By Drooid · · How we work
Fatal Incident Overview
On 5 October 2026, a Supacat High Mobility Transporter rolled over during a live-fire drill at the Mount Bundey Training Area, Northern Territory. The accident killed Army Corporal Brendan Hannam and injured five soldiers; two remain in intensive care at Royal Darwin Hospital while the other three have returned to Robertson Barracks. Lieutenant General Susan Coyle, Chief of Army, confirmed Hannam was not driving the vehicle.
Background & Context
Mount Bundey is a joint live-fire training site used by the Australian Defence Force and allied forces. The area previously saw the 2017 death of Private Jason Challis, which prompted a temporary pause of live-fire training and a coronial inquest. Earlier in 2026 the ADF also suffered a helicopter crash in the Witsundays and a parachute-training death of Warrant Officer Lachlan Muddle at Jervis Bay, intensifying scrutiny of safety protocols.
