The average banded hare-wallaby weighs 1.7 kg, with females weighing more than males.

The banded hare-wallaby has a short nose.

The banded hare-wallaby reaches maturity at one year of age, breeding usually starts in the second year.

This new subfamily includes the banded hare-wallaby and the fossil genus Troposodon.

The banded hare-wallaby is nocturnal and tends to live in groups at nesting sites; this species is quite social.

The island is home to one of the few remaining colonies of the Banded Hare-wallaby (Lagostrophus fasciatus).

It includes all living members of the Macropodidae except for the Banded Hare-wallaby (Lagostrophus fasciatus), the only surviving member of the subfamily Sthenurinae.

The banded hare-wallaby or mernine (Lagostrophus fasciatus) is a marsupial that is currently found on the Islands of Bernier and Dorre off western Australia.

There are two living subfamilies in the Macropodidae family: Lagostrophinae is represented by a single species, the Banded Hare-wallaby; the remainder, about 60 species, makes up the subfamily Macropodinae.

However, sub-fossil evidence of the former presence of native mammals has brought reintroduction of the Boodie, Shark Bay Mouse, Banded Hare-wallaby and Western Barred Bandicoot and Greater Stick-nest Rat.

The banded hare-wallaby (Lagostrophus fasciatus) is thought to be the last remaining member of the once-numerous subfamily Sthenurinae, and although once common across southern Australia, is now restricted to two islands off the Western Australian coast which are free of introduced predators.

Evidence suggested that the mernine was the only living member of the Sthenurine subfamily, and a recent osteology-based phylogeny of Macropodids found that the banded hare-wallaby was indeed a bastion of an ancient lineage, agreeing with other (molecular) appraisals of the evolutionary history of L. fasciatus.

Although the banded hare-wallaby was once found across the south-western portion of Australia, it is believed to have been extinct on the mainland since 1963, and the last recorded evidence of the banded hare-wallaby on the Australian mainland was in 1906.
