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 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 South Australia is a bicameral legislature comprising the South Australian Legislative Council and the House of Assembly. According to the South Australian Constitution, unlike the Federal Parliament, and the parliaments of the other states and territories of Australia, neither the Sovereign nor the Governor is considered to be a part of the South Australian Parliament. The Legislative Council has 22 members, elected for eight-year terms by proportional voting with half the members facing re-election every four years, and the House of Assembly which has 47 members, elected for four-year terms from single-member constituencies, using preferential voting. Voting is compulsory.
