President of the Senate (Australia)
The position is provided for by Section 17 of the Constitution of Australia. The Senate elects one of its members as president at the start of each new term, or whenever the position is vacant. This is usually—though not necessarily—a member of the party or coalition that holds the most seats in the Senate. The largest party in the Senate is not always the governing party, as government is determined by the House of Representatives. The President of the Senate and the Speaker of the House of Representatives may consequently be from different parties.
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.
