I guess you've already looked at
www.birdsaustralia.com.au and
www.sabirding.com?
There are a good number of Oz bird books, but best to get them there - google that subject and you should come up with at least 5! Doubtless many others will respond and tell you which is best.
Oz camp sites are properly organised and most have chalets if you're not renting a campervan The Australian Automobile Association has a camp site guide, as do several other organisations. It's usually worth while asking while in Adelaide on where you can get these brochures or the bird books. I'll be somewhere in Oz at that time, but I'm just going walkabout and with no particular schedule for several months!
