FOUR children died and four others are fighting for their lives after falling 30ft from a bouncy castle caught in a gust of wind.

The tragedy happened after the inflatable was lifted into the air at a school on Australia's island state of Tasmania on Thursday.

Those among the dead include two boys and two girls who were grade 6 students at the primary school.

"On a day when these children were meant to be celebrating their last day of primary school, instead we're all mourning their loss," Tasmania Police Commissioner Darren Hine said.

"Our hearts are breaking for the families and the loved ones, schoolmates, teachers of these young people who were taken too soon.
