A 5-year retrospective analysis of coronial deaths in the 16–40-year age group in the Northern Territory of Australia, 2020–2024

The Northern Territory is the smallest jurisdiction of Australia, with a population of approximately 262,200 people, accounting for <1% of the total Australian population. The Northern Territory (NT) has the youngest median age of all Australian jurisdictions, expected to be 36.3 years by the year 2035–36, as well as the highest proportion of Indigenous Australians, at 30%. This study investigated the manner and cause of death in 430 coronial cases (ages 16–40) between 2020 and 2024. Indigenous Australians were disproportionately affected by death at an earlier age when compared to the non-Indigenous Australian population. Manner of death was predominantly attributed to external causes; suicide by hanging being the most common, followed by accidental deaths, predominantly motor vehicle accidents. However, a significant burden of preventable natural deaths, particularly from cardiovascular conditions, was identified among the Indigenous population. Notably, intimate partner violence was a significant factor in Indigenous female homicides. These findings highlight the critical need for increased awareness, culturally appropriate and targeted public health interventions and enhanced forensic surveillance in the more remote and rural regions of the Northern Territory.
