There are parts of Australia where, no matter where you want to fly within an hour or so, you can't get lost. Most of Gippsland is one - you have the great diving range at the top and Bass Strait at the bottom. People who fly there don't even need maps..................but one of our members got lost.
You'd think crossing the Nullarbor to western Australia would be another..........but one person got lost and didn't survive.
I NSW and some other places the E-W boundaries of paddocks run North-South, and flying from Victoria to Queensland the grain towers are an obvious land mark.
However, much of the developed area of Australia requires full nav. equipment and even then there are potholes. On one of my later Navexes with an Instructor testing me, I'd flight planned a turn south of Bendigo, so hardly outback. It was going to be easy the turn was at a Road+Rail Line+Lake on the right. On all previous Navexes I could see the turn points 2 minutes out. This time the turn point wasn't there but looking out to the right I saw the rail line crossing the road and there out to the right was the lake. I made the turn, marked the map, but after about ten minutes my next landmark wasn't there. I could see a rail line and station so I turned off track again and dipped down to read the sign, and was able to get back on my track and home.
