What was the significance of Federation?

The significance of Federation lies in its creation of the Commonwealth of Australia on 1 January 1901, transforming six separate British colonies into a single nation with a federal Parliament, an executive government, a national high court, a unified customs union, and a shared identity that has developed over the 125-plus years since.

Several specific institutional creations followed federation. The federal Parliament met for the first time on 9 May 1901 in the Royal Exhibition Building in Melbourne, with the new Constitution providing the basis for federal law-making. The first Prime Minister, Edmund Barton, led the first federal government. The High Court of Australia was established in 1903 with three founding Justices. The Commonwealth Public Service was established under the Public Service Act 1902. The Australian Defence Force consolidated the various colonial military forces. A national customs union eliminated inter-colonial tariffs from 1901, with Western Australia maintaining transitional duties for five years.

The political significance extended to specific policy areas. The Commonwealth Franchise Act 1902 gave women the federal vote and the right to stand for Parliament (Australia became the first country to grant both), although the Act also denied the federal vote to Aboriginal, Asian, and African Australians. The Immigration Restriction Act 1901 established the White Australia Policy. The Conciliation and Arbitration Act 1904 established the federal industrial relations system, with the Harvester Judgment of 1907 producing the world-leading minimum wage principle.

Federation also had unintended consequences. The federal structure made some areas of policy difficult to coordinate, with federal-state tensions operating throughout the twentieth century around income tax (rationalised in 1942), education (federal funding from the 1960s), health (Medibank from 1975), the environment, Indigenous affairs, and many other areas. The Constitution's amendment process under section 128 has produced only 8 successful amendments out of 45 referendum questions, making constitutional change difficult. The federation's longer-term significance is the establishment of stable democratic government, the unification of the national economy, the development of Australian identity, and the country's place in international affairs as an independent nation (although the move from dominion to fully independent country took the rest of the twentieth century, with the Australia Acts 1986 completing the transition).
