Roles and Responsibilities for Environmental Regulation
When a client asks, “Can we do this project?”, an environmental lawyer cannot begin with a yes or no. The first task is jurisdictional mapping: who has legal authority over the land, the actor, the activity and the environmental impact? In Australia the answer may involve Commonwealth, State and local government at the same time.
2.1 Why roles and responsibilities come before approval analysis
Environmental regulation in Australia is layered. A development may require local planning approval, State environmental authorisation and Commonwealth approval under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act). Those regimes do not become relevant merely because an activity is “environmental”. They become relevant because a Constitution, statute, regulation, planning instrument or delegation gives a particular government or decision-maker legal power.
This is why issue spotting in Environmental Law starts with more than the environmental harm. Suppose a corporation proposes a port, mine, subdivision, road, energy project or tourism development. The lawyer must identify: the site and tenure; the proponent; the activity; the environmental receptors; whether a Commonwealth place or Commonwealth agency is involved; whether a matter of national environmental significance (MNES) may be affected; which State statutes regulate the activity; which local planning instruments apply; and whether any law is inconsistent with another.
2.2 Australia’s federal structure
Australia is a federation. The Constitution distributes legislative power between the Commonwealth and the States. The starting point is the Commonwealth of Australia Constitution Act. The environmental-law significance is immediate: there is no single general Commonwealth “environment power”. Commonwealth environmental legislation therefore depends on one or more constitutional heads of power.
| Question | Legal source | Why it matters to environmental advice |
|---|---|---|
| What powers remain with the States? | Constitution ss 107–108 | States retain broad law-making capacity except where the Constitution gives exclusive power to the Commonwealth or another constitutional limitation applies. |
| What powers are exclusive to the Commonwealth? | Constitution ss 52 and 90 | Commonwealth places, parts of the Commonwealth public service and customs/excise can create distinct federal regulatory pathways. |
| What powers are shared? | Constitution s 51 | Many Commonwealth environmental laws are supported by concurrent heads of power such as trade and commerce, corporations and external affairs. |
| What if Commonwealth and State laws are inconsistent? | Constitution s 109 | The Commonwealth law prevails to the extent of inconsistency. The State law is not destroyed; it is inoperative to that extent while the inconsistency remains. |
2.3 Local government: powerful in practice, but not a third constitutional sovereign
Local government is not separately recognised as a law-making tier in the Australian Constitution. Its existence and powers derive from State legislation. In Queensland, relevant sources include the Local Government Act 2009 (Qld), the Planning Act 2016 (Qld), local planning instruments and, in some contexts, delegated or devolved functions under the Environmental Protection Act 1994 (Qld).
Historically councils were associated with “roads, rates and rubbish”. Modern environmental practice is much broader. Local planning schemes, development assessment, vegetation controls, stormwater, local laws and infrastructure decisions can make local government the first regulator a property developer encounters. The legal source remains State legislation, which means State law defines the extent of local power and State supervision.
2.4 Commonwealth places and Commonwealth immunity
Section 52(i) of the Constitution gives the Commonwealth exclusive power over places acquired by the Commonwealth for public purposes with State consent. Airports and defence facilities are classic environmental-law examples. State legislation may state that it binds the Crown or even the Commonwealth “so far as Parliament permits”, but that wording cannot expand State legislative power beyond constitutional limits.
The practical lesson is to identify tenure and legal status before assuming a State planning or environmental statute applies. Commonwealth legislation may expressly or impliedly displace State law, and s 109 may make an inconsistent State law inoperative. Conversely, Commonwealth legislation can adopt or apply State rules. Never advise from labels such as “airport land” alone; identify the legal interest, the federal statute and any express application or exclusion provisions.
2.5 Marine jurisdiction and the Offshore Constitutional Settlement
Marine regulation demonstrates how jurisdiction can be geographically divided. The Seas and Submerged Lands Act 1973 (Cth) asserted Commonwealth sovereignty over Australia’s territorial sea. The Offshore Constitutional Settlement later allocated title and legislative arrangements for coastal waters to the States and Northern Territory, supported by the Coastal Waters (State Title) Act 1980 (Cth) and Coastal Waters (State Powers) Act 1980 (Cth).
