Former navy diver Ashley Semmens, who suffered from PTSD following a traumatic event, attempted suicide in 2020.

A study for the Royal Commission into Defence and Veteran Suicide shows an ADF member seeks emergency suicide help every four hours.

The study indicates over 1600 veterans had suicide-related engagements with authorities in Queensland from 2014 to 2017.

Veterans often do not report mental health issues for fear of losing their employment, leading to untreated suffering.

Research counters the belief that continued service in the Defence Force reduces suicide risk, affirming a direct correlation between ADF service and suicide.

The royal commission is expected to present its final findings by September 9, with support available for individuals in crisis or needing counseling.
