Tasmania Jumping Castle Accident-AUSTRALIA — Five children have been injured after jumping castles were lifted into the air during two separate incidents in Victoria and New South Wales, as powerful winds swept across parts of Australia on Saturday, September 5, 2026.
The incidents occurred only hours apart, with emergency crews responding to both scenes after inflatable jumping castles were caught by sudden gusts.
Two primary school-aged children were injured at a children’s party in Mount Duneed, near Geelong in Victoria. Later, in Banksia in Sydney’s inner south, another jumping castle became airborne, injuring two preschool-aged children and a baby.
All five children were taken to hospital and were reported to be in stable condition.
The back-to-back incidents have renewed concerns about the dangers associated with inflatable amusement devices during periods of strong or rapidly changing weather.
Mount Duneed Jumping Castle Incident
The first incident happened at a children’s party at a property on Lower Duneed Road in Mount Duneed, southwest of Geelong, shortly before 11 a.m. Saturday.
According to police and emergency-service reports, a sudden strong gust lifted a jumping castle into the air while several children were using it.
Two primary school-aged children, a boy and a girl, were thrown from the inflatable.
Emergency services, including Mobile Intensive Care Ambulance and Advanced Life Support paramedics, were dispatched to the property. The injured children were treated before being transported by road to Geelong University Hospital. They were reported to be in stable condition with upper-body injuries.
Several other children were reportedly on the jumping castle when the incident occurred, but they escaped injury.
The incident happened shortly after a severe-weather warning had been issued for the region, with damaging winds of more than 90 kilometres per hour forecast.
Emergency Crews Respond in Geelong
The emergency response in Mount Duneed involved multiple emergency-service resources.
Ambulance Victoria confirmed paramedics were called at approximately 10:55 a.m. following reports that children had been thrown from the inflatable.
Police and ambulance crews attended the property, while other emergency personnel were also seen at the scene.
The rapid response allowed the injured children to receive medical assessment and transportation to hospital.
Although the incident was frightening for the families involved, the fact that the children were reported to be stable provided some relief to relatives and others who witnessed what happened.
Authorities are expected to consider the circumstances surrounding the incident, including the weather and the way the inflatable was positioned and secured.
Second Jumping Castle Incident in Banksia
Later the same day, another jumping castle was caught by strong winds in Banksia, in Sydney’s inner south.
Emergency services were called to Gardiner Park at about 1:20 p.m. after the inflatable became airborne during powerful wind gusts.
The incident injured three children.
A preschool-aged boy and girl suffered head injuries, while an infant sustained minor injuries.
The three children were treated by paramedics and taken to Sydney Children’s Hospital. Reports said they were in stable condition.
A woman was also assessed following the incident and was reportedly taken to hospital with minor injuries.
Reports indicate the jumping castle was lifted by the wind and moved across the area before coming down near a fence.
The incident occurred as severe weather affected Sydney and surrounding areas, with strong winds contributing to a number of other emergencies across the region.
Five Children Hospitalised in One Day
Together, the two incidents resulted in five children being taken to hospital.
The Mount Duneed incident involved two primary school-aged children.
The Banksia incident involved two preschool-aged children and a baby.
While none of the children was initially reported to have life-threatening injuries, the incidents demonstrate how quickly inflatable amusement equipment can become dangerous when exposed to strong winds.
The fact that both events occurred on the same day has drawn particular attention from parents, community members and safety authorities.
Why Strong Winds Can Make Jumping Castles Dangerous
Inflatable amusement devices can be extremely vulnerable to strong wind.
Although a jumping castle may appear heavy and stable once inflated, its large surface area can allow wind to act on the structure much like a sail.
If an inflatable is not adequately anchored, a sudden gust can lift or move it.
WorkSafe Victoria specifically warns that land-borne inflatable amusement devices can become dangerous when they are not properly anchored. The agency notes that children have previously been killed or seriously injured after inadequately anchored jumping castles were lifted by strong wind gusts.
Workplace safety authorities in Queensland have issued similar warnings, explaining that inflatable devices can become airborne when anchoring is inadequate or when conditions become unsafe.
The risk is particularly concerning because weather can change rapidly.
A party may begin under seemingly acceptable conditions, only for a sudden gust or storm to create a dangerous situation within seconds.
Weather Conditions Under Scrutiny
Weather conditions are expected to be an important consideration in understanding both incidents.
In Mount Duneed, the jumping castle incident occurred while damaging-wind warnings were in effect for the region.
The Bureau of Meteorology had warned of strong winds exceeding 90 km/h in parts of the affected area.
Sydney was also experiencing severe weather conditions, with strong gusts affecting parts of the metropolitan area.
The simultaneous incidents highlight why monitoring weather conditions is particularly important when inflatable equipment is being used outdoors.
