1 - Who the heck cares about an Australian backwater?
The possible millions of tourists who travel the area each year, more and more of then will rely on GPS maps in some form.
The worth that happen to me is (on my car GPS) I put in the street but wrong suburb and it took me 10 minutes to realize I was in the wrong area. Even with GPS you still really need some idea of the area you plan to travel and have suitable water/food and fuel for any road trip no matter how short, it's common sense!
