NSW Teachers Federation Wagga branch president John Pratt argued the Riverina electorate lost $11 million that was designated for the region's public schools.

"If that money returned to schools, we would see one-on-one teaching, class sizes reduced, students having greater access to resources and teachers having access to specialised training for disadvantaged students," Mr Pratt said.

"We don't want a situation where our most isolated schools, those with high Indigenous or lower socio-economic status areas, are left as a safety net.

"We want to see those schools and kids given the same opportunities as those in the wealthiest schools."

According to the latest Australian government Productivity Commission report on government services, there were 3.8 million full-time students enrolled in schools in 2017, with 65.5 per cent attending government schools.

Labor has promised extra money and has pledged to ensure the federal government takes greater responsibility for public school funding if it wins today's election.

Helen Mundy has two daughters who are attending Wagga High School and argued she would be very concerned if the Coalition remained, because she does not believe they view public school quality education as a right.

"Public schools certainly need more funding and a boost to teachers' funding," she said.

"The issues are that in the last decade, according to Productivity Commission data by the Grattan Institute into government services, public school funding only grew by $155 per student over the decade, while private school students received an extra $1429 per student.

"This is a huge discrepancy and you only have to look at the differences in some of the Wagga schools.

"Private schools have buses, they advertise in papers for students and employ marketing directors; public schools certainly don't have funds to spend on additional things like these," Ms Mundy said.

The state school parent said her vote will be going towards the ALP who will reverse the $14 billion funding that the Coalition has taken out.

"Labor have said they will review and alter the existing federal state agreement, because at the moment state governments are able to decrease the direct funding allocated for student learning," Ms Mundy said.

"They are able to count certain costs that aren't directly related to students' needs, for example transport, capital depreciation and spending on regulatory bodies in their funding model.

"These are funds are not directly focused on students' learning...and this needs to be reviewed and changed."

Ms Mundy argued that both state and federal governments were not being "honest" or fair to public schools.

"With these agreements, at the moment they don't demand the state's compliance with the federal funding targets," she said.

"The Coalition have said they won't alter this, whereas the Labor Party have said they will.

The Coalition does not plan to change school funding policy if it retains government.

However, federal Education Minister Dan Tehan said a re-elected Coalition government would push the states to lift their spending contributions.

A spokeswoman for NSW Education Minister Sarah Mitchell said NSW led the country on school funding.

"[We] recently have committed an additional $6.5 billion for government schools to ensure that every child has the opportunity for a world class education," she said.
