We stayed here a couple of years ago as our first ever camping trip with our kids, as it is very close to home. It was very busy and the campsites weren't very big but the amenities were great. There is a playground for the younger kids and a basketball hoop and tennis courts. My kids went spotlighting at night and found lots of creatures.
The kids loved floating down the river with the tide until it hit the beach. Just be careful of diving in near the rocks as one of my daughters split her hand open on an oyster shell on the first morning we were there!! Woy Woy hospital take kids on an emergency basis and they had her stitched up and with a plastic bag over her hand continued on floating in the water.
And yes the fish and chip shop shuts around 6pm so get in early!!
