Start with meaning before machinery. Week 1 asks why environmental law exists, what the word environment means in a particular statute, and how competing anthropocentric, biocentric and ecocentric values influence - but never replace - legal analysis. A decision-maker acts within statutory power, not personal preference.

The interpretation sequence

Definitions are legal triggers

The current Environmental Protection Act 1994 (Qld) s 8 is deliberately broad: it reaches ecosystems and their constituent parts; natural and physical resources; qualities and characteristics of locations, places and areas; the physical surroundings in which people live; and social, economic, aesthetic and cultural conditions affecting, or affected by, those matters. The exam lesson is not to memorise a philosophical label. It is to read the statutory words and ask which factual feature fits which limb.

The Crown v Murphy - Mon Repos

Why it matters. The High Court example is not a slogan that “turtles are the environment”. Its value is contextual. Where legislation uses “environment” without an exhaustive definition, surrounding ecological conditions and the use of neighbouring land by turtles may form part of the environment of the land under consideration. A change in turtle use or hatchling survival may therefore be legally relevant because it changes the surrounding environmental conditions.

Sierra Club v Morton and Christopher Stone

Why it matters. The United States standing case illustrates the difference between human standing rules and the idea that natural objects might be represented through guardians. Justice Douglas' dissent and Stone's “Should Trees Have Standing?” are persuasive/philosophical materials, not binding Australian standing law. Use them to explain the evolution of environmental values and representation, not as an Australian rule of standing.

Orogen / Taylors Beach professional lesson

The Taylors Beach clearing prosecution is a practical warning. Environmental consultants, planners and project managers can create serious exposure when mapping, approvals, conditions or ecological constraints are misunderstood. The lawyer's task is to convert environmental information into a compliance system: identify the prohibition, permit/approval pathway, site constraints, who is responsible, what evidence is relied on and what must not occur.

First question: who can legislate? There is no general Commonwealth “environment” head of power. Commonwealth environmental law is supported by enumerated constitutional powers. States retain broad residual legislative power, while Commonwealth and State laws may operate concurrently unless valid Commonwealth law is inconsistent with State law.

Constitutional map

s 51(i) trade and commerce; s 51(xx) foreign, trading and financial corporations; s 51(xxix) external affairs; s 51(ii) taxation; s 52(i) exclusive Commonwealth power over Commonwealth places; s 90 exclusive customs/excise; s 92 interstate trade and commerce freedom; s 109 Commonwealth law prevails to the extent of inconsistency. Sections 107-108 preserve State constitutional powers and laws subject to the Constitution.

Murphyores and O'Sullivan

Murphyores Inc Pty Ltd v Commonwealth shows that a law validly characterised as a trade-and-commerce law can be administered with environmental considerations in mind. O'Sullivan v Noarlunga Meat Ltd shows that the trade-and-commerce power can extend into antecedent production activity where regulation is sufficiently connected with export/interstate trade.

Commonwealth v Tasmania - the Tasmanian Dam Case

The proposed Franklin River dam engaged the World Heritage Properties Conservation Act 1983 (Cth), enacted after Australia ratified the World Heritage Convention. The High Court upheld the Commonwealth legislation. The case establishes the breadth of s 51(xxix): implementation of a bona fide treaty obligation can support Commonwealth legislation even where the regulated subject matter would otherwise fall within State land/resource responsibility. The corporations power also mattered because the Hydro-Electric Commission was a trading corporation for relevant purposes.

Richardson v Forestry Commission

Richardson confirms the expansive external-affairs approach. It is important when the Commonwealth acts protectively before the final international status of a site is settled: the constitutional inquiry is whether the legislation is sufficiently connected to an external affair/treaty implementation, not whether the State agrees with the environmental policy.

Cole v Whitfield

Tasmania's minimum crayfish-size rule burdened interstate trade but was not protectionist because it applied equally to local and imported crayfish and pursued conservation. The case teaches that s 92 invalidity turns on discriminatory protectionism, not the mere fact that environmental regulation burdens interstate trade.

Under the current authorised EPBC Act compilation (Compilation No 70, 24 August 2026), Part 3 is the statutory map. The “matter” must be matched to the exact controlling provision; the protected value must then be matched to the evidence.

