Cardiff, Western Australia
Cardiff is a small rural town in the Shire of Collie in Western Australia’s South West. It sits about 170 km south of Perth, 55 km from Bunbury, and 10 km from Collie. The town has a population of about 118 people (2021) and the postcode is 6225.
History and name: The area’s townsite was identified in 1902. The nearby Collieburn townsite was gazetted in 1907, but by 1915 land needs moved toward Cardiff. The Cardiff Progress Association asked to rename the town, and the southern part was officially renamed Cardiff in 1916 (it was first called Collie-Cardiff; the hyphen was dropped in 1944). The name comes from the Collie coalfields and the coal city of Cardiff in Wales.
Heritage: Cardiff has 17 heritage-listed sites, including the former Cardiff Mine Site, the Cardiff Public Hall, and 14 heritage-listed houses.
Mining and Lake Kepwari: Cardiff’s coal mine operated from 1900 to 1960, south of the town and connected by a railway to Collie. The mine pits later filled with water, and the largest pit is now Lake Kepwari, a local recreation area.
Indigenous land: The area sits on the traditional lands of the Kaniyang and Wiilman people, part of the Noongar nation.
