The pupils, who are temporarily based at Wee Waa Public School, had again been falling ill following the relocation of demountable classrooms and equipment from WWHS.

The items which are believed to have been causing the issues have now been replaced.

Despite the potential contamination of those items, the DoE is holding strong on its assertion that everything being repurposed from the high school has passed strict safety checks.

"Buildings and furniture relocated from the high school site to the primary school have been comprehensively cleaned and results from tests conducted by an independent hygienist confirm there is no evidence of out of the ordinary moisture levels and other factors to suggest any health-related concerns," a department spokesperson said.

"Since the high school was temporarily relocated to the Wee Waa Public School site, the department has been monitoring both schools.

"This will continue to maintain the safe working and learning environment for staff and students."

A criticism that was levelled at the NSW government by Barwon MP Roy Butler was that the Department of Health was not taking an active enough role in the case and that they should be the lead authority on the matter.

However, the DoE have rejected that sentiment, stating that NSW Health had been heavily involved.

"NSW Health have been involved since the beginning of these incidences and helped develop an action plan to support both staff and students whilst a further investigation of reported health concerns continues," the spokesperson said.

"Anyone experiencing reactions should inform their school immediately.

"The school and community have done an excellent job during this time and the department will continue to support them and the principal."

While nothing has been confirmed as of yet, the potential for a new Wee Waa High School being built is ramping up as a Project Reference Group has been set up by School Infrastructure to inform the planning process.

This is a very early step in what would be a long journey should a new school be approved, with the DoE having stated a "timeline for construction can be determined following NSW Government and statutory planning approvals".
