RJ555,
Not trying to defend our 'mates' at CASA, but this entire CAAP is old info - that is well in need of updating (the CAR, CAO etc that it refers to have been rolled into Part 61).
Our new Part 61 is much more like the FAA system (at least a lot more than it used to be!!)
The problem for our 'mates' is that there are so many industry issues with the new CASA Part 61, I think updating this CAAP will be a low priority (mainly because it works in principle and also it affects a small population).
My take on the new CASA Part 61 is that a IPC can be conducted in an FAA sim, just not the initial instrument rating; which I think is fair enough (ie CASA retains control of initial issues, as the FAA/TC does) 'renewals'
can be done by contracting states.
