No politic talk (ie on TV, radio etc) or polls allowed from 2 days before an election.
One can only vote at one polling place, the closest to your home.
They check ID against their list, Then you grab an envelop, several ballot papers and you go in a small booth closed by a curtain.
I love that you are able to vote anywhere in Australia though. And that you only need to vote once (in France they are usually 2 rounds as its very hard for one candidate to get over 50% votes from the first round)
