This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Most of the entries on this atlas's own Customary Law page describe systems that operate alongside a state's formal law, tolerated, sometimes deferred to for particular disputes, but rarely written directly into the statute books of a common law nation as a recognized source of legal right. The Native Title Act 1993 is the exception worth sitting with, because it does something unusual: it takes rights held under Aboriginal and Torres Strait Islander traditional law and custom and gives them a determinate legal test, a tribunal, and a right to negotiate inside the ordinary machinery of Australian federal legislation.
The mechanics matter here more than the politics. To establish native title under the Act, a claimant group generally has to show a continuous connection, under their own traditional laws and customs, to the specific land or waters claimed, from a time before European sovereignty was asserted, through to the present. That test asks an Australian federal tribunal or federal court to make findings about the content and continuity of an indigenous customary legal system on its own terms, not by translating it into the categories of English land law. A claim can succeed, be extinguished by a valid prior government act such as a freehold grant, or coexist with another interest, as the High Court held a pastoral lease could in Wik Peoples v Queensland (1996), each outcome turning on how the common law and the underlying customary system interact on a specific piece of ground.
That is a genuinely difficult thing for any legal system to do well, and Australia's own record on it is contested rather than settled. Indigenous advocates and many scholars argue the extinguishment doctrine still lets too much prior colonial dispossession stand undisturbed, and the 1998 Ten Point Plan amendments, passed after Wik, are frequently read as narrowing the practical reach of native title rather than merely clarifying it. What is not contested is the structural achievement: a common law jurisdiction built a statute whose entire operation depends on a court being able to find, as a matter of proven fact, what a customary law system actually says, and then giving that finding real legal consequence, land rights, a negotiating position, sometimes compensation, rather than folding the customary claim into an existing common law category that was never built to hold it.
