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.
2007 Australian federal election
Labor and the Coalition won 18 seats each in the half-Senate election. The Greens won three seats, with Independent Nick Xenophon being elected on primary votes alone. This took the 76-member Senate total to 37 Coalition, 32 Labor, 5 Green, 1 Family First, and 1 Independent. With a majority being 39 senators, when the new Senate met after 1 July 2008, the balance of power was shared between Xenophon, Family First's Steve Fielding and the five Greens. Xenophon, although reported as left-of-centre, indicated plans to work closely with the renegade National, Senator Barnaby Joyce. If sufficient Coalition senators voted for government legislation, support from the crossbench was not required.
