Australia’s Population Hits 28 Million as Growth Keeps Outpacing Old Forecasts

Australia’s population has reached 28 million, marking another major milestone for one of the world’s fastest-growing advanced economies. The latest figure reflects a steady upward trend that had already pushed the country past 27 million in recent years, according to reporting based on national projections and demographic data.

This latest jump highlights just how quickly Australia’s population has been expanding. The Australian Bureau of Statistics has previously reported that the country stood at 27,724,744 people at 30 September 2025, with annual growth of 423,600 people, or 1.6 percent. That growth was driven by both natural increase and net overseas migration, with migration making the larger contribution.

Why the 28 million mark matters

Crossing 28 million is more than just a symbolic headline. It reflects long-running shifts in migration, births, and urban development, and it increases pressure on housing, transport, healthcare, and infrastructure planning. The population is also rising faster than many earlier forecasts expected, a pattern that has been noted in demographic analysis over the past few years.

Australia’s growth has also surprised forecasters before. McCrindle previously noted that the nation reached 27 million more than 30 years ahead of some projections, and estimated that sustained growth could bring the next million much sooner than traditional models suggested.

What is driving the increase

The ABS data shows that Australia’s recent growth has come from a combination of natural increase and net overseas migration. In the year to 30 September 2025, natural increase contributed 112,600 people, while net overseas migration added 311,000.

That mix matters because migration has been the dominant force behind the country’s recent population gains. It has helped fuel growth in major cities and shaped demand for services, housing, and jobs across the country.

How Australia compares with earlier estimates

Demographic estimates published in 2026 placed Australia’s population in the high 28-million range, reinforcing the view that the country has continued to expand rapidly into this year. The ABS projection data also shows that Australia’s long-term trajectory still points significantly higher, with the population in 2022 projected to reach between 34.3 million and 45.9 million by 2071.

In practical terms, that means the 28 million milestone is not an endpoint. It is another waypoint in a much larger demographic shift that will shape Australia’s economy and public policy for decades.

What comes next

If recent growth rates continue, Australia is likely to keep adding people at a pace that challenges planners and policymakers. The country’s population growth has already pushed well beyond older expectations, and the latest milestone suggests that urban expansion, housing supply, and infrastructure investment will remain central issues.

For now, the headline is simple: Australia is bigger than ever, and it got there faster than many expected.
