"In the outback, NDB approaches are the norm at many small airports and World War II-style dead reckoning navigation techniques are still commonly taught and used throughout Australia. Even with the widespread use of satellite navigation, the ability to fly from point to point over featureless terrain with no navigational aids for help is a skill that is likely to serve Australian pilots well for the foreseeable future."
Well maybe the old WWII way but its a well proven method, way and when your GPS,FMC MFD,EADI,EICAS, EHSI,LORAN,RNAV,VOR,ILS,NDB,PAR,TACAN Systems fails DR is all you got left eh?
Try doing it lowlevel in the Desert 500agl DR that will test how good you are.
Sorry my 2 cents worth
