The Act revolves around several core concepts that define its operational scope. The first is the distinction between retail sale and wholesale sale. Section 4(1) defines retail sale as a sale in a retail quantity for purposes of use or consumption. Section 4A(1) sets the retail quantity threshold at not more than 3 000 litres, or a different amount if prescribed by regulation. However, a quantity is not a retail quantity unless delivered at a fixed site by a metered pump into either the running tank of a vehicle or a container with a capacity of less than 250 litres (section 4A(2)). Any sale exceeding that threshold, or not meeting the delivery conditions, is wholesale. This distinction matters because the licence must be appropriate to the type of sale: a retail licence authorises retail sales only, and a wholesale licence authorises wholesale sales only.

Eligible petroleum products are defined as petroleum products on which Commonwealth customs or excise duty has been paid or is payable, but do not include products prepared by mixing duty-paid with non-duty-paid products. This concept feeds into licence conditions set under section 11(2)(gb), which may require terms in contracts between manufacturer or importer licensees and purchasers regarding the timing of payment for the duty component of the sale price.

Periods of restriction and rationing periods are central to Part 5. A period of restriction is declared by proclamation, lasts up to seven days initially, and may be extended but not beyond 28 days unless Parliament approves. The Governor may also declare that the period of restriction is a rationing period, and may specify which kinds of petroleum products are rationed products. During a rationing period, no person may sell or purchase rationed petroleum products except to or by a permit holder, with an exception for ordinary course sales by petroleum product business operators (section 35(3)). Permits under section 36 may be subject to conditions, including quantity limits, coupon systems, and a requirement that the permit holder carry the permit when driving a vehicle supplied under the permit.

The Act also defines an authorised officer as a person appointed by the Minister, plus all police officers and authorised officers under the Taxation Administration Act 1996 (section 42(4)). These officers have broad powers under section 44: to enter and inspect premises, use reasonable force with a warrant or in exigent circumstances, require production of records (including computer records in understandable form), examine and copy records, take photographs and recordings, require persons to state their name and address, and ask questions. There is a specific power to require an occupier to give reasonable assistance (section 44(4)). The Act provides that self-incrimination is not an excuse for failing to answer questions or produce records, but the answer or the fact of production (as distinct from the contents) is not admissible in proceedings other than under the Act (section 46).

Notional sale and purchase is a concept enabled by section 4D: the regulations may declare that a sale and purchase is taken to occur in specified circumstances where petroleum products are delivered or allocated for sale or consumption. This is a mechanism to capture transactions that might not otherwise meet the ordinary definition of sale.

The licence itself is a key legal instrument. Licences expire two years after issue (section 10(2)). They are not transferable except by way of variation under section 12. The Minister may cancel or suspend a licence if satisfied the licensee has contravened or failed to comply with the Act, or if other sufficient cause exists (section 18). Conditions may be fixed by the Minister, including limitations on premises, sales, record-keeping, and compliance with Part 5 or regulations.

The Act primarily affects any person or entity involved in the sale of petroleum products in South Australia. This includes operators of petrol stations, fuel distributors, wholesalers, and any business that sells motor spirit, diesel fuel, or liquefied petroleum gas. The licensing requirement in section 8 applies to both retail and wholesale sellers, so anyone who engages in such sales must hold a licence. This includes not only traditional service stations but also other entities that sell petroleum products, such as agricultural supply businesses, marine fuel suppliers, and fleet operators that sell to third parties. The definition of sale under Part 5 (section 32) includes barter, exchange, and offers to sell, so the Act captures transactions beyond simple cash sales.

During periods of restriction or rationing, the Act affects a much broader population: all persons who purchase or use petroleum products in the State. During a rationing period, no person may purchase rationed petroleum products without a permit, subject to the exemption for ordinary course sales by petroleum product businesses. This means motorists, businesses, farmers, and government entities would all require permits to acquire rationed fuels. The Minister must give special consideration to the needs of those living in country areas when exercising powers under Part 5 (section 39), acknowledging that rural residents are likely to be disproportionately affected by fuel shortages.

The Act also affects persons who transport petroleum products in bulk (quantities exceeding 3 000 litres) by road within the State: they must carry prescribed records in the vehicle at all times while transporting (section 52). This applies to fuel tanker drivers and their employers. Any person carrying on a business involving or related to petroleum products must keep prescribed records for five years (section 53). This includes not only licensees but also other businesses in the supply chain, such as storage operators or brokers, though the Minister may exempt classes of persons or products under section 6.

