The cylindrical flower-spikes have a length of 3 to 8 cm (1.2 to 3.1 in) with creamy coloured flowers that occur in interrupted bands.

Following flowering flat and spirally coiled seed pods form that have a width of 3.5 to 5 mm (0.14 to 0.20 in) are glabrous and covered in a fine white powder.

[1] The species was first formally described by the botanist Jacques Labillardière in 1825 as part of the work Sertum austro-caledonicum.

It was reclassified by Leslie Pedley in 1987 as Racosperma spirorbis and then transferred back to genus Acacia in 2006.

The tree is usually situated along the margins of rainforest communities or as a part of Eucalyptus woodlands in drier areas.
