Blackbutt timber boasts an even texture with a generally straight grain, although it can sometimes be interlocked. This straight grain makes it particularly appealing for interior applications like flooring and joinery. The heartwood varies from golden yellow to pale brown and may occasionally have a slight pinkish hue. The sapwood is much paler and can be difficult to distinguish from the heartwood. Small gum veins may also be present, adding to its character.

Common Applications

Blackbutt is a versatile and popular timber used for both structural and aesthetic purposes. In New South Wales and southern Queensland, it is frequently utilized for timber framing. Other common applications include:

  • Cladding
  • Internal and external flooring
  • Decking
  • Joinery
  • Landscaping
  • Furniture
  • Plywood manufacturing


Drying Blackbutt requires careful attention to avoid surface checking on the tangential surface. It should not be re-conditioned as this may exacerbate surface checks. Blackbutt can be stained, painted, or polished, although its tendency to surface check can pose challenges for painting. The high extractive content in mature wood can cause issues with some adhesives and may result in staining on painted surfaces when exposed to weather. However, young regrowth wood presents fewer problems. Blackbutt machines well but is only fair for steam bending.

Origin and Availability

Blackbutt grows in the coastal regions of New South Wales and Queensland, from Bega in NSW to Maryborough in Queensland. It is generally readily available in these areas. Suppliers can provide information on availability in other parts of Australia.
