A description of the species was first published in 1915 by Oldfield Thomas, his notes on two bat genera resulting in a new subspecies Taphozous australis georgianus.

[3][4] The taxon was included in a revision by Ellis Le Geyt Troughton (1925)[5] that proposed recognition as a species and this status was acknowledged in 1967.

[3] The holotype, the skull and skin of a female, is held at the British Museum of Natural History and the locality of the collection noted as King George Sound; the species has not been recorded at this location.

[6] A pouch is found at the radial-metacarpal, a gular sac is absent,[6] The interfemoral membrane covers most of the tail, the tip is bare and prominent.

[8] The roosting position distinguishes it from similar bats, they lay their body close to the surface with the forearms stretched out and shoulders raising the head up.

The species occupies crevices at vertical faces or at the roof in horizontal mine and caves, and prefers the darkest parts of the site.

An individual or group's range may vary during the year; they appear to seasonally vacate some residences and relocate to other local sites.

Taphozous georgianus and many other species can be hooked through the easily torn wing membranes; many individuals meet with an often slow demise each year from this widely used and discarded fencing material.

[8] Other threats include the destruction of roosting areas by mining, disturbance by human intrusion, and introduced land management practices that result in the dilapidation of the local ecology.
