When Bertie enlisted at Inverell in June 1916 he was a twenty year old Carrier. He joined the 34th Battalion, 4th Reinforcement and departed from Australia on HMAT A30 Border in October.

Sydney had tried to enlist in 1916 but was rejected at Armidale. When he enlisted again at Inverell in August 1917, Sydney stated he was twenty one and that he had spent 6 weeks with the 13th Infantry Battalion. His father gave permission for him to serve overseas. Sydney joined the 1st Pioneer Battalion, 13th Reinforcement.

He was sent to France in April 1918 and invalided back to England in June for admission to Northampton War Hospital. Sydney returned home in 1919 and was medically discharged. The Tingha Advocate newspaper, 9 May 1919, reported he was one of several men given a ‘Welcome Home’ at Gilgai and ‘presented with a set of military brushes’.
