A fast growing species which will set abundant seed however it may often be firmly lodged in the pods. The seed collector will usually require a mechanical means of threshing the pods. The primary concern then is to avoid damage to seed.

"Grows on rainforest margins, open forest, scrub-forest, in valleys or on hillsides, often in sandy or volcanic soils. Flowers anytime of the year; fruits Sept.–Dec." (WorldWideWattle ver. 2)

Within our area of operation we observe Acacia irrorata subsp. irrorata on shallow to deep soils of lateritised basalt, sandy loams from granitic parent rock and clay loams on metamorphics (schist, slate, mudstone).
