Aboriginal Heritage Act 1988

The Act casts a wide net. Primary duty-holders include owners and occupiers of private land (defined to include land subject to mining tenements or licences under the Hydrogen and Renewable Energy Act 2023), employees and agents of such owners, and any “prescribed person” acting under an authorisation (s 20A(9)). A body corporate that damages a site faces a $2 million maximum penalty (s 23(1)(a)); natural persons face $250 000 or two years’ imprisonment.

Developers, miners and infrastructure proponents are directly affected. Any activity that may uncover or disturb heritage triggers the need either to obtain a local heritage agreement plus authorisation or an approved agreement under Division A2. Holders of mineral claims, petroleum licences or hydrogen licences are expressly included within the extended definition of “owner” (s 3).

Recognised Aboriginal Representative Bodies occupy a central role. They must be consulted, may refuse to negotiate, are entitled to negotiate in good faith, and can enforce their agreements in the District Court (s 19K). Traditional owners retain independent rights to request prosecutions (s 45(3)), to be consulted on determinations (s 13(2)), and to object to the exercise of inspector powers over their sites (s 15(3)).

Inspectors appointed by the Minister (s 15) exercise entry, seizure, questioning and direction powers (s 17), including the new power to break into premises under warrant or in emergencies (s 17(1)(bb)). Magistrates issuing warrants and the District Court hearing enforcement applications are part of the enforcement ecosystem.

The Minister and the Aboriginal Heritage Committee hold overarching responsibility. The Minister must consult before making determinations or granting authorisations (s 13), maintain the Register, publish guidelines (Part 2A) and administer the South Australian Aboriginal Heritage Fund (s 19). The Committee advises, approves certain appointments, maintains a register of Recognised Bodies and can revoke appointments (ss 19E, 19G).

Land vendors must notify the Minister within 30 days of sale of land subject to Ministerial directions (s 24(10)). Collectors of Aboriginal objects owe a duty to take reasonable protective measures (s 28). Anyone who divulges information contrary to Aboriginal tradition commits an offence (s 35).

Finally, the Act affects Aboriginal people both as rights-holders (access, consultation, tradition protection) and, in limited cases, as potential defendants if they act as agents of a proponent and fail to comply with stand-down or reporting rules (s 20A(9)(b)).

Duties are both proactive and reactive. The owner or occupier of private land who discovers a site, object or remains must report “as soon as practicable” with particulars of nature and location (s 20(1)). A prescribed person acting under an authorisation who discovers new heritage or receives new information must immediately cease activity within the prescribed distance (three metres for a site, five metres for remains, or as specified), report, and not resume until the Minister has had a reasonable opportunity to act (s 20A). Excavation for the purpose of uncovering heritage requires Ministerial authorisation containing mandatory stand-down and reporting conditions (s 21). Intentional or reckless damage, disturbance or interference is an offence of strict liability in its lesser form (s 23(2)); the higher fault element carries heavier penalties (s 23(1)).

Persons in possession of objects must not sell or remove them from the State without authorisation (s 29). Reasonable measures must be taken to protect objects in collections (s 28). Directions of the Minister or an inspector must be obeyed (s 26). Interference with signs is prohibited (s 38).

Rights are conferred principally on traditional owners and Recognised Aboriginal Representative Bodies. Traditional owners’ views on significance according to Aboriginal tradition must be accepted by the Minister (s 13(2)). They may object to inspector powers (s 15(3)), request prosecutions (s 45(3)) and cannot have Ministerial acts invalidated for consultation defects by non-traditional owners (s 42). Recognised Bodies enjoy a statutory right to negotiate local heritage agreements and to refuse for any reason they think fit (s 19H(2)). They must be consulted before Ministerial directions (s 24(4)(ab)) and before appointment or revocation decisions.

Landowners and occupiers have procedural rights: reasonable notice before authorised entry for search or excavation (s 22(2)), opportunity to make representations before access authorisations (s 36(2)), and entitlement to compensation for damage caused by authorised persons (implicit in the Minister’s duty to “make good” damage under s 22(4)). Confidentiality of archive information is a right that can only be overridden in defined circumstances (s 10).

The Act preserves the fundamental right of Aboriginal people to act according to tradition notwithstanding its prohibitions (s 37).

