I live on the Gold Coast but need to travel to camping areas. The nearest are in the Border Ranges Nat Park (northern NSW) or Mt Mee (Archer camping area). Archer has a creek next to the camping area.
Areas within about a 3 hour drive are Crows Nest Nat Park, Cressbrook Dam, Mt Mee, Kenilworth State Forest, Cooloola Nat Park, Main Range Nat Park and Lamington Nat Park (just out of Canungra).
I usually go camping once a month, so if you are interested you are welcome to tag along on my next trip (end of Feb).
I hope this helps you.
