Eucalyptus aequioperta is a mallee or sometimes a tree growing to a height of 5 to 8 metres (16 to 26 ft) or more, and forms a lignotuber. The bark is a dark grey colour, firm and flaky to fibrous over the lower half of the trunk and extending to large limbs. The bark becomes slightly tessellated on older trees and on higher branches is smooth, dull and pinkish grey to white. Adult leaves are lance-shaped, glossy and a similar green on both sides. The leaf blade is linear to narrow lance-shaped or curved, 60–110 mm (2–4 in) long and 6–12 mm (0.2–0.5 in) wide with a petiole 8–17 mm (0.3–0.7 in) long. The flower buds are arranged in groups of between seven and fifteen in leaf axils, the groups on a peduncle 5–15 mm (0.2–0.6 in) long, individual buds on a pedicel 2–5 mm (0.08–0.2 in) long. The buds are "egg-in-egg cup shaped" or spindle-shaped, 5–7 mm (0.20–0.28 in) long and 2.5–3.5 mm (0.098–0.14 in) wide. The operculum is 1.5–3 mm (0.06–0.1 in) long and equal in width or narrower than the floral cup. The stamens are white. Flowering has been observed in May and the fruit are cup-shaped to cone-shaped with the narrower end towards the base, 4–5 mm (0.16–0.20 in) long and 5–6 mm (0.20–0.24 in) wide.
