Several children are seriously injured after falling about 10 metres from a jumping castle that was blown into the air in northwest Tasmania.
Police and emergency services were alerted to a serious incident at Hillcrest Primary School in Devonport on Thursday morning.
"A wind event caused a jumping castle to lift into the air," Tasmania Police said in a statement.
"Several children fell from a height of about 10 metres around 10am and are currently receiving medical treatment at the scene.
"Some serious injuries have occurred."
A rescue helicopter has been sent to the scene, while several police units and multiple ambulance crews are also attending.
People have been told to avoid the area.
The school announced on Facebook it was closing for the remainder of Thursday and asked parents to urgently collect their children.
The school was holding a 'Big Day In' celebration to mark the end of the school year.
