Transurban says about 90,000 vehicles may have been misclassified on Victorian toll roads, affecting about 1.4 million trips on CityLink and the West Gate Tunnel. Affected customers will be contacted and refunded automatically, with no action required.

Transurban says it will refund Victorian motorists after a classification error on its tolling system affected about 90,000 vehicles and roughly 1.4 million trips.

Affected customers on CityLink and the West Gate Tunnel do not need to take any action. Transurban said it is contacting customers directly and will reimburse them automatically.

What happened

The company said some vehicles were incorrectly classified in its system, which changed the toll charged on certain trips. The issue affects Melbourne toll roads operated by Transurban under the Linkt brand.

The problem comes after earlier tolling errors in Victoria this year, adding to scrutiny of the company's systems and the way drivers are charged.

Refunds and follow-up

Transurban said it will make an additional payment to customers to recognise the inconvenience caused, on top of the refunds or credits tied to the misclassification.

The company has not yet disclosed the total dollar value of the refunds. It also remains unclear how long the classification error went undetected and which vehicle classes were affected.

The development is likely to renew pressure on Transurban, with consumers and policymakers watching for any response from regulators or government agencies.
