By now, we have established that Sydney is not cheap. With this come the horrendous rents. In general, a room can be calculated with 180-250 AUD per week. The prices vary from area to area. You might be able to safe some money by sharing a room (120 AUD). A lot of accommodations are available like that.
Nice areas to live in are Newtown and Glebe.
Both very close to Uni. Also Darlington, Camperdown and Anndale are just
around the corner. You will hear bad things about Redfern (there will
be a lot cheap rental offers available) and people will warn you not to
move there. However, in the end it is of course up to you.
There is
limited accomodation available via USyd. There are various colleges, which are basically
student
dorms with full board and accordingly expensive (300 AUD per week in shared rooms). There is also the Uni
village
which is right next to the Camperdown campus. They have shared appartments
there (approx. 5 ppl),
with not too high rents. However you have a fixed contract for 6 month
and
additionally you need to apply well in time. I was way too late for these options. So I decided to look for housing after arrival Down Under.
While I stayed in the hostel for the first days, I tried to figure out a place to live. It is most likely the easiest to search for something when you're there, rather than try to get something via the internet from overseas (You'll get scammed). As I said before, this is overall no problem at all, when you arrive in time (In general it is not too hard, since there is a lot of coming and going in Sydney all year round). The pages I checked for accommodation were mainly Gumtree , Flatmates and Domain. I also kept an eye on the university's blackboard, but I was a bit too late for that. It is important to call the people that offer rooms. Do not even start mailing. You can assume that they get tons of eMail and texts, so they will only make you an appointment to see the room when you call them. Also, don't be too hesitant. In the end, I got a place in Newtown. It was amazing. Newtown is a student area with heaps of bars, cheap places with good food and a lot of alternative stores. It is just a great atmosphere and you can easily mingle (or will get mingled with) and meet a lot of cool people (first and foremost locals). I was lucky and got a room on my own in a (more or less) freshly renovated house and shared it with 2 Italians, one Spanish and a Portuguese. It was a bit overpriced but okay for the location, and since I was a bit desperate after 1.5 weeks in a hostel, I just went for it. Another upside was the proximity to university. I could easily walk to classes or the lab within 15 min.
This is something you might want to think about. Public transport tickets are expensive - especially since there are no real student tickets. You get some discount on tickets when you are an exchange student, but if you need the busses and trains on a daily basis, it might add up.
A sidenote on the busses: If you take the bus, you need to KNOW where you want to get off. The stops are not announced. So try to figure out approximately where you want to go. Also, when you wait at a stop, you
need to wave at the busses for them to stop, otherwise they won't. The system works pretty well. Oh, and Australians are quite polite, so say your thanks when you depart from the bus! :-)
