We have on the spur of the moment decided to leave on Boxing Day to go to Sydney and back. 8 days. We have a 20 ft van shower and toilet. Our dilemma is where to stay? On the way down we will look for free camp or rest stops off WikiCamps but once near Sydney I have no clue. I'm assuming like Brisbane all campsites over Christmas /new year are booked a year in advance and require at least 7 nights. Does anyone have any suggestions other than sit down for a few hours trying to call any and all campsites to get laughed at when I ask if there is any availability. We would like to get into a proper paying campsite for a few days to sightsee. Maybe someone knows of one that doesn't always get completely booked out or keeps a few sites for passing travellers? We love to spontaneously decide to go off somewhere but it doesn't work very well during school holidays. Any other suggestions would be welcome. We would really prefer not to because of security but do people ever park their vans in suburbs somewhere?
