Context paragraphs:
Electoral district of Murray (South Australia): Murray is a defunct electoral district that elected members to the House of Assembly, the lower house of the bicameral legislature of the Australian state of South Australia.  The electorate, incorporating part of the River Murray, was rural in nature, with Mannum the only large town within its boundaries.  From its establishment to the 1938 state election, Murray was a three-member electorate, but was made a single-member electorate afterwards, as part of a system of electoral malapportionment known as the "Playmander".  In both incarnations it elected candidates from both major parties as marginal and safe seat holders at various times.  If just 21 LCL votes were Labor votes in Murray at the 1968 election, Labor would have formed majority government.  Murray was one of two gains in 1968 that put the LCL in office.  The electorate was abolished prior to the 1985 election, with its territory now forming part of the districts of Hammond, Kavel, and Schubert.  In total, 24 people represented Murray between 1902 and 1985, with its most notable member being Thomas Playford IV, who later served as Premier of South Australia.

Electoral district of Queanbeyan: Queanbeyan was an electoral district of the Legislative Assembly in the Australian state of New South Wales from 1859 to 1913, in the Queanbeyan area.

It was merged with the electoral district of Monaro in 1913, when much of its former territory had been absorbed in the Australian Capital Territory.

Electoral district of Kaurna: Kaurna is an electoral district of the House of Assembly in the Australian state of South Australia.

It is one of only two state districts named after South Australia's indigenous people (the other being the Electoral district of Narungga).

Electoral district of Broken Hill: Broken Hill was an electoral district of the Legislative Assembly in the Australian state of New South Wales.  From 1894 to 1913, the Broken Hill district was covered by the electoral districts of "Broken Hill", Willyama and Sturt.  In the 1912 redistribution, the electoral district of "Broken Hill" was abolished and absorbed into "Willyama" and "Sturt".  In 1920, "Willyama", "Sturt" and the electoral district of Cobar were combined to create a three-member "Sturt".  In 1927, single-member electorates were recreated and the city of Broken Hill was split between "Sturt" and Murray.  From 1932, the city of Broken Hill was split between "Sturt" and Cobar.  In 1968 "Sturt" was renamed Broken Hill and included all of the city of Broken Hill.  In 1999, it was merged with part of "Murray" and renamed the electoral district of Murray-Darling.
