ANTAC is registered under the Corporations (Aboriginal and Torres Strait Islander) Act 2006. ANTAC is a registered charity accredited by the Australian Charities and Not-for profits Commission as a Public Benevolent Institution (PBI) and Deductible Gift Recipient (DGR).

ANTAC is governed by a unique system of Indigenous governance, which blends Aboriginal traditional cultural governance components, and the requirements of non-Indigenous governance models. ANTAC integrates the fundamental ingredients for effective contemporary Indigenous governance in its governance model and organizational structure. ANTAC’s Indigenous governance model incorporates two bodies of law: the CATSI Act 2006 and Ngangka?iku Tjukurpa (Ngangka?i Law).

The CATSI Act 2006 provides the federal legal framework on Indigenous corporate governance. ANTAC complies with the rules of the Act in relation to its organisational governance system that includes its organisational structure, decision-making mechanisms and processes, internal and external accountability.

The Ngangka?iku Tjukurpa encompasses the whole Aboriginal traditional knowledge system that defines and regulates the ngangka?i’s traditional medical system, its methods of healing and treatment, code of conduct, educational and training system. Ngangka?iku Tjukurpa is the primary body of law held by the ngangka?i and passed down from generation to generation since time immemorial. It provides the foundational rules by which the ngangka?i members of the A?angu Ngangka?i Tjutaku Aboriginal Corporation operate.

The CATSI Act 2006 and Ngangka?iku Tjukurpa provide the legal foundations under both federal law and Aboriginal customary law. These bodies of law coexist within ANTAC’s Indigenous governance and organisational structure and govern its decision-making processes and mechanisms, management, service delivery activities, internal and external accountability.