For a practitioner, the question is spatial: where exactly is the activity or impact? A project near the coast may cross local, State coastal-water and Commonwealth marine jurisdictions. Mapping is therefore legal analysis, not merely background geography.
2.6 There is no express Commonwealth “environment” power
Section 51 contains many express heads of Commonwealth legislative power, but “the environment” is not one of them. That does not mean the Commonwealth lacks environmental power. The High Court has interpreted several heads of power broadly enough to support laws with environmental objectives where the law can properly be characterised as a law with respect to the constitutional subject.
s 51(i) trade and commerce; s 51(xx) foreign, trading and financial corporations; s 51(xxix) external affairs; plus other powers including taxation, fisheries and quarantine in appropriate contexts.
2.7 Trade and commerce: Murphyores
Facts. Murphyores held Queensland leases to mine mineral sands on Fraser Island (K’gari). Export of the minerals required Commonwealth approval under customs legislation. The Commonwealth Minister deferred export approval pending inquiry into environmental effects.
Issue. Could a law supported by the trade and commerce power be administered by taking environmental considerations into account?
Principle. The High Court accepted that if the law is properly characterised as a law with respect to trade and commerce, environmental considerations do not make it constitutionally invalid merely because environmental protection is the practical objective.
Why it matters. Constitutional characterisation asks whether the law is sufficiently connected to a head of power, not whether environmental protection is the sole or dominant policy purpose. For advisers, this explains how Commonwealth control over exports and interstate/overseas trade can influence environmentally significant projects.
2.8 Section 92 and conservation: Cole v Whitfield
Tasmanian rules imposed minimum-size requirements for crayfish. The High Court held that s 92 prohibits discriminatory burdens of a protectionist kind. The Tasmanian rule burdened imported crayfish, but the same requirement applied to local crayfish and the conservation object could not effectively be achieved by regulating only locally caught stock.
Professional use. If a State environmental law affects interstate trade, do not assume s 92 invalidates it. Ask whether the burden is discriminatory in a protectionist sense and examine the law’s practical operation and legitimate non-protectionist purpose.
2.9 External affairs and the Tasmanian Dam Case
Facts. Tasmania supported construction of a hydro-electric dam in the Franklin/Gordon river system. The Commonwealth relied on legislation protecting World Heritage properties after Australia had ratified the World Heritage Convention.
Issue. Could the Commonwealth use the external affairs power in s 51(xxix) to implement international environmental obligations in an area otherwise falling within State responsibility?
Outcome and principle. A majority upheld key Commonwealth provisions. The case established the major practical significance of the external affairs power for environmental regulation and confirmed that treaty implementation can support Commonwealth legislation within constitutional limits.
Why it matters. When facts identify a World Heritage property, Ramsar wetland, migratory species or another international environmental obligation, the lawyer should connect the treaty dimension to the statutory provision implementing it. The treaty itself is not automatically self-executing domestically; the question is what Australian legislation gives it legal effect.
2.10 Corporations power
Section 51(xx) supports laws with respect to foreign corporations and trading or financial corporations formed within Australia. In the Tasmanian Dam litigation, the corporations power also supported provisions directed to the Hydro-Electric Commission as a trading corporation. For modern practice this matters because many environmentally significant actors are corporations: developers, miners, energy companies, banks and infrastructure operators.
The method is not “corporation = Commonwealth can regulate anything”. The lawyer must identify whether the entity falls within the constitutional category and whether the statutory provision is sufficiently connected to the corporation or its activities.
2.11 Cooperative federalism: why governments cooperate instead of litigating every overlap
Although s 109 provides a constitutional rule for inconsistency, environmental regulation cannot function efficiently if every overlap becomes a constitutional contest. Cooperative federalism describes arrangements through which Commonwealth, State, Territory and local-government interests are coordinated through agreements, accredited processes, national measures and shared programs.
The 1992 Intergovernmental Agreement on the Environment and the 1997 COAG Heads of Agreement helped shape a national division of responsibility and influenced the architecture later reflected in the EPBC Act. These agreements are important historically and institutionally even where they are not themselves directly enforceable as legislation.
2.12 Murray–Darling Basin: cooperative federalism under pressure
The Murray–Darling Basin crosses Queensland, New South Wales, Victoria, South Australia and the ACT. Water extraction, agriculture, communities and ecological health therefore cannot be managed coherently by one State acting alone. The Water Act 2007 (Cth) established a federal statutory framework including the Murray–Darling Basin Authority and the Basin Plan.
