Eucalyptus oraria is a mallee, rarely a tree or low shrub that typically grows to a height of 1–15 mm (0.039–0.591 in) and forms a lignotuber.

[2][3][4] Eucalyptus oraria was first formally described in 1962 by Lawrie Johnson from specimens he collected near Dongara in 1960.

The specific epithet (oraria) is from the Latin orarius meaning "pertaining to the coast".

[5] Ooragmandee grows in sand in coastal and near-coastal areas, often over limestone and is found from near Jurien Bay to near Kalbarri and on some nearby offshore islands.
