The most visible damage is in the building at the corner of Wellington and Henry St, with the Henry St corridor and the section wrapping around to the school oval visibly gutted by flames.
It is unclear on viewing the damage from the outside what impact the fire has had on the rest of the connected corridors and classrooms.
