That's not the answer Mark
The answer is our media is now every bit as much part of the problem as the politicians. They're not the fourth estate, they're now merged with the Third (Commons). Australian subjects have no real say in governance anymore except in those areas where Greens/Independents are their representatives.
Both major parties and the collaborating, desperate media are ignoring them in a grab for unneeded authority based in fear. ALP and LNP memberships are almost non-existent for a reason (except for those who would game the system of course,) nobody with any serious interest in politics outside self-enrichment or a lust for naked power would want anything to do with either party. They're completely divorced from their original philosophical raisons d'etres.
An entrenched and increasingly hereditary political class who have tried to reduce the degree of democracy because it jibes with their authoritarian bent. They don't go into politics without this weird idea they have a god-given right to demand how others live their lives. It's probably a form of psychosis.
I think Douglas Adams had it right when he suggested that anyone who wanted to rule was ipso facto completely unsuited to do so. Perhaps we need to replace the current system with a man with a poor memory living in a small shack answering questions. Couldn't be worse than the current shower.
