Australia has experienced consistent population growth since the mid-20th century, fueled by immigration, natural increase, and strong urban development. In 1950, Australia’s population was just 8.2 million, and by 2024 it reached 26.7 million. With one of the highest immigration rates among developed nations, Australia is projected to continue growing steadily throughout the 21st century, with the population expected to reach 43.1 million by 2100.
Australia’s Historical Population Growth (1950–2024)
Australia’s population has more than tripled over the past 75 years. Post-war migration, economic expansion, and rising urbanization transformed the nation into one of the fastest-growing developed countries.
- 1950s–1970s: Australia grew from 8.2 million in 1950 to 12.6 million in 1970, largely driven by post-war migration programs.
- 1980s–1990s: The population crossed 17 million by 1990, with strong economic growth supporting steady immigration.
- 2000s: By 2005, Australia surpassed 20 million, adding nearly 5 million people in just 15 years.
- 2010s–2020s: Growth continued, bringing the total to 26.7 million in 2024, with major cities like Sydney and Melbourne absorbing most of the increase.
