Your entreaties will be ignored by the Government and opposition. That unfortunately is experience. To wit: the recommendations of last years review are ignored.
There are now only Four ways forward in my opinion:
1. Form an "aviation lovers party" get some candidates standing in marginal Federal seats and attempt to frighten the politicians into rewriting the Aviation Act to require CASA to foster Aviation and remove its ability to satisfy its charter by preventing aviation.
2. Wait in misery until a major accident causes a Royal Commission. Then try and get item 1 enacted as part of the process.
3. Financially support political campaigns by aviation minded independents like Nick Xenophon.
4.Civil disobedience, strikes and demonstrations in an attempt to get a positive public reaction.
Items 1 and 3 have the best chance in my opinion.
