Allegations of cost manipulation and political interference in Melbourne Airport Rail Link route selection

Consensus Summary

Allegations of political interference and cost manipulation in the selection of the Melbourne Airport Rail Link (MARL) route have surfaced in submissions to Victoria’s royal commission, accusing the state government of inflating costs and threatening public servants to favor the Sunshine route. A planning expert’s confidential submission claims a secret working group, established in late 2017 or early 2018, was directed by then-public transport minister Jacinta Allan to ensure the Sunshine route was chosen over alternatives like Maribyrnong. The expert alleged that unnecessary tunnelling was added to the Maribyrnong route, inflating its cost from an estimated $16.5 billion to between $20 billion and $25 billion, while the Sunshine route was estimated at $8 billion to $13 billion. These inflated figures were included in a July 2018 strategic appraisal and later embedded in the 2021 business case, despite the Maribyrnong route being top-ranked in a 2012 study out of 22 possible routes.

The controversy stems from a 2018 election period when the Victorian government, led by then-premier Daniel Andrews, pushed for the Sunshine route despite federal funding of $5 billion announced in April 2018 favoring the Maribyrnong option under then-prime minister Malcolm Turnbull. The Sunshine route was formally endorsed by the state in August 2018, with the federal government following suit three months later. The planning expert’s whistleblowing, delayed for eight years due to fears of professional retaliation, revealed that executives were pressured to align documents with the Sunshine route or face dismissal. A solicitor’s note from August 23, 2018, described the Maribyrnong route as 'doctored to make it unviable,' and the expert calculated that an unnecessary 3.5 kilometers of tunnelling added between $3.8 billion and $4.6 billion to its cost.

Key figures in the dispute include Jacinta Allan, who denied the allegations but pledged to cooperate with the royal commission, and Premier Ben Carroll, who faces pressure from the opposition to explain his knowledge of the events. The opposition’s Evan Mulholland accused the government of 'bullying and intimidation,' while senior minister Jaclyn Symes dismissed the claims as unsourced. The royal commission’s inquiry, established to investigate corruption in Victoria’s construction sector, has already received multiple submissions questioning the integrity of the MARL project. Independent transport planner William McDougall submitted that the Sunshine route was chosen due to 'political interference,' rejecting faster and cheaper alternatives. The Victorian Auditor-General’s Office also criticized the route assessments as 'not sufficiently rigorous' in a 2022 report, highlighting a lack of transparency in the decision-making process.

While both *The Age* and ABC report on the allegations, *The Age* provides a more detailed timeline, including the August 23, 2018, solicitor’s note and the planning expert’s calculations of the true cost of the Maribyrnong route. ABC focuses more on the political fallout, with opposition calls for Premier Carroll to clarify his involvement and concerns about a 'culture of impunity' in government handling of major projects. The Coalition has reaffirmed its commitment to the Sunshine route, citing ongoing construction, while the government has deferred to the royal commission’s findings. The anonymous planning expert’s decision to quit the department rather than pursue whistleblowing through IBAC reflects broader concerns about the risks faced by public servants speaking out against political pressure.

The royal commission’s inquiry is expected to delve deeper into these allegations, with public hearings scheduled to begin soon. The case raises broader questions about the integrity of Victoria’s $100 billion infrastructure program, particularly whether projects like the MARL were driven by public interest or political considerations. The momentum for further revelations appears to be building, as strengthened IBAC powers and ongoing scrutiny may uncover additional instances of alleged misconduct. The outcome of the royal commission could have significant implications for the future of the MARL project and the broader perception of transparency in government decision-making.
