Australian Bouncy Castle Accident – Devonport Tragedy Details

On December 16, 2021, a routine end-of-year celebration at Hillcrest Primary School in Devonport, Tasmania transformed into one of Australia’s most devastating peacetime disasters. A sudden, violent wind gust—later characterized as an extremely rare meteorological event—lifted a jumping castle and zorb balls dozens of meters into the air, catastrophically injuring and killing multiple children who had been playing inside. The incident prompted an extensive police investigation, criminal proceedings against the equipment operator, and nationwide scrutiny of inflatable safety standards at public events.

Six children, aged between 11 and 12, died from injuries sustained in the accident. Three additional children survived but sustained serious injuries requiring hospitalization. The operator of the equipment, Rosemary Anne Gamble, who operated under the business name Taz-Zorb, faced a single charge of failing to comply with a workplace health and safety duty. After a criminal hearing lasting approximately two weeks in late 2024, a magistrate acquitted Gamble in June 2025, concluding that while safety failures occurred, they were not the substantial cause of the tragedy given the unprecedented nature of the wind event.

The Devonport bouncy castle accident generated widespread public mourning, renewed calls for stronger event safety regulations, and an outpouring of community support for the affected families. Prime Minister Scott Morrison visited the site days after the incident, pledging federal funding for counseling services. A community fundraiser accumulated more than $1.4 million for the families, though distribution was delayed due to legal complexities. The tragedy prompted immediate regulatory action, with Tasmania’s Department of Education prohibiting all inflatable equipment on school grounds.

What Happened in the Australian Bouncy Castle Accident?

The accident occurred during the final day of school celebrations at Hillcrest Primary School, a small public school serving the Devonport community in northern Tasmania. Students had gathered for an end-of-year event that included a jumping castle and zorb balls set up on the school grounds. At approximately 10:30 a.m. local time, a sudden gust of wind—subsequently described by witnesses as resembling a “mini tornado” or “dust devil”—struck the area with enough force to lift the unsecured inflatables off the ground.

• A sudden, unforeseeable wind gust caused inflatables to become airborne at Hillcrest Primary School
• The jumping castle and zorb balls were lifted approximately 10 meters before children fell to the ground
• Seven children were inside the jumping castle at the time of the incident
• The wind event has been classified by expert witnesses as a “Black Swan” occurrence—extremely rare and impossible to predict
• The operator secured only four of the eight anchor points recommended by the manufacturer
• No manslaughter charges were filed against the equipment operator
• The incident triggered immediate bans on inflatables at schools and public events across Tasmania

Victims and Casualties from the Devonport Tragedy

Children Who Died in the Accident

Six children succumbed to injuries sustained during the accident. Five children died at the scene or shortly after emergency services responded. One additional child, Chace Harrison, survived the initial incident but died three days later on December 19, 2021, succumbing to injuries sustained in the fall.

The victims ranged in age from 11 to 12 years old. They were identified as Addison Stewart (11), Zane Mellor (12), Jye Sheehan (12), Jalailah Jayne-Maree Jones (12), Peter Dodt (12), and Chace Harrison (11). The children’s names were released by authorities following notification of all families and in consultation with parents and guardians. The victims were students at Hillcrest Primary School, a close-knit educational community where the accident sent shockwaves through families, staff, and the broader Devonport population.

Injuries to Surviving Children

Three other children present at the jumping castle sustained severe injuries but ultimately recovered. These children required hospitalization and ongoing medical care following the incident. Emergency responders treated multiple casualties on scene before transporting the injured to medical facilities in the region. The nature of injuries sustained from a fall of approximately 10 meters included traumatic blunt force trauma consistent with such high-impact events.

Legal Charges, Trial Proceedings, and Verdict

The Charges Filed Against the Operator

Rosemary Anne Gamble, trading as Taz-Zorb, faced a single criminal charge in connection with the incident. The charge, filed in Devonport Magistrates Court, alleged that she failed to comply with a workplace health and safety duty under Tasmanian occupational health and safety legislation. The prosecution argued that Gamble failed to adequately secure the jumping castle according to manufacturer specifications, using only four anchor points instead of the recommended eight.

Notably, no manslaughter charges were filed against Gamble despite the deaths of six children. Prosecutorial decisions regarding homicide-level charges are typically informed by assessments of culpability and foreseeability. The charge pursued reflected what authorities determined could be substantiated based on evidence available at the time of charging decisions.

