He served at Gallipoli until pyrexia forced his evacuation to hospital at Mudros in mid-December, just a week before the general evacuation was completed. In January 1916 he returned to Alexandria in Egypt and served there until November 1917 when he was hospitalised by a lengthy bout of gastritis. He departed from Suez on July 12th to return to Australia on the Port Darwin.
