What is the current purpose of this building? It seriously looks abandoned until you look closer.
I see power lines, security lights, the back of a late model Ute. Also weeds from a once loved garden and glad the bush is remaining in charge. My reckoning it is a bait station bivvy holding stock for the conservation volunteers. The security is to ensure people who wander on the track and see this as a place to go/stay/hang out (yep they do). I also see a carved old punga tree stump, there are few of them nearby. It may also be privately owned property. I am going with the conservation theory.
You never know what's lurking in the bush, thanks for looking in :-)
