Australia's population has grown by more than 392,000 people in 12 months, and the Australia Bureau of Statistics says almost 75 per cent of that increase came from overseas migration. The numbers come from the state’s own counting machine, with ABS head of population statistics Bjorn Jarvis putting the total at 27.9 million people at 31 March 2026. That was 392,700 more than the same time in 2025.
Who Gets Counted, Who Gets Managed
Mr Jarvis said natural increase added 100,600 people to the population. He defined that as the number of people born minus those who died. Births were up 0.3 per cent and deaths were up 3.1 per cent. He also said 292,100 people were added to the population from net overseas migration from March 2025 to March 2026. That figure was lower than the 309,500 people added in the previous 12 months.
The state’s statistics don’t just record movement. They sort it, package it, and turn it into a neat annual percentage while the people behind the numbers keep living the consequences. The annual increase came to 1.4 per cent in the year leading up to March 2026. Most of that growth, by the ABS’s own account, came from people arriving from overseas rather than from births.
Migration, Managed From Above
In the past year, 557,500 people immigrated to Australia from overseas, a decrease of 4 per cent compared with the previous year. A further 265,400 emigrated from Australia in the same time period, a decrease of 2.2 per cent. Mr Jarvis said the net overseas migration figure came from subtracting the number of people migrating away from Australia from the number of people immigrating to Australia. Clean arithmetic. Messy lives.
Population data for the past two decades showed the annual change plummeted in early 2020 with the start of the COVID-19 pandemic. It peaked again in September 2023 before beginning a slow return to pre-pandemic levels in the following years. The timeline reads like a ledger of disruption, with the machinery of population management tracking every shift as people moved, stayed, left, or arrived under conditions they didn’t set.
All states and territories had some population growth in the year ending March 2026. Western Australia had the fastest growth rate, with an increase of 2.1 per cent or 64,200 people compared with the previous year. Tasmania was the slowest, with an increase of 0.6 per cent or 3,400 people. The majority of those immigrating to Australia moved to New South Wales, while Tasmania and the Northern Territory had the lowest numbers of overseas migration.
The Map of Uneven Growth
The figures show growth spread across the country, but not evenly. Some places absorbed far more of the movement than others, and the ABS data makes that hierarchy plain. New South Wales took the majority of those immigrating to Australia. Tasmania and the Northern Territory sat at the bottom of the migration pile. Western Australia grew fastest. Tasmania crawled.
That’s the shape of the system as the numbers present it: people moving through a country that measures them, ranks them, and records which places get the most bodies and which get the least. The ABS doesn’t hand out the jobs, housing, or services that make those numbers livable. It just counts the fallout and calls it population data.
Mr Jarvis’s figures show a country growing by 392,700 people in one year, with overseas migration doing most of the work. The state can tally the movement. It can’t hide the fact that ordinary people are the ones who absorb the pressure when the numbers rise, fall, or get shuffled from one region to another.
