 Same-sex marriage advocates noted that same-sex marriage legislation should be inclusive of the rights transgender and intersex people, with intersex people being skeptical of the term "same-sex" marriage.These concerns were addressed by the federal legalisation of same-sex marriage in December 2017, which amended the definition of marriage to "2 people".As of 2017, only South Australia and the Australian Capital Territory did not require transgender people to divorce before registering an official change of gender on a birth certificate.
