John,
Looking on Google Earth, I see that the "gaol" is still there and interestingly, the present day roads to the NW, including one called Hinkler Crescent, follow the old dispersal taxi-tracks. I guess Darwin Council wasn't going to look a gift-horse in the mouth, when they were laying out a new suburb in 1946.
The old main runway is now Ross Smith Avenue and the hangar is still there, opposite Qantas Park.
