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.
District of Columbia voting rights
In the Parliament of Australia, the Australian Capital Territory (ACT) has seats in both the House of Representatives and Senate, although it was not until 1974 that residents of the ACT were able to vote for the latter. Unlike a state, which elects twelve Senators, the ACT only elects two.
