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.
Parliaments of the Australian states and territories
The Parliament of South Australia is a bicameral legislature comprising the South Australian Legislative Council and the House of Assembly. According to the South Australian Constitution, unlike the Federal Parliament, and the parliaments of the other states and territories of Australia, neither the Sovereign nor the Governor is considered to be a part of the South Australian Parliament. The Legislative Council has 22 members, elected for eight-year terms by proportional voting with half the members facing re-election every four years, and the House of Assembly which has 47 members, elected for four-year terms from single-member constituencies, using preferential voting. Voting is compulsory.
