Ivo Reginald Parker (SN 9) born at Ballarat, was a 21 year old iron turner when he enlisted in Ballarat on August 17th 1914. With the 8th Infantry Battalion, he embarked from Melbourne on October 19th aboard the Benalla and sailed to Egypt before landing at Gallipoli on April 25th 1915. He was evacuated to hospital in Egypt in late August with an abdominal problem. Whether this was due to illness or a shrapnel wound is not clear in his service record. He was assessed as unfit for further active service and was returned to Australia aboard the Seeang Choon. He disembarked at Melbourne on August 18th 1916 and was discharged medically unfit on November 7th.

His brother Francis also served in the AIF and is honoured with a tree in the Avenue.
