Gangbangs/group sex Melbourne

Are there any regular/semi regular gangbang/group sex parties in Melbourne? 15 years ago when I lived in Brisbane I was invited to a regular gangbang party. I used to be a member of an exclusive 'mens group' that had quarterly stripper lunches. It was common for guys to bring their secretaries, girlfriends and wives along. Anyway, at one of these lunches a couple of guys had brought their wives along and I received a call a few days later from the organiser saying would I like to come along to a gangbang for one of the wives. I'd never been to one, but was extremely curious. They booked a nice hotel suit over at south Brisbane and we (all the guys ... about 15 of us) chipped in $50 to pay for the room, beers, pizza, etc. I had the time of my life. Totally awesome and opened up my mind to a whole new world of kinkiness. Anyway, I was wondering if there are any parties in Melbourne or groups looking for a new guy as I am new in town??
