The explosive findings were tabled in state parliament on Wednesday, exposing what the Auditor-General described as a lack of transparency in how the government is financing the controversial SRL.
The levy — applied to every public transport fare across the network — was never publicly disclosed. Commuters have been paying more for train, tram, and bus travel for more than 18 months without knowing the additional charge was being directed to the SRL and other Big Build projects.
The timing of the levy coincides with broader cost-of-living pressures in Victoria, where households are already grappling with rising energy bills, housing costs, and inflation. The secret fare hike is likely to reignite political debate over the SRL’s value and affordability.
Adding to the government's difficulties, the Auditor-General questioned whether SRL East — a 26-kilometre stretch of twin tunnels from Cheltenham to Box Hill — can be completed on schedule or within its current budget. The project is the first stage of the 90-kilometre orbital rail line intended to connect Melbourne’s middle suburbs.
The report did not specify the exact percentage increase in fares attributable to the levy, but the admission comes as a political blow to Premier Ben Carroll, who has defended the SRL as essential infrastructure for Melbourne’s growing population. Carroll has previously suggested the government might pause spending on the project, but has since pushed ahead with construction.
Opposition parties seized on the revelations, accusing Labor of a deliberate cover-up. The Greens and independent MPs are expected to pressure the government for a full breakdown of the levy’s impact on household budgets and total revenue raised.
The government has not yet issued a formal response, but the Auditor-General’s report raises serious questions about fiscal transparency and project governance. With cost blowouts already common in major infrastructure projects, the secret levy may further erode public trust in the state’s ability to manage the SRL effectively.
