I continue to research:
Statistics for all flights in Australia the month of
54.5 % of all international flights in Australia were by ADS-B approved aircraft.
–
20.5% of all domestic scheduled flights were by ADS-B approved aircraft.
– 16.6% of ALL FLIGHTS in Australia were by ADS-B approved aircraft.
And Cathay, Army, RFDS, Rex, UPS all have ADS-B applications in progress.
This "unproven orphan technology that Australia is going to lead at its risk" seems to be ...... catching up with Australia
