Parliament of Australia
From 1901 to 1949, the House consisted of either 74 or 75 members (the Senate had 36). Between 1949 and 1984, it had between 121 and 127 members (the Senate had 60 until 1975, when it increased to 64). In 1977, the High Court ordered that the size of the House be reduced from 127 to 124 members to comply with the nexus provision. In 1984, both the Senate and the House were enlarged; since then the House has had between 148 and 150 members (the Senate has 76).
Members of the Australian Senate, 1987–1990
In accordance with section 13 of the Constitution, following a double dissolution of Parliament, the terms for Senators commence on 1 July preceding the election – i.e., on 1 July 1987. The Senate decides which senators were allocated the full six-year terms ending on 30 June 1993 and which senators were allocated three-year terms ending on 30 June 1990. In 1983 the "Commonwealth Electoral Act" 1918 had been amended to include provision for a recount of ballot papers to determine the senators to get the long term vacancies. This was the result of a unanimous recommendation from the Joint Select Committee on Electoral Reform. Despite the unanimous recommendation for reform, Labor and the Democrats maintained the previous system where the first six senators elected in each state were allocated the full six-year terms ending on 30 June 1993 while the other half were allocated three-year terms ending on 30 June 1990. The effect of this system was that Democrat Senators Paul McLean and Janet Powell got a long term instead of National Senators David Brownhill and Julian McGauran. There was no net effect on Labor and Liberal in that in South Australia, Labor Senator Graham Maguire got a long term instead of Liberal Senator Robert Hill, while in Queensland, Liberal Senator Warwick Parer got a long term instead of Labor Senator Gerry Jones. Senators took their seats immediately following the election on 11 July 1987. The four territory senators were elected in July 1987 and their terms ended at the dissolution of the House of Representatives, which was March 1990.
