Aye Up,
Not enough info in the media article to know how that came about but many (many!) moons ago I did a few stints on an MRT in the Lakes and on a number of occasions turned out to recover people who had walked 'a short distance' from their vehicle,
turned around a couple of times and become completely disorientated, then walked 'back' to their motor in the wrong direction.
It would be interesting to know if a mobile phone nav app was involved in the OP incident as I see more and more people out in the sticks using them - IMHO not wise to rely on.
Some years back now I came across the Bushnell Backtrack - a simple to operate GPS device on which you can set your start location, switch it off and stick it in your pocket/ruck and if you do go adrift you simply switch it back on and select the start point and it will guide you back. (Although it indicates 'as the crow flies' so care re intermediate hazards has to be factored in).
I've used one on my grandson as an intro to full blown GPS and he picked up the use of it in minutes.
Don't get me wrong - not a total substitute for map and compass but that takes time to learn and skill to apply - the Backtrack far less so.

PS The misper was fortunate to be found safe and well - especially at this time of year!