Part 3 Division 1 - MNES

World Heritage: ss 12-15A. National Heritage: ss 15B-15C. Ramsar wetlands: ss 16-17B. Listed threatened species/ecological communities: ss 18-19, with listing machinery including ss 178-182. Listed migratory species: ss 20-20B, with s 209 listing. Nuclear actions: ss 21-22A. Commonwealth marine area: ss 23-24A. Great Barrier Reef Marine Park: ss 24B-24C. Water resources for unconventional gas/large coal mining: ss 24D-24E. Additional prescribed MNES: s 25.

Other protected matters

Part 3 Division 2 separately protects the environment from actions involving Commonwealth land and Commonwealth agencies: ss 26-28AB. Do not confuse those Commonwealth-environment triggers with the nine MNES categories.

Source hierarchy

Treaties/conventions are binding internationally after the relevant steps of signature/ratification but are not generally self-executing domestically in Australia. Declarations such as the Rio Declaration are soft law: influential, capable of shaping statutes and policy, but not automatically enforceable domestic rules. Customary international law requires sufficiently general and consistent State practice plus opinio juris.

Permanent sovereignty + no-harm

Sovereignty gives a State legal authority over its territory and resources, but it is not a licence to export serious environmental injury. Trail Smelter is the classic transboundary-pollution authority: Canada was responsible for serious cross-border damage caused by fumes from the Trail smelter. The professional lesson is to identify both the territorial right and the cross-border duty.

Pulp Mills

In Pulp Mills on the River Uruguay, the ICJ treated environmental impact assessment as having become a requirement of general international law where a proposed industrial activity risks significant adverse transboundary impact, while leaving the specific content of EIA primarily to domestic law/authorisation processes. This links Week 3 directly to Week 4: EIA is both an international due-diligence idea and a domestic statutory procedure.

Precautionary principle - Leatch

The principle responds to a particular combination: a threat of serious or irreversible environmental damage plus scientific uncertainty. In Leatch, uncertainty about the giant burrowing frog did not justify pretending there was no risk. Stein J treated precaution as common-sense environmental decision-making. The result was refusal of the fauna licence on the evidence then available, while leaving open the possibility that better information or project changes could justify a different future result.

Intergenerational equity - Gray and Taralga

Gray v Minister for Planning demonstrates that environmental assessment can require consideration of cumulative/downstream greenhouse consequences where statutory objects require ESD. The decision was invalid because the assessment process failed to grapple adequately with those consequences. Taralga Landscape Guardians shows the other side: intergenerational equity can support approval where long-term public environmental benefits outweigh local landscape impacts. ESD is therefore a structured decision principle, not an automatic veto.

Myers v South Gippsland Shire Council

A coastal subdivision faced evidence of future inundation and loss of access. VCAT adopted a precautionary, long-term planning approach and refused the development. The owners' willingness to accept the risk was not enough because planning decisions externalise risk to future owners, public authorities and future generations.

Climate

The UNFCCC, Kyoto Protocol and Paris Agreement form the international climate framework discussed in Week 3. Domestically, the current Commonwealth framework includes the Climate Change Act 2022 (Cth). The legal method is always: treaty obligation/policy -> constitutional power -> domestic statute -> decision criterion. Do not treat international targets as if they were self-executing development controls.

Marine pollution

International oil-pollution, ship-pollution and hazardous-waste treaties are implemented through Commonwealth statutes including the various Protection of the Sea Acts and the Environment Protection (Sea Dumping) Act 1981 (Cth). Identify the particular pollution source, vessel/activity, convention and implementing statute before advising.

Biodiversity and CITES

The Convention on Biological Diversity links protected areas, threatened-species regulation and impact control. CITES is reflected in EPBC Act Part 13A, which regulates international movement of wildlife and wildlife products.

Humane Society International v Kyodo Senpaku

The whaling litigation demonstrates the difference between legal jurisdiction and practical enforcement. HSI relied on EPBC Act whale-sanctuary provisions against a Japanese whaling company. The Full Court rejected the idea that diplomatic sensitivity alone should deny access to the Australian court; an injunction was ultimately granted. Yet enforcement remained practically difficult while vessels stayed outside Australian control. Remedy analysis must therefore distinguish what the court can order from how effectively the order can be enforced.

