The female weighs 460 g (16 oz) while the male weighs 400 g (14 oz). They have dark brown or tan upper parts with pale spots. They have black and tan bars on its wings and a very pale beak, feathered legs, and dark brown eyes. Like all Tyto owls, it has a heart-shaped facial disk with brown buff and a white bordering.

This owl prefers tall grasslands and swamps. Roost areas consist of flattened vegetation within systems of "tunnels" through the swamp vegetation. Nesting is in similar situations.
Eastern grass owls are considered "least concern" globally, primarily because of their wide distribution. Within Australia, Tyto longimembris is considered vulnerable on the New South Wales Threatened Species Conservation Act (1995).