The Act affects persons who hold information about petroleum product dealings: the Minister or Commissioner may require any person who is or was concerned in a petroleum-related business to furnish information in writing (section 51). This power extends to agents and employees of such persons. Authorised officers may require any person suspected of contravening the Act to state their name and address, and may require any person with knowledge of relevant matters to answer questions (section 44(1)(j)-(k)). These powers affect a wide range of individuals beyond the regulated industry.

The Act also applies to persons who make false claims about holding a licence or permit: section 53A makes it an offence to falsely claim or purport to be the holder of a licence or permit, with a maximum penalty of $10 000. This protects the integrity of the licensing system and affects any person who might misrepresent their authorisation.

Finally, the Act affects persons involved in its administration: the Minister, the Commissioner of State Taxation, authorised officers, and any person engaged in administration are subject to the confidentiality obligations in section 56, with penalties for unauthorised disclosure.

The Act imposes several core duties and confers specific rights on regulated persons and the authorities.

Duty to hold a licence: The foundational duty under section 8 is that no person may sell petroleum products by retail or wholesale unless authorised by a licence. This is an absolute prohibition with a maximum penalty of $10 000. The licence must be appropriate to the type of sale (retail or wholesale). A licensee must not contravene a condition of the licence (section 17), with the same penalty.

Duty to comply with directions during periods of restriction: Section 34(6) makes it an offence to contravene or fail to comply with a direction issued by the Minister during a period of restriction. The maximum penalty is $250 000 for a body corporate and $10 000 for a natural person. This is a significant obligation that can include price controls and sales prohibitions. Directions may be issued to a particular person, a class of persons, or the public generally via Gazette or newspaper notice.

Duty to comply with permit conditions: During a rationing period, permit holders must comply with conditions of their permit, including carrying the permit when driving a vehicle supplied under the permit (section 36(4)-(5)). The maximum penalty is $250 000 for a body corporate and $10 000 for a natural person. On cancellation, the former permit holder must return the permit to the Minister (section 36(7)).

Record-keeping duties: Section 53 requires any person carrying on a petroleum-related business to keep accounts, invoices, receipts, records, books and documents as required by the Minister for five years after the last entry. The maximum penalty is $2 500 with an expiation fee of $200. Bulk transporters must carry prescribed particulars while transporting non-retail quantities (section 52). Persons who purchase under a bulk end user certificate (issued before Part 2A was repealed) must also keep invoices for five years.

Duty to provide information: Under section 51, the Minister or Commissioner may require any person who carries on or has carried on a petroleum-related business, or their agents or employees, to furnish information in writing. Failure to comply is an offence with a maximum penalty of $5 000. Information may be required to be verified by statutory declaration (section 55). The Act also prohibits providing false or misleading information (section 54).

Duty to not hinder authorised officers: Section 45 creates offences for hindering, obstructing, using abusive language, refusing to comply with requirements or directions, refusing to answer questions, or falsely representing oneself as an authorised officer. The maximum penalty is $5 000.

Right to review: Section 47 confers a right to seek review by the South Australian Civil and Administrative Tribunal (SACAT) for certain decisions: refusal to issue, renew, or vary a licence; refusal to issue a permit; decisions to vary, suspend, or cancel a licence; and decisions to cancel a permit. Applications must be made within one month of receiving notice of the decision, or within one month of receiving written reasons if reasons were not given at the time of the decision. Decisions to vary, suspend, or cancel a licence or cancel a permit are suspended pending review (section 47(5)). The Minister must give written reasons on request (section 47(2)). Except for these review rights, section 37 prevents proceedings against the Minister to compel or restrain action under Part 5.

Right to compensation: Section 34(8) provides that the Minister may, if of the opinion that it is just to do so, compensate a licensee or person who has incurred expenses in complying with a condition or direction under that section. This is discretionary, not a right.

Right to rely on insurance: Section 38(2) provides that if a person conforms with published conservation principles during a period of restriction and thereby breaches an insurance policy, that breach is to be disregarded for determining rights under the policy.

