It doesn't affect airlines like Qantas because CASA doesn't have the capability to regulate them anyway.
Sunny,
Not true, since what CASA did to Ansett, and more recently almost destroying Tiger.
CASA's mad dog approach to going public with a baseball bat labeled "safety", has got the airlines bluffed, they are very wary of dealing with "the regulator" in a way that I didn't see in all my years in the RPT business.
Particularly in engineering, quite unbelievably silly "new" interpretation of regulations have been costing them a motza.
All to the benefit of foreign carriers.
Tootle pip!!
PS: Mind you, CASA has got a couple of non-ICAO "was invented here" lulus lined up for FAAOC holders. Nothing like spreading the misery.
