If you can, you you might try and find the ATO from the now closed Geelong Airport, I'm pretty sure he's now driving a GLEX out of Moorabin. I've a copy of the AAT report from all that.(somewhere) It will open up a complete new avenue for you to explore. The CASA FOI in question at the time, was a/ denied entry to an operator on the grounds of his conduct, and b/ denied entry onto a LARGE corporate jet at YMMB for the same reasons.
Cheers
