Regenerates from seed.
Tree 5–30 m tall. Leaves dorsiventral. Juvenile and intermediate leaves 28–40 cm long, 150–300 mm wide across lobes, 3–5-fid or 3–5 (–10)-partite with narrowly oblong to narrowly ovate ascending lobes 10–25 cm long, 10–50 mm wide, rarely some secondary division. Adult leaves usually entire, narrowly oblong to slightly narrowly obovate, 9–24 cm long, 15–60 mm wide; margins shortly recurved; surfaces dissimilar, with lower surface sericeous, silvery grey. Conflorescence terminal or axillary, erect to decurved, simple or rarely few-branched; unit conflorescence cylindrical, 9–22 cm long, weakly acropetal to subsynchronous. Flowers transverse on rachis. Flower colour: perianth green in late bud becoming white to cream; style cream to white. Perianth sericeous outside, glabrous inside or papillose to minutely pubescent towards base. Nectary arcuate. Pistil 13.5–16 mm long, glabrous; pollen-presenter very oblique, convex. Follicle compressed-ovoid to -broadly ellipsoidal, 17–26 mm long, glabrous, rugulose, not viscid.
Occurs in near coastal eastern Australia from Cooktown, Qld, S to the Brunswick R. in northern N.S.W. Grows in and on margins of rainforest communities, often in deep fertile soils. Flowers erratically, mainly July–Oct.? Map 352.

Grevillea hilliana can be confused with G. baileyana (both have leaves penninerved below), but G. baileyana has rusty brown hairs on the lower leaf surface, usually much-branched conflorescences, a shorter pistil 9–13.5 mm long, and pericarp < 1 mm across at the suture (> 1.5 mm across in G. hilliana ). The timber of G. hilliana has been used in the past for cabinet work and veneer.
