A trek usually around woop woop which has little or no goal other than admiring nature, and the personal satisfaction of walking around the middle of nowhere and making it home alive.
Usually the recount of the trek is exaggerated to add extra excitement and trill. The trek in actual fact is usually very dull.
Walkabout's really have no logical reason or appeal other than to combat boredom with adventure. Many people who participate in walkabout's are usually told their "crazy" and "are gonna get themselves killed one day".
benj: I just got back from a walkabout northern NSW
dazza: Tell us about it
benj: Well, I was walking down past Eungella and saw this huge brown belly on the side of the road, didn't see it until I was right over it, bit me leg, thought I was a goner, but these hippies came by and took me to the hospital, bloody life savers, they are!
dazza: You're a bloody legend
