Norman McMillan Cox (SN 4781) was born in Queensland but was working as a farm labourer in Ballarat when he enlisted there on April 10th 1917. With his father already serving overseas, the 18 year old enlisted with the permission of his mother and embarked from Melbourne with the 29th Battalion in June, on board the Suevic. After training in England, he was posted to France with the 14th Battalion in February 1918. In May he was evacuated to England after being gassed and remained there until the end of the war. He left for Australia on board the Demosthenes in January 1919 and was discharged from the AIF soon after his arrival in Melbourne on March 25th 1919.

His father, John, and his brothers Clarence and Ernest also served in the AIF and all are honoured with trees in the Avenue.
