Coroner's Finding: Williamson, Colin George

72y · Male·Severe head and chest trauma sustained in a tree-felling accident; multiple severe traumatic injuries including flailed chest, two significant cranial fractures and subarachnoid haemorrhage

Colin Williamson, aged 72, died from severe head and chest trauma sustained during a tree-felling accident on his friend's property. He was struck by a falling tree branch while operating a log splitter. Critical failures included inadequate tree-felling technique (insufficient scarf cut, uneven back cut, no hingewood for directional control), lack of formal training in tree-falling competencies, and use of an outdated safety helmet manufactured in 1994 that was non-compliant with current Australian Standards and had failed straps. While Williamson had 30 years of informal chainsaw experience and a lapsed licence, he had never undertaken formal training in tree-felling techniques. The coroner emphasised that formal training completion would have identified and prevented the technical errors made. Regulatory reform requiring chainsaw operator certification, accreditation of retailers, and regular reassessment is recommended to prevent further deaths.
