Constitutional Powers (Coastal Waters) Act 1980

The instrument rests on a few conceptually distinct moves, each expressed in the Schedule text. The Schedule’s key concepts are: coastal waters of a State, adjacent area, the extent of the territorial sea, the extension of State legislative power, and savings preserving Commonwealth authority and international law duties.

Definitions and cross-references. The Schedule defines adjacent area with direct reference to Schedule 2 to the Petroleum (Submerged Lands) Act 1967, as that instrument stood immediately before commencement (s 3(1)). That means the spatial reach used for many operative provisions is not a self-contained definition inside the Act, but a cross-reference to an identified schedule in another Commonwealth statute as in force immediately before commencement. The Acts Interpretation Act 1901, as in force immediately before the day of Royal Assent, applies to the interpretation of the Schedule (s 3(2)). Those two cross-references import external statutory frameworks into the Act’s interpretive lattice.

Coastal waters. The Schedule’s definition of coastal waters of the State comprises: (a) the part(s) of the territorial sea within the adjacent area (excluding any part referred to in s 4(2)), and (b) any sea on the landward side of any part of the territorial sea within the adjacent area that is not within State or Territory limits (s 3(1), Schedule). That definition links the State’s coastal waters to the Commonwealth-determined limits of the territorial sea (s 4(1)) and conditions the spatial reach on the adjacent area mapping from the Petroleum Act.

Territorial sea limits and qualification. Section 4(1) fixes the limits of the territorial sea for purposes of the Act to those ascertained consistently with the Seas and Submerged Lands Act 1973 and instruments under it and any agreement with another country regarding outer limits. Section 4(2) then qualifies coastal waters coverage: if the territorial sea breadth is determined to be greater than three nautical miles, references to coastal waters in the Act do not include any part that would not be within limits if the breadth had stayed at three nautical miles. The combined effect is to tie the Act’s geographic reach to Commonwealth determinations but to carve out an upper bound for State coastal waters in particular circumstances.

Extension of State legislative powers. Section 5 is the operational heart. It provides that the legislative powers exercisable under the constitution of each State extend to making laws as if the coastal waters were within the State limits, including laws applying to the sea-bed, subsoil and airspace above coastal waters (s 5(a)). It also authorises State laws to apply to waters within the adjacent area beyond coastal waters for specific subject-matter matters: subterranean mining from State land and ports, harbours and other shipping facilities and coastal works including installations and dredging (s 5(b)). Finally, s 5(c) permits State laws to apply to fisheries beyond the coastal waters where management arrangements between the Commonwealth and the State provide for that.

Savings and international law. Section 6 preserves the international status of the territorial sea and the Commonwealth’s role in ensuring observance of international law, explicitly identifying the Convention on the Territorial Sea and the Contiguous Zone’s right of innocent passage as an example. Section 7 saves against the Act being read to extend State boundaries (s 7(a)), or to derogate from other extraterritorial legislative powers a State might have (s 7(b)). Crucially, s 7(c) provides that nothing in the Act gives force to a State law to the extent it is inconsistent with a law of the Commonwealth or with the Commonwealth Constitution.

Procedural/constitutional provenance. The Preamble repeatedly identifies paragraph (xxxviii.) of s 51 of the Commonwealth Constitution as the constitutional mechanism by which State Parliaments can request the Commonwealth to legislate to extend State powers beyond their territorial limits; the Victorian Act is itself the vehicle for that request (Preamble and s 2). The Schedule is the text the State requests the Commonwealth enact.

These concepts together create a structure whereby States, through Commonwealth legislation enacted at their request, can be vested with law-making competence over specified parts of coastal and adjacent marine areas and certain subject matters in the adjacent area, while preserving Commonwealth international obligations and primacy where inconsistency arises.

The Act directly implicates three institutional categories set out in the text, and it affects particular private and commercial activities through the legislative powers it confers.

Primary institutional actors named in the text. The Commonwealth Parliament is directly implicated because the State (Victoria) is formally requesting it to enact the Schedule’s model statute (s 2 and the Preamble). Each State Parliament is implicated: the Schedule operates to extend the legislative powers exercisable under the constitution of each State (s 5). The Commonwealth executive and agencies are implicated indirectly because s 4(1) ties territorial sea limits to the Seas and Submerged Lands Act 1973 and instruments made under that Act, and because s 6 expressly preserves Commonwealth duties to ensure observance of international law, including rights of innocent passage.

