Child sexual abuse material is rampant online, despite considerable efforts by big tech companies and governments to curb it. And according to reports, it has only become more prevalent during the COVID-19 pandemic.

This material is largely hosted on the anonymous part of the internet — the “darknet” – where perpetrators can share it with little fear of prosecution. There are currently a few platforms offering anonymous internet access, including i2p, FreeNet and Tor.

Tor is by far the largest and presents the biggest conundrum. The open-source network and browser grants users anonymity by encrypting their information and letting them escape tracking by internet service providers.

Online privacy advocates including Edward Snowden have championed the benefits of such platforms, claiming they protect free speech, freedom of thought and civil rights. But they have a dark side, too.

Tor’s perverted underworld

The Tor Project was initially developed by the US Navy to protect online intelligence communications, before its code was publicly released in 2002. The Tor Project’s developers have acknowledged the potential to misuse the service which, when combined with technologies such as untraceable cryptocurrency, can help hide criminals.

Explainer: what is the dark web?

Tor is an overlay network that exists “on top” of the internet and merges two technologies. The first is the onion service software. These are the websites, or “onion services”, hosted on the Tor network. These sites require an onion address and their servers’ physical locations are hidden from users.

The second is Tor’s privacy-maximising browser. It enables users to browse the internet anonymously by hiding their identity and location. While the Tor browser is needed to access onion services, it can also be used to browse the “surface” internet.

Accessing the Tor network is simple. And while search engine options are limited (there’s no Google), discovering onion services is simple, too. The BBC, New York Times, ProPublica, Facebook, the CIA and Pornhub all have a verified presence on Tor, to name a few.

Service dictionaries such as “The Hidden Wiki” list addresses on the network, allowing users to discover other (often illicit) services.

Child sex abuse material and abuse porn is prevalent

The number of onion services active on the Tor network is unknown, although the Tor Project estimates about 170,000 active addresses. The architecture of the network allows partial monitoring of the network traffic and a summary of which services are visited. Among the visited services, child sex abuse material is common.

Of the estimated 2.6 million users that use the Tor network daily, one study reported only 2% (52,000) of users accessed onion services. This suggests most users access the network to retain their online privacy, rather than use anonymous onion services.

That said, the same study found from a single data capture that about 80% of traffic to onion services was directed to services which did offer illegal porn, abuse images and/or child sex abuse material.

Another study estimated 53.4% of the 170,000 or so active onion domains contained legal content, suggesting 46.6% of services had content which was either illegal, or in a grey area.

Although scams make up a significant proportion of these services, cryptocurrency services, drug deals, malware, weapons, stolen credentials, counterfeit products and child sex abuse material also feature in this dark part of the internet.

Only about 7.5% of the child sex abuse material on the Tor network is estimated to be sold for a profit. The majority of those involved aren’t in it for money, so most of this material is simply swapped. That said, some services have started charging fees for content.

Several high-profile onion services hosting child sex abuse material have been shut down following extensive cross-jurisdictional law enforcement operations, including The Love Zone website in 2014, PlaypEn in 2015 and Child’s Play in 2017.

A recent effort led by German police, and involving others including Australian Federal Police, Europol and the FBI, resulted in the shutdown of the illegal website [Boystown](https://en.wikipedia.org/wiki/Boystown_(website) in May.

But one of the largest child sex abuse material forums on the internet (not just Tor) has evaded law enforcement (and activist) takedown attempts for a decade. As of last month it had 508,721 registered users. And since 2013 it has hosted over a million pictures and videos of child sex abuse material and abuse porn.

The paedophile (eroticisation of pre-pubescent children), haebephile (pubescent children) and ephebophile (adolescents) communities are among the early adopters of anonymous discussion forums on Tor. Forum members distribute media, support each other and exchange tips to avoid police detection and scams targeting them.

The WeProtect Alliance’s 2019 Global Threat Assessment report estimated there were more than 2.88 million users on ten forums dedicated to paedophilia and paraphilia interests operating via onion services.

Countermeasures

There are huge challenges for law enforcement trying to prosecute those who produce and/or distribute child sex abuse material online. Such criminal activity typically falls across multiple jurisdictions, making detection and prosecution difficult.

Undercover operations and novel online investigative techniques are essential. One example is targeted “hacks” which offer law enforcement back-door access to sites or forums hosting child sex abuse material.

Such operations are facilitated by cybercrime and transnational organised crime treaties which address child sex abuse material and the trafficking of women and children.

Given the volatile nature of many onion services, a focus on onion directories and forums may help with harm reduction. Little is known about child sex abuse material forums on Tor, or the extent to which they influence onion services hosting this material.

Apart from coordinating to avoid detection, forum users can also share information about police activity, rate onion service vendors, share sites and expose scams targeting them.

The monitoring of forums by outsiders can lead to actionable interventions, such as the successful profiling of active offenders. Some agencies have explored using undercover law enforcement officers, civil society, or NGO experts (such as from the WeProtect Global Alliance or ECPAT International) to promote self-regulation within these groups.

While there is a lack of research on this, reformed or recovering offenders can also provide counsel to others. Some sub-forums seek to offer education, encourage treatment and reduce harm — usually by focusing on the legal and health issues associated with consuming child sex abuse material, and ways to control urges and avoid stimuli.

Other contraband services also play a role. For instance, onion services dedicated to drug, malware or other illicit trading usually ban child sex abuse material that creeps in.

Why does the Tor network allow such abhorrent material to remain, despite extensive opposition — sometimes even from those within these groups? Surely those representing Tor have read complaints in the media, if not survivor reports about child sex abuse material.

Today’s Australian fathers are believed to be more “hands on” and engaged with their children than the stereotypical absent breadwinner of generations past.

However, our research exploring Australian fatherhood between 1919 and 2019 has found that while men’s family roles have changed, deep-rooted societal and cultural forces keep them from being the kind of fathers many of them would like to be.

The breadwinner of the early 1900s

Our research examined oral history interviews with (and about) fathers from diverse backgrounds, along with archival sources including letters, diaries and government files. Our goal was to better understand the experience of Australian fathering over the past 100 years.

We found a key factor shaping the history of Australian fatherhood has been the demands of paid work and the enduring power of the provider role — even in situations where dads are not the sole earners.

While the breadwinner father is hardly a uniquely Australian phenomenon, the ideal became institutionalised here in distinctive ways.

The 1907 Harvester Judgement, a landmark court ruling, established the principle that the male basic wage should support a wife and three children. This decision, which in turn ensured lower wages for women, remained the basis for setting Australia’s minimum wage until the 1970s.

Male breadwinner assumptions shaped not just the country’s wages but also welfare and tax policy, so that it simply made better financial sense for fathers to work and mothers to stay at home with the kids. This entrenched a gendered division of labour in family roles that would last for generations.

The Great Depression then made many fathers failed breadwinners. Geoffrey Ruggles, who was born in rural Victoria in 1924, recalled in an oral history interview that when his war-veteran father lost work, his mother was “forced to scrub other people’s washing”.

Humiliation fuelled marital discord and damaged Ruggles’ relationship with his father. He found an alternative father figure in his navy officer uncle:

[My uncle] had a lot of glamour about him […] an extrovert, a bright outgoing, merry man. A contrast to my father who was a sad sack. So Uncle Tom was a great fellow to be with, he gave me tools and helped me to start things like that, and fostered an idea of innovation – of doing what I wanted to do.

The sons of struggling Depression-era families often grew up determined to be good providers for their own families.

Many were also veterans who sought the stability of “traditional” family life. These men became the stereotypical, Holden-driving, breadwinner fathers of the “imagined fifties”, counterpart to the stereotypical 1950s housewife.

These stereotypes are not entirely wrong. The sole-breadwinner father is often assumed to be the historical norm, but in fact this family arrangement was broadly achievable for only a brief time between the early 1950s and 1970s. For the only time in Australian history, many working-class families could manage on one wage.

By the mid-1970s, however, recessions, deindustrialisation and the casualisation of the workforce shattered the economic security of the (male) “job for life”. At the same time, feminism and equal pay were mounting a new challenge to the male breadwinner stereotype.

Nurturing dads raise emotionally intelligent kids – helping make society more respectful and equitable

The “new man” of the late 20th century

History is so often circular. The sons of the postwar, breadwinner fathers wanted to do things differently from their dads, too.

In another oral history interview, Peter, a man born in Melbourne in 1956, recalled:

As a teenager in the 1970s […] most of the guys that I knew had lousy relationships with their dads. And I think that was really common […] a lot of them had been to war, they’d come home and their role was to build a family, you know, build a financial basis for it so they worked long hours and they just really didn’t seem to relate to their sons.

We all got on really well with each other’s mothers. But the fathers were very distant figures and it’s very different from today.

The social, cultural and economic transformations sweeping Australia from the mid-1970s brought new opportunities and expectations for fathers. Feminism and the growing numbers of working mums challenged traditional gender roles in families and contributed to the emergence of the popular ideal of the “new man” by the 1980s.

Fathers of this generation were more likely to be present at the births of their children, and to be physically and emotionally “present” dads.

The inevitable outcome of these changes, some assumed, would be a dual worker-carer model of family life in which mothers and fathers have more equal parenting roles.

The “modified breadwinner” family

Yet, today’s fathers still find their working lives to be a significant barrier to their ability to be active and engaged fathers.

Since the mid-1990s, the most common family formation has been the “modified breadwinner” model. Mothers typically return to work after having children, usually part-time, while the full-time working father earns the primary wage.

The fatherhood penalty: how parental leave policies perpetuate the gender gap (even in our ‘progressive’ universities)

Although fathers are caring for children slightly more than in the past, time use surveys confirm how much more time women spend doing childcare today compared to men. The unpaid labour of household and family management still largely falls on mothers, with dads “helping”, as homeschooling during COVID has laid bare.

Fathers interviewed in the late 1990s and early 2000s express a desire to be more involved, but are tied to paid work that limits the time and opportunity for parenting. Many speak of the stress of trying to meet expectations at work, as well as home, and some feel excluded from family life.

Peter, a man born in the mid-1950s in Victoria, recalls:

I was probably working pretty long hours and a lot of the duties were left up to my wife to do […] Even on the weekends, I found that if the kids had a choice of who they would go with, they tend to choose my wife anyway. I found that distressing quite often.

I never used to get home from work till 7:00-7:30. My job was to earn money, and the only time I did stuff around the house was on the weekend and for the kids.

The fathers who spend the most time with their children tend to be those living in less typical family types, including single and stay-at-home dads.

Gay male couples with kids are less detached from their children’s daily care than fathers in heterosexual couple families, perhaps because they are able to evade the “gender baggage” that influences men’s and women’s roles in families.

The parenting paradox

Today’s Australian fathers face a striking paradox. They are expected to be more “hands-on dads”, yet there’s been little systemic change in their working lives (including access to, and uptake of, parental leave and flexible work). There’s also been little change to gendered roles in family arrangements: a situation that, admittedly, many fathers have been happy to roll with.

Most fathers are still working long hours and many are concerned about how little time they have to be engaged fathers. Today’s dads may not view breadwinning as their raison d’être, but the breadwinner model of Australian fatherhood is not yet “history”.

The design and construction of new homes in Australia may leave residents vulnerable to heatwaves and local councils can do little to fix the situation, our new research has found.

Our study focused on the Jordan Springs development at Penrith in Western Sydney. We found the estate may not be fit to withstand future heatwaves, potentially putting residents at risk and leaving them dependent on increasingly expensive air conditioning.

Australians are already experiencing significant heatwaves. And the Intergovernmental Panel on Climate Change this month warned heatwaves will become even more frequent, intense and longer.

Rising house prices in Australia’s major cities are driving many people to more affordable housing estates on the city fringe. But without interventions from state governments and local councils, such estates may be unsustainable as heatwaves intensify.

Exacerbating hot temperatures

Jordan Springs is a ten-year-old planned housing estate located 7km from Penrith. As of the 2016 Census, the estate was home to 5,156 residents. It currently consists of 1,819 homes and it is forecast to grow to about 13,000 residents in 4,800 homes.

Our research involved:

• collecting secondary information about the area, including climate forecasts, regional growth forecasts and planning law
• conducting surveys and interviews with residents, government and council officials and scientific experts
• examining the estate’s physical exposure to heat through aerial imagery and ground cover analyses.

Inland suburbs are significantly hotter than those on the coast, due to the lack of cooling coastal breezes. That is true of Penrith, which lies 60km west of Sydney’s central business district. On average, Penrith experiences three times more days above 30℃ than the CBD.

Jordan Springs is compliant with building regulations and individual homes are compliant with NSW’s Building Sustainability Index (BASIX). However, we found the estate’s built environment exacerbates the region’s hot temperatures and exposes residents to higher indoor temperatures. This points to a need for better planning regulations and building design.

We suspect our findings may be true for other planned estate developments across New South Wales and Australia, but more research is needed to confirm this.

Houses for a warmer future are currently restricted by Australia’s building code

What we discovered

Homes in the estate are built close together, with minimum side and rear distances from adjoining properties of 1.8m and 6m respectively. This can prevent air flow and allow heat to accumulate during the day. The close proximity also reduces space for vegetation.

The estate’s streets are wide and buildings are low. This reduces shade and maximises exposure to the sun of roofs, roads and other hard surfaces.

Almost 59% of Jordan Springs is heat-trapping hard surface cover such as concrete and asphalt. This compares to just 10% combined tree and shrub cover. A lack of greenery can contribute to the accumulation of heat.

Houses, roofs, and surrounding surfaces (such as roads, walls and fences) are generally dark-coloured, which increases heat absorption. For example, dark roofs have been recorded as 20-30℃ hotter than light coloured roofs (see images below).

The NSW government last week recognised the problem dark roofs pose in hot weather, announcing light-coloured roofs will be mandatory in new homes in parts of southwest Sydney.

At Jordan Springs, we found some houses were poorly insulated and draughty. Yet many of these homes still attained a high BASIX star rating for energy efficiency.

The Conversation sought a response from the developer, Lend Lease. A company spokesperson said given the technical nature of the findings, it could not provide an adequate comment by deadline.

Buildings produce 25% of Australia’s emissions. What will it take to make them ‘green’ – and who’ll pay?

A persistent problem

During heatwaves, the built environment can exacerbate already dangerous conditions for humans. Many people turn on their air conditioners to beat the heat, increasing energy use and leading to higher electricity bills.

So why does this situation persist?

One councillor believes the profit imperative of developers is a factor, telling us:

the developers are only thinking about their shareholders and directors … I don’t believe that the developer is eco-friendly.

Meanwhile, a scientific expert said:

Today people don’t build double brick because of the cost […] they are about building fast and moving on and building more because of the profit they make […] everything must be cheap or else you can’t be fast.

In recent years there have been media reports of private certifiers signing off on buildings which do not meet planning guidelines. One local councillor told us this can result in homes that don’t perform well in hot weather.

And even if councils could enforce stricter rules, they risk losing interest from developers – and associated financial benefits. A frustrated council official said if one council had strict rules around housing developments and heat, and the neighbouring council did not, then:

developers are more likely to go there to build housing … It’s a tricky balance. We still want growth, and we want to work with developers, but we want to improve how we are doing things.

So where to now?

Clearly, many planned housing estates are not fit-for-purpose in our changing climate. But residents can take action to help their homes and estates stay cooler in hot weather.

Where possible, install heat-resistant features such as blinds, shades and awnings to increase passive cooling and reduce air conditioning dependence. Plant trees and shrubs in home gardens and encourage communities to engage in estate-wide greening initiatives.

Councils and developers should ensure prospective residents understand the benefits of light-coloured materials, passive design and urban green space. This will encourage them to make more informed decisions during the construction process.

But ultimately, the responsibility to ensure the heat-resilience of current and future housing rests with state governments and developers. While building new homes and returning profits is important, the well-being of citizens in a warmer world must be the paramount concern.

Australia is in the middle of its worst COVID-19 outbreak. Our hospital system is under strain. Vulnerable communities are being hit hard. And more than half the nation is locked down.

There is an understandable desire to know when we can reopen. But there is also an even more important need to know how we can reopen.

The national plan endorsed by the prime minister and state and territory leaders goes part of the way to answering this question.

It sets thresholds for the proportion of the 16-plus population vaccinated beyond which it says certain restrictions can be less common.

But it doesn’t talk much about the other things we will have to do.

How we reopen is as important as when

It’s the big gap in the national approach. And it needs to be filled. Now.

That is what OzSAGE aims to do. OzSAGE is an additional expert resource for governments and business, health, education, community and non-government agencies in Australia.

Inspired by the UK Independent SAGE (Independent Scientific Advisory Group for Emergencies), OzSAGE members have expertise in public health, infectious diseases, epidemiology, Aboriginal health, engineering, the built environment, occupational hygiene, behavioural and social science, multicultural engagement, communications, law, data science, public policy and economics.

Ventilation will become a priority

Our first piece of advice on how to best live with occasional outbreaks centres on ventilation and what we are calling vaccines-plus.

Ventilation (and filtration) is about providing safe air and limiting transmission in shared spaces. These include workplaces, health and aged care, schools, prisons, social venues and homes, especially where overcrowding is present. COVID is airborne, meaning prevention requires safe air.

Vaccines are essential to our pandemic exit strategy, but overseas experience shows current vaccines alone are not sufficient to fight the Delta variant.

“Plus” refers to testing, contact tracing, masks and other non-pharmaceutical strategies that will continue to be required in the medium term to fight Delta, and may need to be scaled up or down depending on severity of the epidemic.

