AI-generated summary
Christina Maree Chamberlain, aged 60, died when her vehicle drifted across lanes and collided with a tree on Great Alpine Road. She was taking multiple medications including oxycodone, amitriptyline, sertraline, diazepam, and carbamazepine—many capable of causing drowsiness. She had significant comorbidities including hypertension, cardiomegaly, sleep apnoea, and chronic back pain. While the coroner could not definitively establish whether medications or a medical episode caused the incident, the lack of evasive action (braking or steering) was consistent with the driver being asleep, unconscious, or experiencing a medical event. No mechanical failure was identified. The coroner noted concern about three similar tree-strike incidents on the same road stretch in three years and recommended safety barrier installation.
