Shire of Westonia: History
The Westonia Road District was established on 30 June 1916. On 1 July 1961, it became the Shire of Westonia under the Local Government Act 1960, which reformed all remaining road districts into shires.
In April 2012, residents of the Shire rejected a proposed merger with the neighbouring larger Shire of Yilgarn, with 82 percent of voters opposing the merger.