As at September 2026, implementation remains active. The Water Amendment (Restoring Our Rivers) Act 2023 extended key deadlines, including the 450 GL additional environmental-water target to December 2027. Current Commonwealth reporting in 2026 records ongoing water recovery and a 2026 Basin Plan Review. The teaching point is broader than one set of numbers: cooperative schemes evolve, so legal advisers must distinguish the statutory framework from current implementation policy and then verify both.
2.13 The EPBC Act: Australia’s principal Commonwealth environmental statute
The Environment Protection and Biodiversity Conservation Act 1999 (Cth) consolidates major elements of Commonwealth environmental regulation. The course uses the Act repeatedly because it provides a structured way to ask whether a proposed action engages nationally protected environmental matters.
Do not begin an EPBC problem by jumping to “approval”. Begin with the jurisdictional trigger. Identify the action, the protected matter, the impact and the controlling provision. The current authorised compilation must be checked because the EPBC framework has been amended over time.
2.14 Matters of National Environmental Significance (MNES)
The classic EPBC structure recognises nine categories of MNES. The Chapter 2 task is to learn what they are and how to locate the controlling provision; detailed assessment and approval procedure is developed later.
| MNES | Key EPBC Act references used in this chapter | Issue-spotting trigger |
|---|---|---|
| World Heritage values | ss 12, 15A | World Heritage property and significant impact on listed values. |
| National Heritage values | ss 15B, 15C; pt 15 heritage provisions | National Heritage List place such as the former High Court at 450 Little Bourke Street. |
| Ramsar wetlands | ss 16, 17B | Declared Ramsar wetland and potential impact on ecological character. |
| Listed threatened species and ecological communities | ss 18, 18A; s 178 species list | Habitat or population of a nationally listed threatened species/community. |
| Listed migratory species | ss 20, 20A; s 209 | Migratory fauna protected through international agreements. |
| Nuclear actions | ss 21–22 | Reactor, uranium mining/milling, spent fuel, specified radioactive-waste facilities. |
| Commonwealth marine area | ss 23–24A | Action in, or impacting, the Commonwealth marine environment. |
| Great Barrier Reef Marine Park | ss 24B–24C | Action in or affecting the Reef Marine Park environment. |
| Water resources — unconventional gas / large coal mining | ss 24D–24E | Large coal mining or unconventional gas action affecting a water resource. |
2.15 “Controlled action” thinking
The controlling provisions generally prohibit taking an action that has, will have or is likely to have a significant impact on the relevant protected matter unless an applicable approval, exemption or other statutory pathway exists. That means a lawyer must distinguish four questions:
- Is there an “action”?
- Is a protected matter engaged?
- Is the impact significant or likely significant under the relevant statutory framework?
- What procedural step follows before the action can lawfully proceed?
The Protected Matters Search Tool (PMST) is a useful due-diligence tool for identifying potential protected matters in or around a project area. It is indicative, not exhaustive. A PMST report is evidence-gathering, not a legal conclusion that referral is or is not required.
2.16 Commonwealth law does not automatically replace State and local law
A recurring client mistake is to ask, “If I get the federal approval, am I finished?” Usually not. Commonwealth, State and local requirements can operate concurrently. The EPBC framework contains mechanisms intended to reduce duplication, but federal environmental approval does not ordinarily erase separate planning, pollution, heritage, vegetation or licensing requirements imposed under State or local law.
2.17 From issue spotting to advice: four recurring client perspectives
| Client | First questions | Typical legal focus |
|---|---|---|
| Developer / corporation | What can stop or delay the project? What approvals are needed? What studies must be commissioned? | Jurisdiction, referrals, approvals, conditions, sequencing, due diligence, finance and enforcement risk. |
| Government / regulator | What power do we have? What process must we follow? What evidence supports the decision? | Statutory authority, mandatory considerations, procedural fairness, rationality, conditions and enforcement. |
| Community / environmental organisation | What protected matter or legal error exists? Who has standing? What remedy is available? | Standing, referral, review, injunction, judicial review, merits review where available and enforcement pathways. |
| Board / C-suite / financier | What is the material regulatory risk and what should happen before commitment of capital? | Approval certainty, timing, conditions, liabilities, disclosure, contractual allocation and project-governance controls. |
2.18 Chapter 2 synthesis
2.19 What the Week 3 tutorial adds to Chapter 2
The first hour of the Week 3 seminar returns to the Week 2 questions and shows how the Chapter 2 rules are actually used. The important lesson is methodological. An environmental lawyer does not answer an EPBC Act question by naming a species, opening a database and stopping at the search result. The lawyer moves from the facts to the statutory category, checks the legal source of the listing, identifies any geographic or population limitation, and then connects the result to the controlling provision and the client’s proposed action.
