The City of Cairns, in Far North Queensland, was originally established as a borough with a chairman from 1885 until 1903, when the Local Authorities Act 1902 transformed it into a town with a mayor. The town achieved city status in 1923. In 1995, when the Shire of Mulgrave amalgamated into the City, the mayor was elected by a much larger base of voters. In 2008, when the City was amalgamated with the Shire of Douglas into the Cairns Region, the mayor's voter base expanded yet again.
