Excise By-law No. 127

The central legal concept deployed by this instrument is the administrative classification of specific petroleum fields as “onshore fields” for the narrow legal reference in paragraph (a) of the definition of “onshore field” in subsection 3(1) of the Excise Tariff Act 1921 (cl 3). The by-law therefore operates as a definitional device rather than as a primary taxing instrument. It does not itself levy excise, nor does it set rates, exemptions, procedural rules, or penalties. Its purpose is to locate particular fields within the pre-existing statutory structure of excise and tariff law by updating the list of fields that attract the consequences that follow from being an “onshore field”.

Key elements and concepts visible in the text:

• Delegated rule-making: the instrument is made “pursuant to section 165 of the Excise Act 1901” (preamble). That identifies the constitutional mechanism: a statutory delegation to the executive (or its delegate) to make by-laws that have legal effect in the excise/tariff regime.
• Temporal specification: the by-law contains a commencement provision (cl 2) that fixes when the instrument itself becomes operative, and separately records “first commercial production” dates for each field (cl 2 and the tables). Those dates are presented as factual markers relevant to the legal status of the field as an “onshore field”.
• Specificity of scope: fields are listed by name and grouped by geological basins (Carnarvon, Canning, Perth, Bowen/Surat, Cooper/Eromanga (QLD and SA sections), Amadeus) (cl 3). Some entries include state identifiers (e.g. “COOPER/EROMANGA BASIN (QLD)” and “(SA)”), indicating the by-law treats geographic boundaries and field identities as legally significant.
• Supersession: cl 4 repeals Excise By-law No. 115, so this instrument replaces the earlier schedule as the operative list for the specified statutory purpose.

Because the by-law expressly limits its effect to the paragraph (a) definition in s 3(1) of the Excise Tariff Act 1921, the key legal operation is classificatory: it determines which physical extraction sites fall within the statutory category that the tariff/excise law addresses. Any downstream legal consequences flow from that classificatory change via the parent statutes, not from the by-law text itself.

This by-law principally affects persons and entities engaged in petroleum extraction, production, or first commercial production activities in the particular named fields. By prescribing those fields as “onshore fields” for paragraph (a) of the definition contained in subsection 3(1) of the Excise Tariff Act 1921, the instrument changes which sites are treated under that act’s onshore-field rules (cl 3). The immediate practical parties affected will include:

• field titleholders, operators and joint ventures that own or operate the fields listed in the schedule;
• downstream purchasers and processors who acquire product identified as originating from an “onshore field”, insofar as tariff/excise provisions differentiate treatment by point or place of production;
• advisers (tax lawyers, accountants, customs brokers) who must interpret whether an activity or product originates in a listed field and therefore falls within the onshore-field definition; and
• Customs and revenue administration functions charged with assessing excise/tariff consequences, because the by-law is the administrative instrument that signals which fields they must treat as onshore for the referenced statutory provision (preamble and cl 3).

The by-law does not itself impose licences, reporting formats, or payment obligations; those are set out in the parent statutes. However, the practical incidence of excise charges, tariff obligations, or other statutory obligations that depend on onshore/offshore classification will fall, in practice, on the commercial entities engaged in production and sale of petroleum from the prescribed fields. The by-law records for each field a “first commercial production” date (cl 2 and the tables). That dating can affect the temporal application of any statutory provisions that depend on when production began, and therefore may affect entities’ historical liability or eligibility under schemes in the Excise Tariff Act 1921. Finally, the repeal of Excise By-law No. 115 (cl 4) may affect parties who previously structured compliance or contractual arrangements on the basis of that earlier instrument, because the operative legislative list has changed.

The by-law itself articulates few operational duties or express rights; its legal mechanics are primarily classificatory. The direct duties and rights arising from this instrument are therefore largely derivative: they are the duties and rights that the Excise Act 1901 and the Excise Tariff Act 1921 attach to the status “onshore field”. The by-law creates a right to treat a named physical location as an onshore field for the one statutory reference specified, and it places the named fields within the scope of whatever duties that classification causes under the parent statutes.

Concrete, text-supported points:

• Delegation and exercise of power: a person acting as “delegate of the Chief Executive Officer of Customs” exercised authority under s 165 of the Excise Act 1901 to make the by-law (preamble). That identifies who had the legal power to act and therefore the procedural legitimacy of the instrument.
• Classification duty to administrators: by prescribing fields in cl 3, the by-law places an administrative duty on Customs and any agency tasked with applying the Excise Tariff Act 1921 to accept and apply that classification when administering paragraph (a) of the s 3(1) definition (cl 3). The by-law is the administrative source for that classification.
• Rights for affected entities: operators and other market participants can rely on the by-law to determine whether the statutory onshore-field rules apply to their field; the instrument provides a public, enumerated list and first-production dates to support that legal determination (cl 2, cl 3).
• No procedural instructions: the by-law does not set out registration, reporting, invoicing, payment, exemption, or accounting procedures. It therefore creates no standalone obligations of that type; any such duties must be sought in the parent Acts and subordinate regulations they authorise.

