State and territory elections:

• 1989 Queensland state election – Wayne Goss led the Labor Party to a historic landslide victory over the Country Party (later known as the National Party) led by Russell Cooper. The Country Party had been in power for 32 consecutive years; from 1957–1983 the Country Party ruled as the senior partner in a coalition with the Liberal Party, and then from 1983–1989 the Country Party ruled alone. Much of this 32 year period was under 7-term Premier Joh Bjelke-Petersen. In the election, Labor won 50.3% of the primary vote and 53.8% of the two-party preferred (TPP) vote, and 54 out of 89 seats, despite a system of malapportionment which was designed to keep the Country Party in power.
• 1993 South Australian state election – The Liberal Party, led by Dean Brown, defeated the incumbent Labor government, led by Lynn Arnold. The Liberals won 37 of the 47 seats in the House of Assembly (a net increase of 15) and had a two-party-preferred vote (TPP) of 60.91%. This is still the largest majority government in South Australian history.
• 2002 Victorian state election – The Labor Party, led by Steve Bracks, won 62 of the 88 seats in the Legislative Assembly and a two-party-preferred vote (TPP) of 57.78%, a net increase of 20 seats. This is easily the largest majority won by Labor in Victorian history and one of Labor's best performances at a state level in Australia, as well as being only the third time a Labor government has been re-elected in Victoria. The Liberal-National Coalition was broken at the election, therefore the Liberals and the Nationals contested separately.
• 2011 New South Wales state election – Barry O'Farrell led the Liberal–National Coalition to win 69 out of the 93 seats in the lower house, defeating Kristina Keneally's Labor government. The Coalition had a primary vote of 51.14% and a TPP of 64.22%.
• 2012 Queensland state election – Campbell Newman led the Liberal National Party (formed from a joining of the National Party and Liberal Party in Queensland) to win 78 seats out of the 89 seats in parliament, defeating Anna Bligh's Labor government. The Liberal National Party had a primary vote of 49.66% and a TPP vote of 62.8%.
• 2014 Tasmanian state election – The Liberal Party, led by Will Hodgman, won a landslide victory, defeating the incumbent Labor government, led by Premier Lara Giddings.[4] This ended 16 years of Labor government in Tasmania. The Liberal Party won 15 of the 25 seats and 51.22% of the primary vote, while Labor won seven seats and 27.33% of the primary vote and the Greens won three seats and 13.83% of the primary vote. There was also a 12.83% swing to the Liberal Party.
• 2018 Victorian state election – The first-term incumbent Labor government, led by Daniel Andrews, was re-elected in a landslide victory, winning 55 out of 88 seats in the lower house, an increase of eight seats from the previous election in 2014. The Coalition suffered an 11-seat swing against it, and won 27 seats. With a primary vote of 42.86% and TPP of 57.30%, it tied Victorian Labor's second-best showing at the state level.
• 2021 Western Australian state election – Mark McGowan led the Labor Party to win 53 out of the 59 seats in the lower house. The Labor Party had a primary vote of 59.92% and a two-party-preferred vote of 69.68%. The National Party won 4 seats and the Liberal Party won 2 seats, making the National Party the official opposition, the first time they had held this status since the 1940s. To date, the election is the most decisive result at any Australian state or federal election since Federation, in terms of both percentage of lower house seats controlled by the governing party (89.8%) and two-party preferred margin.[5][6]

Federal elections:

