This publication arises from a research alliance between Legal Aid NSW and the Law and Justice Foundation of New South Wales and was developed to support Legal Aid NSW undertake a review of their client intake and triage services. Within the context of demand for services outstripping supply, triage is a valuable approach for Legal Aid NSW to match potential clients to services appropriate to their legal need and capability. But to triage appropriately, Legal Aid NSW needs a clear understanding not only of who they seek to serve, under what circumstances and for what issues and to what level, but also what resources and assistance other services offer. Drawing on the literature, the paper sets out triage principles. (See Table A1 below.) The paper provides a conceptual basis for further investigating and developing a systematic triage service model.
