I agree with Creampuff. Until the politicians decide to move, nothing can be done. Once the terrible state of CASA and ATSB becomes the subject of a Cabinet minute, anything and everything can be done, and quickly because the good folk at PM &C will supervise, and they are smart, fast, and don't take BS from anyone.
The goal of Mr. Mrdak and his department, CASA and ATSB is to remain underneath that radar.
Albanese doesn't care about aviation except so far as it provides opportunities for property deals and access to the Chairmans lounge. The Department will move mightily to try and maintain that laissez faire approach in a new Liberal Government.
My guess is that they will send a message that appointing a "troublemaker" like Sen. Fawcett will cause the government grief by distracting them from the main game, etc. etc. You know how it goes - make aviation reform a "second term priority" blah blah.
It remains to be seen what Abbott does, but I haven't got my hopes up.
