How we ranked suburbs
The method
We compared each suburb's population in the 2016 and 2021 Census, counted where people usually live, on the ABS's 2026 suburb boundaries. Only suburbs with at least 1,000 people in 2016 are ranked, so a handful of new homes can't top the list. Suburbs are ranked two ways: by growth % and by the number of new residents. 427 suburbs in Western Australia met the rules.
