Try Camping in Southern & Central Qld by Martin Bowerman (Guy from Creek to Coast) has quite a few photos, but good description.
Camps 3/4 has good listing and you can buy a companion book with site photos. Not alot of detail on each site though. More for travelling around australia.
If you focus is towards Caravan parks try the Q-Park guide. Most camp stores and caravan aprks usually have a copy.
Usually if you find a ground, just do a google and you will find a webpage somewhere with at times good info.
Never argue with a fool! They drag you down to their level, and beat you with experience!