2.20 SPRAT is a research interface, not a substitute for the legal source
The tutorial uses the Species Profile and Threats (SPRAT) database to investigate threatened and migratory species. This is the practical tool students will repeatedly use, but the lecturer emphasised an important lawyer’s habit: the statutory lists and instruments are the primary legal source. SPRAT is the convenient interactive interface that helps you identify the listed species, category, distribution, listing history and recovery information.
The koala example demonstrates why. A search may show that the koala is listed as endangered, but the protected listing is geographically confined to the relevant populations in Queensland, New South Wales and the Australian Capital Territory. A lawyer advising about a project must therefore ask not only “Is the species listed?” but also “Is this population, subspecies or geographic occurrence within the legal listing?”
The same exercise distinguishes the Tasmanian devil, common kangaroos and wombats. The Tasmanian devil is listed as endangered. A generic search for “kangaroo” can produce misleading hits because the database contains many names incorporating that word; the ordinary kangaroo is not simply an MNES by reason of being iconic. The common wombat is not listed, while the northern hairy-nosed wombat is critically endangered. The tutorial also illustrates that threatened-species lists are dynamic: nominations are scientifically assessed and species can be added or moved between categories as their conservation status changes.
2.21 Migratory species: connect the database result to constitutional power
The whale question teaches students to work in both directions. A scientific-name search identifies the animal as a whale and SPRAT identifies its migratory status. The legal analysis then moves to the EPBC Act provisions for listed migratory species and the international agreement supporting the listing. The tutorial identifies the Bonn Convention as the relevant international source for the whale and links the Commonwealth’s legislative capacity back to the external affairs power in s 51(xxix) of the Constitution. The species does not need to be native to Australia before Commonwealth environmental protection can be supported by an international obligation.
2.22 Nuclear facilities problem: begin with application, then prohibition, definition, exception and constitutional escape routes
The nuclear PPP problem is a model of statutory navigation. Before jumping to the prohibition, the tutorial directs students to ask whether the Queensland Act purports to bind the relevant actor. Only then should the lawyer move to the operative prohibition, the definition of “nuclear facility”, and any express exception. The Week 2 question uses the Nuclear Facilities Prohibition Act 2007 (Qld).
APPLICATION → OPERATIVE PROHIBITION → DEFINED TERMS → EXCEPTIONS → CONSTITUTIONAL LIMIT → CONSEQUENCE → PRACTICAL SOLUTION.
The radioactive-waste facility must be analysed separately from the reactor. The tutorial identifies an exception for relevant medical-purpose radioactive waste, while the nuclear reactor remains within the type of facility the State legislation seeks to prohibit. The constitutional analysis then asks how the Commonwealth might lawfully proceed: enact valid inconsistent Commonwealth legislation so that s 109 operates; rely on an appropriate Commonwealth head of power; locate the project on a Commonwealth place where s 52 and Commonwealth immunity become relevant; or use a Commonwealth agency structure where legally appropriate.
The tutorial also highlights the distinction between law and politics. The Queensland legislation’s plebiscite mechanism is not itself a legally binding referendum capable of defeating valid Commonwealth law. Its function is political: it can demonstrate public opposition, influence Commonwealth politicians and affect the political feasibility of the project.
2.23 Heritage due diligence: the protected value matters more than the label
The former High Court redevelopment problem teaches a critical heritage-law point. Finding a site on the Australian Heritage Database or through the Protected Matters Search Tool does not end the analysis. For a National Heritage place, the lawyer must identify the National Heritage values for which the place is listed, obtain the official Statement of Values, and then ask whether the proposed action is likely to significantly impact those values.
