Northern Territory: name and gender marker paperwork

Easy Read

• If you are over 18, you can change your name in the NT. You must give a detailed reason.
• To change your sex or gender, you must have been born in the NT. You need a statement from a doctor or psychologist, or to be intersex.
• After that, you can update your other documents.
• 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 Northern Territory. 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 NT are noted where the official pages cover them.

1. Change your registered name

• You must be over 18, and either born in the NT or born overseas and living in the NT for at least 12 consecutive months. If you were born interstate, apply in that state or territory.
• You sign the application in front of a witness over 18.
• You must give a detailed reason. The NT page says statements like ‘I want to’ or ‘personal’ aren’t detailed enough.
• After you apply, you may be asked for a national police check at your own cost.

2. Update your sex or gender marker

• Adults must be born in the NT and over 18.
• Evidence is required. You must be an intersex person or have received appropriate clinical treatment related to your sex or gender. The NT page gives surgery, hormone therapy and counselling as examples.
• The evidence is a statement from a medical practitioner or psychologist registered in Australia, or a recognition certificate issued under any law.
• You can register as male, female, non-binary or unspecified.
• You return your existing birth certificate with the application.

Born outside the NT? The NT page says adults applying to change their sex or gender must have been born in the NT. It doesn’t list an option for people born overseas who live in the NT. Contact NT Births, Deaths and Marriages, or a legal service, if this applies to you. Last checked 14 Nov 2026.

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 (NT)

   Updated photo ID can make later steps easier. NT.GOV.AU: Change personal details on your driver licence.

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.
