This morning a single vehicle accident occurred on Canberra Avenue outside HMAS Harman. A truck impacted a tree, resulting in the single male occupant of the truck becoming trapped. ACT Ambulance Service Paramedics, working in collaboration with NSW Paramedics, stabilised the patient on scene while NSW fire fighters used hydraulic equipment to free the mans legs. ACT Paramedics then transported the patient to The Canberra Hospital in a stable condition. Motorists are advised that Canberra Avenue remains open, although recovery of the truck is expected to cause delays in the late morning.