Private and commercial actors affected through subject-matter expansions. The Schedule’s s 5(a) brings the sea-bed, subsoil and airspace above the coastal waters within the prospective scope of State legislation. That directly affects entities engaged in activities that use those strata, for example those with interests in seabed resource exploration or exploitation, infrastructure projects on the seabed, or activities affecting airspace above coastal waters, because State law may be made regulating such activities. Section 5(b)(i) extends State regulatory reach to subterranean mining from land within State limits in waters within the adjacent area beyond the coastal waters; that affects land-based mining operators whose operations intersect submerged strata offshore within the adjacent area as defined. Section 5(b)(ii) extends State law to ports, harbours and other shipping facilities, installations and dredging and other coastal works beyond coastal waters but within the adjacent area: that directly touches port authorities, harbour operators, shipping companies, dredging contractors and owners of coastal installations. Section 5(c) addresses fisheries: where there is an arrangement between the Commonwealth and the State, State laws may apply to fisheries in Australian waters beyond the coastal waters; that affects commercial and recreational fishers and any bodies that hold fisheries rights or licences in such areas, but only to the extent an arrangement is in place.

Entities holding rights under the Petroleum (Submerged Lands) Act framework. The definition of adjacent area in s 3(1) refers to Schedule 2 of the Petroleum (Submerged Lands) Act 1967 as in force immediately before commencement. Parties with interests, licences, permits or activities mapped to that adjacent area will be within the geographic ambit the Schedule uses and therefore potentially subject to State law under s 5 for the specified subjects.

Interplay with Commonwealth international obligations. Section 6 preserves Commonwealth responsibility for international law; therefore shipowners and international carriers may still rely on Commonwealth action to protect rights such as innocent passage and to implement international agreements. The schedule thus affects private actors whose activities are regulated by either State or Commonwealth law in marine areas, by shifting questions of primary legislative competence and creating routes by which State law can reach into coastal and adjacent waters.

Who does not gain new rights. Section 7(a) is explicit that nothing in the Act extends the limits of any State. So private parties do not obtain broader territorial rights in the legal sense of a State boundary extension; the Act is about legislative competence, not boundaries. Section 7(c) means that to the extent a State law is inconsistent with Commonwealth law or the Constitution, that State law will not have force; private actors must therefore continue to account for Commonwealth law where it applies.

In sum, the Act affects Commonwealth and State Parliaments and administrations, and private actors participating in seabed/subsoil operations, ports and shipping infrastructure, subterranean mining from land, and fisheries , subject to the geographic definitions and the existence of arrangements with the Commonwealth specified in the Schedule.

The Act and its Schedule do not create criminal offences or administrative licences by themselves. Instead, they allocate and preserve legislative authority and lay down interpretative and savings rules that define both rights to legislate and the limits on those rights. The principal duties and rights are institutional and legal rather than regulatory duties on individual persons.

Right of States to legislate in specified marine areas and subject matters. Under Schedule s 5(a), each State’s constitutional legislative powers extend to making laws as if the coastal waters of the State were within the State limits, including laws applying to the sea-bed, the subsoil beneath it, and the airspace above those coastal waters. That is a legal right of the States to exercise legislative competence in those areas and strata. The right is expressed as an extension of the legislative powers exercisable under each State constitution.

Right to extend State law beyond coastal waters for specified matters. Schedule s 5(b) grants a State power to make laws that have effect in waters within the State’s adjacent area but beyond the outer limits of its coastal waters for two categories of subject matter: (i) subterranean mining from land within State limits; and (ii) ports, harbours and other shipping facilities, installations, dredging and other coastal works. That is a targeted right to legislate to regulate particular activities that occur seaward of the coastal waters but within the adjacent area.

Conditional right in relation to fisheries. Schedule s 5(c) permits State laws with respect to fisheries in Australian waters beyond the coastal waters to apply, but only to the extent those fisheries are, under an arrangement to which the Commonwealth and the State are parties, to be managed under the State’s laws. This is a conditional right: it depends on the existence and terms of an intergovernmental arrangement with the Commonwealth.

