Petroleum Revenue Act 1985

The Act is built around a small set of statutory concepts that determine eligibility for the excise exemption and the administrative steps required to bring it into effect. These concepts are defined in s 3 and used throughout ss 4-8.

• Petroleum, market petroleum and prescribed petroleum. Section 3 defines “petroleum” expansively to cover any naturally occurring hydrocarbon in gaseous, liquid or solid state, any naturally occurring mixture of hydrocarbons, and naturally occurring mixtures of hydrocarbons with certain non‑hydrocarbon constituents (hydrogen sulphide, nitrogen, helium, carbon dioxide). The Act includes reservoirs where petroleum has been returned. “Market petroleum” is petroleum in a form commonly sold or a product derived from petroleum commonly sold, but excludes a petroleum or product that is derived from petroleum to which paragraph (a) applies, or from a product to which paragraph (b) applies. “Prescribed petroleum” is a narrower subset: stabilised crude oil; liquid petroleum obtained from naturally occurring petroleum gas; and liquefied petroleum gas obtained from unstabilised crude oil or naturally occurring petroleum gas (s 3).

• Production source and production unit. “Production source” is defined as a source of petroleum in a State, which may include a production area within the meaning of s 5B of the Excise Tariff Act 1921, or two or more such sources that constitute or form part of a project for production (s 3). A “production unit” pairs a production source with the plant and facilities used in, or in relation to, the production of market petroleum from that source, excluding plant and facilities used for refining or transport of market petroleum (s 3). The distinction focuses the exemption on upstream production and associated plant rather than midstream or downstream refining and transport.

• Relevant resource rent royalty agreement and relevant revenue‑sharing agreement. These are agreements described in Schedule 1 and Schedule 2 respectively and are the trigger instruments for the Commonwealth’s involvement (s 3). The Act does not itself reproduce those Schedules in the text provided; therefore the detailed content and thresholds that make an agreement “relevant” are located in the Schedules.

• Temporal trigger. The royalty must be “in respect of market petroleum produced from that unit on or after 1 July in a year after 1984 specified in the agreement” (s 5(a), s 6(1)(a)). That places the Act’s operation on production from a specified 1 July date in the relevant agreement.

• Administrative certification and Gazette declaration. The Minister must provide a certificate to the Excise Minister once the bilateral agreement conditions are satisfied (s 6(1)). The Excise Minister then publishes in the Gazette a declaration that the prescribed petroleum from the specified source is exempt, subject to exclusions for production before the specified 1 July and production after revocation (s 6(2)). Revocation follows by similar certificate and Gazette notice when the underlying agreements cease to be in force (s 6(3)-(4)).

• Interaction with excise law. For the purposes of the Excise Act 1901, prescribed petroleum exempted under s 6 is not to be taken to be excisable goods and any entry purporting to have been made under s 58 of the Excise Act shall be taken not to have been made (s 7(1)). Subsection 7(2) preserves existing Departmental By‑laws and permits the making of particular by‑laws for definitions of production areas in the Excise Tariff Act 1921.

• Non‑discrimination constraint. Section 4 requires the Commonwealth or the Minister not to exercise powers under this Act or a relevant revenue‑sharing agreement in a manner that would discriminate among States within the meaning of paragraph 51(ii) of the Constitution or give preference to one State over another within the meaning of s 99 of the Constitution (s 4). This is a procedural and constitutional compliance constraint on Commonwealth decision‑making under the Act.

• Repayment interest rule. Where amounts paid by way of duties of Excise are repayable because of this Act, no interest on those amounts is payable (s 8(1)-(2)). The subsection clarifies that it does not imply that interest would otherwise have been payable or that interest is payable on other excise repayments (s 8(2)).

These concepts determine who can obtain the excise exemption (producers of prescribed petroleum from a production source covered by the agreements), what product is covered (the statutory categories of prescribed petroleum), what procedural steps are required (State request, Commonwealth revenue‑sharing agreement, Minister’s certificate, Excise Minister Gazette declaration), and what statutory limits apply (exclusions for earlier or later production, constitutional nondiscrimination constraints, and no interest on repayments).

The Act allocates rights, duties and administrative roles across three distinct categories of actors: States, producers (persons who produce market petroleum), and Commonwealth officials (the Minister and the Minister administering the Excise Tariff Act 1921, here called the Excise Minister). It also engages those who administer excise law and anyone who pays or receives excise duties.

