Marsh was re-elected as mayor by the council on 18 November 2025. State politics Following the resignation of Liberal MP Sam Groth, a by-election was triggered in the district of Nepean. Marsh joined the Liberal Party on 10 February 2026 to seek preselection as the party's candidate in the by-election. He was subsequently given permission by the party's state executive to stand for preselection as he had otherwise not been a member of the Liberal Party for long enough.
The preselection vote was held among 18 members of the state executive and 6 of the local executive, rather than a vote of all local rank-and-file members. Marsh was successful in his bid for preselection. Following his selection as the Liberal candidate for Nepean, Marsh took unpaid leave from his mayoral and council roles, with Paul Pingiaro, the deputy mayor, serving as acting mayor.
During the campaign, Marsh, alongside Liberal leader Jess Wilson, promised to invest $340 million to rebuild the Rosebud Hospital. For a campaign video, Marsh and Wilson filled a pothole in Dromana to highlight a lack of funding for road repairs. This video resulted in a complaint to the Department of Transport and Planning, which ABC News reported was being investigated by the department.
At the 2 May by-election, Marsh was elected as the MP for Nepean. His victory triggered a by-election for the Briars ward.
