The Australian democratic system of government works best when elected representatives, your members of parliament, are made aware of issues that affect you personally!
Tell your member of Parliament what's affecting you, and what you want the solution to be.
Consider sending a CC copy to your local MP and Leader of the Opposition for their information.
You can vote for them if they make you happy, or you can vote for somebody else!
