Hey! Welcome to UQ dent, you're going to have a blast! There aren't any colleges near herston and the student accomodation is either expensive or you're sharing with like 5-6 other people, however if you don't mind that, check out Iglu student accom. On the other hand, me and a friend (both going into 3rd year dent) have a spare room to rent in a modern townhouse close to the dental school. Let me know if you're interested.
