For more than a century, Sydney has been Australia’s biggest city, but Melbourne has snatched that mantle on one key population measure thanks to a boundary change.
The Australian Bureau of Statistics uses several methods to calculate urban populations, including the Significant Urban Area classification, which includes all contiguous urban centres with more than 10,000 people.
An update to the bureau’s geographical boundaries following the 2021 census quietly changed Melbourne’s Significant Urban Area to include the district of Melton on the city’s northwestern fringe. That amalgamation lifted the population of the Melbourne Significant Urban Area to 4,875,400 in June 2021 – 18,700 more than Sydney.
