All 3 agencies are waiting for it to happen, get it out of the way so to speak. I mean, it's inevitable right? The reason it hasn't happened so far is luck.
When it does happen the country will be plied with examples of it happening overseas and it was inevitable that it was going to happen here, just a matter of time. and that we need to get used to the fact that you can't eliminate all risk. The airspace system will then need to change to increase safety. Maybe then privatised towers will be allowed with an appropriate level of renumeration for the level of traffic and complexity. Real world economic decisions can then be made about commission/decommission. You know, punters decide that Byron is a ****hole and they'd rather holiday at King Island, close the tower.
