cheap hostels in melbourne or surrounding suburbs?
I’m moving to melbourne to study and need somewhere to stay until I find a rental property. I’ve had a look at a few- the ones in the city centre and st kilda with cheap large dormitories are either already fully booked or booking out fast. So am wanting to look a little further afield perhaps.

Just have a look at http://www.hostelworld.com
They have heaps on there and you can book on line. You can search by availability as well so you’re not looking at ones that are full.
Where are you studying? It’s obviously also a good idea to look for some near where you study. The suburbs surrounding the city would probably be less busy.
