Diprotodon superficially resembled a rhinoceros without a horn.
Its feet turned inwards like a wombat's, giving it a pigeon-toed appearance.
It had strong claws on the front feet and its pouch opening faced backwards.

Until recently, how many species of Diprotodon had existed was unknown.
Eight species are described, although many researchers believed these actually represented only three at most, while some estimated about 20 in total could exist.

John Walter Gregory collected stories of mystical creatures in Aboriginal myths and legends and considered the possible connections between them and extinct species.
He reported a story of  a "big, heavy land animal, with a single horn on its forehead" as a possible reference to Diprotodon; the presence of a horn on the rostrum of the species is not scientifically acknowledged.

The skull of Diprotodon has large endocranial sinus cavities, which separate the relatively small cranial vault from the outer part of the skull.
These significantly lighten the skull while providing large areas for muscle attachment and reduce load stress.
