The RAAF A330 MRTT (KC-30B) project has been in gestation for several years.
They never expected to go from nought-to-sixty in 9-months.
The very fact that the RAAF are sending guys to QF for line-training means that they acknowledge that they have no experience with the jet and think that it is sensible to accrue some corporate knowledge before setting-up their own operation.
Such contracts are not knocked-up overnight and require diligent "staffing". Again, this is eminently achievable but not within the fantasy timescales that have been suggested.
