Australia’s freshly elected parliament is hashing out the details of Labor’s Climate Change Bill, which would enshrine an emissions reduction target into federal law. The Greens have the numbers to block the bill in the Senate, and are likely to seek concessions from Labor in return for their support.

Labor has already ruled out the demand to ban new coal and gas projects, saying this would devastate the economy. But Labor did not rule out another Greens policy: introducing a “climate trigger” into Australia’s environment law.

Under that proposal, future projects – such as a new mine or high-emissions industrial plant – would be assessed on the climate harms they’d potentially cause.

Let’s take a closer look at how the climate trigger would work, what it would achieve and, crucially, how it could help Australia reduce emissions.

What is the climate trigger?

To understand the proposed climate trigger, we should first outline the federal government’s role in assessing and approving new projects under Australia’s national environment law, the Environment Protection and Biodiversity Conservation (EPBC) Act.

The government’s role under the act is to assess the impacts of proposed projects on “matters of national environmental significance”. There are nine designated matters, including threatened species, wetlands of international significance and world heritage sites.

If a project is likely to have a significant impact on one of these matters, then the environmental impact assessment and approval scheme is “triggered”.

Surprisingly for legislation intended to protect the environment, climate change is not presently designated as a matter of national environmental significance. This means it’s considered only indirectly, such as how climate change impacts might harm a protected wetland or a threatened species.

The proposed climate trigger would add climate change to the list, and allow it to be dealt with head on.

In practice, this means the impacts of a proposed project on the climate would be thoroughly assessed, and then weighed in the environment minister’s final decision on whether the proposal should be approved.

Past climate trigger proposals

The climate trigger is not a new idea. In fact, when the EPBC Act was first introduced in 1999, the then environment minister sought to develop a greenhouse gas trigger. Nothing eventuated from that commitment.

In 2005, Anthony Albanese, then the shadow environment minister, introduced the Avoiding Dangerous Climate Change (Climate Change Trigger) Bill, but this also did not proceed.

And in 2020, the Greens introduced a climate trigger bill in the Senate which lapsed with the last parliament. The Greens’ new bill will presumably be based on this one.

Meanwhile, a major independent review of the EPBC Act in 2020 by Professor Graeme Samuel did not support a climate trigger on the basis that reducing emissions is best left to other policies and programs.

Professor Samuel did, however, say new projects should fully disclose all potential emissions as part of the assessment process. He did not elaborate on how this should be treated in approval decisions.

What could it achieve?

The climate trigger could be defined in terms of an emissions threshold, or by reference to emissions intensive activities, or by some combination of these. It could, for example, require any development likely to produce over 100,000 tonnes of carbon dioxide equivalent per year to be assessed under the act.

Coal mining and gas extraction are significant contributors to Australia’s domestic emissions.

Australia’s net-zero plan fails to tackle our biggest contribution to climate change: fossil fuel exports

Approving more of these projects will not only make it harder for Australia to meet its climate targets, but also, is completely contrary to the goals of the Paris Agreement. Limiting global warming to 1.5℃ above pre-industrial levels this century means putting a stop to new coal and gas.

Australia is the third largest exporter of fossil fuels, behind Russia and Saudi Arabia. Our fossil fuel exports account for more than double our direct emissions. Labor’s emissions reduction targets do not address these downstream emissions.

A climate trigger would see Australia stepping up to take some responsibility for the total emissions from such fossil fuel export projects, including the emissions from burning coal and gas overseas.

Even if new fossil fuel projects are given the go ahead, requiring proponents to disclose emissions through the assessment process would make it possible to regulate these emissions using conditions on approvals.

This would help to address significant problems with new mine proponents underestimating their emissions.

Depending on how it’s framed, a climate trigger could also play a role in regulating emissions from other sources, such as land clearing.

Why we should be cautious

There are two reasons to be cautious about what a new climate trigger might achieve.

First, a climate trigger would require only projects which trigger the act to be assessed and a decision made on approval. This is well short of demands by Greens and others to halt new fossil fuel extraction projects.

We could expect that the climate trigger would make proponents think carefully about emissions before submitting their projects for approval. But the trigger would not of itself prevent new fossil fuel projects from being proposed and approved.

If the desired result is to stop new coal and gas, there are better and more direct ways to legislate for this result.

1 in 5 fossil fuel projects overshoot their original estimations for emissions. Why are there such significant errors?

Second, the EPBC Act is widely acknowledged as failing to protect matters of national environmental significance. It has failed to protect threatened species, world heritage sites and internationally recognised wetlands – all of which have been “triggers” under the legislation since 1999.

Adding a new climate trigger to an already failing EPBC Act may not achieve very much without additional reforms.

This includes implementing national environmental standards, as recommended by Professor Samuel, and introducing a national Environment Protection Agency to enforce the act, as promised by the Albanese government.

Arguably, proposals for a climate trigger should be dealt with as part of this larger overhaul of the act.

Labor has introduced its controversial climate bill to parliament. Here’s how to give it real teeth

Still, a climate trigger could bring some real teeth to the government’s proposed Climate Change Act, whether introduced as a stand alone amendment to the EPBC Act or as part of wider reforms expected next year.

Perhaps most importantly, a climate trigger would also be a step toward Australia recognising the global harm caused by fossil fuels extracted in Australia, and the need to take greater responsibility for deciding whether these projects should be allowed to proceed.

As Rolling Stone wrote last month, “for at least the past decade, Beyoncé Giselle Knowles-Carter has been the world’s greatest living entertainer.”

The African-American pop star has reached single-name fame status like other mega pop stars Madonna, Cher, Britney and Adele.

Her long-standing and extremely successful career within girl group Destiny’s Child (1990-2006) and as a solo artist (2003-present) has been filled with pop cultural “moments” and record-breaking releases.

As I have written elsewhere, Beyoncé’s stardom is an interesting form of world-building. World-building, or “worlding”, is the ongoing construction and maintenance of stardom by creating an intimate, identifiable, holistic world around the star – not just a singular star image.

The audience is in on Beyoncé’s world-building the same way we watch a film. We know it is “made-up” but we want to believe it’s real – or at least go along with it for the ride.

Beyoncé World

Our obsession with celebrity is centred around the “search” for the “authentic” person behind the manufactured persona in pop videos.

The Beyoncé (2013) visual album was a sign of the increasing personal intimacy of Beyoncé’s stardom, and her transition to the active creation and ownership of an intimate, identifiable and holistic world.

“Beyoncé World” is created and maintained primarily through Beyoncé’s music videos and visual albums, but also across her concerts, performances and public appearances, and her social media accounts and website.

Other contemporary pop stars construct an “authentic” star image through sharing intimate details of their lives via social media or semi-autobiographical albums and music videos.

But Beyonce’s social media posts are notoriously curated and tight-lipped about her private life.

She rarely posts captions and favours fashion photoshoot images of herself rather than “authentic” makeup free selfies (although she wrote a long caption to launch the Renaissance album – a rarity).

Lemonade
(2016) was Beyoncé’s most personal album. It addressed the infidelities of her husband, rapper and music mogul Jay-Z, as well as her own personal outrage at racial injustices in the United States.

Beyoncé World is not the messy, no-makeup selfies or confession videos of other stars. It is a more curated, high fashion, high art, high concept world for fans to participate in.

Taking care of the Beyhive

Beyoncé’s work always makes a splash but her seventh solo album, Renaissance, leaked online 36 hours before its scheduled release. Fans in France were able to buy CD versions two days before its scheduled release.

But Beyoncé has such a loyal fanbase some of her die-hard fans (called the “Beyhive”) thought it was blasphemous to listen earlier than Queen B had intended, posting instructions on social media to wait it out.

If it’s Beyoncé’s world, you need to play by Beyoncé’s rules, and the Beyhive are a key cornerstone of maintaining these rules.

Being “in the know” about specific visual and musical references the star makes (in every single output) helps fans enter into the world-building process – and they certainly want to interpret her art the way she intended it.

Her past two solo albums were both surprises: the internet-breaking digital drop Beyoncé, and the politically charged celebration of Black women in Lemonade. (She also directed, wrote and produced the film/visual album and celebration of Black Excellence, Black is King in 2020, to accompany The Lion King remake.)

Renaissance has received more of a traditional marketing buildup.

The lead single, Break My Soul, was released on June 21, and the full tracklist and album cover were posted on her Instagram before the album’s release.

While she has been teasing the album’s imagery for months, some were hoping for a visual album – or a music video for every song on the album – like her two previous solo releases.

Beyoncé has yet to release any music videos for Renaissance, other than lyric-only videos. This either means the star is about to release a Renaissance visual album or has bigger plans for a longer music film project.

Beyoncé’s Lemonade: tell all or fizzy, soap-operatic art object?

Renaissance woman

Renaissance is Beyoncé’s first solo album in more than five years, and her first fully dance album.

A large part of her success is due to her ability to constantly reinvent herself and her music, borrowing from all genres and collaborating with a range of hit-makers and unusual musical artists.

Renaissance covers numerous genres, referencing many musical touchstones and pays an important homage to African-American dance music creators and LGBTQI+ dancehall culture.

The album includes nods to 1970s disco queen Donna Summer and New Orleans bounce-music icon Big Freedia, as well as a collaboration with Grace Jones on the track Move.

Renaissance traverses disco, funk, techno, hip-hop, house, dancehall, Afrobeats and ballroom. Aside from Jones, Beyoncé has worked with a wide range of collaborators including Drake, The-Dream, Honey Dijon, Skrillex, Syd, Hit-Boy, Mike Dean and A.G. Cook, among others.

While Renaissance celebrates diversity in dance music, the star has been called out for using an ableist slur in the song Heated, and has now announced she will remove the lyric. It might be Beyonce’s world, but that doesn’t mean she won’t listen to her fans.

Lemonade came out during a time of great political upheaval in America and directly addressed the Black Lives Matter movement. Renaissance is less overtly political and more a celebration of a post-pandemic opportunity to hit the dance floor. She hopes it inspires fans to “release the wiggle”.

Beyoncé World is not just created by the star and her team, but also by fans connecting the dots between her social media, her website, Renaissance and their own real world.

They’ll know not to take this album too seriously, and to imagine themselves on the dancefloor with Queen B.

On July 23, World Health Organisation Director-General Tedros Adhanom Ghebreyesus took the unprecedented step and declared the monkeypox outbreak a “public health emergency of international concern” – the highest global alert level for a disease outbreak.

Following this and with 45 cases in Australia, Chief Medical Officer Paul Kelly declared last week that monkeypox is now a “communicable disease incident of national significance”.

So what is monkeypox? And who’s eligible for a vaccine?

Most cases in the current global outbreak are occurring among men who have sex with men. How can this group and others who are at risk protect themselves?

What is monkeypox?

Monkeypox is not a new disease, it was found in the late 1950s in lab primates in Denmark, and was first diagnosed in humans in an infant in the 1970s in the Democratic Republic of Congo.

In the past, monkeypox has mainly been transmitted from infected animals to humans (it is a zoonotic disease), and has been endemic to West and Central Africa. Transmission can occur through contact with infected animals including rodents, mice, rats, squirrels, monkeys and other primates.

But in this outbreak we’re seeing human-to-human transmission.

There are two distinct strains of monkeypox. These are the Central African and the West African types, the latter of which is believed to be one linked to the current global outbreak.

According to US Centers for Disease Control and Prevention (CDC) data, 23,620 cases have been reported since May in 80 countries, with 73 countries that had no previous reported monkeypox cases.

There have been at least seven deaths.

Most of the cases in Australia have been in New South Wales and Victoria, among returned travellers and men who have sex with men, and in the age group 21-40 years.

The declaration that monkeypox is now a disease of national significance means the outbreak requires national policies, interventions and public health messaging, with the deployment of more resources to assist affected areas and groups most at risk.

Symptoms and transmission

The incubation period – the time taken to develop the disease after exposure to the virus – is usually around 6-13 days.

Transmission generally requires close contact with an infected person. It can be transmitted via respiratory droplets.

It can also be transmitted through direct contact with body fluids or the rash (“lesions”), often through skin-on-skin contact, or indirect contact such as through contaminated clothing or bedding.

Transmission may occur from people without symptoms, or with barely-detectable symptoms.

Symptoms are similar to smallpox, though less severe. They can include:

• fever
• headache
• aches
• fatigue
• sweats and chills
• cough and sore throat
• a rash that can look like blisters or pimples, which can be painful. These “lesions” typically go through several stages before eventually falling off.

The CDC says most people who get the virus will develop the rash.

A study in the British Medical Journal published last week also found 88% of 197 people with monkeypox in London had lesions on their genitals or anus.

Symptoms generally last between two and four weeks, and the disease usually resolves on its own. Most adults with a healthy immune system won’t have severe illness and won’t experience long-term harmful effects.

There’s no specific treatment for monkeypox yet. People with the infection should be given supportive treatment and light dressings on the rash, depending on the symptoms. Antivirals such as “tecovirimat” have been made available to patients in some countries who have or are at high risk of severe disease, such as being immunocompromised.

People with the infection should isolate immediately for the duration of the illness – usually two to four weeks, until the lesions heal.

Higher risk groups

Monkeypox can affect anyone. But men who have sex with men are at higher risk at the moment. WHO Director-General Tedros Adhanom Ghebreyesus said 98% of cases so far are among men who have sex with men.

It’s important we provide as much information about the virus as possible, and it’s absolutely crucial we do this in a way that is not stigmatising.

This outbreak is seeing cases spread via close prolonged contact from sexual activity in the LGBTIQ+ group. Many from this group want to take proactive actions to help their community.

Specific actions governments can take include:

• prioritising vaccines as a matter of urgency for those most at risk
• targeting public health messaging so the LGBTIQ+ community can make informed decisions.

Actions individuals can take include:

• maintaining contact details of sexual partners in case of need to follow up
• avoiding sex if you have a rash until you get tested
• considering avoiding skin to skin contact during large gatherings
• if diagnosed with monkeypox, avoiding close physical contact, including sexual contact, with other people for the duration of the illness.

The CDC says condoms may help lower the risk of spread if the lesions are confined to the genital and/or anal region, but they’re likely not enough to prevent transmission on their own.

Monkeypox: ‘This is an entirely new spread of the disease’

Who should have the vaccine?

Australia has secured small supplies of two smallpox vaccines, which provide protection against monkeypox.

The vaccine advisory body, the Australian Technical Advisory Group on Immunisation (ATAGI), has recommended key risk groups be administered the vaccines. They include:

• those identified as a high risk monkeypox contact in the past 14 days
• men who have sex with men who are at high risk of exposure. This includes those living with HIV, or with a recent history of a high number of sexual partners or group sex
• sex workers, with clients in high-risk categories
• and anyone in the risk categories planning travel to a country experiencing a significant outbreak, with vaccination recommended four to six weeks prior to leaving.

ATAGI has stated that vaccination within four days of exposure to someone who’s infectious with monkeypox will provide the highest chance of preventing disease.

Avoiding close contact with people who have the infection can help prevent transmission. Monkeypox doesn’t spread as easily as the coronavirus and can be kept under control if we are cautious.

The need for vaccine equity and global health leadership

We can’t repeat the “vaccine nationalism” we’ve seen during COVID with rich countries hoarding vaccine doses, as this will unjustly prolong the outbreak.

Currently, according to The Lancet medical journal, a smallpox vaccine sold as “Jynneos” in the US costs around US$100 a dose. The WHO has called on countries and manufacturers to ensure the vaccines, as well as diagnostics and therapeutics, are made available “at reasonable cost” where most needed.

Thus we have major political and policy challenges ahead and will need strong global health leadership going forward.

In its plan to retool the economy, the New Zealand government highlighted green hydrogen as a game-changing fuel. It can indeed be used to make climate-friendly fertilisers and steel or to power some modes of transport that aren’t suited to batteries.

But to provide a buffer against the volatility of overseas markets, Aotearoa would need to be as energy independent as possible. Ideally, this would mean consuming only green hydrogen produced here, using abundant renewable hydro, wind and solar resources.

