Actually Parliament sets the standards (The ACT), CASA and DofT write the rules and generally Parliament rubber stamp them because they don't understand the issues.
It is a typical CASA cop out to say 'but Parliament write the rules' when in fact they invariably write the Regs and put them 'on the table'.
As for foster, there are a few. Go look at

for a start.
Facilitate is a good word though. Facilitate can take into account gaunty's problems with shonky operators without actually shutting down a good operator because of a bit of bad luck. I doubt the current CASA culture can facilitate though.
Facilitate means monitor and point out deficiencies, if they aint fixed take action, either remedial or punitive depending on the record of the operator. Trouble is this action needs to be unbiased. That can't/wont happen while FOI are partners in northern air charter operations, while relatives of CASA employees own businesses that benefit from selective decision making and while the rediculous concept of 'absolute safety' is used to baffle dim witted politicians.
Foster does not mean overlook intentional shonky practice. It means help when a Reg is too complex to understand. It means point out trends while they are fixable. It means understanding that better cash flow means more money for new equipment and better safety standards, but most of all it means understanding that lawyers aren't pilots!