Duty to respect international law and Commonwealth responsibilities. Schedule s 6 imposes no new private duty but declares that nothing in the Act affects the territorial sea’s status under international law or the Commonwealth’s rights and duties to ensure observance of international law, pointing in particular to the Convention on the Territorial Sea and the Contiguous Zone and the right of innocent passage. Practically, s 6 limits State law-making so that it must respect existing international law obligations in matters such as navigation and passage; it also identifies the Commonwealth as the institution with primary responsibility for ensuring observance of those obligations.

Savings on State actions. Schedule s 7 places three key limits: (a) the Act does not extend State boundaries, (b) it does not derogate from any other extraterritorial legislative power a State may already have, and (c) it does not validate any provision of a State law to the extent it is inconsistent with Commonwealth law or the Constitution. Subsection 7(c) is a declarative statement of the constitutional hierarchy; State laws inconsistent with Commonwealth law retain no force to the extent of the inconsistency.

Interpretive rule application. Schedule s 3(2) applies the Acts Interpretation Act 1901 as it stood immediately before the Royal Assent day to the interpretation of the Schedule. That imposes a duty on interpreters (courts, administrators) to read the Schedule using that frozen form of the Acts Interpretation Act.

Procedural duties arising elsewhere. The Victorian Act (s 1(2)) declares the Act’s commencement date as the day of Royal Assent for the Victorian instrument; the Schedule as a model Commonwealth Act provides for commencement by proclamation (Schedule s 2), which imposes a procedural duty on the Commonwealth to specify a proclamation date for the Commonwealth Act if it were enacted.

What the Act does not do. The Schedule does not itself impose enforcement mechanisms, create specific licensing schemes, or set penalties; nor does it alter State boundaries (s 7(a)). It leaves the details of law, enforcement, penalties and administrative schemes to be developed under State legislation enacted pursuant to the extended powers and subject to Commonwealth law and the Constitution.

The text supplied contains no express penalties, fines, or specific enforcement mechanisms. The Schedule is a power-conferring and definitional statute model rather than a regulatory code that establishes offences. Consequently, the Act leaves the creation of offences, penalties, permit schemes and enforcement arrangements to separate State laws enacted under the authority the Schedule describes and to Commonwealth laws where applicable.

Where enforcement will be exercised. Because Schedule s 5 extends the legislative powers of the States to the coastal waters and certain adjacent waters for specified subject matters, enforcement of substantive regulatory requirements in those domains would be exercised under the State laws that a State Parliament enacts pursuant to s 5. In other words, the Act confers competence; it does not itself prescribe enforcement arrangements. For example, if a State enacted a law regulating dredging in an adjacent area pursuant to s 5(b)(ii), that State’s statute would need to specify the offences, penalties, inspection powers and administrative enforcement procedures. The Schedule does not stipulate those details.

Limitations on enforcement where Commonwealth law applies. Schedule s 7(c) declares that nothing in the Act gives any force to a State law to the extent of any inconsistency with a law of the Commonwealth or the Commonwealth Constitution. The constitutional implication is that, even where a State purports to create an offence or regulatory regime under its extended powers, the enforceability of that regime may be negated to the extent it conflicts with Commonwealth legislation. Enforcement agencies and defendants must therefore account for possible Commonwealth pre-emption or constitutional invalidity in enforcement actions.

International law constraints on enforcement. Schedule s 6 preserves the Commonwealth’s rights and duties in relation to international law, including the right of innocent passage. State enforcement activities that would conflict with or impede internationally protected rights of passage would thereby be constrained; the Schedule identifies the Commonwealth as the actor responsible for ensuring observance of those international obligations. The Schedule itself does not set out how the Commonwealth enforces international-law-derived rights, but it reserves those responsibilities.

Potential for civil remedies before courts. Although the Act itself does not create private civil remedies, the conferral of State legislative power in respect of the sea-bed, subsoil and airspace (s 5(a)), ports and harbour works (s 5(b)), and fisheries subject to arrangements (s 5(c)) can give rise to State statutes that create civil regulatory regimes, licensing schemes and statutory causes of action. Whether a particular enforcement measure is available against a person will therefore depend on the text of State laws adopted under the Schedule’s authority and subject to the checks in s 7(c).

