Brush Box
Scientific name: Lophostemon confertus
Overview
Brush Box is a dense and durable Australian hardwood commonly used in structural, flooring, and exterior applications. Native to eastern Australia, it is known for its medium brown coloration and strong mechanical properties.
While less visually dramatic than species like Jarrah or River Red Gum, Brush Box is valued for its stability, wear resistance, and reliability in heavy-use environments. It occupies a practical, performance-driven niche within the Australian hardwood spectrum.

Quick Facts
- Common Name: Brush Box
- Scientific Name: Lophostemon confertus
- Region: Oceania & Pacific Hardwoods (Eastern Australia)
- Tree Size: 80–120 ft tall, 2–4 ft trunk diameter
- Average Dried Weight: 59 lbs/ft³ (950 kg/m³)
- Janka Hardness: 2,130 lbf
- Color: Reddish brown to pinkish brown
- Grain: Typically interlocked
- Texture: Fine to medium
Identification Characteristics
Brush Box is identified by its relatively uniform medium-brown coloration and straight to slightly interlocked grain. The texture is medium and generally even.
Compared to red-toned Australian hardwoods like Jarrah, Brush Box appears more neutral brown with less dramatic figure. It has a solid, structural appearance and moderate natural luster.
Key identification traits include:
- Neutral medium-brown tone
- Straight or slightly interlocked grain
- Medium texture
- Heavy weight
- Structural character
Working Properties
Brush Box is dense and moderately difficult to machine.
- Carbide tooling recommended
- Moderate tool wear
- Pre-drilling required for fasteners
- Sands to a smooth surface
- Glues well when surfaces are properly prepared
Because of its strength and durability, it is often selected for flooring and structural applications.
Safety Note
Wood dust may cause irritation in sensitive individuals. Standard respiratory protection is recommended during machining.
Common Uses
Brush Box common uses including:
- Hardwood flooring
- Structural beams
- Exterior decking
- Heavy-use interior applications
- Stair treads
- Industrial flooring
Sustainability & Notes
Brush Box is harvested under Australian forestry regulations and is available from managed sources. It remains a reliable commercial hardwood within the Australian market.

Collector Notes
Brush Box is collected primarily as a structural reference species rather than for decorative figure. Its neutral brown tone distinguishes it from the red-heavy Australian hardwoods. Clean, flat-sawn samples best demonstrate its grain structure and density. Because of its weight, thinner labeled sample blocks are recommended for organized collections.
