Caloprymnus campestris is thought to occupy a relatively small area in Southern Australia, extending just over the borders of Queensland and Northern Territory. The coloring of the pelage of C. campestris is appropriate for its desert surroundings. The muzzle of C. campestris is short with large upper lips.
Ears are very long and covered with fur.
Neck glands have been observed in some specimens. A distinguishing feature of C. campestris is the difference in size between fore and hindlimbs. Forelimbs are quite delicate with bones weighing 1 gram, while hindlimbs are large with bones weighing 12 grams. This difference is related to saltation. Other characteristics related to hopping locomotion include the large difference in limb size, long tail, plantigrade hindfoot, and syndactyly.
