Deputy opposition leader resigns, accuses colleagues of leaking damaging information

Sam Groth quits politics in a dramatic announcement that has unsettled the Liberal Party less than a year before the state election. The former tennis player and deputy opposition leader said family pressure and internal leaks forced his hand, delivering a public rebuke of colleagues as he walked away from Spring Street.

Groth’s statement made clear he felt betrayed by people inside his own party. He said the “public pressure placed on my family in recent months has been significant” and that discovering some of that pressure “came from within my own party” made continuing impossible. His decision came on 5 January and was described by rivals and commentators as a significant blow to the Liberals’ stability.

How the resignation unfolded

The announcement followed months of scrutiny. Earlier in the year questions were raised about Groth’s use of a taxpayer-funded vehicle for travel and a separate legal dispute involving media reporting about his personal life. Those matters were public and resolved in his favour, but the internal dynamics of the party appear to have been decisive.

“I have always tried to approach this job with honesty, hard work and a clear focus. But when you find yourself having to fight against your own team, it becomes impossible to put those interests first.”

Groth recontested the deputy leader role late last year, suggesting he intended to stay engaged in politics. Instead he chose to step down, citing family welfare and the difficulty of working amid apparent factional infighting.

What colleagues said and party response

Party leader Jess Wilson said the issues raised were historical and not matters she planned to reopen, attempting to frame the resignation as settled business rather than systemic dysfunction. The statement drew an immediate rebuttal from Groth’s camp and commentators who said the timing and tone revealed deeper rifts within the opposition.

Within hours another senior Liberal, long-serving MP Wendy Lovell, also announced her retirement after 24 years. That second departure increased concern about the party’s readiness for a campaign that is now less than ten months away.

Electoral implications

Groth won his seat from Labour in 2022 with a strong swing, making it one of the Liberals’ few gains at the last election. His exit leaves that seat vulnerable. Political analysts say independent and teal candidates could seize the opportunity, potentially narrowing the Liberals’ path back to government.

With preselection and campaign preparations already underway across the state, losing an incumbent deputy so close to polling day raises practical questions about candidate selection, fundraising and messaging at a critical moment for the opposition.

Over the last year Groth faced media scrutiny for the use of a taxpayer-funded vehicle and for allegations about his personal life reported by a newspaper. The family launched legal action over one set of claims and the case settled in Groth’s favour out of court.

While those matters were resolved, Groth said the leaks and internal disputes — including threats of legal action and party members “knifing” one another — made it untenable for him to continue. The public airing of these tensions has sharpened questions about the party’s discipline and internal culture.

What this means for voters

The immediate effect is political uncertainty in Groth’s constituency and a reputational hit to the Liberals ahead of the state election. For voters, the resignation raises questions about party cohesion and whether internal disputes are distracting from policy and service delivery.

Opposition strategists will need to act quickly to shore up support in affected seats and to present a united front before campaigning intensifies later this year.

Who is Sam Groth and what role did he hold?

Sam Groth is a former professional tennis player who entered state politics and won his seat from Labour in 2022. He rose to become deputy opposition leader before resigning in January, citing family pressure and internal party leaks.

Why did Sam Groth quit politics?

Groth said the decision was driven by sustained public pressure on his family and his belief that some of that pressure was generated from within his own party. He described ongoing factional disputes and legal threats among colleagues as making it impossible to prioritise public service.

What impact does his resignation have on the Liberal Party?

The resignation weakens the Liberals just months before a state election, putting a previously safe or marginal seat at risk and exposing internal divisions that opponents can exploit. A second senior MP’s retirement on the same day intensified concerns about party unity and electoral readiness.

Will there be a by-election or immediate replacement?

The timing and procedure for replacing an MP depend on formal resignation processes and decisions by the party. With an upcoming state election, the party may choose a speedy preselection process or to time replacement decisions to minimise disruption to campaign planning.

How should voters interpret these events?

Voters should view the resignations as signals of internal turbulence within the opposition, and consider how party cohesion might affect policy delivery and campaign credibility. Local issues and candidate quality will remain important in affected electorates.

Key takeaways

  • Sam Groth quits politics citing family pressure and internal leaks.
