Petroleum and Minerals Authority Act 1973

The Act defines several core concepts that delineate the scope of the Authority’s operations. “Petroleum” means any naturally occurring hydrocarbon or mixture of hydrocarbons in gaseous, liquid or solid state, including mixtures with hydrogen sulphide, nitrogen, helium and carbon dioxide (s 3). “Petroliferous mineral” means any naturally occurring mineral from which any hydrocarbon may be produced. “Mineral” is defined negatively as a naturally occurring substance or mixture of substances other than petroleum (s 3). “Construction material” is a subset - sand, clay, stone, earth or gravel. “Petrochemical” means a substance manufactured from petroleum products, petroleum or a petroliferous mineral, but not being a petroleum product. “Refined substance” means a metal or other substance produced by refining a metal or other substance obtained from treating minerals. “Australian continental land mass” is defined by reference to the morphological unit of which Australia forms part, extending to the outer boundary of the continental shelf under the Geneva Convention on the Continental Shelf (1958), but expressly excludes Papua New Guinea and parts adjacent to it declared by Proclamation (s 3). This definition sets the spatial limit of the Authority’s onshore and offshore activities. The Authority has the power to declare a “petroleum exploration area” or a “minerals exploration area” by notice in the Gazette (s 43(1)). Before exploring or recovering in such an area, the Authority must notify its intention in the Gazette (s 43(2)) and must have either the occupier’s written consent or a warrant from a Justice of the Peace (s 43(3)). Submarine areas below waters referred to in section 14 of the Seas and Submerged Lands Act 1973 are exempt from the consent/warrant requirement (s 43(4)). The concept of “property in petroleum and minerals” is also central. On recovery, petroleum and minerals become the property of the Authority, but the Authority is liable to pay fair and reasonable compensation to the former owner (including a State), determined by agreement or by action in the Australian Industrial Court (s 45). Compensation may take the form of a royalty, and the court must have regard to the work done by the Authority in exploring and extracting (s 45(3)). The Act also creates a warrant system under section 50 for entry onto land, either for inspection and survey (s 13) or for occupation and construction (s 14). The grounds for a warrant include that the land is within a declared exploration area, the Authority has resolved to commence operations, and the occupier has refused consent or it is impracticable to obtain consent within a reasonable time. The Act imposes a duty on the Authority to cause as little detriment and inconvenience as possible (s 47) and provides for compensation for injurious affection, including temporary and permanent damage and taking of materials. These concepts together create a regulatory and operational framework for a government corporation to engage in all stages of the resources value chain, subject to constitutional limits and procedural safeguards.

The Act directly affects the Petroleum and Minerals Authority itself as a body corporate (s 16). It also affects the five members of the Authority: the Chairman, the Secretary to the Department of Minerals and Energy, the Executive Member, and two part-time members (s 17(1)). The Chairman and Executive Member are full-time; the other two (other than the Secretary) are part-time (s 17(2)). All but the Secretary are appointed by the Governor-General for up to seven years and are eligible for reappointment (s 17(3)). The Minister for Minerals and Energy is given powers to direct the Authority (s 15), approve acquisitions and disposals above $500,000 (s 37), grant leave of absence (s 19), and receive reports (ss 42, 53). The Treasurer is involved in approving banks, determining maximum underwriting and guarantee limits (s 12(3)-(4)), making capital available (s 32), approving borrowing (s 33), guaranteeing loans (s 33(4)), and concurring with profit determinations (s 36). The Secretary to the Department of Minerals and Energy is both a member and, in certain circumstances, can convene meetings and preside (s 23). The Auditor-General inspects and audits the Authority’s accounts and reports to the Minister (s 40). Staff of the Authority are appointed by the Authority (s 25) and are not covered by the Public Service Arbitration Act (s 26). The Chairman and Executive Member are deemed employees for superannuation purposes (s 29). Persons and bodies with whom the Authority may contract, partner, or lend money are affected: section 12(1) permits agreements for work or services, formation of companies, underwriting, lending to mining undertakings, and partnerships for risk-sharing. Section 12(2) restricts the Authority from exploring for or recovering petroleum or minerals for another person on the Australian continental land mass unless that person is authorised to do so. Occupiers of land are affected by the Authority’s powers of entry (s 13) and occupation (s 14), subject to consent or warrant, and are entitled to compensation (s 47). Owners of petroleum or minerals in place (including State governments) have their proprietary rights extinguished upon recovery by the Authority, but receive compensation (s 45). The Act also applies to foreigners (s 4) and to all persons who may obstruct the Authority (penalties under ss 13(3), 14(4), 51). Courts are affected: State and Territory courts are invested with federal jurisdiction for offences (s 52), and the Australian Industrial Court has jurisdiction for compensation claims (s 45(2)). Justices of the Peace are empowered to issue warrants (s 50). Finally, the Act affects anyone wishing to carry out work that may adversely affect Authority works - such work is prohibited (s 51). The Act’s invalidity means that none of these persons were ever actually affected in law, but the intended scheme is clear.

