What is "kuringgai"

Kuringgai (also spelled Ku-ring-gai, Kuring-gai, Guringai) , a group of indigenous people of Australia, are those Australian Aborigines that were united by a common language, strong ties of kinship and survived as skilled hunter–fisher–gatherers in family groups or clans scattered along the coastal area of what is now known as the Sydney basin, in New South Wales, Australia. Their traditional territory spreads from the north of Sydney Harbour, through Lane Cove River, Middle Harbour, Pittwater, the Hawkesbury River, Broken Bay, Brisbane Water, and Central Coast to north of Tuggerah Lakes.
