10 年后澳大利亚将迎来的 2066 大变化
Core conclusion · Tlines extraction
Treasury's 2026 Intergenerational Report projects Australia's population rising from about 28 million to 39.3 million by 2065-66, with growth slowing to 0.9% a year from 1.4%. Deaths are expected to outnumber births by the 2060s. Real GDP growth averages 2% versus 3% previously, while real gross national income per person rises 55%. AI adoption, ageing and housing affordability are central themes.

Key arguments
- Population growth slows to 0.9% a year over 40 years, with deaths exceeding births from the 2060s and net overseas migration assumed to continue.
- Ageing shifts weight onto productivity: real GDP grows 2% a year versus 3% previously, though living standards still rise.
- AI is described as a defining influence, with use widespread but shallow; the Productivity Commission estimates a multifactor productivity lift above 2.3% over a decade, with considerable uncertainty.
- Intergenerational equity centres on housing: home ownership among 25-34 year olds fell 17 percentage points from 1981 to 2021.
Key numbers
- Projected population 2065-66
- 39.3 million
- Annual population growth (next 40 years)
- 0.9% (vs 1.4% prior 40 years)
- Australians aged 85+ by 2065-66
- 1.9 million (from ~625,000)
- Real GDP growth (next 40 years)
- 2% average (vs 3%)
- Real gross national income per person
- 55% higher
Main risks
- Long-term projections are not forecasts of exactly what will happen and carry wide uncertainty, especially around AI's eventual impact.
- Slower GDP growth and ageing strain finances, with more weight on productivity improvements that may not materialise.
- Housing affordability pressure on younger generations persists, with ownership rates well below 1981 levels.
