The members of Aussiecon 4 selected Chicago, Illinois, as the host city for the 70th World Science Fiction Convention, Chicon 7, to be held in 2012 in an uncontested election. With only 526 ballots cast, this election had the lowest turnout since records began to be kept in 1974. The voting breakdown was 447 votes for Chicago, 20 ballots expressed no preference, and there were 59 write-in votes for various sites.