A hydrogen economy is good in theory, but to make the switch at the scale of Aotearoa’s climate ambitions would require about 150 petajoules of hydrogen each year, according to one estimate. That’s about a quarter of our current energy use.

Hydrogen is produced in a process known as hydrolysis – the splitting of water into hydrogen and oxygen gas, using electricity. To produce a quarter of Aotearoa’s energy consumption, hydrolysis would consume an enormous amount of water, about 13 million tonnes each year, the equivalent of a month’s worth of Auckland’s water demand.

This raises both cultural and technical issues, which we must address before embarking on a transition to hydrogen as a green fuel.

Breakthrough in gas separation and storage could fast-track shift to green hydrogen and significantly cut global energy use

Consuming water has cultural implications

Freshwater has enormous significance to iwi and hapū. However, their views on hydrolysis as a consumptive use of water are not widely understood. If cultural complexity is ignored, hydrogen infrastructure or processes may fail to achieve an appropriate fit within Aotearoa New Zealand society and the technology could be orphaned.

Instead, we could start addressing this early through wānanga with representatives from a wide range of potentially affected iwi. Recognising and addressing cultural concerns at the outset will allow Māori to shape how the technology is developed and to share in the economic benefits of a hydrogen economy. The intention is to better understand how green hydrogen technologies and infrastructure could belong in Aotearoa New Zealand.

Supposing we are willing and able to make this vast quantity of hydrogen, our experience with other fuels suggests we would need about a month’s worth in storage at any given time. Storage helps to smooth fluctuating market demand, takes advantage of seasonal excess of renewables (in very windy, very sunny weeks) and provides emergency reserves for “dry year” crises.

Storing hydrogen underground

Unfortunately, hydrogen can’t be stored as a liquid except in specialised containers that keep it at extremely low temperatures. Like a freezer, this is always consuming energy.

Hydrogen could be kept in special high-pressure tanks, but we would need more of these tanks than we have people in New Zealand. These tanks would be costly, cover large tracts of productive land and would be prone to damage by natural hazards. Where would they all go?

Scientists have been looking at the possibility of storing hydrogen underground, in great caverns carved in salt or in old oil and gas fields.

We already do this with natural gas in Taranaki. When it’s not needed, gas is injected into an old field called Ahuroa and then extracted as required. Underground storage of gas (methane) is common practice, providing energy resilience. For example, given the disruptions caused by the war in Ukraine, Germany is accelerating gas storage in geologic reservoirs in time for winter.

Green hydrogen is coming – and these Australian regions are well placed to build our new export industry

We have recently shown there may be enough space in other Taranaki rock reservoirs to store hydrogen underground. But it won’t be easy.

We know the gas can react with certain kinds of rock. It can even be a meal for hungry microbes. Both these processes would consume a valuable fuel. But predicting whether they will happen requires special laboratory experiments that can replicate the extreme pressure and temperature three kilometres below ground.

We are also still learning how to predict how hydrogen will move underground. We know that some of the injected gas will never come back out. This is the “cushion” that acts a bit like a spring that pushes the other hydrogen back to the surface.

Some hydrogen may also escape into the atmosphere through small cracks in the rock. We’ll need to know how much, set up surveillance to watch for it and consider its effect on the climate.

These are just a few of the challenges posed by underground storage of hydrogen. But our experience with natural gas storage gives us confidence we can manage them with the right research and planning.

Don’t rush into a hydrogen economy until we know all the risks to our climate

Making it work

New Zealand’s hydrogen future remains uncertain, but work is underway to prepare. Early signs for underground storage of green hydrogen are promising and there’s lots of enthusiasm for it overseas.

But technical feasibility is not enough: any solution must make economic sense and be acceptable to the wider public, particularly tangata whenua.

Proving the feasibility of any new idea takes time. We need to develop, sometimes fail, refine and then find success. But with each new extreme weather event, its clear we don’t have a lot of time. In this new era of adaptation, governments, industry, communities and scientists will need to work more closely than ever.

The deaths of more than 50 Ukrainian prisoners of war last week is not only an apparent war crime, but also another sign the situation is becoming a race to the bottom when it comes to international law and conventions.

Ukraine and Russia have blamed each other for the attack on the prison in Russian-occupied Donetsk. Ukraine also claims prisoners were being tortured and murdered there. Russia’s British embassy later posted on Twitter that Ukrainian Azov battalion soldiers deserved a “humiliating death” by hanging.

But amid the accusations and counter-accusations of atrocities being committed against prisoners of war, some simple facts are easily overlooked: rules already exist to prevent such horrors, and they apply in Ukraine.

Prisoners of war are explicitly covered by the Third Geneva Convention, drawn up in 1949 to replace the old Prisoners of War Convention of 1929 after the awful lessons of the second world war.

Both Russia and Ukraine are signatories, meaning they have promised to respect it in all circumstances. It’s important to note this is not the protocol of the Geneva Conventions Russian President Vladimir Putin recently quit.

Fog of war

Restraint during a war isn’t easy, but it is essential nonetheless. As well as respecting basic humanity and honour, the rules – which have operated for over 100 years – help combatants build the confidence to eventually find peace.

In the sense that it helps avoid escalating revenge and reprisal for attacks against the defenceless, respect for prisoners of war is also a pragmatic act of self-interest.

Adherence in Ukraine to the fundamental conditions of the Geneva Convention has been hard to gauge, however. Apart from occasional exchanges of prisoners of war, exactly how many prisoners have been taken by each side, and where they are held, remains largely unknown.

Read more:
Russia says peace in Ukraine will be ‘on our terms’ – but what can the West accept and at what cost?

While the Red Cross has been able to visit some POWs and other detainees, it has not been granted access to visit them all. The problem is compounded by claims that some combatants taken on the battlefield are mercenaries and therefore do not count as prisoners of war, meaning they may be executed.

Further complicating things is that both sides are promising to put prisoners on trial for war crimes. With Russia holding over 1,100 Ukrainian prisoners and Ukraine making over 15,000 allegations of war crimes, both parties need to publicly re-pledge to the Geneva Convention on prisoners of war before things escalate.

Rights of the prisoner

The basic rules governing the treatment of prisoners of war are simple enough to state:

• they must be taken prisoner if they surrender unconditionally, cannot be executed if they have stopped fighting, and must not be subjected to reprisals, mutilation or torture

• they may be questioned (name, rank and serial number) but must be humanely treated and protected against acts of violence or intimidation, and against insults and public curiosity

• they must be evacuated as soon as possible after capture to a safe area outside the combat zone, and can’t be used or positioned to deter military operations by their own side

• the location of prisoner-of-war camps should be shared, and the camps clearly marked to be visible from the air, so they are not bombed by mistake

• prisoners’ whereabouts should be shared via a central tracing agency, and they must be allowed to send and receive letters.

Read more:
Ukraine crisis: how do small states like New Zealand respond in an increasingly lawless world?

Beyond these rules, representatives from third-party countries or the Red Cross should be permitted to visit and interview (without witnesses) prisoners and their legal representatives.

And any disputes about the application of the convention rules should be resolved through an enquiry by an independent third party.

War trial risks

It’s the handling of war trials in particular that requires most restraint. Although prisoners cannot be tried simply for fighting against their enemy, the Geneva Convention allows trials for grave breaches of the laws of war (such as murder or torture) – and even the death penalty if the domestic law of the detaining power includes it.

And despite judicial safeguards relating to fairness and the rights and means of legal defence, there is still the risk of a tit-for-tat process: one side finds a prisoner guilty, the other side responds in kind.

Russia’s blockade could cause mass famine beyond Ukraine – but it’s a crime without a name

The best way through this is to allow the International Criminal Court (already pursuing its own investigations into the situation in Ukraine) to take the lead, giving the process real independence and integrity.

Trouble is, Russia has withdrawn from the International Criminal Court – just another measure of how far the observation of the laws of war has been eroded in Ukraine.

Pauline Hanson’s recent dramatic outburst and walkout from parliament as an Acknowledgement of Country was delivered has been condemned as racist and ignorant.

Social media sites reporting this incident have attracted a barrage of negative comments perpetuating misconceptions around Acknowledgement of Country and Welcome to Country. Many clearly do not understand what they are and see them as “special treatment”. Unfortunately, Hanson has been a source of this line of thinking around so-called “special treatment”, as seen in her 1996 maiden speech to parliament.

Such comments reveal an Australian society still burdened with an unfounded resentment and fear of Aboriginal rights and connection to Country.

So, what is an Acknowledgement of Country? How is it different to a Welcome to Country?

The courage to feel uncomfortable: what Australians need to learn to achieve real reconciliation

What is an Acknowledgement of Country?

An Acknowledgement of Country is often made at the start of an event to pay respect to First Nations peoples as the Traditional Owners and ongoing custodians of the land.

An Acknowledgement often highlights the unique position of First Nations people in the context of culture and history, and their intimate relationship with the land.

An Acknowledgement does not exclude anyone. Anyone can deliver one. It costs nothing to give or listen to. You lose nothing from a ten second acknowledgement of the Country, language, and people that existed in a place for tens of thousands of years.

An Acknowledgement does not impact on the rights and status of other Australian people.

‘Don’t read the comments’: misinformed and malicious comments stifle Indigenous voices

What is a Welcome to Country?

Acknowledgement of Country is different to a Welcome to Country. Crucially, only Traditional Owners can deliver a Welcome to Country.

Traditionally, First Nations people travelling to different Country had to seek permission to enter from the Traditional Owners. If granted, permission was given by way of a Welcome to Country.

Today, inviting an Elder to perform a Welcome is a way to recognise unceded Aboriginal sovereignty of ancestral lands. It’s also a way to honour ancient and continuing First Nations customs.

Wurundjeri Elder Joy Murphy Wandin has described Welcome to Country as practised by her people:

When there was a request to visit Country, the Werrigerri (a young man selected by the Elders of the community) would go on behalf of the community under the voice of the Elder, the Nurungeeta. There would be this negotiation and that could take a long time, it could take months. So that is the background of Welcome to Country. It is not a new thing. It is not because our land was dispossessed; it has nothing to do with that. It is all about respect for our culture and who we are. It is paying respect, especially to our ancestors.

Acknowledgements and Welcomes to Country weren’t invented to divide First Nations and non-Indigenous people.

Although both have been widely revived in recent years, they are traditional protocols. When Aboriginal peoples travel from their own home Country to that of another Aboriginal group, they too acknowledge the traditional custodians.

Similarly, it’s standard practice for a hosting First Nations group to perform a welcome to all visitors – Indigenous and non-Indigenous alike – as a way of being inclusive and welcoming.

In doing this, Aboriginal people are sharing their culture and social protocols and offering the opportunity to feel a deeper connection to the lands you walk upon and visit.

By learning traditional place names, you unlock important information about the character or features of that place.

Restoring and maintaining connection to Country

Many Aboriginal people have been removed from Country, or can no longer access it through development, private ownership, farming and mining.

The Stolen Generations and mission era systematically worked to eradicate Aboriginal languages and cultural traditions. For many First Nations peoples, Acknowledgement of Country can help to restore some of this severed connection to Country and identity.

As Professor Mick Dodson explains:

For us, Country is a word for all the values, places, resources, stories, and cultural obligations associated with that area and its features. It describes the entirety of our ancestral domains. While they may all no longer necessarily be the titleholders to land, Aboriginal and Torres Strait Islander Australians are still connected to the Country of their ancestors and most consider themselves the custodians or caretakers of their land.

For some Aboriginal people, Acknowledgement of Country is a constant reminder of the responsibilities of custodians to advocate for the protection of a fragile environment and its cultural heritage.

It reminds us all Aboriginal languages were the first languages spoken in this country. Many are are still spoken. Acknowledgement of Country brings us together and recognises the shared cultural history and landscape we have all inherited.

Joy Murphy Wandin, describes it as:

a very important way of giving Aboriginal people back their place in society, and an opportunity for us to say, “We are real, we are here, and today we welcome you to our land”. It’s paying respect, in a formal sense, and following the traditional custom in a symbolic way.

Understanding what Acknowledgement of Country and Welcome to Country are, and their history and origins can help us recognise the importance and power of continuing these practices.

It’s not about being divisive. It’s about continuing ancient connections to Country, history, and ancestors. It’s a reminder of the responsibility of custodians to the land and its creatures; to protect and look after them.

It’s about honouring and being respectful towards a custom and way of thought much older than the name or concept of “Australia” as a nation state, or any sitting of parliament.

At every federal election, there is a moment when election-watchers turn their attention to the seat of Eden-Monaro in New South Wales. Between 1972 and 2013, the party that formed government won Eden-Monaro. It was (and for some, still is) considered a bellwether seat – what happens in Eden-Monaro is representative of the Australian electorate at large.

But there is another election bellwether we never hear about: people experiencing homelessness. Taken as a group, those who experience homelessness are representative of multiple forms of disadvantage and marginalisation.

Yet this is a very diverse group of people. While rough sleepers are the most recognisable, homelessness encompasses living in overcrowded accommodation, couch surfing, and being forced to sleep in cars, caravans or tents.

What’s in the name ‘homeless’? How people see themselves and the labels we apply matter

Homelessness in Australia

On any given night, an estimated 116,000 people experience homelessness in Australia. It would be natural to assume that for those affected, finding a home is far more important than voting in an election. Yet the assumption that the need for housing supersedes the need to belong to a political community is not always true. Material needs and the need to belong co-exist and are interdependent.

Beyond the older, single, white male who typifies representations of homelessness, there are disproportionate numbers within this group of unhoused Aboriginal and Torres Strait Islanders, young people, older women, war veterans, ex-prisoners, people who were in out-of-home care as children, people with disabilities, and LGBTIQ+ communities.

People experiencing homelessness commonly also present with trauma, experience of family and domestic violence, and mental health concerns. Compounding this is the current housing crisis, where entirely new groups are entering homelessness service systems.

What our research showed

Working with the Australian Electoral Commission (AEC) and three specialist homelessness service providers in Adelaide over the 2019 federal election, we undertook one of the largest studies of homelessness and voting habits.

With 164 participants, our research demonstrated that while people experiencing homelessness have much lower enrolment and turnout rates than the general population, this is not due to lower levels of political interest.

In fact, we found political interest among this group was higher in some respects than the general population. As one of the participants in our study said about the act of voting:

That was one of the main things for me, the politicians knowing that okay, we are constituents, members of society, the homeless are actually coming out to vote, that my vote matters.

With a turnout rate in excess of 90% of enrolled voters, Australia has one of the most equitable electoral systems in the world. However, estimating the turnout rate for people experiencing homelessness is considerably more difficult. Data from small sample interactions – unhelpfully – places turnout at between 10 and 67%.

Disillusionment, not apathy

Our study did not attempt to definitively measure the turnout rates of people experiencing homelessness, though about a fifth of our participants reported voting regularly.

Despite the many barriers and disincentives to voting for this group, we found that disillusionment was the real problem. Most participants cared about voting and were interested in elections, but did not vote because they thought it was pointless. As one participant told us:

Why should we vote for someone who doesn’t want us? Who doesn’t want to look after us? […] All of us felt left out, we felt like we’re nothing. And we’re human beings, not animals to walk on just because we’re poor.

Those exit-polled at AEC pop-up booths at specialist homeless services expressed similar sentiments:

I felt sad […] I looked at those pieces of paper and I folded them up and I put them in the box and I walked away in disgust.

Over 80% of our participants said that voting was important yet most of them did not vote, and those who did reported mixed feelings about their electoral participation.

This reflects broader and deeper issues with political representation, especially of people experiencing disadvantage. Voting is how citizens assert their equality with other citizens, make their voices heard, and protect themselves from government neglect. As political scientist Walter Dean Burnham once said: “if you don’t vote, you don’t count”.

Increasing participation

Our study identified numerous ways electoral commissions can improve turnout for those experiencing homelessness. This includes permitting specialist homelessness service providers to be listed as residential addresses. This would allow homelessness service users to enrol and vote in the communities where they have meaningful connections.

