Tom Graham was born in Inverness, Scotland, in April 1897. When he enlisted at Seymour on 24 March, 1916, he was eighteen and eleven months old and working as a crockery packer. He have his  address as 36 Berry Street, East Melbourne, and appears to have had no family in Australia. His next of kin was listed as his mother, living at 21 McLean Street, Glasgow. 

He was immediately attached to the Australian Medical Corps at Ascot Vale, then sent to the No. % Australian General Hospital at Royal Park, where he stayed 'on loan' from 28 March to 7 July, when he was diagnosed with V.D. and sent to Langwarrin for treatment. he was released from hospital on 21 October and went back to the No. 5 AGH until 25 October when he was sent to the Clearing Hospital in Seymour. From here, he was attached to the 6th Reinforcements of the 38th Battalion, and embarked from Melbourne on 16 December, on board HMAT Medic.  The Reinforcements were landed at Plymouth on 14 February, 1917, and then marched out to join the 14th Training Battalion at Hurdcott from 3 March-7 April, when they were moved to Durringham Camp and attached to the 10th Training Battalion. Finally, on 22 May, 1917, they left England from Southampton, where Tom Graham was moved from the 38th Battalion to reinforce the 6th Battalion in France.

He was to be wounded twice in the ten months he served on the Western Front. on 9 October, 1917, he was wounded in action, with gunshot wounds to his left hand and right knee. probably at Broodseinde in the Third Battle of Ypres. he was sent back from France to the Lewisham Military Hospital in London, but the wounds wre not serious enough to leave him with any disability and he was released to rehabilitation. On 10 November, he went AWL and went missing until he was picvked up on 23 November. he was charged and given a sentence of 20 days Field Patrol and loss of wages. On 26 February, 1918, he was charged with sleeping in an unauthorised place and on 3-4 March, he was again AWL. 

Tom Graham returned to France from Langridge Deverill on 20 March, rejoining the 6th Battalion on 25 March, 1918. On 3 may, he received a gunshot wound to his right buttock, probably at Villers-Bretonneux. He was invalided out to Britain, only returning to France when the war was over. Again his history is of absenteeism. He went AWL from 16 August to 9 September, 1918, and was given 50 days detention, although 35 days were remitted through intervention by a senior officer. On 9 October, he was again AWL, leaving Sandhill and brin Picked up in London and was given 6 days Field Patrol. On 17 September, 1919, he was again in hospital with VD and spent 45 days at Bulford, where the hospiat specialised in treating veneral disease. He must have been sent back to France to help with the post-war clean-up and was arrested at Rouelles for being drunk, without a pass, and having damaged a window, worth 16 francs.

He returned to Australia on board the Devon on 28 November, 1919, on board the Devon. From here, he disappears. His mother, Catherine Graham, was living by 1922 at Inverne 38, Crane Avenue, Haberfield, Sydney, but it was impossible to trace him. There are too many Tom Grahams of about his age in the Electoral Roll, and a search of the Marriage and Death records proved futile.
