The Australian Parliament is bicameral, which means there are 2 houses—the Senate and the House of Representatives. When reference is made to the people's house, this usually means the House of Representatives. Similarly the Senate is often referred to as the state's house.
There are 151 members elected to the House of Representatives. Each member represents one of Australia's 151 electorates. On average, there are an average of 100 000 voters in each electorate. Representation in the House of Representatives is based on population.
There are 76 senators elected to the Senate—12 senators for each state and 2 for each territory. Representation in the Senate is not determined by population; each state has the same number of senators.
