Change of sex

For births registered in NSW

If you have had a sex affirmation procedure you can apply to have your new sex recorded on your birth certificate. The new birth certificate will not disclose that a change of sex has taken place.

If you have changed your name since your birth was first registered, an endorsement will appear on the new certificate stating your birth was 'Previously registered in another name'.

Your birth will be registered in the current year showing the new sex. Access to your original birth record is restricted by legislation, but can be accessed under certain circumstances. 

For births registered outside Australia

If you have had a sex affirmation procedure you can apply to register a change of sex.

Once a change of sex is registered a recognised details certificate can be issued. The recognised details certificate will record your new sex and current name. 

You can apply to record a change of sex if:

• you are aged 18 years or older or are the parent/s or guardian of a child, and
• you or your child has had a sex affirmation procedure.

In addition:

• you or your child was born in NSW, or
• if born outside Australia, you or your child is an Australian citizen or permanent resident and has lived in NSW for at least one year.