Because the by-law is narrowly framed, the bulk of operative duties and rights (duty to pay excise, right to any concessions, obligations to keep records, enforcement mechanisms) will be supplied by reference to the Excise Act 1901 and the Excise Tariff Act 1921 rather than by the by-law text itself.

Excise By-law No. 127 does not itself prescribe penalties, enforcement actions, or adjudicative processes. The instrument is a classificatory schedule; it identifies fields as “onshore fields” for a defined statutory purpose (cl 3) and repeals a prior by-law (cl 4). The by-law is made under s 165 of the Excise Act 1901 (preamble), and enforcement of obligations that attach to being an onshore field will therefore be undertaken under the enforcement regimes, penalty provisions, and procedural powers contained in the Excise Act 1901 and the Excise Tariff Act 1921. Because those underlying statutes are not reproduced within this by-law, the by-law itself provides no new or distinct penalty apparatus.

Practical consequences and implementation considerations drawn from the instrument:

• Enforcement locus: administrative enforcement responsibility remains with the agencies that administer the Excise Act 1901 and the Excise Tariff Act 1921. The by-law functions as an authoritative classification reference that those agencies use when applying their enforcement powers against activities or persons affected by onshore-field rules (preamble; cl 3).
• No independent sanctioning power: no clause in the by-law establishes sanctions, pecuniary penalties, or specific offences arising from breach of the by-law itself; any sanctionable conduct will be that which the parent statutes identify as non-compliant for persons operating in onshore fields.
• Evidentiary role: the by-law’s schedules and recorded “first commercial production” dates may be used by administrators and the courts (where relevant) as evidence of when a field became legally an “onshore field” for purposes of the Excise Tariff Act 1921, which can affect the period over which enforcement activity is pursued. However, cl 2 fixes the date when the by-law takes effect (31 January 1998), so there is an interplay between the by-law’s effective date and the historical production dates listed for each field that administrators will need to interpret in the context of the parent Acts.

Because the by-law defers substantive enforcement to the parent statutes, any practitioner assessing penalty risk must consult the Excise Act 1901 and the Excise Tariff Act 1921 for the statutory enforcement and penalty regime applicable to activities classified by this instrument.

The by-law explicitly anchors its legal effect to two pieces of primary legislation: the instrument is made pursuant to section 165 of the Excise Act 1901 (preamble), and it prescribes fields as “onshore fields” for the purposes of paragraph (a) of the definition of “onshore field” in subsection 3(1) of the Excise Tariff Act 1921 (cl 3). The interaction is therefore classificatory and derivative: this instrument modifies how the primary statutes are to be applied by altering the factual inputs those statutes require.

Concrete interaction points:

• Delegated instrument under the Excise Act 1901: the by-law is within the delegated powers authorised by s 165 of the Excise Act 1901. That creates a hierarchical legal relationship: the by-law is subordinate legislation made under the enabling Act (preamble).
• Definition modification for the Excise Tariff Act 1921: cl 3 places specified fields within the category “onshore field” for paragraph (a) of the s 3(1) definition in the Excise Tariff Act 1921. Any provision in the Tariff Act that applies differently to onshore and offshore fields will operate on the fields listed as if they were onshore, to the extent that paragraph (a) and the rest of s 3(1) create such distinctions (cl 3).
• Repeal of prior list: cl 4 repeals Excise By-law No. 115. That means that where the earlier by-law previously defined or listed fields for the same statutory purpose, this instrument replaces that instrument as the operative classification. The practical effect is a single consolidated operative schedule, but the by-law itself contains no transitional provisions; the repeal is expressed without detailed savings or transitional clauses (cl 4).
• Temporal layering: the by-law’s own commencement date is 31 January 1998 (cl 2), but the schedule records “first commercial production” dates for each field, many of which predate 1998 (cl 2 and the tables). The interaction between those recorded first-production dates and any time-sensitive provisions in the parent Acts (for example, provisions that apply only after the first commercial production date, or that establish offsets or concessions tied to the start of production) will require interpretation across the instruments; the by-law supplies the factual dates but not the legal consequences, which remain in the relevant statutory provisions.

