Timber
Dark red with moderately fine texture and interlocked grain. Very hard, strong, and extremely durable. Density about 1150 kg/m3. Used for heavy engineering construction, railway sleepers and in turnery. Gaining popularity as furniture timber and for electric fence posts and droppers. Posts last in the ground for over 100 years. Appears to retain rich-coloured timber when grown quickly. Potential for woodlot planting for farm timber, firewood and valuable specialty timber.
Wildlife
Excellent habitat. Honeyeaters, Swift Parrots, lorikeets, Squirrel Gliders and Sugar Gliders attracted to nectar, an important winter food source. Important food source for many native insect-eating birds and mammals. Hollows good nest sites for many birds and mammals.
