Voting in person is the most popular way to vote in New South Wales. It is usually quick and easy to vote in person at a voting centre or polling place, and election staff and officials are available if you need help.

When you arrive at the venue, there are usually lots of candidate workers standing outside the voting centre and polling place. These people work for the parties and candidates standing for election.

They will want to give you a 'how-to-vote card'. This is a paper that shows you how to vote for their party or candidate. You don't have to take these, but if you want to know how to vote for a particular party or candidate, they can be helpful.

When you get inside the venue, there may be a small queue of people waiting to vote. Elections staff will be inside the venue and will tell you where you need to go.

When you get to the issuing table an election official will ask you for your full name, date of birth and your address so they can correctly identify you on the electoral roll.

The election official will then ask you if you have voted before in this election. They have to ask this to make sure that people only vote once.

You don't need to show identification to cast an ordinary vote, but it's a good idea to take some with you, or to write your name and address on a piece of paper to show it to the election official. It will make it easier for them to find your name if it is difficult to pronounce or spell.

Voters elect members of the Legislative Assembly for four-year terms using an optional preferential voting system. You must write the number '1' in the square next to the candidate of your choice.

You can show more choices if you want, starting with the number '2'. It is up to you how many choices you show after your first preference.
