I think that suggesting Australian aviation has done "nothing" is a bit of an overstatement, Jabba.
Lots of people put in lots of work to make well-reasoned, factually-based and constructive submissions to the Senate Aviation Accident Inquiry and the Aviatian Safety Regulatory Review Panel. They were encouraged to put their faith in those processes and are now expecting real action, not the usual empty rhetoric.
We all know who'd prefer to do "nothing" and let things like the regulatory reform Frankenstein continue to gobble up millions and produce thousands more pages of rules that make no substantive contribution to safety, indefinitely. It's not the people who have to pay money to cop this crap.
