Auslan, BSL and NZSL have 82% of signs identical (using concepts from a Swadesh list). When considering similar or related signs as well as identical, they are 98% cognate. Further information will be available after the completion of the BSL corpus is completed and allows for comparison with the Auslan corpus and the Sociolinguistic Variation in New Zealand Sign Language project . There continues to be language contact between BSL, Auslan and NZSL through migration (deaf people and interpreters), the media (television programmes such as See Hear, Switch, Rush and SignPost are often recorded and shared informally in all three countries) and conferences (the World Federation of the Deaf Conference – WFD – in Brisbane 1999 saw many British deaf people travelling to Australia).
