Owen was born in London, England and came to Australia with his family when he was a baby. At the time of his enlistment in August 1914, he had been working as a Labourer in the Inverell District. He had spent a year and a half in the 5th Light Horse and was with one of the early groups of men to leave Inverell for war service.
After serving at Gallipoli and Egypt, he was promoted to Bombardier and sent to France. The following year he was promoted to Acting Corporal. Early in 1918, he was hospitalised in England at Chester War Hospital with bronchitis, eventually returning to his unit in France. Seriously wounded in action during August 1918, he was sent to the casualty clearing station where, at the age of thirty three, he died.
Corporal Owen Fox was buried at St. Sever Cemetery Extension, Rouen, France.
Locally his name is recorded on an Honour Roll at Beaulieu Hall and on the Inverell Honor Roll as well as the Inverell Cenotaph. A memorial Kurrajong tree was planted for him in Kurrajong Parade on the Glen Innes Road.
