The map covers a huge block in the middle of Australia in great detail which has all been field checked in recent years.
From Mount Isa andamp; Julia Creek in Queensland to the Anne Beadell Highway SA / WA border; and from Rabbit Flat on the Tanami Track to Broken Hill in NSW including the Flinders Ranges -- it's all there.
Lots of information includes road classifications and important notations, distances, facility symbols, fuel supplies, camping areas and GPS positions. The reverse of the map is filled with detailed tourist information.