That is why retaining a façade cannot automatically answer the question. If the protected values extend to the building’s historic form, setting, internal spaces or other architectural characteristics, an eight-storey addition at the rear may still affect the protected values. Conversely, listing does not mean that no development can ever occur. The professional task is to understand the legal values, redesign or mitigate where possible, and then determine whether the EPBC assessment and approval pathway is engaged.
2.24 PMST reports are desktop information: environmental due diligence requires ground-truthing
The Protected Matters Search Tool is designed to identify possible MNES in and around a site. The tutorial adds a crucial practice step: its output is based on available desktop information. It tells the lawyer what may be present, not necessarily what is actually present on the site at the relevant time.
Search areas also matter. Where a site is near a watercourse or another pathway through which impacts may travel, the tutorial recommends using an appropriate buffer rather than drawing the project boundary too narrowly. This links directly back to professional due diligence: the legal risk may extend beyond the cadastral boundary of the development site.
2.25 What Chapter 2 should now teach you to do
Identify the client and objective. Identify the land and tenure. Identify each level of government. Identify the constitutional source of Commonwealth power. Identify each potentially applicable Act. Start with application and definitions before operative provisions. Identify the MNES and its exact legal listing. Use official databases intelligently. Check geographic and population limitations. Distinguish desktop data from verified site conditions. Identify the controlling provision. Analyse Commonwealth-State inconsistency if it arises. Separate legal effect from political pressure. Then give the client a practical next step.

Chapter 2 Tutorial Model Answers
These answers incorporate the lecturer's first-hour Week 3 discussion of the Week 2 tutorial. They preserve the tutorial methodology: identify the precise statutory question, use official databases as research tools, confirm the legal source, and turn the result into practical advice.
Question 1 — Koala, Tasmanian devil, kangaroo and wombat
Issue. Which of the named species is protected as a matter of national environmental significance under the EPBC Act, and how should a lawyer determine that status?
Method and law. Begin with the threatened-species controlling provisions in Part 3, Division 1, Subdivision C, including s 18, and the statutory threatened-species list referred to in s 178. The tutorial then uses the SPRAT database as the practical research interface. SPRAT is reliable and routinely used in practice, but the statutory listing instrument remains the primary legal source.
Application. The koala is listed as endangered, but the listing is limited to the relevant populations in Queensland, New South Wales and the Australian Capital Territory. That limitation matters: a lawyer must read the listing scope and cannot assume that every koala everywhere in Australia attracts the same MNES protection. The Tasmanian devil is listed as endangered. A search for kangaroo produces many hits, including species and place names, but the ordinary kangaroo is not simply listed as an MNES. The common wombat is not listed, while the northern hairy-nosed wombat is critically endangered and occurs in very limited Queensland locations. The tutorial also discussed the southern hairy-nosed wombat as a nominated species, illustrating that the list evolves through scientific assessment.
Conclusion. The correct answer is not “iconic species = MNES”. The legal question is whether the precise species, subspecies or population is currently listed in a protected category and whether the client’s project affects that legally protected population.
Exam / practice lesson. Search the database, open the species profile, read the category and geographic limitation, then confirm the primary legal listing before advising.
Question 2 — Balaenoptera bonaerensis and migratory-species protection
Issue. On what basis can a whale species first described from a specimen found outside Australia nevertheless be a matter of national environmental significance under Australian law?
Rule. The EPBC Act protects listed migratory species. The tutorial directs students to s 209 and to the international agreements underlying migratory-species protection. A search of the scientific name identifies the species as a whale and SPRAT identifies it as migratory under the Bonn Convention.
Constitutional connection. The Commonwealth can rely on the external affairs power in s 51(xxix) of the Constitution to implement international environmental obligations. A protected migratory species therefore does not need to be native to Australia before Commonwealth legislation can validly protect it.
Conclusion. The whale is relevant as an MNES because it is a listed migratory species protected through the EPBC framework and the associated international convention.
Exam / practice lesson. Use the scientific name, identify the legal category, identify the treaty or agreement, and then connect that international source to the constitutional head of power.
Question 3 — Nuclear PPP in Queensland
Issue. Can the Queensland nuclear-facilities legislation prevent the Commonwealth’s proposed nuclear reactor and medical radioactive-waste facility, and what legal pathways may allow the project to proceed?
