The legal framework

Same-sex marriage was legislated in December 2017 following a voluntary national postal survey. Federal discrimination law has covered sexual orientation, gender identity and intersex status since 2013, though exemptions for religious bodies remain contested. Bans on conversion practices have been enacted by several states and territories rather than federally, with penalties that in some jurisdictions include imprisonment.

Australia legislated marriage equality in December 2017 following a voluntary postal survey in which a clear majority voted yes — a process widely criticised as unnecessary and harmful but which produced a decisive result. Conversion practices are banned state by state rather than federally, with Victoria, Queensland, the ACT and New South Wales among those legislating. Federal discrimination law covers sexual orientation, gender identity and intersex status.

In practice

Cost and coverage

Human rights complaints are free; community legal centres advise at no cost.

Recent changes

More states have legislated against conversion practices, and a review of religious exemptions in federal discrimination law has been under consideration for several years without resolution.

Where to go

Worth knowing

Religious exemptions are the live issue. In some states a faith-based school or employer retains latitude that would be unlawful elsewhere, so the answer depends on where you are.

Frequently asked questions

Are conversion practices banned in Australia?

In several states and territories, not federally. Victoria, Queensland, the Australian Capital Territory and New South Wales have legislated, with differing scope — some criminal, some civil and complaints-based. Check the law of your state; the differences are substantial.

What does federal discrimination law cover?

The Sex Discrimination Act prohibits discrimination on grounds of sexual orientation, gender identity and intersex status in employment, education, goods and services and accommodation. Religious bodies retain exemptions in some contexts, an issue that has been reviewed repeatedly.
