Section 16AAC(2) and (3) of the Crimes Act 1914 (Cth) does not mandate a sequential approach of first determining an undiscounted sentence and then applying percentage discounts; a sentencing judge may adopt a more flexible instinctive synthesis approach provided the reductions do not exceed the statutory caps calculated by reference to the mandatory minimum in s 16AAB. The discounts under s 16AAC(3) must be calculated by reference to the period specified in column 2 of the table in s 16AAB (the statutory minimum), not by reference to the undiscounted head sentence — the approach taken in R v Delzotto and Glasheen v R was erroneous in this respect.
