Diamond Tree

The Diamond Tree is a giant karri tree located 10 km south of Manjimup, Western Australia on the South Western Highway.
A wooden viewing platform built in 1939 is located 49 metres up, and was the oldest wooden platform fire look-out in use until its closure in 2019.
The Diamond Tree was one of three lookout trees in the Southern Forests and was used as a fire lookout every summer from 1941 to 1973. The tower was used by DEC (Department of Environment & Conservation) to support aerial surveillance from time to time.
Diamond Tree was permanently closed to climbing in 2019 after expert assessments found rot in the base of the tree and recommended all climbing should cease.
