The CASA response is CFIT.
Simple as that.
No need for further discussion.
CASA have told you that it is CFIT.
Stop arguing.
ATSB says it is CFIT with a few buts.

1. Do not fly an RNAV approach unless you are rated.
2. Do not fly any approach above the max IAS for your CAT.
3. Do not allow an unqualified FO to sit beside you.
4. Get real and follow the instructions.
5. At least try to do a pre-approach brief.
6. The first time you bust the rules probably won't kill you, but it will lead to the death of your pax one day.
