Haven't been here myself but it's been recommended to me by 3 separate people. 30/40mins from SeaWorld and Dreamworld. The weekend we wanted to go they had a scout camp on and we ended up in a caravan park.
And I believe they allow fires.

I drove in one day to have a look, I guess it depends on what you are looking for but decided it wasn't for me. Nothing in particular wrong with it, it's good reviews is what got me to have a look in the first place.
I think if I am camping to get away from everything I want to feel like I am away from everything and I want either want to be by water or have great views and for me, It kind of had the feeling of just camping in the paddock in front of someone's house without either great views or water. Plenty of other people seem happy with it however, I guess it depends on what you are after and what you are comparing it too.
this is a nice spot away from everything, but getting on the limit of how far away you'd want to be. The unpowered area is nicer then where their powered area is IMO (I think the powered area is up near the house from memory, but happy to hear otherwise).
Also did a drive by here one day and it looked nice, was a bit packed in for my liking but it was a long weekend. Although I have been digging the solitude of some youcamp sites as we are set up for them, this one is up there for a trip with friends who aren't. I assume the normal camping is on the side of the creek where their house is and the "bush camping" is on the other side just with the portaloo's?
