Blackbutt is an iconic Australian hardwood species, grown along the eastern coast from southern Queensland into New South Wales. Its botanical name is Eucalyptus pilularis, and it has earned a strong reputation for structural strength, weather-resistance and aesthetic appeal. With a heart-wood that ranges from golden yellow to pale brown (occasionally with a pinkish hue) and a generally straight, even grain, it offers a premium appearance while delivering high performance.
Outstanding durability & longevity
It is rated as Durability Class 1 for above-ground use (life expectancy over 40 years) and offers strong fire resistance (suitable for bush-fire zones) and natural termite resistance, making it a go-to choice for challenging exterior and structural applications.
Natural fire & termite resistance
Because of its density, structure and extractives, Blackbutt is one of the preferred hardwoods in bushfire-prone zones (BAL-rated) and has inherent resistance to lyctid borer and termite attack.
Warm aesthetic & structural versatility
With a uniform straight grain, golden to pale brown colour and excellent machineability, Blackbutt works beautifully for visible structural elements, cladding, outdoor joinery and more, providing both form and function.
