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.
Premiers of the Australian states
The Australian states were founded as British colonies, and executive power was held by a Governor (or sometimes a Lieutenant-Governor) appointed by the British Government (see Governors of the Australian states). From the 1820s the power of the Governors was gradually transferred to legislative bodies, at first appointed, later partly elected, and finally fully elected. Victoria gained full responsible parliamentary government in 1855, New South Wales, South Australia and Tasmania in 1856, Queensland in 1859 and Western Australia (owing to its much smaller population) in 1890.
