Not absolutely sure of the latest changes Islander jock, but even if you did a CIR renewal, you still need to have the AFR/HFR signed and stamped in your logbook, the concession being that you can use the CIR flight (and a type endorsement) as a BFR flight, but it still must be by an approved AFR/BFR instructor before it can be so used.
To the original Q, I agree with cogwheel and others above, that the review is a review not a test, but that this premise relies entirely upon the standards of the instructor signing it up. Therefore, if any CASA focus is brought to bear here, it should be by ensuring flight instructional standards are clearly defined and achieveable (why do I dream?), not by requiring another test and more paperwork.
IMHO, if commonsense were applied by EVERY AFR/HFR conducting officer, then CASA would not need to review the issue at all.
