The capital of Australia is Canberra. Established as the capital in 1913, Canberra is located in the Australian Capital Territory (ACT). Its selection was a compromise between rival cities Sydney and Melbourne, both of which wanted to be the capital. The city is known for its national institutions, including the Parliament House, the High Court, and various national museums and galleries. Designed by American architect Walter Burley Griffin, Canberra's layout features expansive green spaces and a geometric design that reflects its significance in Australian governance.
