In my humble opinion most military ATC, couldn't organise a root in a brothel.
The last time I went into Williamtown, visual through 10,000' and happy to take a visual approach with no other traffic, but oh no get vectored out for the ILS which added another 20 minutes to the flight time.
Similar to Darwin in the late 80's, two or three VFR aircraft and you would be held OCTA at Wildman Lagoon or wherever, round and round in circles.
Always reckon if Darwin RAAF ATC been on duty in February 1942, the Japanese Imperial Air Force would have been held north of Bathurst Island as clearance to enter CTA or the CTR would not have been available.
