What is the total population of Australia?

The total population of Australia is approximately 25.8 million as of the latest statistics. This figure reflects Australia's growth due to factors such as natural increase and immigration. The population has continued to rise steadily, influenced by its high standard of living and attracting many migrants seeking opportunities. This demographic data is crucial for understanding various aspects of Australia’s socio-economic landscape, including urban planning, resource allocation, and public services.

The other population figures presented in the options do not accurately represent the current population of Australia. The lower estimates of 20 million and 22 million were pertinent in the past but do not reflect recent trends and the impact of migration in the 21st century. The figure of 30 million is an overestimation that does not align with the current statistical data available. Thus, the choice identifying the population as 25.8 million is correct, showcasing a realistic and up-to-date understanding of Australia’s demographic status.
