The War Memorial Oak tree was planted on 29 August 1914 about 25 metres from War Memorial Drive. By 2014 the tree had a canopy approximately 30 metres in diameter, and a life expectancy of 500 years. The tree, and a plaque immediately adjacent to the base of the tree (c.1917), are both heritage listed. The plaque states: "The War Memorial Oak planted by His Excellency the Governor Sir
Henry Galway on Wattle Day August 29th 1914."
