They are endemic to Australia, are insectivores and have a broad range within the mainland, mainly in hot arid areas but also found in tropical rainforests.

[3][4] Scotorepens greyii individuals have a slender body shape, a broad square muzzle when viewed from above and have varied fur colouring.

[3][4][2][5][6] Little broad-nosed bats are known to roost in hollows, usually in trees but they have also been found in fence posts and in the space under metal caps of telegraph poles.

[3] Despite its small size, the little broad-nosed bat is able to survive the extreme summer temperatures in its arid Australian environment by utilizing torpor and roost selection to conserve energy.

[7] Torpor helps the bats retain body water and reduces heat production from metabolic reactions.

Roosting in poorly insulated dead trees allows solar radiation to rouse them instead of physical activity.

They frequently give birth to twins and the young bats are capable for foraging within one to two months.
