What is "kaurareg"

The Kaurareg (alt. Kauraraiga), also the Kauraraigalai, in the modern dialect Kaiwaligal (singular form Kauraraiga, modern dialect Kaiwalaig), are an indigenous Australian group of Torres Strait Islander people who are united by a common language, strong ties of kinship and survived as skilled hunter–fisher–gatherers in family groups or clans living on a number of inner Torres Strait Islands. They are descendants of indigenous Australians who had either settled some 3,000 years ago in Torres Strait, or remnants of pre-Ice Age Australian-Papuans, or both, who had intermarried with Papuo-Austronesian settlers who colonised Torres Strait around 2,800 years ago.
