The one on the beach clamped down on vans coming in and just topping up water and dumping waste at the displayed fee last year. He insisted you had to stay at least one night which was a slightly higher fee, which including waste dump as often as you wished. No facilities at all other than the water and dump. Water was paid for if you stayed or not, at 10 cents per 10 litres. We used at a few times over the years.
