New South Wales: name and gender marker paperwork

Easy Read

• You can change your name with NSW Births, Deaths and Marriages. You can apply online.
• You can change the sex on your NSW birth certificate. You do not need surgery or any medical procedure.
• You need a form signed in front of a witness, and a statement of support from an adult who has known you for at least 12 months.
• After that, you can update your other documents, like Medicare and your licence.
• This is general information, not legal advice. Check the official page before you apply.

General information, not legal advice. Rules can change, so always follow the official page. Each fact below comes from the linked government source. Last checked 14 Nov 2026.

This page is for people whose birth is registered in New South Wales. If you were born in another Australian state or territory, use that state’s page instead. If you were born overseas, the rules for people living in NSW are noted where the official pages cover them.

1. Change your registered name

• You can apply online. It’s the quickest way.
• You need three valid identity documents, and one must be government-issued photo ID (for example a passport, driver licence or NSW Photo Card).
• You can change your name only once in a 12-month period and 3 times in your lifetime.
• If you were born in another Australian state or territory, apply to the registry where you were born.

2. Update your sex or gender marker

• From 1 July 2025, a medical procedure is no longer required to apply for a change of sex in NSW.
• Adults (18 or older) born or adopted in NSW need: proof of identity, a statutory declaration certified by an authorised witness, and a statement of support from another adult who has known you for at least 12 months.
• The official page does not list a doctor’s or psychologist’s letter as a requirement.
• Sex descriptors you can choose: female, male, non-binary or non-specified.
• Adults born overseas can apply for a recognised details certificate. You need proof of Australian citizenship or permanent residency and at least 12 months’ continuous residency in NSW.
• Changing both? NSW suggests applying for the change of name first, noting the Online Reference Number (ORN), then applying for the change of sex with that ORN so you only need to order one new certificate.

3. Update your other documents

There’s no official order for updating your other documents. This is one suggested order, not a rule. Check each agency’s page for what it needs.

1. Your registry: name and/or sex or gender marker

   Get your change of name certificate and/or new birth certificate (or recognised details certificate) first. Other agencies may ask to see them. See the two sections above.

2. Driver licence or photo card (NSW)

   Updated photo ID can make later steps easier. Service NSW: Change of name with Transport for NSW.

3. Medicare

   Name: call the Medicare program line and have a supporting document ready (for example a change of name certificate or reissued birth certificate). Gender: you can update it online in myGov (Medicare > My details > Edit), or by phone, in person or in writing, and Services Australia says you don’t need supporting documents. It notes this may affect cancer screening reminders. Services Australia: Medicare details.

4. Centrelink

   Legal name: bring your Births, Deaths and Marriages documents to a service centre. You can update your preferred name online in myGov if your Centrelink online account is linked. Centrelink may still use your legal name when it writes to you. Gender: update it in myGov (Centrelink > My details). Documents are only needed in some cases, such as Child Support records. Centrelink: update your name · Centrelink: update your gender.

5. Australian Taxation Office (ATO)

   Update your name in myGov (ATO > My profile). You’ll need to verify an identity document such as a change of name certificate or birth certificate. ATO: Update your name.

6. Passport

   If you change your name for reasons other than marriage or relationship status, the Passport Office says to stop using your current passport and apply for a new one. Passports show M, F or X. To change it, you provide one of the following:

   • a registry gender recognition certificate
   • a revised birth certificate
   • a recognised details certificate
   • a South Australian identity acknowledgement certificate
   • a statement from a registered doctor or psychologist on form B14.

   Not all countries recognise X. Check before you travel. Australian Passport Office: Change of name or gender.

7. Electoral roll (AEC)

   Update your enrolment details online. You’ll need a driver licence number, passport number, Medicare card details or citizenship number, or someone who is enrolled to confirm your identity. AEC: Update my details.

8. Banks, super, insurance and utilities

   There’s no single official process. Contact each provider directly and ask what they need. Usually it’s your new certificate and updated photo ID.

About this order: it’s a common, practical sequence, not an official rule. Federal agencies follow the Australian Government Guidelines on the Recognition of Sex and Gender, but each one has its own steps. Last checked 14 Nov 2026.
