Renting a caravan and setting up in someone's back yard does seem like one option people have tried, but there are times it runs foul of local ordinates in place regarding length of time etc.

Some people would see it purely as a housing crisis but I feel it really ignores the fact that a great number of van parks have either priced themselves out of being an affordable alternative or faced increased costs and further regulations which inevitably saw them close shop. Presently since solar means less reliance on powered sites, I see more vans and motor homes pulled up near rest areas, and other like places for a few days until they move on.

In my locale, North Central Queensland, even 30 years ago the caravan parks were starting to stall, many were simply encroached and then displaced by urban sprawl, but there was also the dwindling seasonal migration of workers from south to north and back south again following the seasonal jobs. I think it was just banks and finance firms made it too tough on those who did not have permanent jobs to borrow to be able to put down roots on a block of land - the only real choice was to aim for permanent work instead. So though I don't recall all the parks that used to exist around my parts I still recall the few large parks that made way for a small suburb of residential houses ...

Australia needs to stop playing with the world economy bringing in crazy numbers of people and fix their local problems first. THe speed is whats causing too many factors to change and too many ordinary people to lose.
