Last time I was there it was 20 bucks per head. We were chatting about it in front of some others whom had driven in and were camping. They had also been hit with a $20 fee to camp, make use of the portaloo's etc, this was on top of the caravan parks 'normal' fee.
i felt a lot happier paying my 20 bucks thats for sure!
And seriously...when you consider this as a percentage of the cost of your flight...............................
I reckon the fuel charges were much worse.
