Sydney’s biggest toll operator will not freeze price increases during the coronavirus pandemic, arguing the revenue is funding projects that are keeping people employed during the crisis.

Prices on a handful of Sydney toll roads are set to increase from Wednesday, prompting calls from the NSW opposition for a stay on the indexed mark-up amid the economic downturn.

Opposition roads spokesman John Graham said the government needed to work with toll operators to freeze price increases for the quarter, and possibly beyond.

“NSW is in a precarious economic position right now and we need to look at different ways to ease the financial burden on families and businesses,” Mr Graham said.
