The eastern or Queensland tube-nosed bat is a megabat in the family Pteropodidae that lives in north-eastern Australia. N. robinsoni is one of the few species of megabat that roosts solitarily. They get their common name from their raised tubular nostrils which are unlike those of most other species in the family. They are a deep brown with gray heads and sparse yellow spotting.

Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or—especially the genera Acerodon and Pteropus—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described.
