The problem is that no-one really knows how it's going to pan out yet. The intention seems to be to give the studes instruction if the available staff are suitably qualified and it's what they want, otherwise it'll be AEF. My guess is that the UAS will be given a pot of hours to fly (x studes @ 10 hrs) and then the keen beans will do plenty and the others somewhat less.
Instruction will (should) be fairly accessible at some places (eg cranditz where there is a good QFI stock), less so at others. I'm sure that CFS are looking forward to doing the C to I s that will be required and then the maintenance of those quals!