• States. The Act contemplates State initiation and consent: a State must have entered into a relevant resource rent royalty agreement with producer(s) (s 5(a)) and must request the Commonwealth to enter into a relevant revenue‑sharing agreement (s 5(b)). The State is therefore a necessary cooperative actor. The State’s agreements are also the trigger for the Commonwealth’s further action and for the excise exemption certificate (s 6(1)).

• Producers or persons who produce market petroleum. The Act expressly targets “the person or persons who produce market petroleum from a production unit” (s 5(a)). These producers must be parties to a relevant resource rent royalty agreement with a State that contemplates production on or after the specified 1 July. The production unit definition (plant and facilities used in, or in relation to, production, excluding refining or transport plant) specifies the asset base and activities bound up in the agreements and the exemption (s 3).

• Commonwealth Ministers and administrative officials. The Minister has two roles: the discretionary power to arrange for the Commonwealth to enter into a relevant revenue‑sharing agreement (s 5), and the mandatory duty to give the Excise Minister a certificate when the specified conditions exist (s 6(1)). The Excise Minister must publish a Gazette notice declaring the excise exemption once the Minister’s certificate is given (s 6(2)) and must revoke that declaration on the Minister’s certificate that the declaration should be revoked (s 6(4)). The Act therefore creates a sequence of ministerial obligations and duties.

• Revenue authorities and those operating under the Excise Act. For the purposes of excise administration, prescribed petroleum covered by a s 6 declaration is not to be taken as excisable goods under the Excise Act 1901 (s 7(1)). This affects customs/excise accounting, record‑keeping and refund processes, given that any purported entry under s 58 of the Excise Act shall be taken not to have been made (s 7(1)). Departments responsible for by‑laws under the Excise Act retain continuing functions per s 7(2).

• Payors and recipients of excise duties. The Act contemplates situations where excise duties paid may be repayable because of the exemption. Section 8 addresses the financial consequence: no interest is payable on such repayments (s 8(1)). That affects cashflow outcomes for taxpayers and for government payments.

• Legal and regulatory advisers to these actors. Companies producing petroleum, accounting and compliance teams, and State and Commonwealth legal teams will be engaged to negotiate the resource rent royalty and revenue‑sharing agreements, to prepare and process the Minister’s certificate, and to ensure compliance with production date requirements and the classification of “prescribed petroleum” (s 3, s 5-6).

The Act also implicitly affects third parties dealing with products derived from market petroleum. The definitions of “market petroleum” and “prescribed petroleum” in s 3 create lines between products that are covered and products that are excluded. The Act excludes plant and facilities used in refining or transport from the definition of production unit (s 3), which means downstream operators engaged in refining or transport are not directly covered by the exemption even if they handle the exempted product after it leaves the production unit.

Finally, the constitutional limits in s 4 make the Act relevant to any constitutional challenges or considerations about discriminatory treatment between States. The Act’s design therefore places States and producers at the centre of initiating contractual arrangements, with Commonwealth ministers responsible for translating those arrangements into excise law outcomes for specified categories of petroleum (s 4-6).

The Act creates specific, one‑way administrative duties on Commonwealth ministers and related rights for States and producers. The following paragraphs map the statutory commands and the legal entitlements that flow from them, with section references.

Duties and obligatory acts

• Minister’s arranging power. Where a State requests it, the Minister may arrange for the Commonwealth to enter into a relevant revenue‑sharing agreement with the State, provided the State and producers have already entered into a relevant resource rent royalty agreement (s 5). The verb “may” indicates an administrative discretion to effect the Commonwealth’s entry into the revenue‑sharing agreement; the Act does not mandate the Minister to arrange entry in every instance of a State request.

• Minister’s certificate duty. Once the two preconditions in s 6(1) are met , that is, the State and producers have a relevant resource rent royalty agreement providing for a royalty in respect of market petroleum produced on or after the specified 1 July, and the Commonwealth and State have entered into the relevant revenue‑sharing agreement , the Minister shall give the Excise Minister a certificate in writing stating that it is appropriate that prescribed petroleum produced from that source on or after that 1 July should be exempt from duties of Excise (s 6(1)). The word “shall” imposes a mandatory duty on the Minister to issue the certificate once the conditions are present.

