Austin McCallum (SN 311) was born in Ballarat and attended the Humffray Street State School. He was a 22 year old farmer when he enlisted on August 17th 1914, along with his brother Clement. They both joined the 8th Battalion which sailed on the Benalla on October 19th. Together they were in action at the April 25th 1915 Gallipoli landing, and close to each other when the 8th Battalion went into action at Krithia on May 8th. Austin was killed in this action just a short distance from Clement who, with a couple of comrades, gave Austin ‘a decent burial'. He is buried in Redoubt Cemetery, Helles, Turkey.

His brother Clement was killed in France in 1918 and is also honoured with a tree in the Avenue.
