Don Tate volunteered for the army, volunteered for the infantry, and volunteered to go to Vietnam just prior to Christmas, 1968. He served as a reinforcement to three units — the 4th Battalion; the 2nd D&E Platoon; and the 9th Battalion.
He was wounded in action on the 19th July, 1969, when running to the assistance of fallen members of the first section of his platoon. He was subsequently hospitalised for more than two years.
Don's memoir, The War Within was published by Murdoch Books in 2008 and became a best-seller.
In 2000, he received the Australian Sports Medal for services to sport.
