Cost-of-living relief will be delivered to New South Wales households through a cheaper toll cap, frozen public transport costs and cuts to vehicle registration for one year as the treasurer flags a return to budget surplus is still a year away.Treasurer Daniel Mookhey has delivered his fourth state budget, which posts a $2.3 billion deficit, more than double what was predicted at the half yearly update.In a press conference on Tuesday morning, Mr Mookhey said "if lots of things go right", he predicts the budget will return to a surplus of $1.1 billion next financial year.Against a backdrop of higher fuel prices and global uncertainty, Labor will allocate $561.4 million over 12 months to cap road tolls at $50 a week, freeze Opal card fares and take up to $100 off private vehicle registrations.Opal card price fees are among the big items in the treasurer's state budget.
