Why it matters
- Treasury projects deaths will outnumber births in the 2060s, while population growth slows to 0.9 per cent a year.
- Housing prices have risen about 400 per cent since 1999 while Australia builds homes at roughly half the productivity rate of 30 years ago.
- A smaller workforce can support prosperity only if Australia builds more homes, lifts productivity and targets migration at productive capacity.
Australia's demographic bargain is changing. The Treasury's 2026 Intergenerational Report says deaths are projected to outnumber births for the first time in the 2060s. Population growth is expected to slow to 0.9 per cent a year over the next four decades, compared with an average of 1.4 per cent over the past 40 years.
That is a large economic fact hiding inside a distant forecast. A country that grows more slowly cannot rely on a bigger workforce to paper over weak productivity, expensive housing and an ageing population. Treasury expects the number of Australians aged 85 and over to triple by 2066, while the share of new health spending linked to ageing rises sharply.
The News
Australia's 2026 Intergenerational Report forecasts falling fertility, slower population growth and deaths exceeding births in the 2060s.
Sox’s View
The forecast is a deadline for supply side reform. Housing, productivity, energy and skills policy must do more of the work that population growth once did.
Room for Disagreement
Treasury presents migration, AI and clean energy as ways to manage demographic change. The harder question is whether Canberra will remove the planning, tax and regulatory barriers that keep those gains from reaching households.
The report still contains good news. It projects that the economy will be more than twice its current size over the next 40 years, with income per person 55 per cent higher by 2065 to 2066. Gross debt is projected to fall to 22.2 per cent of GDP in the mid 2050s before rising to 27.4 per cent by 2065 to 2066. Those are projections, not trophies. They depend on the country doing the hard work that makes them possible.
Housing is the first test. ABC's reading of the report finds that house prices have risen about 400 per cent since 1999, more than twice the pace of average income growth. Australia is building homes at roughly half the productivity rate of 30 years ago. Younger Australians are being asked to fund an older society while being priced out of the asset that once built household security.
Migration can ease the arithmetic, but it cannot substitute for reform. Reuters reports that the Treasury expects net overseas migration to fall before stabilising, even as care services face labour shortages. The sensible policy is to welcome people who add productive capacity, recognise useful skills quickly and stop treating a visa queue as a housing strategy.
The same logic applies to artificial intelligence and energy. Treasury identifies both as major forces over the next four decades. Australia should use them to lift output per worker, cut the cost of power and expand the tax base, rather than turn each new technology into another compliance industry. A smaller workforce can still support rising living standards if each worker has better tools and more room to build.
The demographic warning is therefore a useful deadline. Build more homes, make planning faster, let capital reach productive businesses and measure migration by skills and outcomes. Australia has time to choose abundance. It should spend less of it congratulating itself on forecasts and more of it making the forecasts come true.
