Jayne and I have considered freecamping and may still do that given it's a money saver, but what we have seen across SA and WA has turned us off somewhat.
Every single site we have seen and stopped at in SA or WA to make lunch and have a cuppa has been completely trashed with rubbish spread across the sites as if its a rubbish tip. One that sticks in my mind was on the Nullarbor. We pulled in to consider staying there. The views were magnificent but rubbish was strewn from ahole to breakfastime. Jayne and I looked at each other and agreed it was not only disgusting it was distressing. The Nullarbor is a pristine environment BUT some people are treating these sites like a rubbish dump. Rubbish bins are provided but they are either overfull or not used at all.
Jayne felt that it may be backpackers that have no connection to OZ who just don't take care and who refuse to pay for a park. I'm not so sure, given the extent of the problem. Mind you, we have come across a few backpackers in their shithole vans and they were somewhat UNCLEAN and off their chops! But that is being unfair and I'm sure there are clean, caring backpackers........I'll let you know when we see one!
No wonder a number of councils refuse to allow freecamping....someone is giving it a bad name.
