A judge of the Federal Court of Australia is currently deliberating on Australia’s “what is a woman?” case: Tickle v Giggle. This is a pivotal moment for women’s rights in Australia as it will determine whether gender identity trumps biological sex under Australian sex discrimination law.

Today, the Tickle v Giggle case begins its four day hearing in the Federal Court, and it's not only the parties to the case who are on trial.

In a win for women and biological reality, the federal government has agreed to replace a government health form that calls mothers “birthing parents” after new mum and Giggle social media app founder Sall Grover decried the language as “exclusionary, alienating and derogatory” towards women.
