Created for the 1930 state election, its first member was Edwin Corboy of the Labor Party, previously the member for Yilgarn.
He was succeeded at the 1933 state election by George Lambert, also of the Labor Party, who had been the last member for Coolgardie.
Incumbent member Lionel Kelly then transferred to the new seat of Merredin-Yilgarn.
