This lies between Auslan and Signed English, as the name suggests. Johnston [Joh89] points out that there is a continuum between Auslan and Signed English and that members of the Deaf community will attune where they sign on the curve depending on who they are speaking to. Between two Deaf people, for example, the conversation would lie very much to the right of the curve, in the domain of Auslan. Between Deaf and speaking persons, they would use something somewhere in the middle, whereas full-on Signed-English speakers would be on the left.