Administrative practicalities. The Schedule ties the territorial sea limits to determinations under the Seas and Submerged Lands Act 1973 and to agreements with other countries (s 4(1)). Enforcement agencies , whether State or Commonwealth , will need to operate with reference to those determinations and instruments to locate the legal boundaries where State law purports to apply. Where a determination increases the breadth of the territorial sea beyond three nautical miles, s 4(2) may exclude parts from the definition of coastal waters for the Act’s purposes; that will affect whether a State’s enforcement power applies in a given location. The model Act, however, leaves to later State statutes the task of specifying enforcement tools and penalties.

In short, this Schedule creates legislative competence but delegates the specification of penalties and enforcement mechanisms to the legislative instruments the States may subsequently enact, subject to Commonwealth law and international-law constraints preserved in the Schedule.

This Schedule explicitly cross-links to several Commonwealth statutes and constitutional provisions and sets out a non-derogation principle. Its interaction with other laws is therefore both direct and conditional.

Cross-reference to the Petroleum (Submerged Lands) Act 1967. The Schedule defines “adjacent area” by reference to the boundary described under the heading referring to each State in Schedule 2 to the Petroleum (Submerged Lands) Act 1967 “as in force immediately before the commencement of this Act” (s 3(1)). That means the geographic scope of the adjacent area is not self-contained but is anchored to an earlier Commonwealth statutory mapping. Any legal effect of a State law enacted under the Schedule that depends on the adjacent area will necessarily interact with rights, licences, and obligations deriving from the Petroleum (Submerged Lands) Act 1967 and its instruments as they were immediately before commencement. Administrators and courts must therefore interpret State measures with reference to that Commonwealth statutory mapping.

Dependence on Seas and Submerged Lands Act 1973 determinations. Section 4(1) establishes that the limits of the territorial sea of Australia for the purposes of the Schedule are those ascertained from time to time consistent with the Seas and Submerged Lands Act 1973 and instruments under it, and with any intergovernmental agreements about outer limits. Hence, the Schedule’s substantive geographic scope is tethered to determinations under the Seas and Submerged Lands Act 1973. Any Commonwealth instrument under that Act that defines outer limits will shift the geographic area that State law could, in principle, reach under Schedule s 5. The Schedule also expressly contemplates agreements with other countries affecting the outer limit.

Interaction with the Acts Interpretation Act 1901. The Schedule applies the Acts Interpretation Act 1901 in the form in which it was in force, as amended, immediately before the day the Schedule received Royal Assent (s 3(2)). That freezes interpretative rules to that historical form and means later amendments to the Acts Interpretation Act will not alter how the Schedule is to be read. That interacts with other Commonwealth and State instruments because it prescribes how the Schedule is to be construed relative to other statutory provisions and legislative instruments, including whether retrospective or prospective constructions are adopted.

Commonwealth constitutional supremacy and inconsistency. Schedule s 7(c) is an express non-validation clause: nothing in the Schedule gives force to a provision of a State law to the extent of any inconsistency with a Commonwealth law or with the Commonwealth Constitution. That places a clear constitutional interaction rule: State measures enacted under the Schedule are subject to the supremacy of Commonwealth law and the Constitution, and inconsistency will mean a lack of force. Consequently, where a State law enacted under the Schedule addresses a subject already governed by Commonwealth law, courts and administrators will need to apply the legal tests for inconsistency and supremacy to determine the operative regime.

International law obligations. Schedule s 6 declares that nothing in the Schedule alters the territorial sea’s status under international law or the Commonwealth’s rights and duties in relation to ensuring observance of international law, identifying the Convention on the Territorial Sea and the Contiguous Zone (and its right of innocent passage) in particular. This provision interacts with State laws by circumscribing State regulatory reach where international law imposes rules or protects certain uses (for example, navigation) that the Commonwealth is charged with overseeing. State laws must therefore be read and applied in a way that does not frustrate duly binding international obligations of the Commonwealth.

