- Dressed seasoned flooring, lining, mouldings and joinery.
- Office fixtures.
- Picture frames.
- Light boat building.
- Brush stock.
- Broom handles.
- Density: 625kg/m3 at 12% moisture content; about 1.6m3 of seasoned sawn timber per tonne.
- Strength groups: S5 unseasoned, SD6 seasoned.
- Stress grades: F5, F7, F8, F11, (unseasoned) F7, F8, F11, F14 (seasoned) when visually stress-graded according to AS 2082—2000: Timber—Hardwood—Visually stress-graded for structural purposes.
- Joint groups: JD3 seasoned.
- Shrinkage to 12% MC: 5.0% (tangential), 2.5% (radial).
- Unit shrinkage: not available.
- Durability above-ground: Class 4 (life expectancy less than 7 years).
- Durability in-ground: Class 4 (life expectancy less than 5 years).
- Lyctine susceptibility: untreated sapwood susceptible to lyctine borer attack.
- Termite resistance: resistant.
- Preservation: sapwood easily impregnates with preservatives but penetration of heartwood is negligible using available commercial processes.
- Seasoning: dries satisfactorily using conventional air and kiln seasoning methods.

- Growth rings: absent.
- Vessels: numerous, very small, indistinct without a lens, solitary and in radial groups of less than 4; without tyloses and deposits.
- Parenchyma (soft tissue): not visible under a lens.
- Rays: 2 kinds—large (visible without a lens) and fine (difficult to see even with a hand lens).
