The ACT is the only Australian jurisdiction to make extensive use of electronic voting. All pre-poll voting centres use electronic voting equipment, though paper ballots are available for the technology challenged. The six pre-poll voting centres are also used as election day polling places with electronic voting available. In all 20% of votes at the 2008 election were recorded electronically. A total of 43,820 electronic votes were recorded, though only 42,668 were formal votes. The rate of informal and discarded electronic ballots was 2.6% compared to 4% for paper ballots. The electronic voting system guides voters through the numbering sequence, so you cannot make a mistake filling in your ballot paper without being prompted that you have made an error. This means that an informal electronic vote is a deliberate informal, as a voter cannot vote informal without over-ridding the warning message.
