It is a spreading shrub or small tree with egg-shaped to elliptic leaves, male and female flowers on separate plants, male flowers with about 30 stamens, female flowers with about 35 carpels, and the fruit is a glossy, olive-black drupe with an orange fruiting receptacle.

Its leaves are egg-shaped with the narrower end towards the base to elliptic, 60–210 mm (2.4–8.3 in) long and 20–70 mm (0.79–2.76 in) wide on a petiole 5–15 mm (0.20–0.59 in) long, the edges of the leaves irregularly toothed and with a prominent mid-vein.

Male and female flowers are borne in leaf axils on separate plants, male flowers in clusters of 7–9, 20–30 mm (0.79–1.18 in) long, the individual flowers 4–5 mm (0.16–0.20 in) in diameter on a pedicel about 8 mm (0.31 in) long, with about 30 stamens.

[2][3] Wilkiea austroqueenslandica was first formally described in 1926 by Karel Domin in Bibliotheca Botanica, from specimens collected on Tamborine Mountain.

[4] This species of Wilkiea grows in rainforest at altitudes up to 850 m (2,790 ft) from the McPherson Range in south-east Queensland to the Richmond and Tweed Rivers in north-eastern New South Wales.
