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).
Parliaments of the Australian states and territories
The Parliament of Western Australia is a bicameral legislature comprising the Western Australian Legislative Council, the Legislative Assembly and the Queen, represented by the Governor of Western Australia. The Legislative Council has 36 members, elected for fixed four-year terms from six multi-member electoral regions by "community of interest" —3 metropolitan and 3 rural—each electing 6 members by proportional voting. There is a significant malapportionment in the Legislative Council in favour of rural regions. The Legislative Assembly has 59 members, elected for fixed four-year terms from single-member constituencies, using preferential voting. Voting is compulsory, with elections being held every four years on the second Saturday in March, though the term of the Legislative Council does not expire until May after the election.
