The Olive-backed Oriole is part of a worldwide family, of which Australia has two other members (the Yellow Oriole and the Figbird). Males and females have an olive-green head and back, grey wings and tail, and cream underparts, streaked with brown. They both have a bright red eye and reddish beak. Females can be distinguished from males by a paler bill, duller-green back, and an extension of the streaked underparts up to the chin.
Olive-backed Orioles have a reddish bill, which easily distinguishes the species from the similar Figbird Sphecotheres viridis, which has a blackish bill. It also lacks the Figbird’s bare eye skin and has red rather than dark eyes.
