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.
45th Parliament of Australia
The 45th Parliament of Australia is a meeting of the legislative branch of the Australian federal government, composed of the Australian Senate and the Australian House of Representatives. It has been meeting in Canberra from 30 August 2016 to the present. The 2016 general election held on 2 July gave the Coalition of the Liberal and National Parties control of the House, albeit with a slimmer majority than the 44th Parliament, allowing their leader Malcolm Turnbull to stay in office as the 29th Prime Minister of Australia.