The Act establishes a graded penalty framework. The most serious penalties apply to offences during periods of restriction and rationing. Under section 34(6), contravening a direction during a period of restriction carries a maximum penalty of $250 000 for a body corporate and $10 000 for a natural person. Identical penalties apply under section 35 for selling or purchasing rationed petroleum products without a permit during a rationing period, and under section 36(5) for a permit holder contravening a permit condition. For a natural person, $10 000 is the maximum penalty for most substantive offences, including selling without a licence (section 8) and breaching a licence condition (section 17). For record-keeping offences under sections 52 and 53, the maximum penalty is $2 500, and each carries a $200 expiation fee, indicating they are treated as minor regulatory offences. Hindering an authorised officer under section 45 attracts a $5 000 maximum penalty. Falsely claiming to hold a licence or permit under section 53A carries $10 000.

The Act contains several special enforcement mechanisms. Section 60 provides for continuing offences: if an offence involves a continuing act or omission, the person is liable to an additional daily penalty of up to one-tenth of the maximum penalty for each day the contravention continues. If the act or omission continues after conviction, the person commits a further offence. Section 60(2) clarifies that for omissions, the contravention continues for as long as the required act remains undone after the compliance period.

Prosecutions are subject to constraints. Section 61 requires the Minister's consent to commence any prosecution. An apparently genuine certificate purporting to be the Minister's consent is proof of that consent absent proof to the contrary (section 61(3)). For expiable offences (those carrying an expiation fee), proceedings must be commenced within the time limits prescribed by the Summary Procedure Act 1921. For all other offences, proceedings must be commenced within two years of the date of the alleged offence, or with the Minister's authorisation up to five years after that date. This is a longer limitation period than many summary offences, reflecting the complexity of investigating petroleum product transactions.

The Act also provides for evidentiary presumptions that ease the prosecution's burden. Section 62 sets out that a certificate from the Minister certifying matters such as whether a person was an authorised officer, held a licence or permit, whether a period of restriction was in force, or whether a substance is a petroleum product of a specified kind, is proof of those matters in the absence of proof to the contrary. Section 62(2) establishes a conclusive presumption: if a vending machine from which petroleum products may be obtained is present on premises, the occupier is taken to have sold petroleum products by that machine unless a licensee is authorised by licence to sell via that machine. This reverses the burden of proof on the occupier.

The defence under section 57 provides a statutory defence: the defendant must prove the offence was not committed intentionally and did not result from any failure to take reasonable care. This is a reverse onus defence, meaning the defendant bears the legal burden on the balance of probabilities. It is available for all offences under the Act, though it is not available if the offence provision expressly excludes it. The availability of this defence means that even strict liability offences can be defended by showing a lack of intent and reasonable care.

Section 7(1) expressly provides that the provisions of this Act are in addition to and do not derogate from the provisions of any other Act. This means the Act operates alongside other South Australian legislation, and compliance with this Act does not excuse non-compliance with other Acts, nor does this Act override other Acts unless specifically provided. For example, a person selling petroleum products must also comply with the Environment Protection Act 1993 (which was amended by this Act) regarding storage and handling of fuels, local council planning laws, the Work Health and Safety Act 2012, and the Fair Trading Act 1987 regarding consumer protections. The Act does not replace those obligations.

The Act interacts closely with Commonwealth taxation legislation. The definition of eligible petroleum products in section 4(1) refers to petroleum products on which Commonwealth customs or excise duty has been paid or is payable. The definitions of Commonwealth customs duty and Commonwealth excise duty refer to the Customs Tariff Act 1995 and the Excise Tariff Act 1921 of the Commonwealth, or other prescribed Commonwealth legislation. Section 4(2) clarifies that references to Commonwealth Acts include those Acts as amended or substituted. Licence conditions under section 11(2)(gb) may require terms in contracts concerning the timing of payment of the duty component of the sale price. This creates a direct regulatory link between the State licensing scheme and Commonwealth duty payments, likely to ensure that duty is passed through appropriately and not used as a financing tool.

The Act recognises corresponding laws of other States and Territories. Section 4(1) defines a corresponding law as a law of another State or Territory declared by regulation to be a corresponding law. Section 64(2a) allows regulations to authorise powers under this Act to be exercised for the purposes of administering or enforcing a corresponding law. This contemplates mutual assistance between jurisdictions, for example where an authorised officer under the South Australian Act might exercise powers to assist an investigation in another State. Section 56(2)(c) permits disclosure of information in connection with the administration or enforcement of a corresponding law.

