City of Bunbury: History
The Municipality of Bunbury was established on 21 February 1871. It absorbed part of the abolished Bunbury Road District, which had surrounded the municipality, on 20 January 1950, leading to the formation of a new Suburban Ward. It gained town status on 1 July 1961, becoming the Town of Bunbury, and assumed its current name when it was granted city status on 8 October 1979.
