All VFR aircraft are required to depart Darwin CTR to the north via Lee Point and Jackos Junction, then via VFR route 1 or 2. Aircraft for Port Hurd, Bathurst Island, Snake Bay or Garden Point may get cleared direct.
Aircraft tracking via the VFR route can expect to be issued an initial heading on departure (e.g. heading 320) on climb to 2,000 ft. Expect to contact Darwin Departures on 123.0 on direction from TWR.
If issued a heading by TWR, maintain that until ATC uses the phrase, ‘Resume own navigation’ at which point they will state where to track next.
