## Political career

On 22 February 2022, Groth, a member of the Liberal Party since 2021, won pre-selection for the Liberal Party in the marginal Labor-held electorate of Nepean, the electorate in which Groth resides. This would allow Groth to contest the electorate for the party in the upcoming Victorian election (November 2022). Groth had told Sky News Australia he was frustrated with the COVID-related lockdowns in Victoria. Groth won the three-candidate contest with seventy-four votes (67%), compared with runner-up David Burgess' thirty-three, and former Bentleigh MP Elizabeth Miller with four. He had the backing of former Victorian Premier Jeff Kennett, Federal Treasurer at the time, Josh Frydenberg, state MP for Brighton James Newbury and former Nepean MP Martin Dixon.

### 2022 Victorian election

Contesting a formerly safe Liberal seat, and one of the most marginal Labor-held seats at the previous election (2018), Groth stood a good chance of regaining the seat for the party. Speaking before the election, Groth stated of his possibility to win the seat: "It's been extremely positive. I'm confident, if we are to have any chance tonight of the Liberal Party and the Coalition getting into government in this state, Nepean is the one that has to turn."
Groth claimed the victory of Nepean the night of the election. After the election, Groth was appointed as Shadow Minister for Youth and Shadow Minister for Tourism, Sport and Events in the Pesutto shadow ministry.
In 2023, Groth voted to expel Moira Deeming from the Parliamentary Liberal Party.

### Deputy Leader of the Victorian Liberal Party

Groth resigned from the Pesutto Shadow cabinet on 13 December 2024, following Pesutto's loss in a defamation case brought by Moira Deeming. This move was criticised by moderate members of the party, with one senior Liberal saying “it spoke volumes about Mr Groth that he had decided to tell the media before his colleagues”, while another described him as a “wanker”.
On 27 December 2024, Groth was elected unopposed as Deputy Leader of the Liberal Party under new leader Brad Battin as part of a broader spill and change among parliamentary leadership.

## Personal life

Groth was born in Narrandera, New South Wales, and grew up in the Riverina area of southern New South Wales. Groth is an avid supporter of the Sydney Swans in the Australian Football League. He was also a member of Vermont Football Club reserve squad during a hiatus from tennis in 2011.
In January 2019 Groth received the OLY post-nominal title at the Brisbane International tournament.
Between 2009 and 2011, Groth was married to Slovakian-Australian tennis player Jarmila Wolfe.
Groth married long-time partner Brittany Boys in 2018. Boys, a Melburnian, was an amateur women's tennis player and competed at the university level for the University of Richmond in the United States. Groth and Boys have two children, twin boys born in April 2021. Groth lives with his family in Blairgowrie, Victoria.
