 Section 14 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.The section also requires that electorates be apportioned among the states in proportion to their respective populations; provided that each original state has at least 5 members in the House of Representatives, a provision that has given Tasmania higher representation than its population would justify.There are also three electorates in the Australian Capital Territory and two in the Northern Territory.
