New South Wales leaders offer $50 Opal card cap and free transport for kids ...

Hip pocket issues could decide what is shaping up to be the closest New South Wales election contest in a generation.

Transport and child-raising costs have been centre of the election campaign, as more than 5.2 million voters cast their ballot today.

Liberal Premier Gladys Berejiklian has campaigned strongly on public transport projects in Sydney, as her government faces a potential backlash over motorway tolls.

She highlighted this in the final week of the campaign by pledging a $50 weekly cap on Opal fares for train, bus and ferry travel.

Opposition Leader Michael Daley last year promised to allow all school children in the state to travel for free on public transport, estimating this policy will cost $44 million a year.
