List of Australian federal elections

This article provides a summary of results for the general elections to the Australian House of Representatives and Senate, respectively the lower and upper houses of Australia's federal bicameral legislative body, the Parliament of Australia. The number of seats has increased steadily over time, from 111 for the first election, to the current total of 226. The current federal government structure was established in 1900 by the Commonwealth of Australia Constitution Act, 1900.

Two groups have dominated politics in Australia: Labor and the Coalition, composed of the Liberal Party and the National Party. Since the foundation of the Liberal Party in 1944, these two groups have formed every government.

Although government has been a two-party system, the Senate has a multi-party tradition, beginning with the 1955 election, where one DLP candidate was elected (under the ALP-AC banner). Although the DLP ceased to be a force after Gough Whitlam took power in 1972, the Liberal Movement and its successor the Australian Democrats carved out their own niche. In the 1980s the NDP briefly gained election, and in the 1990s the Greens first joined the Senate, while more recently One Nation and Family First did the same.
