The industry is clearly in decline. CASA are just one obstacle to overcome. There are many other things that need addressing to make it right.

I would push this to the extent of pragmatism or whatever you call dealing with Greens and Independents who have nothing left to loose.
That threat alone may help them develop a policy.
