CASA's risk and risk mitigation strategy in so many ways is managed by absolute over regulation. The idea that if there are enough regulations, we can make aviation safe, is just laughable.
Just watch the regulator run for cover if it turns there are systemic factors in this event that could have been mitigated by pragmatic oversight.
This is a terrible tragedy and I hope the senseless loss of life was not in vain if there are lessons to be gained from this..
