Quick answer
Choose spotted gum if you want maximum hardness, a strong Australian look with varied colour and wavy grain, and long straight boards. Choose European oak if you want a calm, even, lighter floor, finish flexibility (natural, white, smoked, stained), or a herringbone or chevron pattern. Spotted gum wins on hardness; oak wins on design versatility and pattern formats.
Spotted gum (Corymbia species) is a hardwood from eastern Australia, known for its colour range from pale grey-brown to deep reddish brown and its wavy "fiddleback" figure. European oak (Quercus robur and Q. petraea) is a temperate hardwood from Europe, with a honey-to-straw colour and a straight, even grain.
European oak vs spotted gum at a glance
| European oak | Spotted gum | |
|---|---|---|
| Origin | Europe (France, Germany, Central and Eastern Europe) | Eastern Australia (NSW, QLD) |
| Janka hardness | about 4.2–6.1 kN | about 11 kN |
| Colour | Honey, straw, light brown; even | Grey-brown to reddish brown; varied |
| Grain | Straight, calm, visible rays | Wavy, often fiddleback, gum veins |
| Finish options | Natural, white-wash, smoked, stained, oiled | Mostly natural clear finishes |
| Grading | European grades (e.g. Prime) | AS 2796 (Select, Standard, High Feature) |
| Common formats | Wide boards, herringbone, chevron | Straight boards (strip, overlay) |
| Supply cost | Raw solid oak herringbone about $94.99/m² incl. GST | About $55–$130/m² incl. GST |
Look
The biggest difference is visual. Spotted gum is lively – colour shifts board to board, and the wavy grain gives a strong natural character that many Australians love. European oak is quieter. A Prime grade oak floor has a calm, consistent tone that suits Scandinavian, Japandi, Parisian and contemporary interiors, and it takes stains and smoked or white finishes evenly. Spotted gum's natural colour is usually the feature, so it is rarely stained. See oak flooring trends.
Hardness and durability
Spotted gum is roughly twice as hard as European oak: about 11 kN on the Janka scale against 4.2–6.1 kN (PFC, Flooring Expert). That's a real advantage in homes with large dogs, stiletto heels or heavy furniture – dents are less likely. Oak relies more on its finish, and minor marks blend into the grain. Hardness also cuts the other way: very hard species are harder work to sand. Read what Janka means and its limits and timber floors and pets.
Stability
Both species move with humidity; the format and installation make the bigger difference. All solid timber gains and loses moisture – Australian interiors typically sit at 8–14% equilibrium moisture content, and flooring should be installed within about ±2% of its in-service level (WoodSolutions). Australian-made boards are commonly supplied at 10–12% moisture content (ATFA). Imported oak must be acclimatised to local conditions – see acclimatising oak flooring. Oak parquet's short blocks, laid in two directions, spread movement across many joints.
Cost
Supply prices overlap; installation format drives the total.
| Item | Typical range (incl. GST) | Source |
|---|---|---|
| Solid Australian hardwood (spotted gum, blackbutt), supply | $55–$130/m² | D&G, HH Timber |
| Solid Australian hardwood, installed | $120–$367/m² by city | HH Timber |
| Raw solid French oak herringbone, supply | $94.99/m² retail | SET Timber Supplies |
| Herringbone labour only | $60–$100/m²; $90–$120+/m² complex | The Flooring Guys |
| Sanding and coating | $30–$70/m² | WhatsTheDamage |
A straight-laid spotted gum floor will usually cost less to install than oak herringbone, because pattern work takes more labour. Compare like with like: straight spotted gum against straight oak boards, or spotted gum parquet against oak parquet.
Installation
Spotted gum strip floors are commonly nailed to joists or battens, or glued to slab or ply. European oak parquet is glued to a flat, dry slab or plywood substrate. For slabs, flatness within about 3mm over 3m and a moisture barrier or moisture-barrier adhesive are typical requirements (Bowens). Raised timber floors in bushfire-prone areas may have extra requirements under AS 3959; internal floors on slab generally aren't affected (WoodSolutions).
Maintenance
Care routines are the same. Sweep, damp-mop with a timber-safe cleaner, use felt pads, and recoat before the finish wears through. Oak's softer surface means mats at entries and chair pads are worth the effort.
Sustainability and provenance
Spotted gum wins on food miles; oak needs good import paperwork. Spotted gum comes from Australian native forests and plantations, so its supply chain is short. European oak travels further, and importers must run a due-diligence system under the Illegal Logging Prohibition Act (DAFF); from 30 December 2026 the EU Deforestation Regulation also applies to EU timber operators (Council of the EU). For either species, ask for FSC or PEFC certificates where certification matters.
Suitability by room and climate
| Situation | Better fit |
|---|---|
| Family home with big dogs and heavy use | Spotted gum |
| Herringbone or chevron feature floor | European oak |
| Light, Scandinavian or Japandi interior | European oak |
| Warm, Australian-character interior | Spotted gum |
| Smoked, grey or stained finish | European oak |
| Apartment or slab with pattern floor | European oak parquet (glued) |

Frequently asked questions
Is spotted gum harder than oak?
Yes. Spotted gum rates about 11 kN on the Janka scale, against about 4.2–6.1 kN for European oak, so it resists dents from heels, furniture and dropped objects much better. Oak relies more on its finish for wear resistance.
Which is more expensive, spotted gum or European oak?
They overlap. Solid Australian hardwood supply is commonly about $55–$130/m², and raw solid oak herringbone sits around $94.99/m² at retail. Format matters more than species – parquet costs more to install than straight boards.
Can spotted gum be laid in herringbone?
It can be milled into parquet, but herringbone and chevron in Australia are far more commonly made from European oak, which has calmer colour, an even grain and wide availability in parquet formats.
Does spotted gum or oak suit a coastal or humid home better?
Either works indoors when the timber is acclimatised to local conditions. The installation and moisture checks matter more than the species.
Can European oak be made to look like spotted gum?
Not really. Oak can be stained darker or smoked, but it won't reproduce spotted gum's colour range and wavy grain. If that look is the goal, choose spotted gum.