Wind forecasts can provide an early warning, but conditions can also change quickly at a specific location.
The Importance of Proper Anchoring
Proper anchoring is one of the most important safety considerations for inflatable amusement devices.
WorkSafe Victoria says operators and suppliers have legal duties relating to the safe installation and operation of land-borne inflatables.
The agency warns that inflatable devices should be properly anchored and that operators should follow relevant safety requirements and manufacturer instructions.
The City of Greater Geelong likewise states that its event risk assessment requirements for jumping castles include information about supervision, Australian Standards, setup and wind management in accordance with manufacturer guidelines or engineering requirements.
These requirements exist because anchoring is not simply a matter of keeping an inflatable in place under normal conditions.
The anchorage system needs to be capable of preventing the structure from becoming airborne when weather conditions deteriorate.
Parents and Event Organisers Urged to Stay Alert
The incidents serve as a reminder that parents and event organisers should take weather warnings seriously when children are using inflatable attractions.
If strong winds are forecast, the safest decision may be to cancel or stop use of an outdoor inflatable.
Parents should also be aware that a jumping castle being properly installed at the beginning of an event does not necessarily mean conditions will remain safe throughout the day.
Weather can change.
Wind speeds can increase suddenly.
Storms can develop quickly.
For that reason, responsible supervision includes monitoring the weather throughout the event and being prepared to stop use of the inflatable if conditions become unsafe.
A History of Serious Jumping Castle Incidents
The latest incidents have also revived memories of Australia’s previous jumping castle tragedies.
In December 2021, six children died and several others were seriously injured after a jumping castle became airborne at Hillcrest Primary School in Tasmania.
A court later heard that the inflatable had been secured using short pegs at only some of its anchor points when a powerful wind event struck.
That tragedy prompted renewed attention to inflatable amusement safety across Australia.
Medical research has also highlighted the dangers.
A 2022 paper in the Journal of Paediatrics and Child Health examined injuries associated with jumping castles and noted the severe consequences that can occur when inflatable devices become airborne.
The latest incidents therefore come against a background of previous warnings about the dangers of wind and inadequate anchoring.
Authorities Investigate the Latest Incidents
Authorities are expected to examine the circumstances surrounding both September 5 incidents.
Important questions may include the weather conditions at the time, how the jumping castles were anchored, whether operators followed manufacturer instructions and whether all relevant safety requirements were followed.
At this stage, it would be inappropriate to assign responsibility without the findings of any official investigation.
The available reports establish that strong winds were involved, but they do not by themselves establish whether any specific person or organisation failed to meet a legal or safety obligation.
Families Await Their Children’s Recovery
For the families involved, the most immediate concern is the recovery of the injured children.
Being thrown from an inflatable amusement device can be an extremely frightening experience for children and parents alike.
The reports that all five injured children were in stable condition provide some reassurance following incidents that could have produced much more serious consequences.
Families, witnesses and other members of the communities involved are now likely to be processing what happened while hoping for the children’s continued recovery.
Community Relief After Frightening Incidents
The two incidents have understandably caused concern among parents and community members in Victoria and New South Wales.
For people who organise children’s parties, school activities, sporting events and community gatherings, jumping castles are a familiar form of entertainment.
The incidents demonstrate that familiar recreational equipment still requires careful risk management.
Inflatables are designed for fun, but they must be treated as amusement equipment with specific operating and weather requirements.

A Reminder About Weather Safety
The two incidents provide a clear reminder that weather conditions should be considered before and during any event involving an inflatable amusement device.
Strong winds can turn a recreational attraction into a serious hazard in a matter of seconds.
Parents, schools, sporting clubs and event organisers should follow manufacturer requirements and relevant safety guidance.
Operators should ensure that equipment is properly anchored and supervised, while event organisers should monitor weather warnings throughout the activity.
When conditions become unsafe, the priority should always be getting children away from the inflatable.
Final Update
Five children have been hospitalised following two separate jumping castle incidents in Australia on September 5, 2026.
Two children were injured after a jumping castle became airborne during a party in Mount Duneed near Geelong.
Hours later, three children, including a baby, were injured when another inflatable was lifted by strong winds in Banksia in Sydney’s inner south.
All five children were reported to be in stable condition after being taken to hospital. A woman was also reportedly treated following the Banksia incident.
The incidents occurred amid severe weather and strong winds affecting parts of Victoria and New South Wales.
Authorities are expected to examine the circumstances surrounding both events, including weather conditions and the safety measures used to secure the inflatables.
For families and organisers, the incidents reinforce an important lesson: weather conditions must be taken seriously whenever children are using inflatable amusement equipment.
Proper anchoring, active supervision and close monitoring of changing weather can help reduce the risk of an inflatable becoming airborne.
The immediate hope is that all of the injured children make full recoveries following these frightening incidents.
