Norman Tindale referred to material by two early correspondents, Urquhart and O'Reilley, in a publication by E. M. Curr for details about the Wakabunga and their language, but the word-list is not considered to contain elements of this tongue, about which the general belief is that no information survives. It has been suggested by Barry Blake however,[1] that a word-list compiled in the Wakabunga domain by Curr's brother Montagu Curr,[2] belong to a Mayi dialect. From this it has been inferred that Wakabunga may have belonged to the Mayi language family.
According to Norman Tindale they were related to the Kalkatungu.[3] They were crocodile hunters, stalking freshwater crocodiles with spears on the upper Leichhardt.[4]
