Because they don't want to fund the LGBT student group and Arthur wants to support his mate Merlin and Merlin's bloody annoying boyfriend? Merlin was a charity kid at Timbertops, right? That where they met because, like, Arthur didn't go to Geelong Grammar.

Actually, I don't know how student union funding works these days. Fees were compulsory when I was at Uni so we had, you know, ALL the resources.
