One controller, only, who insists that "when ready leave control area on descent" is a mandatory readback. It's not a level assignment therefore it is my interpretation that it is not a readback requirement.
You are correct - it is indeed the cancellation of a requirement (to maintain a level in CTA) and the cancellation of requirements do not require a readback - visual approach used to be the same till they amended the requirment to readback type of approach (!)
It's 10 years now since the changes in readbacks were introduced in Oz and both pilots and controllers still cant get it standardised! Blame CASA for the failure to provide appropriate education I say!! Those that don't understand or don't care default to reading it all back regardless and that was never the intention!
