Wongai is a common fast-growing wattle that is the dominant species on the Dampier Peninsula and can form dense thickets. It is a very hardy tree and its range extends from the Kimberley, Pilbara and north eastern Goldfields regions, including much of the Great Sandy Desert. It also extends into the Victoria River district of the Northern Territory. It grows well in sandplain areas in red sandy or pindan soils over sandstone.They often form dense thickets with spinifex.
Wongai grow to a height of 5 to 15 metres with a well developed canopy. When it flowers in the dry season, the air is heavily scented with a sweet perfume. The bright yellow pollen, can cause hay fever. It has hard grey glossy bark that is occasionally fissured, and when young, its trunk is used ot make spears and boomerangs. Other traditional uses include making string from the bark and using the gum exudate as a food source.