Penalties are among the highest in South Australian environmental legislation. Damaging, disturbing or interfering with a site carries a corporate maximum of $2 million (s 23(1)(a)); the strict-liability offence attracts $50 000 for corporations (s 23(2)(a)). Failure to report a discovery or comply with stand-down rules under an authorisation attracts $500 000 for corporations and $250 000 or two years’ imprisonment for individuals (s 20A(4)). Unauthorised sale or removal of an object carries the same maximum (s 29(1)).

Inspectors may seize objects, use reasonable force, require names and addresses, and issue on-the-spot directions (s 17). New s 17A warrants authorise forced entry where a magistrate is satisfied there are reasonable grounds of contravention or evidence. Self-incrimination is no excuse for answering questions or producing documents, though derivative use immunity is provided (s 17B).

Part 3A adds flexible civil-like remedies on conviction: restoration orders, publication orders, compensation to Aboriginal parties, and disgorgement of economic benefit (including benefit obtained by delaying compliance costs) (s 37DA). Aboriginal heritage agreements and local heritage agreements are enforceable by the District Court without costs orders unless justice requires (ss 19K, 37D).

Prosecutions for summary offences may be brought up to three years after the event, or ten years with Ministerial authorisation (s 45(2)). Special rules apply on Aboriginal lands vested in statutory bodies: prosecutions generally require approval of the relevant land council (s 45(1)).

The Act is expressly designed to sit beside, and in some cases yield to, the Native Title Act 1993 (Cth). Registered native title bodies corporate are presumptively Recognised Aboriginal Representative Bodies (s 19B(4)). Indigenous land use agreements, future act agreements under Subdivision P, and native title mining agreements may be approved under Division A2, displacing ss 21 and 23 (s 19P). The definition of “owner” now includes holders of hydrogen and renewable energy licences (s 3), reflecting integration with the Hydrogen and Renewable Energy Act 2023.

Mining and petroleum statutes are directly referenced in the definitions of “mining tenement” and in the extended owner concept. The Mining Act 1971 and Opal Mining Act 1995 native title agreements can be approved to bypass heritage authorisations.

The Land Acquisition Act 1969 agreements relating to native title and prescribed private acquisitions may also be approved (s 19M(d)). Directions under the Act must have regard to existing authorisations, management methodologies, local heritage agreements and approved agreements under Division A2 (s 24(2a)), yet may override them to the extent of inconsistency while in force (s 24(1b)).

The Real Property Act 1886 is engaged by the registration of Aboriginal heritage agreements as encumbrances on title (s 37C). Confidentiality obligations interact with freedom-of-information legislation but prevail unless traditional-owner consent or Committee approval is obtained (s 10).

Section 42 limits collateral attacks on Ministerial acts based on consultation failures, thereby protecting decisions made under the Development Act 1993 or planning legislation from easy judicial review on heritage consultation grounds.

The Aboriginal Heritage (Miscellaneous) Amendment Act 2024 (commencing 1 January 2025) introduced the most significant overhaul since 2016. New ss 17A and 17B provide warrant powers and abrogate the privilege against self-incrimination (with use immunity). Section 20A was inserted to impose immediate stand-down and reporting obligations on persons acting under existing authorisations when new heritage is found; s 21 and s 23 were rewritten to mandate identical conditions in every authorisation. Part 3A creates additional court orders aimed at restoration, publicity and economic-benefit stripping.

Penalties were increased, the definition of “private land” and “owner” expanded to capture hydrogen and renewable energy projects, and consultation requirements updated. The 2016 Amendment had earlier inserted the entire Part 2B framework for Recognised Aboriginal Representative Bodies, Divisions A1–A3 for agreement-making, and the guideline power.

These changes respond to longstanding criticism that the original Act gave insufficient voice to Aboriginal communities, left too much discretion to the Minister, and lacked practical mechanisms to pause destructive works upon new discoveries. The 2024 reforms also strengthen enforcement in light of high-profile non-compliance cases in the resources sector and align the statute with contemporary co-management expectations.

The Act itself contains provisions that pre-empt certain controversies. Section 42 expressly prevents non-traditional owners from impugning Ministerial acts on consultation grounds, reflecting a legislative judgment that consultation duties are owed primarily to traditional owners. Section 11’s conclusive presumptions flowing from Register entries limit factual disputes in enforcement proceedings. The defence in s 23(4) — lack of knowledge and no reasonable expectation of knowledge — has been retained, although its practical availability is narrowed by the broad reporting and due-diligence obligations now contained in ss 20 and 20A.