• Excise Minister’s declaration and revocation duties. Upon receipt of the Minister’s certificate, the Excise Minister shall, by notice in the Gazette, declare that the prescribed petroleum from the source (other than petroleum produced before the specified 1 July or after revocation) is exempt from duties of Excise (s 6(2)). If subsequently either the resource rent royalty agreement or the revenue‑sharing agreement ceases to be in force, the Minister shall give the Excise Minister a certificate that the declaration should be revoked (s 6(3)), and the Excise Minister shall, by Gazette notice, revoke the declaration (s 6(4)). These duties create a clearly sequential administrative process for giving and withdrawing the excise exemption.

Rights and entitlements

• Right to an excise exemption where conditions are met. Producers of prescribed petroleum from a production source covered by the agreements obtain an entitlement to have that petroleum exempted from excise duties for production on or after the 1 July specified in the agreement and before any revocation (s 6(1)-(2)).

• Non‑treatment as excisable goods for excise purposes. For the purposes of the Excise Act 1901, prescribed petroleum that is exempt under s 6 is not to be taken to be excisable goods and any entry purporting to have been made under s 58 of that Act shall be taken not to have been made (s 7(1)). This is a substantive reclassification for excise law purposes.

Constraints and limits on duties and rights

• Temporal limitation. The exemption is limited to production on or after the specified 1 July cited in the relevant resource rent royalty agreement and excludes production before that date and production after revocation (s 6(1)-(2)).

• Product limitation. The exemption applies only to “prescribed petroleum” as defined in s 3. Other petroleum or derivative products fall outside the statutory exemption unless they meet the prescribed petroleum definition.

• Constitutional constraint. Section 4 restricts the manner in which the Commonwealth or the Minister may exercise powers under this Act or under a relevant revenue‑sharing agreement. The Commonwealth or Minister must not exercise powers in a way that would amount to discrimination between States within the meaning of paragraph 51(ii) of the Constitution, or give preference to one State over another within the meaning of s 99 of the Constitution (s 4). This operates as a legal constraint on how the powers conferred by this Act and the associated agreements can be exercised.

• Treatment of departmental by‑laws. Section 7(2) preserves Departmental By‑laws under the Excise Act 1901 that were in force immediately before commencement and allows for making new by‑laws in respect of certain definitions in the Excise Tariff Act 1921. This means excise administrators retain regulatory tools that interact with the exemption.

Financial consequence duties

• No interest on repayments. Where excise amounts are repaid because of the operation of this Act, subsection 8(1) says interest on those amounts is not payable to the recipient. Subsection 8(2) clarifies that this does not imply interest would otherwise have been payable or that interest is payable on other excise repayments (s 8).

Operational duties for producers and States

• Agreement formation and requests. The practical duties for States and producers are to negotiate, enter into and maintain the relevant resource rent royalty agreements and revenue‑sharing agreements in ways that keep them within the “relevant” definitions in the Schedules (s 3, s 5). If an agreement is varied so that it ceases to be a relevant agreement, s 3(3) provides that the agreement ceases to be in force for the purposes of this Act.

Record‑keeping and administrative obligations follow from these duties: producers and States must be able to demonstrate to the Minister and the Excise Minister that the statutory preconditions exist and that production dates and product classifications meet the Act’s definitions.

In short, the Act creates mandatory procedural duties for the Minister and the Excise Minister tied to contractual prerequisites at the State-producer level, clarifies the excise classification consequences once a declaration is published, and limits financial consequences through the no‑interest rule for repayments (s 5-8). The non‑discrimination constraint in s 4 overlays these duties with a constitutional boundary.

The Act supplies no express criminal penalties, monetary fines, administrative sanctions or enforcement mechanisms within its own text. The enforcement architecture is procedural and administrative rather than punitive, with the principal statutory enforcement features being the certification, Gazette declaration and the statutory reclassification of prescribed petroleum for excise law purposes.

Administrative enforcement mechanisms

• Gazette declaration and revocation. The operational “enforcement” mechanism is the public Gazette declaration and revocation process administered by the Excise Minister on receipt of the Minister’s certificate (s 6(2), s 6(4)). The declaration determines legally whether petroleum from a specified production source is to be treated as exempt from excise duties. The revocation mechanism is symmetrical and mandatory once the Minister certifies revocation is appropriate (s 6(3)-(4)).

• Reclassification under the Excise Act. Section 7(1) has the effect of removing prescribed petroleum that is the subject of a s 6 declaration from the legal category “excisable goods” under the Excise Act 1901. Any purported entry under s 58 of the Excise Act is taken not to have been made (s 7(1)). Those statutory effects operate as operational enforcement levers for excise administration: the declaration determines the legal status of goods for excise accounting and reporting.

