, one vote one value
is a legislative principle of democracy whereby each electorate has the same population within a specified percentage of variance. In the case of the Commonwealth, the maximum variance for the House of Representatives is 10% above or below the mean average. The electoral legislation of The Commonwealth for the House of Representatives
and all states follows the principle of one vote one value with some exceptions.
All states also adhere to the principle. The latest and last was Western Australia in 2007, where the one vote one value principle is now followed in the Legislative Assembly, with the exception that electoral divisions covering an area greater than 100,000km² are allowed a maximum variance of 20%.