The Act interacts with the South Australian Civil and Administrative Tribunal Act 2013. Section 47 provides for review of certain decisions by SACAT, and section 34 of the SACAT Act governs the review process. Transitional provisions from the Statutes Amendment (SACAT No 2) Act 2017 moved the review function from the District Court (Administrative and Disciplinary Division) to SACAT, so any existing right to appeal to the District Court before 22 February 2018 was converted to a right to seek review by SACAT. The SACAT Act also applies to evidentiary and procedural matters for reviews.

The Act interacts with the Taxation Administration Act 1996. Section 42(4) provides that all authorised officers under the Taxation Administration Act 1996 are automatically authorised officers for the purposes of this Act. This aggregates enforcement resources. The Commissioner of State Taxation is defined in section 4(1) to include the Commissioner of State Taxation and any Deputy Commissioner, and the Minister may delegate powers to the Commissioner under section 49. This suggests the Commissioner plays a role in administering certain aspects of the Act, particularly regarding information powers under section 51.

The Act also interfaces with the Corporations Act 2001 (Cth) for service of documents. Section 63(2)(b) allows service on a company or registered body in accordance with sections 109X or 601CX of the Corporations Act. The Act also references the repealed Part 2A (bulk end user certificates and subsidies) which was deleted by the Statutes Amendment (Budget 2010) Act 2010, but transitional provisions preserve existing rights and obligations under that Part.

The Act has been amended frequently since its commencement on 1 July 1995. The original Act repealed three earlier Acts: the Business Franchise (Petroleum Products) Act 1979, the Motor Fuel Distribution Act 1973, and the Petroleum Shortages Act 1980. This consolidation simplified the regulatory framework into a single Act.

The most significant structural amendment was the Petroleum Products Regulation (Licence Fees and Subsidies) Amendment Act 1998, which came into operation on 1 May 1998. This amendment deleted references to annual and monthly licences, introduced the concepts of retail and wholesale licences, inserted definitions for eligible petroleum products, Commonwealth customs duty, and Commonwealth excise duty, and introduced Part 2A dealing with bulk end user certificates and subsidies. It also inserted sections 4A to 4D defining retail quantity, notional sales, and other matters, and introduced record-keeping obligations.

The National Tax Reform (State Provisions) Act 2000 (commenced 8 June 2000) made changes consequential to the introduction of the Goods and Services Tax. It deleted the definitions of bulk end user certificate and off-road diesel fuel user certificate, and amended section 20 and related provisions. The Statutes Amendment (Petroleum Products) Act 2007 (commenced 1 July 2008) was a major simplification. It deleted numerous definitions that were no longer relevant (conveyance, dangerous situation, development authorisation, industrial pump, plant, prescribed retail sale, Retail Outlets Board). It substituted section 8 to simplify the licensing requirement, amended section 10 to fix the two-year licence term, deleted Parts 3, 4, 6, 7, and Schedules 1 and 3, which had contained detailed provisions about retail outlet boards, subsidies, and other matters. It also amended section 34(2) regarding controls during restriction periods.

The Statutes Amendment (Budget 2010) Act 2010 (commenced 1 January 2011) repealed Part 2A entirely, abolishing the bulk end user certificate and subsidy scheme. Transitional provisions preserved existing entitlements and repayment rights. The Act also made consequential amendments to sections 4, 8, 11, 44, 47, 50, 53, 53A, and 56 to remove references to Part 2A and update the definition of certificate for record-keeping purposes.

The Statutes Amendment (Directors' Liability) Act 2011 (commenced 1 January 2012) increased penalties in sections 34, 35, and 36 for body corporates for offences during restriction and rationing periods, setting the maximum at $250 000. The Statutes Amendment (SACAT No 2) Act 2017 (commenced 22 February 2018) substituted Part 9 on reviews to replace the District Court with SACAT as the review body, and inserted the definition of Tribunal in section 4(1). The Statutes Amendment and Repeal (Simplify) Act 2019 (commenced 3 October 2019) made minor amendments to sections 34(5) and 38(1) regarding modes of publication of notices and directions, allowing website publication as an alternative to Gazette or newspaper.

