Billions on the line: The transport decisions that will define Melbourne for decades

The Allan government must decide by September whether to proceed with tunnelling contracts on Stage 2 of the Suburban Rail Loop — the $35 billion-plus arc connecting Cheltenham to Box Hill — or pause works amid mounting cost pressures and a state budget that recorded a $4.1 billion deficit in May. The decision will set the tone for every other major transport commitment Victoria has on the books.

The timing matters because 2026 was always going to be a crunch year. Construction inflation has eased slightly from its 2023 peak, but labour costs on major civil works remain elevated, partly due to ongoing enterprise bargaining disputes involving the CFMEU and tier-one contractors on government projects across the inner north and western suburbs. Delays don't just push out opening dates — they escalate costs and give political opponents ammunition heading toward the 2026 state election cycle.

The projects in the pipeline — and what's actually moving

Work on the Suburban Rail Loop's first stage, running from Cheltenham to Clayton with stops including Monash University's Clayton campus and the Cabrini Health precinct at Malvern East, is officially underway. The SRL Authority confirmed earlier this year that enabling works along Princes Highway have progressed to schedule. The harder question is what happens north of Box Hill, where the second stage connects to Melbourne Airport — a project that has no confirmed funding envelope and no contracts let.

Separate from the SRL, the Level Crossing Removal Project still has 13 crossings outstanding from its original 110-site program, most of them concentrated in Melbourne's outer south-east along the Frankston and Cranbourne-Pakenham corridors. The Andrews-era target of completing all removals by 2025 quietly slipped; the current government has committed to finishing the program but has not locked in a revised completion date publicly. Each removal now costs between $150 million and $220 million depending on the engineering solution chosen.

Then there's the tram network. Infrastructure Victoria's most recent advice to government flagged that 30 percent of Melbourne's tram fleet will reach end-of-life within eight years. Yarra Trams' contract with the state runs to 2028, and the renegotiation — or potential retendering — of that operating contract is a live question inside the Department of Transport and Planning. A decision to bring tram operations back under public ownership, something the Transport Workers Union has lobbied for, would require legislation and a transition period of at least two years.

Decisions ahead and what to watch

Three milestones in the next six months will signal where the government is heading. First, the mid-year budget update expected in December will show whether the SRL Stage 2 feasibility allocation survives or gets deferred. Second, the tram contract framework review is due to be handed to the minister by October — whatever that document recommends will drive the Yarra Trams negotiation. Third, planning panels for the Doncaster Rail Study, which has been in various states of consideration since the Kennett era, are expected to report by November after community hearings across Templestowe and Balwyn North.

Commuters along the congested Eastern Freeway corridor have been waiting longer than almost anyone for rail to Doncaster. The 2021 federal and state feasibility study costed an underground alignment at between $15 billion and $18 billion. No funding has been committed by either the Commonwealth or Victoria.

For Melburnians tracking these projects, the most practical indicator is the state government's quarterly project status dashboard, published through Infrastructure Victoria's website. The July update, due within weeks, will show which projects have moved from planning to procurement. That shift — from a coloured box on a chart to an actual tender — is the only signal that reliably predicts whether shovels follow.