Confidentiality of archives (s 10) and the prohibition on divulging tradition contrary to Aboriginal tradition (s 35) create tension with open government and procedural fairness. The statutory bar on using self-incrimination as an excuse (s 17B) will likely generate arguments about the scope of the derivative-use immunity in future prosecutions.

The interaction between Ministerial directions and pre-existing local heritage agreements or approved native title agreements (s 24(1b)) is a potential flashpoint. While the direction prevails to the extent of inconsistency, the agreement remains on foot and may still be enforced in the District Court, creating parallel and potentially conflicting obligations.

The priority rule in s 19C (strongest traditional affiliation) and the Committee’s broad discretion to refuse approval of native title bodies (s 19B(5)) are fertile ground for intra-Aboriginal disputes. The Act’s mediation encouragement (s 19C(2)) and requirement for bodies corporate with perpetual succession (s 19B(14)) attempt to manage these risks.

Most practitioners miss that a local heritage agreement does not itself authorise works; Ministerial approval of the agreement plus the consequent authorisation under s 19J is still required, and the authorisation is automatically conditioned on full compliance with the agreement (s 19J(1)). Another trap is the “prescribed person” definition in s 20A(9)(b)–(d): a traditional owner acting as employee or agent of a proponent becomes personally liable for stand-down breaches.

The Register’s conclusive effect (s 11) operates both ways: an entry conclusively proves the site is Aboriginal; a Ministerial determination not to enter conclusively proves it is not. Yet the Minister may still issue directions over non-Register sites (s 24(7)), creating a parallel protection pathway outside the Register.

Section 13(2) mandates that the Minister “must accept the views of the traditional owners” on significance according to tradition when determining whether land or an object qualifies. This is not a mere procedural requirement; it is a substantive rule of decision that removes Ministerial discretion on that element.

The economic-benefit order in s 37DA(1)(e) expressly captures benefit obtained by “delaying or avoiding costs”. A proponent who proceeds without proper authorisation to save delay costs can therefore be ordered to pay the avoided compliance expense even if no actual profit was made.

Finally, the ten-year extended limitation period (s 45(2)) applies only with Ministerial authorisation and only to summary offences. Indictable offences (those carrying two-year imprisonment maxima) are unaffected by the three-year cap.

Compliance begins with due diligence. Proponents should interrogate the central and local archives (subject to confidentiality rules) and, where uncertainty exists, lodge a s 12 application for a Ministerial determination. If the proposed activity may affect heritage, identify the Recognised Aboriginal Representative Body from the Committee’s register (s 19G). Early engagement is essential: the Body may refuse to negotiate, in which case the conventional authorisation route must be followed.

Where negotiation occurs, the local heritage agreement must satisfy the content requirements of the regulations and the Aboriginal Heritage Guidelines published under Part 2A. The agreement must be submitted for Ministerial approval; the Minister will test whether it “satisfactorily deals with” all known or potential heritage (s 19I(3)) and will have regard to prescribed matters in the regulations and guidelines.

If an authorisation is still required, ensure the draft contains the mandatory conditions prescribed by ss 21(2) and 23(3): immediate cessation within the prescribed distance, reporting, and a stand-down period. Management methodologies approved under s 20A(7) can provide an alternative pathway for known sites but must themselves demonstrate prior consultation and ongoing consultation triggers.

All persons on site must be briefed on stop-work and reporting protocols. Records of compliance with stand-down periods, reports made, and consultation undertaken should be maintained in real time. If a direction is received under s 24 or s 25, immediate compliance is required even if it appears to contradict an agreement; the direction prevails for its duration.

For landowners, the ongoing duty to report new discoveries survives sale; vendors must notify the Minister of any outstanding directions within 30 days (s 24(10)). Collectors must document reasonable protective measures taken in respect of objects in their possession.

Organisations should maintain a heritage management plan that maps the interaction between this Act, native title agreements, mining approvals and environmental impact statements. Training on the expanded inspector powers, including the new warrant and self-incrimination provisions commencing in 2025, is advisable. Finally, legal sign-off should confirm that any proposed defence under s 23(4) is supported by contemporaneous evidence of reasonable inquiries, not merely an assertion of ignorance.

By treating the Recognised Aboriginal Representative Body as a co-regulator rather than an external stakeholder, embedding stop-work protocols into contractual arrangements with contractors, and maintaining auditable records of every discovery and every decision not to treat a find as heritage, organisations can minimise both legal risk and the cultural harm the Act is designed to prevent.
