Given that the shambles that CASA appears to have become has occurred over the lifetimes of several parliaments of differing persuasions I don't expect anything of significance to change or, despite the attempts by Sen. Xenophon, anything will be raised in this parliament.
In other words, both sides of politics have aviation skeletons in their closet.
Gobbledock, please understand the first duty of any public servant is to protect their minister from ever having to take personal responsibility for anything that may occur on their watch. However, the responsibility for allowing this situation to be case rests entirely on the public for we haven't demanded any personal responsibility from our ministers for years. We blindly accept the current situation rather than attempting to do anything about it.
