Vernacular Names

Northern wattle, red wattle (En).


South-western Papua New Guinea and Australia (coastal Queensland); also planted in plantations in Kalimantan.


The wood is used as wattle, e.g. for heavy construction, furniture, flooring, cabinet-making, boat building, panelling, hardboard and veneer. It has long been used for native building posts and has a reputation of being durable.


A medium-sized tree up to 25(—33) m tall, bole branchless for up to 13(—18) m, up to 50 cm in diameter, fluted or spurred at base, bark surface rough, deeply fissured, grey to grey-brown, inner bark reddish, branchlets angular; phyllodes falcate, 11—20 cm 1—4.5 cm, 2.5—12 times as long as wide, with 3—5 yellowish main longitudinal veins and a yellowish margin, secondary veins not anastomosing; flowers in spikes, 5-merous, corolla 1.3—1.6 mm long; pod flat, up to 5 cm 2—3.5 cm, woody, with transverse but hardly reticulate venation. Acacia crassicarpa has often been confused with Acacia aulacocarpa. It is found in savanna sometimes with Banksia spp., in woodland or burnt-over open forest, on flats dominated by Melaleuca and Tristania spp., at 10—30 m altitude in Papua New Guinea, up to 700 m in Australia. The density of the wood is 670—710 kg/m3 at 12% moisture content. See also the table on wood properties.
