The Department of Education says it seriously isn't sure how prolonged a southern Wollongong classes are going to be closed, following asbestos was determined in the roof of the classes buildings.
Operate was underway to upgrade the Warilla North Public School as element on the Federal Government's Creating the Training Revolution plan when the asbestos was discovered.
About 120 students from the school will probably be sent to neighbouring schools as a precaution, which includes Mt Warrigal or Barrack Heights.
Education Department regional director, Maria Grace Spence, says air monitoring overnight at the institution has found no airborne asbestos.
"I've just received a phone call to tell me the air monitoring last night came up damaging," she mentioned.
"So there was no airborne asbestos from the classrooms, so that's excellent news."
