Australian Senate
While there is no constitutional requirement for the election of Senators to take place at the same time as those for members of the House of Representatives, the government usually synchronises the dates of elections for the Senate and House of Representatives. However, because their terms do not coincide, the incoming Parliament will for some time comprise the new House of Representatives and the old Senate, except for the senators representing the territories, until the new senators start their term on the next 1 July.