The Act's text does not contain references to any specific court cases. The legislative history and the Act itself do not name any judicial decisions. This is not uncommon for South Australian legislation, as the published Act typically does not include case annotations. However, it is possible that cases have been decided under the Act in the District Court (formerly the Administrative and Disciplinary Division) or SACAT regarding licensing decisions, permit refusals, or penalty matters. The transitional provisions from the 2017 SACAT amendments indicate that some proceedings were formerly heard in the District Court. Without access to case law databases, this deep dive cannot identify specific litigation outcomes. Practitioners should search the South Australian case law databases for decisions interpreting provisions such as the definition of retail quantity (section 4A), the scope of licence conditions, the meaning of other sufficient cause for licence suspension or cancellation under section 18, and the application of the general defence under section 57. The broad discretionary powers given to the Minister in issuing licences and permits, and the limited review rights under section 47, may have been challenged on administrative law grounds, but the Act itself does not record any such challenges.

Several provisions in the Act create traps for the unwary.

The retail quantity definition is narrower than expected. Under section 4A, even if a quantity does not exceed 3 000 litres, it is not a retail quantity unless it is delivered at a fixed site by a metered pump into a vehicle's running tank or a container under 250 litres capacity. This means deliveries to jerry cans at a depot, or deliveries by hose from a bulk tank to a vehicle at a non-fixed site, may not be retail sales even if under 3 000 litres, and thus may require a wholesale licence. Conversely, a sale of 10 000 litres delivered by metered pump into a vehicle's tank may be a retail sale if the quantity is below any prescribed alternative threshold? Actually, section 4A(1) says retail quantity means a quantity not exceeding 3 000 litres or other prescribed quantity, AND the delivery conditions in subsection (2) must be met. If the quantity exceeds 3 000 litres, it is not a retail quantity regardless of delivery method. But for quantities below 3 000 litres, the delivery conditions are additional requirements.

Notional sale provisions could catch unexpected transactions. Section 4D allows regulations to declare that a sale and purchase occurs in specified delivery or allocation circumstances. This means that transactions that are not sales in the ordinary sense may be deemed sales for the purpose of triggering licensing requirements or other provisions. Practitioners must check any regulations made under this section.

The Minister's exemption power under section 6 is broad and can be revoked. The Minister may exempt classes of persons or petroleum products from the Act or specified provisions, unconditionally or subject to conditions. Exemptions can be varied or revoked at any time by notice. This creates uncertainty for businesses relying on an exemption, as it can be withdrawn without cause.

Self-incrimination is not a defence but offers limited use immunity. Section 46(1) removes the right to refuse to answer questions or produce records on self-incrimination grounds. However, under section 46(2), the answer or the fact of production is not admissible in evidence against the person in proceedings for an offence or penalty other than proceedings under this Act. This means an answer given under compulsion could still be used in civil proceedings or in proceedings under the Act itself (including for licence suspension or cancellation). The immunity does not extend to the contents of a record produced; only the fact of production is protected. So if a person is compelled to produce a record, the contents can be used in proceedings under the Act.

The defence under section 57 is not available for all offences. The text says it is a defence to a charge of an offence against this Act if the defendant proves the offence was not intentional and did not result from failure to take reasonable care. However, if the offence provision itself excludes this defence by wording (for example, if it says strict liability or no defence), the section 57 defence may not apply. On the face of the Act, no section expressly excludes it, but the defence is available only where it is not inconsistent. Practitioners should check each offence provision.

The limit on proceedings against the Minister under section 37 is absolute except for Part 9 reviews. No proceedings can be instituted to compel or restrain the Minister from taking any action under Part 5 (restriction and rationing). This means that even if the Minister imposes unreasonable conditions or directions, the only recourse is the review under section 47 for decisions that are reviewable (such as licence conditions fixed under section 34? Actually, section 34(1) allows the Minister to fix conditions of licences and issue directions. Are those decisions reviewable under section 47? Section 47(1) lists decisions regarding licence issue, renewal, variation, suspension, cancellation, and permit issue and cancellation. Fixing conditions by Gazette notice during a period of restriction may not be a reviewable decision. This could leave affected persons without a remedy except perhaps judicial review on jurisdictional grounds, which section 37 might purport to exclude.

