query: When was the Australian government formed?
passage: Government of Australia
The Commonwealth of Australia was formed in 1901 as a result of an agreement among six self-governing British colonies, which became the six states. The terms of this contract are embodied in the Australian Constitution, which was drawn up at a Constitutional Convention and ratified by the people of the colonies at referendums. The Australian head of state is the Queen of Australia who is represented by the Governor-General of Australia,[1][2][3][4][5] with executive powers delegated by constitutional convention to the Australian head of government, the Prime Minister of Australia.
passage: Federalism
On the 1st of January 1901 the nation-state of Australia officially came into existence as a federation. The Australian continent was colonised by the United Kingdom in 1788, which subsequently established six, eventually self-governing, colonies there. In the 1890s the governments of these colonies all held referendums on becoming the unified, self-governing "Commonwealth of Australia" within the British Empire. When all the colonies voted in favour of federation, the Federation of Australia commenced, resulting in the establishment of the Commonwealth of Australia in 1901. The model of Australian federalism adheres closely to the original model of the United States of America, although it does so through a parliamentary Westminster system rather than a presidential system.
