Vege: NTAW - an ANSETT subsidiary with AN pilots was a joke of an operation.
They had the NT aeromedical service contact for the Darwin region. They had STOL aeroplanes but would only operate into licenced strips - you had to be careful only to get sick or have an accident in near a "licenced strip". Charter boys made a killing (excuse the pun) because NTAW could often not go to where the MEDEVAC was needed. The STOL aeroplanes just did clinic runs to 3-4000' strips! The jokearound the airport was that an NTAW pilot needed an engineer and ground power to start his car on the way home. They were trying to run a mainline RPT operation in the bush.
Don't forget Tillair either, not strictly Darwin but just about everywhere else in the NT. The owner was one of the few to make a squillion in GA - built up a huge company (for GA) and then was wise enough to break it up, sell it off at the peak of the market and sail off into the sunset with the loot. Airnorth still use TL fllight numbers.
