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.
Australian Senate committees
The most important and high profile of the committees are the pairs of standing committees. These each have six members. The chairman of each legislation committee is chosen from amongst the government members, the deputy chair from amongst non-government members. The reverse is the case for the references committees. Because the chair has a casting vote in the event of a committee vote being tied, the government effectively controls the legislation committees, while the non-government parties control the references committees.
