Factional conveners from Victorian Labor's left and right met on Sunday night, July 26, 2026, and agreed that Premier Jacinta Allan no longer commands the support of a majority of the Labor caucus, setting the stage for a leadership challenge just four months before the November state election (The Guardian; ABC AM). The Age described the gathering as an "extraordinary" and "emergency" meeting of Labor chiefs (The Age).

Allan has publicly rejected the pressure. She declared she is "not going anywhere" in response to the leadership speculation in late July 2026 (ABC News). Attorney General Sonya Kilkenny, a key Allan supporter, dismissed the leadership speculation as "idle gossip" on July 26 (The Guardian).

Deputy Premier Ben Carroll is identified as Allan's most likely opponent for the leadership. Carroll indicated to colleagues he would only run for the position if it were vacant, rather than actively challenging Allan (The Guardian). That conditional stance is consistent with Carroll's public posture from June 15, 2026, when he ruled out a leadership challenge at a press conference and stated he supported Allan "to be a world-class premier and get re-elected in her own right" (The Guardian).

One option discussed at the Sunday faction meeting was for a group of ministers to approach Allan on Monday, July 27, to inform her she had lost colleague support. The hope among factional figures was that Allan would stand down ahead of a formal vote during Tuesday's caucus meeting, the first day of parliament after the winter break (The Guardian).

If Allan does not stand aside and instead contests a leadership ballot, the entire Victorian Labor membership would also receive a vote in a weeks-long process under rule changes introduced after the Rudd-Gillard-Rudd era at the federal level. Those membership ballot rules have never been tested in Victoria (The Guardian). An untested process launched four months before an election would inject significant uncertainty into Labor's campaign preparations.

The momentum for a spill had been building before the June 2026 winter break, driven by poor polling, Allan's weak personal approval ratings, rising One Nation support, and concerns over her response to organised crime infiltrating Victoria's Big Build infrastructure program through the CFMEU construction union (The Guardian). The Big Build, a $100 billion infrastructure program (The Guardian), was overseen by Allan during her tenure as minister for transport infrastructure before she became premier. She has rejected growing calls for a royal commission into organised crime infiltration of the program (The Guardian).

Allan had been attempting to get ahead of the corruption issue. The Sydney Morning Herald reported on July 23 that she planned to unveil a plan on Monday, July 27, to root out Big Build corruption and target organised crime, and that she hoped the plan would save her leadership (SMH). Whether that announcement survives the factional maneuvering now underway remains an open question.

The leadership trajectory has been visible for months. On March 19, 2026, Allan dismissed leadership speculation as "scallywag" behaviour, with senior Labor MPs publicly declaring their support the same day (ABC News). In early June, Labor MPs reviewed increasingly negative election odds, reigniting speculation (The Age). On June 9, Allan vowed to "see it through" (ABC News) and dismissed the rumblings as "navel-gazing" amid a surge in One Nation support (The Age). She warned of the "chaos" that would result from a One Nation government in Victoria (The Age). Prime Minister Anthony Albanese endorsed Allan in approximately June 2026, describing her as the sole person capable of leading Victoria (Sky News Australia/Facebook).

Allan became the 49th premier of Victoria in September 2023, elected unopposed following the resignation of Daniel Andrews (The Guardian). Carroll became deputy premier at the same time (The Guardian). If elected leader, Carroll would immediately call for a royal commission into organised crime and the Big Build, work to resolve the public school teacher pay dispute, and seek to improve the party's economic credentials and standing with the business community (The Guardian).

The broader context here is a party running out of runway. Allan's most consequential vulnerability, the Big Build corruption file, is also the one most personally tied to her: she oversaw the program as minister before inheriting the premiership. Carroll's pledged response, a royal commission, directly inverts Allan's refusal to call one. And the factional consensus that she has lost caucus support, reached in an emergency meeting described as "extraordinary" by The Age, suggests the internal arithmetic has shifted decisively since June, when Allan's allies could still mount a public defence. The untested membership ballot rules add a structural wildcard: if Allan refuses to stand aside and forces a ballot, the process would consume weeks that Labor can ill afford with an election in November. A party that once dispatched a leader in Daniel Andrews and installed his successor unopposed now faces the prospect of a protracted, membership-wide contest under rules designed to prevent exactly the kind of backroom maneuvering that is now unfolding.
