Native to New South Wales and Queensland. Erect stem with rough bark the phyllodes have a hooked tip.

Similar to Acacia boormanii which has bright yellow flower heads and grey-green phyllodes, and to Acacia meiantha which has brighter yellow flower heads and branchlets and peduncles with short stiff hairs.
