NSW Premier Dominic Perrottet has slammed Prime Minister Anthony Albanese's criticisms of the Liberals' signature Kids Future Fund as "out of touch", a week out from state elections.
The prime minister, who has been campaigning heavily alongside Labor leader Chris Minns, said the superannuation-style fund for the state's children would create a greater divide between rich and poor.
Mr Perrottet, who has previously been complimentary about working with Anthony Albanese on national cabinet issues, lashed out on Saturday saying "he (the prime minister) is absolutely wrong and that is the Labor way".
"There is no greater investment that we can make than in our children's future," he told reporters in the marginal western Sydney seat of Penrith held by former deputy premier Stuart Ayres.
"For the prime minister to come out yesterday and say that he's against, like NSW Labor, setting up a future fund account for our children shows how out of touch he is with the challenges that families are facing today"
"That's why we can't risk...a Labor government in our state," Mr Perrottet said.
Under a coalition government, every child aged 10 and under would have access to a fund with a starting investment of $400.
The Kids Future Fund, would allow parents to make contributions to an account with the government matching payments up to $400, and could see funds grow for some up to $49,000.
The policy, which would cost $850 million over four years, has been criticised for leaving poorer families behind.
Mr Albanese said on Friday "it's certainly not a progressive policy...it just reinforces inequality rather than addressing what is needed".
The premier also said he was "feeling very positive" about his chances of winning the looming election.
He announced a $25 million boost to building boat ramps and jetties statewide, aimed at fishers and families.
Meanwhile, new figures from the Department of Education show the number of demountables used as classrooms spiked to 5093 in April last year, which Labor has seized on as a demonstration of the government's underfunding of public schools.
"The number of demountable classrooms is 30 per cent higher than when the Coalition won office in 2011," said the NSW Teachers Federation's president Angelos Gavrielatos who revealed the figures from a freedom of information request.
The electorates with the highest numbers of demountables were all in Sydney: Riverstone (235), Mr Perrottet's seat of Epping (178), Castle Hill (136) and Kellyville (134),
Labor education spokesperson Prue Car said the jump from around 4000 demountables in 2011 shows the Liberals-Nationals coalition "have comprehensively failed to deliver".
The opposition has promised to build several schools in areas with a fast-growing population, mostly in western Sydney, if voted into government next week.
It also announced on Saturday nearly $18 million to incentivise students to learn a community language on weekends.
A $100 rebate is on offer for parents whose children pass their end-of-year exams and achieve an 85 per cent attendance record throughout the year in the language classes.
"Speaking more than one language is an increasingly valuable skill in a globalised world. Labor's policy will make it easier and more affordable for every child who wants to learn a language to do so," said Mr Minns.
There are 35,000 students studying 60 different languages in more than 250 community language schools across NSW.
Labor also committed to protecting workers in the music industry from sexual harassment and providing those accessing crisis relief services with a total of $6 million over four years.
With one week to go until polls open, early voting centres around the state are expecting strong demand.
Some 4000 centres have opened and will remain in operation through to 24 March, except for Sunday 19 March.
