Two small rainbow flag stickers were first put up on the Notre Dame Student Association (NDSA) office and boardroom windows at the Catholic university's Fremantle campus earlier this year.

“We took it upon ourselves to do stuff for our LGBTIQ students, because there was nothing," president Dylan Gojak told BuzzFeed News. "One of the first steps was putting up these ally stickers."



At the end of February, the stickers were ripped down. The NDSA put them back up. Last Wednesday, they were ripped down a second time.

Neither the NDSA nor the university knows who the culprit is.

But the vandalism has placed the stickers in the spotlight – and prompted complaints to university management arguing the "divisive" rainbow flag has no place on campus.