We also recommended that any legislative, procedural, or operational changes, such as changes to voter identification requirements or enrolment processes, consider the potential impact on people experiencing homelessness.

However, the disillusionment with the political system felt by many experiencing homelessness is more serious and harder to tackle because it is informal and cultural.

The irony, of course, is that higher levels of electoral participation would make it harder for mainstream parties to ignore the needs, concerns and priorities of the most marginalised.

Being counted matters. We should do everything we can to ensure access to voting, the basic democratic right that protects and enhances all other rights.

New Zealand may seem to be under meteor bombardment at the moment. After a huge meteor exploded above the sea near Wellington on July 7, creating a sonic boom that could be heard across the bottom of the South Island, a smaller fireball was captured two weeks later above Canterbury.

Fireballs Aotearoa, a collaboration between astronomers and citizen scientists which aims to recover freshly fallen meteorites, has received a lot of questions about these events. One of the most frequent is about the bright green colour, and whether it is the same green produced by auroras.

Green fireballs have been reported and filmed in New Zealand regularly. Bright meteors often signal the arrival of a chunk of asteroid, which can be anywhere between a few centimetres to a metre in diameter when it comes crashing through the atmosphere.

Some of these asteroids contain nickel and iron and they hit the atmosphere at speeds of up to 60km per second. This releases an enormous amount of heat very quickly, and the vapourised iron and nickel radiate green light.

But is this the same as the bright green of an aurora? For the most recent meteor, the answer is mainly no, but it’s actually not that simple.

The colours of a meteor trail

The green glow of the aurora is caused by oxygen ions in the upper atmosphere, created by collisions between atmospheric oxygen molecules and particles ejected by the sun.

These oxygen ions recombine with electrons to produce oxygen atoms, but the electrons can persist in an excited state for several seconds. In an energy transition known as “forbidden” because it does not obey the usual quantum rules, they then radiate the auroral green light at 557nm wavelength.

A meteor can also shine by this route, but only if it’s extremely fast. Very fast meteors heat up in the thin atmosphere above 100km where auroras form.

Are the northern lights caused by ‘particles from the Sun’? Not exactly

If you want to see a green auroral wake from a meteor, watch out for the Perseid meteor shower, which has now started and will peak on August 13 in the southern hemisphere.

Also arriving at about 60km per second, the Perseids are extremely fast bits of the comet Swift-Tuttle. Some Perseids trail a beautiful, glowing and distinctly green wake behind them, particularly at the start of their path.

Once the Canterbury meteor hit on July 22, the capricious winds of the upper atmosphere twisted the gently glowing trail, resulting in a pale yellow glow towards the end (as seen in the GIF below, also recorded by Greg Price for an earlier meteor). This is caused by sodium atoms being continually excited in a catalytic reaction involving ozone.

Are we being bombarded by meteors?

Yes and no. The arrival of big, booming green meteors and the dropping of meteorites isn’t rare in New Zealand, but it is rare to recover the rock. Fireballs Aotearoa is working to improve the recovery rate.

In an average year, perhaps four meteorites hit New Zealand. We’re encouraging citizen scientists to build their own meteor camera systems so they can catch these events.

By comparing the meteor against the starry background and triangulating images caught by multiple cameras, we can pin down the meteor’s position in the atmosphere to within tens of metres.

Not only does that help us find the rock, but it tells us what the pre-impact orbit of the meteoroid was, which in turn tells us which part of the solar system it came from. This is a rather efficient way of sampling the solar system without ever having to launch a space mission.

Fireballs Aotearoa is rapidly populating Otago with meteor cameras and there are half a dozen more in other parts of the South Island. The North Island isn’t well covered yet, and we’re keen for more people (in either island) to build or buy a meteor camera and keep it pointed at the sky.

Then next time a bright meteor explodes with a boom above New Zealand, we may be able to pick up the meteorite and do some good science with it.

Many thanks for the input from Jim Rowe of the UK Fireball Alliance, and Greg Price who photographed the July 22 meteor and the persistent train.

Australia faces many global and regional challenges – the human and economic toll of the pandemic, the rippling effects of the Russian invasion of Ukraine, troubled relations with Pacific Island countries. But the most consequential of all is US–China rivalry. With the not-so-peaceful rise of China and the waning of American supremacy, Australia has been walking a tightrope, and for the past couple of years the balancing act has not been entirely successful.

The change of government is a good time to discuss Australia’s top foreign policy priorities and how to deal with them. Revisiting the “middle power” concept – what it means and how it works – can help clarify how Australia can better handle these challenging times.

Australia as a middle power

Although not everyone agrees about what defines a middle power, Australia is consistently considered to be among them, as measured by material capabilities, international behaviour and/or self-identity. Even if we define middle powers according to the outcomes rather than the intent of their actions, Australia has been a typical, if not quintessential, middle power. The Lowy Institute Asian Power Index confirms that much.

The most frequently named middle powers have shown a strong commitment to seeking multilateral and cooperative solutions to global and regional issues (with emerging middle powers more focused on their regions).

This is a rational choice, not least because these nations have neither the sheer material power nor the “soft power” afforded to great powers.

Multilateral diplomacy works well for middle powers. Separately, they are vulnerable to great power rivalry; together, they can have a more significant impact on the international system.

Strategic ambiguity (as opposed to blind loyalty to certain powers or groupings) also works well for middle powers. Taking sides can increase the risk for smaller states in a conflict between great powers. China has certainly noticed what it calls a “cold war mentality” in relation to Australia’s increasingly close ties to the US.

What went wrong

No matter what is defined as “the national interest” by the government of the day, Australia has two enduring interests: a security interest aligned with the west and an economic interest increasingly aligned with the east.

The defence alliance with the US is vital to Australia’s national security. But China continues to be Australia’s largest trade partner, with Asia accounting for 65% of Australian’s two-way trade in 2021.

This is why, despite all its political and security concerns, Australia has traditionally sought to maintain a balance between its strong economic relationship with China and its defence alliance with the US. In return, China expressed its appreciation at times when Australia acted independently of the United States. The policy of strategic ambiguity appears to have worked in Australia’s favour when it came to Taiwan and other issues extremely sensitive to China.

But Australia–China ties have hit a rough patch recently. The starting point was China’s provocative activities in the South China Sea and the global impact of its Belt and Road Initiative. That friction was compounded by Australia’s eager embrace of the United States’ vision for the Indo-Pacific.

China has doubled down on its economic and diplomatic coercion since at least 2017. More recently, in response to the Morrison government’s call for an independent investigation into the origin of COVID-19, it has imposed sanctions on many Australian exports.

In response, Australia further cemented its alliance with the US. It helped revive the Quad grouping with India, Japan and the US in 2017, and joined AUKUS, the Australia–UK–US enhanced strategic partnership, in 2021.

The problems multiply

While the economic impact of China’s sanctions has been mild in the short term, there is no telling the future. The disruption of global supply chains due to COVID-19 and now the Russian invasion of Ukraine highlights China’s dominant role in business-to-business trade.

Not only has the prolonged war in Ukraine caused a worldwide cost-of-living crisis, but it also showcases the vulnerability of smaller states and the further decline of the US-led world order. Putting all eggs in one basket may not be a wise choice for Australia.

Besides the China problem, Australian relations with Pacific Island countries have seen better days. Among the reasons for the deterioration are Australia’s reluctance to join forces to mitigate climate change, and its transactional approach to bilateral relations with neighbours.

Australia’s growing defence reliance on the US also polarises key partners in Southeast Asia. Regional powers like Vietnam and Indonesia are vying for multilateralism and cautious about antagonising China. Probably not helpful was the previous government’s scepticism about international organisations together with a longer-term decline in resources for engagement, evidenced by the fact that funding for the Department of Foreign Affairs and Trade has declined over the past three decades.

The way forward

To deal with these challenges, Australia needs a (re-)balancing act based on bilateral and multilateral diplomacy involving a wider pool of key stakeholders in the Indo-Pacific.

Less provocative rhetoric and efforts to identify mutual interests can help de-escalate the tension with China. Diplomacy should be brought back into the forefront, as the new government has sought to do.

Of course, a complete reset of China–Australia ties is unlikely given deep-seated human rights and national security concerns. But the American alliance doesn’t have to come at the cost of derailing trade relations with China. To reduce trade dependence on China, meanwhile, Australia should strengthen relations with India, ASEAN and other trading partners.

To that end, Australia must show Asia and the Pacific that it is a responsible and reliable partner, a “good international citizen”. Expanding development aid, education programs, cultural exchanges and other public diplomacy initiatives can help a great deal. “Climate change” is a common concern among these partners, and should be at the centre of the discussion.

Diplomacy is a long game. It is harder to mend relationships than to break them. It may take a while for Australia to see how diplomacy can help, but middle power diplomacy definitely serves Australia’s national interest.

Alzheimer’s disease is the most prevalent form of dementia and, with a rapidly ageing global population, it is fuelling unprecedented demand for costly patient care. There have been an estimated 400 clinical studies since the first Alzheimer’s drug trial in 1987.

The demand for treatment solutions however, is not without significant risk. There have been recent allegations that research underpinning widely held understandings of what causes Alzheimer’s may be fraudulent. The impact of this on clinical trials is a potentially huge blow for people living with Alzheimer’s and their carers.

In this case, it might be a stretch to say all Alzheimer’s research is now compromised. But the allegations can prompt us to interrogate whether the governing bodies of research and drug approvals are truly effective.

A potentially flawed hypothesis

The concerns of possible Alzheimer’s research fraud follow findings by neurologist and physician Matthew Schrag, detailed in the journal Science.

Schrag wrote that an ongoing Alzheimer’s trial investigating the experimental drug simufilam was based on manipulated images published by scientists years earlier. If true, then volunteer patients to drug trials, including the simufilam studies, may be facing unnecessary health risks associated with experimental treatment – likely with no hope of clinical benefit.

Moreover, years of drug development costing tens of millions of dollars might have been wasted. The fundamental premise of what causes brain cell death in Alzheimer’s and by extension, what type of drugs are needed to be developed for treatment, may now need reconsideration.

Some contemporary Alzheimer’s clinical trials are based on a now potentially flawed hypothesis: that brain cell death is triggered by the early formation in the fluid that bathes the brain, of small clumps of protein called amyloid-oligomers.

One highly influential and highly cited study is at the centre of the current controversy. The authors claimed mouse models of Alzheimer’s showed memory impairment was associated with the accumulation of amyloid-oligomers. Schrag found compelling evidence the image presented in the 2006 paper may have been modified.

What causes Alzheimer’s disease? What we know, don’t know and suspect

What about peer review though?

The internationally adopted peer review system, where discipline experts anonymously review scientific data put forward for publication, usually ensures robust outcomes. This should reassure the public about a study’s scientific claims. However, as the saying goes, science doesn’t lie, but people may.

In this instance, Schrag reviewed scores of images in scientific papers authored by neuroscientist Sylvain Lesné and suggested significant image tampering had consistently occurred. Leading independent image analysts and internationally recognised Alzheimer’s researchers backed Schrag’s claims.

Neuroscientists can rightfully be exceedingly disappointed publications that changed what we know about Alzheimer’s or other diseases now appear based on manipulated data. It potentially brings neuroscientists into disrepute and undermines public confidence.

The allegations have brought trials for two drugs with simfilam under serious scrutiny.

It’s important to stress simufilam has not been approved by any regulatory agency. But a recent United States Food and Drug Administration (FDA) approval of the drug aducanumab – against expert advice which warned there wasn’t enough evidence to show it worked – has made physicians treating people living with Alzheimer’s extra sensitive.

Other avenues of research

So does news of this potential fraud mean the field of Alzheimer’s research is corrupted? Can we be confident that what is prescribed to patients is safe and works?

We should keep in mind the broader context that publishing incorrect data is rare and research misconduct is even rarer. If incorrect data is identified, restorative practices are usually swift and comprehensive, including publishing “errata” corrections, or possibly, a retraction of findings by scientific journals. Significant penalties are also imposed for deliberate research misconduct.

Also, there are multiple clinical trials considering multiple aspects of the complex Alzheimer’s cascade from what causes the disease to how it affects memory and thinking. These are based on credible scientific findings.

Amyloid-oligomer clearance, which is now being questioned, is only one avenue that scientists have pursued.

The overwhelming majority of scientists are doing the right thing all of the time and if regulatory approval authorities such as our Therapeutic Goods Administration and the FDA continue to sensibly and thoroughly examine the evidence provided for approval, then we can hope for a better future for people living with Alzheimer’s.

When the new federal parliament opened last week, a record number of female politicians took their seats: 38% in the House of Representatives and 57% in the Senate. This changing of the guard, with women at the forefront, brings an opportunity to accelerate Australia’s efforts on climate change.

The major parties were virtually silent on the issues of gender equity and climate change throughout the 2022 election campaign. Yet, both issues proved to be turning points for the Australian electorate.

Climate change – one of the key platforms on which the teal candidates successfully campaigned – is central to Prime Minister Anthony Albanese’s parliamentary agenda. A bill to enshrine a climate target into Australian law was among the first introduced to parliament last week.

Women are on the front line of climate change impacts, which makes our experiences and leadership critical at decision-making tables. From Barbados to Finland, we’ve seen women’s leadership on climate bring fair, innovative and ambitious policies. We hope a new era in Australian climate policy is upon us, too.

Women and climate change

Women around the world are disproportionately impacted by climate change due to existing systemic inequalities. For example in Africa, when disaster strikes, women may find it more difficult to evacuate their homes as primary caregivers, be unable to read written warnings, or be overlooked in rescue attempts in favour of men.

Australia’s experience is no exception. For example, researchers note sharp surges in domestic violence in the wake of disasters, such as bushfires.

Women also have a critical role to play in achieving ambitious and innovative climate action. As the Women’s Leadership statement at last year’s Glasgow climate summit noted:

Despite increased vulnerability to climate impacts, we recognise that women and girls have been creating and leading innovative climate solutions at all levels.

There are scores of examples of female climate leadership and the benefits that follow when women and girls are afforded the opportunity to take a lead on climate action, throughout recent history.

Notable examples include Christiana Figueres, who steered international climate negotiations to a successful outcome in 2015, with the adoption of the Paris Agreement.

Greta Thunberg’s vigil to sit outside the Swedish Parliament every Friday protesting inadequate climate action inspired a youth climate protest movement.

Other young women such as National Director of Seed Mob Amelia Telford in Australia, and Pacific Climate Warriors founding member Brianna Fruean are at the forefront of First Nations’ climate advocacy efforts.

An OECD Working Paper released this year notes that women’s participation in decision-making often leads to the development of comparatively strong and sustainable climate policies and goals.

Case in point, Finland, under leadership of progressive Prime Minister Sanna Marin, recently committed to one of the most ambitious climate targets, legislating net zero by 2035 and carbon negative by 2040.

Meanwhile, Barbados Prime Minister Mia Mottley aims to phase out fossil fuels by 2030 and is a passionate advocate for developing nations vulnerable to climate change.

In the private sector, women’s participation is also crucial. The OECD cites evidence that when women occupy at least 30% of board seats they bring about change to climate governance within companies.

An end to Australia’s climate wars?

The Australian government’s sharp focus on climate change is a far cry from the “climate wars” that have been a roadblock to meaningful climate policy in this country for the past decade.

But Australia wasn’t always a problem country in international climate negotiations. At times, we’ve been a climate leader.

Climate wars, carbon taxes and toppled leaders: the 30-year history of Australia’s climate response, in brief

Under Julia Gillard’s Labor government, for example, Australia was one of the first countries to introduce a national legislated carbon price in 2011. This changed in 2013, when the newly elected Prime Minister Tony Abbott swiftly repealed this landmark law. Almost a decade of inaction on climate change by the federal government followed.

Signs of progress on climate change began to take shape at the 2019 federal election, when conservative but green Independent MP Zali Steggall ousted Tony Abbott from his long-held seat of Warringah.

