Australia Faces Negative Natural Population Growth by 2025

Australia is projected to enter negative natural population growth — where annual deaths exceed births — in the near term. This shift does not immediately mean the country’s total population will decline, as net overseas migration may continue to offset the shortfall. However, it marks the end of positive natural increase, defined as the numerical difference between live births and deaths.

Slowing growth and shifting demographics

A government intergenerational report, which models economic and demographic trends over the next four decades, forecasts that Australia’s annual population growth rate could slow to 0.9 per cent — down from an average of 1.4 per cent over the past 40 years. Two primary drivers underpin this projection: falling birth numbers and rising life expectancy.

Ageing population pressures health and care systems

Treasurer Jim Chalmers stated that the number of Australians aged 85 and over will triple by 2066. That demographic expansion will intensify demand for health services and aged care. As the elderly cohort grows, so too will the need for doctors, nurses, home-care workers, and residential aged-care staff. At the same time, the available working-age population may shrink relative to the number of people requiring those services.

Migrant labour underpins critical sectors

The government warns that regions with higher concentrations of older residents may face disproportionately acute shortages in health and aged-care workers — sectors currently reliant to a significant extent on migrant labour. Australia has long depended on immigrants to sustain population growth and fill labour market gaps. Yet net overseas migration is trending downward ahead of stabilisation, coinciding with tightened immigration rules amid escalating political debate over migrant intake levels.

Hospital beds, tax revenue, and economic output

This makes migration policy inseparable from the future viability of hospitals, care services, and broader economic growth — not merely population size. Australia previously avoided the demographic turning point seen in advanced economies such as Japan, Germany, and South Korea, where deaths have consistently outpaced births.

Broader structural transformations

The intergenerational report positions population ageing alongside artificial intelligence, energy transition, geopolitical tensions, and the economy’s shift toward services as one of the most consequential forces reshaping Australia’s future. The nation is therefore preparing not only for a change in birth and death counts, but for systemic transformation across labour markets, healthcare delivery, migration frameworks, and public finances — raising an urgent question: who will work and who will fund services as the population ages?