Our first recommendations have been with politicians for a week.

They are released publicly this morning.

One of the things that made Australia’s 2020 pandemic response world-leading was that we acted early to keep the virus under control. This gave us options other countries did not have.

As we reopen we should ensure we do so safely enough to retain what economists call “option value” — the ability to adapt to changing circumstances.

Our approach should entail the following elements.

1. Living with occasional outbreaks rather than widespread disease

COVID-19 is here to stay, but we don’t have to resign ourselves to losing all the gains won in 2020. We should aim to control COVID-19 in the same way we control measles, which is even more contagious.

Right now that requires ventilation and “vaccines-plus” to manage outbreaks. But the level of innovation in vaccines is extraordinary.

When boosters or vaccines matched to variants are available, herd immunity ought to be possible using a smart and agile vaccine strategy.

2. Leaving no-one behind

Vaccine targets should be met for all, not only for the population as a whole but also for subgroups, recognising structural and social disadvantage.

These include all Aboriginal and Torres Strait Islander people, residents of remote and regional Australia, and other vulnerable high-risk and disadvantaged groups.

While vaccination is not available yet for all children, we recommend additional steps to protect them and make schools safe.

3. Protecting the health system

Australia has one of the best healthcare systems in the world. Despite this, urgent non-COVID care is already suffering in NSW.

We plan to outline a range of strategies essential to preventing the loss of health workers and protecting hospitals and their patients in cities and in regional areas.

Poorly ventilated schools are a super-spreader event waiting to happen. It may be as simple as opening windows

The best-laid plans to reopen will be disrupted if the capacity of the health system to deal with COVID and non-COVID care is exceeded by a surge.

I am proud to be part of an expert group that will provide independent, cross-disciplinary advice on how to open up safely.

What’s next?

Our advice will be informed by the best evidence, but will be practical. It will provide government, business, and community organisations with a series of tangible measures that can be taken to ensure we can reopen safely.

Nobody knows what 2022 will hold. But we need to ensure Australia is in a position to consolidate its successes and avoid repeating its recent mistakes.

Proper ventilation is a start. We will have more to say in coming weeks.

Australians have always loved photography exhibitions. They are consistently among the most well attended at our museums and galleries, and have formed an important part of our cultural landscape since the middle of the 19th century.

Our research reveals a fascinating history of encounters, spaces, and techniques of display — hidden in more conventional accounts that focus on famous photographers and iconic images.

Here are ten exhibitions that represent some key chapters in this history.

Ten photos that changed how we see human rights

1. J. W. Newland’s ‘Daguerrean Gallery’, Sydney, 1848

Visitors to Australia’s first photography exhibition in 1848 climbed the steps above a wine and spirits store in the centre of Sydney to the studio of J. W. Newland. He had just arrived with 200 daguerreotypes made during an almost three-year journey from New Orleans, thorough Central and South America, across the Pacific to New Zealand, and finally to Sydney.

In delicate images formed on polished silver plates ranging from the size of an iPad to an iPhone, visitors saw “views” of other great Pacific ports such as Peru’s Callao, “specimens” of various Indigenous people, and “likenesses” of celebrities they had only read about in newspapers. These included Queen Pomare IV of Tahiti who had famously become caught up in French and British colonial rivalry.

Visitors could also have their own portrait taken for the gallery, joining the other daguerreotypes Newland advertised as covering “two thirds of the globe”.

2. The Australian Intercolonial Exhibition, Melbourne, 1866

In 1866, where Victoria’s State Library now stands, two purpose-built, timber exhibition halls were filled with commodities from ten Australasian colonies for the first Intercolonial Exhibition. The hundreds of photographs crammed between the profusion of the displays were such an important component they attracted their own review from the now defunct Australian Monthly Magazine.

This “wanderer amongst the photographic views” thought they exhibited “the high standard of taste to which we, as inhabitants of new colonies, have arrived”. Like the pyramidal “trophies” of canned foods and confectionery placed throughout the exhibition spaces, the photographs visualised and quantified colonial prosperity.

Scale and spectacle were everything. Many views of the new colonial buildings were contact printed from glass plate negatives 25 x 30 cm in size, and one multi-panelled panorama of Sydney stretched over a metre in length. Viewers could peer into the binocular lenses of a stereoscope, which enabled them to see a number of paired images taken from slightly different angles as a sequence of 3D views of Hobart.

3. Harold Cazneaux’s ‘One Man Show’, Photographic Society of New South Wales, Sydney, 1909

At the turn of the 19th century, Australian photography was transformed by the self-consciously artistic style of Pictorialism. In 1909, one of its emergent figures, Harold Cazneaux, held the first solo show by an individual Australian photographer.

Its 26 portraits, landscapes, seascapes, harbour scenes and “picturesque city corners” showed what “any energetic cameraist can secure in his lunch hour, if he is gifted with the ‘seeing eye’.”

Cazneaux proudly documented the tasteful installation of his show in the Sydney rooms of the Photographic Society of New South Wales. Each print was individually mounted behind a wide cardboard mat in an elegant frame and numbered, referring to a catalogue on a table beneath a vase of flowers. Cazneaux had set the template for thousands of photographers’ shows to come.

4. Wolfgang Sievers and Helmut Newton’s New Visions in Photography, Federal Hotel, Melbourne, 1953

Staged over five days at the Federal Hotel on Melbourne’s Collins Street in 1953, Wolfgang Sievers and Helmut Newton declared the bold aim of New Visions in Photography in an introductory wall panel. It was “to demonstrate … the potential of industrial and fashion photography as a means of better promotion and bigger sales”.

The two German émigrés embodied a dramatically new approach to the photograph. Sievers’ industrial and architectural studies and Newton’s fashion images both exploited radical vantage points and close-ups to produce bold, graphic compositions in sharp, high contrast black and white — reflecting Australia’s emergence as a modern nation.

The magazine-like display matched the formal qualities of the photographs. Instead of framed images in a row, enlarged unframed photographs were presented on white pegboard and suspended in the air by fine thread, sometimes at radical angles.

This dramatic sculpting of space in the old hotel underscored Sievers and Newton’s belief in photography’s potential to make the world anew.

5. Urban Woman, Melbourne Town Hall, 1963

Urban Woman was the most ambitious and accessible exhibition by a collective of Melbourne-based amateur photographers including Albert Brown, George Bell, Roy McDonald and John Crook who called themselves Group M. Earnest teachers and chemists, they were inspired by the tradition of social documentary.

Urban Woman comprised over 200 mostly candid, long, focal length images by 13 photographers (all male), selected by designer Max Forbes. Inspired by the photographers’ observation of the “loneliness” of young suburban mothers, they aimed “to confront reality with an unprejudiced eye”.

The fact that an exhibition about women was made exclusively by men went unnoticed in the significant press coverage it attracted.

Conceived as a direct response to the international blockbuster The Family of Man, which toured to Australia in 1959, Urban Woman appealed to similar humanist sentiment. Its design featured purpose-built wooden structures to display huge, unframed prints, with subjects arranged from youth to old age.

6. Frontiers, National Gallery of Victoria, 1971

The National Gallery of Victoria became the first Australian gallery to establish a department of photography in 1967, despite opposition from some trustees (one of whom referred to photography as a “cheat’s way of doing a painting”). At the time, it was one of only a handful of such departments in the world.

Frontiers featured the experimental and abstract photography of John Cato, Peter Medlen, Stanislaus Ostoja-Kotkowski, Mark Strizic and John Wilkins. All-male photography exhibitions remained common until the pioneering exhibitions of feminist photographers such as Sue Ford and Carol Jerrems in the mid-1970s.

The work in Frontiers was self-consciously contemporary, even psychedelic. Cato’s environmental protest work comprised 52 prints installed on crimson screens with strobe lighting. Ostoja-Kotkowski’s light transparencies, formed by laser beams and infra-red, were backlit from spotlights mounted on the ceiling. Strizic presented a 10-metre colour mural (later destroyed due to chronic fading).

7. William Yang, Sydneyphiles, Australian Centre for Photography, 1977

In 1977, William Yang used the walls of the new Australian Centre for Photography for a diaristic exhibition, Sydneyphiles. This was Yang’s first exhibition, in which his small scale colour and black and white photographs of Sydney’s gay community and its art, fashion and socialite scenes were hung closely alongside and above each other to cover the walls like a giant personal scrapbook.

Sydneyphiles is significant for reasons beyond its controversial sexual content. It was an early example of the Centre moving beyond a more conventional framed black and white modernist tradition.

It is likely the first exhibition by an Asian-Australian photographer, and it included its community as part of the event (the press release notes Yang “invited many of the subjects of his photography” to his exhibition). Yang later said the exhibition “launched me as a photographer”.

8. National Aboriginal and Islander Photographers Exhibition, Aboriginal Artists Gallery, Sydney, 1986

The first exhibition in which Aboriginal people had control over their own photographs took place in 1986 during what is now known as NAIDOC week. On the raw brick walls of Sydney’s Aboriginal Artists Gallery, ten Indigenous photographers hung their exhibition.

They included Mervyn Bishop, Australia’s first Aboriginal press photographer, and others such as Brenda L. Croft, Michael Riley and Tracey Moffatt, who went on to become important figures in Australian art.

The show featured photographs that later became touchstones, such as Moffatt’s portrait of actor David Gulpilil relaxing at Bondi beach in board shorts and face paint.

It was an immediate success, as Moffatt ruefully commented: “To be honest, we got the kind of publicity which makes me want to vomit; e.g. ‘they’re Aborigines, they’re articulate, and gee whizz, they take good pictures’ sort of stuff. I guess I shouldn’t complain because we got a lot of people coming through looking at the show and buying work, which is what we do like!”

9. Photography Is Dead! Long Live Photography!, Museum of Contemporary Art, Sydney, 1996

In 1996, as the medium was being transformed by the impact of digital photography, the Museum of Contemporary Art mounted Photography Is Dead! Long Live Photography! For curator Linda Michael its 32 exhibitors were “artists using photography”, not photographers per se. They saw photographs not as transparent windows onto the world, but as a material within themselves.

Some large unframed prints were suspended to curl delicately out from the wall, others were bonded onto aluminium for an industrial look; some were expressionistically cut up, others were physically sculpted.

Some — such as Jane Eisemann’s surrealist imagery and Patricia Piccinini’s glossy advertising style portraits of a celebrity starlet holding a genetically modified pet — were digitally produced, with computer manipulation an intrinsic part of their meaning.

10. Hoda Afshar’s Remain, The Substation, Melbourne, 2019

Photographs have long appeared in public space in the form of corporate messaging. They can be projections or billboards. To offer different messages, Tehran-born, Melbourne-based artist Hoda Afshar is one of many who have taken advantage of inexpensive, large-scale printing to give voice to the experiences of marginalised people.

In 2019 Afshar presented her striking, collaboratively-produced portraits of asylum seekers incarcerated by the Australian Government on Manus Island on 2.4-metre-high billboards along the train line that skirts The Substation in the western Melbourne suburb of Newport.

The Christ-like image of the Iranian journalist Behrouz Boochani was already becoming iconic, having won a major photography prize and circulated in newspapers and Afshar’s Instagram account (arguably the most important site for photography today).

But the public display amplified the political potency of her ghostly black-and-white portraits to new audiences. As she has said, “When you make a socially and politically engaged work, the intention is to communicate with the people”.

These moments are drawn from our book Installation View: Photography Exhibitions in Australia (1848-2020) published by Perimeter Editions in 2021.

In the Orwellian world of the pandemic, Victoria Premier Daniel Andrews’s raising of the white flag on “COVID zero” was greeted positively by the Morrison government and with relief by many among the public who are at the end of their tether.

We’ve now officially moved into a new stage. As federal Health Minister Greg Hunt said on Thursday, “the pandemic has become endemic”.

In accepting Victoria couldn’t get back near zero, Andrews was following NSW Premier Gladys Berejiklian, who lost control of the virus, with daily new cases in that state now running well above a thousand and rising.

Only weeks ago there were hopes of suppressing the outbreaks in both states. When it was becoming obvious NSW was failing, Berejiklian was criticised for not locking down early and hard enough. Andrews went hard immediately – and failed too.

“Living with COVID is a reality – it’s not an option,” Berejiklian said on Thursday, sending the blunt message to premiers still set on COVID-minimalism that they’d have to accept the Delta world.

As they will. But not for some time, if they can help it.

Watching Australia’s third wave escalate, the Labor states of Western Australia and Queensland are dug in, trenchantly and vociferously, behind their efforts to keep cases out. The brawling between them and the Morrison government took on an even sharper edge this week.

In contrast, Morrison praised the Liberal premiers of South Australia and Tasmania, who are also pursuing COVID zero, but keeping their heads down.

Australia’s federation is now more fractured than at any time during this crisis, in a toxic mix of policy differences and politics, exacerbated by the approaching federal election.

WA’s Mark McGowan must be concerned as to how he’ll eventually reintegrate his state into the rest of the country, which he accepts must happen at some point. With WA vaccination levels lagging, he’s not tying himself down but says he’ll set a date when “the time is right” (assuming he’s not mugged by a runaway outbreak). He wants to ensure vulnerable sections of the population are fully protected. The state’s isolation and insulation help him.

Economic imperatives for WA’s opening will strengthen, but McGowan can usually outplay the federal government on the politics.

Last year Scott Morrison had to make an embarrassing withdrawal from the Clive Palmer challenge (subsequently lost) to the WA border closure, after it became clear local public opinion was strongly on the state government’s side.

This week federal Attorney-General Michaelia Cash, who’s from WA, mused about how an action could be more successful in the changed circumstances of a vaccinated population (not that the federal government is planning to launch a case).

McGowan seized the baseball bat. “West Australians don’t want me to bring [the border] down now, to give in to this sort of crazy bullying by the federal government, and infect our population, lose jobs and shut down part of our economy, including the mining industry,” he said.

This highlights, incidentally, a point often overlooked in the heated political rows. Talk about “opening” WA and Queensland refers to opening borders. Internally, these states are “open” – unlike the shuttered NSW and Victoria.

McGowan is usually careful to avoid overreach. In contrast, Queensland Premier Annastacia Palaszczuk went over the top when she defended her closed border with an emotive claim about the danger to young children.

“You open up this state and you let the virus in here, and every child under 12 is vulnerable, every single child,” she told state parliament on Wednesday. These children were “vulnerable because they are the unvaccinated”.

The federal government, and other critics, retorted that while young children caught the virus, very few got a severe illness, and they’ve not so far been vaccinated in other countries (although vaccination is being trialled in the US).

In the border wars, it’s worth remembering the big border decisions – about reopening Australia to the world – rest with the federal government.

There are multiple fronts – not just Australians travelling abroad and returning home, but also the admission of foreign tourists, students, workers to fill serious skill shortages, and migrants. The relaxation won’t be done all at once; even so it will be challenging – for example, needing home quarantine arrangements as well as vaccination requirements.

The government’s COVID strategy is built around the national cabinet “plan”, underpinned by the Doherty Institute’s modelling, and buttressed with the catchword “hope” and the promise of a great Christmas.

But grim realities will accompany the transition.

NSW is likely to reach 3,000-4,000 daily new cases this month, while Victoria is expected to rise above 1,000 daily. In NSW, the state government is bracing for the month of October to be very bad, in hospitalisations and deaths.

More generally, the Australian Medical Association wrote to Morrison this week warning of a looming crisis in the public hospital system.

“As it stands, our hospital system is not ready to cope with an easing of restrictions, even with increased vaccination rates,” the letter from AMA president Omar Khorshid said. “To prepare we must develop a detailed understanding of our current hospital capacity and model the impact of ‘living with COVID-19’, with the associated caseload increase.”

The AMA suggested a vaccination rate of higher than 80% of the adult population was likely to be required, “given the existing constraints on hospital capacity and staffing”.

With Friday’s national cabinet receiving a report on the health system and its workforce, the government appears inclined to regard the AMA pitch as part of its periodic appeal for more hospital funding.

But from what we’ve seen in NSW, with some hospitals coming under acute pressure, and evidence the WA system is already inadequate, hospitals are clearly a potential weak point in our defences as COVID cases rise quickly after restrictions are eased in coming months.

We know the Morrison government is now totally focused on getting life back to some normality. It stresses this will be done “safely”.

In fact, it is less a matter of opening “safely” than minimising the risks inevitable in opening. That goes beyond the state of the health system to include issues such as sub-groups in the population who might not be adequately vaccinated when the general community levels of 70% and 80% are reached. Dealing with the risks will demand more nuance than “the plan” seems to provide.

The government is banking on the attention of people – who are now deeply frustrated if they live in NSW or Victoria – shifting decisively off the health issues once life is freer. That, however, will depend on effective management of an unpredictable transition.

This week the World Health Organization named a new “variant of interest” of the coronavirus, called the Mu variant. It was first found in Colombia in January 2021, and has been found in about 39 countries so far.

Mu has changes, called mutations, which mean it might be able to evade some of the protection we get from COVID vaccines.

But one reassuring element is that, despite being around since January 2021, it doesn’t seem to be outcompeting Delta, the dominant variant across most of the world.

If Mu was truly a really bad variant, we would have expected to have started to see indications of this, and we haven’t yet.

Coronavirus variants have new names: we can finally stop stigmatising countries

What’s a variant of interest?

An impressive element of our COVID response has been frequent genomic sequencing, which we haven’t done before on this scale. This tracks and maps the evolution of the virus in real time, as it adapts and mutates.

