Transurban has six months to renegotiate tolling contracts on almost a dozen motorways it operates in Sydney or have them restructured, after an independent review recommended the NSW government take back control and reduce bills for drivers.

The first independent review of NSW’s toll roads, led by former competition commission chairman Allan Fels, found a new network regime should replace individual tolls on the motorways. The proposed changes, if realised, would benefit drivers commuting from Sydney’s west.