Absent from the by-law are cross-references to other potentially relevant instruments (state petroleum legislation, customs procedures, excise refund schemes, or administrative practice directions). Any such cross-system implications must be traced by consulting the Excise Act 1901 and the Excise Tariff Act 1921 and any subordinate instruments they authorise.

The by-law text provides a minimal amendment narrative within itself. The instrument was made on 29 January 1998 by a named delegate of the Chief Executive Officer of Customs (preamble). It contains an explicit commencement provision: the by-law “shall take effect on and from 31 January 1998” (cl 2). The only express change to prior subordinate legislation recorded in the instrument is the repeal of Excise By-law No. 115 (cl 4).

From the by-law’s own content the following amendment-history facts can be stated:

• Creation: made and dated 29 January 1998, signed by the delegate (preamble).
• Commencement: took legal effect on 31 January 1998 (cl 2).
• Repeal: Excise By-law No. 115 repealed (cl 4). The by-law does not provide text of the repealed instrument or state whether the current schedule is intended merely to update the earlier one or to effect more substantive change in classification; it only effectually replaces the earlier by-law’s operative schedule for the specified statutory purpose.

The instrument does not record prior amendments to itself, nor does it include a schedule of amendments, savings provisions, or transitional arrangements beyond the single repeal clause. No subsequent amending by-laws or consolidated versions are referenced in the text. If a practitioner needs a full legislative history of how the list of onshore fields has evolved over time, that history is not contained within this instrument and must be obtained from the statutory register or archival records of by-laws and orders made under the Excise Act 1901 and the Excise Tariff Act 1921.

The by-law itself does not include nor reference any litigation. The instrument does not identify any judicial or administrative decisions that interpret its operation, and it names no cases. Therefore, within the four corners of this text, there is no litigation history recorded.

Implications for practitioners:

• No judicial construction recorded in the instrument: because the by-law contains no reference to case law or disputes, any legal questions about interpretation (for example, whether a particular geographic feature or production unit falls within a listed field name, or how the recorded first-production dates interact with statutory timing provisions) would need to be litigated or administratively resolved, drawing on the parent Acts and general principles of statutory interpretation.
• Evidentiary reliance: the by-law provides a public, statutory record of the fields and their first-production dates, which would function as primary evidence in disputes about classification. Where the instrument’s entries are clear, administrators and courts would normally treat the by-law as decisive for the narrow question it addresses: whether a particular field is to be treated as an onshore field for paragraph (a) of s 3(1) of the Excise Tariff Act 1921.
• Absence of reported disputes in the text does not mean there have been none outside this instrument. The by-law does not attempt to summarise or list any decisions; it simply establishes the listing and the repeal of the earlier by-law. Any litigation relating to the classification issues that flow from this by-law will need to be located in judicial and tribunal records rather than in the instrument.

The by-law is short and tightly focused, but a range of practical and interpretive issues arise from its form and content. These are not policy conclusions but concrete risks and points of legal friction that the instrument itself creates or leaves unresolved.

1. Classification is narrow but consequential. The by-law prescribes fields “for the purposes of paragraph (a) of the definition of ‘onshore field’ in subsection 3(1) of the Excise Tariff Act 1921” (cl 3). That limited phrasing means the prescription affects application of that specific statutory provision; practitioners must confirm whether other statutory or regulatory tests for “onshore” use the same definition or require separate determinations. The by-law does not address those other potential regimes.

2. Timing and retrospective appearance. The by-law commences on 31 January 1998 (cl 2) but lists “first commercial production” dates that in many entries predate 1998 (cl 2 and the tables). The instrument does not itself state whether the recorded first-production dates create retrospective operation of the parent Acts, whether they merely record historical facts for future application, or whether they are determinative for the operation of time-sensitive provisions in the Excise Tariff Act 1921. That gap creates an interpretive question administrators and affected parties will need to resolve when applying the parent Acts’ time-dependent rules.

3. Reliance on precise naming and metadata. The legal effect turns on the field-names and the table entries (cl 3). Minor typographical issues in the schedule (for example, inconsistent date formats and a spacing error in “01.07.8 7” for McWhirter and other entries) could generate disputes over whether an intended field is included or whether a date is accurately recorded. The by-law contains no disambiguation mechanism for near-miss name variants, alternative local names, or boundary disputes.

4. Repeal without transition details. The instrument repeals Excise By-law No. 115 (cl 4) but includes no express savings clause or transitional provision for liabilities, returns, or administrative steps begun under the earlier by-law. Where parties structured reporting, exemptions, or contractual obligations around the earlier instrument, the absence of transitional rules may generate operational friction.

