Thanks for the golden info Delta T, I hope it still applies. I'm about to find out.
Given that I have a JAA ATPL and a NZ CPL/IR, if I understand correctly, the best way for me to do this is:
1) Use the TTMRA to convert my NZ CPL to the Aussie one.
2) With an Aussie CPL in hand, conversion from JAA-ATPL to Aussie-ATPL only needs the Aussie ATPL Law exam.
That sounds good to me!
Cheers
