16 Sept 2026 – One hundred women’s organisations, LGBTIQ+ groups, unions, disability groups and mental health advocates have united to oppose proposals to redefine ‘sex’ under Australia’s anti-discrimination laws, warning that doing so would put longstanding protections for trans and intersex people, as well as women, at risk.
The letter comes a day after a Coalition Bill seeking to rewrite the Sex Discrimination Act (SDA) was voted down in the Senate for the second time.
Similar attempts to amend the Act have also been made by a Nationals MP and One Nation.
The open letter was signed by organisations including the Australian Council of Social Services (ACOSS), Australian Multicultural Women's Alliance (AMWA), Victorian Trades Hall Council, Australian Services Union, Fair Agenda, ACON, National Foundation for Australian Women, Women With Disabilities Australia, Equality Australia, Women's Electoral Lobby and Women's Legal Services Australia.
Sent to all federal MPs, the letter urges them to reject any changes that would redefine “sex” in the SDA or remove gender identity as a protected attribute, warning that such changes would undermine essenital protections against discrimination.