The May election then brought a teal wave of female independents, along with gains for Greens and Labor women candidates. These women – such as Kate Chaney, Zoe Daniels, Monique Ryan, Sophie Scamps, Kylea Tink, Zali Steggall and Allegra Spender – are set to play a transformative role in our politics and society.

They campaigned on a climate and integrity platform, calling for stronger 2030 climate targets, increased renewable energy generation and passing a Climate Change Act to legislate and lock in emissions reduction targets.

Labor’s Climate Change Bill was one of the first pieces of legislation to be introduced to the new parliament, and negotiations are now well underway between Labor, the Greens and the female independents to pass it.

À lire aussi :
There’s a smart way to push Labor harder on emissions cuts – without reigniting the climate wars

An early success borne from these negotiations has been establishing that Labor’s current target – 43% emissions reduction by 2030 – is a floor, not a ceiling, for ambition.

Still, as Kate Chaney put it in her first speech, “we need to go further”. This includes addressing questions about accountability for achieving the target, and a mechanism to ensure future governments continue to lift their ambition.

Towards a positive climate future

The success of the teal independents represents the enormous groundswell of anger and frustration felt by many people who might have, in the past, voted for the Coalition government.

This immense transformation points to the need for Australia to place gender equity, climate action and integrity at the centre of our decision-making.

As our national climate laws and policies take shape, we watch with anticipation to see how Albanese will navigate two houses occupied by women with strong, clear climate objectives and unprecedented support from their electorates.

One of Australia’s most prestigious boys’ schools has just announced it will go co-ed.

Last week, Sydney’s Cranbrook School – whose alumni include Kerry and James Packer and Atlassian founder Mike Cannon-Brookes – announced it will be fully co-educational by 2029.

Cranbrook joins a growing list of private schools around the country that are either considering going co-ed or have already done so. These include Newington and Barker College in Sydney, The Armidale School in NSW and Canberra Grammar in the ACT.

Does this mean we are seeing the beginning of the end of all-boys’ schools?

Single sex vs co-ed

Single sex vs co-ed debates have been going for decades in education circles. Which creates better outcomes? Is the answer different for boys than for girls?

It’s also one that many parents have a strong personal view on, perhaps influenced by what they experienced growing up.

À lire aussi :
Single-sex vs coeducational schools: how parents can decide the best option for their child

The short answer is, decades of research into the topic remains inconclusive.

When it comes to students’ academic achievement, the biggest predictor of success is not gender but socio-economic status, whether they live in a rural or remote area, and race (especially if they are Indigenous).

The gender question

When it comes to social outcomes, the debate becomes more complicated.

Some research has criticised single-sex schools for segregating girls and boys, exaggerating differences between them and putting them in opposition to each other. This is not helpful when preparing students for understanding gender diversity and negotiating the world beyond school.

But research has also shown how boys take up much more physical space and teacher time in schools and classrooms than girls. Boys tend to be more disruptive, and require more discipline and attention.

Some research indicates boys may do better in co-ed environments than girls. Education researchers have long-acknowledged that girls can be a positive influence on boys’ behaviours – but to the detriment of their own learning. For example, girls may be asked to sit next to disruptive boys as a calming influence.

This, of course, reproduces inaccurate and tired gender stereotypes of girls as passive and diligent and boys as boisterous and unruly.

What did #MeToo do?

A critical recent shift has also been the #MeToo movement. In the education context, in 2020, former Sydney private school student Chanel Contos started a petition asking for students to share their stories of sexual assault.

In response to Contos’ petition, Cranbrook’s head prefect at the time, Asher Learmonth made a speech, noting, “Our school features heavily […] too heavily […] once again.” Cranbrook was among the schools Contos wanted to see introduce consent education.

The reckoning about gender relations in general and the school petition in particular, has focused much-needed attention on the sexism, misogyny and abuse that can breed in hyper-masculine environments.

All-boys’ schools also tend to be private schools – and this privileged environment can amplify a sense of entitlement. The point is, all or mostly male environments (whether they be in sport, business or politics) are not good for gender equality.

A social shift

What we are seeing here is not a shift in educational theory, but a shift in society’s expectations. As Cranbrook school leaders explained their decision to go co-ed:

Many see the transition as being a necessary and inevitable step forward in the context of a modern society.

But when we’re talking about the shift to co-ed, don’t forget that private schools are also businesses and they have to attract students.

Parents may be more attracted to co-educational private schools given the recent stories about the culture at some all-boys’ schools thanks to the schools’ petition and other high-profile reports of sexist behaviour. Going co-ed is not just a way to foster a “modern” environment at school, it makes good business sense as well.

Including girls in all-boys’ schools might seem a good solution to the problem and prevalence of sexism. However this is not an easy fix. Unhealthy attitudes about gender are rife in all schools as they are in the broader social world.

So, all schools need to be supported to create safe, respectful learning and social environments, with adequate training and teaching resources.

Review: D Harding with Kate Harding Through a Lens of Visitation, Chau Chak Wing Museum

Entering D and Kate Harding’s Through a Lens of Visitation, Kate’s textile work Cylinders (2020) was the first thing to draw my attention. Higher than the surrounding works, it draws the eye with its bold geometric patterning in greens and ochre contrasting with the more organic palette of the surrounding work.

D Harding is a star of contemporary Australian art with a flourishing international profile. Their mother, Kate, is a textile artist who in recent years has used quilts to tell stories of family and country.

This exhibition shows the connections between a mother and child and the culture that forged them, foregrounding the contribution of Indigenous women.

D and Kate Harding are descendants of the Bidjara, Ghungalu and Garingbal peoples, and have strong continuous connections to the internationally significant heritage site of Carnarvon Gorge in central Queensland.

Attracting tourists for its natural and cultural values, the gorge is known for its exceptional rock art. However, the tourist lens has often obscured the spiritual importance for First Nations people. This exhibition and accompanying publication corrects this lens by foregrounding the living culture of First Nations people from a number of different viewpoints.

Threading together the artists’ Indigenous culture with rigorous scholarship, this exhibition challenges Australian art history.

An undulating landscape

The exhibition is predominately of textile works by both artists, accompanied by two of D’s large-scale paintings.

Throughout the exhibition, object and textile works are placed on tightly assembled plinths of various heights.

Plinths are the common white supports used to ensure sculptural works and statues can be examined closely. Most viewers do not even notice them. But in D’s work, the line dividing the plinth from the work is blurred.

As you enter, the lowest plinth is closest to the entrance, and the highest – standing at two metres tall – is in the back corner furthest from the entry. This creates an undulating landscape for the audience as they enter the gallery, and we feel an invitation to explore.

D told the audience at the opening the plinths signalled “hierarchies of care”. They adopted this gallery convention to present Indigenous culture with the same care reserved for classical treasures. Interventions like this counter the way museums have historically portrayed First Nations culture as anonymous ethnographic curiosities.

Attention to the object

In the middle of the field of plinths are two wrapped objects which remain secret, packaged neatly as if by a conservator preparing for safe storage.

The wall text reveals what audiences cannot see: two of D’s 2018 works Untitled Cloak and Repression cloak (ceremony for a gay wedding). Occupying the remainder of the plinths in the Penelope gallery are six textile works, visible but neatly folded to obscure a clear view.

The wrapped objects recall Christo and Jeanne-Claude, drawing attention to the object, asking audiences to look at the overlooked. D’s wrapping safeguards Indigenous knowledge not for general consumption and ensures cultural safety.

This is most explicit in a redacted reproduction of a photograph of Carnarvon Gorge: what is withheld from view may be as significant as what is on display.

In remembering Christo, we remember what art once was

The exhibition encourages thoughtful inquiry. Each of the works on display was developed through years of sustained practice with deep respect for their materials, knowledge of place, Songlines and Indigenous cultural practices.

In Kate’s textile work this inquiry is achieved through a range of quilts which employ natural dyes including the bold angular geometry of Carnarvon (2020) to the more organic forms which dominate White Hill – looking for food at Clermont (2020). Her works are stylistically diverse, each conveying different story lines.

In this exhibition, D’s acclaimed painting practice is accompanied with textile work, making the two artists’ work often indistinguishable. This is most visible in Emetic painting (International Rock Art Red and White) (2020), whose forms and colours resonate with those found in Kate’s quilts.

The potential of materials to convey historical stories is clear in Blue ground/dissociative (2017), which uses white ochre on an arresting ground of Reckitt’s Blue pointing to the diverse traditions informing this exhibition.

The individual works, their careful display in this exhibition and the publication demonstrate a profound respect for both the language of contemporary art and Indigenous traditions.

It is a significant achievement.

Predictions of catastrophic climate change seem endless – and already, its effects are hard to ignore. Events such as bushfires, floods and species loss generate feelings of sadness, anxiety and grief in many people. But this toll on the human psyche is often overlooked.

Our research has investigated the negative emotions that emerge in Australians
in response to the destruction of nature, and how we can process them. We’ve found being in nature is crucial.

Our latest research examined an eco-tourism enterprise in Australia. There, visitors’ emotional states were often connected to nature’s cycles of decay and regeneration. As nature renews, so does human hope.

As our climate changes, humans will inhabit and know the world differently. Our findings suggest nature is both the trigger for, and answer to, the grief that will increasingly be with us.

Emotions of climate distress

Our research has previously examined how acknowledging and processing emotions can help humans heal in a time of significant planetary change. This healing can often come about through social, collective approaches involving connection with the Earth’s natural systems.

Eco-tourism experiences offer opportunities to connect with nature. Our recent research examined the experiences of tourists who had recently stayed at Mount Barney Lodge in Queensland’s Scenic Rim region.

The eco-tourism business is located on Minjelha Dhagun Country, next to the World Heritage-listed Mount Barney National Park. The region was badly affected by the Black Summer bushfires of 2019-2020.

Through an online questionnaire conducted last year, we sought to understand visitors’ psychological experiences and responses while at the lodge.

Seventy-two participants were recruited via an information sheet and flyer placed in the lodge reception. The youngest was aged 18, the oldest was 78 and the average age was 46. Some 71% were female and 29% were male.

We found 78% of respondents experienced sadness, anger, anxiety and other grieving emotions in response to current pressures on the Earth’s life supporting systems.

One reflected on how they “have laid awake at night thinking about all the biodiversity loss [and] climate change and wept” and another said they felt “so sad for the animals” in the face of bushfires or urban sprawl.

This is Australia’s most important report on the environment’s deteriorating health. We present its grim findings

Another participant spoke of their sadness following bushfires in the Snowy Mountains fires of New South Wales:

This area is where I [spent] much of my youth, so it was really sad to see it perish. I felt like I was experiencing the same hurt that the environment (trees, wildlife) was – as my memories were embedded in that location.

This response reflects how nature can give people a sense of place and identity – and how damage to that environment can erode their wellbeing.

But grief can also emerge in anticipation of a loss that has not yet occurred. One visitor told us:

When I was little, I thought of the world as kind of guaranteed – it would always be there – and having that certainty taken away […] knowing that the world might not be survivable for a lot of people by the time I’m a grown-up – it’s grief, and anger, and fear of how much grief is still to come.

Anger and frustration towards the then-federal government were also prominent. Participants spoke of a “lack of leadership” and the “government’s inability to commit to a decent climate policy”. They also expressed frustration at “business profits being put ahead of environmental protection”.

Participants also said “it feels like we can’t do anything to stop [climate change]” and “anything we do try, and change is never going to be enough”.

Healing through immersion in nature

Emotions such as ecological grief and eco-anxiety are perfectly rational responses to environmental change. But we must engage with and process them if their transformative potential is to be realised.

There is increasing evidence of nature’s ability to help people sit with and process complex emotional states – improving their mood, and becoming happier and more satisfied with life.

Participants in our study described how being in natural areas such as Mount Barney helped them deal with heavy emotions triggered by nature’s demise.

Participants were variously “retreating to nature as much as possible”, “appreciating the bush more” and “spending as much time outside [so] that I can hear trees, plants, and animals”.

6 books about the climate crisis that offer hope

Participants explained how “being in nature is important to mental wellbeing”, is “healing and rejuvenating” and “always gives me a sense of spiritual coherence and connection with the natural world”.

For some, this rejuvenation is what’s needed to continue fighting. One participant said:

If we don’t see the places, we forget what we’re fighting for, and we’re more likely to get burned out trying to protect the world.

Similarly, one participant spoke of observing the resilience and healing of nature itself after devastation:

[I] find peace and some confidence in its [nature’s] ability to regenerate if given a chance.

The call back to nature

Our findings suggest immersing ourselves in nature more frequently will help us process emotions linked to ecological and climate breakdown – and thus find hope.

Eco-tourism sites promote opportunities for what’s known as eutierria – a powerful state that arises when one experiences a sense of oneness and symbiosis with Earth and her life-supporting systems.

Through this powerful state, it’s possible for one to undertake the courageous acts needed to advocate on behalf of nature. This is essential for the transformations Earth desperately needs.

Australia’s wildlife is increasingly threatened with extinction. One key driver of this is habitat clearing and fragmentation. An associated factor is the expansion of our road network, particularly the upgrade and duplication of our highways.

Governments expand our major highways in the interests of road safety and traffic flow. But major roads become barriers to wildlife movement, as well as places where cars can hit and kill many animals.

Our new research explores whether highway underpasses help animals safely cross roads. We wanted to know if animals actually use underpasses – and if they had hidden dangers by funnelling animals through a confined space, making it easier for predators.

What did we find?

To find out whether underpasses work, we used wildlife cameras to monitor 12 underpasses for more than two years in north-east New South Wales. Five under the Oxley Highway at Port Macquarie and seven under the Pacific Highway south of Grafton.

What we found was quite astounding. Vastly more animals than we expected were using the underpass. We detected over 4,800 medium-large mammals and goannas, while smaller species such as snakes and rodents also used the underpasses but were less reliably detected by our cameras.

Species such as eastern grey kangaroos, swamp wallabies, red-necked wallabies, red-necked pademelons and lace monitors crossed some underpasses more than once a week. Rufous bettongs and echidnas crossed individual underpasses every two to four weeks. These crossing rates suggest animals use underpasses to forage on both sides of the freeways.

We were particularly interested in whether the endangered koala would use the underpasses. They did, occasionally. We found they were not avoiding the underpasses, because they were detected infrequently in the adjoining forest.

Do underpasses with fences reduce or eliminate wildlife roadkill? Anecdotal evidence for our study road at Port Macquarie suggested roadkill rates were very low. Only four roadkills (two eastern grey kangaroos, one red-necked wallaby and one brushtail possum) were reported to the local animal welfare group for this road segment over a three year period encompassing our study. However, we should not be complacent. Roadside fences develop holes and need to be repaired to maintain their value.

Do underpasses attract predators?

Many people believe underpasses increase predator risk. This idea – known as the “prey-trap hypothesis” – suggests predators will be drawn to places where they can easily pick off unsuspecting animals funnelled into the confined space of an underpass.

We detected red foxes, feral cats and dingoes using these underpasses. But of these, only foxes were detected frequently enough to be a potential concern.

We tested the prey-trap hypothesis by testing three predictions. If the hypothesis was correct, foxes should be more common in the underpasses than in the forest, foxes should focus their activity at underpasses where potential prey are more abundant and the timing of use of underpasses by foxes and potential prey should coincide.

What we observed didn’t match these predictions. At Port Macquarie, foxes were detected at three underpasses, while being absent from two. Of the three underpasses used by foxes, one particularly favoured by foxes was not favoured by bandicoots and pademelons, the potential prey.

Safe passage: we can help save koalas through urban design

We expected to detect foxes close in time to prey detection. But on average, there was a gap of over three hours between detecting foxes and bandicoots or pademelons, and over four hours between foxes and wallabies. We also found foxes were less often detected on nights when potential prey were using the underpasses.

These observations suggest potential prey may be avoiding the underpasses when foxes are about.

What conclusions can we draw?

