If I may add something to Creamy's piece.
In lobbying those (possibly) newly elected Senators, please keep in mind that they are going to be like a fish out of water in the political process. As a suggestion, urge them to consult and work with those Senators who now have a working knowledge of CASA and the ATSB (Xenophon et al) who can lead them to what we all hope will be a successful outcome.
It is what I have done in the past and will continue to do. Xenophon is not in my state but I have successfully had my local member consult with him on aviation matters. Now that he has been reelected I intend to further his education on matters aviation.
