Bettongia setosa (Gray 1837) is the extant bettong, a kangaroo ancestor derived from Potorous.

Lagostrophus fasciatus (originally Lagorchestes fasciatus Thomas 1887) is the extant banded hare-wallaby. Note the descending process of the maxilla below the jugal.

Dendrolagus ursinus (Müller 1840; up to 82 cm snout-vent length+ up to 94 cm tail) is the extant black tree kangaroo.

Balbaroo nalima (Flannery, Archer and Plane, 1983; Black et al. 2014, middle Miocene; 12 cm skull length; QM F36295) was originally considered a genus of extinct kangaroo, probably a quadruped. That is confirmed by the LRT. With low-crowned molars, it was a browsing herbivore. Balbaroo retained a small canine.

Macropus giganteus (Shaw 1790, extant) is the eastern gray kangaroo. The forelimbs were elongated. The hind limbs even more so. The pedal digits were reduced, all but the second digit, which was robust. Kangaroos hop bipedally and rest tripodally with the tail. Note the pelvis is essentially vertical here and the proximal femur was lower than the distal femur.

The canines were absent and a diastema separated the incisors from the molars, convergent with rodents and multituberculates. The lower incisors were elongated and procumbent.
