Username. This accident was clearly caused because RAAF requirements prohibit civilian pilots from planning and flying the safest way down the coast .
The pilot got safely to Taree from the border at night. A night VMC flight is normally flown in VMC and it's known that Williamtown was CAVOK that night.

S1 responds that the clearance will not be available because Sydney control area is not Night VMC (Night Visual Meteorological Conditions - in other words a pilot must fly visually and clear of cloud).
So Dick, lets assume that the aircraft had received a clearance via O/H Williamtown, Sydney ATC Sector1 said that their airspace wasn't VMC. What airspace would the aircraft have used and how would the aircraft navigated between WM and BK? Remember CAVOK is nil cloud below 5000ft.
