In which city is Australia’s Parliament House located?

Australia's Parliament House is located in Canberra, which is the capital city of Australia. Established as part of a compromise between Sydney and Melbourne, Canberra was chosen in 1908 as a neutral site to house the federal government. Parliament House, opened in 1988, is notable for its unique architectural design, which symbolizes democratic governance.

Canberra was specifically designed to serve as the political center of Australia, hosting key government departments and institutions. In contrast, Sydney and Melbourne, while significant cities in Australia, serve primarily as cultural and economic centers rather than as the political hub. Brisbane, also an important city, does not play a role in the federal government, making Canberra the correct answer.
