In rural NSW there are a shitload of cheap houses for sale in dying towns. It's probably the same in rural WA.
The reason why some communities have made housing so cheap - both to buy and rent - is because they need a certain population to keep infrastructure such as schools, hospitals and doctors.
If you're wanting to simply own your own home rather than looking to increase your net worth or make a profit, it's something you might want to look into.
If land (in the outback) is relatively cheap and housing (near the city) relatively expensive why aren't people buying land in the outback, building houses and commuting to their city jobs for 6 hours per day thus making nice profits increasing supply and lowering price?
The outback's a lot further than six hours away from any of the capital cities. It's a lot more than six hours away from even the regional centres where there are almost zero employment opportunities. It would also be cheaper to buy an established house in the bush than to build a new one. The price of new materials and labour doesn't change with location whereas the price of existing real estate does.
Don't know much about Perth, but I helped someone sell a house in Canberra earlier this year, and studied the market there closely. I came away convinced at the time that the housing market is near the top of a fairly big bubble, and while the economic impact of its collapse will not be as serious as it was for the US collapse, housing prices are going to drop quite a bit.
The government was warning people not to get all carried away and buy houses after the first round of mortgage collapse because they were predicting that there would be a second wave of mortgage collapse. People ignored that warning and I guess they'll continue to do so in pursuit of quick profits (when the housing market actually collapsed here after several years of slow decline starting in 2004, one of the numbers released by the ABS was that the average home purchaser holds onto their home for only three years - so most people weren't buying a house to live in for life, they were hoping that property prices would outpace inflation and interest rate rises, as well as assuming that their incomes would only increase).
