There are a number of realestate sites,
www.domain.com.au being one that springs to mind, and you could search on there.
It could even be not so much what you will pay somewhere but getting one somewhere at all, quite possibly further away from your desired area, for of late there have been media coverages of it being a tight market for renters and stories of hundreds of people doing rental property inspections and in some cases higher rental offers being made, a bit of a tendering situation in fact.
So do your searching, look and get in where you can quick.
