In 2016, the Diamond Tree celebrated its 75th birthday. Roger Underwood, an ex Forester-In-Charge in the Karri Forest area, has written a booklet called:
Diamond Tree - Celebrating a masterpiece of bush engineering. It details the construction of tree towers and also covers the extensive renovation of the Dimond tree tower in the early 90's. A very intersting read and for information about the booklet, please contact Roger via his email address

The Diamond Tree, with it's 130 pegs, was closed for climbing by the public in mid 2019 due to safety concerns. Ultrasounds by an arborist showed that the internal hardwood was affected by fungus, which takes it from solid hardwood to being softer and less structually sound.
