Who enforces and how: the Attorney‑General or an "interested person" may seek injunctions in the High Court or the Federal Court to stop unlawful acts (section 14). The Act defines who counts as an "interested person" for enforcement and for judicial review standing (sections 14(3) and 13(5)). Ministerial decisions are subject to judicial review processes (Administrative Decisions (Judicial Review) Act references in section 13).

Parliamentary oversight of proclamations: Proclamations must be laid before each House of Parliament within five sitting days (section 15). If not laid, or if either House passes a disallowing resolution within the specified time, the Proclamation ceases to be in force (section 15(2)–(4)). Revocations by the Governor‑General also require resolutions of both Houses before being made (section 16(3)).

Compensation and acquisition rules: where the operation of the Act (or the referenced World Heritage (Western Tasmania Wilderness) Regulations) results in an acquisition of property, the Act provides a multi‑step compensation process. A person may claim compensation (section 17(3)); the Minister can deny the claim within 3 weeks (section 17(4)); failing that, an acquisition is taken to have occurred (section 17(5)). For large claims (claimed amount ≥ $5,000,000) and unresolved cases, the Governor‑General must establish a three‑member Commission of Inquiry to recommend compensation; the Governor‑General then determines compensation if parties do not agree (sections 17(6)–(12)). For smaller claims, the Federal Court may determine fair and just compensation (section 17(14)). The Act allows flexible forms of compensation (section 17(2)).

Special rules for Aboriginal sites: the Act declares sections 11 and specified subsections to be special laws for the Aboriginal race (section 8(1)). The Governor‑General can proclaim Aboriginal sites for special protection where artefacts or relics or the site are of particular significance to Aboriginal people (section 8(2)–(3)). Members of the Aboriginal race have specific standing as "persons aggrieved" for review of Ministerial decisions under section 11 (section 13(7)) and as "interested persons" for injunctions under section 14 (section 14(5)).

Scope and exceptions: the Act does not override existing federal protections such as zoning under the Great Barrier Reef Marine Park Act or management plans under the National Parks and Wildlife Conservation Act when those plans authorize the acts in question (section 12(1)). Regulations may also declare State or Territory provisions, plans or schemes to be acceptable authorisations so the Act’s prohibitions do not apply to acts authorised under those instruments (section 12(2)–(3)). The Governor‑General may make regulations to declare property to be part of the cultural or natural heritage and to prescribe assistance methods to States and Territories (section 21).

Practical compliance effects and incentives (source‑grounded):

• Persons (including their servants and agents) and certain corporations (foreign corporations, Territory corporations, and trading corporations formed in the Commonwealth) must obtain written Ministerial consent before carrying out excavation, mining, major construction, tree felling, road building, use of explosives, or other prescribed acts on proclaimed identified property or proclaimed Aboriginal sites; failing to obtain consent makes those acts unlawful (sections 9–11 and 10 for corporations). This imposes an administrative compliance burden on landholders, developers, miners and corporate operators who wish to use or develop proclaimed land.
• The Minister’s consent is constrained for decisions under section 9: the Minister must have regard only to "protection, conservation and presentation" within the Convention meaning (section 13(1)). That is the statutory decision criterion; other public policy objectives are not authorised grounds for consent decisions under that subsection.
• The Minister must inform and allow representations from the relevant State/Territory counterpart before consenting for land in a State/Territory (section 13(3)), creating an intergovernmental consultation step.
• Corporations used for trading activities face a specific bar on doing specified acts for the purposes of their trading activities unless the Minister consents (section 10(4)), which directly constrains commercial exploitation of resources or development on proclaimed land by such corporations.
• Where the operation of the Act results in an effective acquisition of property, the Commonwealth is liable to compensate the affected person; major claims trigger a formal Commission of Inquiry process with a statutory timetable (section 17).

Trade‑offs, opportunity costs and implementation risks (source‑grounded):

• Trade‑off: the Act prioritises heritage protection mechanisms (consent prohibitions and criminality) over unfettered private land use on proclaimed properties (sections 9–11). Those restrictions reduce the range of private actions available without approval and may require compensation where an acquisition occurs (section 17).
• Opportunity cost and concentrated vs diffuse effects: the measures concentrate compliance costs on property owners, operators and corporations active on specific proclaimed sites (sections 9–11, 10), while the asserted benefit (heritage protection and Australia's international obligations under the Convention) is diffused; the statute builds a compensation pathway for persons who claim an acquisition resulted (section 17).
• Implementation risk and administrative discretion: the system depends on executive instruments—Proclamations (sections 6–8), Ministerial consents (sections 9–11, 13), regulatory declarations (section 21), and possible delegation (section 18). The Minister has operational discretion in granting consents (with the statutory constraint in section 13(1) for section 9 matters), and the Governor‑General makes declarations and revocations with parliamentary involvement (sections 6, 15, 16). The Act provides judicial remedies (injunctions, judicial review) that can restrain acts or review decisions (sections 14 and 13(5), (7)).

Administrative burden and legal risk for private actors: affected private persons and corporations must (a) check whether property is proclaimed (Proclamations are published in the Gazette and laid before Parliament—section 3(3); sections 15 and 13(4)); (b) obtain written Ministerial consent for many common development/mineral activities (sections 9–11); and (c) use statutory review and court remedies if adversely affected (sections 13, 14). Transactions involving proclaimed land may involve compensation claims and, for large claims, a formal Commission of Inquiry with statutory deadlines (section 17).

Summary of the statute’s institutional architecture in one sentence: the Act gives the Commonwealth a statutory route (Proclamation by the Governor‑General and Ministerial consents) to restrict and, where necessary, prevent damaging acts on World Heritage–related property and Aboriginal sites, establishes administrative and parliamentary safeguards for those executive actions, and sets out compensation and judicial review procedures where the Act’s operation affects property rights (sections 3, 6–13, 14, 15–17).
