Anyone have any experience with campsites around the Avon Valley NP? Is one site better or quiter than the others?

Looking to take my 3y/o camping (bush not beach) for a night or 2 once the fireban is lifted (15th??) and it appears that its the closest place to Perth? It's also got long drop toilets so i dont have to bring my own which is nice.

Are there any other places worth looking at within an hr or 2?