The Act imposes a set of substantive duties on the Authority. Section 10(1) requires the Authority to make thorough preliminary investigations in accordance with generally accepted principles before exploring for or recovering petroleum or minerals. Section 10(2) directs the Authority to perform its functions so as to ensure, as far as reasonably practicable, that adequate quantities of petroleum or minerals ordinarily imported into Australia are available for use in Australia at any time when export to Australia is restricted or prohibited by another country. Section 10(3) imposes operational duties: to carry on operations in a proper and workmanlike manner and in accordance with good oil field practice in petroleum exploration areas; to ensure structures and equipment are maintained and removed when not needed; to secure safety, health and welfare of persons engaged in operations in exploration areas; to carry on submarine-area operations in a manner that does not interfere with navigation, fishing, conservation of sea and seabed resources, or other lawful operations, to a greater extent than necessary; and to consider factors connected with ecology and the environment. Section 10(4) adds specific petroleum-related duties: control flow and prevent waste or escape of petroleum or water; prevent escape of mixtures; prevent damage to petroleum-bearing strata; keep separate each petroleum pool discovered; and prevent water or other matter entering a petroleum pool except in accordance with good oil field practice. Section 47(1) requires the Authority to cause as little detriment and inconvenience and do as little damage as possible in exercising its powers. The Authority also has a duty to comply with ministerial directions (s 15(1)), which must be included in its annual report (s 15(3)). On the rights side, the Authority has the right to enter land (with consent or warrant) for inspection, survey, and occupation for construction and related acts (ss 13, 14). Upon lawful recovery, the Authority acquires property in the petroleum or minerals (s 45(1)). The Authority has the right to delegate its powers to members or staff (s 24). The Authority may borrow, invest, and give guarantees (ss 33, 35). Landowners and occupiers have a right to compensation for injurious affection, damage, and taking of materials under section 47, and former owners of petroleum and minerals have a right to fair and reasonable compensation under section 45, enforceable by action in the Australian Industrial Court. Occupiers have the right to demand production of a warrant before occupation (s 14(5)). Part-time members have a duty to disclose interests in contracts at Authority meetings (s 21(3)) and must not participate in deliberations on those contracts (s 21(4)). The Authority must keep proper accounts (s 38) and submit financial statements to the Auditor-General (s 53(2)). The right to compensation is not exclusive: section 47(5) preserves other liabilities the Authority may have. The Auditor-General has a right of access to all accounts (s 40(4)). The Minister has the right to require information (s 42). These duties and rights create a framework aimed at balancing the Authority’s commercial flexibility with public accountability and protection of private interests.

