The AHIA are working with CASA on a fix for this issue.
Step 1, Currently there are no (Part 142) schools in Australia that can run a MCC Course, but that will change.
Step XX, The other area that might change is the attitude of the customer. What value does holding an ATPL add for single pilot ops?
But since most pilots develop via the off-shore route, they will hold an ATPL well before they get to the Police/EMS role.
