Shire of Gnowangerup: History
Gnowangerup was initially gazetted as the Gnowangerup Road District on 26 January 1912, taking in territory that had been part of the Broomehill and Tambellup road districts. On 23 June 1961, it became a shire following the passage of the Local Government Act 1960, which reformed all remaining road districts into shires. On 4 June 1982, the eastern half of the Gnowangerup shire was excised to form the Shire of Jerramungup.
