A demographic survey of speech pathologists was conducted in Australia to investigate the use of augmentative and alternative communication (AAC) with adults with acquired neurologic communication disabilities. Questionnaires were distributed to all speech pathologists who were members of the Australian Association of Speech and Hearing and listed themselves as working with an adult or mixed caseload. Questions related to the clinician's background, experience and interest in AAC, knowledge of and expertise with high and low technology systems, and factors related to successful outcomes for clients. Subjective data from the questionnaire were collated and the results and their implications are discussed.
