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. 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.
