hainguen830,
A post has already alluded to post that refers to possible limitation at Ansett Flight Training.
It can actually go a bit further than that, I am aware of one case where a candidate for an INITIAL issue of a CIR had to negotiate a Legislative Instrument with CASA to allow him to do an initial in a simulator, and not an actual aircraft.
Given that CASA policy and recent changes to CAOs are all about using more simulation, not less, there are some serious contradictions.
Do your homework very carefully. Using a 320, you may find it cheaper to do the FAA license and endorsement, and the FAA Multi/Land/Instrument ATR is a lot more useable/commercially attractive.
Tootle pip!!
