Mr Smith,
look how terribly wrong it can go, when it does go wrong.

More than enough has been written and spoken on the Australian NAS debacle, and much can be learnt from our Swiss colleagues on their experiences, with the tragic results of failure demonstrated, and now this latest development just further adding to the anx of all involved.
Assuming you still have the ability to provide input to the decision makers, isn't it time to stop the postualtion, chest beating and general grand standing, and take the necessary actions to ensure such a scenario as witnessed in Switzerland does not occur on Australian shores?
"Affordable safety" was a catch cry once attributed to your reform processes. Such a price as experienced elswhere can never be measured.
Do something, and do it NOW.
