Australian Senate

The Australian Senate is one of the two houses of the Parliament of Australia. It is also known as the "upper house".

Although the House of Representatives (the "lower house") elects the Prime Minister and thus forms Government, the two houses have almost equal legislative power. The only exception is that the Senate cannot pass appropriation bills or impose taxation.

Rather than being modelled after the House of Lords the Australian Senate was modelled after the United States Senate and was intended to give small rural states added voice in a Federal legislature.

If the Senate repeatedly refuses to pass legislation initated in the lower house, the Government must either abandon the bill, or call a double dissolution (election for both houses of Parliament) and attempt to pass the bill at a subsequent joint sitting of the two houses.

The voting system for the Senate has changed twice since it was created. The original arrangement was a block voting mechanism [OK, but what does that mean?]. In 1919, this was ammended to allow for preferential voting.

The block voting model tended to grant landslide majorities very easily. In 1946, the Australian Labor Party government won 30 out of the 33 Senate seats. In 1948, partially in response to this extreme situation, they introduced proportional representation in the Senate.

In some respects, the Senate is quite unrepresentative; Tasmania, with a population of 450,000, elects the same number of Senators as New South Wales, which has a population of 6 million. Paul Keating called it an "unrepresentative swill". But the proportional election system within each state ensures that Senate is much more diverse than the lower house, which is basically a two party body. Because of this the Senate frequently functions as a house of review.

The size of the Senate has changed over the years. The Australian Constitution requires that the Senate be as near as possible to half of the size of the House of Representatives, and it has therefore grown periodically. Currently, each of the six States of Australia has 12 Senators, while the Northern Territory and the Australian Capital Territory have two each. Normally, half of the Senate is contested at each election, for terms of up to six years, but during a double dissolution, every seat faces re-election.

Significant events in the history of the Senate include its role in the downfall of the Whitlam Government, and the Howard Government's bribing of Senator Mal Colston to obtain a majority, enabling the passage of a great deal of controversial legisaltion.

Parties which currently have representation in the Senate: Australian Democrats, Australian Greens, Australian Labor Party, Liberal Party of Australia, National Party of Australia, One Nation.

Parties which have been represented in the past: Democratic Labor Party, Nuclear Disarmament Party... [free traders, protectionists, early incarnations of the liberal & national parites..]
