The party’s candidate for Albury Ross Jackson said demountables would be replaced with permanent air-conditioned learning spaces.

Billabong and Corowa high schools and Thurgoona and Table Top public school all have demountables, which Mr Jackson said were a “temporary fix”.

“Students in many schools have been stuck in demountables for years,” he said.

About 100,000 NSW students returned to class in demountables this year and Mr Jackson said they made up the learning environment for one in 10 the state’s schools.

“We must provide the best-possible learning environment, including modern and permanent classrooms, to ensure our kids get the best education and start in life,” Mr Jackson said.

He said the Liberal government had rolled the Labor’s replacement program into the school works budget before removing $280 million.

“Thousands of students have been left in demountables with little prospect of them being replaced,” he said.

The state’s 4500 demountable classrooms makes up 10 per cent of all teaching spaces.

And more than 1000 of them have been at the same school for at least 10 years.

Mr Jackson said Labor was taking a long-term view of school needs to deliver the best educational opportunities.

The party plans to spend $100 million over 10 years — on top of the existing works budget — to replace so-called temporary demountable classrooms, libraries and administrative areas.

The member for Albury Greg Aplin said Labor had had 16 years to carry out its demountable replacement plan, so it was “not undertaken with any great rush”.

“In the past four years, this government has spent $30 million creating another 694 classrooms,” he said.

“And I announced $235,000 of maintenance for our schools and that was completed in the school holidays, along with flashing lights in school zones.”

Mr Aplin said the Liberals planned to spend $1 billion for school infrastructure and had a long-term aim of replacing demountables with permanent classrooms.