EIA is a legal decision system, not just an environmental report. Learn the sequence: SCREENING -> SCOPING -> IMPACT ANALYSIS -> MITIGATION/ALTERNATIVES -> REPORT -> PUBLIC REVIEW -> DECISION -> CONDITIONS -> FOLLOW-UP/COMPLIANCE. The earlier EIA begins, the greater the ability to redesign rather than remediate.

Controlled-action logic

Section 67 defines a controlled action by reference to the Part 3 controlling provisions. Section 67A prohibits taking a controlled action without the required legal basis. The lawyer must therefore identify (1) the proposed “action”, (2) the protected matter/value, (3) the relevant Part 3 provision, (4) the impact pathway, and (5) whether the impact is significant or likely significant.

Likely + significant + impact

Booth v Bosworth supports a real/not-remote possibility approach to “likely”; Jarasius v Forestry Commission of NSW is used in the teaching for the same “real or not remote” formulation. “Significant” means important, notable or of consequence. The current Significant Impact Guidelines are practical guidance, but the statutory words and controlling provision remain primary.

Who refers?

s 68(1): a person who thinks the proposed action may be or is controlled must refer. s 68(2): even a person who thinks it is not controlled may refer for certainty. s 68(3): the referral must state the proponent's view. s 68(4): if the proponent says it is controlled, identify each proposed controlling provision. s 68(5)-(6): read with prior referral and s 68A contract/arrangement rules. ss 69-71 allow State/Territory, ministerial-request and Commonwealth-agency pathways.

What must the referral contain?

s 72(1)-(2): prescribed form/method and prescribed information. s 72(3): alternatives may address location, timing and activities. s 73: information to the proponent where another body referred. s 74: consultation/information process, including public participation. The Week 4 teaching emphasises that referral candour is a legal risk issue, not an administrative nicety.

Piecemeal / early works

s 74A allows the Minister to refuse a component referral and require the larger action to be referred where appropriate. s 74AA creates offence exposure for taking the referred action (or relevant larger action) before the referral decision process is complete, subject to statutory exceptions. s 489 separately addresses false or misleading information supplied to obtain approval/permit.

Section 75 decision

s 75(1) requires the Minister to decide whether the referred action is controlled and which Part 3 provisions control it. s 75(1A) brings public comments into the decision. s 75(2) directs attention to adverse impacts and excludes beneficial impacts at this screening stage. s 76 enables further information. s 77 requires notice/reasons machinery. s 77A governs “not controlled action - particular manner”, which operates like a binding project-description constraint.

Clearly unacceptable

ss 74B-74D create the early clearly-unacceptable pathway. The Asian Renewable Energy Hub/80 Mile Beach example demonstrates why a project with strong renewable-energy benefits can still fail where the protected-matter impact is unacceptable. Broader project merit does not erase a threshold statutory protection.

Reconsideration and variation

s 78 permits ministerial reconsideration in specified circumstances; ss 78A-79E provide request/comment/outcome machinery. ss 156A-156E govern requests to vary the proposed action during the approval process. s 158A protects approval-process decisions from being destabilised merely because a relevant listing event occurs after the s 75 decision, subject to the statutory scheme.

Nathan Dam

A dam proposed to supply irrigation water could lead to downstream cotton expansion and pesticide runoff reaching Great Barrier Reef values. The Full Federal Court rejected an artificially narrow “direct impact only” approach. Consequences of third-party conduct can be impacts where sufficiently connected to the referred action. Parliament later inserted s 527E, so the modern answer is: teach the case for principle/history, then apply the current statutory definition.

Mees v Roads Corporation

The Scoresby Freeway referral was challenged because the information supplied could be misleading by omission even without a literal false statement. The professional lesson is full project disclosure. If the component is commercially/physically part of a larger committed project, artificial slicing can trigger s 74A and credibility/judicial-review risk.

Brown v Forestry Tasmania (No 4)

The first-instance decision treated the RFA exemption as unavailable where required threatened-species protections had not effectively been delivered. The Full Court later allowed Forestry Tasmania's appeal. The exam lesson is essential: always check appellate history before stating a “rule”. Use the litigation to understand how statutory exemptions operate, but cite the final appellate position accurately.

Q1 - what should be referred?

