According to the pathologist, Sir John Burton Cleland, emeritus professor at the University of Adelaide, the man was of "Britisher" appearance and thought to be aged about 40–45; he was in top physical condition. He was 180 centimetres (5 ft 11 in) tall, with hazel eyes, fair to ginger-coloured hair, slightly grey around the temples, with broad shoulders and a narrow waist, hands and nails that showed no signs of manual labour, big and little toes that met in a wedge shape, like those of a dancer or someone who wore boots with pointed toes; and pronounced high calf muscles like those of a ballet dancer.

Clean-shaven and with no distinguishing marks, the man carried no identification, which led police to believe he had committed suicide. His teeth did not match the dental records of any known person in Australia.
An autopsy was conducted, and the pathologist estimated the time of death at around 2 a.m. on 1 December.
