It was one of five electorates created by the Federal House of Representatives Western Australian Electorates Act 1900, an act of the parliament of Western Australia.

It was a safe seat for the Australian Labor Party and was held by Hugh Mahon throughout its existence.
It was abolished in a redistribution prior to the 1913 federal election and was effectively replaced by the new Division of Dampier.