Underpasses are a useful tool to enable wildlife to move across landscapes with roads. Not all ground-dwelling species of wildlife will find underpasses to their liking, but many do.

Could we retrofit underpasses to highways with very high roadkill rates? That depends. The conditions have to be right. For an underpass to be installed, you need the road to be adequately elevated. You also need roadside fences, to prevent animals taking the shorter but much more dangerous path across the highway. These fences don’t work if there are intersections, freeway off ramps or driveways.

What we need is to prioritise areas where underpasses are possible, where threatened species exist and roadkill rates are high. It’s very expensive to retrofit underpasses into existing roads, which is why we have to focus on priority areas.

In the future, it could be possible to use cattle-grid type structures to stop animals like koalas getting around fences and onto the roads. These are currently being trialled.

To figure out how to make underpasses even more effective, we need more publicly available research. At present, there’s a great deal of monitoring sitting in expensive but unpublished reports from consultants.

Underpasses are not a panacea for impacts on wildlife. And we shouldn’t use their effectiveness as a justification to run highways through pristine areas. They’re a tool to minimise impacts of road projects that have wide community support.

We’ve now seen the first data from the James Webb Space Telescope. It has observed the atmospheres of distant planets, groups of nearby galaxies, galaxy light bent by unseen dark matter, and clouds of gas and dust in stellar nurseries.

We have also seen headlines claiming Webb has found “the oldest galaxies we have ever seen”, but what does that mean?

I’m a professional astronomer who studies old galaxies, and even I find this a little puzzling.

Looking far, looking back

One of the key science goals of Webb is to peer back in time and observe the early Universe. Webb can do this because, like all telescopes, it is a time machine.

Light travels at 300,000 kilometres per second, so when we look at the Moon we are seeing it as it was a second ago. As the planets of our Solar System are millions or billions of kilometres away, we see them as they were minutes or hours ago.

Going further still, when we look at distant galaxies with telescopes we are often looking at light that has taken millions or billions of years to reach us. This means we are seeing these galaxies as they were millions or billions of years ago.

Read more:
When you look up, how far back in time do you see?

What has James Webb seen?

The James Webb Space Telescope is able to see more distant galaxies than other telescopes, including the Hubble Space Telescope.

Like Hubble it is above the glowing and turbulent atmosphere of the Earth. However, whereas Hubble has a 2.3 metre mirror for focusing light, Webb has a vast 6.5 metre mirror formed from 18 hexagonal segments. Finally, Webb is optimised to detect infrared light, which is what we observe from the most distant galaxies as the expansion of the Universe has stretched ultraviolet and infrared light into the infrared.

Among the first data obtained by Webb were infrared images looking towards a cluster of galaxies called SMACS 0723.

The light from SMACS 0723 has taken 4.6 billion years to reach us, so we are seeing it as it was 4.6 billion years ago. That’s slightly older than the Sun and the Earth, which only formed 4.56 billion years ago.

In recent weeks, galaxies far beyond SMACS 0723 have gained attention. Webb has detected a number of galaxies in the direction of SMACS 0723 and other regions that could be so distant their light has taken 13.5 billion years to reach us.

I say “could” because more data will be needed to absolutely confirm their distances, but some of these galaxies are very compelling candidates (others less so).

As the light has taken 13.5 billion years to reach us, we are seeing these galaxies as they were 13.5 billion years ago. The Universe itself is 13.8 billion years old, so we could be seeing galaxies as they were just a few hundred million years after the Big Bang.

Young, old or early?

While these very distant galaxies have been advertised as the “oldest galaxies”, I find this a little confusing. We are actually seeing these galaxies as they appeared when they were very young, perhaps a hundred million years old or so.

It is true that these galaxies will be old now, but our own Milky Way galaxy is very old now too. While our Sun is 4.56 billion years old, many stars in our galaxy are 10 billion years old and some stars in the Milky Way are 13 billion years old.

Furthermore, the very distant galaxies Webb has spotted will look very different today. Galaxies grow by acquiring gas and dark matter, forming new stars and merging with other galaxies.

A small galaxy that was vigorously forming stars soon after the Big Bang may have ended up being the seed of a galaxy that today is very massive and stopped forming stars long ago. That small galaxy and its old stars could also have ended up being just part of a larger galaxy formed relatively recently by merging galaxies together.

A record set to fall

So should we call these most distant galaxies young or old? Perhaps neither.

James Webb is seeing the earliest galaxies yet observed – some of the first galaxies that formed soon after the Big Bang.

I have thrown in one last caveat – “yet observed”. Webb has only just begun its mission, and current analyses are based on data collected over hours.

With days’ worth of data, Webb will push its view out to fainter and further objects, and see yet-more-distant galaxies. The record for the most distant and thus earliest observed galaxy will probably tumble a few times before the year is out.

Bang! A child trips and grazes their knee. Your toddler bumps his head on the table. Your niece stubs her toe. The tears flood in.

Do you: (a) tell them to “brush-it-off”, (b) make a fuss and laboriously check for grazes, or (c) give them a cuddle, quick check, and encourage them to keep playing?

I am a physiotherapist and clinical pain neuroscientist from the University of South Australia. Recently, my colleagues and I published research investigating strategies to promote recovery and resilience in young children after injury.

While a parent or caregiver’s response to a child’s bumps or scrapes will depend on the child, the situation and the injury, generally, my research suggests a response like option c: comfort and reassurance (a cuddle), first-aid scan (quick check for grazes), and encourage them to manage their pain using distraction (return to activity).

Learning how to respond to pain

Everyday pain and injuries – such as minor bumps, cuts, grazes – are critical learning experiences for young children, and can influence how they interpret and respond to pain or injury experiences in the future.

This is important because one in five adolescents and adults will experience persistent or chronic pain problems, such as back pain, headaches or abdominal pain.

Read more:
Parents’ reactions can lessen or worsen pain for injured kids

We don’t (yet) know how to prevent children from developing persistent pain problems. But teaching people with persistent pain about how pain works helps reduce their pain.

We all learn about pain and injury through our own life experiences. When we get an injury, pain follows. Therefore pain must mean injury, right?

Actually, it’s not that simple. One of the difficulties health practitioners face in teaching people about pain is that they are often challenging long-held beliefs about how pain and recovery works.

Instead of trying to challenge these life-long developed beliefs, we can work “bottom-up” and start educating children about pain and injury from early on.

Investigating helpful pain behaviours

With a vested interest in this myself (I have two young children), my colleagues and I wanted to find out what parents and caregivers can do to teach children about pain that might promote “helpful” pain behaviours. That is, behaviours that are likely to lead to recovery, and build resilience for the future (and hopefully prevent future pain problems).

To address this, we investigated “everyday” pains – mostly because they are common in young children, but also because experience through learning can be very powerful.

So, we conducted a study asking eighteen international experts from child health, psychology, development, resilience, as well as parents and educators, what parents and caregivers could do to promote recovery and resilience after minor pains and or injury.

While recognising that all children and experiences will be unique, here are five key tips from the experts:

1. Teach children about the meaning of pain

Teach children that pain is our body’s alarm system: it’s there to protect us from danger.

It’s also important to note that pain and injury don’t always align. How we’re feeling on the inside, for instance, can influence how much pain we are in. If children are hungry or tired, the pain might seem worse.

2. Validate children’s pain and injury

This could involve getting down to the child’s level, acknowledging their pain and or injury, and how they’re feeling.

Ensure children feel safe, heard, and protected.

But don’t make a big fuss of it. Every child and event will be different, so use your judgement to strike a balance.

3. Reassure them

Let them know that their body is amazing and will heal and recover; and the pain will pass.

4. Support children’s emotional development

Role-model empathy, allow children to express their emotions, and encourage them to connect to their body’s warning signs.

This might include helping them talk about or show their feelings. Be mindful to not let your own reactions and emotions intervene. A fearful and shocked reaction to an injury may instil fear in that child.

This doesn’t mean letting the child wail and carry on. Rather, let them express themselves and then encourage them to regulate their emotions. This could involve encouraging deep breathing and connect to what it is they are feeling on the inside.

5. Involve children in managing their own pain and injury

Encourage children to make decisions and attend to their pain and injury, in an age-appropriate way. This might involve getting a band-aid, wet cloth, rubbing the area, or distraction.

Discuss first-aid and healing processes. Pop on a band-aid, tell them their “ouchie” is protected, and that it’s safe to move and play.

Be mindful of your language – demonstrate that they are the healers, rather than “getting fixed”. For example, you could talk about when we eat good food and get lots of good sleep, we are setting up our bodies to have lots of energy to heal and get better. This encourages active involvement in the healing process.

In everyday life, children will be exposed to lessons about pain and injury in many other social, cultural and educational contexts. Pain is commonly shown in children’s movies and TV shows in unhelpful ways, with low levels of empathy and gender stereotypes, where boy characters sustain more injuries than girls, but observers are more responsive to girls.

Therefore, how parents and caregivers communicate with children about pain and injury is important, and can build resilience after injury.

The first Newspoll since the May federal election, conducted July 27-30 from a sample of 1,508, gave Labor a 56-44 lead (52.1-47.9 to Labor at the election). Primary votes were 37% Labor (32.6% at election), 33% Coalition (35.7%), 12% Greens (12.2%), 6% One Nation (5.0%), 2% UAP (4.1%) and 10% for all Others (10.5%).

Prime Minister Anthony Albanese’s satisfaction rating was 61% (up 20 since the final pre-election Newspoll) and his dissatisfaction rating was 26% (down 20). That gave Albanese a net approval of +35, up 40 points.

The Poll Bludger said Albanese’s net approval is the highest for a PM since early in Malcolm Turnbull’s tenure after he toppled Tony Abbott in September 2015. Prior to Turnbull, Kevin Rudd in October 2009 was the last to exceed Albanese’s net approval.

Albanese has a higher “satisfied” rating than any other new PM after a change of government election. But Newspoll has changed its methods since Rudd was PM, resulting in a lower undecided vote on the PM’s ratings. Net approval should be used for comparison with past PMs.

Opposition Leader Peter Dutton’s initial ratings were 41% dissatisfied, 37% satisfied (net -4). In comparing debut ratings for opposition leaders since 2006, The Poll Bludger said Dutton’s net approval was worse than all except Albanese, who had a -5 net approval in his first poll as opposition leader.

Albanese led Dutton by 59-25 as better PM, which The Poll Bludger says is the widest gap since early 2008 under Rudd. Now that we have a Labor PM, this measure will skew towards Albanese. Better PM skews to incumbents, not parties.

These ratings for Albanese are “honeymoon” ratings that are likely to fade as more opposition builds to his agenda. High inflation is likely to damage Albanese and Labor if it persists.

Essential: should the Greens support Labor’s 43% emissions reduction target?

In an Essential poll, conducted in the days before July 26 from a sample of 1,082, 50% thought the Greens should vote for Labor’s policy to reduce greenhouse gas emissions by 43% by 2030, 25% thought the Greens should only vote for Labor’s policy if Labor agrees to changes to bring it closer to Greens policy, and 25% said they did not want further action on climate change.

68% of those who voted Labor at the federal election wanted Labor’s current policy, while just 22% thought Labor should shift towards the Greens’ position. Among Greens voters, 52% thought Labor should shift while 40% did not.

Among the 75% who wanted further climate change action, 44% thought the 43% target is a sufficient contribution from Australia to limit the impact of climate change, while 40% thought more needs to be done.

Voters rated the new Labor government good at handling COVID by 36-27, education by 35-18 and climate change by 33-21. But Labor received a poor rating on cost of living (41-23 poor).

Well over 50% thought the federal government had a lot or a fair amount of influence over various economic issues, implying that voters will blame the government for a poor economy. Labor will hope inflation is under control and the economy is doing better by the 2025 election.

Just eight of 44 constitutional referendums have succeeded

Albanese has proposed a referendum to recognise an Indigenous Voice to Parliament in the Australian Constitution. Our constitution can only be changed by referendum, with a majority of the overall vote and a majority in a majority of the states (so four of the six states).

Just eight of the 44 referendums proposed since federation in 1901 have succeeded. Another five would have succeeded if only a simple popular vote majority had been required, but failed as at least three states were opposed.

The last constitutional referendums were in 1999, when a referendum on becoming a republic failed. The last successful referendums were in 1977, which required the replacement of a casual Senate vacancy with someone from the same party.

Australia has also had four non-constitutional referendums (plebiscites), where the law could have been altered by legislation alone but a public vote was desired. The successful same-sex marriage plebiscite in 2017 was the most recent.

The other three plebiscites were two narrowly defeated conscription plebiscites in the First World War and the plebiscite that chose Advance Australia Fair as our national song in 1977.

The one previous occasion in which a referendum on Indigenous rights was proposed resulted in a record “Yes” vote of over 90% at the 1967 referendum. The same-sex marriage plebiscite had a 61.6% Yes vote nationally, easily winning in every state.

Previous referendums have mostly involved proposals to reform our system of government. It’s likely the high failure rate is because voters take the attitude that if it ain’t broke, don’t fix it. Partisan politics is also a factor, and if the Coalition opposes the Voice, the chance of a successful referendum drops.

Recent extreme weather events have underscored the need to cut the CO₂ emissions that are driving up global temperatures. This requires a rapid transition of the energy economy to renewable energy sources, the cheapest being solar photovoltaics (PV). And our newly published research points to a way we can drive down costs of the shift even further using cheaper forms of silicon for highly efficient solar panels.

Australia has been leading the way with solar PV installations, but our solar energy journey is just beginning. This year, humanity hit a milestone of 1 terawatt (TW) – 1 million × 1 million watts – of installed solar capacity. However, experts predict 70TW of solar PV may be needed by 2050 to power all sectors of the economy.

To help drive this rapid uptake of solar PV, we need solar panels that are high efficiency and low cost. Over the past ten years, some new solar cell designs have led to record high efficiencies. The problem is these designs also need higher-quality materials, which cost more.

Our recent research suggests we might be able to rethink the type of silicon needed to make these high-efficiency solar cells.

Not all silicon is equal

More than 95% of solar panels are made using silicon. The silicon used to make solar cells is similar to that used in computer chips. It’s effectively very pure sand.

To make a solar cell work, we need to form an electric field so the generated current can all flow in one direction. This is done by adding impurity atoms into silicon, a process known as “doping”.

In commercial panel manufacturing, the most commonly used type of silicon is “p-type” silicon. This material is doped with atoms that have one less electron than silicon, such as boron or more recently gallium.

We can then introduce a very thin layer on the surface full of atoms with one extra electron relative to silicon, which is called “n-type” silicon. Placing these two types of silicon together forms what is called a “p-n junction”. The massive difference in the number of electrons between the p-type region and n-type region forces electrons to move rapidly, creating an electric field that drives the current in our solar cell.

Conventional solar panels on Australian roofs today are overwhelmingly made using p-type silicon, as it is about 10% cheaper than the alternative “n-type” silicon, doped with phosphorus.

Higher efficiency comes at a cost

Researchers are continually pushing to drive up the efficiency of solar panels so they can generate more power for consumers. In 2017, a record efficiency of 26.7% was achieved for a silicon solar cell. Last month, LONGi Solar announced an efficiency of 26.5% – very close to the world record – for the same type of solar cell made in a manufacturing environment, rather than in a laboratory.

This type of solar cell is called a “silicon heterojunction”. The special element of silicon heterojunction solar cells is that the surface is capped with a very thin layer – about 1,000 times thinner than a human hair – of amorphous silicon. This thin layer smooths the surface and reduces a lot of the energy losses.

Sanyo developed this cell design in the 1990s. At the time, high-quality n-type silicon wafers were used to make silicon heterojunction cells, even though these wafers are more expensive.

The main reason for this is that sunlight degrades cheaper p-type wafers. However, our understanding of this phenomenon and how to treat it has come a long way since the 1990s.

Our light-bulb moment

For the past 30 years, all silicon heterojunction solar cells, including the record-breaking cells, have been made using n-type silicon wafers. In our research project, we wanted to test whether cheaper, p-type wafers could also be used.

