Indigenous Australian sign languages and Auslan
A number of Indigenous Australian sign languages exist, unrelated to Auslan, such as Warlpiri Sign Language and Yolngu Sign Language. They occur in the southern, central, and western desert regions, coastal Arnhem Land, some islands of the north coast, the western side of Cape York Peninsula, and on some Torres Strait Islands. They have also been noted as far south as the Murray River.
