yeah, there is a meetup forum, we'll get something organised once you're here! I'm actually in europe for most of july, I get back on the 26th. I started renting my place this year, and I did all of my househunting through
www.realestate.com.au - but my boyfriend and I were looking for an apartment, if you want a room in a house that is already being rented, I would recommend your university's housing service. I don't know what uni you are at, but at UTS the housing service hooks up people who need rooms with people who have rooms - so it might be worth finding out who to email there.