Through comprehensive testing, we found heterojunction solar cells made with p-type silicon did not perform as well. We were puzzled by this. But one day we had a literal light-bulb moment.

We realised that accidental exposure to room lighting for as little as ten seconds before testing reduced the voltage of p-type cells by as much as 30mV, which can cut their efficiency by a percentage point (i.e. from 22% to 21%). This was causing our cells to perform much worse than expected. Much like someone who has severe allergies is more sensitive to pollen in the spring, we realised these high-efficiency silicon heterojunction solar cells made with p-type wafers are much more sensitive to light-induced degradation.

Problem identified, we now have the solution

We believe this observation is the reason high-efficiency cells have only previously been explored using expensive silicon. Past researchers were unaware of the sensitivity of p-type wafers to degrade and did not have the knowledge to overcome it.

Fortunately, we now know the bonding of boron and unwanted oxygen in the silicon wafer causes this degradation. Treatments with a high-intensity laser have been shown to stabilise cells in a matter of seconds.

The laser illumination can make hydrogen, which is already floating around in the silicon, more mobile to move around and “passivate” the unwanted boron-oxygen defects. Exactly how hydrogen does this is still an active area of research, but we know it solves the problem. Our research confirms a short laser treatment can stabilise the performance of p-type silicon heterojunction solar cells.

Armed with this new knowledge, we can further develop high-efficiency technologies with cheaper raw materials. This will reduce the cost of every watt of solar electricity produced. In March this year, solar panel manufacturer LONGi Solar announced an efficiency of 25.47% for a silicon heterojunction solar cell made using p-type wafers.

To see manufacturers making high-efficiency solar cells that are potentially cheaper means our findings have a tangible impact on industry. Reducing solar cell costs will provide cheaper electricity to millions of consumers while addressing climate change.

Jacinda Ardern’s popularity has fluctuated over the past five years, with the prime minister’s approval peaking at 76% in May 2020. Those early rises in popularity were met with warnings about the risks of placing a political leader on a pedestal. Some even labelled the phenomenon of “Jacindamania” a personality cult or branded Ardern “a cult of personality politician”.

But this description not only misrepresents Ardern and her popularity – it also dilutes the concept of a “personality cult”, overlooking several of its defining characteristics.

My research explores the difference between mere popularity and personality cults. This work is important as commentators and media increasingly conflate the two ideas.

By definition, a personality cult parallels religious worship, elevating an individual’s authority “through the deliberate creation, projection and propagation of a godlike image”.

A personality cult also entails a specific set of social practices including inflated flattery and toadying, immunity from delegitimising crises and entrenched rituals.

In the contemporary context, the label of personality cult has been more accurately applied to leaders like Russian president Vladimir Putin and former US president Donald Trump.

Debunking the myth of the cult

While a personality cult can develop organically from the general population, it equally needs to be cultivated from above to be used as an instrument of power.

Over the past few years, artists have depicted Ardern as Wonder Woman and as pop cultural figures like Star Wars’ Princess Leia or Rosie the Riveter from WWII marketing imagery.

But there have been no official attempts from Ardern or the government to depict her as a hero – in stark contrast to how both Trump and Putin have contributed to their own glorification.

Trump, for example, photoshopped an image of his face on Rocky Balboa’s body and posted it on social media. The Russian government has released numerous official photos of Putin riding around bare-chested in the Siberian wilderness, cultivating an image of the leader as the ideal Russian man.

No shameless toadying

The most significant differences between Ardern’s popularity and a fully-fledged personality cult can, however, be found in how the public responds to exaggerated depictions of their leader.

Chechen leader Ramzan Kadyrov called Putin a hero “appointed by Allah” who everyone should bow down to. Former US Secretary of Energy Rick Perry compared Trump to biblical kings, calling him “the chosen one, sent by God to do great things”.

In contrast, the praise Ardern receives is less inflated and excessive.

And while some argue that Ardern’s halo has blinded her fans to deeper problems, her supporters are not completely blind to her mistakes and shortcomings, with marked fluctuations in approval polls that coincide with her political successes and failures.

Inflation, Omicron and a straining health system have all eroded support for Ardern and the Labour party. Unlike what would be expected with a personality cult, her popularity is not immune to strong political headwinds.

Absence of rituals

In terms of more traditional cult-like behaviour, a personality cult also entails a ritualistic element.

After Putin unexpectedly stopped in the village of Izborsk, his path through town was marked, along with the places he had bought cucumbers, drunk from the fountain, and touched a tree and made a wish.

Magnitogorsk Museum likewise exhibited the overalls he had worn during his visit. Visiting these locations have become a matter of pilgrimage for his followers.

What kind of person joins a cult or joins a terror group?

Such behaviour has been absent around the New Zealand prime minister.

Admittedly, Ardern’s weekly updates from her home during the COVID-19 lockdown in 2020, covering everything from serious political matters to her daughter’s nap time, could be reminiscent of a ritual, given it engaged people in an activity revolving around her.

However, the weekly updates didn’t originate at the grassroots level, unlike the hero worship of Putin, and their absence has been largely inconsequential for the community.

Explaining ‘Jacindamania’

“Jacindamania” illustrates how popularity and a few hero-like depictions are not enough to constitute a fully-fledged personality cult.

That Ardern’s popularity hasn’t manifested itself into social practices and thus transformed into a personality cult, means that she has less authority than is suggested by some commentators.

Ardern can’t use her popularity to make her supporters follow orders blindly. Even loyal Labour voters challenge her political direction.

Trump, on the other hand, encouraged his supporters to unlawfully storm the Capitol in an attempt to overturn the 2020 presidential election results. Recent congressional hearings found these supporters rioted after being encouraged by Trump and stopped when Trump told them to go home.

Tall poppy syndrome could be a barrier

Calling the phenomenon surrounding Ardern a cult thus grossly overestimates the extent of her power – and clashes with New Zealand culture.

With their perception of the country as an egalitarian society and the prevalence of the so-called “tall poppy syndrome”, New Zealanders are arguably less predisposed to worship or elevate a single individual.

New Zealanders’ innate modesty and tendency to downplay achievement are not conducive to the cultivation of a cult from above – or below.

So, while Ardern has experienced waves of popularity both domestically and on the global stage, her support is far from entering the territory of the personality cults surrounding Putin or Trump. She is popular, sometimes, but not infallible.

The universe is littered with galaxy clusters – huge structures piled up at the intersections of the cosmic web. A single cluster can span millions of light-years across and be made up of hundreds, or even thousands, of galaxies.

However, these galaxies represent only a few percent of a cluster’s total mass. About 80% of it is dark matter, and the rest is a hot plasma “soup”: gas heated to above 10,000,000℃ and interwoven with weak magnetic fields.

We and our international team of colleagues have identified a series of rarely observed radio objects – a radio relic, a radio halo and fossil radio emission – within a particularly dynamic galaxy cluster called Abell 3266. They defy existing theories about both the origins of such objects and their characteristics.

Relics, haloes and fossils

Galaxy clusters allow us to study a broad range of rich processes – including magnetism and plasma physics – in environments we can’t recreate in our labs.

When clusters collide with each other, huge amounts of energy are put into the particles of the hot plasma, generating radio emission. And this emission comes in a variety of shapes and sizes.

“Radio relics” are one example. They are arc-shaped and sit towards a cluster’s outskirts, powered by shockwaves travelling through the plasma, which cause a jump in density or pressure, and energise the particles. An example of a shockwave on Earth is the sonic boom that happens when an aircraft breaks the sound barrier.

“Radio haloes” are irregular sources that lie towards the cluster’s centre. They’re powered by turbulence in the hot plasma, which gives energy to the particles. We know both haloes and relics are generated by collisions between galaxy clusters – yet many of their gritty details remain elusive.

Then there are “fossil” radio sources. These are the radio leftovers from the death of a supermassive black hole at the centre of a radio galaxy.

When they’re in action, black holes shoot huge jets of plasma far out beyond the galaxy itself. As they run out of fuel and shut off, the jets begin to dissipate. The remnants are what we detect as radio fossils.

Explainer: radio astronomy

Abell 3266

Our new paper, published in the Monthly Notices of the Royal Astronomical Society, presents a highly detailed study of a galaxy cluster called Abell 3266.

This is a particularly dynamic and messy colliding system around 800 million light-years away. It has all the hallmarks of a system that should be host to relics and haloes – yet none had been detected until recently.

Following up on work conducted using the Murchison Widefield Array earlier this year, we used new data from the ASKAP radio telescope and the Australia Telescope Compact Array (ATCA) to see Abell 3266 in more detail.

Our data paint a complex picture. You can see this in the lead image: yellow colours show features where energy input is active. The blue haze represents the hot plasma, captured at X-ray wavelengths.

Redder colours show features that are only visible at lower frequencies. This means these objects are older and have less energy. Either they have lost a lot of energy over time, or they never had much to begin with.

The radio relic is visible in red near the bottom of the image (see below for a zoom). And our data here reveal particular features that have never been seen before in a relic.

Its concave shape is also unusual, earning it the catchy moniker of a “wrong-way” relic. Overall, our data break our understanding of how relics are generated, and we’re still working to decipher the complex physics behind these radio objects.

Ancient remnants of a supermassive black hole

The radio fossil, seen towards the upper right of the lead image (and also below), is very faint and red, indicating it is ancient. We believe this radio emission originally came from the galaxy at the lower left, with a central black hole that has long been switched off.

Our best physical models simply can’t fit the data. This reveals gaps in our understanding of how these sources evolve – gaps that we’re working to fill.

Finally, using a clever algorithm, we de-focused the lead image to look for very faint emission that’s invisible at high resolution, unearthing the first detection of a radio halo in Abell 3266 (see below).

Towards the future

This is the beginning of the road towards understanding Abell 3266. We have uncovered a wealth of new and detailed information, but our study has raised yet more questions.

The telescopes we used are laying the foundations for revolutionary science from the Square Kilometre Array project. Studies like ours allow astronomers to figure out what we don’t know – but you can be sure we’re going to find out.

We acknowledge the Gomeroi people as the traditional owners of the site where ATCA is located, and the Wajarri Yamatji people as the traditional owners of the Murchison Radioastronomy Observatory site, where ASKAP and the Murchison Widefield Array are located.

The Albanese government is moving ahead with plans to hold a first-term referendum on a First Nations Voice. The Prime Minister has attended the annual Garma Festival in northeast Arnhem Land, where the Voice was a key focus.

The referendum will ask voters to enshrine in the Australian Constitution a First Nations body that would give non-binding advice to the federal parliament on laws and policies affecting Aboriginal and Torres Strait Islander peoples.

In recent weeks there has been growing debate on whether Australians need to see the full detail of the proposed advisory body before voting on it. Megan Davis, one of the architects of the process that preceded the Uluru Statement from the Heart, says voters should be asked to approve the body’s basic purpose and function, and other details can be filled in later by parliament.

Critics of this approach, including Marcia Langton, argue a specific model should be outlined in draft legislation and tabled in parliament before the referendum.

The question of whether proposals should be general or specific is a familiar issue in referendum design. So, how much detail should referendum proposals contain? And is there a risk that proposals that are too detailed, or too vague, can end up being rejected by voters?

Ensuring an informed vote on the Voice

For the First Nations Voice, the priority should be to develop a proposal that is sufficiently clear and detailed to enable Australians to cast an informed vote. Recent public statements from leading figures suggest this will occur.

As Megan Davis explains, Australians are being asked to approve a constitutional amendment that will enable the creation of the Voice. This could be in the form of a new constitutional provision that sets out the basic function and purpose of the First Nations advisory body.

It was always intended that detail on matters such as size, composition and resourcing would be left to the parliament. This recognises parliament’s supremacy in our constitutional system. It also enables the Voice to be tweaked over time in response to new circumstances. If a specific model appeared on the ballot paper, or was tabled in parliament before the vote, the flexibility and adaptability of the Voice would be undermined.

If Australians are to cast an informed vote, though, it is important they have a clear sense of what will happen if this new advisory body is approved.

Senator Pat Dodson recognises this. Earlier this week he announced the Labor government will, by the end of the year, release an exposure document that sets out key elements of the Voice.

Davis says the proposed constitutional amendment will be supplemented by other material to give Australians a clear idea about what they are voting on. This will include a set of design principles to guide decisions on matters of detail. It will also include a blueprint for the process that the government and parliament will follow to implement the Voice if voters approve it.

Taken together, these steps empower and respect voters, enabling them to cast an informed vote at the referendum.

The importance of clear proposals

One of the basic requirements of a fair referendum is voters have access to adequate information about the proposal. People can only cast an informed vote if they understand the nature of the proposal and what will happen if it is approved.

This is reflected in the Venice Commission’s Code of Good Practice on Referendums, a set of recommended standards on referendum conduct. The Code says “the question put to the vote must be clear”.

The dangers of unclear referendum proposals were demonstrated in 2016 when British voters were asked whether the United Kingdom should remain in, or leave, the European Union. It was never made clear to voters what would happen if “leave” prevailed. After “leave” won, years of post-referendum confusion followed as parliament argued over what the result meant and how to implement it.

The Australian Constitution protects against vague referendum proposals of this kind. Its special amendment procedure requires a “proposed law” be submitted to voters. This takes the form of a Bill that sets out the specific changes to the constitutional text if the referendum is successful. When the people vote Yes, those changes are made to the Constitution automatically.

Governments sometimes publish additional material to help voters understand what will happen if a referendum proposal is carried. In the lead up to the 2014 Scottish independence referendum, for instance, the Scottish government published a lengthy White Paper on its plans for independence and the process it would follow if the referendum was successful.

Can the amount of detail affect the result?

There has not been any systematic study of whether the amount of detail in a referendum proposal affects its chances of success.

It seems intuitive that vague proposals pose risks, as opponents can exploit the lack of detail to stoke fear about what might happen.

But highly detailed proposals also have their strategic drawbacks. Adversaries can pull apart the details, focusing attention away from a basic reform idea that may enjoy widespread support.

Recent referendum experience suggests there is no clear relationship between detail and success. It is thought Ireland’s 2013 referendum on abolishing the upper house was defeated, in part, because the consequences of the proposal were unclear. On the other hand, in 2016 a majority of UK voters embraced the vague idea of leaving the EU.

Closer to home, in 1999 Australians were presented with a highly detailed proposal for establishing a republic with an appointed president. Opponents attacked the specifics of the model, contributing to its defeat.

Public education will be crucial

Looking ahead, we need to keep in mind that getting the proposal right is just one element of fostering informed voting at a First Nations Voice referendum.

As the referendum approaches, we need to ensure voters have access to clear, accurate and balanced information about the specific proposal and the wider constitutional system.

This can be achieved through a mix of initiatives, including an informative official pamphlet, a neutral education campaign, and public subsidies to ensure both sides have an opportunity to present their arguments.

As we debate what shape the referendum proposal should take, we must not lose sight of the other ways that we can support Australians to cast an informed vote on this important issue.

If politics really is to be done differently, as Prime Minister Anthony Albanese has promised, then the way politics is reported will need to be done differently too.

This is because the media’s power to portray will determine how the electorate perceives whether change is happening.

It is a reciprocating process. The way politicians perform influences the media’s portrayal of them, and how the media portray politicians in turn influences political practice.

One benchmark for helping us assess whether the promised change materialises is provided by academic Judith Brett’s characterisation of the Morrison administration:

The blame shifting, the careless inattention, the failure to prepare, the blatant favouring of Coalition and marginal seats with government largesse, the focus on announcements with little follow-up, the absence of serious concern about corruption and integrity […]

But that benchmark takes into account only the performance of the politicians. What about the media?

The media do appear to be in the early stages of changing the way they report federal politics. But this change is tentative, patchy and uncertain.

For instance, the coverage of the government’s actions on foreign policy has on the whole been straightforward and informative. That was until someone in the media pack travelling with Albanese in Europe asked why the prime minister’s visit to Ukraine was not equivalent to Morrison’s holiday to Hawaii during the 2019 bushfires. Albanese slapped down the comparison as “offensive”.

