As a fellow Victorian...
I had a long and painful experience trying to get the guy who assaulted me convicted (friend of a housemate at the time).

The cop running the case questioned his friends, giving him advance warning, and then went on leave for a month.

They eventually threw it out without holding him or anything as I'd been drinking (they were plying me, I was 16 at the time and asleep!), and had showed him 'sexually explicit material' (he saw some photos in my room of some friends and I in bathing suits on a recent uni camp). Oh, and I'd fought him off before he'd been able to rape me so there was no physical evidence.
