Same-sex marriage has been legal in Australia since 9 December 2017.

Under the Gender Reassignment Act (2000), in order to amend their gender markers, applicants must submit an application to the Gender Reassignment Board. Upon examination of the application, the Board verifies that the applicant has undergone gender affirming surgery (Article 15.b.i), that they have adopted "the lifestyle" and has "the gender characteristics of a person of the gender to which the person has been reassigned" (Article 15.b.ii), and that they have received "proper counselling" in relation to their gender identity (Article 15.b.iii).
However, in 2011, the High Court of Australia held in AB and AH v. Western Australia (2011) that the surgical procedure is no longer a requirement, but some sort of physical alteration must have taken place. In this instance, HRT can be seen to fulfill this requirement. If the Board is satisfied, they will issue a "recognition certificate" that enables the applicant to request a gender marker change on the birth certificate.