Absence of express penalties in this Act

• No offences or penalties. The Act does not create offences, fines, or criminal sanctions for non‑compliance with its procedural rules. It also does not specify civil remedies or administrative penalties that flow directly from contravening duties in this Act.

• Enforcement through other legislation and administrative processes. Enforcement and sanctions related to excise non‑compliance therefore remain in the machinery of the Excise Act 1901 and other relevant taxation or customs statutes. The Act’s reclassification of goods will change how those other provisions apply, but any punitive measures will be those located in the existing excise laws, not in this Act.

Financial consequences

• Repayments and interest. Where excise has been paid but is later repayable because of the operation of this Act, s 8 provides that no interest is payable on the repaid amounts (s 8(1)-(2)). This limits the financial exposure to interest payments when repayments are made and is therefore a financial control rather than a punitive measure.

Potential for dispute and administrative review

• Administrative certainties and disputes. The statutory deployment of the Minister’s certificate and Gazette declaration centralises decision‑making in ministers, which could produce administrative disputes over whether the preconditions in s 6(1) exist, whether the Minister should or may enter into a revenue‑sharing agreement under s 5, or whether an agreement has been varied so as to cease to be relevant under s 3(3). Any legal challenge would proceed via the usual channels for judicial review of administrative action or statutory construction disputes, but the Act itself sets no special tribunal or penalty regime.

• Constitutional constraints as a legal boundary. Section 4’s directional prohibition against discriminatory or preferential exercises of power under the Act (with explicit reference to constitutional provisions) imposes a legal limit whose breach could be the subject of constitutional litigation; the Act itself does not prescribe remedies but the usual constitutional enforcement mechanisms would be engaged.

In sum, enforcement under this Act operates through administrative classification and ministerial action (certificates and Gazette notices), and through the interaction of those actions with existing excise law machinery. The Act does not itself prescribe penalties or create new offences, and it limits financial exposure by withholding interest on repayments made because of its operation (s 6-8).

The Act is explicitly designed to operate in conjunction with State resource rent royalty agreements and Commonwealth excise legislation. The text references and modifies concepts in the Excise Act 1901 and the Excise Tariff Act 1921, and it situates Commonwealth action within constitutional constraints. The principal interactions are as follows, set out with section references.

Interaction with State agreements

• Triggering agreements. The statutory mechanism requires two layers of agreement: a State-producer “relevant resource rent royalty agreement” and a Commonwealth-State “relevant revenue‑sharing agreement” (s 5, s 6(1)). The Act does not prescribe the full content of those agreements in the operative sections; instead it references Schedule 1 and Schedule 2 for descriptions of the relevant agreements (s 3). The Commonwealth’s administrative duties under s 5 and s 6 flow from those agreements.

Interaction with the Excise Act 1901

• Reclassification of excisable goods. Section 7(1) provides that, for the purposes of the Excise Act 1901, prescribed petroleum exempted under s 6 is not to be taken as excisable goods and any entry purporting to have been made under s 58 of the Excise Act is taken not to have been made. That is a direct statutory override of the Excise Act classification for the specified petroleum during the period the s 6 declaration is in effect (s 7(1)). It thereby affects accounting, returns, and administrative entries that would otherwise be required under s 58 of the Excise Act.

• Preservation and power to make Departmental By‑laws. Section 7(2) saves Departmental By‑laws under the Excise Act that were in force immediately before commencement, and does not prevent the making of new by‑laws prescribing petroleum production areas, new production areas, condensate production areas, and intermediate petroleum production areas as defined in provisions of the Excise Tariff Act 1921 (s 7(2)(a)-(c), (ba)). This preserves and permits excise administrators’ regulatory instruments that define and delimit production areas used in excise regulation.

Interaction with the Excise Tariff Act 1921

• Definitional references. Section 3 notes that “production source” may be a production area within the meaning of s 5B of the Excise Tariff Act 1921 (s 3). Section 7(2) also specifically references subsections of the Excise Tariff Act 1921 (ss 6B(1), 6C(1), 6CA(1), 6D(1)) when preserving or permitting Departmental By‑laws (s 7(2)). The Act therefore delegates some definitional work and regulatory reach to the Excise Tariff Act 1921 and its by‑laws.

Interaction with the Constitution

• Non‑discrimination requirement. Section 4 imposes a statutory prohibition on the Commonwealth or Minister exercising powers under the Act or a relevant revenue‑sharing agreement in a way that would discriminate between States within the meaning of paragraph 51(ii) of the Constitution or give preference to one State over another within the meaning of s 99 of the Constitution (s 4). This places the Act’s exercise within the constitutional framework governing discrimination and preference, and establishes a legal limit on how the Commonwealth may structure or administer revenue‑sharing arrangements.

