Along with possums, gliders, potoroos, and kangaroos, the Lake Mackay hare-wallaby belongs to the suborder Phalangerida.

They allegedly sheltered in shallow depressions below clumps of spinifex, created grass-lined nests, and sometimes dug short burrows similar to those of the Rufous hare-wallaby.

[6] The Lake Mackay hare-wallaby was said to have eaten grass leaves and seeds and desert quandong fruit.

In addition to predators, the introduction of rabbits to central Australia also strained the populations of Lake Mackay hare-wallaby by creating competition over resources such as food and shelter.

The droughts that affected Central Australia in the 1900s were responsible for a surge of forest fires which can also be attributed to the decline of the Lagorchestes asomatus.

Large grass tussocks, which were used by the Lake Mackay hare-wallabies for shelter, were removed for Australia's pastoral industry.

[6] The land in these regions is primarily sandy clay soils filled with salt and halophytic grasses and shrubs.

[9] In 2001 there was an effort to reintroduce two species of hare-wallaby, the mala (Lagorchestes hirsutus) and the mernine (Lagostrophus fasciatus).

The results of the study demonstrated that the variation and flexibility of habitat selections were such that future re-introductions wouldn't have to adhere to very strict areas that have vegetation at a high density.
