What is the capital city of Australia?

Canberra is the capital city of Australia and serves as the political and administrative center of the country. Established as the capital in 1913, it was chosen as a compromise location between the two larger cities of Sydney and Melbourne, both of which had been vying for the title of capital. As a planned city, Canberra was designed specifically to host the national government, featuring significant landmarks such as the Parliament House and the High Court of Australia.

In contrast, while Sydney and Melbourne are the two largest and most populous cities in Australia, they do not serve as the capital. Brisbane, known for its coastal city lifestyle, is also not the capital, as it is primarily the capital of the state of Queensland. Thus, given its unique role and historical significance, Canberra is correctly identified as the capital city of Australia.
