Don't go on campus, people were trying to get out of there, it's a dump, there are no carpets and it's like a barracks. There are better and cheaper options available. Look up flatmates.com.au or there are off campus places. If you go with off campus places you'll be locked into a contract too that extends beyond the time you'll be there assuming you go home for holidays.
Southport is the best area to live in for shopping, parkwood is closer to the campus. Most dent students live near the hospital from second year on as the first year is mainly at the parkwood campus and after that moves to the gh1 hospital campus.
You can live at either and bus between , there are some subjects at gh1 like doh every wed at 8am and anatomy labs.
