Australia grapples with AI revolution, migration caps, and unsolved murders

Australia is staring down a set of interconnected crises that will reshape the country over the next four decades, according to a Treasury report released this week. The intergenerational assessment, delivered by Treasurer Jim Chalmers, identifies five accelerating pressures: the economic upheaval from artificial intelligence, a fragmenting geopolitical order, the shift to clean energy, an aging population with falling birth rates, and industrial transformation driven by technology and climate. None of these challenges exists in isolation. A shrinking workforce means fewer people paying income tax at precisely the moment when government spending on defense, social services, and climate adaptation will climb. Life expectancy is climbing—women are projected to live to nearly 90 by 2066, up from about 86 today—but the working-age population that funds the system is contracting.

AI sits at the center of the Treasury's long-term forecast. Chalmers described it as the most consequential economic shift since the last intergenerational report in 2023, and potentially the biggest transformation of the coming generation. The modeling suggests that each additional 0.1 percentage point of productivity growth from AI could improve the fiscal bottom line by 0.7 percentage points and reduce gross debt by 0.3 percentage points within a decade—but only if Australia translates its high adoption rates into genuine workplace improvements. Australians are already adopting AI at rates higher than almost every other G20 nation. The question, Chalmers said, is whether the country can move from adoption to implementation, from having the tools to using them effectively.

While the Treasury maps long-term economic transformation, immediate crises are testing Australia's infrastructure and institutions. A Senate inquiry into telecommunications outages delivered its report this week, examining failures that have been linked to multiple deaths. The most prominent was an Optus triple zero outage on September 18, 2025, which disabled emergency call services. The inquiry expanded to include other carriers, including a Telstra outage in July this year. The committee made 11 recommendations, with one of the most significant urging the government to consider nationalizing triple zero—the emergency call service currently managed by Telstra with support from other carriers. Greens senator Sarah Hanson-Young said the telecommunications system is failing because large corporations have been allowed to regulate themselves while controlling essential services. She argued that Australians should be able to call for help from anywhere in the country and have their call connect, regardless of which network they use. "These companies are not putting the safety of Australians first," she said. "They're putting their profits first."

Meanwhile, policymakers are clashing over migration policy in ways that could ripple through food prices and regional economies. Labor, the Coalition, and One Nation have all recently announced plans to cap or reduce visa numbers. Home Affairs Minister Tony Burke proposed cutting net overseas migration from 292,000 this year to 225,000 by 2027-28. Queensland Premier David Crisafulli called the approach "nuts." Without temporary visa workers, he said, country towns grind to a halt during harvest seasons. Pubs run out of staff, farmers cannot pick fruit, and the cost of goods climbs for everyone. Crisafulli framed the issue not as sentiment but as economics: the produce in grocery trolleys will become significantly more expensive without sensible migration policy that allows regional work to continue.

Other stories this week underscored the fragility of systems and the persistence of unsolved tragedy. The ACT government announced a $500,000 reward for information in five unsolved murder and missing person cases, including the death of Keren Rowland, a 20-year-old nurse killed in 1971 whose family believes she was the first victim of serial killer Ivan Milat. The other cases span decades: Elizabeth Herfort, last seen in 1980; Megan Louise Mulquiney, last seen in 1984; Troy Hugh Forsyth, struck by a van in 1987; and David Abuoi, last seen in Canberra in 2012. Police minister Marisa Paterson said the families have never stopped seeking answers. An inquest also began this week into the deaths of six primary schoolchildren who died when a jumping castle became airborne during end-of-year celebrations at Hillcrest Primary School in Devonport on December 16, 2021. An inquiry revealed the castle was tethered at only four of eight anchorage points. The operator, Rosemary Gamble, was acquitted of criminal workplace health and safety charges in 2025, but the coroner's inquest will examine whether additional safety measures could have prevented the tragedy.

Environmental threats are also mounting. Four endangered Australian sea lions tested positive for H5N1 bird flu at breeding sites near Kangaroo Island in South Australia, including one pup. The first H5 death of a sea lion was recorded eight days earlier. Experts estimate only about 12,000 Australian sea lions remain, mostly in South Australia. The Invasive Species Council warned that while mass deaths have not yet occurred, multiple deaths in a single location could signal the devastation seen in South America and Antarctica is approaching. Spring migration and breeding events across the country could accelerate the virus's spread. In Western Australia, authorities called off a shark catch-and-kill operation after a fatal attack at Sorrento Beach on Friday. The 63-year-old victim's body was not recovered, and authorities concluded there was no evidence of ongoing white shark activity in the area.