Interaction with other administrative law regimes

• Ministerial certification and public notice. The Act places administrative duties on Ministers to issue certificates and for the Excise Minister to publish Gazette notices (s 6). These actions will be subject to standard administrative law principles and, where relevant, judicial review, though the Act itself does not set out special review procedures.

Financial and tax administration

• Repayment and interest treatment. Where excise payments become repayable because of the operation of the Act, s 8 removes entitlement to interest on the repaid amounts (s 8(1)-(2)). This interacts with general rules in taxation and excise law about refunds and interest on overpayments, by creating a specific carve‑out for repayments traceable to this Act.

Limits of the Act with respect to other laws

• Exclusion of refining and transport. The definition of production unit excludes plant and facilities used in, or in relation to, the refining or transport of market petroleum (s 3). This clarifies that downstream regulatory regimes for refining and transport remain governed by their applicable laws and by excise classification where the exemption does not apply.

• Schedules govern “relevant” agreements. The Act’s substantive triggers refer to Schedules 1 and 2 for the description of the “relevant” agreements (s 3). Absent those Schedules in the text supplied here, the reader must look to the Schedules for the detailed contractual or definitional elements that govern whether a resource‑rent royalty agreement or revenue‑sharing agreement is “relevant” for the purposes of triggering Commonwealth action.

In short, the Act operates as a bridge between State‑level royalty arrangements and Commonwealth excise law, modifying the operation of the Excise Act for specified petroleum produced from specified production sources where the contract and administrative steps have been completed. It preserves and works alongside the Excise Tariff Act 1921 mechanisms for defining production areas and delegates definitional content to those statutes and to Departmental By‑laws. The operation is constrained by constitutional limits on discrimination and preference set out in s 4.

The text supplied contains the Act as numbered ss 1-8 and footnotes attached to ss 1 and 2 stating “[see Note 1]”. The text supplied does not contain a Schedule 1 or Schedule 2, and it does not include any legislative amendment notes, repeals, or a chronology of legislative changes within the body of the material provided. Accordingly, the following is a description of the Act’s amendment record constrained to the supplied text:

• The Act as supplied is composed of eight sections with no express amending notes embedded in those sections. Sections 1 and 2 carry a parenthetical “[see Note 1]” which indicates that explanatory notes or legislative history may be recorded elsewhere in the original printed statute or an official reprint, but those notes are not included in the text provided here.

• No schedules are present in the supplied material. The Act’s operative provisions (for example the definitions of “relevant resource rent royalty agreement” and “relevant revenue‑sharing agreement”) refer to Schedules 1 and 2 for detailed descriptions (s 3). Because those Schedules are not present, any amendments that may have been made to the Act via later insertions, deletions or changes to the Schedules are not visible in the text provided.

• The Act’s cross‑references to other statutes (the Excise Act 1901 and the Excise Tariff Act 1921) and to constitutional provisions (paragraph 51(ii) and s 99) are intact in the supplied text, but the supplied text does not show any historical amendments to those cross‑references or to the sections themselves.

• The absence of included Schedules and the “[see Note 1]” markers mean that this presentation cannot be used to determine whether the Act has been subsequently amended, whether particular subsections have been added or repealed, or whether the Schedules were modified. Any authoritative amendment history, including dates of royal assent, commencement proclamations under s 2, or subsequent amending Acts, would need to be obtained from the consolidated statute or an official legislative database.

• The Act provides for commencement by proclamation (s 2). The supplied text gives the commencement provision but does not include a proclamation date. Consequently, the supplied text does not itself record the commencement date; that is recorded by Proclamation in the official instruments not reproduced here (s 2).

In short, the supplied Act text does not include a recorded amendment history, and it omits Schedules and any legislative notes that would otherwise indicate changes over time. The “[see Note 1]” markers at the head of ss 1 and 2 indicate that contextual notes exist in the formal printed statute or reprint but are not included here. To assemble a reliable amendment history, one must consult the official consolidated version or parliamentary records that list amendments, commencement proclamations and any Schedule changes.

The statute as supplied does not include any citations to case law, reported decisions, or specific judicial interpretations. There are no judicial decisions or litigation summaries embedded in the text. The Act itself does not name any legal proceedings, and there are no notes within the supplied material enumerating cases that have construed its provisions. Therefore the following observations are limited to what the Act expressly identifies as potentially litigable issues and to the statutory features that make litigation a foreseeable possibility.