Criminal Hearing and Defense Arguments

The criminal proceedings commenced with a hearing lasting approximately 10 to 14 days beginning in November 2024. Gamble entered a plea of not guilty to the single charge. During the proceedings, the defense team presented expert meteorological evidence characterizing the wind event as an unforeseeable “Black Swan” occurrence—a term used in risk management to describe extremely rare events with severe consequences that are only recognizable in hindsight.

Defense arguments emphasized that even full compliance with anchor requirements may not have prevented the inflatables from becoming airborne given the unprecedented force and nature of the wind gust. Expert witnesses for both prosecution and defense provided conflicting assessments of whether the wind event could have been reasonably anticipated or prepared for. Rosemary Anne Gamble was visibly emotional during court proceedings as graphic details of injuries sustained by the children were read into the record.

Magistrate’s Verdict and Reasoning

On June 6, 2025, Magistrate Robert Webster delivered his verdict, acquitting Rosemary Anne Gamble of the charge. The magistrate acknowledged that failures in securing the equipment occurred, noting that only four of eight recommended anchor points were used. However, Webster determined that these failures did not significantly expose the children to additional risk because the wind event was of such an unprecedented nature that it could not have been predicted or guarded against through standard safety measures.

The ruling effectively concluded that while substandard anchoring practices were documented, they were not a substantial contributing cause of the deaths and injuries given the extraordinary meteorological circumstances. The verdict drew immediate criticism from families of the victims, who expressed that the outcome failed to acknowledge the full measure of their loss and did not hold anyone accountable for the preventable aspects of the tragedy.

Safety Failures, Anchoring Issues, and Regulatory Response

Anchoring Deficiencies Identified

Investigations revealed that the jumping castle operated by Taz-Zorb was secured using only four anchor points, falling short of the eight anchor points specified in manufacturer instructions. The prosecution argued that this failure to follow recommended safety protocols constituted a breach of workplace health and safety duties. Manufacturer guidelines for inflatable equipment typically mandate specific anchoring configurations based on equipment size, expected wind conditions, and surface type.

The magistrate’s findings acknowledged the partial anchoring failure but distinguished between procedural non-compliance and causation. Evidence presented indicated that gust winds of the intensity experienced on December 16, 2021 represent statistically anomalous meteorological conditions for the Devonport region. Anemometer data and weather records from the area did not show conditions that would have triggered standard weather warnings or prompted event cancellations under existing protocols.

Regulatory and Policy Changes Following the Incident

Tasmania’s Department of Education responded to the tragedy by immediately prohibiting all inflatable equipment on school properties statewide. This ban extended to jumping castles, inflatable slides, and similar devices at all educational institutions under departmental jurisdiction. Numerous other organizations and event organizers across Australia subsequently adopted similar restrictions, voluntarily or through updated organizational policies.

While the incident prompted widespread cautionary measures, comprehensive legislative reforms specifically addressing inflatable equipment safety were not detailed in available sources. The tragedy exposed gaps in existing regulatory frameworks governing temporary inflatable installations at public events, though policy development remained ongoing as of the available information. The case has been referenced in discussions regarding the adequacy of current standards for equipment anchoring, weather monitoring requirements, and event organizer responsibilities.

Documentation of the Devonport tragedy leaves certain facts established with confidence while other questions remain open or unresolved:

Community Response and Lasting Impact

The Devonport community and the broader Tasmanian population responded to the tragedy with collective grief and offers of support. A GoFundMe campaign established in the immediate aftermath raised more than $1.4 million for the Hillcrest Community Fund, intended to support families of the victims. However, distribution of these funds was delayed until March 2022 due to legal complexities surrounding the management and allocation of donations following a fatal incident. This delay drew criticism from families who felt the council was unresponsive during their time of profound loss.

The psychological impact extended beyond the directly affected families to include first responders, school staff, and community members who witnessed the aftermath. Of the 174 emergency responders who attended the scene, approximately 12 remained on mental health leave by the one-year anniversary of the incident, reflecting the traumatic nature of the response and its lasting professional impact.

Planning for a permanent memorial to honor the victims was under consultation as of May 2023, with the school and council working to determine appropriate form and location for a lasting tribute. The physical and emotional scars of the December 16, 2021 accident continue to shape the Hillcrest Primary School community and the wider Devonport area, influencing how similar events are now approached, regulated, and remembered.
