The Victorian government, led by Premier Jacinta Allan, is under increasing scrutiny following a recent Resolve Political Monitor poll indicating a dramatic drop in support for the state Labor party.

The poll revealed that the party's primary vote has fallen to a historic low of 22 percent.

In light of these numbers, Allan is facing pressure to seriously consider a $2 billion funding boost from the federal government aimed at reviving the Melbourne Airport rail link project.

This offer is part of the Albanese government's efforts to advance the project prior to the upcoming federal elections.

The project, initially supported with a $5 billion commitment each from both federal and state governments, was put on hold under the leadership of former Premier Daniel Andrews but is now back in the spotlight.

The additional funds are designated for the expansion of Sunshine station, facilitating connections between the airport rail link and existing suburban and regional networks.

Despite Canberra's willingness to contribute further to the airport rail project, the Victorian government remains undecided.

Premier Allan has advocated for additional federal funding to instead be allocated to the Suburban Rail Loop (SRL), a priority project for her administration.

Infrastructure Minister Catherine King has emphasized that funding for the airport rail link is independent of the SRL.

The decline in Labor's popularity in Victoria is strategic for the Liberal Party, which plans to exploit the apparent unpopularity of Premier Allan by linking her image with Prime Minister Anthony Albanese in upcoming campaigns.

Internal Liberal polling suggests such an association could adversely affect the Prime Minister's support in Victoria.

This comes amid stalled federal campaigning in key marginal Liberal-held seats, with releases from sources indicating that the Labor party is being cautious in their approach to these areas.

Opposition Leader Peter Dutton is optimistic about gaining seats in Victoria, targeting the eastern and outer suburbs of Melbourne as battlegrounds where Labor has been dominant.

Victoria's Deputy Premier, Ben Carroll, has publicly supported Premier Allan, dismissing any immediate threat to her leadership despite the poll results.

However, the state's Labor insiders acknowledge the urgency to reassess their strategies as the party prepares for an upcoming by-election in the crucial seat of Werribee.

The seat has been a Labor stronghold since 1978.

Labor insiders suggest that to reverse the current trend, the party must engage with pressing issues such as rising living costs, crime, and substantial state debt.

Additionally, there is a growing sentiment within the party that Premier Allan must distinguish herself from the legacy of her predecessor Daniel Andrews, especially concerning significant infrastructure projects like the SRL.
