The 45th Parliament of Australia was a meeting of the legislative branch of the Australian federal government, composed of the Australian Senate and the Australian House of Representatives. It met in Canberra from 30 August 2016 to 4 April 2019. 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. During the term of the parliament, the government slipped into minority due to defections and by-elections. The leadership of the government also changed during the parliament, when Scott Morrison replaced Turnbull as Liberal Leader and Prime Minister in August 2018. The 45th Parliament was officially prorogued by the Governor-General Sir Peter Cosgrove at 8:29 a.m. on 11 April 2019, and the House of Representatives dissolved at 8:30 a.m.
