Can you update your gender on formal documents?
On most formal documents, yes. However, different documents have different requirements and different gender identity options.
Unfortunately, some trans and gender-diverse people may have limited ability to update their gender on some formal documents in SA.
What steps are involved with making an update?
The steps required depend on whether the document you would like to change is issued by:
- a state or territory government organisation; or
- a federal government organisation
How to update the gender on your South Australian birth certificate
Birth certificates are issued and regulated at a state and territory level. This means that the approach to update your birth certificate to match your gender identity will depend on which state or territory issued your certificate. If your birth certificate was issued in SA, this is managed by the SA Registry of Births, Deaths and Marriages.
In SA, you can apply to ‘record a change of sex or gender identity’ once per 12-month period and up to three times in your lifetime, if:
- you were born in SA; or
- your birth was registered in SA; or
- you were born overseas and you have been living in SA for at least 12 months.
In SA, you must have had clinical treatment from an Australian medical practitioner or psychologist before you can update the sex marker on your birth certificate. Gender-affirming surgery is not required.
What if your birth was registered outside South Australia?
If your birth was registered somewhere else in Australia, you will need to apply to update your gender in the state or territory you were born in. The factsheet for the state or territory that issued your birth certificate will have the eligibility requirements for updating the gender on your birth certificate.
Identity acknowledgement certificate
People aged 18 or older who were born overseas and have lived in SA for at least 12 months can apply for an identity acknowledgement certificate. To apply for an identity acknowledgement certificate, you must have had clinical treatment from an Australian medical practitioner or psychologist in relation to your sex or gender identity.
The identity acknowledgement certificate can help you update your gender on other documents.
How do you apply to update the sex marker on your birth certificate or to apply for an identity acknowledgement certificate?
- Complete the relevant form:
- If you are aged 18 or older, use the ‘Application to record a change of sex or gender identity – adult‘ form. If you would also like to change your name at the same time, you will need to complete Section C of the form, which must be signed in front of a Justice of the Peace, Notary Public, Police Officer or Practising Lawyer.
- If you are under 18, you or your parent or guardian can use the ‘Application to record a change of sex or gender identity for a child‘ form.
- If you would like to change your name at the same time, you will need to email ocba-bdmregistrations@agd.sa.gov.au for further information.
- Get your identity documents. You must provide one document from each of the four categories listed on pages 3 and 4 of the form. All documents (except your original birth certificate) must be certified (see the ‘Identification’ section of the form).
- If your parent or guardian is making the application on your behalf, in addition to providing your identity documents, they must also both provide proof of their identity, by providing one document from each of the four categories listed on page 4 of the form.
- Get your supporting statement. You must provide a statement by a medical practitioner or psychologist certifying that you have received appropriate clinical treatment in relation to your sex or gender identity (see Section B of the form for more information).
- Submit your application and supporting documents by posting them to:
Births, Deaths and Marriages Consumer and Business Services
GPO Box 1351
Adelaide SA 5001
If you have any questions or would like to speak to someone, you can email ocba-bdmregistrations@agd.sa.gov.au and make an appointment. - Pay the application fee.
Fees can change. Current application fees are published at https://www.sa.gov.au/topics/family-and-community/births-deaths-and-marriages/change-of-sex-or-gender-identity.
If you are under 18
If you are under 18, your parent or guardian can apply on your behalf. However, the South Australian Civil & Administrative Tribunal (SACAT) must also approve your application.
You or your parent or guardian can use the ‘Application to record a change of sex or gender identity for a child‘ form. First your parent or guardian must apply to the SA Registry of Births, Deaths and Marriages (this process is explained above).
Once this application has been assessed by the SA Registry of Births, Deaths and Marriages, your parent or guardian will need to make a separate application to SACAT.
How to apply to SACAT
- Complete the online application form. Under Step 2, select the ‘Births, Deaths and Marriages Registration Act’ option and the ‘Original Application (Births, Deaths and Marriages Registration Act)’. Under Step 3, select ‘Application to register the change of a child’s sex or gender identity’ option.
- Get your supporting documents. You must provide:
- a copy of the Births, Deaths and Marriages change of sex or gender identity application form;
- a certified copy of your parent or guardian’s proof of identity;
- a certified copy of your (the child’s) birth certificate;
- a supporting statement from a medical practitioner or psychologist certifying that you (the child) have received appropriate clinical treatment in relation to their sex or gender identity and have the mental capacity to consent to the application;
- a letter from the other parent acknowledging the application and whether they are supportive;
- a copy of any previous decisions made by a court or SACAT regarding a change of sex or gender identity; and
- any other documents you think are relevant to the application.
- Pay the application fee.
- Attend the hearing (if required). Generally, SCAT requires a hearing and during the hearing you may be required to provide further documents during a hearing. You (the child) will also be interviewed during the hearing, as well as any other relevant people (eg family members).
- Contact the Registrar of Births, Deaths and Marriages to progress your application. Once SCAT has made a final order, you must contact the Registrar’s office to ensure that your application is progressed.
How to update the gender on your driver’s licence records
The steps to update the records associated with your driver’s licence depend on the state or territory that issued your licence.
