Kalkatungu (also Kalkutungu, Galgadungu, Kalkutung, Kalkadoon, or Galgaduun) is an extinct Australian Aboriginal language formerly spoken around the area of Mount Isa and Cloncurry, Queensland.
[1][2] Apart from the closely related language, Wakabunga, Kalkatungu is sometimes grouped with Yalarnnga as the Kalkatungic (Galgadungic) branch of the Pama–Nyungan family.
Emeritus Professor Barry Blake, Sheree Blackley[5] and others have revived the language based on recordings, written grammars and personal memories.
Robert Ah Wing, assisted by Uncle Arthur Peterson[6] is also active in this field.
Often, emphasis is placed on belonging, passing on elements of language to younger Kalkatungu.
