As a CAO 82.5 operator Tiger would already be conducting CRM/human factors for RPT training. This was recognised in the recent MCC exemption as being very similar to the MOS standard for MCC training. In their CAR 217 command upgrade programme they'd be doing a LOFT style test and an IPC. So the cost to them is minimal. And if you had to do retraining....really, they take that risk with every pilot they hire.
I believe CASA has been working with quite a number of operators to build the ATPL test into their command training programmes. I have a CASA mate in SYD who was involved in briefing the operators.
