WEEKS out from an expected  federal election and sitting MP Anne Webster is the only declared candidate.
The Nationals’ member was early this week without a challenger from the Labor Party and the Greens for the seat she holds with a 19 per cent - the fourth safest seat in Australia.
Under the Coalition agreement, the Liberal Party will again not field a candidate against Dr Webster.
Dr Webster achieved a 3.31 swing at the 2022 election and 49 per cent of the primary vote.
Labor had 16.76 per cent of primary votes while independent Sophie Baldwin and United Australia Party’s Stuart King both outpolled the Greens.
Eight candidates contested Mallee at the 2022 election.
A redistribution last year saw Victoria lose one electorate in the next Parliament left the Mallee boundaries un changed.
Mallee includes Buloke, Central Goldfields, Gannawarra, Hindmarsh, Horsham, Loddon, Mildura, Swan Hill, West Wimmera, and Yarriambiack council area parts  of the Northern Grampians Pyrenees Shires.
A federal election could be called as early as this weekend and is to be held before mid-May.
