Auslan /ˈɒz læn/ is the sign language of the Australian deaf community. The term Auslan is an acronym of "Australian Sign Language", coined by Trevor Johnston in the early 1980s, although the language itself is much older. Auslan is related to British Sign Language (BSL) and New Zealand Sign Language (NZSL); the three have descended from the same parent language, and together comprise the BANZSL language family.
