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).
President of the Senate (Australia)
The position of President of the Senate has been disproportionately held by Senators representing the least populous states and territories. There have been 25 presidents of the Senate since 1901. Of these 15 have come from the least populous states (Western Australia, South Australia and Tasmania) or the Australian Capital Territory, and 10 have come from the three most populous states (New South Wales, Victoria and Queensland). All senate presidents have been members of major parties, though not necessarily the governing party.