Some mutations will be detrimental to the virus, but some will be beneficial, allowing it to spread better, escape the protection offered by vaccines or even evade COVID tests.

If there are changes to the virus that mean it looks like it has the potential to do more harm, then we might designate it a “variant of interest”.

Mu has mutations that might confer some of these properties, but evidence is still emerging.

The four other variants of interest are Eta, Iota, Kappa and Lambda.

If there’s good evidence Mu is more serious and beginning to overtake other variants such as Delta, it might be upgraded to a “variant of concern”. The four variants of concern are Alpha, Beta, Gamma and Delta.

Can it escape vaccines?

Most COVID vaccines target the “spike protein” of the virus, which it uses to enter our cells. Our vaccines expose our bodies to a part of the virus, commonly the spike protein, so our immune system can learn to fight the virus off if it encounters it.

If a variant has significant changes in the spike protein, this may decrease the effectiveness of our vaccines.

Read more:
There’s no need to panic about the new C.1.2 variant found in South Africa, according to a virologist

The WHO said preliminary evidence suggests the Mu variant could partially evade the antibodies we get from vaccination.

But because this data is from lab studies, we can’t be sure how the variant will actually play out in the population.

We need more research to be certain about how it behaves in humans, and work on this is ongoing.

The good news is our vaccines currently protect well against symptomatic infection and severe disease from all variants of the virus so far.

Vaccines may not protect forever

There’s a high probability a new variant will arise one day that can significantly escape the protection offered by our vaccines, which are based on the original strain of the virus. We would call this an “escape variant”.

It’s hard to know if and when this would happen, but rampant community transmission of the virus increases the chances of such a variant emerging.

Read more:
How will Delta evolve? Here’s what the theory tells us

However, the leading COVID vaccine manufacturers are well prepared if this eventuates. Some are already developing vaccines for new variants, such as Delta.

If we did discover an escape variant, some vaccine manufacturers could alter their existing vaccines to match the new variant, possibly within 6-8 weeks. Medical regulators around the world would likely accelerate the approval process to make this possible. Certain studies would be required but these could be done quickly, so long as the new vaccine had basically the same properties as the existing vaccine.

It’s possible we could see a variant overtake Delta in terms of infectiousness eventually. Scientists think it’s at least 50% more infectious than the Alpha variant, which was about 50% more infectious than the original strain.

Evolutionary theory predicts the virus may become more transmissible over time, but less severe, as a virus wants to spread as much as possible and doesn’t want to kill its host before it can do so. But this may not necessarily be how SARS-CoV-2 plays out, and realistically we’re still in the early days of this virus.

The best way of combating variants is to get as many people vaccinated as possible, so there are fewer susceptible hosts for the virus to reproduce and mutate.

Read more:
New COVID variants have changed the game, and vaccines will not be enough. We need global ‘maximum suppression’

There is a risk that once we have the majority of the world vaccinated, vaccines may place “selective pressure” on the virus to evolve to escape vaccines. But the benefits of having more people vaccinated outweighs this risk.

I don’t think it’s time to be concerned about Mu yet. If it became a “variant of concern”, then we might be more worried. But we have some amazing tools to fight this virus, including many successful vaccines — the majority of which can be adapted quickly to new variants.

It’s likely we’ll have regular booster shots to protect us against variants in the future.

Nationals MP George Christensen recently copped condemnation from federal parliament for spreading misinformation about COVID-19.

The member for the central Queensland seat of Dawson falsely claimed masks and lockdowns were ineffective against the spread of COVID, demanding governments “open society back up” to “restore our freedoms [and] end this madness”. In a rare move, both Labor and the government backed the motion against him.

The comments were outrageous, but not surprising. Christensen, who has been in parliament since 2010, has a long history of courting controversy, including comments on Muslim immigrants and global warming.

Why do people listen to him? Where does his power base come from?

Democratically elected, so…

Understanding why Christensen can make such statements — and why the news media report them — is simple: as a democratically elected MP, he is entitled to air even the most egregious views under parliamentary privilege.

Of course, the parliament is equally entitled to condemn him. And the more novel his views, and the more conflict they produce, the more likely they are to be reported.

What is more difficult to explain, however, is how and why maverick politicians succeed in a liberal democracy like Australia, where the confines of political discourse have traditionally been quite narrow.

Unlike many European polities, Australian politics have never really entertained hard socialism on the left or ultra-conservatism on the right, at least until the rise of Pauline Hanson’s One Nation in the late 1990s.

The maverick tradition in Australia

Yet mavericks have existed since the earliest days of Australian politics.

Before the evolution of the modern party system 130 years ago, rogues were common in legislatures free from party constraints. Today, given the major parties’ discipline over their MPs — most of whom boast frontbench ambitions — and an aggressive Fourth Estate, political mavericks are much rarer.

Read more:
Twenty years on, One Nation is still chaotic, controversial and influential

And those who fail to toe the party line are often forced out. Pauline Hanson, Bob Katter, Clive Palmer, Fraser Anning (Queensland appears to be a natural home to mavericks) are just a few examples of those who left established parties to lead their own, self-titled brigades.

Other mavericks include Graeme Campbell (Western Australia), Jacqui Lambie (Tasmania) and Fred Nile, Mark Latham and Craig Kelly (NSW).

While overwhelmingly from conservative ranks, mavericks have come from the centre, such as South Australia’s Nick Xenophon. They have also come from the hard left, in the case of Queensland’s Fred Paterson, Australia’s only Communist Party MP, elected to a central Queensland seat in the 1940s.

What is it about Queensland?

But what is it about Queensland regional voters and their predilection for mavericks?

The answer lies in understanding Queensland’s unique political culture – steeped in a populism that vilifies “elites” and “outsiders”. This itself built upon five pillars:

1. a reverence for strong, opinionated leaders
2. a demand for regional services across Australia’s most decentralised mainland state
3. a demand for local infrastructure
4. a preference for political pragmatism (“common sense” solutions to complex problems)
5. a Queensland chauvinism that encourages locals to feel superior to other Australians.

In a decentralised state overwhelmingly dependent on primary industries, where regional voters boast significantly higher rates of Christian identity and lower rates of higher education and multiculturalism, it’s perhaps unsurprising regional Queensland has long been shaped by frontier politics.

And any regional MP hoping to maintain electoral support must pander at least to some of these elements.

Christensen, for example, has previously called for a ban on the burqa and Muslim immigration from “radicalised” countries. In 2016, he floated the return of the death penalty. In 2014, the MP labelled environmentalists “terrorists” and, in a statement he later regretted, described the “Safe Schools” program as paedophile “grooming”.

Yet Christensen also supported a banking royal commission when his Coalition colleagues would not. And while his pandemic libertarianism – rooted in Donald Trump’s Republicanism – is a new development on the Australian hard right, it’s hardly surprising it finds a ready audience among regional Queenslanders, already suspicious of capital city power.

Christensen’s success

The formula appears to work. The seat of Dawson, based on sugar farming districts surrounding Mackay, has been in Country/ National/Liberal-National party hands for all but 12 of its 72-year history. But over the past decade, Christensen has turned a thin after-preference margin of 2.4% into a safe 14.6% buffer.

However, the Christensen style has come at a cost. In sating the appetite of local voters, the MP has inevitably angered metropolitan colleagues and, therefore, blocked any chance of promotion.

Interestingly, returned Nationals’ leader Barnaby Joyce, himself something of a maverick, refuses to rebuke his MP — Joyce insists it’s worse than useless to “prod the [Christensen] bear”. Given the Morrison government’s razor-thin majority, an unwanted by election could plunge the Coalition into crisis.

In April, Christensen stunned observers when he announced his retirement at the next federal election. On Sunday, Whitsunday Regional Council Mayor Andrew Willcox was preselected as the Liberal National Party’s candidate for Dawson. Coal miner Shane Hamilton will contest the election for Labor.

Christensen’s successor won’t have to mirror him to hold the seat, but engaging in at least some of his populist behaviour will go far in building support over the longer term.

In choosing the timing of his own departure from a safe seat at age just 43, it seems Christensen remains a maverick to the very end.

Westmead Hospital in Sydney’s west says it has treated a patient who overdosed after taking the drug ivermectin, an unproven and potentially dangerous treatment for COVID-19.

The person went to hospital seeking treatment for diarrhoea and vomiting side-effects, after taking the drug, which is usually used to treat parasites. The person had ordered this and other unproven COVID “cures” online.

While the patient did not die, health authorities are concerned at the number of people taking ivermectin, and warn against it for anyone else who may have COVID symptoms or has been diagnosed with the virus.

Other known ivermectin side-effects range from mild to the life-threatening, including seizures and coma.

Why are people taking it?

Ever since researchers showed ivermectin could kill SARS-CoV-2 (the virus that causes COVID-19) in the laboratory, there has been interest in whether the drug would also work to kill the virus in the human body.

So far, there is no clinical evidence it works to treat or prevent COVID-19. And there is widespread consensus people should not take ivermectin at home for COVID-19.

Organisations that recommend against it include: the World Health Organization, Australia’s National COVID-19 Clinical Evidence Taskforce and NPS Medicinewise, the United State’s Food and Drug Administration, and the Cochrane Library.

Read more:
A major ivermectin study has been withdrawn, so what now for the controversial drug?

How are people getting hold of it?

Despite this, community pharmacists have reported increased demand for ivermectin, with people seeking the drug as a possible COVID treatment.

In Australia, ivermectin is approved to treat parasite infections in humans. It’s also widely used in veterinary medicine to treat and prevent parasite infections.

However, as a prescription-only human medicine (known as schedule 4), you can only access ivermectin legally in Australia after approval from a doctor.

This is because, like all medicines, ivermectin is not 100% safe. It does have possible harmful side-effects and a doctor’s judgement is necessary to decide if ivermectin is safe and appropriate for each patient.

So ivermectin is currently only recommended to treat and prevent COVID-19 when used as part of a clinical trial, where patients can be more safely selected and carefully monitored.

As well as more patients presenting to pharmacies with scripts, the Therapeutic Goods Administration warns about the danger of importing ivermectin products of unknown quality, bought over the internet.

This is risky because products may not contain the stated drug, may contain dangerous contaminants or much more of the drug than thought, which may result in an overdose.

Of most concern are reports from Australia and overseas of people buying and taking ivermectin products intended for animal use. People may be resorting to these types of products where they have been unable to access a script for human formulations of ivermectin.

What does it do to your body?

We know very little about what the drug does to humans, and the little we do know mostly comes from its use in animals.

When taken at the recommended dose, the drug is generally well tolerated. But ivermectin is known to cause mild side-effects such as diarrhoea, nausea, dizziness and sleepiness. Less common, but serious, side-effects include severe skin rashes and effects on the nervous system (causing tremor, confusion and drowsiness).

In higher doses, and overdose cases, these side-effects can be more severe. These include low blood pressure, problems with balance, seizures, liver injury, and it can even induce comas.

Coronavirus misinformation is a global issue, but which myth you fall for likely depends on where you live

The take-home message

The public is understandably interested in medicines to treat and prevent COVID-19. However, misinformation about ivermectin and others continues to circulate.

COVID-19 vaccination remains the best way to reduce the risk of serious illness and death from COVID-19. Australia’s National COVID-19 Clinical Evidence Taskforce provides the most up-to-date information about COVID-19 treatments and is a reliable source of information as new knowledge emerges.

If you or a family member take ivermectin and have strong side-effects you should seek medical advice. Call the Poisons Information Centre on 131 126. For life-threatening symptoms, call 000 for an ambulance.

Am I not pretty enough? This article is part of The Conversation’s new series introducing you to Australia’s unloved animals that need our help.

For many people, the term “wallaby” may describe a single species, or rather just a small kangaroo. So you may be surprised to learn there are actually more than 50 known species of wallaby in Australia.

The parma wallaby (Macropus parma) is one of Australia’s smallest. It’s no larger than a house cat, with a body length up to 55 centimetres and a tail about the same length again. It has thick, brownish-grey fur, and a defining white moustache.

But this is about as much as can be said for its appearance, as even its moustache is common to many other wallaby species, such as the yellow-footed rock-wallaby.

Here, we aim to defend the voiceless. The parma wallaby’s failure to charm with either its looks or charisma has condemned it to obscurity by the general public and wildlife researchers alike, potentially dooming it to extinction.

The parma’s resurrection

So overlooked is the parma wallaby that for more than 30 years, it was presumed extinct until 1966, when a feral population was discovered on Kawau Island, New Zealand.

The species was introduced there a century earlier by former Prime Minister of New Zealand, Sir George Grey, who’s zoological interests led to Kawau becoming home to a menagerie of exotic animals.

This sudden rediscovery resurrected the parma from the pages of natural history books, prompting a reintroduction program to re-establish the Kawau Island population in Australia. This occurred on two occasions, once on Pulbah Island in Lake Macquarie, and near Robertson, NSW. But both attempts were considered abject failures, with all reintroduced, marked individuals found dead, mostly due to predation by dogs and foxes.

Despite this unsuccessful program, the sudden spotlight on the species led to its rediscovery on the mainland in 1972 near Gosford, NSW. Soon after, a state-wide parma survey was conducted.

An elusive species

But since then, its ecology has largely gone unstudied and, once again, the parma has faded to obscurity.

The IUCN Red List — the pre-eminent assessment of the conservation status of the world’s biodiversity — has relied on a guestimate of population size, placing it at under 10,000 individuals.

Despite little monitoring the species is still considered only “near threatened” on the Red List, but events like the Black Summer bushfires may have significantly reduced its population.

As a result of its cryptic nature and very recent rediscovery in the wild, there is scarce known about the ecology of the parma wallaby. We don’t even know the exact origins of its name.

We do know its preferred habitat is moist eucalyptus forest with thick, shrubby understory. It shelters there during the day, often with nearby grassy areas as, at night, they typically feed on grass and herbs. They’re also found in rainforest margins and drier eucalypt forest, but to a lesser extent.

The parma wallaby is under threat

We also know the parma wallaby’s range is in decline and has been since European colonisation.

The species once occurred from southern Queensland to the Bega area in the southeast of NSW. Now, its range is confined to the coast and ranges of central and northern NSW. It’s patchily distributed throughout cool, high-altitude forests along the Great Dividing Range.

It weighs around 5 kilograms, placing it in the critical weight range category. This means it’s vulnerable to feral predators, such as dogs, cats and foxes.

Another major threat facing parma wallabies is habitat destruction from catastrophic bushfires.

The 2019-2020 Black Summer bushfires killed, injured or displaced an estimated three billion animals. Over half (55%) of the parma’s key habitat was severely burned. Coupled with the loss of those that would have perished in the flames, the species is now considered vulnerable in NSW.

Saving the parma

The recent bushfire Royal Commission raised the issue that Australia doesn’t have a comprehensive, central source of information about its native flora and fauna. This is especially urgent, given seemingly “drab” species like the parma wallaby that have gone unnoticed for too long.

All species rely on interactions with a plethora of other species to survive in a complex system from which humans are not exempt. But with so little known about these interconnected relationships, we don’t know what the broader impacts to the ecosystem would be if one species disappeared.

3 billion animals were in the bushfires’ path. Here’s what the royal commission said (and should’ve said) about them

Imagine a Jenga tower where each species is a wooden block. You can never really be certain which block you remove will cause the tower to collapse. Australia has an appalling extinction record, and we can’t afford to be playing Jenga with our biodiversity — whether it’s a boring bird, an ugly fish or just another wallaby.

Our ongoing research aims to help fill this conservation gap. We focus on a range of conservation actions the parma wallaby needs immediately.

These include carrying out field surveys to gauge the extent of their survival, and identifying the places that need refuge vegetation recovery. Refuge patches of bushland are important because they provide parma wallabies escape routes and places to hide, helping protect them from predation.

But you can help, too

Given the breadth of catastrophic fires is expected to increase under climate change, we can all help threatened species like the parma wallaby bounce back.

Come bushfire season, you can reduce the fire risk around your home by clearing anything that could fuel a fire — long grass, weeds and leaves on the ground and in guttering.

The parma wallaby, like many other little mammals, is vulnerable to introduced predators, especially cats. By keeping your cat indoors, you could be sparing the lives of 186 animals per year.

You can urge your politicians to value Australia’s unique and precious biodiversity. They are the ones who will ultimately determine whether our threatened species survive or go extinct.

Finally, you can volunteer. There are many volunteer-based conservation projects all over Australia, run by government agencies, charities, and universities.

With the ongoing pandemic travel restrictions, there’s no better time to experience the rich biodiversity this country has to offer, and discover less celebrated, but still fascinating, species like the parma wallaby.

The saga over subscription-based social media platform OnlyFans, which announced it would ban sexually explicit content only to reverse that decision a week later, has highlighted just how quickly such a platform can move the goalposts for those relying on it for an income.

Yes, the most successful “content creators” on OnlyFans can reportedly make more than US$100,000 a month. But they are the minority. Most barely make enough to justify the hustle, with the median income estimated to be US$180 a month.

Strip away the sexy marketing and what you have is just another digital platform facilitating another form of gig work, substantially no different to ride-share drivers or food-delivery couriers.

The increase in popularity of OnlyFans during the COVID-19 pandemic is mirrored by the growth of the gig economy more generally. With the pandemic hitting other forms of part-time and casual work, the attraction of the income-earning activities provided by digital platforms has increased.

Some of these activities outside of the traditional, long-term employer-employee relationship may even appear desirable, offering flexibility as child care and other demands have increased during lockdowns.