State extraterritorial powers and savings. Schedule s 7(b) preserves any extraterritorial legislative power a State might have apart from the Schedule. That creates an interaction whereby the Schedule adds to, but does not displace, existing extraterritorial principles a State may be able to rely on. Section 7(a) also clarifies that the Schedule does not extend State limits , it thus interacts with boundary and jurisdictional rules by leaving territorial lines legally unchanged even as it expands legislative competence to certain marine areas.

Potential overlapping jurisdictions. The Schedule’s extension of State legislative power over coastal waters and certain adjacent areas (s 5) sits alongside Commonwealth heads of power and duties. While the Schedule asks the Commonwealth to confer these State rights, the Schedule itself and the Victorian Act do not extinguish concurrent Commonwealth competence. The Schedule therefore contemplates a legal landscape in which State statutes made under s 5 will interact with Commonwealth statutes and international-law obligations, producing potential overlap and the need to resolve operational conflicts via the inconsistency principle in s 7(c).

In sum, the Schedule is designed to be read in a web of interrelated Commonwealth statutes and constitutional rules. It imports definitions and limits from the Petroleum (Submerged Lands) Act and the Seas and Submerged Lands Act, freezes interpretative rules to a particular historical version of the Acts Interpretation Act, preserves international-law obligations and Commonwealth responsibilities, and subjects State measures enacted under it to the supremacy of Commonwealth law and the Constitution.

The source contains explicit endnotes on amendment history. The endnotes state that there are no amendments made to the Constitutional Powers (Coastal Waters) Act 1980 by Acts and subordinate instruments (Endnotes: Table of Amendments). The instrument as presented carries a Version number (Version No. 003) and a version date “Version as at 23 August 2012,” but the accompanying endnote record indicates no statutory amendments had been made up to that publication point. The Victorian Act received Royal Assent on 18 March 1980 and came into operation on that date, per s 1(2) and the endnote summary.

The Schedule as model Commonwealth legislation is captioned Coastal Waters (State Powers) Act 1979. The Schedule contains a commencement clause (Schedule s 2) providing that the Commonwealth Act “shall come into operation on a date to be fixed by Proclamation.” That means any Commonwealth enactment adopting the Schedule would in its text leave commencement timing to proclamation, rather than automatic operation on assent.

Interpretive and definitional freeze dates. Schedule s 3(2) applies the Acts Interpretation Act 1901 “in the form in which it was in force, as amended, immediately before the day on which this Act received the Royal Assent,” to the interpretation of the Schedule. Similarly, Schedule s 3(1) defines “adjacent area” by reference to the Petroleum (Submerged Lands) Act 1967 “as in force immediately before the commencement of this Act.” Both clauses demonstrate that the drafters built temporal anchors into the Schedule so that certain external references are fixed at historic moments rather than floating to future amendments. Those anchors are relevant for any future amendment exercises because they may limit the effect of later amendments to the external instruments on the Schedule’s meaning unless the Schedule itself is amended.

No recorded subordinate instruments. The endnotes indicate no subordinate instruments have amended the Act. The Schedule’s provisions that tie the territorial sea limits to instruments under the Seas and Submerged Lands Act 1973 (s 4(1)) leave room for future intergovernmental or executive action to change the geographic facts the Schedule uses, but any subsequent amendments to the Schedule text itself are not recorded in the supplied endnotes.

Practical implication of the amendment record. The legislative record available in the source shows a model act proposed and a State request for Commonwealth enactment, with no subsequent recorded amendments to the State instrument in the source. The model Act’s commencement-by-proclamation clause and its cross-references to Commonwealth instruments as in force at particular historical moments point to a statutory architecture designed for relative stability of interpretive anchors and for the Commonwealth to set operational timing. Any future amendment history would be recorded in official legislative amendment tables if changes were made; none appear in the provided endnotes.

The material supplied contains no reported cases, litigation notes or judicial citations. The Endnotes include a section called “Explanatory Details” with the note “No entries at date of publication” and the Table of Amendments shows no amendments were made; there is no litigation history recorded in the text provided. Consequently, the Schedule does not, within this source, present a body of judicial interpretation or precedent to explain its operation. The absence of recorded litigation in the provided source does not mean litigation has never occurred in general, but it does mean that the Act’s text as provided contains no internal references to judgments or cases.

