Opposition (Australia) in the context of "2010 Australian federal election"

The Liberal Party of Australia (LP) is the prominent centre-right to right-wing political party in Australia. It is considered one of the two major parties in Australian politics, the other being the Australian Labor Party (ALP). The Liberal Party was founded in 1944 as the successor to the United Australia Party. Historically the most electorally successful party in Australia, the Liberal Party is now in opposition at a federal level, although it presently holds government in the Northern Territory, Queensland and Tasmania at a state (sub-national) level.

The Liberal Party is the largest partner in a centre-right grouping known in Australian politics as the Coalition, accompanied by the regional-based National Party, which is typically focussed on issues pertinent to regional Australia. The Liberal Party last governed Australia, in coalition with the Nationals, between 2013 and 2022, forming the Abbott (2013–2015), Turnbull (2015–2018) and Morrison (2018–2022) governments. The Coalition has been suspended on occasion throughout the 20th and 21st centuries, though as of 2025 the two parties form a shadow ministry under the leadership of Sussan Ley.

The 1901 Australian federal election for the inaugural Parliament of Australia was held in Australia on Friday 29 March and Saturday 30 March 1901. The elections followed Federation and the establishment of the Commonwealth of Australia on 1 January 1901. All 75 seats in the Australian House of Representatives, six of which were uncontested, as well as all 36 seats in the Australian Senate, were up for election.

After the initial confusion of the Hopetoun Blunder, the first Prime Minister of Australia, Edmund Barton, went into the inaugural 1901 federal election as the appointed head of a Protectionist Party caretaker government. While the Protectionists came first on seats, they fell short of a majority. The incumbent government remained in office with the parliamentary support of the Labour Party, who held the balance of power, while the Free Trade Party formed the opposition. A few months prior to the 1903 election, Barton resigned to become a founding member of the High Court of Australia, and was replaced by Alfred Deakin.

In Australian federal politics, the Leader of the Opposition is an elected member of parliament (MP) in the Australian House of Representatives who leads the opposition. The Leader of the Opposition, by convention, is the leader of the largest political party in the House of Representatives that is not in government.

When in parliament, the opposition leader sits on the left-hand side of the centre table, in front of the opposition and opposite the prime minister. The opposition leader is elected by their party according to its rules. A new leader of the opposition may be elected when the incumbent dies, resigns, or is challenged for the leadership.
