Lt. Carl McGibbon Jess (reported missing) is the elder son of Lt Gen Sir Carl Jess and Lady Jess of Toorak. Aged 20 he was born in Surrey, England and was educated at Hale School, Perth and MGS. He was in the school cadet corps, and later joined Royal Melbourne Regiment, gaining his commission before he joined the AIF in July 1940. Since going overseas Lt. Jess was in the AIF garrison at Tobruk. Recent reports from Tobruk gave details of several successful AIF patrols, one of which, led by Lt. Jess, brought back a number of enemy prisoners. He was employed on the staff of an advertising firm before enlisting. Lt. Jess announced his engagement early in April 1941 to Miss Betty Wallace Mitchell, younger daughter of Mr. and Mrs. Wallace Mitchell of Melbourne.
