One person one vote isn't perfect but any attempt to tweak it gives power to some group to disadvantage another. We fought for this for too long. Universal suffrage is a corner stone of Australian democracy. Start carving out the aged and next will be indigenous, women, people who don't own property and before you know it we are tipping our hats to the aristocracy. Fuck that. People need to engage their brains and read some books and stop jumping on board every distracting opportunity to kick our fellow Australians in the teeth to distract us from the real problems.
