I am part of the millions of Australians who don't vote. About 8% of people living in Australia aren't on the electoral roll. There are also about a million overseas who don't vote. Add to that the informal votes, up from 4% to 6% for the 2010 election and you have about 20% of the population eligible to vote who don't.
For a country that rushed in compulsory voting after the massive drop-out 1922 election (60% turnout), I am proud to announce that we're back!
Not that not voting changes anything. How can it? Voting doesn't change anything. Nevertheless, one should not encourage them. It's poor form.
