Keith Wolahan (born 30 September 1977) is an Australian former politician and member of the Victorian Bar. He represented the seat of Menzies in the House of Representatives for the Liberal Party from 2022 to 2025. Prior to entering politics, he was an Australian Army officer, serving three tours of Afghanistan as a commando officer, and also practised as a commercial barrister for twelve years.
Wolahan was born in Dublin, Ireland, migrating to Australia with his parents and two brothers in 1988. He was educated at Ringwood Secondary College.
Wolahan studied at the University of Melbourne where he graduated with Bachelor's degrees in Arts (Politics) and Commerce (Economics). He continued studying at Monash University, completing a Bachelor of Law (Honours). He was awarded the Sir Charles Lowe Moot Prize.
Wolahan began his career in law with the national firm, Mallesons Stephen Jacques where he specialised in mergers and acquisitions. In 2010 he became a barrister, specialising in commercial and consumer trials.
In 2013, Wolahan graduated from University of Cambridge with a master's degree in International Relations.
Wolahan joined the military while at University, eventually joining 2 Commando Company, 1st Commando Regiment. Wolahan was promoted to Captain in 2004 and saw several periods of active service, including four postings overseas with 2 Commando:
Wolahan lost two friends in the War in Afghanistan: Marcus Case and Greg Sher. He joined two other Afghanistan veterans in the 47th Parliament of Australia: Andrew Hastie and Phillip Thompson.
Wolahan defeated the sitting member Kevin Andrews in a preselection contest, 181 votes to 111. Andrews entered the contest with written endorsements from then Treasurer Josh Frydenberg, and Prime Minister Scott Morrison. It was the first time a sitting Victorian Liberal MP had been ousted by their members in more than 20 years.
The 2022 federal election saw a 6% swing against the Liberals in Menzies. One of the contributing factors was a large swing in suburbs with higher proportions of Chinese ancestry, including Box Hill and Doncaster.
Wolahan was a member of the House Economics and Joint Standing National Anti-Corruption Commission Committees. He also served as the Deputy Chair of The Joint Select Committee on the Aboriginal and Torres Strait Islander Voice Referendum.
Following a redistribution that shifted Menziesâ margin from a 50.7% Liberal seat to a notionally 50.4% Labor seat, the 2025 federal election delivered a -0.62% two-party preferred swing to Labor in Menzies, resulting in Labor gaining the seat with just over 51% of the two-party preferred vote. He was defeated by Gabriel Ng of the Labor Party.
Just weeks after his 2025 defeat, media reported that Wolahan had been successfully re-admitted to practice at the Victorian Bar.
Wolahan married Sarah Weinberg at Heide Museum of Modern Art in Bulleen. They have two children, Leo and Eva.
