We had our local federal MP Luke Howarth (Lib with a small margin) here at YRED in sunny SE QLD a couple days ago to give him our aerodrome's 2 bob's worth and ask for his support for GA - which he unsurprisingly guaranteed.
AOPA also arranged for Allan Bligh to come up from Sydney especially for the meeting. Damn good effort and he certainly got the message across to Mr Howarth that the problems we outlined are representative of the whole country.
Hopefully the wheels will turn. Luke may not be able to do too much directly because he doesn't have the power.
But maybe, just maybe, he will get the opportunity to blow in the right ear now that he's got our message loud and clear.
