I can’t believe the suggestion that Australian airport and airspace infrastructure and management arrangements are anything other than cutting-edge, award-winning, punching-above-our-weight, world’s-best-practice, ICAO-compliant exemplars of efficiency.
I’ve heard rumours that Australia’s airport and airspace infrastructure and management arrangements are considered a joke, internationally, and Australia is called the only third world aviation nation in which you can drink the tap water. But those rumours are - surely - completely unfounded.
(PS: The above is not intended to be a criticism of individual controllers. It’s the system that’s broken.)
