Sign languages appear to be most developed in areas with the most extensive speech taboos: the central desert (particularly among the Warlpiri and Warumungu), and western Cape York.1 Complex gestural systems have also been reported in the southern, central, and western desert regions, the Gulf of Carpentaria (including north-east Arnhem Land and the Tiwi Islands), some Torres Strait Islands, and the southern regions of the Fitzmaurice and Kimberley areas. Evidence for sign languages elsewhere is slim, although they have been noted as far south as the south coast (Jaralde Sign Language) and there are even some accounts from the first few years of the 20th century of the use of signs by people from the south west coast. However, many of these sign languages are now extinct, and very few accounts have recorded any detail.
Reports on the status of deaf members of such Aboriginal communities differ, with some writers lauding the inclusion of deaf people in mainstream cultural life, while others indicate that deaf people don't learn the sign language and, like other deaf people isolated in hearing cultures, develop a simple system of home sign to communicate with their immediate family. However, an Aboriginal and Torres Strait Islander dialect of Auslan exists in Far North Queensland (extending from Yarrabah to Cape York), which is heavily influenced by the indigenous community sign languages and gestural systems of the region.
Australian indigenous sign languages in north Queensland were noted as early as 1908 (Roth). Early research into indigenous sign was done by the American linguist La Mont West, and later, in more depth, by English linguist Adam Kendon.
