A major government review will look at pricing and signage on Sydney's complex system of toll roads. 

A Treasury document tabled in the NSW parliament during questions on notice states the pricing structure of Sydney's toll roads was allowed to evolve on a case-by-case basis, leading to inconsistencies, inequity and customer confusion.

“While there is a set of ‘Tolling Principles’ that guides the toll-setting process… the current arrangements do not reflect a system-wide approach and incorporate many different charging mechanisms,” the document states. 

An upcoming review will examine pricing inconsistencies, cost-of-living impacts, fairness and equity for road users, as well as the impacts of the toll roads on congestion.

NSW Labor's Shadow Minister for Roads, John Graham, says “the top 10 per cent of drivers are paying more than $6,000 [in tolls] a year”.

“That's simply out of reach for ordinary people doing their ordinary business of moving about the city,” he said.

The opposition wants new signs to be installed at specific toll roads to inform drivers how much they will pay and how much time they will save using the road. 

Similar electronic decision point signs were recently trialled in Victoria, but did not display costs. NSW Labor wants prices included as well as travel times. 

Premier Dominic Perrottet has already cut off the idea, saying newt signs would “create more distractions for drivers”.
