Sall Grover
Filmmaker, Giggle founder and sex-based rights campaigner
Australian filmmaker and app founder Sall Grover spent five years at the centre of one of the most consequential legal battles over sex-based rights in the common-law world. The Tickle v Giggle case is not just an Australian story — Ireland's own self-identification gender law leaves single-sex spaces facing strikingly similar legal exposure.
Sall Grover is an Australian filmmaker and screenwriter who founded Giggle for Girls, a social-networking app built exclusively for women. The platform used facial-recognition technology to verify that users were female — a design decision rooted in the conviction that women are entitled to single-sex digital spaces and that biological sex is a meaningful and legally defensible category.
In 2021, Roxanne Tickle, a transgender woman who had been removed from the app, filed a federal sex-discrimination complaint. The case that followed — Tickle v Giggle — became one of the most closely watched legal confrontations over sex-based rights in the Anglophone world. Grover contested it for five years, arguing that a provider of a genuinely single-sex service has the right to rely on biological sex in determining membership. The Federal Court of Australia ruled against her in 2023, a decision that reverberated through women's organisations in Australia, the United Kingdom and beyond.
In the Beyond Gender episode Sall Grover vs the Gender Lobby: The Women's App That Sparked a Legal War (#40, September 2025), she joined hosts Stella O'Malley, Mia Hughes and Dr Bret Alderman to trace the full arc of the case — the original vision, the litigation process, its personal cost, and what the outcome means for single-sex services across common-law jurisdictions. The episode draws direct parallels with Ireland: the Gender Recognition Act 2015 permits legal sex change by statutory declaration, without medical gatekeeping, and Irish equality law's single-sex exemptions remain untested in comparable litigation.
For Irish listeners working in healthcare, education, sport or policy, Grover's experience amounts to a live precedent. The central question her case put before the courts — who has the legal authority to define a women-only space — is one that Irish law has not yet been asked to answer definitively. Waiting for a test case to arrive is itself a choice.
