Hi Tony
Found another good Caravan Park for you. Sorry it took me a few days to respond.
Check out: Brownhill Creek Caravan Park

Very handy place to everything and cars would be very secure here - no passing traffic to spot them. Very good carwash (they do mine every week) 5 minutes away from this spot.
Look forward to seeing you soon.
Regards
Gaela
