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, with executive powers delegated by constitutional convention to the Australian head of government, the Prime Minister of Australia.
1975 Australian constitutional crisis
Gough Whitlam's Labor government was elected in 1972 after 23 years of rule by a coalition formed by the Liberal and Country parties. The ALP Government enjoyed a nine-seat majority in the House of Representatives, but did not control the Senate. In accordance with pre-election promises, it instituted a large number of policy changes, and offered much legislation. The Opposition, which still controlled the Senate, allowed some Government bills to pass the Senate, and blocked others.
