Yes its another snake, but this one is not from Central Australia. I snapped this last week while on a short holiday to the top end of the Northern Territory: the little town of Mataranka to be precise. It is a 'night tiger', the wonderfully evocative name given to this particular colour variety of the extremely dull-named brown tree snake (Boiga irregularis). We found this guy sitting in the driveway of the Caravan Park we were staying at. A night drive through the town and surroundings turned up two other individuals so I guess they are pretty common in the area.
The species is venomous, though not dangerously so and rear-fanged, nonetheless I decided against picking up this mature individual. In case you weren't aware, this is same species as the introduced treesnake that has been wreaking environmental havoc on the island of Guam.
