The SRL “fix is in”

If you want proof that Infrastructure Australia (IA) is another politicised agency, look no further than Victoria’s Suburban Rail Loop (SRL).

Across multiple public evaluations and media reports, IA highlighted three core problems with the SRL: unreliable cost estimates, a weak business case, and major delivery risks. These concerns were serious enough that IA warned governments to “proceed with caution” and even prepare exit strategies if the project proved unviable.

IA’s concerns fell into five clear categories:

1. IA repeatedly stated it had “low confidence” in the Victorian government’s $34.5 billion costings for SRL East, which haven’t been updated since 2001.
2. IA said the business case lacked the level of detail required for a project of this scale, particularly around cost-benefit analysis, demand modelling, and the project’s economic returns.
3. IA “questioned the financial viability” of the SRL, especially against other infrastructure projects.
4. IA warned that SRL East’s risks extended beyond the first stage, and cost blowouts in SRL East would jeopardise SRL North and SRL West (stages 2 and 3).
5. IA noted a $9.3 billion funding gap in the SRL East business case and recommended that the Commonwealth restrict its $2.2 billion commitment to “tangible elements” such as land acquisition or enabling works.
