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.
Leader of the Opposition (South Australia)
Before the 1890s when there was no formal party system in South Australia, MPs tended to have historical liberal or conservative beliefs. The liberals dominated government from the 1893 election to 1905 election with Labor support, with the conservatives mostly in opposition. Labor took government with the support of eight dissident liberals in 1905 when Labor won the most seats for the first time. The rise of Labor saw non-Labor politics start to merge into various party incarnations. The two independent conservative parties, the Australasian National League (formerly National Defence League) and the Farmers and Producers Political Union merged with the Liberal and Democratic Union to become the Liberal Union in 1910. Labor formed South Australia's first majority government after winning the 1910 state election, triggering the merger. The 1910 election came two weeks after federal Labor formed Australia's first elected majority government at the 1910 federal election.
