A fireworks display intended to show students at a Steiner school the effect of combustion, has started a large bushfire which forced the evacuation of homes on Queensland's Sunshine Coast.
Noosa Pengari Steiner School principal Janet Molloy says the display for Year Seven students was conducted on Thursday morning by a licensed contractor.
"As soon as the accident occurred all emergency services were contacted and the school's safety procedures successfully activated," she said in a statement.
"We were in constant contact with the authorities during the day."
People living along nearby Grays Road in the township of Doonan, south of Noosa, were evacuated at the height of the drama.
No homes were damaged but a disused caravan was destroyed.
The blaze was burning safely on Thursday night and homes were no longer under threat.