The Act creates several specific offences, each with prescribed penalties. Under section 13(3), a person who without reasonable excuse obstructs or hinders an authorised person acting in pursuance of the power to enter land for inspection and survey is liable to a penalty of $200. Similarly, section 14(4) penalises obstruction or hindrance of the Authority’s exercise of powers to occupy land and do specified acts (construct, take materials, make cuttings, erect buildings, etc.) with a penalty of $200. A more serious offence appears in section 51(1): a person must not carry out any work that adversely affects or interferes with any works or proposed works of the Authority, or their use or proposed use. This offence is punishable summarily by a fine not exceeding $200 or imprisonment not exceeding 6 months, or both; or upon conviction on indictment by a fine not exceeding $2,000 or imprisonment not exceeding 2 years, or both (s 51(3)). Section 51(2) provides double-jeopardy protection - an offender is not liable to be punished more than once in respect of the same offence. Proceedings may be brought in a court of summary jurisdiction, which may commit the defendant for trial or, with the defendant’s consent, determine the proceedings summarily (s 51(4)). Section 40(7) creates an offence of failing to comply with a requirement of the Auditor-General or an authorised officer to furnish information, punishable by a fine not exceeding $200. Enforcement mechanisms include the warrant system under section 50: a Justice of the Peace may grant a warrant if satisfied of the grounds (land in an exploration area, notification in Gazette, Authority resolution to commence, and refusal or impracticability of consent). The warrant authorises entry for exploration or recovery, or for occupation and construction. The Act also provides for compensation as an enforcement remedy: the owner of land injuriously affected may seek compensation (s 47), and the owner of petroleum or minerals may sue in the Australian Industrial Court (s 45). Section 52 vests the several courts of the States with federal jurisdiction and confers jurisdiction on Territory courts for offences committed outside Australia and the Territory of Ashmore and Cartier Islands. The trial on indictment of an offence not committed within a State may be held in any State or Territory (s 52(3)). State and Territory laws for arrest, custody, summary conviction, commitment for trial, trial on indictment, and appeals apply to offences committed outside Australia and the Territories, as far as they are applicable (s 52(4)). The Judiciary Act 1903-1969 applies except as provided (s 52(5)). The regulations may prescribe penalties not exceeding a fine of $200 or imprisonment for 6 months, or both (s 54(1)(c)). The regulations may also make provision for safety and operations (s 54(2)). Section 51(5) preserves civil remedies. Overall, the enforcement framework is a mix of criminal penalties for obstruction and interference, warrant-based enforcement for entry, and compensatory remedies for property rights.

Section 46 provides a general immunity: subject to the Act, the Authority is not subject to any requirement, obligation, liability, penalty or disability under a law of Australia, or of a State or Territory, to which Australia is not subject. This means the Authority is placed on the same footing as the Commonwealth itself for the purposes of most laws. Section 41(1) makes the Authority subject to taxation under the laws of Australia (i.e., Commonwealth tax). However, the Authority is not subject to taxation under a law of a State or Territory unless the regulations otherwise provide (s 41(2)-(3)). Furthermore, the Authority is expressly declared not to be a public authority for the purpose of paragraph 23(d) of the Income Tax Assessment Act 1936-1973 (s 41(4)), which would have affected its tax-exempt status. For land acquisition, the Lands Acquisition Act 1955-1966 applies, deeming acquisition for the Authority as acquisition for a public purpose (s 48(1)). The Act also adapts the concept of easements to allow easements in favour of the Authority without a dominant tenement for pipeline purposes (s 48(2)-(3)). The Seas and Submerged Lands Act 1973 is referenced: section 43(4) exempts submarine areas below waters covered by section 14 of that Act from the consent/warrant requirement for exploration. Industrial relations laws are specifically dealt with. The Public Service Arbitration Act 1920-1972 does not apply to Authority employees (s 26). However, other industrial awards under other Acts are preserved (s 27). The Superannuation Act 1922-1973 applies: the Authority is an approved authority, and the Chairman and Executive Member are deemed to give their whole time and to be employed by the Authority (s 29). The Officers’ Rights Declaration Act 1928-1969 applies to former Australian Public Service officers or employees who join the Authority, preserving their existing and accruing rights (s 30). Section 51(6) is a savings provision: nothing in section 51 prevents or affects the operation of a State law prohibiting acts also prohibited by this Act. The regulations may apply provisions of other laws (of Australia, a State or Territory) to the Authority, with or without modifications (s 54(3)). Section 52 provides for the interaction with the Judiciary Act 1903-1969 and invests State courts with federal jurisdiction. The Act also interacts with the common law of compensation: section 47(5) preserves any liability of the Authority apart from that section, meaning that compensation claims not covered by the statutory scheme may still be pursued. Overall, the Act attempts to create a bespoke legal regime for the Authority, overriding many general laws but leaving room for application of specified Commonwealth legislation and preserving some State regulatory powers.

