The 1920 Ballaarat by-election was held on 10 July 1920 to elect the member for Ballaarat in the Australian House of Representatives. [1] [2]
At the 1919 federal election, Nationalist candidate Edwin Kerby defeated the sitting Labor MP Charles McGrath by a single vote, the narrowest margin in Australian electoral history.