Statutory method. Do not begin with the prohibition alone. First check the Act’s application provision to identify whom it purports to bind. Then read s 7(1), the definition of “nuclear facility”, and the exceptions in s 7. The tutorial treats NML, the private corporate partner, as a “person” capable of being caught by the prohibition.
Application to the two facilities. The nuclear reactor falls within the type of facility the State Act seeks to prohibit. The radioactive-waste management facility must be analysed separately because the tutorial identifies an express exception for relevant waste arising from medical or research uses. That means the medical-waste facility may not be prohibited on the same basis as the reactor.
Commonwealth-State interaction. The State Act purports to bind the Commonwealth only to the extent Queensland legislative power permits. A lawyer must therefore move to the Constitution. Possible Commonwealth pathways discussed in the tutorial include: (1) enact valid Commonwealth legislation that is inconsistent with the Queensland law, engaging s 109; (2) rely on a valid Commonwealth head of power such as external affairs or corporations where the facts support it; (3) use a Commonwealth place, engaging s 52 and the principles of Commonwealth immunity; or (4) establish or use a Commonwealth agency where that structure is legally available.
Political dimension. The Queensland Act’s s 21 plebiscite mechanism is designed to obtain the views of Queensland voters where the Commonwealth proposes a prohibited nuclear facility. The tutorial emphasises that the plebiscite is not legally binding on the Commonwealth. Its force is political: it can influence voters, investors and Commonwealth decision-makers.
Conclusion. The medical-waste facility may fall within the statutory exception, while the reactor presents a direct State-law prohibition for ordinary actors. But the ultimate advice cannot stop at State legislation: Commonwealth constitutional power, immunity and any inconsistent federal legislation must be analysed before concluding that Queensland can legally prevent the Commonwealth project.
Question 4 — Former High Court, 450 Little Bourke Street
Issue. Does an urban redevelopment of the former High Court site potentially engage the EPBC Act, and what exactly must the lawyer investigate?
Method. Start with the site. Use the Australian Heritage Database and, where appropriate, the Protected Matters Search Tool. The tutorial identifies the property as a National Heritage place. The critical legal question is not merely whether the building is listed, but which National Heritage values are protected.
Rule. For National Heritage, the controlling analysis focuses on the protected National Heritage values, including the framework reflected in s 15B. The official listing and Statement of Values explain why the place is protected and therefore what characteristics a development must avoid significantly impacting.
Application. Retaining the ground-level façade is relevant but is not automatically sufficient. The eight-storey serviced-apartment addition must be tested against the listed architectural and historic values, including the visual form, setting and any protected internal or contextual features. A project can be redesigned or conditioned to reduce impact; listing does not mean that all development is automatically forbidden.
Conclusion. The EPBC Act is potentially relevant. JurisPrudent should obtain the formal listing material and Statement of Values, map the proposed works against those values, and assess whether design changes, mitigation, referral or later approval processes are required before committing to the redevelopment.
Question 5 — Murray–Darling Basin Plan
Issue. What does the current Basin Plan process illustrate about cooperative federalism?
Answer. The Basin spans Queensland, New South Wales, Victoria, South Australia and the ACT, so its management requires coordination across political boundaries. The tutorial uses it as an example of the difficulty of cooperative federalism: competing water demands, environmental objectives and State interests have made implementation contentious and expensive. The seminar discussion described the existing arrangements as having performed less effectively than intended and referred to the significant public cost of the reform program.
The class discussion also noted that a long-term monitoring and review process is continuing, that consultation on the review had concluded, and that a further draft Basin Plan was expected as the review process advanced. Because this is a changing policy and statutory implementation area, students should use the Water Act 2007, the current Basin Plan and current Commonwealth/Murray-Darling Basin Authority material rather than relying on an old tutorial statement of status.
Professional lesson. Distinguish the permanent legal architecture from changing implementation milestones. Cooperative federalism is a legal and institutional structure, but its success depends on continuing intergovernmental cooperation, funding, water recovery and implementation.
Question 6 — Protected Matters Search Tool and ground-truthing
Issue. What does a PMST report tell a lawyer, and what must happen after the desktop search?
Rule / method. The Protected Matters Search Tool identifies potential MNES in or near a defined area and generates a desktop report. The search boundary should be chosen sensibly. Where impacts can move beyond the site—for example through a watercourse—the tutorial recommends using an appropriate buffer rather than drawing the search polygon too tightly.
