 '''Acacia ''crassicarpa''''' occurs in northern Queensland, the Torres Strait islands, and New Guinea.  In Queensland it extends from Badu, Banks, Horn and Prince of Wales Islands in Torres Strait and Cape York Peninsula S to Townsville; southern outliers occur at the Burdekin River (south west of Ayr), Whitsunday Island and from Slade Point near Mackay.

 In New Guinea it occurs in the southern lowlands from south-eastern Irian Jaya, Indonesia, and E to the Oriomo River region of Papua New Guinea.

 Bark deeply rimose. Dead bark layered. Living bark strong and fibrous. Branchlets sometimes pendulous, glabrous.
 Throughout its range '''A. ''crassicarpa''''' is variable in habit and the size of its phyllodes and pods. For example, on Lizard Island, Qld, the type locality, growth habit appears strongly affected by wind shear: small trees with relatively short trunks and spreading canopies are characteristic. Relatively small pods (4–8 cm long; 1.3–2 cm wide) are also typical. A specimen collected from Palfry Island, Qld, has atypically narrow phyllodes (7–8 mm wide).

 '''Phyllodes''' vary from 8 to 27 cm in length, (0.7–) 1–4.5 cm wide, and have about 7 veins more prominent than the rest. Phyllodes normally lanceolate-falcate, narrowly tapered at base above the pulvinus, glabrous, pale green to grey-green; longitudinal nerves numerous and closely parallel (not anastomosing), 4–6 per mm; pulvinus (5–) 8–16 mm long, phyllode lamina blending gradually into the pulvinus.
-'''Pods''' are oblong to narrowly oblong, flat, woody, (3–) 4–12 cm long, (1–) 2–4.5 cm wide, dehiscing along ventral suture, the nerves transverse to transversely oblique, crowded and numerous.

In the absence of pods A. crassicarpa may resemble specimens of [[Acacia meiosperma]] which have falcate phyllodes.
 '''Seeds''' traverse, obloid to ovid, glossy black, 5–6 mm long, 3–4 mm wide, +/- terete, arranged separately in separate compartments and their arils are cream to white, ageing cream or pale yellow. Funicle/aril many-folded, 5–20 mm long (unextended), seed is produced in abundance after 4 years. The seeds mature 5–6 months after flowering.

 '''Inflorescence''' are bright yellow spike, 4–7 cm long, clustered in groups of 2–6 or so in the upper axils. Peduncles 3–10 mm long, glabrous; spikes (2–) 3–7 cm long, +/- interrupted, light golden to pale yellow. Flowers 5-merous; calyx gamosepalous; ovary densely hairy on upper half. The flowers are bisexual. Flowering starts as early as 6 months after the tree is established.

 == Other uses ==
 This tree is a vigorous nitrogen-fixer and nodulates well. The leaves decompose slowly, and are useful as mulch. The wood from the tree dries out moderately quickly and is useful for firewood and charcoal. It also makes good wood-pulp, better from the softer wood of plantation-grown trees than from the native ones. The sapwood is pale yellowish brown and the heartwood golden brown. The wood is suitable for a wide range of sawn-timber end uses, for light construction, furniture, flooring and boat-building.
