How do we choose who we want elected into the House of Representatives in comparison to those that we want in the Senate?
Thanks for your question, Kaihla! At a federal election, Australians choose members of parliament to represent their views and interests in the Senate and the House of Representatives.
In the Senate, 12 senators are elected to represent each state and 2 senators are elected to represent each territory. State senators are elected for a period of 6 years using a system of rotation that ensures only half the state senators end their term every 3 years. Territory senators are elected for a period of 3 years at the same time as the members of the House of Representatives.
Senators are elected using a system of proportional voting, designed to allocate seats to candidates in proportion to the votes cast in an election.
There are 150 members elected to the House of Representatives one for each of Australia's 150 electorates. An average of 120,000 voters live in each electorate. Each member is elected using a system of preferential voting, designed to elect a single member with an absolute majority for each electorate.
