Unidentified

Hi, Your photo certainly shows well that it is one of the freetail bats (tail not fully enclosed in the membrane between the hind legs), but as to which species it is, I wouldn't necessarily trust that ID. This group has been revised recently and I don't have the details. Our most recent edition of mammals field guide still calls this group Mormopterus and has two species as occurring in this area, norfolkensis (East-coast Freetail Bat) and an undescribed species (possibly Mormopterus ridei, but with a new genus name by now, but I don't know it), the Eastern Freetail Bat. I doubt these two could be distinguished from this photo. The taxonomy has been a mess according to Wikipedia and Mormopterus is now not regarded as present in Australia, but only norfolkensis went into Micronomus, so god knows what the rest, including ridei, are now called.
