A Victorian chapter of the Lesbian Action Group (LAG) has launched a federal court challenge after the Australian Human Rights Commission refused to exempt the group from laws that prevent it excluding trans women from public events.
Why this matters
The case sits at the intersection of community autonomy and anti‑discrimination law. It will test how the Sex Discrimination Act and related protections for gender identity apply to voluntary organisations and to public, community-facing events. The court’s decision could shape how venues and groups across Victoria — and possibly nationally — set access rules for single‑sex or women‑only spaces.
What LAG says
LAG wants permission to run some women‑only events restricted to people it describes as “Lesbian Born Female”. The group argues those settings — particularly social and dating spaces for young or emerging lesbians — need places where participants born female can meet without the presence of trans women. Spokesperson Nicole Mowbray has said the organisation is not motivated by hatred and that it supports separate trans‑specific spaces as well.
LAG framed its request to the commission as narrowly targeted and temporary: an exemption for particular events, not a blanket ban on transgender participation in other contexts. Its lawyers told the court there is no general right to attend every community event and drew analogies with sex‑specific services that prioritise access by biological sex.
The Human Rights Commission response
The Australian Human Rights Commission declined LAG’s application. AHRC President Rosalind Croucher concluded that, since 2013, the law has prohibited discrimination on the basis of gender identity and that excluding transgender women from lesbian events is not consistent with those protections. The commission acknowledged the social value of lesbian gatherings but found the proposed exclusion inappropriate under current legal standards.
Venue and booking dispute
The Victorian Pride Centre, represented at the time by then‑CEO Justine Dalla Riva, told organisers it would not support the exemption. According to material filed in court, the Pride Centre says LAG did not disclose the later, broader exclusionary language when it initially booked the venue. The centre reviewed the booking and subsequently declined to endorse the request — a development now quoted in the court record.
Legal route and courtroom issues
After the AHRC refused the exemption, LAG sought administrative review and has appealed to the federal court, where Justice Mark Moshinsky is hearing the matter. Key questions for the judges include whether voluntary groups can lawfully limit attendance at public events on the basis of biological sex, how the Sex Discrimination Act’s protections for gender identity apply, and whether later changes to event descriptions affect the legal analysis.
Both sides have signalled they will present evidence on harms and rights. LAG has raised substantial funds to support the appeal; opponents argue the exclusion amounts to unlawful discrimination and risks deepening rifts within the LGBTIQ+ sector.
Community reaction
More than two dozen LGBTIQ+ organisations across Australia have jointly opposed efforts to deny recognition to trans women. Festivals, health services and community groups said the campaign to exclude trans women is harmful and does not reflect the priorities of most lesbian and queer communities. The signatories urged decisions that protect inclusion and avoid further marginalising people seeking services and safe spaces.
What’s at stake
A ruling for LAG could open the door to similar exemption requests by community organisers seeking narrowly defined single‑sex spaces. A ruling that upholds the AHRC would reinforce statutory protections for gender‑diverse people in public events, narrowing the circumstances in which organisers can lawfully exclude someone on the basis of gender identity.