Though precise estimates are complicated by differences in definitions of work and the way statistics are counted, the data suggests at least 10% of the labour force in industrialised economies now rely primarily on gig work for their income. They may be called freelancers, independent contractors, temporary workers or consultants. More than a quarter of the workforce participates in the gig economy in some capacity.

Gig work is rightly controversial. It continues to be accused of driving inequities, exploitation and issues around workplace and occupational health safety. While there have been a few significant legal wins this year for some gig workers over employment status and rights, platforms still largely have the whip hand.

Shifting risks

Key to platforms’ power is how they avoid responsibilities and transfer risks to gig workers, by positioning themselves legally as intermediaries between customer and service provider.

This is achieved via the terms and conditions users agree to when they sign up. These terms and conditions can be changed at any time. While users are generally given notice, they are often unaware of changes because they don’t bother to read notifications before agreeing to updated terms.

In the case of OnlyFans, its “standard contract” gives subscribers permission to access content produced by a creator, and also implicitly obligates a creator to produce and provide content over time. The contract is just over 1,500 words — theoretically short enough to read, though it’s likely few do so entirely.

The contract does permit for the expiry of the licence where the creator removes content. It also includes a “no guarantees” clause that mostly protects the creator with regard to the removal or unavailability of content. These clauses superficially seem to give creators some protection from disgruntled fans. But in reality they are a trap for the unwary.

If things go wrong, consumer protection laws generally give customers rights that create liabilities for creators. For example, under Australian Consumer Law a court could strike out the “no guarantees” clause in the OnlyFans standard contract, making creators liable for non-delivery to fans.

Had OnlyFans banned sexually explicit content, subscribers could well have have been entitled to demand their money back from content creators. The platform would not have been liable.

Future challenges

The OnlyFans case thus highlights the precarity of gig work, and some interesting legal, social and governance challenges for the future.

2021 has delivered some landmark court rulings in Britain, the Netherlands and Australia rolling back the ability digital platforms such as Uber and Deliveroo to dictate the terms by which they engage and pay drivers and riders.

But these were limited wins, not applicable to all gig workers even in those jurisdictions. There is still more work to be done.

We all know the birds and the bees are important for pollination, and we often notice them in gardens and parks. But what about flies?

Flies are the second most common type of pollinator, so perhaps we should all be taught about the bees, the flies and then the birds. While we know animals may see colour differently, little was known about how fly pollination shapes the types of flowers we can find in nature.

In our new study we address this gap in our knowledge by evaluating how important fly pollinators sense and use colour, and how fly pollinated flowers have evolved colour signals.

The way we see influences what we choose

We know that different humans often have preferences for certain colours, and in a similar way bees prefer blue hues.

Our colleague Lea Hannah has observed that hoverflies (Eristalis tenax) are much better at distinguishing between different shades of yellow than between different blues. Other research has also reported hoverflies have innate responses to yellow colours.

The mystery of the blue flower: nature’s rare colour owes its existence to bee vision

Many flowering plants depend on attracting pollinators to reproduce, so the appearance of their flowers has evolved to cater to the preferences of the pollinators. We wanted to find out what this might mean for how different insects like bees or flies shape flower colours in a complex natural environment where both types of insect are present.

The Australian case study

Australia is a natural laboratory for understanding flower evolution due to its geological isolation. On the mainland Australian continent, flowers have predominately evolved colours to suit animal pollination.

Around Australia there are plant communities with different pollinators. For example, Macquarie Island has no bees, and flies are the only animal pollinator.

We assembled data from different locations, including a native habitat in mainland Australia where both bees and flies forage, to model how different insects influence flower colour signal evolution.

Measuring flower colours

Since we know different animals sense colour in different ways, we recorded the spectrum of different wavelengths of light reflected from the flowers with a spectrometer. We subsequently modelled these spectral signatures of plant flowers considering animal perception, allowing us to objectively quantify how signals have evolved. These analyses included mapping the evolutionary ancestry of the plants.

Generalisation or specialisation?

According to one school of thought, flower evolution is driven by competition between flowering plants. In this scenario, different species might have very different colours from one another, to increase their chances of being reliably identified and pollinated. This is a bit like how exclusive brands seek customers by having readily identifiable branding.

An alternative hypothesis to competition is facilitation. Plants may share preferred colour signals to attract a higher number of specific insects. This explanation is like how some competing businesses can do better by being physically close together to attract many customers.

Read more:
Plants use advertising-like strategies to attract bees with colour and scent

Our results demonstrate how flower colour signalling has dynamically evolved depending on the availability of insect pollinators, as happens in marketplaces.

In Victoria, flowers have converged to evolve colour signals preferred by their pollinators. The flowers of fly-pollinated orchids are typically yellowish-green, while closely related orchids pollinated by bees have more bluish and purple colours. The flowers appeared to share the preferred colours of their main pollinator, consistent with a facilitation hypothesis.

Our research showed flies can see differences between flowers of different species in response to the pollinator local “market”.

On Macquarie Island, where flies are the only pollinators, flower colours diverge from each other – but still stay within the range of the flies’ preferred colours. This is consistent with a competition strategy, where differences between plant species allow flies to more easily identify the colour of recently visited flowers.

When both fly and bee pollinators are present, flowers pollinated by flies appear to “filter out” bees to reduce the number of ineffective and opportunistic visitors. For example, in the Himalayas specialised plants require flies with long tongues to access floral rewards. This is similar to when a store wants to exclusively attract customers specifically interested in their product range.

Our findings on fly colour vision, along with novel precision agriculture techniques, can help using flies as alternative pollinators of crops. It also allows us to understand that if we want to see a full range of pollinating insects including beautiful hoverflies in our parks and gardens, we need to plant a range of flower types and colours.

Water management in the Northern Territory just keeps making headlines. The recent decision to grant an unprecedentedly large groundwater licence is a case in point.

The licence, granted to Fortune Agribusiness at Singleton Station, threatens springs and sacred sites near Alice Springs, and Aboriginal people, who are the custodians of these places, say they “are not being listened to”.

These media stories point to a wider problem with water law and water management in the Northern Territory. New legislation passed just this month is set to make it worse.

Under the cover of responding to a COVID-induced economic slowdown, the Northern Territory government is set to undermine hard-won national standards of water governance. This includes one of the most important advances in Indigenous water rights: the reservation of water for Aboriginal land owners to use or trade.

The Northern Land Council called the water law reforms a “betrayal of the interests of all Territorians”.

With even more regressive reforms on the books, the future of the NT’s water is looking more like its frontier past.

The NT’s history of undermining Aboriginal economic development

Water is a valuable resource, especially in the drier zones of Australia. The sheer volume of the Alice Springs water licence, in particular, represents a new form of resource extraction that rivals mineral extraction in scale.

Just as in the 19th and 20th centuries, the rampant reach of the Crown to appropriate and control natural resources to the detriment of Aboriginal peoples is evident. Analysis of the actions of the NT government in land rights disputes since the 1970s showed it made “immense areas of land and resources” available to commercial interests at virtually no cost.

A major participant (and beneficiary) of the government’s efforts to prevent land claims was the Northern Territory Land Corporation. Its role included holding title to certain lands, thereby removing them from the category of land over which claims could be made under the Land Rights Act.

History is being repeated in today’s water reforms. The Northern Territory Land Corporation has now been repurposed to accelerate the transfer of water rights to commercial interests. This move could make it harder for Aboriginal people to access water.

Why is Northern Territory water governance so weak?

In 2004, states and territories across Australia signed the National Water Initiative, which laid a foundation for good water management. On almost all counts, the Northern Territory is not compliant.

Australia, it’s time to talk about our water emergency

Only 5% of the Northern Territory is covered by water allocation plans. Under NT law, environmental water is protected through provisions in water plans – which means it is largely unprotected in the 95% of the territory without a plan.

Major decisions about water use are made by the water controller, who wears multiple hats. They are the water regulator, the chief executive of the Territory’s environment department, and also sometimes a water holder through their role on the board of the Northern Territory Land Corporation. We think that this inevitably creates a perception of a conflict of interest, and objectively leaves the decisions open to criticism, even where the decisions are well based.

One of the only areas in which the NT is arguably ahead of the curve is the Strategic Aboriginal Water Reserve. It was introduced into law in 2019 because Indigenous people have historically been locked out of water allocation processes and denied water rights.

The reserve sets aside up to 30% of water rights in a water allocation plan area for Aboriginal economic development. The reserve is only available to Aboriginal people with recognised rights to land.

Water can only be accessed under the reserve through an allocation plan. Even then, if all the available water is allocated by the time the plan is prepared, the reserve will have no water.

New laws make NT water governance worse

On August 12, the NT parliament passed the first of two key pieces of water legislation. The Statute Law Amendment (Territory Economic Reform) Act creates “head licence” arrangements that will formally allow “speculative” water licence applications from land developers, including the NT Land Corporation.

As water licences in the NT cost nothing to acquire, developers can effectively hoard this water for free until they are ready to proceed, locking others out.

The second set of law reforms are in the environment omnibus bills, which have been recently delayed by the NT environment minister after widespread concern about inadequate consultation.

As currently written, these bills:

1. reduce the need to comply with water allocation plans when issuing a water licence

2. enable water trade to occur outside water allocation plan areas

3. reduce public notification requirements, including for dams, limiting public feedback.

If passed, these laws would reduce transparency and scientific rigour in water allocation and undermine public confidence in regulation.

Together, these proposed changes mean the Northern Territory government is less likely to invest resources to produce more water allocation plans (essential for Aboriginal Water Reserves). Even where they do, new “head licence” law means more water may be allocated by the time the plans come into effect, leaving less in the Aboriginal Water Reserve.

The future of water management in the Northern Territory

We can’t help but also draw a connection between the new legislation and the successful challenges to water licence decisions made by the water controller.

These include most recently the decision by the NT minister to cancel the Larrimah water licence (issued to the Northern Territory Land Corporation) on the grounds it lacked clarity on future water use and was therefore too “speculative”.

A similar challenge has been made to the decision to grant the 40,000 megalitre licence at Alice Springs. However, the new “head licence” arrangements could entrench speculative water use in the Northern Territory’s water law.

While the changes appear to be aimed at stimulating economic development, the package of law reforms (those passed in August and those still under consideration) weaken legal controls on the issuing of water licences. Considering the Northern Territory’s colonial history, these new laws seem like a way to make it harder for Aboriginal people to access water for economic gain.

The excessive scope of this package of new water laws is not dissimilar to the long campaign by mining companies and the Northern Territory government itself in opposition to Aboriginal land rights from the 1970s.

The Northern Territory government has a long, tragic history of weakening land and water rights for Aboriginal people, and the proposed laws could further entrench the national problem of water dispossession.

Love in Bright Landscapes: The story of David McComb of The Triffids, directed by Jonathan Alley

David McComb’s lyrics embed narratives of love and loss within the vastness of the Western Australian landscape. “The sky was big and empty, my chest filled to explode, I yelled my insides out at the sun, at the wide-open road.”

It’s a song “full of air,” explains Paul Kelly. The lyrics of McComb, who founded legendary band The Triffids with his friend Alsy MacDonald and brother Robert in 1978, evoke a palpable sense of place. The group attracted enthusiastic audiences at festivals, garnering critical acclaim as part of the Australian indie band invasion of Britain in the early 1980s.

“You don’t just hear these songs,” says Kelly in Jonathan Alley’s extraordinary documentary Love in Bright Landscapes? “You see them, feel and smell them.”

By the late 1980s, The Triffids were filling stadia all over Europe, performing songs such as Wide Open Road, Save What You Can and Bury Me Deep in Your Love. However, this didn’t guarantee commercial success. In 1989, they disbanded, leaving a legacy of tender, lyrical songs and memorable performances.

The band’s successes and frustrations, McComb’s ascendancy as songwriter and performer, his physical decline, and his early death in 1999, aged 36, are beautifully told in this film.

Alley has structured his documentary like one of McComb’s songs. The unfurling narrative is driven by an urgent sense of purpose and inspired by McComb’s “magpie aesthetic,” where everything makes a connection.

From his early life (described by those who loved and worked with him), an image emerges of a sensitive boy from a privileged background with high achieving parents. His mother Athel confesses he was “… different from the others; his life was singular”.

David met his best mate MacDonald at Christ Church Grammar School in the 1970s, where, coincidentally, I was Senior Art Master. Art was a means of escape, a way to make sense and break free. The inquiring, intelligent McComb brothers (David had three siblings) trooped through my classes. As McComb said in 1998, the stricter the school, “the better rock and roll music it can produce”.

As punk spread from London to Seattle and Claremont, David and drummer MacDonald formed a band called Daisy, making their own albums on cassette. Daisy morphed into The Triffids in 1978, drawing on the DIY energy that seems to coalesce around the western edge of continents.

In the documentary Hype, for instance, which chronicles the rise of the grunge scene in Seattle, the lack of mainstream infrastructure is described as liberating, making it possible for young musicians to imagine recording their own music, writing their own magazines, and distributing their work. In Perth, like Seattle, doing it yourself was the only way to get something happening.

A creative cauldron

As a result, these young musicians and entrepreneurs were free to break new ground and stir it up. “David was the original Punk, not Johnny Lydon,” says Alley, “… everything was up for grabs, he made no distinction between high and low culture”.

Friday essay: punk’s legacy, 40 years on

From the creative cauldron of Perth in the 70s emerged Hoodoo Gurus frontman Dave Faulkner, and bands like the Manikins, Kim Salmon and the Surrealists and The Triffids.

Despite McComb’s conviction that “nothing happens here, nothing gets done, but you get to like it,” The Triffids did make great music and performed some terrific gigs before leaving, first for Sydney, then London.

There they found the success that had eluded them. In 1984, they recorded a session with John Peel on BBC radio. By 1985 they were on the cover of New Musical Express. They were on the cusp of global success, playing major festivals and signed by Island records.

Through Alley’s scrapbook of home videos, photographs, and interviews, we hear how it all slowly unravelled. It’s a sad story of a driven musician whose creativity was the bulwark keeping his demons at bay. Fuelled by a regime of drugs, he died of a heart attack on February 2 1999. The conflict that informed his best work was internal.

“I woke to discover an inferior replica of myself,” wrote McComb in a diary note; “avoid madness” in another. This inner tension with his dark side was a catalyst for his songs but as Alley explains “… for David, his best self was his creative self.”

McComb joined the galaxy of rock and roll stars whose short lives continue to inspire generations. Still, albums like Born Sandy Devotional and songs like Wide Open Road remain potent markers in our cultural life.

For curator Annika Kristensen, McComb’s album title Love in Bright Landscapes — borrowed from the Spanish poet Rafael Alberti but made his own — is a lens through which to explore the social, political and cultural landscapes of Perth and Los Angeles.

Coincidentally on show currently at Perth Institute of Contemporary Art, the 14 artists from both cities she has selected locate stories of love, hope, desperation, and despair under the vast canopy of a shared open sky.

McComb, whose love stories inflected with pain, humour, and wistful longing bleed into imagery of expansive WA landscapes, would have been delighted.

Love in Bright Landscapes will premiere at Luna Leederville in Perth on September 9.

Love in Bright Landscapes, curated by Annika Kristensen, is at Perth Institute of Contemporary Art, until October 10

Governments worldwide have released emergency stimulus packages to support workers and businesses through the economic crisis COVID-19 has wrought.

These measures include financial support, credit relaxation and tax relief for small businesses and some individuals, but they benefit only some taxpayers.

New Zealand may need to consider more significant changes to the tax system to repay the unprecedented level of borrowing that has funded the pandemic response. Tax cuts, investment incentives, changes to filing deadlines and tax amnesties could all play a significant role in helping to alleviate COVID-19’s financial and economic impact.

My research explores whether, under current uncertain economic conditions, introducing a voluntary disclosure program for overseas income could help protect New Zealand’s pandemic-impacted businesses — and promote honesty in tax matters at the same time.

New Zealand’s tax system is primarily punitive, rather than encouraging tax compliance. If a taxpayer is operating outside the tax system, the consequences of re-entering may be harsh. This encourages even inadvertent offenders to remain outside the system.

Tax amnesties, also known as “tax forgiveness”, can help short-term tax collection, recoup lost tax revenue and allow taxpayers to “regularise” their tax compliance.

How a one-off tax on wealth could cover the economic cost of the coronavirus crisis

A low-cost compliance initiative

New Zealand has strengthened penalties for tax offences considerably during the late 1980s to protect existing voluntary compliance. The introduction of an Overseas Voluntary Disclosure (OVD) mechanism would not only improve compliance but boost future tax revenue. Taxpayers cannot hide from their tax obligations once they have disclosed overseas income.

Since 1990, the number of immigrants has increased in New Zealand. According to the 2018 census, 31% of New Zealand’s population are immigrants. One in ten are self-employed without employees, and 5% have employees.

Many of these immigrants own small businesses. As a result of COVID-19, they are dealing with cash-flow stress. They may not be fluent in English or be unaware of their tax obligations and are unintentionally non-compliant. They now face the ramifications and penalty costs of voluntary disclosure.

Of course, some taxpayers are intentionally non-compliant in reporting their offshore income and assets. Whether unintentionally or deliberately non-compliant, many are self-employed and may want to inject their undeclared overseas funds into their local businesses to offset cash-flow stress.

Irrespective of these taxpayers’ accidental or deliberate lack of compliance, the Inland Revenue Department (IRD) must support these small businesses through the current crisis.

Offshore tax investigations

New Zealand adopted the Automatic Exchange of Information (AEOI) mechanism, which allows the IRD to obtain information about offshore assets and funds for New Zealand tax residents to verify it is accurately reported for tax purposes. New Zealand completed its first information exchange in 2018.

