Timeline of the expansion of federal powers in Australia

Federalism was adopted, as a constitutional principle, in Australia on 1 January 1901. Relatively few changes have been made to the formal constitution since Australian federation occurred; in practice, however, the Commonwealth government has increasingly assumed a position of pre-eminence in many areas of governance through the acquisition and negotiation of additional powers and responsibilities directly with the Australian states and territories.
