Hi, an interesting post. I fly a large aircraft for an Asian carrier throughout Asia Europe and Australia. Of all the air traffic control systems I fly through, the Australian system is by far the easiest and in my opinion the safest. With data link (CPDLC), ADS and radar combined with the normal ability to use HF or VHF radio, communications and control in Australia are fast and reliable . When you add on board TCAS and GPWS2 and multiple GPS installations. Airline flying with regard to Air Traffic Control has never been safer!
