At the time of the incident, five children were playing inside the bouncy castle. Out of these, four boys, aged between 9 and 13, were transported to the hospital with injuries that were thankfully not life-threatening, as reported by 7 News.

According to News.com.au, the boys sustained injuries to their arms, backs, and shoulders. Fortunately, all of them are currently in stable condition.

A spokesperson from the jumping castle company said the owners told him there was a “massive wind” caused by a “freak tornado,” according to The Daily Telegraph. 

Along with the bouncy castle being blown away, the spokesperson said the wind also “ripped away” a generator. 

Wind gusts of up to 45mph had been recorded in nearby Canterbury, and 55mph at Sydney Airport, according to 9 News. 

The incident is under investigation by SafeWork New South Wales, a workplace health and safety regulator, according to the Australian Broadcast Company.