• 1931 Australian federal election – Joseph Lyons, leader of the United Australia Party and of the Coalition (which also consisted of the Country Party) won a landslide victory over the single-term Labor government of Prime Minister James Scullin. This was the last time that a government has only served a single term at the federal level.
• 1943 Australian federal election – The incumbent Labor government led by war-time PM John Curtin won a landslide victory over the Coalition led by Country Party leader Arthur Fadden.
• 1966 Australian federal election – PM Harold Holt leads his incumbent Coalition government (now consisting of the Liberal Party and Country Party) to a landslide victory over the Labor Opposition, increasing their majority by a further 10 seats, the Liberals almost won enough seats to govern in their own right without the Country Party.
• 1975 Australian federal election – Coalition led by Liberal Party's Malcolm Fraser won a landslide victory over Labor government led by PM Gough Whitlam Winning 91 out of 127 Seats.
• 1983 Australian federal election – Labor led by Bob Hawke wins landslide victory (75 of 125 seats, an increase of 24, and 49.48% of the primary vote) over Coalition government led by PM Malcolm Fraser
• 1996 Australian federal election – Coalition led by Liberal Party's John Howard wins landslide victory over Labor government led by PM Paul Keating, ending 13 consecutive years of Labor government. The Coalition as a whole wins 94 of 148 seats, winning the largest majority government to date in Australian history. The Liberal Party alone wins 75 seats – enough to govern in its own right, however they choose to include the National Party (formerly the Country Party) and the Country Liberal Party in the Coalition government.
• 2007 Australian federal election – Labor led by Kevin Rudd wins landslide victory over Coalition government led by PM John Howard who had been in office for 11 consecutive years. Not only did the Coalition lose government but John Howard lost his seat.
• 2013 Australian federal election – Coalition led by Liberal Party's Tony Abbott wins landslide victory over Labor government led by PM Kevin Rudd, winning 90 out of 150 seats.

Notable non-landslides:

• The 1972 Australian federal election resulted in a victory for Labor under Gough Whitlam, ending 23 consecutive years of Coalition government. However, the result was not a landslide with Labor only winning 67 of 125 seats.
• The 2019 Australian federal election, whilst polls showing a Labor victory, was won by the Coalition. The elected Prime Minister, Scott Morrison, became the first to serve a full term in office (serving one and a half terms) since John Howard. Scott Morrison famously used the phrase "the quiet Australians" in a speech following his victory.
• The 2022 Australian federal election resulted in a victory for Labor, ending 9 years of Coalition government. It was a historic loss for the Coalition, which was reduced to just 58 seats of 151 seats, their worst result in 70 years. However, Labor only won a slim majority, 77 of 151 seats. This is because the Coalition losses were split between Labor, teal independents and the Greens, while Labor themselves also lost seats to independents and Greens.

Thus, landslide elections at that time were defined in an identical fashion, i.e. where one party got an overwhelming majority of the seats. Since 1996, New Zealand has used the mixed member proportional system as in Germany, making landslides much less likely.[13]

Ramon Magsaysay (light green)'s 1953 landslide victory.

In 1941, the Nacionalista Party won the presidency, vice presidency, all seats in the Senate, and all but 3 seats in the House of Representatives. This was the biggest landslide in Philippine history. The legislators won't serve until 1945 though, due to World War II.

Starting in 1987, the Philippines evolved into a multi-party system, and coupled with the introduction of party-list elections in 1998, no party was able to win a landslide, much less a majority of seats, in the House of Representatives since then. This has also meant that no presidential and vice presidential election winner won a majority of votes, although, in 1998, the winners were described as having landslide victories, despite winning less than a majority of votes, due to large winning margins. Senatorial landslides are more possible though in midterm elections, as voters are usually presented with two distinct choices. The 2022 presidential election was the first landslide since 1987.

In UK General Elections, a landslide victory involves winning a large majority in parliament and often goes with a large swing from one party to another as well. Landslide victories have usually occurred after a long period of government from one particular party and a change in the popular mood. In the past a majority of over 100 was regarded as the technical hurdle to be defined as a landslide, as that allows the government freedom to easily enact its policies in parliament. In more recent times, the label 'landslide' has been applied in numerous press articles to victories which would not previously have been regarded as such, for example the Conservative Party majority of 80 in 2019. Its current usage is more as political commentary rather than technical definition and is a reflection of the strength of the party's ability to put its programme through parliament.[20][21][22][23]

The largest landslide by any single party in the UK parliament, since universal suffrage was introduced, was the majority of 179 won by Tony Blair's Labour Party in 1997.
