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 Tasmania. 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 TAS are noted where the official pages cover them.

1. Change your registered name

• Adults (16 and older) can register a change of name online.
• You must not have registered a change of name in the past 12 months.
• Have proof of identity and evidence of any previous names ready.
• Changing your name is a separate process from registering your gender.

2. Update your sex or gender marker

• If you’re 16 or older and your birth is registered in Tasmania, you can apply to register your gender.
• The application includes a gender declaration. Service Tasmania says it must be witnessed by a Justice of the Peace or a Commissioner for Declarations (Service Tasmania: Apply to register your gender).
• Tasmanian law says the Registrar can’t ask for a medical certificate or other medical document about your sex, sex characteristics or gender (Births, Deaths and Marriages Registration Act 1999, section 28A). If you’re under 18, you may be asked for evidence of counselling about the application.
• You can choose whether your gender is shown on your birth certificate, and whether your gender history is shown.
• You can only register your gender once in a 12-month period.
• Change of name is a separate application (you can lodge both together).

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 (TAS)

   Updated photo ID can make later steps easier. Transport Tasmania: Changing your name and/or address.

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.
