The timber is not often exploited due to the high buttresses and poor form. It is also very hard and difficult to work. The timber is, however, suitable for heavy construction if treated, piles, railway sleepers, heavy duty furniture, fender supports, flooring (heavy traffic), door and window frames and sills, posts, beams, joists, rafters, telegraphic and power transmission posts and cross arms, tool handles (impact), staircase (carriage, newel, riser, stringer, tread, bullnose, round end and winder) and vehicle bodies (framework and floor boards). The dark streaky core is suitable for decorative works, panelling, mouldings, joinery and cabinet making.
