On 1 January 1901, federation of the colonies was achieved after a decade of planning, consultation and voting. After the 1907 Imperial Conference, Australia and the other self-governing British colonies were given the status of "dominion" within the British Empire. The Federal Capital Territory (later renamed the Australian Capital Territory) was formed in 1911 as the location for the future federal capital of Canberra. Melbourne was the temporary seat of government from 1901 to 1927 while Canberra was being constructed. The Northern Territory was transferred from the control of the South Australian government to the federal parliament in 1911. Australia became the colonial ruler of the Territory of Papua (which had initially been annexed by Queensland in 1883) in 1902 and of the Territory of New Guinea (formerly German New Guinea) in 1920. The two were unified as the Territory of Papua and New Guinea in 1949 and gained independence from Australia in 1975.
