12 of Australia's 28 prime ministers have represented the Australian Labor Party.

The first was John Christian Watson in 1904. He was followed by Andrew Fisher in 1908, who formed the first majority Labor government in 1910 and the first majority government since Federation. After his third term, Fisher was succeeded by William Morris Hughes, who subsequently split the party over conscription and joined with his conservative opponents. James Scullin won office in 1929 and was followed by John Curtin in 1941, Frank Forde in 1945 and Ben Chifley in 1945. Following a long period in opposition, Gough Whitlam won office in 1972 and was followed by Bob Hawke in 1983, Paul Keating in 1991, Kevin Rudd in 2007 and Julia Gillard in 2010.

Frank Forde was prime minister for 8 days in 1945, following the death of John Curtin. Forde was deputy leader of the ALP but the party chose Ben Chifley to be the new leader.

Fadden was PM for 1 month, 9 days, McEwen for 23 days and Page for 20 days.

Menzies. He contested 9 elections as leader of the United Australia Party (1940) and the Liberal Party (1946, 1949, 1951, 1954, 1955, 1958, 1961 and 1963). He won 8 of these - 1946 was his only defeat.

His 7 consecutive victories between 1949 and 1963 is unlikely ever to be matched.

Australia's 4th prime minister, George Reid, was the first to die, in 1918.

He was followed by Alfred Deakin in 1919 and Edmund Barton in 1920. Watson died in 1941.

4. George Reid (1910-16), Andrew Fisher (1916-20), Joseph Cook (1821-27) and Stanley Melbourne Bruce (1933-45) all served as High Commissioner to London after first serving as prime minister.

Gough Whitlam holds both records. He was 98 when he died in October 2014. He had lived for 38 years and 11 months after being dismissed on November 11, 1975.

4. Alfred Deakin, Andrew Fisher, Robert Menzies and Kevin Rudd all held office more than once in non-consecutive terms. Deakin and Fisher each had 3 terms, whilst Menzies and Rudd had 2.

Malcolm Fraser. In 1975, Fraser's Liberal-National coalition won 91 of the 127 seats in the House of Representatives - 71.65%. Fraser had been Opposition Leader but fought the election as prime minister following the Governor-General's dismissal of Gough Whitlam on November 11.

8. Joseph Cook (1913), James Scullin (1929), Joseph Lyons (1931), Gough Whitlam (1972), Bob Hawke (1983), John Howard (1996), Kevin Rudd (2007) and Tony Abbott (2013) all led their parties to victory at general elections and became prime minister for the first time.

Stanley Melbourne Bruce became PM after the 1922 election, but he had not led his party during the election. When the Nationalists failed to secure an outright majority, the Country Party insisted on Hughes's replacement as their price for supporting the government.

Menzies led the coalition to victory in 1949 but he had previously become PM following the death of Lyons.

12. Most of Australia's 28 PMs were born in the 19th century.

Those born in the 20th century were: John McEwen (1900), William McMahon (1908), Harold Holt (1908), John Gorton (1911), Gough Whitlam (1916), Bob Hawke (1929), Malcolm Fraser (1930), John Howard (1939), Paul Keating (1944), Kevin Rudd (1957), Tony Abbott (1957) and Julia Gillard (1961).
