Australian Timber Species Guide

Everything you need to know about the most common hardwood floor species in Newcastle and the Hunter Valley.

Newcastle and Hunter Valley homes feature a wide range of Australian hardwood species. Each has different characteristics, responds differently to sanding, and looks best with specific finishes. Russell has worked with all of these species extensively over 20+ years and recommends Bona finishing products for all of them.

Spotted Gum

Spotted Gum

Corymbia maculata
Janka Hardness: 11.0 kN
Colour
Brown to chocolate with grey tones
Grain
Wavy, interlocked with fiddleback figure
Durability
Class 2 (above ground)

One of the most popular flooring species in the Newcastle region. Spotted gum has stunning grain patterns with a wavy, fiddleback figure that catches the light beautifully. It sands well and takes finishes evenly. The colour varies from light browns through to deep chocolate tones, often with grey undertones.

Best for: Living areas, hallways, bedrooms. Extremely versatile and suits both modern and traditional homes.

Bona recommendation: Bona Traffic HD in satin for high-traffic areas, or Bona Mega ONE satin for standard residential use. The satin sheen highlights the natural grain variation beautifully.
Blackbutt

Blackbutt

Eucalyptus pilularis
Janka Hardness: 9.1 kN
Colour
Pale honey to light brown
Grain
Even, straight with occasional wave
Durability
Class 2 (above ground)

Blackbutt is the most widely used hardwood flooring species in NSW. It has a consistent, even colour in pale honey tones that brighten rooms and create an open feel. It sands easily and is very forgiving, making it a favourite among floor sanders. The even grain means few surprises during the sanding process.

Best for: Open-plan living, kitchens, modern homes. Its light colour makes spaces feel larger and pairs well with contemporary interiors.

Bona recommendation: Bona Mega ONE in matt or satin. The matt finish gives blackbutt a natural, Scandinavian look that is very popular in modern Newcastle homes.
Tallowwood

Tallowwood

Eucalyptus microcorys
Janka Hardness: 8.6 kN
Colour
Olive-yellow to golden brown
Grain
Slightly interlocked, greasy texture
Durability
Class 1 (in ground)

Tallowwood is named for its naturally greasy or waxy feel, which comes from a high oil content. This makes it exceptionally durable and naturally resistant to termites and rot. It is commonly found in older Hunter Valley homesteads and heritage homes throughout the Maitland area. The oily nature requires careful preparation before coating.

Best for: High-traffic areas, heritage restorations, decking. Its natural oils provide excellent weather resistance.

Bona recommendation: Requires thorough sanding to remove surface oils before coating. Bona Mega ONE in satin adheres well once properly prepared. Russell recommends an extra preparation pass for tallowwood floors.
Brush Box

Brush Box

Lophostemon confertus
Janka Hardness: 9.5 kN
Colour
Pink-brown to reddish brown
Grain
Interlocked, even texture
Durability
Class 2 (above ground)

Brush box has a distinctive pinkish-brown colour with an interlocked grain that gives it a unique character. It is extremely hard-wearing and was historically used in heavy-duty applications like wharf decking and gymnasium floors. In residential settings, it brings warmth and richness. Common in mid-century Newcastle homes.

Best for: High-traffic areas, stairs, commercial spaces. Exceptionally durable and handles heavy foot traffic without showing wear quickly.

Bona recommendation: Bona Traffic HD for maximum durability. The interlocked grain sands best with sharp abrasives and a methodical approach to avoid chatter marks.
Ironbark

Ironbark

Eucalyptus spp.
Janka Hardness: 14.0 kN
Colour
Deep red to dark chocolate brown
Grain
Interlocked, fine and even
Durability
Class 1 (in ground)

Ironbark is one of the hardest timber species in Australia. Its density makes it extremely durable and resistant to wear, but it also means it requires more effort to sand. Russell uses professional-grade Bona sanding equipment that handles ironbark's hardness without issue. The deep red-brown tones create a dramatic, luxurious floor. Popular for decking in coastal areas like Nelson Bay.

Best for: Decking, outdoor areas, high-wear commercial spaces. Its extreme hardness and natural durability make it virtually indestructible in most residential settings.

Bona recommendation: For interior ironbark, Bona Traffic HD in satin. For exterior decks, Bona Decking Oil which penetrates the dense timber and provides UV protection.
Jarrah

Jarrah

Eucalyptus marginata
Janka Hardness: 8.5 kN
Colour
Rich reddish-brown, darkens with age
Grain
Even, slightly interlocked
Durability
Class 2 (above ground)

Though native to Western Australia, jarrah is found in many Newcastle homes, particularly in renovations and as imported recycled timber. Its signature deep red colour is instantly recognisable and only deepens with age. Jarrah sands well and takes finishes evenly, producing a rich, warm result that is hard to match with any other species.

Best for: Feature rooms, dining areas, heritage-style renovations. Its rich red tones create a statement floor that anchors a room.

Bona recommendation: Bona Mega ONE in satin or gloss. A gloss finish on jarrah creates a truly premium look, enhancing the depth of the red tones.
Tasmanian Oak

Tasmanian Oak

Eucalyptus delegatensis / E. obliqua / E. regnans
Janka Hardness: 5.5 kN
Colour
Straw to reddish brown
Grain
Straight, even with occasional gum veins
Durability
Class 3 (above ground)

Tasmanian oak is actually a collective name for three eucalyptus species from Tasmania and Victoria. It is softer than most other hardwoods on this list, which makes it easier to sand but more susceptible to dents and scratches. Its light colour and even grain make it popular for staining, as it takes colour beautifully and evenly. Very common in newer Newcastle builds and renovations.

Best for: Bedrooms, living areas in low-traffic homes, stained floors. Excellent for achieving custom colour effects with Bona stains.

Bona recommendation: Bona Traffic HD is strongly recommended due to the softer timber, as it provides maximum scratch and wear resistance. Bona stains can be applied to achieve virtually any colour from blonde to walnut.
Cypress Pine

Cypress Pine

Callitris glaucophylla
Janka Hardness: 6.5 kN
Colour
Honey gold with distinctive dark knots
Grain
Straight with prominent, tight knots
Durability
Class 1 (in ground, termite resistant)

Cypress pine is unique among Australian flooring timbers for its natural termite resistance, making it a popular choice in areas with termite risk. The honey-gold colour with distinctive dark knots gives it a character-rich, rustic appearance. It is softer than most hardwoods, so care is needed during sanding. Common in older homes throughout the Hunter Valley, particularly in rural areas around Cessnock and Maitland.

Best for: Homes in termite-prone areas, country-style interiors, heritage renovations. The natural knot patterns create a warm, characterful floor.

Bona recommendation: Bona Mega ONE in satin preserves the natural honey colour and enhances the knot patterns. Avoid heavy staining as it can obscure the unique natural character.

Not sure which species you have?

Identifying timber species can be tricky, especially in older homes where boards have darkened with age.
