Class 5 requires no check-up with any medical professional of any kind - not even a GP! I realise that's the same as RAAus, but isn't this a step too far? Perhaps designed to fail so CASA can say to GA in general "we gave you what you asked for and look what happened!"??
So what are you going to say when it doesn't fail?? Besides the fact that CASA would NEVER give the industry something for nothing and wait for it to fail so they could take it back.
That's like trusting a truck driver to not be sleep-deprived and high on drugs before he crashes, killing four police officers... but never mind. Let's go!
You need to loosen the grip a little mate.
