What was Federation in Australian history?

Federation in Australian history is the process by which the six Australian colonies joined to form the Commonwealth of Australia on 1 January 1901. The process took about a decade from 1889 to 1901 and involved constitutional conventions, referendums in each colony, and the passage of the Commonwealth of Australia Constitution Act 1900 by the British Parliament.

Several factors drove Federation. Defence concerns: European powers (France, Germany, Russia) were showing growing interest in the Pacific. Economic interests: customs duties between colonies hindered trade and a unified national market promised gains. Immigration policy: the colonies wanted consistent controls, particularly to enforce restrictions on non-European migration. National identity: a growing sense of Australian nationhood, reinforced by sport, culture, and the shared experience of the 1890s depression, supported federation.

The path began with Henry Parkes' Tenterfield Oration on 24 October 1889, in which the NSW Premier called for a national convention. The National Australasian Convention met in Sydney in 1891 with 45 delegates from the Australian and New Zealand colonies. The 1891 draft stalled but renewed momentum came at the Australasian Federation Convention of 1897 to 1898 in Adelaide, Sydney, and Melbourne, with ten delegates from each Australian colony (Queensland did not participate). The final draft was put to colony referendums between 1898 and 1900.

All six colonies voted Yes by July 1900. The British Parliament passed the Commonwealth of Australia Constitution Act 1900 on 5 July 1900, with Queen Victoria giving royal assent on 9 July 1900. The Commonwealth was proclaimed at Centennial Park in Sydney on 1 January 1901 before a crowd of more than 60,000. Lord Hopetoun was sworn in as the first Governor-General. Edmund Barton (NSW Free Trade) became the first Prime Minister. Australians voted at the first federal election on 29 to 30 March 1901, and the first Parliament was opened at the Royal Exhibition Building in Melbourne on 9 May 1901.
