Australia has some of the most durable and beautiful timbers in the world, making them ideal for architecture and design. Timber provides a sense of organic warmth, softness and tactility that few other materials possess and offers positive health benefits, similar to those created by spending time in nature.
Here’s a guide to nine native Australian timbers including their colours, textures, qualities and common applications.
Here’s a guide to nine native Australian timbers including their colours, textures, qualities and common applications.
Hardwood versus softwood
Whether a timber is hardwood or softwood doesn’t refer to its strength, as one might expect, but rather its seed structure. Hardwood trees’ seeds are produced in an enclosed form with some sort of covering, such as a shell or fruit.
Softwood trees form naked seeds that are dropped to the ground. Hardwoods tend to be slower growing than softwoods and are therefore usually more dense, however, this is not always the case.

1. Jarrah
Eucalyptus marginata
Jarrah is a slow-growing tree that hails from the iron- and aluminium-rich plains in the southwest corner of WA. It is one of the few commercial hardwood species from WA and only a limited portion of the jarrah forest may be harvested annually.

Jarrah is a slow-growing tree that hails from the iron- and aluminium-rich plains in the southwest corner of WA. It is one of the few commercial hardwood species from WA and only a limited portion of the jarrah forest may be harvested annually.
Colour: Jarrah timbers reflect the hues of the WA landscape, with rich tones that range from soft salmon pink to rich reddish brown, which can deepen to a soft burgundy over time.
Texture and grain: The grain tends to be interlocked or wavy, with a medium to coarse texture.
Qualities: Jarrah is 15 percent more dense than oak and won’t burn unless exposed to a constant flame.

Applications: Jarrah is a versatile hardwood used for engineering, construction and decorative purposes. It is a popular choice for flooring, joinery, turnery and indoor and outdoor furniture. It is also suitable for heavy construction and exterior cladding.
Jarrah is widely available as a recycled timber salvaged from old houses, bridges, warehouses and other structures, and can be machined and re-milled for a fresh, new appearance. It readily accepts paint, stain or polish.

2. Spotted gum
Corymbia maculata
Spotted gum is the common name for four hardwood species that grow along Australia’s east coast from northeast Victoria to the northern tablelands of Queensland. They may also be found in western areas of southern Queensland. The descriptor ‘spotted’ refers to the soft mottled colour of the wood, which is caused by the weathering of the outer tree as it sheds elliptical strips of bark.

Colour: Its colour can vary from pale grey-browns and soft creams to rich chocolate red-brown.
Texture and grain: It has a wavy grain that produces an attractive rippled effect.
Texture and grain: It has a wavy grain that produces an attractive rippled effect.
Qualities: Spotted gum is a tough timber, which according to expert testing can be used in bushfire-prone areas without having to be subjected to fire-retardant treatment. It has lower tannin content than other Australian hardwoods and is less prone to bleed-through of tannins, and therefore staining.
Applications: Spotted gum is suitable for a range of building applications, such as posts and poles, framing, flooring, lining, decking and cladding. It is also used for indoor and outdoor furniture, turnery, joinery and in the manufacture of veneer and plywood. It can be painted, stained or polished.

3. Blackbutt
Eucalyptus pilularis
Blackbutt is a good plantation timber due to its quick growth and versatility. The hardwood timber is commonly available in NSW and southern Queensland where it’s often used for building framework. The common name blackbutt comes from the tree’s appearance after bushfire when the buttress (or butt) is significantly darker.

Colour: Blackbutt ranges in colour from cream to pale brown, sometimes with a slight tinge of pink.
Texture and grain: It has an even texture and generally a straight grain.
Qualities: Blackbutt provides good fire resistance and can be used in bushfire-prone areas without having to be subjected to fire retardant treatment.

Applications: Blackbutt is commonly used for structural and exterior applications including building framework, flooring, cladding, decking and lining. Inside it’s used for furniture, turnery, flooring, joinery, and here for the kitchen bench. Blackbutt is also used to produce plywood.
Blackbutt can be stained, painted or polished, however, high tannin and extractives content can result in staining of painted surfaces exposed to the weather.

4. Brush box
Lophostemon confertus
Brush box is a medium- to large-sized Australian hardwood tree that grows along the edges of the NSW and Queensland rainforest areas.
Lophostemon confertus
Brush box is a medium- to large-sized Australian hardwood tree that grows along the edges of the NSW and Queensland rainforest areas.
Colour: Brush box has a beautiful rich colour that can vary from pale pinkish grey to rich reddish brown.
Texture and grain: It has a fine and even texture with an often curly interlocking grain.
Texture and grain: It has a fine and even texture with an often curly interlocking grain.
Qualities: Brush box is hardy and its high density makes it resistant to wear and splintering. Its natural waxiness occasionally causes some adhesion problems with some highly solvent floor finishes, but it is a very good base for paints and stains.
Applications: Brush box is used for a variety of applications including flooring, cladding, panelling and some structural applications such as framing and laminated beams. Inside, its interlocking grain is an attractive feature that enhances its appeal for joinery, turnery and flooring.

5. Grey ironbark
Eucalyptus drepanophylla
Grey ironbark is a high-quality premium hardwood that was used by Indigenous Australians to make spear throwers, while its bark was boiled for treating sores. The species is found from northern NSW to Bundaberg, Queensland, and in scattered patches further north.

Colour: Red ironbark timber ranges from deep dark red to red-brown.
Texture and grain: It has a fine and even texture with an interlocked grain.
Texture and grain: It has a fine and even texture with an interlocked grain.
Qualities: One of the hardest timber species commercially available worldwide, red ironbark is extremely hardwearing and highly durable. It is another timber that can be used in bushfire-prone areas without having to be subjected to fire-retardant treatment.
Applications: Red ironbark is used for exterior structural uses due to its long-term performance in weather-exposed applications. However, because of the timber’s density and interlocking grain it can be difficult to work with, which limits some applications that require fine detailing. The timber is also suitable for framing, flooring, decking and cladding.

8. Victorian ash
Eucalyptus delegatensis, E. regnans
Victorian ash comes from two of the same eucalypt species as Tasmanian oak and the hardwoods are often interchangeable. Victorian ash is grown as a plantation timber due to its quick growth and resistance to insect attack.

Qualities: The natural resins in cypress pine are aromatic and are believed to contribute to the timber’s natural durability.
Applications: Cypress pine is used for general building construction in areas where the species naturally occurs. It is more widely used for furniture, joinery, flooring, lining and cladding and its distinctive tight knots enhance its decorative appeal for exposed faces.