Since 2019, the IRD has started sending letters to New Zealand resident taxpayers regarding foreign income and tax residence status. They are advised to disclose the foreign-sourced income in their tax returns.

Some taxpayers may falsely assume the IRD is randomly targeting them and may continue to hide their foreign income. For those non-compliant taxpayers, an audit investigation is the first option.

Read more:
Post-coronavirus, we’ll need a working tax system, not more taxes and not higher rates

My research shows that offering voluntary disclosure would substantially reduce administrative costs in cross-checking the millions of lines of additional data received under the AEOI policy.

To administer such a program effectively, the IRD must use the best strategies to encourage voluntary declaration. For example, the opportunity to declare should be offered once only. Enforcement strategies and sanctions for non-compliance should be credible, consistent and clear.

Tougher penalties and interest would apply to those who choose not to take advantage of the program. Research shows a well-administered tax amnesty program facilitates strong engagement.

My research suggests New Zealand should offer a robust voluntary disclosure initiative similar to Australia’s 2014 Project Do It. Australian tax administrators gave taxpayers a last chance to correct their offshore tax affairs before audits or litigation.

This allowed intentional and unintentional tax evaders to pay the debt assessed under amnesty conditions without fear of prosecution or compliance penalties. It succeeded in encouraging them to return to the tax system.

Deliberate tax evaders will get the message that if they do not declare offshore assets, severe punishments will be imposed. Voluntary disclosure would also help non-compliant taxpayers protect their businesses from the financial and economic turmoil COVID-19 has caused.

Australian schools are struggling to recruit and keep teachers. Low wages, overwork, difficult student behaviour, lack of support and stress are some of the reasons teachers leave the profession or have periods of sick leave.

More than half of teachers with a current teaching qualification are not working in education. States such as New South Wales are facing major difficulties in employing teachers. This is especially so in the case of casual teachers who are needed to replace stressed and sick teachers.

Part of the reason for the teacher shortage is Australia’s lack of support for graduating teachers to successfully transition into the profession.

How does this work?

The transition for graduate teachers into the profession can be very challenging and they need to be supported with a quality induction program. Such programs help new teachers learn more about their roles, gain confidence and refine their teaching skills.

They are especially important for new teachers learning how to effectively manage diverse classrooms and student behaviour.

According to the Australian Institute for Teaching and School Leadership, induction programs should be:

1. school-based

2. delivered over two years

3. embedded in daily practice

4. practice-focused to further develop teaching skills.

From doing research in this area, we know Australian schools have responded to this need and increasingly developed induction programs to support new teachers over the past decade.

But it can take teachers several years to find long-term employment, which means many new teachers miss out on effective induction programs.

Research from 2019 shows that, within the first two years of graduating, 60% of new teachers are employed as insecure replacement teachers. We know

• 30% of new teachers are employed on contracts of less than one year

• 30% of new teachers are employed as casual teachers.

This leaves many new teachers relying on the strategies they develop during their insecure work experience to manage diverse classrooms and difficult student behaviours.

Newly qualified teachers who aren’t involved in a good induction program are more likely to leave the profession within their first five years of teaching.

No induction affects students too

Teachers employed casually or on short-term contracts know it is important to understand students’ strengths, needs and interests, as well as build good relationships with them. But they often don’t have the time or opportunity to do this properly.

Read more:
Six ways to support new teachers to stay in the profession

They know curriculum and pedagogy are important, yet often don’t know what the regular teacher had planned. And they haven’t always got time to assess and understand the students’ learning needs.

Short-term teaching work leads to a reliance on surviving or just getting through the day. Typically, this means managing student behaviour using more reactive techniques such as rewards and consequences (punishments).

On top of this, newly qualified teachers may feel anxiety about their uncertain job prospects and the potential loss of income.

Teachers employed for a short term usually try to perform as well as they can, so they get a subsequent job. This means they are usually reluctant to let anyone know they need help. They are aware they are being scrutinised and it’s important they are seen as being capable of managing students’ behaviour. More controlling approaches can help them achieve this.

Such teaching approaches mean they are not attending to the students’ problem behaviours in a way that prevents them from reoccurring. This can lead to an escalation of these behaviours over time and result in the student being disaffected at school.

Read more:
How teachers are taught to discipline a classroom might not be the best way

Teachers need to develop a broad range of proactive strategies to build a positive learning environment and prevent student behaviour problems. They must also be able to intervene effectively to de-escalate issues when they arise.

Much of this learning is based on developing and refining classroom management strategies during the induction period with the support of colleagues.

We’ll keep losing teachers

Induction programs are focused more on permanent new teachers. But the majority of new teachers are contract or casual staff.

A one-size-fits-all approach to induction programs will not address the specialist needs of casual teaching staff, particularly graduate teachers who move regularly between diverse school settings as work demands require.

Read more:
Teachers shouldn’t have to manage behaviour issues by themselves – schools need to support them

Education departments should support schools, including financially, to include casual and contract teachers in meaningful induction programs. They should also think more creatively about what is possible because this problem rests with them.

If we don’t develop meaningful ways for new teachers to be inducted into the profession, we may keep losing them.

Last week the New South Wales government announced schools are scheduled to re-open in October. While face-to-face learning undoubtedly has benefits for both children and parents, the announcement left unanswered a series of important questions about how this can be done safely.

By the time NSW lifts restrictions (estimated to be around October), only 60-70% of the population in NSW — and possibly less in Australia — who are 16 years and over may be fully vaccinated.

The Australian Technical Advisory Group on Immunisation (ATAGI) has recommended vaccination for children 12 and over, but most of these children will not be fully vaccinated by October, and children under 12 will remain unvaccinated for now.

In NSW, with well over 1,000 cases a day and rising, there will still be substantial community transmission when schools open. It is unclear when schools in Victoria (where cases are also on the rise) will open, but there may still be some transmission in the state when they do.

So, what do we need to do to make sure kids are as safe as possible at school?

1. Vaccinate the adults around them

In California, a primary school outbreak occurred when an unvaccinated teacher, who came to work despite symptoms, read to students with their mask off. Most kids who became infected were well over 2 metres from the teacher, which confirms the 1-2m distancing rule is not effective for an airborne virus.

Every child and teacher in a classroom or childcare centre with an infected person is at risk. Shared air is the major way SARS-CoV-2 — the virus that causes COVID-19 — spreads.

Children often get the virus from the adults around them, so vaccinating adults in a child’s household, and teachers, can help protect them.

Vaccination is now mandatory for teachers in NSW, but around 67% have had one dose. This probably corresponds to less than 40% of the NSW population being fully vaccinated.

One dose of vaccination gives about 31% protection and two doses gives 67% (AstraZeneca) to 88% (Pfizer) protection against the Delta variant. Most kids will still be unvaccinated if schools in the two largest states re-open for the last term of the year. This means it’s even more important to ensure the adults are vaccinated.

2. Mandate masks for teachers and students

We can mandate masks in schools for teachers and students, and highly recommend mask use for younger children in childcare.

The American Academy of Pediatrics recommends masks for children two years and up; children over this age can wear masks without much trouble.

As mask use in schools has been more common overseas, there are now numerous toolkits (including translated versions) and recommendations to support children to wear a mask. For example, your child is more likely wear a mask if it has their favourite colour, sports team, character or special interest on it.

Importantly, a DIY cloth mask can be made to fit your child’s face and be high quality if key design principles are followed. It is important to ensure children have choices and understand the reason why they are wearing a mask (for instance: “When we wear a mask, the virus can’t jump from person to person.”

3. Ventilated classrooms

Classrooms can be ventilated by opening windows (ideally two windows at opposite ends of the room). If there is only one window, a fan can help move the dirty air out. If opening windows is not possible there is fortunately a cheap fix available — portable air purifiers, which dramatically reduce the viral load in classrooms.

Poorly ventilated schools are a super-spreader event waiting to happen. It may be as simple as opening windows

There are DIY methods for making air purifiers, too.

4. Reduce numbers of people indoors

Reducing the number of people packed together in a classroom can reduce the risk of COVID. For example, during high epidemic periods, if the decision is made to open schools, a group of kids can come in every second day and learn online on alternate days.

We have shown this approach, when combined with masks, reduces the risk of transmission on university campus.

Use of outdoor spaces for lessons is also a smart move as the weather gets warmer. While Delta can transmit outdoors, the risk is likely much lower.

5. Test school kids

Finally, rapid point-of-care testing in schools will help reduce transmission, and self-testing kits (when approved in Australia) can help.

Saliva tests are also a practical way to test children. These tests are now available in official health settings, so governments could make them available to schools.

What about childcare centres?

We also need to consider childcare centres. Contrary to popular narrative, a new study shows kids up to three years old transmit more than older kids. So, vaccinating childcare workers and parents of young kids is also essential.

All the measures above, except masks for 0-2 year olds, can easily be used in childcare settings.

Record numbers of children are being hospitalised with COVID-19 in the USA. It remains unclear whether the high numbers of sick children are due mostly to Delta’s increased transmissibility, or whether it also causes more severe disease in children, as it does in adults. Although the risk of severe disease remains much lower in children than adults.

Read more:
Under-12s are increasingly catching COVID-19. How sick are they getting and when will we be able to vaccinate them?

One thing we do know is that as vaccination rates increase in adults, unvaccinated groups, the largest of which is children, will be proportionally more at risk. The 70-80% targets for vaccination of eligible adults for relaxing restrictions corresponds to 56-64% of the whole population, which leaves plenty of room for Delta to spread like wildfire in unvaccinated adults and kids. So there is good reason to protect kids if we open schools.

In addition, the productivity losses from lockdowns are an important component of the estimated A$220 million daily economic cost in NSW alone. Sick kids make it harder for their parents to work productively, if at all. And they make it more likely parents themselves become sick and are unable to work.

Earlier this year, Prince Harry revealed he has used a therapy called EMDR to cope with anxiety and trauma, including trauma resulting from his mother Princess Diana’s death when he was 12.

He demonstrates the technique in the Apple TV+ docuseries The Me You Can’t See.

EMDR stands for eye movement desensitisation and reprocessing. But what is this therapy and how does it work?

Read more:
Thinking of seeing a psychologist? Here’s how to choose the therapy best for you

What is EMDR?

EMDR is a psychotherapy treatment that aims to reduce distressing emotions associated with traumatic memories.

It involves consulting with a trained psychologist, usually over about 12 sessions.

Broadly speaking, the sessions involve eight steps:

1. History and treatment planning: the psychologist will discuss the patient’s specific reason for coming and take a detailed history

2. Preparation: the psychologist will talk to the patient about what they can expect from EMDR. In this phase, the psychologist will also teach the patient relaxation techniques they can use to calm themselves during or after sessions

3. Assessment: the psychologist will ask the patient to select a vivid image in their mind relating to the memory they wish to work on. The patient will also be asked to focus on any negative beliefs about themselves, or negative emotions associated with the event

4. Desensitisation: the patient will be asked to hold the traumatic memory in their mind while following the movements of the psychologist’s finger back and forth with their eyes. The psychologist may also lead the patient in tapping (for example, the patient taps their knees with their hands in an alternating pattern) or auditory tones delivered through headphones. These alternatives to eye movements engage the same parts of the brain

5. Installation: the patient is guided to replace the original negative belief with a positive one

6. Body scan: the patient thinks of the original memory to see if there is any physical tension remaining in the body. Usually the memory processing is complete when the memory no longer causes the patient any distress. If it still does, step 4 will be repeated

7. Closure: this is the end of the session. If the memory has not yet been completely reduced in intensity, the psychologist will guide the patient in relaxation exercises to do until the next session

8. Reevaluation: this is the start of the next session, where the psychologist and the client assess the previous session’s work and reevaluate the treatment plan as needed.

Read more:
What is repetitive transcranial magnetic stimulation and how does it actually work?

The therapist continually checks in with the client throughout the process.

An important phase at the end of treatment involves looking to the future. The psychologist might ask the patient to imagine an anticipated challenge.

For example, if the patient had been in a car accident, they might imagine driving on a highway, perhaps at night or alone, and see if any distressing emotions arise. If they do, the patient might still need some more treatment.

A unique aspect of EMDR is that the person may not have to discuss any of their disturbing memories in detail. The psychologist may ask “What event do you remember that made you feel distressed?” and the patient may say, “It was something my father did to me.” The process can be done without any extra information.

How does EMDR work? And who can use it?

The dual activity of thinking about a distressing memory and rapidly moving the eyes from side to side appears to reduce the level of emotion in the memory.

One theory is that thinking about a traumatic memory and following something with the eyes requires more memory capacity than is available, therefore the distressing memory is not completely accessed and loses its strength.

EMDR therapy is most commonly used to treat traumatic stress symptoms and post-traumatic stress disorder (PTSD).

A review of 26 clinical trials showed EMDR treatments significantly reduced symptoms of PTSD, depression, anxiety, and distress in people with PTSD.

The use of EMDR in children with PTSD has been demonstrated to be effective too.

People with phobias or anxiety concerns can also benefit, as can people with depression.

More than half of Australians will experience trauma, most before they turn 17. We need to talk about it

While the research suggests EMDR is an effective approach to reducing trauma, there may be some risks or side effects involved. These include:

• an increase in distressing memories

• heightened emotions or physical sensations during sessions

• light-headedness

• vivid dreams

• the surfacing of new traumatic memories.

Should any of these occur, the treating psychologist would typically support the patient to process these during the sessions.

Is EMDR recognised?

The World Health Organization and the International Society for Traumatic Stress Studies both recommend EMDR therapy as a treatment for adults and children with PTSD.

It’s also endorsed by the Australian Psychological Society.

If you’ve wandered through a forest, you’ve probably dodged dead, rotting branches or stumps scattered on the ground. This is “deadwood”, and it plays several vital roles in forest ecosystems.

It provides habitat for small mammals, birds, amphibians and insects. And as deadwood decomposes it contributes to the ecosystem’s cycle of nutrients, which is important for plant growth.

But there’s another important role we have little understanding of on a global scale: the carbon deadwood releases as it decomposes, with part of it going into the soil and part into the atmosphere. Insects, such as termites and wood borers, can accelerate this process.

The world’s deadwood currently stores 73 billion tonnes of carbon. Our new research in Nature has, for the first time, calculated that 10.9 billion tonnes of this (around 15%) is released into the atmosphere and soil each year — a little more than the world’s emissions from burning fossil fuels.

But this amount can change depending on insect activity, and will likely increase under climate change. It’s vital deadwood is considered explicitly in all future climate change projections.

An extraordinary, global effort

Forests are crucial carbon sinks, where living trees capture and store carbon dioxide from the atmosphere, helping to regulate climate.
Deadwood — including fallen or still-standing trees, branches and stumps — makes up 8% of this carbon stock in the world’s forests.

Our aim was to measure the influence of climate and insects on the rate of decomposition — but it wasn’t easy. Our research paper is the result of an extraordinary effort to co-ordinate a large-scale cross-continent field experiment. More than 30 research groups worldwide took part.

Wood from more than 140 tree species was laid out for up to three years at 55 forest sites on six continents, from the Amazon rainforest to Brisbane, Australia.
Half of these wood samples were in closed mesh cages to exclude insects from the decomposition process to test their effect, too.

Some sites had to be protected from elephants, another was lost to fire and another had to be rebuilt after a flood.

What we found

Our research showed the rate of deadwood decay and how insects contribute to it depend very strongly on climate.

We found the rate increased primarily with rising temperature, and was disproportionately greater in the tropics compared to all other cooler climatic regions.

In fact, deadwood in tropical regions lost a median mass of 28.2% every year. In cooler, temperate regions, the median mass lost was just 6.3%.

More deadwood decay occurs in the tropics because the region has greater biodiversity (more insects and fungi) to facilitate decomposition. As insects consume the wood, they render it to small particles, which speed up decay. The insects also introduce fungal species, which then finish the job.

Read more:
Wood beetles are nature’s recyclers – with a little help from fungi

Of the 10.9 billion tonnes of carbon dioxide released by deadwood each year, we estimate insect activity is responsible for 3.2 billion tonnes, or 29%.

Let’s break this down by region. In the tropics, insects were responsible for almost one-third of the carbon released from deadwood. In regions with low temperatures in forests of northern and temperate latitudes — such as in Canada and Finland — insects had little effect.

What does this mean in a changing climate?

Insects are sensitive to climate change and, with recent declines in insect biodiversity, the current and future roles of insects in deadwood are uncertain.

But given the vast majority of deadwood decay occurs in the tropics (93%), and that this region in general is set to become even warmer and wetter under climate change, it’s safe to say climate change will increase the amount of carbon deadwood releases each year.

It’s also worth bearing in mind that the amount of carbon dioxide released is still only a fraction of the total annual global deadwood carbon stock. That is, 85% of the global deadwood carbon stock remains on forest floors and continues to store carbon each year.

We recommend deadwood is left in place — in the forest. Removing deadwood may not only be destructive for biodiversity and the ability of forests to regenerate, but it could actually substantially increase atmospheric carbon.

Photos from the field: zooming in on Australia’s hidden world of exquisite mites, snails and beetles

For example, if we used deadwood as a biofuel it could release the carbon that would otherwise have remained locked up each year. If the world’s deadwood was removed and burned, it would be release eight times more carbon than what’s currently emitted from burning fossil fuels.

This is particularly important in cooler climatic regions, where decomposition is slower and deadwood remains for several years as a vital carbon sink.

