As CASA don't certify simulators, no one can advise you.
CASA does “qualify” flight simulators, which is kinda the same thing as certification, in the simulator world.
Have a look at Subpart 60.B of CASR and the AC for Part 60, hdus001. (Then ask CASA for an estimate of the fee it would charge you to have your simulator qualified. That estimate may be - hmmmm - eye opening.)
