Native to Australia. The species is commonly riparian, i.e. ringing perennial rivers and semi-perennial creeks, and tends to form discontinuous populations along drainage systems. It is found most commonly on clay soils, it exhibits the ability to grow in a wide variety of soils including calcareous sands and black cracking clays, poor-fertility soils, seasonally waterlogged soils, sandy loams and coral rag.  A. auriculiformis occurs from near sea level to 400 m, but is most common at elevation less than 80 m. It is predominantly found in the seasonally dry tropical lowlands in the humid and sub-humid zones.

An evergreen tree growing to 25 m (82ft) by 5 m (16ft).

BARK: rough hard bark grayish green in color and it is vertically fissured.

LEAVES: Sickle shaped shiny dark green leaves 10-20cm long taper to a blunt tip and are 1.5 – 3.5 cm wide.

FLOWERS: dull golden/yellow rods occurring in pairs

FRUIT: distinctive ear-like pods, woody twisted and hard.

Medicine: Root, bark. http://tropical.theferns.info/viewtropical.php id=Acacia+auriculiformis

Agroforestry: suitable for stabilizing eroded lands, has the ability to fix atmospheric nitrogen and tolerance of both highly acidic and alkaline soils make it popular for stabilizing and re-vegetating mine spoils, improves soil physio-chemical properties such as water-holding capacity, organic carbon, nitrogen and potassium through litter fall, its phyllodes provide a good, long-lasting mulch, makes an excellent shade tree.

The bark contains sufficient tannin (13 - 25%) for commercial exploitation.

A natural dye, used in the batik textile industry in Indonesia, is also extracted from the bark

The wood is excellent for turnery articles, toys, carom coins, chessmen and handicrafts. It is also used for furniture, joinery, tool handles, and for construction if trees of suitable girth are available.

The wood is extensively used for paper pulp. Plantation-grown trees have been found promising for the production of unbleached kraft pulp and high-quality, neutral, sulphite semi-chemical pulp.

A major source of firewood and provides very good charcoal that glows well with little smoke and does not spark.
