I work for the West Australian Dept. of Environment and Conservation. I help manage the Lane Poole Reserve which has a large area set aside for camping along the banks of the Murray River. Its right in the forest and is a truly beautiful spot. There are five campgrounds that you need to book ahead for. Charlies Flat, Tony's Bend, Yarragil, Chuditch and Stringers. Three campgrounds where you can just turn up and pick your spot, Baden Powell, Nanga Mill and Nanga Townsite. Here is the link to the booking website and a bit more information http://www.dec.wa.gov.au/campgrounds/ ITs a great spot and we usually have local kombi groups camp there a few times a year. Check it out if you're down this way.