Potential sources of litigation suggested by the text. Although the Schedule itself does not report litigation, its provisions contain several features that could generate legal disputes if contested in practice:

• Geographic limits and determinations. Section 4(1) anchors the territorial sea limits to determinations under the Seas and Submerged Lands Act 1973 and to intergovernmental agreements with other countries. Disputes about the correct outer limit of the territorial sea ascertained under those instruments could give rise to litigation over whether a particular location falls within the coastal waters of a State for the purposes of State legislation enabled by the Schedule.

• Application of s 4(2) when breadth exceeds three nautical miles. Section 4(2) provides that if the territorial sea breadth is determined to be greater than three nautical miles, references to coastal waters do not include parts that would not have been within a three-nautical-mile limit. That provision could raise litigation over whether a particular part of the territorial sea is excluded from the Schedule’s definition of coastal waters, and consequently whether a State law applies.

• Inconsistency questions under s 7(c). Section 7(c) provides that nothing in the Schedule gives force to State law to the extent of any inconsistency with Commonwealth law or the Constitution. Litigation could arise where a State enacts laws under the Schedule that a party alleges are inconsistent with Commonwealth law or the Constitution. Courts would then be required to determine the extent of inconsistency and the operative law.

• Scope of State powers under s 5. The breadth of State laws enacted under s 5 , particularly laws purporting to regulate seabed and subsoil activities, ports and harbours, dredging, or fisheries in adjacent areas , could generate disputes about whether such laws fall within the subject matter authorised by s 5, and whether they are valid when read against Commonwealth powers and international obligations preserved by s 6.

• Interaction with international law preserved by s 6. Litigation could turn on whether a State law improperly interferes with internationally protected rights (for example, innocent passage) whose observance is the Commonwealth’s duty to ensure under s 6. Parties affected by State measures that restrict or regulate passage or activities protected by international law might test those measures in court.

Absence of judicial gloss in the source. Because the provided instrument contains no judicial decisions, practitioners must rely on primary legislation and constitutional principles to forecast outcomes and should be prepared to litigate novel questions raised by the Schedule’s territorial and subject-matter provisions. The Schedule creates definitional and allocation rules that, if enacted by the Commonwealth and then operationalised by State legislation, would likely produce litigation on geographic boundaries, overlap with Commonwealth law, and the limits of State competence in areas touched by international law.

The Schedule contains several drafting features and cross-references that can produce unexpected consequences unless carefully understood. Below are concrete things that can catch users, administrators and counsel off guard, with references to the relevant provisions.

Cross-references fixed at historical moments. The definition of “adjacent area” is given by reference to Schedule 2 to the Petroleum (Submerged Lands) Act 1967 “as in force immediately before the commencement of this Act” (Schedule s 3(1)), and the Acts Interpretation Act is applied in the form “as amended, immediately before the day on which this Act received the Royal Assent” (Schedule s 3(2)). These phrases freeze certain external references to a historical version rather than allowing them to float with later amendments. A practitioner who assumes the adjacent area definition will track later amendments to the Petroleum Act or who assumes current interpretative rules apply may be surprised. The “immediately before” temporal anchors mean that later changes to those external Acts will not alter what the Schedule imported at commencement unless the Schedule itself is amended.

Territorial sea breadth qualification. Section 4(2) limits the references to coastal waters in the Schedule if the breadth of the territorial sea is determined to be greater than three nautical miles. The effect is that some parts of the territorial sea could be excluded from the Schedule’s definition of coastal waters if they would not have been within the limits had the breadth remained three nautical miles. This is a non-intuitive carve-out: a later declaration expanding the territorial sea could produce a counter-intuitive reduction in the parts of the territorial sea treated as “coastal waters” for the purposes of State law under this Schedule. Practitioners should not assume that an expanded territorial sea automatically increases State legislative reach under the Schedule.

