No more males in female divisions for World Athletics

The World Athletics Council has approved new regulations to prevent males participating in female divisions. All athletes participating in female divisions at the World level will be required to undergo a once-in-a-lifetime test for the SRY gene – a reliable proxy for determining biological sex. 

How you can help

Resources

Equip yourself, family, and friends with these helpful resources on the trans issue.

Donate to Change the Law

Right now, Australian law does not clearly recognise biological sex.

That gap has real consequences. It creates confusion in policy, weakens protections for women and girls, and leaves ordinary Australians exposed for stating basic biological facts.

Binary’s Change the Law campaign exists to fix this.

Your donation funds the national advertising needed to put this campaign in front of decision makers and politicians.

This is how public support becomes political action.

Donate now to help take this petition nationwide – and make it impossible to ignore.

Campaigns

Our organisation aims to promote and celebrate the inherent differences between boys and girls, men and women. We uphold the biological assertion that there are two complementary sexes.

Volunteer

Volunteer with Binary and help voters fight against the trans agenda and celebrate the true diversity of men and women, to defend vulnerable children, protect women in sport, and promote the biological truth that gender is binary: male and female.