What next?

The complex interplay of interactions between insects and climate on deadwood carbon release makes future climate projections a bit tricky.

To improve climate change predictions, we need much more detailed research on how communities of decomposer insects (such as the numbers of individuals and species) influence deadwood decomposition, not to mention potential effects from insect diversity loss.

But insect diversity loss is also likely to vary regionally and would require long-term studies over decades to determine.

For now, climate scientists must take the enormous annual emissions from deadwood into account in their research, so humanity can have a better understanding of climate change’s cascading effects.

If you stood in the middle of the Nefud Desert in central Arabia today, you’d be confronted on all sides by enormous sand dunes, some rising more than 100 meters from the desert floor.

The few scraggly bushes make poor browse for the herds of goats and camels that eke out a living in this harsh environment. But this wasn’t always the case.

Our research published today in Nature shows that in repeated pulses over the past 400,000 years, the Nefud Desert landscape received monsoon rains that resulted in rolling grasslands, flowing rivers and large lakes home to thousands of wild donkeys, antelopes and hippos.

Humans also inhabited these green corridors as they made their way out of Africa, only to disappear when conditions deteriorated again.

Among other findings, we present the oldest dated evidence for hominins in Arabia, in the form of stone tools dated to about 400,000 years ago. The Homininae subfamily is the group of humans of which Homo sapiens is the sole survivor.

Early movements out of Africa

Today Arabia is one of the world’s driest places, and was long thought to have played little role in human prehistory.

While the rich and long-studied Levant and the Mediterranean regions were considered critical for the dispersal of people out of Africa, it was thought most humans would have avoided places like the Arabian “Empty Quarter” — due to the harshness of its environmental conditions.

But detailed scientific investigations over the past few decades have been slowly changing these ideas. A rich stone tool culture has now been recovered from the surfaces of many ancient and dried out lakebeds in Southwest Asia.

However, because these were from isolated beds — often hundreds of kilometres apart — and restricted to surface scatters, it was difficult to determine who had left these tools, when, and where they came from.

In collaboration with the Heritage Commission of the Saudi Ministry of Culture and other Saudi colleagues, our international team of researchers has been working in Saudi Arabia, Southwest Asia’s largest country, for the past decade.

We have recorded and studied a wealth of stone tools and animal fossils emerging from the sands and ancient lakebeds. And we’ve made some startling discoveries.

We recovered a Homo sapiens finger bone, among other fossils, from an ancient Saudi Arabian lakebed known as Al Wusta. These remains were dated to 85,000 years ago. This finding shows modern humans had made it out of Africa at least 20,000 years before the genetic evidence indicates we left.

It has been thought (and many still believe) Homo sapiens only left Africa about 50-65,000 years ago. Our finger bone finding challenges this view, as do other discoveries – including from Madjedbebe in Australia.

Buried tools and pigments tell a new history of humans in Australia for 65,000 years

What happened to the group of people from Al Wusta remains unknown. They may have moved further into Asia, or retreated back to Africa. Or they may have become locally extinct.

A green Arabia

We also report a series of archaeological sites associated with multiple lakes across two locations which tell the story of human prehistory going back 400,000 years. The first of these locations, Khall Amayshan 4, is a depression located between large sand dunes covering 60,000 square metres.

In this single depression we found individual lakebeds dated back to 55,000, 100,000, 200,000, 300,000 and 400,000 thousand years ago. And each of the five lake phases is represented by its own unique archaeological signature.

Today different populations around the world can be identified by their cultures, which include the tools they use, how they’re made and how they use them. Think chopsticks across Asia and forks in Europe, for example.

These tools are passed on to successive generations, even if those generations move from their point of origin. The way people made and used stone tools in the past also reflected patterns of cultural inheritance.

So by studying and comparing the stone tools from Arabia with those from surrounding regions, we can find out not just when people were living and moving through the region, but also where their ancestors had moved from and how they changed as they moved.

The most striking thing we found was that each assemblage of stone tools recovered from each ancient lakebed was very different from the others.

Our detailed examination of the lakebeds and the mammal fossils they preserved, including from hippos, clearly pointed to how much wetter, greener and more productive each of those phases were compared to the region today.

The different technologies associated with each green phase indicate there was no long-term continuity in the populations in the area. Instead, different populations, perhaps even different species of hominin, were moving in and out with each phase.

At the Jubbah Oasis around 150 km east of Khall Amayshan 4, two further sites – Jebel Qattar 1 and Jebel Umm Sanman 1 – filled in the last of the gaps in the timeline. These sites presented different stone tools dating to around 200,000 and 75,000 years ago, also associated with green phases.

Each of these phases occurs during wetter climatic periods, which are wetter due to the northern movements of the monsoon, bringing increased rainfall to the desert. Once the climate shifted back, however, conditions became arid again and humans and other fauna disappeared from Arabia.

Prehistoric desert footprints are earliest evidence for Homo sapiens on Arabian Peninsula

Our findings reveal the intimate association between early human migrations and patterns of climate change — wherein different groups of humans repeatedly made it out of Africa when conditions became favourable.

And this happened long before the dispersal event of 50-65,000 years ago, which finally saw their descendents permanently colonise other regions.

Yet dozens of questions remain. Were some of these migrations from northern Neanderthals? What became of these different populations? Where did they go? Could some have made it to Southeast Asia and hence to Australia?

The human story won’t be told completely until we explore more long-neglected areas, much like our ancestors once did.

The history of the Australian Labor Party is both proud and miserable. At the federal level, it has spent considerably more time in opposition than in office, holding government for just 26 of the 66 years since the end of the second world war.

It has been a party of debilitating, long-running splits. One was over conscription during the first world war. Another was over how to respond to the Great Depression. The worst split, over the influence of communists within the ALP and the Catholic groups that fought against it, extended from the 1950s to the 1970s.

It was so deep, so enduring, that it came to be known simply as The Split and kept Labor in opposition for 23 years straight.

That’s the miserable part. What about the pride? The ALP has, through the decades, survived the disruptions and eventually found its way back to office, even if only for brief periods as was the case under the leadership of Jim Scullin (1929-32), Gough Whitlam (1972-75), Kevin Rudd (2007-10; June-September 2013) and Julia Gillard (2010-13).

Since Federation, the ALP has enjoyed just two decent runs in office, under arguably the party’s four best leaders. John Curtin and then Ben Chifley headed a Labor government from 1941 to 1949. And the Labor government led first by Bob Hawke and later by Paul Keating governed for five terms in 1983-96.

In keeping with its remit as a standard-bearer of social democracy, Labor has habitually been the party of ideas, change and legislative ambition. This internal dynamism, drawing from the party’s members and its affiliated unions, which themselves have millions of members, has been what has helped Labor overcome its disappointments and blunders.

With the government on the ropes, Anthony Albanese has a fighting chance

On the three occasions in the past 50 years that voters have decided to elect Labor to government from opposition, the party has gone to them with an established, well-articulated, wide-ranging set of policy proposals. It has never just fallen into office.

Whitlam came to power with an extensive reform agenda dubbed The Program – another Labor product that attracted capitalisation. He sought to implement it with an unyielding determination so fierce that it ultimately weakened his tenure.

Hawke offered a wide-ranging economic and social policy accord with the union movement as well as a formal consensus approach that included the corporate sector.

Rudd’s program in 2007 was less coherent and far-ranging but it did encompass a new workplace relations regime, a carbon emissions trading scheme and ambitious policies on education, broadband and manufacturing.

Each time, Labor took office after voters bought its message that there were substantial problems in Australian society that needed fixing.

The personalities and capabilities of the party’s leaders have counted for a great deal. But, above all, policy and ideology have been decisive factors in Labor’s triumphs and troubles throughout its long history.

How times have changed. More than two years into Anthony Albanese’s leadership, and with an election likely to be called less than six months from now, the Labor Party has offered few real signs of its plans for the nation.

Albanese’s approach so far has been to emphasise what he won’t do. He has overseen the stripping back of the party’s platform and junked proposals deemed to have hurt Labor at the last election, covering franking credits, capital gains tax and negative gearing.

On climate change, voters have been told to wait until closer to the election to be told how Labor would reach zero net carbon emissions by 2050. Policy pronouncements in most key areas are being pushed off into that nebulous “closer to the election” timeframe.

Labor is set to have itself a nervy little Christmas. It’s not too late to make 2021 sing

Essentially, Albanese has asked himself “what would Bill Shorten do?” and then done the opposite. As leader, Shorten saw off two Liberal prime ministers in Tony Abbott and Malcolm Turnbull. He did this by going in hard against them – a strategy he continued against the third Liberal leader he faced, Scott Morrison – while also releasing a torrent of challenging policy ideas.

At the 2016 election, this approach almost got Shorten across the line. In 2019, he failed again even though the opinion polls had suggested he would win.

Shorten’s approach of setting the political agenda did not produce electoral success, so Albanese has dedicated himself to not reproducing it. Judging that in 2019 Labor had too many policies, a confusing set of messages and a deeply unpopular chief salesman, he has backed himself in as a considerably better salesman who cannot be tripped up because he is in no danger of offering too much, too soon.

Nowhere was this better demonstrated than in Albanese’s budget reply speech in May. The government had thrown out its entire budget strategy, the nation was roiled by the pandemic, and the vaccine rollout was a shambles. Albanese used this nationally televised prime time appearance to talk about social housing – a worthy policy area, for sure, but an exceedingly strange choice for that moment.

The Labor leader’s risk-averse strategy seems to rest on an assumption that there is a natural equilibrium in national electoral politics – that an open-minded public approaches each election as a contest between evenly matched contenders. History suggests, however, that when it comes to electing Labor to power that is not true.

Clearly, Shorten was not popular enough among voters to get Labor over the line. There appears to be less antagonism and disdain towards Albanese in the community, but is he sufficiently more popular to make a difference? Here, we are left to rely on opinion polls, a fraught enterprise after their failures at the 2019 election.

On personal measures such as satisfaction and preferred prime minister, Albanese rates higher than Shorten but still scores a negative approval rating and lags behind Morrison in Newspoll and the Nine papers’ Resolve Political Monitor. To put it crudely, while Albanese is not as unpopular as Shorten, he could not be said to be popular; he is certainly not more popular personally than Morrison, his direct opponent.

Albanese’s supporters, mindful that the prime minister is expected to call an election less than five months from now, point to the latest Newspoll, which shows Labor ahead of the government 54-46 on a two-party preferred basis, as a sign that his strategy is working.

Coalition slumps but Morrison gains in Newspoll; electoral changes to curb micro parties

Shorten’s backers did the same thing at the end of 2018. In November and December of that year, just five months before the election, Newspoll had Labor with an even bigger lead, 55-45. Come the election, Labor’s two-party preferred vote was 48.5%.

It’s true political leaders live to create history rather than follow it, but it’s also the case that a Labor leader who pursues a strategy of keeping out of trouble in the hope that his opponent will fall over is taking a bold and unprecedented course. The result will be either the ALP’s most remarkable victory, or yet more heartbreak.

This article contains mentions of the Stolen Generations, and policies using outdated and potentially offensive terminology when referring to First Nations people.

There has been a long debate around whether First Nations people should be compensated for the past acts and conduct of settlers. Recently, the Commonwealth government created the Territories Stolen Generations Redress Scheme to compensate Northern Territory, the Australian Capital Territory and Jervis Bay Stolen Generations survivors.

The primary purpose of the redress scheme is to

help the Stolen Generations to heal the trauma from being forcibly removed from their family.

The redress scheme seeks to specifically “recognise the harm and ongoing trauma of forced removal from family for Stolen Generations survivors” and “assist with the healing of this trauma for the Stolen Generations survivors”.

A way to consider the nature and purpose of any redress scheme is to reflect on whether reconciliation can be achieved through engaging with injustices of the past.

This redress scheme raises questions about the ability of Australia to address the needs of First Nations peoples. Australia still hasn’t properly compensated First Nations people after the recommendations of the Bringing Them Home report 20 years ago.

Addressing past injustices

Damage was created through injustices against First Nations people, and it is the legacy of this damage that Australia needs to address.

This legacy stems from the history of modern settler colonialism, which is defined as

a distinct type of colonialism that functions through the replacement of Indigenous populations with an invasive settler society that, over time, develops a distinctive identity and sovereignty. Settler colonial states include Canada, the United States, Australia, and South Africa.

The discovery of Indigenous children’s bodies in Canada is horrific, but Australia has similar tragedies it’s yet to reckon with

In 1997, the Human Rights Commission issued the Bringing Them Home report. This landmark document identified the intention of the removal policies was to destroy Aboriginal culture:

one principal effect of the forcible removal policy was the destruction of cultural links. This was of course their declared aim.

The report noted this practice was a form of genocide:

When a child was forcibly removed that child’s entire community lost, often
permanently, its chance to perpetuate itself in that child. The inquiry has concluded that this was a primary objective of forcible removals and is the reason they amount to genocide.

On this basis, federal and state governments have been well informed that policies imposed on First Nations people were genocidal in nature.

Morrison government sets up redress scheme for survivors of Stolen Generation in territories

Limitations of the recent redress scheme

The redress scheme concedes the finding by the Bringing Them Home report that “most [Aboriginal] families have been affected in one or more generations, by the forcible removal of one or more children.”

However, there are limitations to this proposed scheme.

First, the Bringing them Home report is over 20 years old. It would have been more accurate to refer to a more recent report. Organisations such as The Healing Foundation have created many recent reports while working with Stolen Generations survivors.

Second, the purpose behind the redress scheme is to provide financial compensation for the damage caused by the policies and actions impacting Stolen Generations survivors — but only in the territories. It raises questions about other states committing to compensating and providing redress for Stolen Generations survivors.

Third, the nature of trauma requires greater consideration. This ongoing trauma is not just the loss of immediate and extended family and community – but the disconnect from respective lands and culture.

Genocide affects more than one member of the family, and is carried on through generations. So, the issue of trauma suffered by Stolen Generations survivors and their descendants needs to be considered more broadly.

What government should do to help survivors

Over the years, Stolen Generations survivors have attempted to seek justice through litigation, such as the case of Cubillo v Commonwealth. This case sought redress and compensation for the past injustices of policies and practices designed to separate Lorna Cubillio and Peter Gunner from their families when they were children.

However, the High Court found the plaintiffs were not able to sue the Commonwealth for negligence, despite the abuse they endured.

A one-off payment to Stolen Generations survivors isn’t the best way to approach long-term and intergenerational trauma. It would be more effective to provide ongoing support for these survivors through culturally safe health services. It would also be more beneficial for the government to have discussions with Stolen Generations survivors and their families about their respective needs to heal.

This would need to include the consideration of trauma experienced by other Stolen Generations survivors who might not qualify under the eligibility criteria of the redress scheme.

For example, descendants of Stolen Generations are not covered by the redress scheme proposal, despite many of them being impacted by intergenerational trauma.

Australia has a colonial settler legacy, and its effects continue to cause suffering to the families who had their children taken from them. Most have yet to be recognised or compensated. These are the silent victims of policies designed to destroy their culture and the future of their families.

A just society would be able to engage with its past and not shy away from it. However, the colonial settler society of Australia is yet to fully face its past and the legacy of the foundations it was built on, as it struggles to comprehend the nature of a just society.

The Pfizer and Moderna mRNA vaccines are some of our best weapons in the fight against COVID-19. They’re highly effective and many millions of people around the world have received their doses.

These vaccines are the first to be made synthetically, that is, they are made outside of a living cell.

Some posts on social media grasp onto the fact they are not “natural” and have created anxiety in vaccine-hesitant people by playing on this point.

So what does it mean for the mRNA vaccines to be synthetic, and why is that OK?

How did we develop our first synthetic vaccines?

Humans have been inoculating with germs to train our bodies to fight infectious diseases for a long time.

Even before the famous experiments of Edward Jenner (credited with developing smallpox vaccine) in the mid 18th century, Chinese and some European societies were using material from cow pustules to protect against smallpox.

From smallpox to polio, vaccine rollouts have always had doubters. But they work in the end

In the 20th century vaccine production gathered pace, using weakened or inactivated viruses.

Many viruses for vaccines are grown in chicken eggs, making this a problem for those allergic to eggs. Some of the newest vaccines, like the AstraZeneca COVID-19 vaccine, are grown in cells in large fermentation tanks. Recombinant protein vaccines, such as the hepatitis B vaccine, are made inside bacteria, then purified for use.

So we now have a whole range of different types of vaccines, each made differently, providing protection against different conditions. The thing all these vaccines have in common is that they are grown inside a living cell, so might be considered “natural”.

The mRNA vaccines are the first synthetic vaccines.

mRNA is a temporary genetic instruction that tells our cells to make a particular protein. It consists of a central portion with the genetic code for the protein and shorter portions either side that are important for the “readability” of the code.

mRNA vaccines are made in reaction vessels (large containers), and involve first making mRNA, then wrapping that in oily coats.

To make the mRNA, we use methods figured out in the 1970s, in a process known as “transcription”, where a DNA template is copied, creating an mRNA version of the genetic sequence.

This mRNA production is very similar to what happens when our cells make our own mRNA. The oily coats are also made synthetically and are very similar to lipids in our cells.

Why is synthetic OK?

The definition of synthetic is where a substance or compound is made by chemical synthesis, especially to imitate a natural product.

What is important to recognise is that, from a chemical perspective, a compound is the same, whether it was made by a living organism inside a cell, or whether it was made in a lab. If a chemist synthesises a compound, and a biochemist extracts the same compound from a natural source, those two compounds are identical.