5. Absence of procedural detail. The by-law does not set out administrative processes, notification obligations, recordkeeping, or interaction with customs/tax administrative systems. It is a declarative list. Practitioners who look to the by-law for practical guidance on how to comply, register, or seek clarifications will need to consult the parent Acts and administrative instruments to identify the processes that now apply to the fields once they are treated as onshore.

6. Delegated decision-making creates administrative centrality. The instrument was made by a delegate of the Chief Executive Officer of Customs pursuant to s 165 of the Excise Act 1901 (preamble). That indicates that the classification mechanism sits within executive administrative power; disputes about the exercise of that delegated power would engage principles concerning the scope of the delegate’s authority as conferred by s 165, but the by-law contains no procedural record of consultation or criteria used in selection.

7. Geographic and jurisdictional cross-cutting. The schedule includes basin headings with state annotations (for example, Cooper/Eromanga BASIN (QLD) and (SA)) and fields across multiple states and territories (cl 3). Practitioners must map the by-law’s list to state-level licences, environmental approvals and title delineations to avoid double counting or misclassification of producing units.

These points are concrete interpretive and operational risks that arise from the text and structure of the by-law itself; resolving them requires attention to administrative guidance and to the relevant provisions of the Excise Act 1901 and the Excise Tariff Act 1921.

The by-law is a classificatory instrument; compliance therefore takes the form of adapting business and administrative practices to the fact that certain fields are now prescribed as “onshore fields” for the specified statutory purpose. The by-law itself contains no registration or reporting steps, so compliance requires translating the by-law’s classification into the operational obligations that the Excise Act 1901 and the Excise Tariff Act 1921 impose.

Practical compliance steps grounded in the by-law’s mechanics:

1. Confirm field inclusion. Operators and titleholders should check the by-law’s schedule (cl 3) to confirm whether the field names under which they operate are listed. Because the list is the administrative source for the onshore-field classification, it is the primary reference for deciding whether parent-act obligations apply.

2. Note the recorded first commercial production date. The by-law records a “first commercial production” date against each field name (cl 2 and the tables). Parties should record and reconcile that date with their internal production records. If there is a discrepancy between the by-law date and the operator’s internal records, flag it immediately with Customs or the administering authority because the by-law’s date could be used in interpreting statutory timing rules.

3. Map obligations under the parent Acts. Once a field is confirmed as listed, determine which duties, concessions, reporting obligations, or registrations in the Excise Act 1901 and the Excise Tariff Act 1921 apply to operations from that field. The by-law does not specify those duties (the classification is limited to the paragraph (a) reference in s 3(1) of the Tariff Act), so operators must consult the parent statutes and any subsidiary regulations or administrative rulings to identify:

   • excise or tariff liabilities that apply to products originating from onshore fields;
   • registration or licensing requirements for producers of excisable products;
   • record-keeping, invoice and marking rules for origin and excise accounting;
   • refund, rebate or concession schemes that are conditional on field status or production dates.

4. Review historical treatment and transitional exposure. Because many recorded first-production dates predate the by-law’s commencement (cl 2 and the tables), operators should assess whether prior periods might be open to review by the revenue authority. That assessment requires checking the temporal extent of any excise/tariff rules that attach to the onshore-field classification and determining whether past production was treated differently.

5. Rectify or clarify ambiguities. If the by-law’s schedule contains ambiguous field names, typographical errors or inconsistent date formats (visible in the schedule text), operators should seek written clarification from the administering agency (Customs or the relevant revenue authority). Reliance on the public schedule is the safer course, but where ambiguity could cause material tax exposure, obtain administrative confirmation in writing.

6. Update contracts and commercial arrangements. Where commercial contracts, sale agreements, or joint-venture arrangements depend on a field’s onshore/offshore status (for price, tax-sharing, or accounting), amend or note contractual provisions to reflect the field’s listing and the recorded first-production date. The by-law’s repeal of the prior instrument (cl 4) may affect contractual clauses that explicitly referenced By-law No. 115.

7. Keep administrative footprints defensible. Maintain contemporaneous records showing when operators first became aware of the by-law and what steps they took to comply (internal notices, communications with Customs, adjustments to returns). Because the by-law itself is a public instrument, administrators will treat reliance on it as reasonable where steps to comply are documented.

In all these steps, the by-law functions as the declaratory trigger: it supplies the authoritative list and dates (cl 2-3). The specific operational obligations and the technical compliance mechanics are those in the Excise Act 1901 and the Excise Tariff Act 1921 and their subordinate instruments; therefore, compliance requires active coordination between the by-law’s classification and the substantive provisions and administrative practice set out under those Acts.
