Chimbu that was the advice of one of the RAAF people involved in the whole affair who related the saga to me at a mess night. They apparently took some student from the plastic parrot and gave him a drive and he was somewhat "surprised" by the PC9.
My limited understanding of the PC9 is that it was positioned as a lead in to jets and is was not designed to be a particularly docile and forgiving aircraft, in fact mirroring jet behaviour as I was told.
