Arthur Kodak, an Estonian from Revel (Tallinn) came to Australia in 1910 as a seaman. He had a trade of compositor and worked in Brisbane.
He served with the 26th Battalion on the Western Front as Arthur Kadak. He was severely wounded at Pozières (with gunshot wounds to the head and chest) in August 1916. After recovery in Brisbane he served in the Royal Australian Naval Brigade.
After the war he worked in sugar mills in Queensland, and later settled in Sydney, where he married an Australian woman, Alice Lynch. He worked as a labourer and storeman and had a hard time during the Depression, when he lived in the unemployment camp at La Perouse.
John Bunke, a seaman from Libava (Liepaja) in Latvia, spent 25 years at sea before he landed at Busselton in Western Australia in 1911. He settled at Geraldton, working as a fisherman and living in a fishing boat there.
Enlisting in the AIF in Melborne, he was discharged five months later as medically unfit (he was about 47 years old by that time).
Harry Cooper, a Jewish man from Kovno (Kaunas) in Lithuania, came to Melbourne probably from South Africa, where his father lived. He worked as a commercial traveller in Victoria.
He tried to enlist in the AIF at the beginning of the war, but was rejected. In July 1915, after the second attempt, he was finally accepted and sailed to the front with the 7th Battalion. Later he was transferred to the 3rd Battalion and fought at the Western Front. In January 1918 he was wounded in the head and received a knife wound to the left hand, probably while in direct combat with the enemy.
While convalescing in London, he met a Jewish girl, Lena Heller. They married in January 1919, sailed together to South Africa, and lived in Johannesburg.
