The Western Distributor Project in Melbourne is being funded and delivered by the Victorian government through an unsolicited bid process with no involvement from the Commonwealth. Toll roads are operated on behalf of state governments and are a matter for those jurisdictions. All projects which receive more than $100 million in Commonwealth funding are assessed by Infrastructure Australia, and assessments are released publicly. Information related to project details is commercial-in-confidence in nature, and its release may prejudice Commonwealth-state relations.
