Melbourne has overtaken Sydney as the biggest city of Australia, a title the latter had held on to for more than 100 years.
With populations rapidly growing on Melbourne's fringe, the city limits have been expanded to include the area of Melton, the BBC reported on Monday.
The latest government figures, from June 2021, put Melbourne's population at 4,875,400 -- 18,700 more than Sydney.
The Australian Bureau of Statistics (ABS) defines a city's "significant urban area", by including all connecting suburbs with more than 10,000 people.

"Until the 2021 census definition, the Sydney significant area had a higher population than Melbourne. However, with the amalgamation of Melton into Melbourne in the latest... classification, Melbourne has more people than Sydney -- and has had since 2018, " the ABS's Andrew Howe told the Sydney Morning Herald newspaper on Monday, which described the redrawn boundary as "a technicality".
Proud Sydneysiders will point to the ABS's conclusion that when looking at the greater Sydney and Melbourne regions, Sydney remained bigger in June 2021.
Greater regions of a city take into account its "functional area", the ABS says, and include populations who regularly socialise, shop or work within the city, but may live in small towns and rural areas surrounding it.
However the federal government predicts Greater Melbourne will overtake Greater Sydney in 2031-32.

This is not the first time Melbourne has held the title of Australia's biggest city.
As a result of the gold rush in the late 19th century, which saw migrants flock to the state of the Victoria, Melbourne grew rapidly and outnumbered Sydney until 1905.
