Melbourne, where he became a motor mechanic. He worked in several garages before commencing a part-time course in fitting and turning at the Working Men's College of Melbourne. His college studies were curtailed by the outbreak of World War I, by which time he had accumulated three years part-time military service, firstly in cadets and later in a militia unit, the 29th Light Horse Regiment. World War I In May 1915 Jones joined the Australian Imperial Force, embarking for Egypt in August with the 9th Light Horse Regiment. He landed at Gallipoli the following month and served there until the end of the campaign in December. His experiences at Gallipoli, especially witnessing the death by enemy fire of one of his friends, affected him deeply and he suffered from headaches and nightmares for years afterwards. After briefly transferring to the Imperial Camel Corps, Jones applied to join the Australian Flying Corps (AFC) in October 1916, taking a drop in rank from corporal to private to do so.

He gained his wings on 22 November 1917 and was posted to No. 4 Squadron AFC (also known as No. 71 Squadron RFC) as a second lieutenant in January the following year. Flying Sopwith Camels and Snipes on the Western Front, Jones finished the war a captain and an ace, with seven aerial victories from 150 patrols. He was badly injured by a bullet wound and petrol burns in combat with a German fighter in March 1918, and did not return to his unit for three months. On 29 October 1918 he achieved two kills in one engagement, at Tournai, in what is frequently described as "one of the greatest air battles of the war". Amid a confrontation involving over 75 Allied and German fighters, Jones led his patrol of three Snipes in a dive on ten Fokkers, destroying a brace of enemy aircraft in the attack.
