There should be one ATPL for the whole world. I thought that if its good enough for ICAO, its good enough for Qantas, BA, CX etc.
I hold 5 ATPL's (as do many of my colleagues), and the Australian was my first one and and was the most worthless one to hold. The exams were the least useful and so far out of date, it was a waste of my time. So please stop thinking "our" ATPL is the only one to have here. We want the rest of the world to except ours if we travel, about time this country caught up with the rest of world.
