OK... He was an experienced bushman, and as Ded Driver said, "lost rescue 1.01 ..... when stuck up ship creek, stay up ship creek with your sunken ship..."
But he left it - you'd think he'd know this well, living in WA, and most probably heard about a lot of rescues/deaths over the years. And he didn't have a PLB/EPIRB?
He also left a sign pointing east - but he wasn't in that area... Why did he do that, if he wasn't going that way?
It just sounds strange to me...
