South Australia legal data from official sources, structured for AI and legaltech.

South Australia is a common-law jurisdiction within Australia's federal system, applying Australian common law alongside statute enacted by the bicameral Parliament of South Australia — the House of Assembly and the Legislative Council. Primary legislation — Acts and subordinate regulations — is published on the official South Australian legislation website (legislation.sa.gov.au), maintained by the Office of Parliamentary Counsel, and notified in the South Australian Government Gazette. The court hierarchy runs from the Magistrates Court and District Court up to the Supreme Court of South Australia, which since 1 January 2021 has had a permanent Court of Appeal as its appellate division; specialist bodies include the Environment, Resources and Development Court, the Coroners Court, the Youth Court, and the South Australian Civil and Administrative Tribunal (SACAT). Regulatory policy sits with agencies such as Consumer and Business Services, SafeWork SA, the Essential Services Commission of South Australia, the Environment Protection Authority, and RevenueSA. Legislation and decisions are published in English.

South Australia has an outsized place in legal history — it originated the Torrens system of land title by registration through the Real Property Act 1858, now consolidated in the Real Property Act 1886 (SA), and was the first jurisdiction in the world to grant women both the vote and the right to stand for parliament. Its statute book keeps changing, from anti-discrimination law under the Equal Opportunity Act 1984 (SA) to reforms in planning, work health and safety, and criminal justice, so citations to a superseded reprint can be wrong. Point-in-time versions straight from the official source — the South Australian legislation website already publishes historical and 'as made' versions — are what keep a South Australian legal research answer correct today.
