On your point #1
Surely the best way to get meaningful representation would be to run a senate candidate for "The Hangar Party" in every State?
If never-has-beens like Lambie and Ricky Muir can get into the Senate, strong aviation proponents would get in for sure IF EVERYONE IN THE INDUSTRY GOT BEHIND THEM.
The last 30 years have demonstrated that the Senate cross-benches can hold the Parliament to ransom; first the Australian Democrats, then the Greens, and now this rabble of unrepresentative swill.
I am certain, however, that any "party-room unity" in the Hangar Party will be destroyed by the same marginal factional in-fighting as we see on PPRuNe.
