Kuku Yalanji people are indigenous in Australia, originating from the rainforest regions of Far North Queensland and speaking the language Kuku Yalanji; also spelt Gugu Yalanji and here Guugu Yalandji as variants in English transliteration spellings. Guugu Yalandji language connects together their law, various dialects, clans and many communities. They also constitute one of the "Bama Rainforest Peoples". Kuku Yalanji live in coastal, riverine, and mountainous regions, their clan estates extending from Port Douglas in the south through to Cooktown in the north and to Chillagoe in the west. It is thought that there were three to five clans of Kuku Yalanji in 1770 prior to contact by Europeans, their diseases and colonisation.
