The number of demountable classrooms continues to grow in the Keira electorate and the state government has confirmed it has no plans to replace them.
Figures obtained by Keira MP Ryan Park showed in 2017 there were 57 demountable classrooms, 63 in 2018 and 71 in 2019.
Mr Park said it was clear the government had a plan to deal with growing schools by wasting hundreds of thousands of dollars installing demountables in schools rather than building classrooms.
"Too many children are sitting in second-rate facilities" Mr Park said.
"If our kids are to get the best education we need to provide them with the best possible learning environment, including modern and permanent classrooms.
"Instead of replacing the demountable classrooms in our schools we are seeing more being installed.
"The number continues to grow every year and the government has said they have no plans to replace them.
"We are going to see kids starting kinder next year and the very real possibility they will go through their entire schooling sitting in demountable classrooms."
Parent Elleni Breeze said she was not concerned whether there were demountables at Keiraville Public School.
"I have been inside them and they are neat and clean," she said.
"If they are air-conditioned and are not over capacity then I don't see any issue.
"I would only care if my daughter complained that the demountable was hot and squishy."
Piki McCreedy, agreed, saying her son was in a demountable last year.
"He didn't complain and was happy. That's all I care about," she said.
"I haven't heard other parents say their child complained about being in one."
Mr Park said while some parents may not care, others did.
"If the demountables are modern then they may be alright but if they are old then that is a concern," he said.
The highest number of demountable classrooms were at Wollongong High School of Performing Arts with 13. Waniora and Woonona public schools had seven and six demountables respectively.
The public schools that have five demountables are Austinmer, Corrimal, Thirroul as well as Figtree High.
Keiraville, Pleasant Heights and Russell Vale have four each while Balgownie, Bulli and Lindsay Park have three.
In response to Mr Park's questions on notice, Minister for Education Sarah Mitchell said there were no plans to replace the demountables with permanent classrooms at schools in the Keira electorate.
"Demountable buildings allow the Department of Education to be highly responsive to school needs," she said.
"All demountable teaching spaces are air-conditioned and regularly maintained.
"Where geographically appropriate, a review of catchment boundaries can be undertaken to assist in more closely matching students who live in catchment to permanent classroom supply.
"This may help to reduce the number of demountables at the school area."
Mr Park said the demountables often took up more playground space than traditional classrooms and principals were often unaware if demountable buildings would be staying in their school from year to year, often leading to them being under resourced.
He said he was "disappointed" the government would not consider looking into transitioning old demountables to traditional classrooms.
"There could have been a bipartisan approach to see which demountables urgently needed to be replaced and we could have factored that into the capital works budget."
