or any part of them". A further complexity is introduced in a form of ranking of rights, for example in New South Wales, a traditional owner must be both born in the country and have a cultural association with the land. Peter Sutton distinguishes between "core" and "contingent" rights, which he says are recognised among most Aboriginal peoples. So there are sometimes challenges in finding "the right people for the right country", complicated by the fact that there are cases where both primary and secondary rights holders are described by the term. Distinguishing between "historical people" and others who have been custodians of the land for many generations add to the complexity. In the case of some agreements, historical people may be recognised as parties even when they don't have "traditional" associations with the land. The term Traditional Owner Corporation (TOC) is used to refer to various types of Aboriginal and Torres Strait Islander corporations. Such a corporation is usually the negotiating body when determining native title outcomes. (A TOC is distinct from the Registered Native Title Body Corporate (RNTBC), which manages the land after a native title determination has been made.) In Victoria, a "traditional owner group" is defined in the Traditional Owner Settlement Act 2010 to include those people recognised by the Attorney-General as traditional owners, based on their traditional and cultural associations with the land, and there are government guidelines detailing what these terms mean. They state that traditional "Denotes linkages with the past that are actively kept alive by the traditional owner group members. It is not restricted to features or activities understood to be fully continuous with, and identical to, such activities or features in pre-contact Aboriginal society". Apart from the legal definitions, the terms traditional owners or traditional custodians of the land are included in Acknowledgment of Country wording which is used to pay respects to the people of that Country. Examples of alternative settlements South West Native Title Settlement for Noongar people in Western Australia aims to resolve native title claims in exchange for statutory recognition of the Noongar people as the traditional owners of south-Western Australia. it is the largest native title settlement in Australian history, affecting about 30,000 Noongar people and encompassing around in south-western Western Australia. It has been described as "Australia's first treaty". An Indigenous Land Use Agreement (ILUA) was agreed with the Kaurna Yerta Aboriginal Corporation (KYAC) in
