Truscott airfield is owned by the local indigenous community but managed on their behalf by a Darwin Company.
As far as visiting goes, there is no public accommodation or food available. Neither is there any available transport or anyone to drive it, there is avgas, but you have to buy the whole drum. What is there is for the working helo and management crews only, there is no local shop, everything comes by barge from Darwin. That is most probably why it appears to be expensive to visit.
Yes it is a great place to visit, working there though is something else again.
