Four children have died in a freak jumping castle tragedy during an end-of-year celebration at a primary school in Tasmania.
Four other children remain in a critical condition and one is in a serious condition.
Police confirmed the children killed were grade six students, including two boys and two girls.
The children fell an estimated 10 metres after the jumping castle they were in was picked up by a powerful gust of wind.

The accident took place during an end-of-year celebration at Hillcrest Primary School in Devonport, in the state's north-west.
Tasmania Police Commissioner Darren Hine said an investigation was underway into the incident and the Coroner had visited the scene of the tragedy.
"On a day when these children were meant to be celebrating their last day of primary school, instead, we are all mourning their loss," Mr Hine said.
"Our hearts are breaking for the families and the loved ones, schoolmates, teachers, of these young people who were taken too soon.
"Our thoughts are also with those emergency services personnel who attended to try and save these people's lives."
A report will be prepared for the Coroner in conjunction with WorkSafe Tasmania.
Premier Peter Gutwein described the tragedy as "devastating and heartbreaking for all involved".
"It's difficult for me to find the right words in such tragic circumstances," he said.
"I'm certain that I speak for all Tasmanians next tending my deepest sympathies to the family, friends and loved ones of everyone affected by today's tragedy.
"For the five children who remain in hospital, our thoughts and prayers are with them and their families and their friends during this very difficult time.
"On a day when school children were celebrating at the end of term so close to Christmas, it's simply inconceivable that this shocking incident has occurred."
A vigil has been set up at the Devonport Uniting Church, about 2.5 kilometres from the scene, with several locals turning up to light candles in tribute to the children.
Police are asking people to avoid the area to allow emergency services to respond.
"There has been an accident on site at our school," a post on the school's Facebook page read.
"We are closing the school for the rest of the day. We ask that parents come to collect their children as a matter of urgency."
Today is the last day of Term Four in Tasmanian public schools.
Police and emergency services remain at the scene.

"It just breaks your heart."