Limitation. The report is based on existing government-held information about where protected matters have been recorded, modelled or are thought to occur. It does not prove that the matter is physically present on the project site and it does not itself determine whether an impact will be significant.
Next step. Where the desktop result identifies a material risk, the project team may need ground-truthing: appropriately qualified experts inspect the site and test whether the relevant habitat, species, ecological community, wetland, heritage value or other matter is actually present and how the proposed activity would affect it.
Conclusion. PMST is an essential first-pass due-diligence tool, not the end of the legal inquiry. The lawyer uses the report to identify what expert evidence is required and then applies the verified facts to the controlling EPBC provisions.
Chapter 2 IRAC Problem Questions
A Queensland corporation proposes a port expansion partly within State coastal waters and with dredging effects extending into the Commonwealth marine area. Migratory shorebird habitat is nearby. State development approval is likely. Advise the board what jurisdictional questions must be resolved before works commence.
A State prohibits possession of undersized shellfish regardless of whether the shellfish were caught locally or imported from another State. An interstate trader argues the law breaches s 92. Advise.
A State-owned corporation proposes infrastructure within a World Heritage property. The State argues the project is entirely intrastate and therefore outside Commonwealth power. Advise on the constitutional and EPBC issues that should be investigated.
Chapter 2 Detailed IRAC Model Answers
IRAC 1 — Port expansion and overlapping governments
Issue. Whether State approval alone authorises the port works and what Commonwealth environmental triggers may apply.
Rule. State/local approvals can coexist with Commonwealth EPBC requirements. Potential Commonwealth triggers include listed migratory species and impacts on the Commonwealth marine area. The exact controlling provisions must be checked in the current EPBC Act. Marine jurisdiction also requires spatial identification of coastal waters and Commonwealth waters.
Application. The corporation should map the dredge footprint, plume and ecological effects; identify migratory species and habitat; obtain a PMST report and targeted ecology; determine whether impacts extend to the Commonwealth marine environment; and analyse significant impact under each relevant controlling provision. State approval should be tracked separately in an approvals matrix. Contract and construction programs should prevent physical works until all conditions precedent are satisfied.
Counterargument. The proponent may argue impacts are minor, temporary or adequately mitigated. That argument requires evidence; it cannot be assumed from the existence of State approval.
Conclusion. State approval is not enough to advise that works may begin. Commonwealth screening/referral advice and evidence should be completed first.
IRAC 2 — State conservation law and interstate trade
Issue. Whether the State shellfish law imposes a constitutionally prohibited burden on interstate trade.
Rule. Section 92 prohibits discriminatory burdens of a protectionist kind. Cole v Whitfield upheld a materially similar minimum-size conservation rule because it applied to local and imported crayfish and was not protectionist in character.
Application. The law applies the same size rule irrespective of origin. If the conservation objective cannot practically be achieved by regulating only locally caught stock, the burden on interstate traders does not by itself establish protectionist discrimination.
Counterargument. Evidence of practical discrimination or a disguised economic preference for local traders could alter the analysis.
Conclusion. On the stated facts, the law is likely consistent with the Cole v Whitfield approach and not invalid merely because it burdens interstate trade.
IRAC 3 — World Heritage project
Issue. Whether the Commonwealth can regulate an intrastate State-corporation project affecting World Heritage values.
Rule. Section 51(xxix) external affairs supports Commonwealth implementation of international obligations; Commonwealth v Tasmania is the central authority. The corporations power may also be relevant depending on the legal character of the State-owned corporation. The EPBC Act contains controlling provisions for significant impacts on World Heritage values.
Application. The fact that construction occurs wholly within one State does not resolve Commonwealth power. The lawyer should identify the World Heritage listing and protected values, the international obligation implemented by federal law, the status/activities of the State corporation, and the project’s likely impacts. State authorisation does not displace a valid federal prohibition or approval requirement.
Counterargument. The State may contest whether the federal statutory provision is engaged on the facts or whether the impact is significant, but a bare “intrastate project” argument does not answer the constitutional authorities.
Conclusion. There is a substantial Commonwealth constitutional and EPBC pathway requiring investigation before the State-owned corporation proceeds.
