AustLII vs CourtListener

AustLII is a free web library for Australasian legal information, established in 1995 by the law faculties of UTS and UNSW and supported by the AustLII Foundation Ltd. Its collections include cases, legislation, treaties, law journals, law reform reports, and other legal content from Australia and New Zealand, including New Zealand material from the New Zealand Legal Information Institute. Users can search all databases together, search them separately, filter by jurisdiction, or work within one database. Search syntax includes Boolean connectors, proximity operators, truncation, and phrase searching. The integrated LawCite citator follows citations to Australian cases, journal articles, and other materials across AustLII and collaborating legal information institutes. Document pages offer print, download, and cited-by links. The responsive site is intended for current device types. AustLII identifies law librarians, academic researchers, practitioners, government officers, and policy advisers among its users.