This understanding was developed in the 19th century, when the concept of “vitalism” was being challenged. Vitalism espouses that organic materials cannot be created from inorganic matter. But we know now this is not the case.

A classic experiment was reported by Friedrich Wöhler, who synthesised urea (a molecule also produced by our bodies and found in urine) by heating a chemical called ammonium cyanurate. The synthetic urea was identical to natural urea, even though his synthetic method was nothing like the biological production of urea.

We don’t even think about it, but many of us eat and drink a huge number of synthetic molecules each day.

Vitamin C in pills, for example, is usually synthetic, but it still works because it is identical to the vitamin C we get from fresh fruits and vegetables. In fact, many of the dietary supplements that we take are synthetic.

Some common medicines, like aspirin, are synthetic variants of naturally occurring biomolecules.

Other fully synthetic molecules, like aspartame (artificial sweetener), are consumed in large quantities, up to hundreds of milligrams per soft-drink can. These quantities are thousands of times greater than the doses of the mRNA vaccines (between 30 and 100 micro-grams).

Synthetic components of mRNA vaccines

While the components of mRNA vaccines are almost identical to the components in our cells, there are some differences.

mRNA is a chain of linked building blocks, or nucleosides. Most of the mRNA vaccine building blocks – the As, Gs and Cs that make up the mRNA genetic code – are the same as the ones in our cells, and are originally extracted from yeast.

Read more:
3 mRNA vaccines researchers are working on (that aren’t COVID)

The fourth building block, U, is replaced with a component called N1-methylpseudouridine to make the mRNA more stable and stop our cells breaking it up immediately.

Although this component is not normally found in our mRNA, this modified building block is found in some archaea, microbes that can be found in extreme environments on earth, but also in our guts and in our belly buttons.

How are mRNA vaccines broken down in our cells?

The vaccine mRNA gets degraded relatively quickly, just like our own mRNAs get degraded.

The individual mRNA building blocks are salvaged by our efficient cell recycling system, and can be used to make new mRNAs, while other parts are excreted in urine.

So after a few days there is unlikely to be any mRNA vaccine left in our bodies. But hopefully it will have done the job needed to teach our immune system to recognise SARS-CoV-2 and prevent the worst symptoms of COVID-19.

Read more:
What do I need to know about the Moderna vaccine? And how does it compare with Pfizer?

Actually, the ability to make mRNA vaccines outside of cells is one of the strengths of the technology. By eliminating the need for growing cells, or viruses, in some ways it simplifies vaccine production.

On the other hand, synthesis involves it’s own complex technical steps, but in the coming years we will likely see innovation in simplifying this too. In fact, the World Health Organization is calling for all countries in the developing world to learn to make mRNA vaccines.

Hopefully when the next pandemic hits the world will be ready.

If you’ve wandered through a forest, you’ve probably dodged dead, rotting branches or stumps scattered on the ground. This is “deadwood”, and it plays several vital roles in forest ecosystems.

It provides habitat for small mammals, birds, amphibians and insects. And as deadwood decomposes it contributes to the ecosystem’s cycle of nutrients, which is important for plant growth.

But there’s another important role we have little understanding of on a global scale: the carbon deadwood releases as it decomposes, with part of it going into the soil and part into the atmosphere. Insects, such as termites and wood borers, can accelerate this process.

The world’s deadwood currently stores 73 billion tonnes of carbon. Our new research in Nature has, for the first time, calculated that 10.9 billion tonnes of this (around 15%) is released into the atmosphere and soil each year — a little more than the world’s emissions from burning fossil fuels.

But this amount can change depending on insect activity, and will likely increase under climate change. It’s vital deadwood is considered explicitly in all future climate change projections.

An extraordinary, global effort

Forests are crucial carbon sinks, where living trees capture and store carbon dioxide from the atmosphere, helping to regulate climate.
Deadwood — including fallen or still-standing trees, branches and stumps — makes up 8% of this carbon stock in the world’s forests.

Our aim was to measure the influence of climate and insects on the rate of decomposition — but it wasn’t easy. Our research paper is the result of an extraordinary effort to co-ordinate a large-scale cross-continent field experiment. More than 30 research groups worldwide took part.

Wood from more than 140 tree species was laid out for up to three years at 55 forest sites on six continents, from the Amazon rainforest to Brisbane, Australia.
Half of these wood samples were in closed mesh cages to exclude insects from the decomposition process to test their effect, too.

Some sites had to be protected from elephants, another was lost to fire and another had to be rebuilt after a flood.

What we found

Our research showed the rate of deadwood decay and how insects contribute to it depend very strongly on climate.

We found the rate increased primarily with rising temperature, and was disproportionately greater in the tropics compared to all other cooler climatic regions.

In fact, deadwood in tropical regions lost a median mass of 28.2% every year. In cooler, temperate regions, the median mass lost was just 6.3%.

More deadwood decay occurs in the tropics because the region has greater biodiversity (more insects and fungi) to facilitate decomposition. As insects consume the wood, they render it to small particles, which speed up decay. The insects also introduce fungal species, which then finish the job.

Wood beetles are nature’s recyclers – with a little help from fungi

Of the 10.9 billion tonnes of carbon dioxide released by deadwood each year, we estimate insect activity is responsible for 3.2 billion tonnes, or 29%.

Let’s break this down by region. In the tropics, insects were responsible for almost one-third of the carbon released from deadwood. In regions with low temperatures in forests of northern and temperate latitudes — such as in Canada and Finland — insects had little effect.

What does this mean in a changing climate?

Insects are sensitive to climate change and, with recent declines in insect biodiversity, the current and future roles of insects in deadwood are uncertain.

But given the vast majority of deadwood decay occurs in the tropics (93%), and that this region in general is set to become even warmer and wetter under climate change, it’s safe to say climate change will increase the amount of carbon deadwood releases each year.

It’s also worth bearing in mind that the amount of carbon dioxide released is still only a fraction of the total annual global deadwood carbon stock. That is, 85% of the global deadwood carbon stock remains on forest floors and continues to store carbon each year.

We recommend deadwood is left in place — in the forest. Removing deadwood may not only be destructive for biodiversity and the ability of forests to regenerate, but it could actually substantially increase atmospheric carbon.

Photos from the field: zooming in on Australia’s hidden world of exquisite mites, snails and beetles

For example, if we used deadwood as a biofuel it could release the carbon that would otherwise have remained locked up each year. If the world’s deadwood was removed and burned, it would be release eight times more carbon than what’s currently emitted from burning fossil fuels.

This is particularly important in cooler climatic regions, where decomposition is slower and deadwood remains for several years as a vital carbon sink.

What next?

The complex interplay of interactions between insects and climate on deadwood carbon release makes future climate projections a bit tricky.

To improve climate change predictions, we need much more detailed research on how communities of decomposer insects (such as the numbers of individuals and species) influence deadwood decomposition, not to mention potential effects from insect diversity loss.

But insect diversity loss is also likely to vary regionally and would require long-term studies over decades to determine.

For now, climate scientists must take the enormous annual emissions from deadwood into account in their research, so humanity can have a better understanding of climate change’s cascading effects.

Imagine it’s summer in Australia and a bushfire is bearing down on your suburb. Are you the pragmatic type – you’ve swapped phone numbers with the neighbours, photocopied your ID and have your emergency plan at the ready? Or are you the sentimental type – you’ve backed up the family photos but forgotten to insure the house, or don’t have an evacuation plan for the cat?

Our research out today shows when it comes to getting ready for disasters, there are four types of people. And this matters, because good disaster preparedness doesn’t just help people during and immediately after a disaster – it can also mean a quicker recovery.

The research, commissioned by Australian Red Cross, examined the experiences of 165 people who lived through a disaster such as fire and flood between 2008 and 2019. We identified a number of steps people wished they’d taken to prepare for disaster, such as protecting sentimental items, planning where the family should meet if separated and better managing stress.

The Black Summer bushfires, this year’s New South Wales floods, the storms around Melbourne and even COVID-19 remind us how disasters can disrupt people’s lives. Hopefully, examining the hard-won lessons of those who’ve lived through the worst life can throw at us will help individuals and communities better prepare and recover from these events.

Our key findings

The survey questions focused on preparedness actions people took before a disaster, their experience of a disaster and recovery.

Participants were 18 years or older and had experienced a disaster between January 2008 and January 2019. This allowed time for people to experience the challenges and complexity of the recovery process.

Among our key findings were:

• feeling prepared leads to a reduction in stress when dealing with the recovery process. And the less people are stressed, the better their recovery up to ten years after a disaster.

• generally, the more people do to get prepared, the more they feel prepared. However, one in five respondents who reported not feeling prepared had undertaken actions that should have made them feel prepared. And 3% said they were prepared when they hadn’t undertaken any action, which mostly comes from the lack of knowledge of the most efficient preparedness actions.

• the source of advice matters. More of those who received preparedness advice from Australian Red Cross – either directly or through its Get Ready app – had recovered. Those who had no preparedness training or received advice from family or friends were least likely to report having felt in control during the emergency.

3 ways to prepare

Three distinct groups of preparation actions emerged, which we outline below.

Protect my personal matters:

• develop strategies to manage stress levels
• protect or back up items of sentimental value
• make copies and protect important documents such as identification papers, wills, financial documents
• make plans for reunification of family if separated during an emergency.

Build my readiness:

• identify sources of information to help prepare for and respond to an emergency
• find out what hazards might affect their home and plan for them
• use preparedness materials such as bushfire survival plans.

Be pragmatic:

• make a plan for pets/livestock/animals
• swap phone numbers with neighbours
• take out property insurance.

Those who had taken action to prepare for disaster were asked what other actions they wished they’d taken. The top answer was having copies of important documents, such as ID and financial papers, that are potentially complicated to replicate and may be needed during recovery.

The full range of answers is below:

Which preparedness type are you?

Our research showed four types of persona emerged in terms of preparing for a disaster. Hopefully, identifying these groups means preparedness messaging can in future be customised, based on people’s characteristics.

Have a look at the graphic below – is there a type you identify with the most?

Recovery is complex

Our survey asked if people felt they had recovered from the disaster. Importantly, we did not propose a standard definition of recovery, which allowed respondents to define their recovery in their own way. We then sought to determine how a person’s disaster preparation affected recovery.

Nearly 18% of respondents said they had not recovered at the time of the survey. Surprisingly, 86% of those said they took action to get prepared (compared to 76% of those who had recovered). But those who had not recovered were more likely to feel their preparation actions were not enough. Importantly, 86% also experienced high levels of stress during the recovery, compared to 60% who had already recovered at the time of the survey.

Interestingly, the proportion of respondents who found the recovery process slightly stressful, somewhat stressful or extremely stressful are comparable (15%, 16% and 16% respectively). However, four out of ten respondents reported high levels of stress during the recovery.

What’s more, a greater proportion of those who had not yet recovered required government assistance after the disaster (71%), relative to those who felt they had recovered (38%).

In the group of those not yet recovered, people earning less than A$52,000 a year were over-represented.

Ready for anything

Our research shows being prepared can help reduce the long-term impacts of a disaster. The level of disaster preparedness in the Australian population is traditionally low, and so it’s important to demonstrate the benefits to ensure more people get ready for emergencies.

Preparedness programs should have a greater focus on preparing for the long-term impacts of a disaster. And these programs should differ based on people’s characteristics and they type of preparation support they need, particularly focusing on those who have less capacity to prepare and recover from the disruption of disaster.

What are the three biggest challenges Australia faces in the next five to ten years? What role will the social sciences play in resolving these challenges?

The Academy of the Social Sciences in Australia asked these questions in a discussion paper earlier this year. The backdrop to this review is cuts to social science disciplines around the country, with teaching taking priority over research.

One Group of Eight university, for example, proposes to cut the number of anthropology and sociology staff from nine to one. Positions across the social sciences are to be reclassified from teaching and research to teaching-only.

In addition, research funding is increasingly going to applied research. The federal government wants research that has greater engagement with industry and can be shown to contribute to the national interest.

The confluence of funding changes and loss of revenue from fee-paying international students comes on the back of other ominous long-term trends. Since the 1980s, successive federal governments have undermined perceptions of the importance of the social sciences compared with science, technology, engineering and mathematics (STEM).

Defunding arts degrees is the latest battle in a 40-year culture war

The latest policy involves a major shift in the purpose of Australian universities — to produce “job-ready graduates”, with more emphasis on industry engagement. The restructuring of funding is touted as an investment in the sciences. Fees have increased for social science students.

Today’s problems call for social science expertise

All this is happening at a time, during a pandemic, when the social sciences could not be more relevant and necessary. The challenges we face make it vital that the sciences work in partnership with the social sciences.

The pandemic has highlighted issues such as attitudes to vaccination and behaviour change, fake news and the politics of science, the vulnerability of people in care, roles and responsibilities of the state and the citizen, and gender disparities of the pandemic’s impact, to name a few. To tackle such issues we need to understand the social and cultural diversity underpinning people’s beliefs and values and how these interact during a global emergency. That’s the work of social scientists.

For example, gender analyses of the impacts of COVID-19 have revealed:

• women are 22% more likely to lose their jobs
• 20 million girls worldwide will never return to school
• a paltry 23% of emergency aid targets women’s economic security.

These impacts are likely to be long-lasting due to systemic gender inequality. But to remedy such impacts we need to understand the context of cultural and social structures.

It is social science research that reveals how the pandemic is compounding the precarity and inequality that women face. Around the world cultural norms restrict women’s independence and mobility, and burden them with unpaid care work and unequal access to resources. Women are disproportionately concentrated in the social, care and education sectors that have been hit hardest by the pandemic.

Pandemic widens gap between government and Australians’ view of education

Beyond the pandemic, the social sciences equip students to tackle the complex problems we face in the 21st century. Social sciences provide the skill set to:

• understand the nature of individuals, communities and cultures (the human condition)
• gain a broad comparative perspective on questions and concerns of the world today
• appreciate how the crises of this century impact how we live.

Fields of study include development studies, sustainability, anthropology, sociology, gender and race, Indigenous studies, human security, political science and economics. This makes the social sciences directly relevant to countless pressing issues. These include the pandemic and vaccine hesitancy, climate change, race and gender relations, inequality and poverty, mass migration and refugees, and authoritarianism.

Events in the news give us a sense of the complex social phenomena that require social science analysis to be fully understood. Examples include Black Lives Matter, #MeToo, March 4 Justice, the aged care royal commission, community support for the Tamil asylum-seeker family from Biloela, and the Federal Court victory for a group of teenagers that means the environment minister has a duty of care to protect children from the harms of carbon dioxide emissions.

Anthropologists, sociologists and political scientists provide the evidence that enables us to apply the solutions to globally important issues in local settings. For example, we have the science to prevent the spread of COVID-19 and create vaccines. But how do we achieve the social and behavioural change required for sanitation, vaccine uptake, mask-wearing, social distancing and so on? In short, how do we translate that science into good public policy?

In another example, it’s one thing to understand climate science, but how do we then ensure people know what they can do about it in their everyday lives? Expert analysis and translation by social scientists gives us insights into why certain social change occurs or doesn’t.

Job-ready? Social science graduates are

Social scientists have perhaps never been in greater demand. They are employed across public and private sectors, in environmental sustainability, community and international development, refugee and humanitarian agencies, health and education services, business and social enterprise, minerals and resource development, agriculture and land management, politics and policy. Employers value social science graduates for their analytical skills, cultural awareness, effective communication and language skills.

Indeed, arts, humanities and social science graduates are more employable than science graduates.

Humanities graduates earn more than those who study science and maths

The pandemic should have reminded us why we need the insights from the social and behavioural sciences to help align human behaviour with the advice of experts. We have become acutely aware that pandemics are complex social phenomena. Divestment from the social sciences at this precarious moment in time is remarkably short-sighted.

You may have already downloaded to your phone a digital certificate proving you have received one or two doses of a COVID vaccine. Its dark-green colour calls to mind the “Green Pass” now in use in European countries, which is required to gain access to venues such as restaurants, museums and some public transport.

These “vaccine passports” (also available to those who have recovered from COVID-19, or tested negative within the past 72 hours) have been met with a good deal of protest. In France, for example, more than 200,000 people turned out to protest against the Pass Sanitaire, which is requireed to dine out, drink in a bar, visit a hospital or travel on a long-distance train. The numbers at these events, though, are eclipsed by the millions who have rushed to get vaccinated, reviving stalling rollouts.

Australia’s Prime Minister Scott Morrison has vacillated on the issue of vaccine passports (as he has on many pandemic issues).

In May he supported the passport idea for interstate travel. Then he backed away from the idea in the face of opposition from state premiers and the Coalition’s own ranks. In mid-August, however, he was again speaking in favour of passports for interstate travel. By last week he was even more supportive, calling them sensible and saying businesses had a legitimate” right to refuse entry to anyone refusing to get vaccinated.

Predictably enough, there is passionate opposition to any form of vaccine passport — mostly, though not exclusively, from the political right. But polls show overwhelming support. A YouGov poll published the week, for example, shows 66% support (with 21% opposed and 13% undecided).

Findings from behavioural economics suggests this is likely to continue.

Framing decisions

Most modern work in behavioural economics can be traced back to the work of psychologists Amos Tversky and Daniel Kahneman (winner of the 2002 Nobel memorial prize for economics).

The pair introduced the idea of “framing” — the way in which a problem in presented, affecting the decision made — in their classic 1981 paper “The framing of decisions and the psychology of choice”.