Consent to prosecute is required and may be withheld. Section 61(2) prohibits commencing a prosecution without the Minister's consent. This means even if a clear breach occurs, a private prosecution is not possible. The Minister can effectively decide whether to enforce the Act. However, the Minister's consent can be given up to five years after the offence, providing a long window for prosecutorial decisions.

Record-keeping obligations extend beyond licensees. Section 53(1) applies to any person who carries on a business involving or related to petroleum products. This includes agents, brokers, and perhaps even large end users, if the business is related to petroleum products. The Minister may specify what records must be kept from time to time by Gazette notice, so the obligation can change without amending the Act.

The register of licensees is public. Section 50 requires the Minister to keep a register of licensees available for public inspection. This means competitors and the public can see who holds licences and perhaps infer business volumes. Licensees cannot keep their authorisation status confidential.

Permits are not transferable and must be returned on cancellation. Section 36(8) prohibits transfer of permits. Section 36(7) requires return of the permit on cancellation. Failure to return carries a penalty. This means a business cannot sell or assign a permit.

A person wishing to sell petroleum products in South Australia must first determine the nature of the sales. If the person will make retail sales (sales in a retail quantity as defined in section 4A), a retail licence must be obtained. If only wholesale sales (sales of quantities exceeding 3 000 litres or that do not meet the delivery conditions in section 4A(2)), a wholesale licence is needed. Applications must be made to the Minister in a form and manner approved by the Minister, containing required information (section 13). The application fee under the regulations must be paid before the application can be granted. Licences are valid for two years and must be renewed to continue selling. The licence conditions fixed by the Minister must be carefully reviewed and complied with, as section 17 makes breach an offence. Conditions may include premises limits, sales limits, and record-keeping requirements.

For ongoing compliance, licensees must maintain proper records. Section 53 requires any person carrying on a petroleum-related business to keep accounts, invoices, receipts, records, books and documents as required by the Minister by Gazette notice for five years after the last entry. This means licensees must monitor the Gazette for any changes to record-keeping requirements. If transporting petroleum products in quantities exceeding 3 000 litres by road in South Australia, the carrier must carry a record containing prescribed particulars at all times while transporting (section 52). The prescribed particulars would be set out in regulations. Licensees should also note that the Minister or Commissioner may at any time require the provision of information in writing under section 51, and that information may need to be verified by statutory declaration under section 55.

During periods of restriction or rationing, additional compliance burdens arise. If the Governor proclaims a period of restriction, licensees must comply with any licence conditions or directions fixed or issued by the Minister under section 34. These could include maximum price orders or sales prohibitions. Directions may be issued personally, by class, or to the public generally via Gazette, newspaper, or website. It is essential to monitor these publication channels during any declared period. If the period of restriction is also declared a rationing period, no person may sell rationed petroleum products except to a permit holder. Licensees in the ordinary course of selling petroleum products are exempt from this restriction (section 35(3)), but they must still ensure they only sell to permit holders during rationing and should verify permits. Non-exempt sellers (which is most other persons) must not sell or purchase rationed petroleum products without a permit.

Compliance with authorised officer powers is critical. Under section 44, an authorised officer may enter premises, inspect records, require answers, and require assistance. Refusal to comply with a requirement or direction is an offence under section 45 with a $5 000 penalty. Although section 46 removes the self-incrimination excuse, the limited use immunity means the answer or fact of production cannot be used in proceedings for an offence or penalty other than under the Act. It is prudent to comply and then seek legal advice about the implications. Obstruction, abusive language, or false representations are also offences.

If a person is dissatisfied with a licensing decision, section 47 provides a right to seek review by SACAT within one month of receiving notice of the decision, or within one month of receiving written reasons if reasons were requested within one month of the decision. The decision is suspended pending review, so a licensee can continue operating during the review process if their licence is suspended or cancelled. For permit decisions, similar review rights exist, but section 37 prevents other proceedings against the Minister under Part 5.

Finally, all persons involved must ensure they do not provide false or misleading information under section 54, and must not falsely claim to hold a licence or permit under section 53A. The confidentiality obligations under section 56 apply to persons engaged in the administration of the Act, but also to third parties who receive information from such persons; they must not disclose it unless permitted. Any person who becomes aware of information obtained under the Act should treat it as confidential and seek guidance before disclosure.
