From Allegations challenge integrity of Melbourne Airport Rail Link business case

How could the allegations surrounding the MARL route planning affect Ben Carroll?

Possible What happens if… A possibility worth considering, not a forecast.

Allegations challenge the integrity of Ben Carroll's priority airport rail link project Allegations have surfaced challenging the integrity of the business case for the Melbourne Airport Rail Link (MARL), which Ben Carroll has declared his highest priority project. The claims stem from a secret working group, directed by then-Public Transport Minister Jacinta Allan, that allegedly manipulated costings to favor the Sunshine route over the Maribyrnong route. This strategic appraisal, which Transport for Victoria used, was built into the 2021 business case, and the allegations now plunge the project into fresh scandal before the state election.

The facts so far

As reported. Each one links to where it comes from.

  • A secret working group was established at the direction of Jacinta Allan to study four shortlisted routes for the MARL.smh.com.au
  • The planning expert calculated that an unnecessary 3.5 kilometres of tunnelling was included along the proposed Maribyrnong route to add between $3.8 billion and $4.6 billion to the estimated cost.smh.com.au
  • A price tag of $20 billion to $25 billion for Maribyrnong was included in a strategic appraisal published by Transport for Victoria in July 2018.smh.com.au
  • The allegations challenge the integrity of the business case for Premier Ben Carroll’s priority project.smh.com.au

Why it matters

The MARL project is a major infrastructure commitment, involving a $12 billion joint funding commitment by the state and federal governments. For Ben Carroll, whose political platform includes making the airport rail link his highest priority, the integrity of the project's foundational business case is critical to his mandate and political standing.

This issue is part of a wider inquiry into the Big Build, which questions whether the state government's $100 billion infrastructure program was designed to advance public interest or Labor’s electoral prospects. The Victorian Auditor-General’s Office had previously criticized the MARL route assessments as 'not sufficiently rigorous' and lacking in transparency.

What we don't know yet

  • Will the Royal Commission find evidence supporting the allegations of doctored financial estimates?
  • How will the state government respond to the challenges to the business case for the MARL project?