Statutory features that bear on potential litigation

• Constitutional limitations. Section 4 expressly requires the Commonwealth or the Minister not to exercise powers under this Act or under a relevant revenue‑sharing agreement in a way that would discriminate between States within the meaning of paragraph 51(ii) of the Constitution or give preference to one State over another within the meaning of s 99 of the Constitution (s 4). Those constitutional constraints are recognised bases for litigation. The Act’s text itself points to constitutional law as a legal limit on Commonwealth action, which means disputes over whether a particular exercise of power contravenes the constitutional non‑discrimination or preference prohibitions would be resolved by the courts applying constitutional principles.

• Contractual scope and “relevant” agreements. The Act’s operation depends on whether agreements are “relevant” as described in Schedules 1 and 2 (s 3). Section 3(3) further provides that where an agreement that is a relevant resource rent royalty agreement is varied so that it ceases to be a relevant agreement, that agreement ceases to be in force for the purposes of the Act (s 3(3)(a)), and similarly for a revenue‑sharing agreement (s 3(3)(b)). Disputes over the characterization of an agreement as “relevant” or whether a variation has rendered an agreement non‑relevant would be matters of contractual and statutory construction and therefore potential subjects of litigation.

• Administrative decision‑making. The Act requires the Minister to give a certificate to the Excise Minister where specified conditions are met (s 6(1)), and requires the Excise Minister to publish a Gazette notice (s 6(2)). Administrative decisions about whether conditions have been met, timing, the content of certificates, or the propriety of revocations under s 6(3) could be subject to judicial review under administrative law principles. The Act does not create its own internal review mechanism.

• Interaction with excise law and accounting entries. Section 7(1) states that prescribed petroleum exempt by virtue of s 6 shall not be taken to be excisable goods under the Excise Act 1901 and that any entry purporting to have been made under s 58 of that Act shall be taken not to have been made (s 7(1)). Disputes about whether an entry was properly made, whether excise has been overpaid or underpaid, or whether a repayment is carryable, could involve litigation or administrative dispute resolution channels available under excise and taxation laws.

What is not present in the supplied text

• No reported decisions, no case names, no citations. The supplied material does not contain references to decisions, litigation outcomes, or interpretative guidance from courts. There is no legislative note summarising precedents.

• No statutory dispute resolution procedure. The Act does not establish bespoke dispute resolution bodies or procedures for challenges to ministerial certificates or to the classification of petroleum. Any legal challenges would therefore be litigated within existing administrative, tax and constitutional law frameworks.

Implication for research

• To identify actual litigation history, one must consult legal databases, court reports, and administrative law records. The Act itself flags several plausible legal flashpoints , constitutional discrimination, the characterization of agreements as “relevant”, ministerial certification and revocation, and excise accounting entries , but the supplied text does not supply any litigation history or judicial interpretation. Any assessment of how courts have interpreted these provisions therefore requires external case‑law research beyond this statute text.

Several features of the statute create practical traps or points of operational uncertainty that parties negotiating agreements, producers, State governments and revenue officials should note. These are drawn directly from the statute’s wording and its interplay with other laws.

1. “Prescribed petroleum” is a narrower category than “petroleum” or “market petroleum” (s 3). The excise exemption applies only to “prescribed petroleum” as defined in s 3 (s 6(1)). That means producers cannot assume all hydrocarbons or derivative products are covered. Prescribed petroleum is limited to:

   • stabilised crude petroleum oil;
   • liquid petroleum obtained from naturally occurring petroleum gas; and
   • liquefied petroleum gas obtained from unstabilised crude petroleum oil or from naturally occurring petroleum gas (s 3). Products derived from petroleum that fall outside those definitions, or multi‑stage derivatives (which s 3’s definition of “market petroleum” specifically excludes), may not qualify.

2. Temporal precision matters: the 1 July date specified in the agreement is the entitlement trigger (s 5(a), s 6(1)(a)). Petroleum produced before that specified 1 July is excluded from the exemption (s 6(2)(a)). Parties must be careful when drafting and documenting the applicable 1 July date in the resource rent royalty agreement and in the revenue‑sharing agreement, because the Minister’s certificate and the Excise Minister’s Gazette declaration operate strictly from that date (s 6(1)-(2)).