Separate the actors: RUD; Queensland Government/TMR; Gold Coast City Council. Separate the actions: resort; 9 km access road; State connector road through Gondwana Rainforests; Council dam; associated changes in irrigation/pesticide pathways. Then test each action/larger action against each potentially affected protected matter. World Heritage values, listed threatened species/ecological communities, migratory species and other applicable Part 3 matters must be analysed by exact controlling provision. The fact that an action is undertaken by a different legal person does not end the inquiry into indirect consequences of the primary action; use s 527E and Nathan Dam.

Counterargument: RUD can argue that the State road and Council dam are independent government projects. The response depends on evidence: legal control is relevant but not conclusive; ask whether RUD's project facilitates them, whether they are committed/foreseeable consequences and whether the actions should be separately referred by their own proponents.

Q2 - coordinated project / Queensland EIS

A declaration under Part 4 of the State Development and Public Works Organisation Act 1971 (Qld) does not itself switch off Commonwealth law. State and Commonwealth assessment can be coordinated through accredited/bilateral arrangements where the statutory requirements are satisfied, but assessment substitution is not the same thing as Commonwealth approval disappearing. The politicians' “avoid Commonwealth interference” statement is legally overbroad.

Q3 - precautionary principle challenge

Start with the EPBC statutory setting, not the abstract Rio formulation. Section 391 requires the precautionary principle to be taken into account in specified decisions under the Act. Identify whether the Minister's approval decision is one of those decisions and whether the factual trigger exists: threat of serious/irreversible damage plus lack of full scientific certainty. The uncertain transfer of the Oxleyan Pygmy Perch, unique evolutionary significance and breeding-habitat disruption are evidence to analyse, not automatic proof of invalidity.

Counterargument: RUD may point to mitigation, translocation precedent and expert management. David's argument is strongest if the Minister ignored the statutory principle or treated uncertainty as a reason to assume no harm. It is weaker if the Minister genuinely considered the principle and lawfully balanced it within the statutory decision framework. Judicial review targets legality of the reasoning process, not a court re-making environmental merits.

Q4 - conditions, bond and contribution

Before final approval, s 131AA gives the proponent an opportunity to comment on the proposed approval/conditions. s 134 is the central condition power and requires the statutory nexus; s 136 governs relevant considerations. Analyse the $10 million rehabilitation bond by asking whether it secures compliance/rehabilitation connected to protected matters and the approved action. Analyse the mangrove-scheme contribution separately: a general environmental benefit is not enough if the condition lacks the required statutory connection.

A conclusion is not the end of a legal answer

After reaching the legal conclusion, ask what happens next. Environmental law remedies are often public-law/regulatory rather than ordinary compensatory damages. Depending on the statute and cause of action, consequences can include refusal of approval, mandatory conditions, injunction, civil penalty, criminal prosecution, remediation/rehabilitation, suspension/revocation, reconsideration, judicial review, merits review where legislation provides it, or a negotiated redesign/undertaking.

Four remedy questions

1. Prevention: can unlawful works be restrained before damage occurs? Under the EPBC Act, s 475 provides an injunction framework. 2. Regulatory consequence: is there a civil penalty/offence, condition, stop-work or approval consequence? 3. Decision challenge: is the complaint jurisdictional/legal (judicial review) or merits-based, and is merits review actually available? 4. Private loss: is there a separate common-law/statutory claim for loss or damage? Do not assume “damages” is available merely because environmental harm occurred.

Professional advice format

Immediate: stop irreversible/high-risk activity and preserve evidence. Investigate: exact Act, protected matter, approvals, conditions, maps, expert evidence. Analyse: elements + cases + counterarguments. Decide: refer/apply/redesign/negotiate/challenge. Document: who decided what and on what evidence. Monitor: conditions, new information, listing changes and compliance obligations.

Open-book navigation

Tab the Constitution; statutory interpretation; EPBC Part 3 controlling provisions; listing provisions; action/impact definitions; ss 67-79E referral/screening; s 391 precaution; ss 131AA/134/136 conditions; s 475 injunctions; cases by proposition; treaties by domestic connection; tutorials by issue. The Week 4 seminar expressly warns that open book does not mean unlimited time: organisation is part of performance.

Verification rule

For examination and publication, use the lecturer's teaching to identify what matters, then verify the legal proposition against the authorised legislation/current instrument and the judgment. Transcript errors such as phonetic case names or outdated agency labels must not be repeated as law. The EPBC Act used here is the authorised Compilation No 70, in force from 24 August 2026; uncommenced future-law amendments are not treated as current law.
