I haven't looked through the town thoroughly on google maps so I may have missed a really cluttered property that you saw... but what I did see seems fairly typical of Australian country towns. Australia is geographically, socially and historically different from America. For one thing, we tend very much to towards cyclical drought even when we do take care of the land. For another, we experienced the Cold War Era differently and weren't being told if we didn't clear up mess around our houses they would burn down when we got nuked and it would be all our own fault for not being tidy. Our remote boundless plains with mild temperatures in winter are somewhat less prone to tornadoes that pick up our junk and turn it into missiles. Our sun bakes everything almost sterile in summer, so neatly stacked items of certain sorts can last a very long time outside. Remote towns (Wynarka isn't *really* that remote by Australian standards) tend to be really remote. Why take an old iron bedstead, five old tyres and an old patio birdcage to the official dump, when its going to take half a day to do so and you'll probably be wanting a tyre sometime to put round the base of a tree you've planted... or some wire from that old birdcage to fix a fence? If you don't take the stuff to a formal dump and just find a place to dump it then its still in town and messing up everyone else's views, better to keep it yourself and take responsibility for your own stuff rather than offload it to keep up appearances.
Different places, different ways.