3. The exemption ceases on revocation; revocation is ministerially driven and linked to the agreements’ continued force (s 6(3)-(4)). Section 3(3) creates a further gotcha: where an agreement is varied in a way that it ceases to be a “relevant” agreement it ceases to be in force for the purposes of this Act (s 3(3)(a)-(b)). A variation intended to be administrative could unintentionally remove the agreement’s “relevant” status and thereby trigger revocation of the excise exemption. Parties must therefore understand the Schedule definitions of “relevant” and control variations accordingly.

4. The production unit excludes refining and transport plant and facilities (s 3). If a producer’s operations straddle upstream production and downstream refining or transport, the exemption will not extend to plant and facilities used for refining or transport. That matters for planning and for accounting separation of activities.

5. Entries under s 58 of the Excise Act are treated as not having been made (s 7(1)). The Act takes the unusual step of saying that an entry purporting to have been made under s 58 shall be taken not to have been made, for exempted prescribed petroleum. That can affect record reconciliation and refund processes; parties should ensure administrative entries align with the Gazette declaration period to avoid confusion, and be prepared for retrospective adjustments with no interest entitlement (s 8).

6. No interest on repayments. Where excise amounts paid become repayable because of this Act, s 8 says no interest is payable on those amounts (s 8(1)). That creates a cashflow exposure for payors whose funds are refunded without interest. Parties should account for that in commercial negotiations and when assessing the timing of receipts and payments.

7. Departmental By‑laws remain relevant. Section 7(2) preserves and permits Departmental By‑laws under the Excise Act and the Excise Tariff Act 1921 in respect of various production area definitions (s 7(2)(a)-(c), (ba)). Producers and States must therefore attend not only to s 6 declarations but also to any applicable by‑laws that define prescribed production areas or condensate and intermediate production areas.

8. Constitutional constraint on ministerial exercise. Section 4 prevents the Commonwealth or the Minister from exercising powers under the Act or a relevant revenue‑sharing agreement in a way that discriminates between States or gives preference to one State over another (s 4). That means the Commonwealth cannot structure the revenue‑sharing arrangements or the exercise of powers in a way that would contravene those constitutional prohibitions. Parties should be cautious of any arrangements that differentiate treatment among States in a way that could be challenged as discriminatory or preferential.

9. Missing Schedules in the supplied text. The definitions of the “relevant” agreements depend on Schedule 1 and Schedule 2, which are not included in the text supplied here (s 3). That omission is a practical “gotcha” for anyone attempting to apply the Act without consulting the full statute. The Schedules are likely to contain the operative thresholds and precise contractual descriptors that determine whether an agreement is “relevant”.

10. Ministerial discretion versus obligation. Section 5 uses “may arrange” for the Minister’s power to arrange Commonwealth entry into a revenue‑sharing agreement upon state request (s 5). In contrast, s 6(1) uses “shall give” the certificate once the required agreements are in place (s 6(1)). Practitioners should observe that while the Minister can decline to arrange entry under s 5 in some circumstances, once the Commonwealth has entered a relevant revenue‑sharing agreement and the State and producer have the relevant resource rent royalty agreement, the Minister has a mandatory duty to issue the certificate under s 6(1).

These points should be carefully managed contractually and administratively. The statutory text allocates significant operational consequences to drafting and procedural sequencing: classification of product, dating of production, preservation of the “relevant” status of agreements, and adherence to by‑laws and excise accounting practices.

Compliance with the Act requires coordinated action by States, producers and Commonwealth officials to ensure the contractual and administrative prerequisites are met, and careful operational practices by producers to segregate and document production and plant activities. The following compliance checklist maps statutory steps to practical actions, with section citations.

1. Confirm product eligibility

   • Determine whether the petroleum produced is “prescribed petroleum” within the meaning of s 3. The exemption applies only to stabilised crude petroleum oil, liquid petroleum from naturally occurring petroleum gas, and LPG obtained from unstabilised crude or naturally occurring petroleum gas (s 3; s 6(1)). If the product does not fall within those categories, it is not eligible for the excise exemption under this Act.

2. Ensure the existence and form of the State-producer agreement

   • Enter into a relevant resource rent royalty agreement between the State and the producer(s) that provides for a royalty in respect of market petroleum produced from the production unit on or after the 1 July specified in the agreement (s 5(a), s 6(1)(a)). Carefully draft the agreement to meet the definitions set out in Schedule 1 (which must be consulted), and ensure the specified 1 July date is explicit and unambiguous.

