Prime Minister before election James Scullin Labor Subsequent Prime Minister Joseph Lyons United Australia

The incumbent first-term Australian Labor Party (ALP) government led by Prime Minister James Scullin was defeated in a landslide by the United Australia Party (UAP) led by Joseph Lyons. As of 2024, this is the last time that a sitting government at federal level has been defeated after a single term.

The election was held at a time of great social and political upheaval, coming at the peak of the Great Depression in Australia. The UAP had only been formed a few months before the election, when Lyons and a few ALP dissidents joined forces with the Nationalist Party and the Australian Party. Although it was dominated by former Nationalists, Lyons became the merged party's leader, with Nationalist leader John Latham as his deputy.

Scullin's position eroded further when five left-wing Labor MPs from New South Wales who supported NSW Premier Jack Lang broke away and moved to the crossbenches in protest of Scullin's economic policy, reducing Scullin to a minority government. Late in 1931, they supported a UAP no-confidence motion and brought down the government. The two Labor factions were decimated; massive vote-splitting left them with only 18 seats between them (14 for the official ALP and four for the Langites).

Prior to the election, it was assumed that the Country Party, led by Earle Page, would hold the balance of power, and Page tentatively agreed to support the UAP if that were the case. The two parties campaigned separately and stood candidates against each other in the House of Representatives, but ran joint tickets in Senate. However, the UAP came up four seats short of a majority. The five MPs from the Emergency Committee of South Australia, which contested the election in that state in place of the UAP and Country Party, joined the UAP party room, giving the UAP enough numbers to form a majority government by two seats. Page was still willing to form a coalition with the Country Party, but negotiations broke down and Lyons decided the UAP would govern by itself. As a result, the First Lyons Ministry was composed solely of UAP members.

Labor spent the next 10 years in opposition; it did not return to power until 1941.

The election was dominated by the Great Depression in Australia, which was at its height. As the Labor government had come to office two days before the Wall Street Crash of 1929, it was seen as being responsible for many of the economic and social problems Australia faced, which sparked the historic Australian Labor Party split of 1931 in which Lyons and four other Labor dissidents crossed the floor to the opposition, ultimately merging into the UAP. Although the UAP was seen as an upper- and middle-class conservative party, the presence of ex-Labor MPs allowed the party to project an image of national unity.

By the time the writs were issued, official Labor and Lang Labor were in open warfare, making a UAP victory all but certain. Due to the massive vote splitting brought on by a large number of three-cornered contests, Labor tallied its lowest primary vote since Federation, while the two Labor factions, official Labor and Lang Labor, won only 18 seats between them, with official Labor losing a record 32 seats on a massive 15.2% swing to the UAP.

The two Labor factions did not reunite until 1936.
