Bunya Pine
Scientific name: Araucaria bidwillii
Overview
Bunya Pine (Araucaria bidwillii) is a monumental Australian conifer native mainly to southeastern Queensland, with smaller natural populations farther north. It is famous for its enormous seed cones and edible nuts, which have profound cultural importance for Aboriginal peoples. Its pale, fine-textured timber was historically used for furniture, joinery, plywood, boxes, and musical instruments.
Quick Facts
- Common Name: Bunya Pine
- Alternate Common Name(s): Bunya-Bunya, Bunya Bunya Pine, False Monkey Puzzle Tree
- Scientific Name: Araucaria bidwillii
- Region: Oceania & Pacific Woods
- Tree Size: Typically 100–150 ft (30–45 m) tall, occasionally taller, with a massive straight trunk
- Average Dried Weight: Approximately 34 lb/ft³ (545 kg/m³)
- Janka Hardness: Approximately 740 lbf (3,300 N)
- Grain: Usually straight, sometimes with mild figure
- Texture: Fine and even
Identification Characteristics
Bunya Pine develops a massive straight trunk and a broad, dome-shaped crown carried on strong horizontal branches. Mature trees have thick, rough dark bark and dense clusters of stiff, sharply pointed leaves. The huge female cones can weigh several kilograms and contain large edible seeds.
Key identification traits include:
- Very tall evergreen conifer with a massive straight bole
- Broad, symmetrical domed crown with heavy horizontal branches
- Thick rough bark, dark brown to nearly black on old trees
- Stiff, glossy, sharply pointed leaves densely arranged on branchlets
- Enormous rounded cones containing large edible nuts
- Pale cream timber with fine even texture and generally straight grain
Working Properties
Bunya Pine is generally easy to saw, machine, turn, glue, and finish. Its fine, uniform texture allows clean mouldings and smooth painted or clear-finished surfaces. Resin pockets, knots, and localized grain deviation may occur, and fasteners near board ends should be pre-drilled when splitting is a concern.
- Machines and sands readily with sharp, well-maintained cutters.
- Usually planes cleanly because the grain is predominantly straight.
- Glues, nails, and screws satisfactorily under normal shop practice.
- Accepts paint, stain, and clear finishes evenly after careful preparation.
- Use properly dried stock for stable joinery and dimensionally accurate components.
Safety Note
Avoid breathing Bunya Pine dust during sawing, routing, turning, or sanding. Use effective dust extraction, suitable respiratory and eye protection, and wash exposed skin after handling. As with other softwoods, individual sensitivity to dust or resin can vary.
Common Uses
Bunya Pine is light to moderate in weight, easy to machine, and valued for its pale color and fine texture. Clear stock is especially suited to interior joinery, furniture, carving, and soundboards.
- Furniture, cabinetry, shelving, and interior joinery
- Plywood, veneers, and laminated components
- Interior lining, mouldings, doors, and joinery
- Doors, windows, and general millwork
- Turnery, carving, toys, and pattern making
- Acoustic-guitar soundboards and other musical-instrument components
Sustainability & Notes
Bunya Pine is assessed as Endangered on the IUCN Red List and has a naturally fragmented distribution. Its cones and edible nuts are culturally significant to Aboriginal peoples, especially the traditional gatherings associated with the Bunya Mountains. Timber should come from documented plantation, salvage, or otherwise legal and responsible sources; old native trees should be protected.
Comparative Notes & Related Species
- Norfolk Island Pine – A close relative in the genus Araucaria, with similarly pale timber but a distinctive symmetrical landscape form.
- Australian Cypress Pine – A durable Australian conifer whose stronger odor, darker color, and natural decay resistance contrast with Bunya Pine.
- Caribbean Pine – A plantation softwood useful for comparing resin content, grain character, and structural applications.
- Radiata Pine – A widely planted construction softwood that is generally coarser and more visibly ringed than fine-textured Bunya Pine.

Collector Notes
Sugar Gum is a valuable reference sample for collectors because its pale color and exceptional density challenge the assumption that very heavy Australian eucalypts are always dark red. A documented specimen should include face grain and end grain, geographic origin, tree age if known, and whether the material came from a plantation, farm shelterbelt, salvage source, or the restricted native range.
