Editing Dominant-party system (section)

===Oceania===
*'''{{flag|Australia}}:''' The [[Liberal Party of Australia|Liberal Party]] (generally in a near-permanent [[Coalition (Australia)|Coalition]] with the [[National Party of Australia|National Party]]) held power federally from 1949 to 1972 and from 1975 to 1983 (31 out of 34 years). After the expiry of the 46th Parliament in 2022, the [[Coalition (Australia)|Liberal-National Coalition]] held power for 20 out of the 26 years between 1996 and 2022. Overall from 1949 to 2022, the Liberal Party held power for 52 out of 73 years. The longest-serving [[Prime Minister of Australia|Prime Minister]] was [[Robert Menzies]], who served from 1939 to 1941 (2 years) as a member of the [[United Australia Party]], and from 1949 to 1966 (16 years) as leader of the Liberal Party. The second longest-serving was [[John Howard]] (Liberal Party), who was Prime Minister from 1996-2007 (11 years).
**'''{{flag|Northern Territory}}:''' The [[Country Liberal Party]] held power from the granting of self-government in 1978 to 2001 (23 years).
**'''{{flag|New South Wales}}:''' The [[Australian Labor Party (New South Wales Branch)|Labor Party]] held power from 1941 to 1965 (24 years), and from 1976 to 1988 and 1995 to 2011 (28 out of 35 years) – in total 52 out of 70 years from 1941 to 2011.
**'''{{flag|Queensland}}:''' The [[Australian Labor Party (Queensland Branch)|Labor Party]] held power from 1915 to 1929 and from 1932 to 1957 (39 out of 42 years). The [[National Party of Australia – Queensland|National Party]] then held power from 1957 to 1989 (32 years) with and without the [[Liberal Party of Australia (Queensland Division)|Liberal Party]]. These were facilitated by a Labor-designed malapportionment that favoured rural districts. The National Party under [[Joh Bjelke-Petersen]] increased the malapportionment with the [[Bjelkemander]], allowing them to rule alone without the Liberals, and used the police to suppress dissent and opposition from Labor. The National Party dominance was ended by a corruption inquiry, Bjelke-Petersen was forced to resign in disgrace, and police and politicians were charged with crimes. Since 1989, Labor has held government aside from a National Party government (1996 to 1998) and Liberal-National Party government (2012 to 2015) (28 years of Labor government out of 33 years).
**'''{{flag|South Australia}}:''' The [[Liberal Party of Australia (South Australian Division)|Liberal and Country League]] held power from 1933 to 1965 (32 years) using the [[playmander]]. The [[Australian Labor Party (South Australian Branch)|Labor Party]] held power from 1970 to 1979, from 1982 to 1993 and from 2002 to 2018 (26 out of 38 years).
**'''{{flag|Tasmania}}:''' The [[Australian Labor Party (Tasmanian Branch)|Labor Party]] held power from 1934 to 1969 and from 1972 to 1982 (45 out of 48 years), from 1989 to 1992, and from 1998 to 2014 (16 years) – in total 64 out of 80 years from 1934 to 2014.
**'''{{flag|Victoria}}:''' The [[National Citizens' Reform League]] (1902–1909), the [[Liberal Party (Australia, 1909)|Deakinite Liberal Party]] (1909–1917) and the [[Nationalist Party (Australia)|Nationalist Party]] (1917–1924) consecutively held power from 1902 to 1924 (22 years). The [[National Party of Australia – Victoria|Country Party]] then ruled from 1924 to 1927 (3 years), followed by the Nationalist Party from 1928 to 1929 (1 year) in a [[Coalition (Australia)#Victoria|coalition]]. The Country Party and the [[United Australia Party]] (later as the [[Liberal Party of Australia (Victorian Division)|Liberal and Country Party]]) held power with and without a coalition from 1932 to 1945 (13 years) and 1947 to 1952 (5 years). The Liberal Party then held power from 1955 to 1982 (27 years). In total, centre-right governments ruled 71 out of 80 years from 1902 to 1982.
