Advocacy groups and builders clash over what growth means for housing
Australia's population climbed to 27.9 million at 31 March 2026, up 1.4% over the year, reigniting debate over the pace of migration-driven growth even as the underlying numbers show migration easing slightly.
Migration remains the dominant driver, though it's cooling
According to the Australian Bureau of Statistics (ABS), the population grew by 392,700 people in the 12 months to March 2026. Net overseas migration accounted for 292,100 of that increase, down from 309,500 in the previous 12-month period, while natural increase (births minus deaths) added 100,600 people.
Bjorn Jarvis, the ABS's head of population statistics, said "our population was 27.9 million people at 31 March 2026, that's 392,700 more than the same time in 2025."
Western Australia posted the fastest growth of any state or territory at 2.1%, followed by Victoria and Queensland, both up 1.6%, while Tasmania grew slowest at 0.6%.
Advocacy groups argue growth is outpacing capacity
Not everyone views the figures as good news. Sustainable Population Australia (SPA), an environmental advocacy group calling for an end to population growth, argues the pace of expansion is straining infrastructure and the environment faster than governments can respond.
SPA national president Peter Strachan said current growth means "Australia will host 29 million people by January 2029," adding that this drives "a never-ending requirement for power and water, as well as supporting infrastructure, including dwellings, schools, hospitals, roads, and railway lines."
SPA communications manager Michael Bayliss linked the growth directly to housing supply pressure, pointing to the federal government's push to build 1.2 million new homes within five years as a contributing factor to native vegetation clearance debates.
Master Builders: migration isn't delivering the right workers
Not all reactions to the migration figures were about capacity strain – Master Builders Australia argues the system isn't yet delivering enough of the right migrants. The peak body welcomed changes announced the same day, including treating housing trades the same as university qualifications in the skilled migration points test, but CEO Denita Wawn said the reforms won't be enough on their own.
"That is a number wholly inconsistent with the scale of this challenge," Wawn said, referring to the roughly 7,040 skilled visa holders currently working in core construction trades nationally, against a construction workforce shortfall the group puts at 141,000 workers. A further 18,400 migrants already in Australia hold building qualifications but are working below their skill level due to slow skills recognition and licensing processes.
The workforce shortfall is one of several pressures on Master Builders' broader supply concerns: separate analysis by the same body forecasts Australia will fall 204,000 homes short of the National Housing Accord's 1.2 million target.
Many economists, by contrast, credit migration with supporting labour supply and economic growth.
Borrowing capacity and demand pressure ahead
Population growth, even at a slower migration pace, continues to underpin housing demand in fast-growing states like Western Australia, Victoria and Queensland – a factor worth weighing in borrowing capacity conversations with first-home buyers and property investors alike. The construction workforce shortfall Master Builders has flagged adds a supply-side risk too: without more tradespeople on site, new-build timelines and costs could stay under pressure regardless of demand.