The on-the-road media pack had a bad election campaign disfigured by exactly this kind of juvenile “gotcha” reporting. Clearly in some parts of the media, the atmosphere of anticipated change has not penetrated.

In other parts of the media it clearly has, but there is an undercurrent of tentativeness, understandably so. Politics done differently suggests politics with fewer culture wars, fewer scandals, more policy focus, more incrementalism.

Moreover, a good deal of ideological steam has gone out of the political discourse as issues such as religious freedom, Safe Schools and transgender discrimination have faded from view. Climate change is now accepted by enough mainstream politicians, and media, to make the remainder look like cranks.

There has also been a dramatic structural change in the composition of the parliament, with the crossbench now representing a powerful third force. How will the media adjust from two-horse politics, so the crossbench gets a voice commensurate with its level of representation?

How the ‘reality-distorting machinery’ of the federal election campaign delivered sub-par journalism

All this implies the need for a shift in the priority given by the media to the various news values that turn content into news. Two of the most powerful news values, negativity and conflict, have been in plentiful supply since the collapse of the Rudd prime ministership in 2010.

Politics done differently, with a focus on policy formulation and implementation, makes the news values of impact and significance more salient. But this is not the stuff of clickbait, eyeballs, social media agitation and tabloid headlines.

This is a challenge at a time when every click and eyeball counts for a media industry still trying to recoup some of the devastating financial losses inflicted by the internet.

Will editors and news directors – and media proprietors – be up for the challenge? It is too soon to say. Conflict or negativity can always be manufactured, so there is no guarantee a more civilised and constructive political conversation will be reflected in more civilised and constructive coverage.

However, there are a few early signs of recognition in the media that change is in the air.

Author and freelance journalist Julie Szego seems to be onto it. In a column for The Age, she made the sardonic observation that Australian politics was suddenly boring. Once upon a time, she wrote, it was like the Danish TV drama Borgen, a world of cheap publicity stunts, the selling out of cherished principles, and morally bankrupt spin where a prime minister “creepily” washed a woman’s hair for a photo op. “But now it is all one big yawn.” Yet this was worth celebrating, she said, because it had produced a “background hum of steady-as-she-goes, the not un-genuine bid for consensus, the incremental steps toward something better”.

Covering the first sitting day of the 47th parliament, The Australian on its front page tried kicking life into the issue of construction union thuggery, based on a parliamentary question from a Liberal backbencher. But its editor-at-large, Paul Kelly, wrote reflectively on the need for competence in government and for Albanese to break the cycle of first-term failure.

Katharine Murphy, writing in The Guardian Australia, described the first day of the new parliament as conveying “a sense of a corner being turned”.

She noted that Scott Morrison was absent, preferring to attend a conference of conservative politicians in Tokyo. This was perhaps for the best, she added, since the style of politics he indulged in had been “repudiated in myriad ways”.

Whether this change in atmospherics illustrated by these examples of the newspaper coverage percolates into television news is an open question.

However, if change is to occur in how politics is portrayed to the public, the performance of television is crucial. This is because television news is still the most general source for Australian news consumers, with 66% saying they watch TV news and 42% saying it is their main source of news.

À lire aussi :
How much do mainstream media matter in an election campaign? (Spoiler: more than you might think)

Television news is also the most formulaic of all professional mass media: tight scripts allied to footage that may or may not assist the viewer’s understanding, and grabs of people speaking, all compressed into short packages. There is little scope for reflecting anything except the most superficial elements of a story.

Even so, the wording of scripts, the way they are read, and the choice and juxtaposing of grabs do allow for change to be reflected.

Regardless of the medium, absorbing and implementing change like this takes effort, and the difficulty of breaking old habits should not be underestimated. Journalists and audiences alike are accustomed to established ways of telling stories, just as medieval minstrels and their audiences were. No departure from the established script is easily tolerated.

But if it turns out that tomorrow’s politics are indeed done differently, it would be a serious disservice to the public if the media overlaid on them the news template of yesterday.

Australia has only a handful of specialists familiar with managing what happens when the nervous system can’t properly regulate the body, as sometimes occurs with long COVID. While long COVID clinics are being set up, there are no government-funded clinics for this type of nervous system dysfunction and private waiting lists are now long.

From the outset, long-COVID sufferers faced the same prejudice experienced by patients before them who sought assistance through Centrelink and the National Disability Insurance Scheme for the effects of post-infection conditions.

Disability insurance schemes worldwide are driven by definitions and checklists that allow non-medical workforces to assess and approve candidates for support services. But those with “invisible illness” rarely meet these criteria.

If we are to manage the tidal wave of impairment and disability bearing down on us, policymakers must heed the warnings that have been sounding for the past two years. We’ll need to rethink disability and support.

We need to brace for a tsunami of long COVID. But we’re not quite sure the best way to treat it

First warnings

In November 2020, data later published in The Lancet were presented to the Chinese Academy of Medical Sciences. The researchers warned of persistent symptoms after COVID, including fatigue, cognitive dysfunction, palpitations, chest pain, depression, insomnia and headache.

The colloquial term “long COVID” was soon coined. Varying iterations of the name followed (including “COVID long haulers” in the United States). Many clinicians use the more scientific descriptor, “Post-acute sequelae of COVID-19”.

Long COVID is not a new phenomenon. Various post-infection illnesses have been documented in medical literature for decades.

And such conditions bear a striking resemblance to each other. First, an individual is knowingly (or unknowingly) exposed to a pathogen (a virus, bacterium or other microorganism). An acute illness of varying degrees of severity ensues before a partial or complete recovery. But following “recovery”, a broad range of symptoms emerge. And these lead to functional decline. In other words, they stop the sufferer from doing the daily activities they would normally be able to do.

Two of these conditions, postural orthostatic tachycardia syndrome and myalgic encephalomyelitis or chronic fatigue syndrome, appear closely related. And their symptoms look a lot like long COVID too. Both seem to affect more women than men and additional immune problems are often present.

These similarities support the theory these illnesses result from a hyper-vigilant immune system. This creates an immune response that inadvertently causes damage to the fragile autonomic nervous system (which regulates the body’s normal functions like heart rate and blood pressure) while attempting to rid the body of the invading pathogen.

However, there are a plethora of other theories and more investigation is needed.

An old stigma

Lack of understanding about these syndromes is reflective of the broad stigmas attached to them – the idea they are psychosomatic and involve the mind and body.

The origin of these stigmas can be traced to a series of publications in the latter half of the 20th century that addressed outbreaks of illnesses after exposure to unknown pathogens.

In 1970, the British Medical Journal published an article authored by two psychiatrists who had reviewed the case notes of 198 patients from the Royal Free Hospital in North London, where an outbreak of an unknown pathogen had occurred 15 years prior. The authors determined the disease had no identifiable organic origin and was therefore likely to be caused by “epidemic hysteria”. This conclusion was partly justified by the high proportion of women among those infected with the illness, the authors said.

Publication of this theory in a preeminent scientific medical journal gave credence to what became an enduring narrative. The result has been a chronic lack of interest and investment in these debilitating invisible illnesses, which can render people unable to work or participate in society.

A question of definition

The burden of these systemic failings now weighs heavy on a society faced with a worldwide tsunami of post-COVID conditions. And it goes some way to explaining the collective shrugging of shoulders by health authorities when it comes to providing answers for sufferers.

Estimates of how many people infected with COVID go on to develop long COVID vary from 5–40%. The large variance is a result of the initial absence of a consistent or unifying set of diagnostic criteria.

Recently the World Health Organization provided a definition of post-COVID conditions. It includes those with a history of likely or confirmed infection with SARS-CoV-2 (the virus that causes COVID) who experience lingering symptoms for longer than two months, which are unexplained by an alternative diagnosis.

Defining the illness allows clearer characterisation of who is affected. Long COVID is now known to affect any age group and may be unrelated to initial infection severity. This evidence prompted the US Centers for Disease Control and Prevention to detail an ominous warning about post-COVID health problems that “can last weeks, months, or years”.

Multiple case series and observational studies have now identified a high burden of nervous system dysfunction in long COVID patients. Several studies, including one published in the Journal of the American College of Cardiology, demonstrated up to 95% of long-COVID patients also meet the international criteria for postural orthostatic tachycardia syndrome. This syndrome can cause lightheadedness, brain fog, fatigue, headache, blurred vision, palpitations, tremor and nausea.

These symptoms often are often incompatible with carrying out normal daily tasks, which explains why unemployment and disability are high among postural orthostatic tachycardia syndrome patients, despite their young age.

The next wave

Back in March 2021, the American Autonomic Society released a statement warning of the rising presentations of patients to autonomic specialist referral centres with symptoms of post-COVID postural orthostatic tachycardia syndrome. Of particular concern was the insufficient number of physicians familiar with this type of dysfunction to treat the condition.

This situation is mirrored in Australia where only a handful of specialists are familiar with managing such complex cases.

Contrary to popular medical opinion and widely held beliefs, effective therapies exist for underlying conditions like postural orthostatic tachycardia syndrome, which is prevalent in long COVID. Early intervention is key. Treatment needs to be fully explored and implemented before disability support services can be sought.

Time to listen

Our health systems need to absolve themselves of past sins and pay attention to the overwhelming voice of the current sufferers of long COVID and those with other post-infection syndromes or invisible illnesses who have endured decades of medical neglect.

Treatment options need to be made available and multidisciplinary teams need to upskill to manage these conditions.

A redefining of what it is to be disabled needs to be explored. Most importantly, these definitions should not be tied to a single cause but to the manifestation of symptoms that culminate in the disability.

The Albanese government has introduced tax cuts to electric vehicles in its first sitting week, claiming the proposed changes would be “good for motorists, good for climate action and good for fleet purchases”. They won’t, however, help most Australians afford one.

Labor plans to stop the “fringe benefits tax” applying to electric vehicles. This tax usually applies to all cars provided by an employer to an employee, either as part of a salary sacrifice arrangement or as a company car available for personal use. This means the winners of the tax change are high-end employees who can afford a high-priced electric vehicle such as a Tesla.

Rolling business fleets over to the secondhand market is an important way to make electric vehicles more affordable to everyday people. But this tax cut won’t see this happen anytime soon.

Our recent report recommends a suite of other tax changes to lower electric vehicle prices and ownership costs. Australia can’t meet its target of 89% new car sales being electric by 2030 without significantly reforming the transport sector. Labor’s new tax cut is a far cry from what’s needed.

What does a fringe benefits tax do?

Australia’s transport sector accounts for around 18% of national emissions. Electric vehicles, powered by renewable energy, are crucial for meeting Australia’s emissions target of net-zero by 2050.

This won’t happen if electric vehicles remain prohibitively expensive. Indeed, 87% of Australians in a 2021 survey said the biggest barrier to buy an electric vehicle is its high upfront cost.

So what does a fringe benefit tax on cars actually do?

There are two ways the fringe benefit tax is calculated in Australia: using the statutory formula (based on the car’s cost price), or using the operating cost method (based on the costs of operating the car). The fringe benefits tax is 47% of each method’s calculated final value, known as “grossed up taxable value”.

The highest payable fringe benefits tax is under the statutory formula method, which applies when employees fail to keep a car logbook. Under this method, electric vehicles would be at a disadvantage.

Employees would be penalised for choosing an electric vehicle because of its higher upfront cost price. Employers would pay a higher fringe benefits tax than if they’d bought a lower-priced petrol or diesel car. That doesn’t leave much incentive for businesses to buy an electric car.

Removing the fringe benefits tax on electric vehicles is a good way to stop penalising employees for choosing an electric vehicle. But it still won’t reduce the high upfront cost price.

Why businesses still won’t choose electric cars

Business uptake of electric vehicles depends on the total cost of ownership. Let’s use Hyundai’s Kona cars as a case study.

Modelling found Kona electric cars, including a smart charger, costs A$66,337 (excluding GST). A new Kona fuel-combustion car, on the other hand, costs $31,329 (excluding GST), which means electric vehicles are not cost competitive.

The fringe benefits tax would further widen this cost gap of over $35,000, adding around $12,000 each year to the Kona Electric.

Labor’s bill would remove the $12,000 yearly tax, reducing the ownership cost of an electric vehicle. But it will not reduce the upfront price difference with Kona’s fuel-combustion car.

Another factor to consider is that a 2020 survey found over 47% of business fleets used for work are parked at home and subject to fringe benefit taxes. This means the fringe benefit tax exemption does not apply to all business vehicles.

The fringe benefit tax exemption may encourage the 47% of business fleet vehicles parked at home to transition to electric vehicles. But this will require an additional cost of installing chargers. This can be expensive, non-tax deductible and subject to additional fringe benefits tax.

Can we buy from the second-hand market?

Australia should learn from tax changes in Europe, which have successfully accelerated the uptake of electric vehicles. Company cars represent the main market share for new electric vehicles in Europe.

The highest is in the Netherlands, where businesses account for 73% of new electric vehicle purchases. In the United Kingdom it’s at 67%, Germany at 49% and Norway at 34%.

After three to four years, these business electric vehicles are rolled over into the second-hand market, which are cheaper and more affordable to all consumers, not just high-end buyers.

In Australia, business buyers account for over 40% of new light vehicle sales. But their uptake of electric vehicles is shockingly low, with a mere 487 electric vehicles acquired by business fleets in 2020.

This means Australian consumers cannot rely on more affordable business fleet electric vehicles being rolled over into the secondhand market any time soon.

What should we do instead?

Our report finds the federal government must introduce additional tax changes, and not be limited to the fringe benefit tax exemption for electric vehicles.

We recommend 17 short-term and long-term tax changes to lower the upfront electric vehicle prices, the total cost of ownership and encourage home charging to address business lack of workplace charging infrastructure. These include:

• instant asset write off to only apply to employer-provided fleet electric vehicles, up to the luxury car limit of A$84,916 (including GST in 2022/23). This would allow the Kona electric vehicle purchase cost of $64,037 to be claimed as an outright tax deduction by a business in its first year of ownership.

• increase the GST credit and depreciation cost limit for fleet electric vehicles, up to the luxury car limit

• a fringe benefit tax exemption for home charging installation and smart charges for fleet electric vehicles

• instant asset write-off for home charging installation and smart charges for fleet electric vehicles.

Business incentives such as these will bring Australia a big step closer to meeting its 2030 electric vehicle target and, crucially, its net-zero emissions target.

The cereal bowl is sitting there getting mushy and gross. You ask your child to eat for the 20th time, but still they sit there, totally unwilling.

Eventually, there is simply no time left (the school bell will ring in three minutes) and you have to make a hasty exit out of the house. Maybe your child has eaten one or two mouthfuls, maybe they have had nothing. You and your kid are both cranky and stressed.

Does this sound familiar?

Unfortunately, eating breakfast really is important. So as parents, you do need to offer it and do need to try and make sure it is eaten.

But as a dietitian and a mum, I can assure you, it can be easier than this! How can parents get their kids to eat this important meal, without making it the most irritating part of the day?

3 reasons your teenager might skip breakfast – don’t fuss but do encourage a healthy start

How many kids skip breakfast?

Research tells us a lot of children don’t eat breakfast.

The most recent data we have is about ten years old. But as of 2011–12, close to 12% of boys and 15% of girls aged between two and 17 skip breakfast.

This increases with age. By the time children are 14 to 17, about 25% of boys and 36% of girls miss the meal. These results are somewhat similar to reported rates of breakfast-skipping around the world.

How important is the first meal of the day?

You have heard it before and that’s because breakfast really is important.

As research shows, skipping breakfast has been associated with lower diet quality.

For example, 2018 US research on children aged two to 12 who skipped breakfast on the day of study found 36% of their daily energy intake came from snacks compared to 29% in those who ate breakfast.

Breakfast skippers also had lower intakes of fibre, folate, Vitamin A, iron and calcium – all critical nutrients for physical and mental growth and development in children – than kids who did eat breakfast. Their intake of processed and ultra-processed foods was also higher.

