The seat has existed since 1889 and has always been held by conservative parties. The Liberal Party has held the seat continuously since 1970, although the Nationals have provided strong challenges on occasions, such as at the 1999 election when election night figures suggested retired AFL Footballer Paul Couch would win the seat.  Although ultimately Couch failed to finish ahead of the Labor Party candidate and the Liberals Terry Mulder won after receiving preferences from Couch. 
The 2014 Victorian election saw the Liberal's Terry Mulder retain his seat, with a 3.2% swing to Labor. Mulder resigned from parliament on 3 September 2015. The 2015 Polwarth by-election occurred on 31 October, electing Richard Riordan as the new member.