The paper demonstrated the power of framing through an experiment that asked American and Canadian university students to decide on a response to a hypothetical (at the time, though more relevant today) “outbreak of an unusual Asian disease”

Participants were asked to imagine preparing for an outbreak expected to kill 600 people by choosing from alternative programs to combat the disease.

One group of participants was asked to choose between “A” and “B” programs:

• Program A: “200 people will be saved”
• Program B: “there is a 1/3 probability that 600 people will be saved, and a 2/3 probability that no people will be saved”

In this scenario 72% of participants preferred program A.

A second group of participants was asked to choose between “C” and “D” programs:

• Program C: “400 people will die”
• Program D: “there is a 1/3 probability that nobody will die, and a 2/3 probability that 600 people will die”

In this scenario 78% preferred program D — the same outcome as program B. The framing of the issue — lives saved versus deaths — was critical.

Similar findings have been reported from many other studies, most notably in the work of George Lakoff, author of Don’t Think of an Elephant: Know Your Values and Frame the Debate.

Australia’s context differs to Europe

How does this relate to vaccine passports?

In European countries, where the strategy has been to “live with COVID”, managing infection rates without the restrictions adopted by Australia and New Zealand, vaccine passports have been introduced in response to the surge in cases resulting from the Delta variant. The passports have been framed as restricting the freedom of the unvaccinated to do things for which the passport is now required. Resistance has been expressed primarily in these terms.

In Australia, by contrast, it is highly likely much of the country will be in some form of lockdown by the time vaccination rates are high enough to relax controls in any significant way.

In this context, introducing vaccine passports can be framed as restoring freedom to those who are vaccinated. We’ve already seen this in a small way, with the NSW government’s decision to allow small outdoor gatherings provided everyone present is vaccinated.

Grattan on Friday: Vaccine passports are a better tool than mandating jabs for all jobs

With this framing, opposition to passports will be divided between two groups.

One group is the hardcore anti-vaxers and opponents of any public health mandate, who want to resist any push for vaccination.

The other group is at the opposite end of the spectrum — those who think even the much smaller risks posed by fully vaccinated people are too great to bear. To confuse things, some people may switch between one argument and the other depending on the audience. This division makes it even less likely that effective opposition will emerge.

Protesters might make some noise, but in practice the biggest hurdle for vaccine passports will likely be the administrative failures that have plagued every aspect of Australia’s response. Two problems to already emerge are security flaws enabling certificates to be forged, and incomplete records meaning people can’t download their certificate.

We can only hope such problems are sorted out by the time vaccine passports become a reality.

Our writers nominate the TV series keeping them entertained during a time of COVID.

Binge watching a gut-wrenching story about the early years of the HIV/AIDS epidemic might seem like a strange choice in Sydney right now. What possible solace could be found in a story about a group of young friends in 1980s London who found their joyful steps towards the creation of a queer world fractured by fear and death?

I rewatched the five-part British TV series It’s a Sin in lockdown recently, and the sorrow that reverberates through the show resonated a little more potently than it did on my first viewing earlier this year. It also, though, in its elaboration of joyful possibilities fractured by an epidemic, helped me make sense of some of the intangible losses of lockdown.

As counsellor Neeraja Sanmuhanathan has written, many in lockdown are feeling “disenfranchised grief”. Yet even naming these feelings risks insensitivity, because others are dealing with grief much more difficult to bear.

New South Wales Premier Gladys Berejiklian speaks from a rhetorical playbook of unity, discipline and shared citizenship obligations to compel Sydneysiders to stay at home under lockdown. It’s a Sin can help us consider how the sorrows and hardships of these obligations are unevenly distributed, for they depend on what your home looks like, and whether it is your primary source of nourishment and care.

We soon come to love, even if they sometimes behave a little poorly, Olly (a star-making turn from Year and Years frontman Olly Alexander), Roscoe (Omari Douglas), Colin (Callum Scott Howells) and Jill (Lydia West) as their lives converge in a share house, “the Pink Palace”, which becomes the emotional centre of the story.

They are a diverse lot, both in ambition and background. All, in different ways, seek to escape the futures mapped for them by others, although what they would like to become is much less clear.

Exuberant confusions and experiments are at the centre of the first few episodes. I challenge anyone not to be totally undone by Colin’s endearing uncertainties as he takes tentative steps into homosexual worlds. We see parties, drinks at the pub, exciting intimacies. And The Pink Palace develops its own tender traditions and vocabularies; the housemates exclaim “La” to each other as they enter and exit the house. These are the everyday familiarities that feel like a hug of recognition.

Rather than a world organised by biological family and the romantic couple, friendship is sovereign here. These new kinds of friendship prioritise pleasure and joy. They are full of disordering excitements that produce new ways to understand their world.

This is why the emergence of HIV/AIDS, which haunts the show from the first episode, feels so tragic. Just as historical change produced the possibility of forging queer public worlds — spaces for dissident desires — an epidemic ravaged them, unleashing fresh waves of homophobia.

Created by Russell T. Davies, each episode of It’s a Sin takes place a few years apart, tracing the impact of the epidemic on queer lives over a decade. We watch these tentative worlds shattered first by fear, then by death, doubly punished by a state that refused to help. In the UK and US, gay men in the early years of the epidemic were seen as a problem to be managed and a sin to be expunged rather than partners in the possible response.

There are lessons here about the importance of engaging with — rather than disciplining and policing — communities. The “Australian-Response” to HIV/AIDS was hailed as a success because the state engaged with and learnt from those vulnerable to the disease to develop community-led policy.

Part of the mastery of the show is that we, as viewers, share the fears of these young men and their friends. We know what is coming, even if they don’t. We find ourselves wondering who from the Pink Palace and their friends will be struck down.

In one episode, one of the housemates is forcibly and legally detained in hospital after his diagnosis. His mother and friends hire a lawyer to release him so he might be cared for by those who understand him.

Watching this makes for difficult viewing. Queer networks, however, power the show. They hold those who are sick, comfort those who are stricken by loss, and politically mobilise to force the state to act. They share grief with parents who lose their sons, holding to account families whose love turned out to be conditional.

This is queer intimacy as life-saving.

This is friendship as primary nourishment and radical politics.

Less rigid boundaries

The emotional and narrative centre of It’s a Sin is a home. But this home looks quite different to the one our leaders today might imagine when they issue stay-at-home orders — almost always referring to a family when doing so. It’s certainly not organised around a couple (and the children).

The boundaries around the Pink Palace are porous, people come and go, and you never know who might be at the breakfast table. It is, however, affirming in its instabilities. For Roscoe, this home is an escape from a familial home that was a place of violent rejection.

And that, I think, highlights the challenge facing so many queers in lockdown today. Queer lives are often organised around friendships, (as indeed are many others not oriented around a romantic couple). Boundaries around queer homes may be less rigidly drawn. The intimacies and communities that sustain living queer, enabling joyful exploration of who we might become with each other, are often forged both within and beyond the walls of our home.

This is why so many queer friends I know are struggling. Lockdown hasn’t simply shut down our capacity to dance and have fun, or to have casual (and thus apparently meaningless) sex. It has turned the spaces beyond our homes, in which we nourish our queer selves, into sites of danger. It has turned having your friends over and snuggling on the couch into a breach of duty.

Which is to say, much like the HIV/AIDS epidemic, the impact of lockdown is being felt unevenly and with different effects.

On the release of It’s a Sin, there was much public discussion about the ways in which this show re-imagined the experience of HIV/AIDS for a generation far enough removed from the early years of the epidemic to understand it as history rather than experience.

Watching this series now, though, I find myself mourning the everyday, public, and non-familial intimacies of queer life lost to us during lockdown. It might not have provided solace, but it has helped me to explain my sense of loss.

It also made me wail. And perhaps having a good cry is what many of us need.

As well as her interviews with politicians and experts, Politics with Michelle Grattan now includes “Word from The Hill”, where she discusses the news with members of The Conversation politics team.

In this episode, politics + society editor Amanda Dunn and Michelle discuss the June quarter national accounts, released on Wednesday. While this quarter was better than expected, the September quarter is certain to be negative as a result of the prolonged lockdowns.

They also mark the change this week in the national COVID debate, as the Victorian government, following NSW, admits defeat in the battle to get to COVID zero.

COVID has been spreading quickly in western NSW Indigenous communities where low vaccination rates and poor conditions make for a toxic mix. The first Indigenous death occurred in Dubbo this week.

As efforts intensify to deal with the NSW outbreak Pat Turner, CEO of the National Aboriginal Community Controlled Health Organisations (NACCHO) joins the podcast. As well as discussing the NSW situation, she warns of the vulnerability of communities in Western Australia, attacks religious figures promoting dangerous misinformation, and says Indigenous communities can’t safely open at 70% or 80% vaccination rates.

On western NSW, where there are hundreds of cases, Turner says crowded and bad housing make it “almost impossible to isolate and quarantine”. People in Wilcannia are “having to isolate in tents – in Australia in 2021”.

In WA First Nations communities, the low vaccine coverage “is a very significant concern to all of us”.

“It has by far the lowest uptake, with less than 10% of its population 12 years and over fully vaccinated”.

“I would think that the first death for Aboriginal and Torres Strait Islander people […] has been a wake up call for some, especially those who didn’t think that COVID would affect them. The reality is sinking in for many of those.”

One obstacle is the spread of false claims by god botherers.

“[Aboriginal] Pastor Geoffrey Stokes called out a circular that had been sent around by [a] so-called Indigenous prayer group in the goldfields of Western Australia. And it happened that it was a white bloke from Brisbane who had circulated the misinformation. So that was soon put to bed.

“But there are people and communities, Aboriginal communities that belong to groups like the Assemblies of God and, you know, other such religions that strongly believe that God will protect them.”

“God will not stop COVID killing our people. I’m sorry to the religious leaders who believe that, but I’m telling them that will not happen.”

While the national cabinet’s plan provides for easing restrictions for the general community at 70% and 80% vaccination levels of those 16 and over, Turner insists that can’t apply in Indigenous communities.

“No, no, no, 70 to 80% will not be good enough for our communities. We are aiming for 100% vaccination of Aboriginal and Torres Strait Islander people 12 years and over by the end of this year.”

Over the past 25 years, the name “Google” has become synonymous with the idea of searching for anything online. In much the same way “to Hoover” means to use a vacuum cleaner, dictionaries have recognised “to Google” as meaning to undertake an online search using any available service.

Former competitors such as AltaVista and AskJeeves are long dead, and existing alternatives such as Bing and DuckDuckGo currently pose little threat to Google’s dominance. But shifting our web searching habits to a single supplier has significant risks.

Google also dominates in the web browser market (almost two-thirds of browsers are Chrome) and web advertising (Google Ads has an estimated 29% share of all digital advertising in 2021). This combination of browser, search and advertising has drawn considerable interest from competition and antitrust regulators around the world.

Leaving aside the commercial interests, is Google actually delivering when we Google? Are the search results (which clearly influence the content we consume) giving us the answers we want?

Advertising giant

More than 80% of Alphabet’s revenue comes from Google advertising. At the same time, around 85% of the world’s search engine activity goes through Google.

Clearly there is significant commercial advantage in selling advertising while at the same time controlling the results of most web searches undertaken around the globe.

This can be seen clearly in search results. Studies have shown internet users are less and less prepared to scroll down the page or spend less time on content below the “fold” (the limit of content on your screen). This makes the space at the top of the search results more and more valuable.

In the example below, you might have to scroll three screens down before you find actual search results rather than paid promotions.

While Google (and indeed many users) might argue that the results are still helpful and save time, it’s clear the design of the page and the prominence given to paid adverts will influence behaviour. All of this is reinforced by the use of a pay-per-click advertising model which is founded on enticing users to click on adverts.

Annoyance

Google’s influence expands beyond web search results. More than 2 billion people use the Google-owned YouTube each month (just counting logged-in users), and it is often considered the number one platform for online advertising.

Although YouTube is as ubiquitous to video-sharing as Google is to search, YouTube users have an option to avoid ads: paying for a premium subscription. However, only a minuscule fraction of users take the paid option.

Evolving needs

The complexity (and expectations) of search engines has increased over their lifetime, in line with our dependence on technology.

For example, someone trying to explore a tourist destination may be tempted to search “What should I do to visit the Simpsons Gap”.

The Google search result will show a number of results, but from the user perspective the information is distributed across multiple sites. To obtain the desired information users need to visit a number of websites.

Google is working on bringing this information together. The search engine now uses sophisticated “natural language processing” software called BERT, developed in 2018, that tries to identify the intention behind a search, rather than simply searching strings of text. AskJeeves tried something similar in 1997, but the technology is now more advanced.

BERT will soon be succeeded by MUM (Multitask Unified Model), which tries to go a step further and understand the context of a search and provide more refined answers. Google claims MUM may be 1000 times more powerful than BERT, and be able to provide the kind of advice a human expert might for questions without a direct answer.

Are we now locked into Google?

Given the market share and influence Google has in our daily lives, it might seem impossible to think of alternatives. However, Google is not the only show in town. Microsoft’s Bing search engine has a modest level of popularity in the United States, although it will struggle to escape the Microsoft brand.

Another option that claims to be free from ads and ensure user privacy, DuckDuckGo, has seen a growing level of interest – perhaps helped through association with the TOR browser project.

While Google may be dominating with its search engine service, it also covers artificial intelligence, healthcare, autonomous vehicles, cloud computing services, computing devices and a plethora of home automation devices. Even if we can move away from Google’s grasp in our web browsing activities, there is a whole new range of future challenges for consumers on the horizon.

Scientists in South Africa have discovered a new viral variant of SARS-CoV-2, the virus that causes COVID-19.

It’s not a single virus but a clustering of genetically similar viruses, known as C.1.2.

The researchers, in a pre-print study released last week but yet to be peer reviewed, found this cluster has picked up a lot of mutations in a short period of time.

Indeed, this is what viruses do. They continually evolve and mutate due to selective pressures but also because of opportunity, luck and chance.

C.1.2 has some concerning individual mutations. But we don’t really know how they’ll work together as a package. And it’s too early to tell how these variants will affect humans compared with other variants.

There’s no need to panic. It’s not spreading widely, and it’s not at Australia’s doorstep. The tools we have in place work against SARS-CoV-2, whatever the variant.

Will it be more infectious or severe?

C.1.2 is distinct from but on a genetic branch near the Lambda variant, which is common in Peru.

It has some concerning individual mutations. But we don’t know how these mutations will work altogether, and we can’t predict how bad a variant will be based on mutations alone.

We need to see how a certain variant works in humans to give us an idea of whether it’s more transmissible, causes more severe disease or escapes the immunity we get from vaccines more than other variants.

At this stage we don’t know enough about how C.1.2 behaves in humans because it hasn’t spread enough yet. It represents less than 5% of new cases in South Africa, and has only been found in around 100 COVID cases worldwide since May.

It’s not yet listed by the World Health Organization as a variant of interest or a variant of concern.

The Lambda variant: is it more infectious, and can it escape vaccines? A virologist explains

Will it overtake other variants?

It’s early days, so it’s impossible to predict what will happen to C.1.2.

It could expand and overtake other variants, or it could fizzle and disappear.

Again, just because this virus has a bunch of mutations, it doesn’t necessarily mean the mutations will work together to out-compete other variants.

Delta is the kingpin variant at the moment, so we need to keep an eye on C.1.2 to see if it starts to push out Delta.

So, it’s important to keep watching it in case it starts transmitting widely. One group in Australia, the Communicable Diseases Genomics Network, monitors these developments closely.

Read more:
Why is Delta such a worry? It’s more infectious, probably causes more severe disease, and challenges our vaccines

There’s no need to panic

At this point, there’s no need for concern.

Australia still has its border restrictions in place, so the odds of this rarely occurring virus coming into the country and spreading are very low.

There’s no evidence our vaccines don’t work against it. Our vaccines provide protection from severe disease and death against all other SARS-CoV-2 variants thus far and there’s a good chance they’ll continue to do so against C.1.2 variants.

What’s the difference between mutations, variants and strains? A guide to COVID terminology

It won’t be long until we have a better idea of how C.1.2 behaves. There’s a lot of eyes on it, and we need to have patience as the data comes in.

Sensationalism and panic in the meantime isn’t going to solve anything.

New variants, and other bits of news amid the pandemic, are often latched onto and amplified by certain people and media. There’s a real risk this causes fear when it’s not needed, and inducing fear is a form of harm.

It is a tough time for the public because it’s hard to know who to listen to and trust.

I would say it’s best to listen to the experts, particularly organisations whose job it is to track and communicate risks about these things, like the WHO and your local jurisdiction’s health department.

Don’t amplify or pay attention to obvious alarmism and extreme negativity, and make sure you’re getting your information from media sources that are trustworthy.

Vaccination remains our best single tool

The chances of new variants arising increases the more the virus spreads.

Vaccinating as many people as possible, as quickly as possible, is key to reducing the risk of new variants arising.

That’s not to say it will reduce the risk to zero and there will be no more variants. Mutations happen by chance, and happen in a single person. One way mutations can arise is in people whose immune systems are compromised — they mount an incomplete immune response and the virus adapts, escapes and is released with more mutations.

Nothing is perfect in biology. People’s immune systems respond in different ways, and a lot is based on individals’ immune history — how competent their immune system is and whether they have chronic disease.

We also won’t have every single person fully vaccinated, and vaccines aren’t 100% perfect, so there will still be some spread of the virus.

But vaccination reduces the risk a lot. We also know what else works to limit this virus, including ventilation, filtering air, masks and social distancing measures.
