The battle for power in NSW is on a knife's edge after two polls suggested the government could lose key seats.

A Daily Telegraph-commissioned poll in two Nationals-held seats suggested the party is 49-51 against Labor in Lismore and against the Shooters, Fishers and Farmers in Barwon.

Another poll, commissioned by the Sun Herald, suggests the coalition trails Labor 49-51 statewide.

Neither poll stated the margin of error.

Premier Gladys Berejiklian will hope her focus on education at her election campaign launch will help turn her chances around.

In a speech on Sunday telling voters NSW deserved to' have it all', she asked to be returned to government so she could "get the job done".

She promised almost an extra billion dollars in school funding and another $2 billion to upgrade two hospitals at the party's campaign launch in Penrith on Sunday.

Opposition Leader Michael Daley also targeted education in his election campaign launch, promising to fully fund public schools with a $2.7 billion education pledge to deliver 100 per cent of the standard level of funding for every student by the end of the Gonski agreement in 2027.

"It means every child will be given a fair chance which is being denied by the Liberals and Nationals government," he told party faithful in Revesby.

It came just in time for those choosing early voting, with pre-polls opening on Monday morning.

Australian Political Studies Association vice president Rodney Smith expects early voting will increase to more than 30 per cent at this election - up from 25.1 per cent at the 2015 poll.
