Summary information on Elections for the Australian Capital Territory Legislative Assembly

The Australian Capital Territory has had a parliamentary system of government since the granting of representative self-government in 1989 (see 'Sources', below). This makes elections for the Australian Capital Territory Legislative Assembly doubly important; voters are choosing both a representative for their local electoral district, and someone who will support or oppose the current government.

The idea of voting for a representative is straightforward, but running an election for the Legislative Assembly is a complicated process requiring an extensive body of administrative rules. This includes rules about who is eligible to vote and how the votes should be cast and counted. The table below gives a brief summary of the electoral systems used for the Legislative Assembly since 1989, and information on the number of electors on the roll (registered voters), the number of electors in contested seats, the number of voters who cast a ballot, the electoral turnout (the rate of voting in contested seats), and the rate of informal (invalid) voting.
