Wawa,
Let us be clear about one thing, I have never worked for CASA.
As to what CASA by whatever name has done to destroy Australian aviation --- design, certification and manufacturing in Australia has been strangled, that any have survived surprises me. Victa was driven out of Australia, and they are not the only one, more recently Gippsland were almost destroyed, and they were delivered into the hands of Mahindra. Parts and Component manufacture or overhaul is a dead letter, unless you have an FAA or EASA approval.
Contract pilot training in Australia is a rump of what it should be, the story of what CASA did to China Southern Western Australian Flying School is worth a Senate inquiry. That there is more contract pilot training in NZ than Australia --- what does that tell you??
That heavy aircraft maintenance has almost ceased to exist in Australia ( and don't say "cheap Asian labor" unless you can show that Germany and USA are sources of cheap Asian labor) is largely due to the impossibly uncompetitive regulatory structure. You know that Qantas's biggest new company owned facility, A380 + sized, is in California, do you??
As for what works in producing good air safety outcomes, we do know what works and what doesn't, and "The Australian Way" doesn't.
Tootle pip!!
