The Australian Capital Territory, known as the Federal Capital Territory until 1938, is a federal territory of Australia. Canberra, the capital city of Australia, is located in this territory. It is located in southeastern Australian mainland as an enclave completely within the state of New South Wales. Founded after Federation as the seat of government for the new nation, the territory hosts the headquarters of all important institutions of the Australian Government.
On 1 January 1901, federation of the colonies of Australia was achieved. Section 125 of the new Australian Constitution provided that land, situated in New South Wales and at least 100 mi from Sydney, would be ceded to the new federal government. Following discussion and exploration of various areas within New South Wales, the Seat of Government Act 1908 was passed in 1908 which specified a capital in the Yass-Canberra region.
