Gay marriage was legalized in Australia on December 9, 2017.

This followed the passage of the Marriage Amendment (Definition and Religious Freedoms) Act 2017 by Parliament on December 7, with royal assent on December 8. The law took effect the next day, recognizing overseas same-sex marriages immediately and allowing the first Australian ceremonies shortly after, including one on December 15, 2017.

Key Timeline

  • 2004 : Federal law explicitly banned same-sex marriage under the Howard government.
  • 2013 : Australian Capital Territory passed a local law, but the High Court struck it down for conflicting with federal rules.
  • 2017 Postal Survey : Over 61.6% of respondents supported legalization in a voluntary national poll.
  • December 9, 2017 : Nationwide legalization began; first weddings followed in mid-December after exemptions to the waiting period.

Road to Change

The push gained momentum after years of state-level efforts and decriminalization of homosexuality across states (e.g., South Australia in 1975, Tasmania last in 1997). A national conscience vote ended the ban, making Australia the 23rd country worldwide and second in Oceania after New Zealand. Public support was strong, with the survey reflecting broad backing despite earlier divisions.

First Celebrations

Couples like Jill Kindt and Jo Grant held Australia's inaugural legal same-sex wedding on the Sunshine Coast just days later. More followed on December 16, with full ceremonies ramping up in January 2018 post-waiting period.

TL;DR : Legalized federally on December 9, 2017, after parliamentary vote and survey approval—marking a pivotal win for equality Down Under.**
