Redistribution (Australia)
Section 24 of the Constitution of Australia requires that the total number of members of the Australian House of Representatives shall be "as nearly as practicable" twice as many as the number of members of the Australian Senate. There is presently a total of 76 senators: 12 senators from each of the six states and two from each of the two autonomous internal territories (the Australian Capital Territory and the Northern Territory). There are 150 members of the Australian House of Representatives.
List of whips in the Australian Senate
The Democratic Labour Party (until 2013 the Democratic "Labor" Party) elected its first whip in 1968, when its membership increased from two to four. The party continued to do so until 1974, when the party lost all its seats at the double dissolution election. The party re-entered the Senate following the 2010 election, but did not have a whip as it only had one senator, who left the party in 2014.
The Palmer United Party won three Senate seats at the 2013 election, the new senators taking their seats on 1 July 2014. Two of the three had left within a year, but the remaining senator retained the position of whip until his defeat in 2016.