Dependence on Commonwealth instruments for geographic reach. Section 4(1) ties the limits of the territorial sea to determinations under the Seas and Submerged Lands Act 1973 and any agreements with other countries. That means the spatial reach of State law under the Schedule is partly contingent on Commonwealth determinations and international agreements. Private parties and State regulators cannot unilaterally fix the geographic boundaries for the Schedule’s application; they must look to Commonwealth instruments and agreements, which may be technical, complex or subject to diplomatic negotiation.

No direct enforcement or penalties in the Schedule. The Schedule grants competence but contains no enforcement provisions, penalties or administrative regimes. That is a practical gotcha: stakeholders cannot rely on the Schedule for enforcement mechanisms but must instead look to the State statutes that will be enacted under the Schedule to see what enforcement tools, offences and penalties exist. Absent such statutes, the Schedule grants only the capacity to legislate.

Subject-matter limitations in the adjacent area. Section 5(b) permits State laws in the adjacent area beyond the coastal waters only in relation to, inter alia, subterranean mining from land within State limits and ports, harbours and other shipping facilities and coastal works. The scope is narrower than the broad grant in s 5(a) for coastal waters. Expect disputes and potential regulatory gaps where State authorities attempt to regulate other activities in adjacent areas without a clear textual basis in s 5(b) or an arrangement under s 5(c) for fisheries.

Fisheries constraint requires an arrangement. Section 5(c) allows State fisheries laws to apply beyond coastal waters only “to the extent to which those fisheries are, under an arrangement to which the Commonwealth and the State are parties, to be managed in accordance with the laws of the State.” That means unilateral State assertion over fisheries outside coastal waters is not authorised by the Schedule; there must be an arrangement. Parties assuming State control over fisheries beyond coastal waters without an arrangement risk having the law held ineffective in that domain.

Inconsistency risk. Schedule s 7(c) explicitly prevents the Schedule from giving force to an inconsistent State law. That is not merely theoretical: any State law enacted under the Schedule that conflicts with Commonwealth law (or the Constitution) will lack force to the extent of inconsistency. Actors relying on State-level regulatory instruments for legal certainty must therefore check for Commonwealth legislation that may pre-empt or displace State measures.

International law and innocent passage. Section 6 preserves the Commonwealth’s duty to ensure international law observance, including the Convention on the Territorial Sea and the Contiguous Zone’s right of innocent passage. A State regulatory measure that impedes innocent passage or otherwise conflicts with these international obligations risks being constrained by Commonwealth action or judicial review. Entities engaged in navigation or shipping should be alert to Commonwealth-level protections that might limit the effect of State regulatory measures.

Proclamation commencement for Commonwealth adoption. The Schedule assumes commencement by proclamation (Schedule s 2). If the Commonwealth enacts the Schedule, the timing of commencement may be subject to proclamation and may therefore be delayed or staged by executive decision. Stakeholders and counsel should not assume immediate effect upon enactment and must track proclamation timing.

Taken together, these drafting features , fixed cross-references, territorial sea carve-outs, subject-matter limits, the need for arrangements for fisheries, and the supremacy/inconsistency savings , create several concrete legal and operational pitfalls that need active management by States, regulated entities and advisers.

Because the Schedule is a competence-granting instrument rather than an operational regulatory code, compliance is a two-step exercise: (1) determine whether a particular location, activity or entity falls within the Schedule’s geographic and subject-matter scope; and (2) comply with the State law enacted under the Schedule for the relevant domain, while ensuring consistency with Commonwealth law and international obligations preserved in the Schedule.

Step 1 , Determine geographic and subject-matter applicability:

• Map the location. Use the territorial sea limits ascertained under the Seas and Submerged Lands Act 1973 and instruments under that Act and any relevant bilateral agreements, because Schedule s 4(1) ties the coastal waters limits to those determinations. Practitioners must obtain the relevant instruments and maps to identify whether a site is within coastal waters as defined in the Schedule.

• Check the adjacent area. The Schedule defines adjacent area by reference to Schedule 2 to the Petroleum (Submerged Lands) Act 1967 as in force immediately before commencement (s 3(1)). Obtain that historical Schedule 2 text as it stood immediately before commencement to determine whether the activity falls within the adjacent area. Do not assume later amendments to the Petroleum Act change this reference.

