- Welcome to ASLIA National, the Australian Sign Language Interpreters Association. ASLIA was established to lead and to promote sign language interpreting across Australia. We want to ensure that interpreters are aware of their responsibilities and have adequate training and support to do a good job. We advocate for high quality interpreting work and for fair working conditions for our members. Historically, ASLIA has been focused on hearing interpreters, working between Auslan and English, but now we're extending to include the work of our deaf interpreting colleagues as well. Sometimes, sign language interpreters work independently, sometimes in teams various combinations, and always in very different situations.
