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.
President of the Senate
The President of the Australian Senate is a senator, traditionally a member of the governing party or coalition, elected by the Senate at the beginning of each parliament as the first item of business. They are assisted by a Deputy President who is traditionally a member of the largest opposition party. The current president is Scott Ryan, a Liberal senator from Victoria, who has held the office since 13 November 2017.
