As an observer from afar i'm amazed at the penalty culture that seems to exist in Aus aviation.
As a training Capt., in my airline if this simple incident occurred,( especially with a new crew member) first, check the pilots training record.
Remedial Sim if required and then a few handling sectors under supervision.
A simple handling error, and considering the number of sectors flown by Jetstar not a problem.
Unless of course the bash the LoCo, denigrate the pilots culture that also seems to exist from QF pilots etc.
In UK for example Ryanair/EasyJet crews are held to the same safety/training standards as the Majors, BA/Virgin etc. and not held as some sort of low life!!