• Apply the 3-nautical-mile qualification. If the territorial sea breadth has at any time been declared greater than three nautical miles, apply s 4(2): references to coastal waters in the Schedule exclude parts that would not have been within limits had the breadth remained three nautical miles. Practically, this means calculating whether the relevant part would have fallen within a 3 nm limit.

• Classify the activity. Identify whether the activity is: (a) one for which s 5(a) authorises State law because it occurs in coastal waters (for example seabed, subsoil or airspace-related matters); (b) one of the s 5(b) categories in the adjacent area beyond coastal waters (subterranean mining from land within State limits, ports/harbours/ installations, dredging/coastal works); or (c) fisheries beyond coastal waters, which require an arrangement between the Commonwealth and the State under s 5(c) for State law to apply.

Step 2 , Determine applicable legal instruments and compliance obligations:

• Identify State statute. Where the State has enacted legislation under the Schedule’s authority, obtain and read the State statute carefully for licensing requirements, operational standards, reporting duties, inspection powers, offences, penalties and appeal or review paths. The Schedule does not prescribe these details.

• Check for Commonwealth law or Constitution conflicts. Before relying on a State regulatory rule, check whether there is any Commonwealth law that relates to the same subject-matter and whether the State provision would be inconsistent; s 7(c) makes clear that inconsistent State law has no force to the extent of the inconsistency. If there is a potential overlap, seek legal advice on inconsistency risk and consider regulatory dual-tracking or seeking Commonwealth approvals.

• Check international-law constraints and Commonwealth duties. Activities such as navigation and passage may be protected by international law obligations the Commonwealth must ensure (s 6). Ensure State compliance measures do not inadvertently impede internationally protected activities; where in doubt, coordinate with Commonwealth authorities.

• For fisheries, confirm the existence of an intergovernmental arrangement. State fisheries law will apply beyond coastal waters only where an arrangement between the Commonwealth and the State exists and specifies management under State laws (s 5(c)). Before assuming State regulatory control, obtain and review any such arrangement.

Practical compliance steps for regulated entities:

• Obtain authoritative maps and instrument texts. Secure the Seas and Submerged Lands Act instruments, the historical Schedule 2 to the Petroleum (Submerged Lands) Act 1967 as it stood immediately before commencement, and any relevant State statutes enacted under the Schedule. Do not rely on informal or secondary sources for boundary determinations.

• Regulatory impact mapping. For a proposed activity (e.g., a dredging project, a seabed installation, or a land-based subterranean mining operation extending into the adjacent area), prepare a regulatory map identifying which State laws, Commonwealth laws and international-law rules may apply, and where overlap or inconsistency risks arise.

• Licensing and permits. Identify what State licences or approvals will be required under the State law enacted pursuant to s 5. Build timelines for State licensing processes and coordinate with Commonwealth approvals where relevant.

• Contract drafting. For commercial contracts (e.g., port works, dredging, resource development), include clauses that allocate risk for legal uncertainty over jurisdictional boundaries, delay risks while maps and instruments are confirmed, and the risk of Commonwealth pre-emption under s 7(c). Preserve rights to seek clarifying relief if boundaries or legal competence are contested.

• Engage early with regulators. Where activities are likely to fall into the adjacent area categories, engage early with State regulators to determine their regulatory expectations and with Commonwealth agencies to ensure coordination where international obligations or Commonwealth interests are engaged.

• Monitor proclamations and instruments. If and when the Commonwealth enacts the Schedule or an equivalent, monitor for the proclamation date (Schedule s 2 for commencement) and for any instruments under the Seas and Submerged Lands Act 1973 that define limits. The Schedule’s practical effect depends on these dates and instruments.

• Legal audit for inconsistency risk. Conduct a legal audit for potential conflicts with Commonwealth law and constitutional limits, particularly in areas such as navigation, fisheries management and resource development, and seek advice on mitigation measures.

In short, compliance requires a fact-sensitive mapping exercise anchored to the external instruments the Schedule imports, an audit of applicable State statutes enacted under the Schedule, vigilance about Commonwealth pre-emption, and operational coordination with both State and Commonwealth authorities where activities touch international-law-protected uses or cross jurisdictional lines.