A review of 16 studies in children and adolescents also indicates skipping breakfast in this age group is linked with more risk of obesity and being overweight. And this can lead to an increased risk of type 2 diabetes in children.

A study which looked at breakfast consumption in children and then followed them into adulthood found if they continued to skip breakfast they had higher risk of detrimental effects on their heart health and diseases such as metabolic syndrome and diabetes.

It is also important for learning

Skipping breakfast means there is not enough glucose in the body (from breaking down carbohydrates), which is what the brain prefers as its energy source. Glucose provides the energy for messaging between the brain cells and helps to make neurotransmitterss (chemical messages in the body).

Studies also show children who eat breakfast regularly perform better academically than those who skip it. In particular, skipping breakfast impacts on their memory and the number of errors on attention tasks.

This effect on achievement is more pronounced for those children who don’t eat enough nutritious food overall. Interestingly school breakfast programs lead to improvements in academic ability, but it is thought this may be because children attend school more.

Why don’t kids want to eat breakfast?

A 2014 study conducted in Australia and England tried to identify why adolescents skip breakfast. This found teenagers said they did not have time, were not hungry or did not enjoy breakfast. Only a small percentage reported skipping breakfast to control weight.

A 2019 study in the United States of kids aged six to 11 asked both parents and children why they think children skip breakfast.

Respondents said lack of time and feeling rushed was the main reason.

In this study, they were also asked to identify what may help. Children suggested having a set morning routine and also selecting breakfast foods ahead of time.

The children also said that parents needed to continue to encourage them to eat breakfast. Parents were in agreement with these suggestions from the children but also said using “grab-and-go” products would also help.

Parents also said avoiding distractions – like books and phones – was important.

What can parents do?

1. Allow enough time

This will come as no surprise to parents, but we need to make sure kids have enough time to eat. This means getting up early enough and having a routine in the morning that makes time for breakfast.

2. Be prepared

To save time and make it easier set the breakfast table the night before. Get it ready with crockery, cups and cutlery, and put out the foods that won’t spoil overnight such as their favourite wholegrain cereal, spreads for toast and wholegrain bread.

3. Have a decent selection

Give your kids good options and make them feel like they have a choice. Ensure you have a range of healthy and easy breakfast options that your children like.

This can be traditional breakfast options like wholegrain breads and breakfast cereals, fruit toast, yoghurt and cut up or frozen fruit. Porridge, particularly in winter, is great as it can cook itself in the microwave.

Offering smoothies with fruit, yoghurt, milk and oats may be appealing to adolescents.

4. Think outside the (cereal) box

There are no rules around what sort of healthy foods can be eaten at breakfast. The important thing is that they are from the Australian Dietary Guidelines.

Some may find healthy leftovers from dinner appealing or even a sandwich with avocado and salad fillings, or cold meats like chicken or tuna. Of course a cooked breakfast with wholegrain toast, eggs and veggies (avocado, mushrooms, tomatoes, spinach) is excellent, but this is not a quick option!

5. Get rid of distractions

Make sure your kids can just focus on eating. This means no TVs, devices, toys or books.

6. Do it yourself

Remember children are great imitators. So, if they see parents eating breakfast they are more likely to do it as well.

7. Have a back-up

If these ideas still don’t work and you have had one of those mornings where nothing goes right, then you could consider grab-and-go options.

These don’t have to be commercial products either – think of smoothies, toast, previously homemade savoury muffins or banana bread (that are perhaps stored in the freezer for these occasions) or a piece of fruit.

Should we eat breakfast like a king, lunch like a prince, and dinner like a pauper?

8. But be careful about muesli bars

Muesli bars can be an option, but make sure you look for ones that are low in sugar (less than 15 grams per 100 grams), low in saturated fat (less than 1.5 grams per 100 grams) and high in fibre (more than four grams per 100 grams). Remember if the bars contain fruit and nuts in them, the level of sugar and fat will go up, but this is not problematic as it is not added sugar or fat.

So, set yourself and you children up for successful breakfasts, and who knows? You may even enjoy the family eating together.

With the Australian Energy Market Operator (AEMO) warning consumers of huge price hikes ahead, further calls for the federal government to pull its so-called “gas trigger” seem inevitable.

But that could be a very big mistake – leading to the type of trade dispute Australia fought for years against Big Tobacco over plain packaging laws.

The gas trigger (officially the Australian Domestic Gas Security Mechanism) was created by the Turnbull government in 2017 when there were fears of a gas shortage in eastern Australia.

It allows the federal resources minister to direct gas exporters to limit their gas exports or find new sources of gas to meet domestic demand instead of exporting gas overseas.

À lire aussi :
Why did gas prices go from $10 a gigajoule to $800 a gigajoule? An expert on the energy crisis engulfing Australia

To trigger the mechanism, however, requires predictions of insufficient supply, not just higher prices. It is therefore useless for dealing with the sort of short-term issues besetting eastern Australian gas markets, and has never been triggered.

The mechanism had been due to expire at the end of 2022. It was meant to be a temporary measure, not a permanent crutch in lieu of more sustainable solutions. But the government is keen to keep it. Resources Minister Madeleine King said it will be extended to 2030.

But should it?

There’s no doubt the trigger gives the government some leverage over the gas industry, in much the same way that pointing a gun at someone gets their attention.

Actually pulling the trigger, however, is a different matter. It may have serious unintended consequences, potentially breaching Australia’s commitments under various trade and investment treaties.

How the gas trigger works

An example of the extra regulatory leverage the gas trigger has given the federal government is its 2021 agreement with three major east-coast liquefied natural gas (LNG) plants: Australia Pacific LNG, Gladstone LNG and Queensland Curtis LNG.

Under this deal, the suppliers promised not to sell uncontracted gas internationally without first offering equivalent volumes to the domestic market.

What would happen if the gas trigger was actually pulled?

Then the mechanism becomes an export control measure, compelling gas companies to limit their exports or find new sources of gas to offset the shortfall.

In that circumstance, foreign-owned gas companies could use free-trade agreements to take Australia to a notoriously expensive “investor-state dispute settlement” process to claim compensation for what is known as indirect expropriation.

What is indirect expropriation?

Simply put, expropriation is any interference by governments with the rights and properties of foreign investors.

It can be direct, such as outright seizure of investors’ properties, or indirect, through enactment of laws or regulations that interfere with investors’ capacity to generate revenue or do business.

Australia has signed several investment treaties and free-trade agreements that contain investor-state dispute settlement provisions. If the government pulls the gas trigger, a foreign-owned gas company could seek compensation for interference with the company’s right to export gas to its overseas buyers.

That is a concern, given Australia’s LNG sector is 95.7% owned by foreign investors according to the Australia Institute.

For example, Malaysia’s Petronas and Korea’s KOGAS are major shareholders in Gladstone LNG.

These foreign companies have rights under international trade and investment rules, multilateral agreements such as the ASEAN-Australia-New Zealand free trade agreement, and bilateral free-trade agreements signed with Malaysia and Korea.

The results won’t be pleasant

Disputes involving indirect expropriation are expensive and time-consuming.

The classic example is Australia’s six-year defence of its tobacco plain-packaging laws against the global tobacco giant Philip Morris.

À lire aussi :
When even winning is losing. The surprising cost of defeating Philip Morris over plain packaging

Among other things, Philip Morris claimed the labelling regulations indirectly expropriated its brand assets, intellectual property and goodwill associated with its products. Australia eventually won the dispute, but at a reported A$24 million cost along with internal expenditures.

The risk of foreign gas investors making indirect expropriation claims is quite real. They have invested in extracting Australian gas to meet demand in markets such as South Korea and Malaysia.

For example, Santos, the lead developer of the Gladstone LNG project, signed a 20-year agreement with KOGAS in 2010 to supply 3.5 million tonnes a year of LNG. This amounts to 11% of Korea’s domestic LNG supply.

Electricity generators have already lodged claims for compensation over AEMO interventions in the energy market. We shouldn’t expect gas suppliers to do less.

So what now?

We need a better solution to provide affordable gas and electricity prices along with reliable supply.

Some experts have advocated for a Western Australian-style gas reservation model to be implemented nationally. This model requires gas producers to reserve supplies for the local market before other transactions.

It will take time to introduce the model nationally without also inviting expropriation claims. Existing supply contracts will need to be exempt – and these, such as the Gladstone LNG contract to supply Korea, are often decades long.

But as new contracts are signed, the reservation model can eventually provide the benefits it now gives to West Australian consumers.

It’s not the short-term solution we’d all like. But it is a better solution than extending the gas trigger. The work to introduce it should begin now.

Since late 2020, the La Niña climate pattern has led to two years of above-average rainfall across much of Australia, and severe floods in parts of the country.

In areas spared the flooding, this rainfall has been good news for farmers, with improved conditions and high prices driving production and profits to record highs.

But the next drought is rarely too far away. For a reminder, we only need to look overseas, where the same La Niña weather system is combining with climate change to produce severe droughts in the United States, eastern Africa and South America.

Unfortunately, drought can be difficult to define and measure. Determining whether a region or farm is “in drought” is a longstanding and complex problem, which remains important to our future drought response.

Drought is about more than rainfall

For a long time, Australia’s standard measure of drought has been rainfall. But while rainfall indicators are easy to produce and interpret, they can be a poor measure of a farm’s prospects.

For one thing, the impact of drought depends on the timing of rain.

Even when the year’s total rainfall is okay, if most of it arrives at the wrong time of year (such as outside the crop season) it can have the same impact as a drought.

Temperatures are also increasingly important, with record heat waves having an important effect in recent years.

The story gets more complicated still when droughts affect the prices of inputs to farms. For example, during the 2018-19 drought many dairy farms were impacted by high hay and water prices, even where they received rain.

Measuring farm impacts

In response, researchers including myself at the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) have developed a new drought indicator based on predictions of farm financial outcomes, with some advantages over measures based on only rain.

In some cases it presents a very different picture.

In the example below, for 2018-19, the indicator shows more severe impacts in parts of New South Wales than the rainfall model (because low rainfall was compounded by high temperatures and input prices), and less severe impacts in Western Australia (partly because of high grain prices resulting from shortages on the east coast).

Rain-based indicator:

Model-based indicator:

Drought declarations are mattering less

Since the early 2000s, drought policy has evolved away from in-drought support of farm businesses to an approach that emphasises preparedness and resilience, making explicit drought “declarations” less common.

While this change has been welcome, it also led to a reduced focus on drought impact measurement (with the exception of some state-level systems).

But as recent droughts have shown, information on the extent and severity of drought impacts is still very important.

Helping farmers in drought distress doesn’t help them be the best

For one, it can help governments anticipate and prepare for increased demand for farm programs such as the Farm Household Allowance or the Rural Financial Counselling Service.

It can also help to better target resources for community, animal welfare or mental health drought impacts.

Better indicators can also support the development of new insurance products such as index-based weather insurance.

Such products are more likely to take off where indexes (and therefore payouts) can closely match real-world outcomes.

Early warnings are mattering more

While there is some evidence climate change has exacerbated recent droughts in Australia, there remains much uncertainty over the longer term effects.

Regardless, the potential for more extreme weather events is generally increasing the importance of early warning systems.

ABARES is working with the CSIRO and the Bureau of Meteorology to develop a Drought Early Warning System that will use this new indicator and a range of other tools to translate weather data into estimates of likely farm impacts.

Predicting these impacts remains very difficult, with challenges both in weather forecasting (particularly on monthly or longer time scales), and in translating these forecasts into agricultural outcomes.

But any improvements we can make will help us better respond to what the future has in store.

Aboriginal and Torres Strait Islander readers are advised this article contains names and images of deceased people. Archie Roach’s family have given permission for his name and image to be shared.

I am not sure of the first time I heard Archie Roach’s music.

Like most Aboriginal people born during or after the 1980s, we grew up listening to the person we affectionately called Uncle Archie. But there was one song that spoke to me from the first moment I heard it: From Paradise.

The song tells the story of a young girl who was taken away from her Country, the river lands, part of the stolen generations.

While his songs will play loud and long into the future, beneath his music Uncle Archie gave us something else, something deeply profound but mostly invisible.

He gave us – and all of Australia – an image of an Aboriginal man, tender and humble. An image long denied us.

Creating a constitutional Voice – the words that could change Australia

Our greatest storyteller

The passing of Archie Roach has hit us – Aboriginal and Torres Strait Islander people – like the first crack of thunder after dark clouds descend.

You know it’s coming, but it shocks you still.

Uncle Archie gave voice, a story, to the experiences of so many of our people. His song Took the Children Away gave shape to a suffering so deep and profound. “This story’s right, this story’s true,” he sang.

These cathartic melodies continue to offer us healing.

His catalogue of music spans distances and experiences difficult to grasp.
Uncle Archie’s gift was to write and bring to life through the strum of his guitar, the stories so familiar to us all.

His success took our stories to the nation, and the world.

To describe him simply as a musician fails to recognise him as a messenger.
His music reaches through darkness like the beam of a lighthouse, offering guidance and safe harbour in times of despair.

Through his life and love of music, Uncle Archie became our greatest storyteller.

The father and mentor

The music of Uncle Archie came from a place of suffering. Taken away as a child, being homeless, a drunk, locked up, learning of the death of family through whispers and letters, grief was his constant companion.

Through this time, he found Ruby Hunter. They would have two sons, Amos and Eban. Uncle Archie and Aunty Ruby, with their kids, shared a life of love, laughter and song. My personal favourite song, Down City Streets, was written by Aunty Ruby.

Uncle Archie has supported hundreds of young Aboriginal and Torres Strait Islander artists and inspired countless more through his foundation.

For decades Uncle Archie worked in youth detention centres, talking with young people who found themselves in hardship. He offered guidance and mentorship to young Aboriginal and Torres Strait Island people, illuminating a road through the difficulties of life, often the result of colonisation and racism.

He carefully navigated these spaces, acknowledging that while many young Aboriginal people, and especially boys, are born into a world that has been built to suppress them, they possess an inner strength stemming from culture and community.

Tell Me Why review: Archie Roach’s pain is the pain of all of us

Emu Man

Through his life, his dedication to Aunty Ruby, his devotion to his sons, his work with disengaged youth and his profound love for his people, Uncle Archie gave the nation an image of an Aboriginal man seldom found in the national psyche.

Images of the violent abuser, the drunk, the criminal, the absent father, or a combination of these, saturate our print media and television news bulletins. Even positive representations of Aboriginal men – the warrior, the sports star – exudes a sense of toughness and candour.

Rare, almost unheard of, are the stories of Aboriginal men as sensitive, soft, loving and vulnerable people.

Yet it is these qualities my research has revealed are most valued by our people.

The notion of “Emu Men” has emerged throughout my PhD.

Male emus are the primary carer for their chicks. The male partner will sit on the nest and the father rears the babies.

This notion of manhood and fatherhood – someone dedicated to his family, who has a primary responsibility to ensure the safety of his children and their passage through the world – appears to be deeply entwined in many of our peoples’ customs and cultures.

In Uncle Archie, we find the most profound sense of this alternate masculinity.

His songs will live on forever. But he also gifted us this alternate image of an Aboriginal man: someone soft, tender, loving, vulnerable, generous, resilient. Someone profoundly strong and with an inner wisdom, who sat on his nest and looked after his family and young people experiencing hardship.

It will take time to come to terms with this loss.

To his family we offer our hearts and hold you in our spirit.

This great songman gave our people a voice and a way to understand what has happened to us. He gave so much to a nation that treated him so badly.

As for me, like many others, Uncle Archie’s music and concerts has offered companionship through major life events. My wife and I danced to Love in the Morning on our wedding day.

And as for From Paradise, from the first moment I heard this song I thought he wrote it about my grandmother who was taken away and sent to Palm Island.

It is difficult to put words to this loss – Uncle Archie was always the one with the words.

Thank you for everything Uncle. May you soar with the eagles.

Aunty Ruby be happy to see you.
