There is actually a long drop dunny at the camp grounds near the boat ramp, but like nipsta said no showers and the only water available is from a water tank so is subject to how much rain/visitors have been there. Think they have a bit of a pub set up at the general store (you can get take aways there anyway).
Nipsta you could try letting the people at the fishing store know the where abouts of your pots. Pretty sure they could organise a local to retrieve them.
