I've just returned from a trip into the Outback. I now have 8400 km (5200 miles) of GPS traces for desert and remote tracks starting with:
Bourke, Tibooburra, Noccundra, Innamincka, Strzelecki Track, Lyndhurst, Maree,
William Creek, Oodnadatta, Marla, Coober Pedy, Woomera, Quorn, Broken Hill.

I also spent a couple of weeks bushwalking in the Flinders Ranges (South Australia) where I collected GPS logs of various tracks around Wilpena Pound and Arkaroola.

It's going to take quite some time to process and mark-up these logs!
