The incident happened on Monday, October 5, at the military training site south-east of Darwin. The Department of Defence confirmed the death on Tuesday and said the soldierâs next of kin had been notified.
Five other soldiers were taken to Royal Darwin Hospital. Northern Territory Chief Minister Lia Finocchiaro said two injured personnel were evacuated by helicopter at about 7:30pm, while three others were flown to hospital at around 9:30pm.
Emergency response followed reports of a vehicle accident
Emergency services were alerted on Monday afternoon after reports of a vehicle accident at the training area.
Australian media reports have identified the vehicle involved as a Supacat high-mobility transporter, citing Defence sources. However, the Department of Defence has not yet publicly explained how the incident happened or confirmed the precise cause of the soldierâs death.
That means key details remain under investigation, including whether the vehicle rolled, collided with another object or was involved in another type of accident.
The Department of Defence said one soldier died and five others were injured, adding that further information would be released when possible.
Police assisting Defence investigation
Northern Territory Police have sent officers to Mount Bundey to assist Defence and investigate the incident on behalf of the coroner.
NT Police Commissioner Martin Dole said authorities were not yet in a position to comment on the cause of the injuries.
Major crash investigators are also involved as authorities work to establish the sequence of events and prepare information for the coroner.
Reports indicate two of the injured soldiers were critically hurt, although Defence has not released individual medical conditions.

Mount Bundey is a major military training site
The Mount Bundey Training Area is regularly used by the Australian Army and allied forces for large-scale exercises, including live-fire training and vehicle operations.
The location is one of several strategically important military training areas in northern Australia, where Defence conducts demanding exercises designed to prepare personnel for operational conditions.
Australia has also been investing in broader defence capability across the region, including surveillance infrastructure such as the Jindalee Operational Radar Network.
While live-fire training takes place at Mount Bundey, there is no evidence at this stage that live ammunition was involved in Mondayâs fatal incident.
Training ground has history of fatal incidents
The latest death has renewed attention on safety at Mount Bundey.
Australian Army Private Jason Challis was killed there in 2017 during a live-fire urban training exercise. A later coronial inquest examined serious failures surrounding the exercise, and Defence subsequently pleaded guilty to failing to comply with a health and safety duty.
The circumstances of Mondayâs incident are different and remain under investigation, but the earlier case adds significance to the latest fatality at the same facility.
Second Australian Army training death this year
The Mount Bundey tragedy follows the death of Warrant Officer Class Two Lachlan Muddle from the Special Air Service Regiment during parachute training at Jervis Bay in May.
Muddle died after a mid-air collision with another paratrooper, who survived with minor injuries.
That incident added to broader scrutiny of the risks involved in high-intensity military training. Similar dangers have also been seen outside the ADF, including a separate fatal mid-air skydiving collision.
Key details still to be confirmed
Defence has not yet publicly identified the soldier who died, the unit involved or the specific training activity underway at the time.
Authorities have also not confirmed the exact cause of the accident, whether equipment failure played a role or whether training at Mount Bundey will be suspended or changed.
Those questions are expected to form the focus of the investigation as Defence, NT Police and the coroner examine how one soldier was killed and five others were injured during the exercise.
