Yes you're right about the CAO, there is provision to fly ME NVFR Charter in an aircraft that is NVFR equipped, but, under the auspices of a CIR. Untangling IF recency is an interesting path for this NVFR privilege;
CAO 40.2.1 - sub-section 14 (page 15)
Para 14.1 - a particular grade of command instrument rating authorises the holder of the rating to fly an aircraft of the category concerned within Australia as pilot in command, or co-pilot, using the navigation aids endorsed in the holder's personal logbook in the following circumstances:
(a) - private and aerial work flights under the night VFR procedures, provided the pilot meets the aeronautical and recent experience requirements applicable to a night VFR endorsement.
(b) - Charter flights under the night VFR procedures, provided the following aeronautical and recent experience requirements are met
This goes on to list the NVFR requirements.
Anyway, it was suggested on non pax carrying positioning flights that your opportunity will exist.
Note that I suggested you ask to have issued a PIFR when you get the CIR.
Similarly, it will let you accrue some useful IFR hours and approaches (Company permitting you) on private category positioning flights.
Your PIFR is valid for two years, no recency on any aids, and can be automatically renewed by virtue of a CIR renewal.
All it costs is the current CASA clerical fee, used to be $15, probably now either $65 or $130 on top of the CIR, ask for it concurrently with the CIR.
All CIR aids need to be added as "FPA's", same thing.
It is worth reading up about this, it does have it's uses, but do the CIR first.
