I'm in Aus to - here it's a hefty fine if you don't vote in local, state and federal elections - our system is different to yours though.
Way ours works you have the candidates and you number them 1 to X
They add up all the number 1 votes and then they exclude the lowest voted candidate and add on the votes for those people at number 2 then 3 then 4 til we have a clear winner rather then just plain "yup I'm voting for that guy"

I have a local council election shortly actually - still not a clue who I want to vote for, I tend to go for the Greens or Independents
