A tragic incident at a remote Australian military training ground has left one Australian Army soldier dead and five more injured, marking the second fatality during a domestic training exercise for the nation’s defense force this year. The Department of Defense officially confirmed the accident on Tuesday, revealing the event unfolded on Monday at the Mount Bundey Training Area, a large live-fire military complex located roughly 130 kilometers southeast of Darwin, the capital of the Northern Territory.
This location carries a grim history for the Australian Defense Force: it was the same site where 25-year-old Victorian soldier Jason Challis was killed by a gunshot wound to the head during a 2017 urban assault training exercise. Following the incident, the Department of Defense pled guilty to failing to meet mandatory workplace safety standards. A 2019 coroner’s inquest into Challis’ death later ruled the incident was entirely preventable, labeling the mismanaged training exercise “shambolic”. Challis, who had less than 12 months of service experience at the time, was positioned behind a thin plywood safety barrier when he was struck by gunfire to the head and knee.
Monday’s fatality is the second training-related death of an Australian soldier in 2026. In May, Special Air Service Regiment paratrooper Lachlan Muddle lost his life after a mid-air collision with another jumper during training at Jervis Bay Airfield in New South Wales, falling to the ground after the impact.
Emergency response teams acted quickly to evacuate the five injured service members following Monday’s incident, Northern Territory Chief Minister Lia Finocchiaro confirmed in statements to the Australian Broadcasting Corporation (ABC). According to Finocchiaro, two injured personnel were airlifted by helicopter to Royal Darwin Hospital by 7:30 p.m. Monday, with an additional three transported by fixed-wing aircraft roughly two hours later.
“Our entire community’s thoughts and prayers are with the bereaved family, who are obviously devastated by this terrible loss,” Finocchiaro said. “Our full support stands with all our service personnel, who are feeling this loss immensely right now.”
Northern Territory Police Commissioner Martin Dole told the ABC that local law enforcement has deployed specialized resources to the Mount Bundey site to support the official ongoing investigation being conducted on behalf of the coroner. “We cannot yet comment publicly on the cause of the injuries to defense personnel,” Dole said. “At this stage, we are fully assisting with the coronial investigation.”
The Department of Defense has requested that media and the public respect the privacy of all affected soldiers and their families as the investigation progresses.
