Australia's population is currently around 27 million people, with a median age of 38.5 years. This population is expected to increase to between 34.3 and 45.9 million people by 2071, with the median age projected to rise to between 43.8 and 47.6 years. This changing population profile has a varying demographic, with First Nations people having a younger age profile and higher growth rate than non-Indigenous people. The population is also highly urbanized, with 86.51% of the population living in urban areas. The ageing of the population is considered the most dramatic change, with the proportion of people aged 65 and over expected to increase significantly. Fertility rates are also changing, with a continuing shift towards older ages.

Population ageing
Australia's population is ageing due to increasing life expectancy and sustained low fertility rates. This trend has significant implications for the country's social and economic landscape.
In the past few decades, life expectancy in Australia has increased steadily. This is largely due to improvements in healthcare and living standards. As a result, the proportion of older people in the population is growing. In 2017, the number of Australians aged 65 and above surpassed the global average, reaching 15.8%. This figure is projected to increase further in the coming years, with one in six Australians expected to be over the age of 65 by 2061.
The ageing population is a result of declining fertility rates as well. Australia's total fertility rate, which is the average number of babies per woman, has been below the replacement level of 2.1 since 1976. In 2020, it stood at 1.66. This trend is attributed to various factors, including delayed childbearing due to higher education and workforce participation among women, as well as the increasing costs of raising children.
The shift towards an older population has wide-ranging impacts. One key area of concern is the economic burden on the working-age population. As the number of retirees increases, there will be relatively fewer people in the workforce to support them. This could lead to a strain on government finances, with pension and healthcare costs for older Australians expected to rise significantly.
Additionally, the ageing population will have implications for healthcare services. Older people tend to have more complex and chronic health needs, requiring specialised care. This will likely result in an increased demand for aged care services, including residential aged care facilities and in-home care. There may also be a greater focus on preventative health measures to maintain the health and well-being of older Australians.
The social landscape will also be affected by population ageing. With older people making up a larger proportion of the population, there could be a shift in political and social priorities. Intergenerational relationships and the role of families in caring for older adults may also evolve.
In summary, Australia's changing population profile is characterised by an ageing population, driven by increasing life expectancy and low fertility rates. This trend has far-reaching consequences for the country, impacting the economy, healthcare system, and social dynamics. Addressing the challenges and opportunities presented by population ageing will be a key focus for policymakers and society as a whole in the coming decades.

Fertility rates
Australia's fertility rate has been in a state of flux over the past few decades, and this has had a significant impact on the country's changing population profile. The total fertility rate (TFR) refers to the average number of children that would be born to a woman over her lifetime, assuming she experienced the

Migration
Interstate migration within Australia is also a significant contributor to the country's changing population dynamics. People's movement between states and territories is influenced by factors such as economic opportunities, overseas immigration and settlement patterns, and individual lifestyle choices. Net interstate migration estimates are calculated using Medicare change of address records, defence data, and Census data on usual residence.
Population decentralisation in Australia has proven difficult, with cities continuing to grow faster than regional areas. This is due to cities offering better education and employment opportunities, attracting the majority of international movers. Australia's population is highly urbanised, with 86.51% of the population living in urban areas as of 2025, particularly along the southeastern coastline from southeast Queensland to Victoria.
The changing population profile of Australia also includes an increasing median age, projected to rise from 38.5 years in 2022 to between 43.8 and 47.6 years by 2071. This ageing population trend is a result of fertility rates remaining below replacement level and declining mortality rates. The working-age population is expected to decrease, while the proportion of people aged 65 and over will increase significantly, with a projected rise from 17% in 2022 to between 25% and 27% by 2071.

Population distribution
Australia's population distribution is uneven, with a high concentration of people living in urban areas along the southeastern coastline, from southeast Queensland to Victoria. As of 2025, 86.51% of the population is urban, amounting to 23,335,357 people. This urbanisation is driven by the pull factors of cities, including greater opportunities for education and employment, which attract the majority of international migrants.
The median age of the population is 38.3 years, with a projected increase to between 43.8 and 47.6 years by 2071. This ageing of the population is due to fertility rates remaining below the replacement level and declining mortality rates. The working-age population, those aged 15-64 years, is projected to decrease from 65% to between 59% and 60% by 2071. Meanwhile, the population aged 65 years and over is expected to increase from 17% in 2022 to between 25% and 27% by 2071. The number of people aged 85 and over is also projected to rise, from 2.1% in 2022 to between 5.2% and 6.4% in 2071.
The distribution of the population by household is also changing. There is a growing trend of people living alone, and the average number of people in each household is declining. This change in household composition has implications for housing policy and the availability of social support, particularly in the context of increasing pressures on younger generations.
