As an Aussie, I think you have two main Political Problems, which are at the root of many of the Political Problems you see - why don't you all get started on fixing these first? As an example look how much effort it took women to get the vote in the USA.

1) Lack of Compulsory Voting - I am mortified at the attitudes of pride I have seen from those who boast that they have never voted! This means that the ignorant and stupid are proud of that... and when half the populace won't vote, it's much easier to con those who do.

2) First past the post voting. You have already hinted that you are not unaware of the side effects of this.
