Yawn. A J* cadetship and a RAAF pilot traineeship are not the same thing. Standards, supervision, etc. A newly type qualified RAAF pilot is not the same things as a newly minted J* cadet F/O. Supervision, oversight, ongoing feedback and development, etc. The fact they both fly aeroplanes is about the only thing in common.
Not all cadets are unsafe. A cadet with an attitude that is demonstrated by the type of behaviour you have demonstrated on PPRUNE is unsafe because they think they know it all.
Having done a superior cadet course to the one being offered by OAA (but not as robust as the RAAF) I can tell you that a J* cadet F/O is simply not going to know when they're beyond their skill level.
