Grayden was educated at state schools and then at Perth Technical College, as part of an apprenticeship commenced in 1938 as a motor mechanic with Winterbottom Motors.[3] He attempted to enlist in the Australian Army when the Second World War broke out in September 1939, but was rejected. He succeeded the following year after lying about his age. Grayden joined the 2/16th Infantry Battalion as a private, but was soon promoted to corporal and then selected to attend Officer Training School in Bonegilla. He served on the Syrian campaign and then in 1942 was sent to New Guinea, where he took part in the Kokoda Track campaign, the Battle of Buna–Gona, and the Markham and Ramu Valley campaign. He ended the war in Borneo and took part in the Battle of Balikpapan.[1]
