The Retirement Wave: How Australia’s Ageing Population Will Reshape Australia

Life expectancy has increased substantially across Australia. The pattern differs by sex and region, but the overall direction is clear. Longer lives mean that more Australians are spending a greater number of years in retirement.

The increase is not limited to Australians who have recently reached retirement age. Every older age group has grown over time, including people aged 80 and over. The chart also shows differences between males and females within the older population. As these groups continue to expand, Australia is likely to face greater demand for healthcare, aged care, suitable housing and retirement support.

Darker cells represent larger population groups. The heatmap highlights the large middle-aged cohorts that are moving closer to retirement and shows differences between males and females across the age structure.

Birth rates have declined among younger women, while childbearing has shifted towards women in their thirties. Lower fertility and later childbearing reduce the relative size of younger generations entering the future workforce, adding to the ageing of the population.

The population pyramid brings the story together. Large middle-aged groups are approaching retirement, while women form a greater share of the oldest age groups. This changing balance will influence workforce participation, retirement income needs and demand for health and aged-care services.

Australia’s retirement wave is being created by three connected forces. People are living longer, every older age group is expanding and fewer children are being born. The effect is not uniform across age groups or sexes. Planning for healthcare, aged care, retirement income and workforce participation will need to begin before the largest cohorts move into advanced old age.
