Hannah Williams invited her girlfriend, Savannah Supski, to come with her to a dance held by Ivanhoe Girl's Grammar. The organizers said that she could not come to the event unless accompanied by a boy.
Hannah Williams told the Sydney Morning Herald she was "very upset".
"I put a lot of effort into trying to fix things. I had meetings with principals; I had meetings with principals; looked through the Equal Opportunity Act; all my friends put posters up around the school and the teachers ripped them down. There was an easy solution; they just needed to let me go with my girlfriend," she added.
Heather Schnagl, the director of the school, explained her decision by saying that she prefers to encourage girls to socialize with boys.
What a bad excuse! It's just a way of saying no to same-sex couples.
Heather Schnagl also explained her decision by saying that Savannah was younger. Hannah is 16 and is in Year 11 while Savannah is 15 and is in Year 10. The ball is organized for students in Year 11 only.
But Hannah said her friends attended the event with younger boys and that this posed no problem.
Hannah's father filed a complaint with the Equal Opportunities Commission before to choose to remove it as Hannah became too stressed about it.
The girls decided to go to another school where same-sex couples can attend events.
