How to vote

You will be given two ballot papers:

  • The green ballot paper is for the House of Representatives

  • The white ballot paper is for the Senate

House of Representatives

The House of Representatives is made up of MPs representing 151 electorates across Australia. There are about the same number of voters in each electorate. You vote for the MP to represent your electorate.

Australia uses a preferential voting system in the House of Representatives.

This means that instead of just voting for one candidate, you should rank candidates in order of how you feel about them.

Find more information about the preferential voting system on this poster.

Candidates for the House of Representatives need at least 50 per cent of the votes to be elected.

If your first choice (the candidate that you marked as number 1) is not elected, your second choice will be counted instead. If your second choice is not elected, your third choice will be counted instead. This continues until one candidate has at least 50 per cent of all votes.

The preferential voting system means that if you vote for a less popular candidate or a smaller party as your first preference, and they do not win, your vote will still be counted towards electing your member. After the election, parties will look at the ‘first preference’ votes to better understand issues that matter to their electorate.

For example – if a large number of voters put number 1 next to Party A, but Party B wins the electorate, the new MP from Party B will still know that a lot of their electorate care about the issues represented by Party A. This may then influence the decisions they make in parliament.

Filling in the ballot paper


Senate

Each State is represented by twelve Senators and each Territory by two Senators.

State Senators are elected for a six-year period. At each normal election, half of the state Senators are elected, meaning you will vote for six Senators if you live in a State. Sometimes there is a “double dissolution election” and every Senator will be elected, meaning you will vote for twelve Senators. For more information about double dissolution elections, visit the AEC website.

Territory Senators are elected for three-year periods. If you live in a Territory, you vote for two Senators at every election.

Australia uses a proportional representation system in the Senate. This means that seats are allocated to candidates according to the number of votes they receive. Candidates need a certain quota of votes to be elected.

Instead of just voting for one candidate, you should rank candidates or parties in order of how you feel about them.

You can vote above-the-line or below-the-line. See the example below.

The way votes are counted in the Senate is complicated and can take a lot of time.

First preference votes (the candidate you marked as number 1) are counted first. Any candidate who has received the quota from these votes is elected.

If they have received more votes than the quota (surplus votes), the second preferences (the candidate marked as number 2) of all their votes will be counted, but at a reduced rate. Other candidates may reach the quota from this and be elected.

If there are still Senate spots left unfilled after this process, then the candidate with the lowest number of votes is eliminated and their votes will be distributed to the other candidates based on the voter’s preferences.

If a candidate achieves a quota through this process, they will be elected. If the elected candidate has surplus votes, the voter’s next preference will be transferred.

If there are still Senate spots left unfilled after this process, the candidate with the second least number of votes will be eliminated and their votes distributed based on the voter’s preferences.

This continues until enough candidates receive the quota of votes required to be elected.

The proportional representation system allows a voice for minority parties in decision making in Australia.
