Members of the Australian Senate, 2016–2019
This is a list of members of the Australian Senate following the 2016 double dissolution election on 2 July 2016. All 76 senators were elected due to the election being the result of a double dissolution, and not an ordinary half-senate election. The terms of half of the senators representing each of the six states of Australia were allocated six-year terms ending on 30 June 2022 with the remainder allocated three-year terms ending on 30 June 2019. The terms of senators from the states can only be truncated if another double dissolution election is called. The terms of senators from the Australian Capital Territory and the Northern Territory end on the next dissolution of the House of Representatives.
2019 Australian federal election
The final outcome in the 76-seat Senate took more than four weeks to determine, despite significant voting changes. Earlier in 2016, legislation changed the Senate voting system from a full-preference single transferable vote with group voting tickets to an optional-preferential single transferable vote. The final Senate result was announced on 4 August: Liberal/National Coalition 30 seats (−3), Labor 26 seats (+1), Greens 9 seats (−1), One Nation 4 seats (+4) and Nick Xenophon Team 3 seats (+2). Derryn Hinch won a seat, while Jacqui Lambie, Liberal Democrat David Leyonhjelm and Family First's Bob Day retained their seats. The number of crossbenchers increased by two to a record 20. The Liberal/National Coalition will require at least nine additional votes to reach a Senate majority, an increase of three. As per convention, the government and opposition agreed to support a motion in the parliament that the first six senators elected in each state would serve a six-year term, while the last six elected would serve a three-year term.