3. State requests Commonwealth participation and Commonwealth response

   • The State should request the Commonwealth to enter into a relevant revenue‑sharing agreement (s 5(b)). The Minister then has the discretion to arrange Commonwealth entry into that agreement (s 5). Parties should document the State’s request and the Commonwealth’s actions to provide transparent evidence of the steps taken.

4. Enter into the Commonwealth‑State revenue‑sharing agreement

   • Once the Minister arranges for the Commonwealth to enter into the relevant revenue‑sharing agreement, ensure the revenue‑sharing agreement precisely matches any conditions necessary to cause the Minister’s certificate duty under s 6(1) to take effect. The content of the revenue‑sharing agreement should be consistent with Schedule 2 (s 3). Record dates and terms carefully.

5. Ministerial certification and Gazette declaration

   • When both the resource rent royalty agreement and the revenue‑sharing agreement are in place, the Minister must give the Excise Minister a certificate in writing stating it is appropriate that prescribed petroleum produced from the production source on or after the specified 1 July should be exempt from duties of Excise (s 6(1)). Ensure the Minister’s certificate sets out the production source and the specified 1 July date explicitly.
   • Monitor the Gazette for the Excise Minister’s declaration under s 6(2). The Excise Minister’s declaration is the operative instrument that causes the excise exemption to have legal effect for excise law purposes (s 6(2)).

6. Administrative record‑keeping and segregation of activities

   • Producers must maintain contemporaneous records identifying:
     • production source and production unit details (s 3);
     • precise dates of production for each batch or production run to determine whether production occurred on or after the specified 1 July and before any revocation (s 6(2));
     • product classification showing that output is “prescribed petroleum” as defined (s 3).
   • Ensure plant and facilities used in refining or transport are kept and accounted for separately since the production unit excludes such plant and facilities (s 3). This distinction affects whether the exemption applies.

7. Address entries under the Excise Act

   • If entries under s 58 of the Excise Act 1901 were made prior to the s 6 declaration, be prepared for the statutory fiction that such entries shall be taken not to have been made in relation to exempted prescribed petroleum while the s 6 declaration is in force (s 7(1)). Reconciliation of accounts with excise administrators is necessary.

8. Handling repayments

   • Where excise amounts are repayable because of the operation of the Act, understand that no interest is payable on those repayments by virtue of s 8(1)-(2). Budgetary and cashflow implications should be factored into financial planning.

9. Monitor agreement validity and variations

   • Section 3(3) provides that a relevant agreement that is varied so as to cease to be relevant ceases to be in force for the purposes of the Act (s 3(3)). Avoid unilateral or inadvertent variations that might render an agreement non‑relevant. Where variations are contemplated, obtain legal advice to ensure the agreement remains “relevant” as described in the Schedules.

10. Observe constitutional and non‑discrimination constraints

• Ensure that any exercise of powers under the Act or under a relevant revenue‑sharing agreement complies with s 4’s non‑discrimination and non‑preference requirements as measured against paragraph 51(ii) and s 99 of the Constitution. Contract terms and ministerial actions should be reviewed for state‑by‑state parity and for any practical effects that might be classified as preferential treatment between States (s 4).

11. Comply with Departmental By‑laws and Excise Tariff definitions

• Check relevant Departmental By‑laws preserved or allowed under s 7(2) and the Excise Tariff Act 1921 definitions referenced therein (s 7(2)). Those by‑laws may prescribe production areas, new production areas, condensate production areas, and intermediate petroleum production areas that affect applicability.

12. Prepare for revocation contingencies

• If either the resource rent royalty agreement or the revenue‑sharing agreement ceases to be in force, the Minister must certify to the Excise Minister that the declaration should be revoked and the Excise Minister must revoke it by Gazette notice (s 6(3)-(4)). Producers should maintain contingency plans for the reinstatement of excise liabilities and for administratively reclassifying product post‑revocation.

13. Seek legal and tax advice

• Given the interplay with excise law, the potential constitutional constraints, and the dependence on Schedules for the definition of “relevant” agreements, parties should obtain legal and tax advice when negotiating agreements and before taking administrative steps to invoke the Act’s mechanism.

Following these steps will align practical actions with the statutory requirements in ss 3-8 and will help manage the administrative sequencing (agreement formation, State request, Ministerial arrangement, certificate, Gazette declaration, and ongoing compliance). The Act’s limited relief to payors in relation to interest on repayments (s 8) means that financial and cashflow planning should be part of the compliance process.
