I am with you that work is needed on airside access "non-flying".
As an aside, I had a beer with RV7 Simon last night - he is working for Rio Tinto at Karratha. Their treatment of it makes CASA look quite gentle.
I have asked him to get me a copy of their literature if possible. My understanding is: One over 0.02 = severe warning. Two = out. Below 0.02 = work but supervisor monitors.
Perhaps the way alcohol and drugs are penetrating the community requires AOD testing - it then comes to how it is managed - I have put to CASA several of the concerns raised for consideration.
