A new specialist trauma institute dedicated to improving the treatment of children caught up in mass casualty events is set to open at Sydney Children's Hospital, Randwick, directly inspired by the experiences of medical teams who fought to save lives during the Bondi Beach terror attack.

The New South Wales Institute for Paediatric Trauma will bring together paediatric surgeons, nurses and other specialists to share critical knowledge and skills with medical professionals across the country, with the facility expected to be operational within the next six months.

Surgeons speak out about the night they tried to save Matilda

For the first time, paediatric surgeons who operated on young Matilda during the Bondi Beach terror attack have spoken publicly about that devastating December night. Paediatric surgeon Guy Henry described the event as deeply difficult for all involved, while also highlighting an extraordinary show of dedication from hospital staff.

"What was incredibly special were the staff who came in who were not on duty," Henry said.

Henry said the experience had sharpened his understanding of just how different treating children in trauma situations is compared to treating adults — a principle that will sit at the heart of the new institute's training programs.

"Children are not small adults," he said. "They have different physiology, they have different anatomy and so that has to be taken into account."

The Bondi terror attack left a profound mark on emergency and surgical teams across New South Wales, and the institute represents a determined effort to ensure those hard-won lessons are not lost.

Bondi Junction stabbing also shaped the institute's creation

The new institute was also shaped by the response to a separate tragedy — the stabbing attack at Bondi Junction the year prior, during which medical teams treated the nine-month-old daughter of victim Ashlee Good for serious stab wounds. That incident further underscored the need for dedicated, specialised training in paediatric mass casualty response.

Training, simulations and national impact

The NSW Institute for Paediatric Trauma will run mass casualty simulations and expert-led training sessions designed to strengthen the response to, and treatment of, children involved in major trauma events — regardless of where in New South Wales they are located.

Funding for the institute will be drawn from both the state government and donations channelled through the Sydney Children's Hospitals Foundation. NSW Health Minister Ryan Park said the institute would deliver benefits not only to children across New South Wales but across Australia more broadly.

Guy Henry and his colleagues are now set to channel the lessons learnt on that devastating night into a national training resource — ensuring Matilda's legacy endures in the form of better-prepared medical teams and, ultimately, better outcomes for the youngest and most vulnerable patients in future mass casualty events.
