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.
Father of the Australian Senate
The first Senate was elected on 29 and 30 March 1901. Despite the different election dates, all the members elected to that first Parliament were considered to have had equal seniority. It follows that there could not be a "longest-serving Senator" until only one Senator from the first Parliament was still serving. That occurred on 14 September 1923 with the death of Hon Edward Millen, leaving Sir George Pearce as the sole longest-serving Senator, and thus the first sole Father of the Senate.
