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.
Lame duck (politics)
In Australia, regardless of when the election is held, the Senate (upper house) sits from July 1 following the election to June 30 six years later, while the newly elected members of the House of Representatives (lower house) take their seats immediately after an election. A Senate that is destined to lose its majority as a result of such a change is called a "lame-duck Senate" and often attracts criticism if it blocks Government measures introduced in the House of Representatives.
