There are eight capital cities in Australia, each of which function as the seat of government for the state or territory in which they are located. Melbourne was the initial capital following the 1901 Federation of Australia. In 1927, the seat of national government was moved to the newly created city of Canberra, which continues to serve as the national capital.
Each capital city hosts the judicial, administrative and legislative functions for their jurisdiction. In the case of the states and internal territories, their capital cities also happen to be the most populous city in their respective jurisdiction.
The Australian external territory of Norfolk Island has its official capital at Kingston, although this acts merely as the administrative centre of government; its de facto capital is Burnt Pine.
