Midnight Cobra (WTF)
Trying to get around a system is the way they got themselves into such an enormous mess with basings.
HK Immigration has been pretty clear with them so I don't think what you are suggesting would be considered.
They have already tried it anyway, 0hrs - instructor in ADL then work with FTA for 3 years, then get f*(#$ over by CX when they change the contract on you.
Your plan would only work for Aus residents anyway as the Aus Gov is not going to give a working visa to someone with no qualifications for them to "work" for FTA.
So many holes in your suggestion.
Just remember also that you will never get an Australian base either, from the DFOs mouth.
