[3][4] Few features distinguish the allied rock-wallaby from its close relatives but each species lives in a different part of Queensland and northern New South Wales; where their ranges overlap slightly, there is some hybridisation.

[2] Typical habitat is mountainous areas with cliffs, ledges, caves and rock piles.

[4] The allied rock-wallaby is behaviourally monogamous, but not all the offspring are sired by the supposed father.

The gestation period is about thirty days, the joey leaves the pouch at six to seven months and is fully weaned when nearly a year old.

[2] Some factors that affect rock wallabies are climate change, which may alter the flora of their habitat, introduced predators such as dogs and foxes, degradation, loss and fragmentation of habitat, competition from introduced grazing animals and changing practices for periodic burning.
