Short answer

From colonies to a nation

Before federation, Australia consisted of separate British colonies. On 1 January 1901, six colonies united as the Commonwealth of Australia. Federation created a national government without removing the states.

Earlier European settlement

The First Fleet arrived from Great Britain in 1788 and the colony of New South Wales was established. Later events, including the gold rushes that began in 1851, shaped population, trade and the development of the colonies.

Why federation still matters

Federation explains why Australia has both national and state governments. It also provides the historical setting for the Constitution, Parliament and the distribution of government responsibilities.

  • Federation took place on 1 January 1901.
  • Six colonies joined to form the Commonwealth of Australia.
