Kauri, Queensland

Queensland kauri pine is one of Australia's native softwood timber species. Its species name, Agathis robusta, is derived from its cones, which look like a ball of thread (agathis), combined with its vigorous growth (robusta). An attractive timber suited to many indoor uses, including fine cabinetry, the Queensland kauri was heavily logged in the early years of European settlement. Large trees are therefore more rare now than in pre-European times; despite this, the species is not classified as endangered.

Queensland kauri occurs in two localities: in southern Queensland on Fraser Island and around Maryborough; and there is a northern population on the Atherton Tableland west of Cairns. Although these two populations were once given different scientific names (A. robusta in the south and A. spathulata in the north), they have since been discovered to be the same species. Queensland kauri is a large, coniferous tree with a straight trunk, growing to a height of 25-40 metres with a trunk diameter of between 100 - 200cm. The trunk is clear of branches for over half its length. The characteristically straight and symmetrical trees are covered with smooth to flaky grey-brown bark. Woody scales from collapsing cones gather at the base of these trees.

The timber yielded by this species has a fine even texture that is pale cream to light or pinkish brown in hue, with a straight grain. Queensland kauri withstands some exposure. It dries quickly with little degrade but needs protection against blue stain, microscopic fungi that commonly infest the sapwood of trees.

Queensland kauri timber is commonly used for cabinetwork, turning, joinery and shelving. It is suitable for use in pattern making, lining, flooring, vats, boxes, battery separators and plywood. It is otherwise used for making furniture and violin bellies.
