1970 Murrumbidgee state by-election
The 1970 Murrumbidgee state by-election was held on 14 February 1970 for the New South Wales Legislative Assembly seat of Murrumbidgee. It was triggered by the resignation of Al Grassby (Labor) to successfully contest the federal seat of Riverina at the 1969 election.
The by-election was held on the same day as two others in Randwick and Upper Hunter and used the same boundaries as the state election.
