The short answer

check and update your electoral enrolment

You check your electoral enrolment through the Australian Electoral Commission's online enrolment portal and update it whenever your name, residential address or eligibility details change. Enrolment is compulsory for Australian citizens aged 18 and over, and you must update your details within a set period after moving. The AEC cross-references enrolment data with other government records, but the onus is on you to ensure your details are current. If you are not correctly enrolled, you cannot vote in a federal election, by-election or referendum, and you may receive a penalty notice for failing to enrol or update.

This guide explains the federal position first. State, territory and local elections can use different rules, dates and ballot systems, so the commission named on your election material is the final operational source.

The useful question is not only “what is the rule?” but also “who administers it, which document controls it, and when might it change?” That distinction prevents an accurate general explanation from becoming wrong advice in a particular election, chamber or policy setting.

Who must enrol and when you must do it

Enrolment is compulsory for all Australian citizens aged 18 years and over. You can provisionally enrol from the age of 16 so that your enrolment becomes active on your 18th birthday. If you are 17 and an Australian citizen, you may also apply for provisional enrolment. The Commonwealth Electoral Act 1918 requires you to enrol within 21 days of becoming eligible. This includes citizens who have turned 18, people who have become Australian citizens, and eligible voters who have not previously been enrolled.

If you move to a new address, you must update your enrolment within a set period. The AEC uses your enrolled address to determine which electoral division you belong to for federal elections. Living at an address for more than one month generally triggers the obligation to update, even if the move is within the same suburb. Students, people who travel for work, and those with multiple residences should enrol at the address they consider their principal place of residence.

How to check whether you are correctly enrolled

The AEC provides online tools to check your enrolment. You can visit the AEC enrolment portal and enter your personal details to confirm your enrolment status, enrolled address and the federal electoral division you are in. Do not rely on an old polling card, a third-party website or a social media post to tell you whether you are enrolled. The AEC is the sole authoritative source for federal enrolment data.

If you have recently moved, changed your name through marriage or a legal process, or become an Australian citizen, you should check your enrolment promptly. The AEC may also send you correspondence if it detects a potential discrepancy, but waiting for a letter is not a substitute for checking yourself. Enrolment data is used to send polling information and to determine which candidates and ballot papers apply to your division, so an outdated enrolment can mean you receive the wrong ballot.

How to enrol or update your details

You can enrol, update your address or change your name through the AEC website. The online form requires identification such as a driver licence, passport, or Medicare card — or you can have someone who is already enrolled confirm your identity. If you cannot complete the online form, paper enrolment forms are available at AEC offices, Australia Post outlets, and Centrelink, or you can request one by phone.

The AEC processes most online enrolments within a few days. You will receive confirmation once your enrolment is updated. During a federal election period the enrolment roll closes approximately seven days after the writs are issued, and no new enrolments or address changes can be processed after the close of rolls. This means you must check and update your enrolment well before an election is announced if you want to avoid being locked out.

What happens if you are not enrolled or your details are wrong

If you are not enrolled and do not vote at a federal election, you may receive a penalty notice. The AEC sends apparent failure-to-vote notices after each election, and you may be asked to provide a valid reason for not voting. Not being enrolled is not itself a valid reason — enrolment is a separate legal obligation. If your details are out of date and you vote in the wrong division, your vote may still count for the House of Representatives if the ballot paper is the same, but you may also be investigated.

For Senate elections, voting in the wrong state or territory can invalidate your vote because Senate ballot papers are state-based. It is therefore safer to update your enrolment whenever your circumstances change rather than waiting until an election is called.

Enrolment for special groups: overseas voters, itinerants and people with no fixed address

Australian citizens living overseas can enrol as overseas electors if they intend to return to Australia within six years. If you are going overseas temporarily, you do not need to change your enrolment — you remain enrolled at your Australian address and can vote by post or at an overseas voting centre. People with no fixed address, including those experiencing homelessness, can enrol using a place of origin or an address where they are known. The AEC has specific forms and guidance for each of these categories.

Members of the Australian Defence Force and Australian Federal Police serving overseas have separate enrolment arrangements. Itinerant workers and people who move frequently should choose the address that best represents their connection to a community. The key principle is that the AEC needs a reasonable basis for assigning you to a federal electoral division.

How enrolment data is used and protected

The electoral roll is used to compile the certified list of voters for each polling place, to draw electoral boundaries, and to conduct elections. The AEC shares some enrolment data with state and territory electoral commissions for joint roll arrangements, but it does not sell the roll for commercial marketing. Certain entities such as political parties, members of parliament and approved medical researchers may receive extracts of the roll under strict legislative controls.

Your personal information is protected under the Privacy Act 1988 and the Commonwealth Electoral Act. You can apply for silent enrolment if having your address on the public roll would put your safety at risk. Silent electors are still enrolled and can vote, but their address does not appear on the publicly available roll.

Common questions

Before you rely on the answer

Can I check my enrolment without a driver licence or passport?

Yes. If you do not have a driver licence, passport or Medicare card, you can still check your enrolment by contacting the AEC directly by phone or visiting an AEC office. You may need to provide alternative identity verification such as a citizenship certificate or have someone already enrolled vouch for your identity.

What if I moved house just before an election was called?

If you moved after the close of rolls, you cannot update your enrolment for that election. You must vote at a polling place in the division where you are still enrolled, or apply for a postal vote sent to your old address, or cast an absent vote. Contact the AEC for specific guidance based on your circumstances.

How often should I check my enrolment?

The AEC recommends checking your enrolment whenever you change address, name, or citizenship status, and at least once before each federal election. Even if nothing has changed, checking takes a few minutes and confirms your details are correct before the close of rolls.

Does state enrolment automatically update my federal enrolment?

In most states and territories, yes — there is a joint roll arrangement between the AEC and state or territory electoral commissions. When you update your enrolment with one, it should flow through to the other. However, you should still verify your federal enrolment directly with the AEC after any change, particularly close to an election.
