Way too small control snatch? With a little creativity the RAAF could probably crew the BBJ fleet with reservists and just have a PAF (not you Pass A Frozo) SQN exec. Without too much effort you could possibly extend that expertise also to the Wedgetail and possibly even the KC30B.
With that same creativity (and a bit of sharing between the respective airlines and the RAAF) the only thing the RAAF would probably need to train and check would be RAAF specific skills such as formation flying and type specific issues related to the aircraft role in the RAAF.
I find it surreal that a lot of my tax dollars are spent on teaching a youngling the military way of committing aviation only to send them to the BBJ or 737.
