Liberal and One Nation senators have used parliamentary hearings to grill human rights commissioners on their interpretation of discrimination law.
The landmark Giggle v Tickle appeal judgment, handed down earlier in May by the Federal Court, has resulted in a surge of campaigning by conservative parties.
The judgment found that a female-only app 'Giggle for Girls' was wrong to exclude transgender woman Roxanne Tickle under discrimination law.
The next day, Liberal leader Angus Taylor announced a policy to amend the Sex Discrimination Act to allow for cisgendered women to exclude trans women from gatherings.
"We will define biological sex in the act. Male or female. The sex you are born. And we will protect single-sex spaces across Australian life," he said.
