Thanks to those who given some useful info.
Yes it is for a uni assignment.
No it won't make any form of publication that I know of.
Yes I am a pilot.
I have quite a few stats from the US, but the question specifically asks for Australia.
I have tried the ABS, but the assignment isn't worth enough to fork out a couple of hundred dollars for the specific stats. The beest I have is "employed in air and space transport".
Once again thanks to those that helped.