What you need to do in SA
There is no sex/gender marker on physical driver’s licence cards issued in SA. However, Services SA records the gender of each person when they apply for a licence.
To update the records associated with your driver’s licence, you will need to visit a Service SA service centre with one of the following documents:
- a statement from a registered medical practitioner or a registered psychologist;
- a valid Australian Government travel document, such as a current passport, which specifies your gender;
- an amended Australian state or territory birth certificate, which specifies your gender; or
- an Australian state or territory gender recognition certificate or recognised details certificate (called an ‘identity acknowledgement certificate’ in SA), showing that a Registrar of Births, Deaths and Marriages has recognised the gender you want to update your record to.
You can update your records without having officially changed your name or updated your gender, as long as you have one of the above supporting documents.
You can choose from the following gender options:
- ‘M’ – male
- ‘F’ – female
- ‘X’ – this option is available if you do not identify as either male or female.
How to change your gender on federal government documents, such as your passport, and Medicare or Centrelink records
You can change your gender on federal documents or records by applying to the agency that looks after the document or record that you want to change.
There are Australian Government Guidelines on recognising gender (see the link further below under ‘Where to Get Help and Information’). This means that:
- Federal departments and agencies must take all reasonable steps to correct the gender information in their records to make sure it is accurate, up-to-date, and not misleading.
- You can apply to federal agencies, such as the Department of Foreign Affairs and Trade and the Services Australia, directly to change your gender on your personal record, or as shown on your passport.
Do you need to provide supporting documentation?
Under the Australian Government Guidelines, you need to provide one of the following with your request for a change of your recorded gender:
- A statement from a registered medical practitioner or registered psychologist which specifies your gender.
- A state or territory gender recognition certificate or recognised details certificate showing a change in sex.
- A valid Australian government travel document, such as a valid passport, which specifies your gender.
- A state or territory birth certificate which specifies your gender, or a document from an Australian Registrar of Births, Deaths and Marriages recognising a change of gender.
You do not need to have had surgery and/or hormone therapy for the recognition of a change of gender in federal government records. This means that even though you may not have any related medical procedures, you can still apply to correct the gender information recorded on your personal record. See the Australian Government Guidelines.
| Document | Department | What you need to do |
|---|---|---|
| Your Medicare card | Services Australia | If your Medicare online account is linked to myGov, you can update your gender online by signing into myGov or the myGov app. If you don’t have a myGov account or Medicare online account, you can call the Medicare program line, visit a service centre or send a letter via post. You won’t need to provide any supporting documents when you make a request this way. The Medicare contact details are available here. If you update your gender on your Medicare card, this may change the reminders you receive for cancer screening under Medicare. |
| Your Centrelink file | Services Australia | If your Medicare online account is linked to myGov, you can update your gender online by signing into myGov or the myGov app. If you don’t have a myGov account or Medicare online account, you can call the Medicare program line, visit a service centre or send a letter via post. You won’t need to provide any supporting documents when you make a request this way. The Medicare contact details are available here. If you update your gender on your Medicare card, this may change the reminders you receive for cancer screening under Medicare. If your Centrelink online account is linked to myGov, you can update your gender online by singing into myGov, or the myGov app. If you don’t have a myGov account, or a Centrelink online account, you’ll need to create these accounts or call Centrelink. You will only be required to provide supporting documents to update your gender if you are either: – updating your gender in your Child Support personal record; or – verifying your identity under an international agreement with Centrelink. If you are required to provide supporting documents, you can provide one of the documents outlined in the Australian Government Guidelines. |
| Your passport | Department of Foreign Affairs and Trade | For both a new passport and/or to change your gender on an existing passport, you need to start the application process online and then print it for lodgement. For this application, you must also provide one of the documents outlined in the Australian Government Guidelines. If you are providing a statement from a registered medical practitioner or registered psychologist, they must complete DFAT’s Form B-14. If you are in the process of transitioning, you can provide a statement from a registered medical practitioner or psychologist that you have had or are receiving appropriate clinical treatment for gender transition. This should be provided on DFAT’s ‘Declaration: sex/gender of passport applicant form’ (Form B14). |
What happens when there is inconsistent gender information in my supporting documents?
If you identify as intersex, or are in the process of affirming your gender, your supporting documents may not be the same and may refer to different genders or gender markers. If this is the case, departments may ask you for more information and supporting documents to confirm your gender identity.
Under the Australian Government Guidelines, departments will prioritise either your passport or the supporting document that is the most recent. The Australian Government recognises that there may be legitimate reasons for holding conflicting documents, for example people who identify as non-binary or intersex may want to hold a passport with a particular binary gender marker to ensure their safety while travelling overseas.
Will every application and outcome be the same?
No. The different departments may have different application forms and therefore varied outcomes around changing your gender identification.
What’s an example?
Services Australia can update your gender as male, female or non-binary for their personal records system. You can also tell them you prefer not to use a courtesy title such as Miss, Mr or Ms.
Whereas…
The Department of Foreign Affairs and Trade can record your gender as M (male), F (female), or X (indeterminate/intersex/unspecified) on your passport. However, the Department notes that those travelling with a passport showing ‘X’ may encounter difficulties when crossing borders due to its infrequent use. In more conservative countries or areas you may become the focus of unwanted attention.
