Keg, of course there is a long involved process through which the chosen ones are put. This "train the trainer" course is, itself, usually run by internally trained trainers. The feedback loop is self confirming and the facade is complete. Like anything that involves appeasing casa (FRMS, SMS, engineering etc.) it's a box ticking exercise and done on the cheap.
No offence to the many great, naturally talented and caring training captains out there, but as a rule Australia is pretty bad at this training stuff.
