. The referendum that led to a new electoral system in New Zealand came after decades of executive obfuscation, arrogance and overreach from both Labour and National governments.

The UK’s Conservative government, which unleashed austerity on poor people, took its country out of Europe on dubious grounds, behaved disgracefully during a global pandemic, and tried to create a new form of macroeconomics in which neither the markets nor governing institutions had any faith, has just been put out of its misery.

Careful what you wish for

There is one final historical parallel. In New Zealand, the Electoral Reform Coalition – a loose alliance which lobbied for a new electoral system – provided a focus for citizens with differing and disparate reasons for feeling grumpy with the FPP electoral system.

There is an equivalent group in the UK, the Electoral Reform Society – coincidentally, led by former New Zealand Labour MP and minister Darren Hughes. The manifest disproportionality of the UK’s electoral rules has just given it some very good reasons to push harder for reform.

Consider what this UK election might have produced had it been held under New Zealand’s MMP system. Leaving aside the messy details of thresholds, coat-tailing rules and overhangs, Starmer would be leading a caucus of 219 MPs, not the 412 he actually has.

The Conservatives would have 154 seats (33 more than they won); the Lib Dems would have 79 spots. And Reform UK’s MPs would be sitting in 93 seats, not five, making Nigel Farage the leader of the third-largest party in the Commons.

In this world there is no Labour landslide. In fact, there is no parliamentary majority for Starmer at all – and perhaps no Labour government, which could not get to a parliamentary majority of 326 even with the support of the Lib Dems.

Neither, for that matter, could a Tory–Reform coalition. Instead, there would be a hung parliament and the prospect of a protracted process of government formation.

For many reasons, of course, things would have been quite different had the 2024 UK election actually been held under an MMP electoral system. But it bears saying, nonetheless, that with electoral law reform, as with most things, you need to be careful what you wish for.

There are renewed calls this week for the Australian government to implement a range of measures aimed at improving our diets. These include restrictions on junk food advertising, improvements to food labelling, and a levy on sugary drinks.

This time the recommendations come from a parliamentary inquiry into diabetes in Australia. Its final report, tabled in parliament on Wednesday, was prepared by a parliamentary committee comprising members from across the political spectrum.

The release of this report could be an indication that Australia is finally going to implement the evidence-based healthy eating policies public health experts have been recommending for years.

But we know Australian governments have historically been unwilling to introduce policies the powerful food industry opposes. The question is whether the current government will put the health of Australians above the profits of companies selling unhealthy food.

Diabetes in Australia

Diabetes is one of the fastest growing chronic health conditions in the nation, with more than 1.3 million people affected. Projections show the number of Australians diagnosed with the condition is set to rise rapidly in coming decades.

Type 2 diabetes accounts for the vast majority of cases of diabetes. It’s largely preventable, with obesity among the strongest risk factors.

This latest report makes it clear we need an urgent focus on obesity prevention to reduce the burden of diabetes. Type 2 diabetes and obesity cost the Australian economy billions of dollars each year and preventive solutions are highly cost-effective.

This means the money spent on preventing obesity and diabetes would save the government huge amounts in health care costs. Prevention is also essential to avoid our health systems being overwhelmed in the future.

What does the report recommend?

The report puts forward 23 recommendations for addressing diabetes and obesity. These include:

• restrictions on the marketing of unhealthy foods to children, including on TV and online

• improvements to food labelling that would make it easier for people to understand products’ added sugar content

• a levy on sugary drinks, where products with higher sugar content would be taxed at a higher rate (commonly called a sugar tax).

These key recommendations echo those prioritised in a range of reports on obesity prevention over the past decade. There’s compelling evidence they’re likely to work.

Restrictions on unhealthy food marketing

There was universal support from the committee for the government to consider regulating marketing of unhealthy food to children.

Public health groups have consistently called for comprehensive mandatory legislation to protect children from exposure to marketing of unhealthy foods and related brands.

An increasing number of countries, including Chile and the United Kingdom, have legislated unhealthy food marketing restrictions across a range of settings including on TV, online and in supermarkets. There’s evidence comprehensive policies like these are having positive results.

In Australia, the food industry has made voluntary commitments to reduce some unhealthy food ads directly targeting children. But these promises are widely viewed as ineffective.

The government is currently conducting a feasibility study on additional options to limit unhealthy food marketing to children.

But the effectiveness of any new policies will depend on how comprehensive they are. Food companies are likely to rapidly shift their marketing techniques to maximise their impact. If any new government restrictions do not include all marketing channels (such as TV, online and on packaging) and techniques (including both product and brand marketing), they’re likely to fail to adequately protect children.

Food labelling

Food regulatory authorities are currently considering a range of improvements to food labelling in Australia.

For example, food ministers in Australia and New Zealand are soon set to consider mandating the health star rating front-of-pack labelling scheme.

Public health groups have consistently recommended mandatory implementation of health star ratings as a priority for improving Australian diets. Such changes are likely to result in meaningful improvements to the healthiness of what we eat.

Regulators are also reviewing potential changes to how added sugar is labelled on product packages. The recommendation from the committee to include added sugar labelling on the front of product packaging is likely to support this ongoing work.

But changes to food labelling laws are notoriously slow in Australia. And food companies are known to oppose and delay any policy changes that might hurt their profits.

A sugary drinks tax

Of the report’s 23 recommendations, the sugary drinks levy was the only one that wasn’t universally supported by the committee. The four Liberal and National party members of the committee opposed implementation of this policy.

As part of their rationale, the dissenting members cited submissions from food industry groups that argued against the measure. This follows a long history of the Liberal party siding with the sugary drinks industry to oppose a levy on their products.

The dissenting members didn’t acknowledge the strong evidence that a sugary drinks levy has worked as intended in a wide range of countries.

In the UK, for example, a levy on sugary drinks implemented in 2018 has successfully lowered the sugar content in UK soft drinks and reduced sugar consumption.

The dissenting committee members argued a sugary drinks levy would hurt families on lower incomes. But previous Australian modelling has shown the two most disadvantaged quintiles would reap the greatest health benefits from such a levy, and accrue the highest savings in health-care costs.

What happens now?

Improvements to population diets and prevention of obesity will require a comprehensive and coordinated package of policy reforms.

Globally, a range of countries facing rising epidemics of obesity and diabetes are starting to take such strong preventive action.

In Australia, after years of inaction, this week’s report is the latest sign that long-awaited policy change may be near.

But meaningful and effective policy change will require politicians to listen to the public health evidence rather than the protestations of food companies concerned about their bottom line.
