This bat inhabits a wider strip of land along the east coast of Australia . It lives in rainforests , in regions with hard-leaved plants and in areas with eucalyptus plants .

There are tree hollows, crevices in the rocks, hiding places behind detached tree bark and house roofs as resting places. The individuals begin their hunt for beetles and other flying insects shortly after sunset. Sometimes they eat smaller vertebrates . A litter usually consists of a young that is born in the Australian summer.

Deforestation and the destruction of suitable resting places have a negative impact on the population of the great broad-nosed bat. The International Union for Conservation of Nature (IUCN) lists the species as not endangered despite a decline in the population ( least concern ).
