Education will be a key part of Mr Daley’s speech with the opposition leader to pledge $2.7 billion to fully fund public schools and bring them in line with the Gonski commitment.
The extra funds will mean 100 per cent of the standard level of funding for every student is delivered by 2027, according to the Sun-Herald.
Mr Daley will also announce that if elected, Labor will introduce nurse-to- patient ratios in mental health units in the state’s hospitals.
While Sunday’s events may signal the beginning of an official launch, campaigning has been under way for months as leaders battle it out in a bid to win over voters.
A recent poll indicates Labor leads the coalition 51 to 49 per cent on a two- party preferred basis with Mr Daley ahead of Ms Berejiklian as preferred premier.
The UComms/ReachTel poll, published in the Sun-Herald on Saturday, also shows the coalition’s primary vote has dropped to 28.7 per cent while Labor’s remains steady at 34.1 per cent.
Debate during the campaign has centred around spending on Sydney stadiums with the premier under scrutiny for splashing cash on the demolition and reconstruction of Allianz Stadium.
Ms Berejiklian has argued the government was spending close to $90 billion on other infrastructure in NSW and also insisted education funding wasn’t suffering.
Michael Daley has threatened to sack members of the SCG Trust’s board that oversees the Moore Park sporting facilities.
