Australia has [[preferential voting]], which is designed to ensure that the candidates with the most support get into office, rather than the candidate with the most primary votes. So if three candidates, A, B, and C, get 40%, 35%, and 25% of the votes respectively (so no candidate has more than 50% of the votes), then the second preference of the voters who voted for C are distributed to the remaining candidates. The result might be that A ends up with 45% of the votes, and B with 55%, indicating that 55% of the voters prefer candidate B over A.

One consequence of this voting system is that it encourages a multiplicity of parties and even independent candidates. There have been times when the balance of power has been held my minor parties or independent individuals.

There is no limit on the time a person can be a Member of Parliament (MP) (elected, notionally, for 3 years, but the timing of elections is decided by the Prime Minister) or a Senator (elected for two cycles of the House of representatives.) The Prime Minister is normally a member of the House of Representatives, and the tenure is not limited by statute. (John Gorton was a Senator when appointed leader of his party. He immediately resigned from the Senate and stood for election to the House of Representatives.)
