It is an assumption universally shared that Deaf, Deafblind and hard of hearing people all have similar, if not the same, communication skills. Just like any other CALD community in society there is a rich diversity of communication skills in the Deaf community. It is also assumed that, if an Auslan interpreter is NAATI certified they are therefore sufficient for the communication needs of a Deaf client. This Position Paper clearly sets out the reasons for why this assumption is incorrect and can even cause harm.
