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.
Dominion
Four colonies of Australia had enjoyed responsible government since 1856: New South Wales, Victoria, Tasmania and South Australia. Queensland had responsible government soon after its founding in 1859 but, because of ongoing financial dependence on Britain, Western Australia became the last Australian colony to attain self-government in 1890. During the 1890s, the colonies voted to unite and in 1901 they were federated under the British Crown as the Commonwealth of Australia by the "Commonwealth of Australia Constitution Act". The Constitution of Australia had been drafted in Australia and approved by popular consent. Thus Australia is one of the few countries established by a popular vote. Under the Balfour Declaration of 1926, the federal government was regarded as coequal with (and not subordinate to) the British and other Dominion governments, and this was given formal legal recognition in 1942 (when the "Statute of Westminster" was retroactively adopted to the commencement of the Second World War 1939). In 1930, the Australian prime minister, James Scullin, reinforced the right of the overseas Dominions to appoint native-born governors-general, when he advised King George V to appoint Sir Isaac Isaacs as his representative in Australia, against the wishes of the opposition and officials in London. The governments of the States (called colonies before 1901) remained under the Commonwealth but retained links to the UK until the passage of the "Australia Act 1986".
