State boundary reviews

The boundaries of Victorian State electorates are determined by the Electoral Boundaries Commission (EBC).

Its role is to divide Victoria into electoral regions for the State's Legislative Council (Upper House) and electoral districts for the Legislative Assembly (Lower House).

The EBC is required by law to conduct a redivision if any of the following conditions apply in the period of 18-24 months before the next scheduled State election:

  • enrolments for more than 30 per cent of the districts or regions have been more than 10 per cent outside the average for two months
  • enrolments for more than 25 per cent of the districts or regions have been outside the 10 per cent tolerance and more than 5 per cent of the districts or regions have been more than 20 per cent outside the average for two months
  • there have been two general elections since the previous redivision or
  • the number of districts or regions has changed.

These requirements mean that a redivision has to be held at least every eight years.
