The latest redistribution of electoral boundaries ahead of the November 26 poll was released last week.
Murray Plains, held by Nationals Leader Peter Walsh, retains the same boundaries as it had for the 2018 election.
The Murray Plains electorate, which features towns such as Echuca, Swan Hill, Kerang and Rochester, was created due to the abolition of the districts of Swan Hill and Rodney, and first contested at the 2014 election.
In 2014, Mr Walsh enjoyed a two-party preferred vote of 72.40 per cent and increased that dominance to 73.95 per cent in 2018.
New electoral boundaries will affect approximately 21 per cent of voters at the 2022 Victorian election.
The new boundaries are the result of the state redivision conducted in 2021 by the Electoral Boundaries Commission, in a consultative process that invited submissions from the public, political parties and any interested groups.
This was the first redivision of both houses of Parliament since 2013.
“The VEC has updated the register of electors with the new district and region boundary changes,” Electoral Commissioner Warwick Gately said.
The changes formally come into effect on Tuesday, November 1 (Melbourne Cup Day), when the writs for the Victorian election are issued.
