Folks,
Duck Pilot is spot on.
The Australian taxpayers did a great job in paying for the NZ rules to be put in place in PNG, as the previous Australian rules were considered to be increasingly unworkable, inflexible etc., and not ICAO compliant.
To add to the irony, a bunch of largely ex- AU CAA people did the job, very ably headed by Doug Roser.
Tootle pip!!
