Morningside State School students have been warned they'll be turned away at the gates this morning, after a massive blaze destroyed a quarter of the school campus this morning.
Emergency crews were called to the heritage listed primary school just on 3am, arriving to find at least three two-storey classroom buildings completely ablaze.
It took more than 50 firefighters from at least 13 crews to bring the blaze under control, despite heavy rain pelting down at the time.
QFES Chief Superintendent Lance Duncan said a large section of the campus is unstable.
"We've got three buildings that were interconnected and they were reasonably large structures," he said.
An exclusion zone has been set up around the school boundary.
Some nearby homes were evacuated, while residents in the surrounding areas have been told to keep windows and doors closed due to the thick smoke.
Initially, there had been fears the smoke was toxic.
"We're wetting down the asbestos and ensuring that it didn't get airborne in the local area," said Duncan.
"We also brought our scientific officers in to conduct air sampling in the area to ensure the safety of the local residents."
