These centres operate to provide free legal services and education to meet the needs of the community. They are supervised by full-time and part-time qualified legal practitioners, but are essentially run by law students at the Faculty of Law. Working at one of these centres for a semester or a summer is part of the Faculty of Law's Professional Practice units, which are credited towards the Bachelor of Laws. Student volunteers undertake a range of responsibilities, including interviewing clients, negotiating with other parties, letter drafting, preparing wills and court documents, and appearing in court on their client's behalf. Although most tasks are carried out by the students, they are under the supervision of practising solicitors. The Centres provide legal advice in areas such as criminal law, employment law, debt and family law. They also produce publications on law reform.
