I also hear that they record your rego on the way in, and and if it isn't also recorded for a camp site slip they can tell, and pull you up at the gate on the way out and fine you.
It's supposed to be first come first serve with the camp sites (outside of school holidays) but people pay and "claim" them for their mates, it's a bit of a s fight especially if you arrive late on Friday night and then people wake you up in the morning and tell you to move as they've already paid for the empty site.
The WORST is that you can't pay the ranger in cash and have to pay between 1 and 3pm at the gate!
I'm thinking I will not be staying at Honeymoon bay during summer from now on.
