Sections of the district separated as part of the formation of the Carnamah Road District on 24 August 1923 and the Three Springs Road District on 2 November 1928.
On 1 July 1961, it became a shire following the passage of the Local Government Act 1960, which reformed all remaining road districts into shires.