The Act as presented is the original enactment: Petroleum and Minerals Authority Act 1973, Act No. 43 of 1974. It received Royal Assent and was numbered accordingly. The short title is stated as 1973, but the Act number indicates it was enacted in 1974. Section 2 provides that the Act shall come into operation on a date to be fixed by Proclamation. However, the note appended to the Act records that the High Court held the Act not to be a valid law of the Commonwealth (Victoria v Commonwealth (1975) 49 ALJR 243). As a result, no Proclamation was ever made (or if made, it would have been invalid). The Act never came into force. There are no amendments shown in the provided text. The Act does not contain any provision for its own amendment or for the making of regulations that would amend it (regulations are subordinate and must not be inconsistent with the Act). The note about invalidity is part of the official text. The Act’s legislative history is therefore minimal: it was passed, challenged, and struck down. No later amending acts are noted in the source. The text appears to be the original version as enacted. Because the Act was held invalid, any subsequent legislative activity (such as repeal or replacement) would have occurred separately, but the source does not disclose that. The provided text includes a reference to “1 January 1975” in sections 18(1) and 18(2) for temporary rates of remuneration until that date, indicating an assumption of operation before that date. The Act also refers to the Superannuation Act 1922-1973 and the Income Tax Assessment Act 1936-1973, showing the state of cross-references at the time of enactment. The definition of “Convention” refers to the Geneva Convention on the Continental Shelf 1958. The phrase “Australian continental land mass” includes a definition that allows for boundaries determined by agreement with another country “whether before or after the commencement of this Act” (s 3), indicating forward-looking drafting. No subsequent amending history can be inferred from the text. The Act remains on the statute books as a dead letter. Its amendment history, if any, would be a matter of external research beyond this source.

The sole litigation event recorded in the Act itself is the High Court decision noted at the end: State of Victoria and Another v Commonwealth of Australia and Another; State of New South Wales and Another v Commonwealth of Australia and Another; State of Western Australia v Commonwealth of Australia; and State of Queensland and Another v Commonwealth of Australia and Another (1975) 49 ALJR 243. This was a challenge by four States to the validity of the Act. The High Court held that the Petroleum and Minerals Authority Act 1973 was not a valid law of the Commonwealth. The precise grounds of invalidity are not set out in the Act’s note, but the case is a significant example of the High Court’s jurisprudence on Commonwealth legislative power under sections 51 and 122 of the Constitution, particularly in relation to the corporations power, the trade and commerce power, the territories power, and the defence power. The Court’s decision effectively prevented the Authority from ever being established. No other litigation is referenced in the Act. There is no mention of any compensation claims brought under section 45, or prosecutions under section 51, since the Act never came into force. The note is terse and simply states the outcome. The litigation thus has no practical application beyond the constitutional ruling. The Act itself provides for jurisdiction of courts (s 52) and for compensation actions in the Australian Industrial Court (s 45), but those provisions were never enlivened. The invalidity meant that the warrant provisions (s 50) and the offence provisions could not be invoked. The litigation history for this Act is therefore limited to this single declaratory case. Any subsequent litigation might have involved challenges to actions taken under the Act for the brief period after its passage and before the High Court decision, but the source does not record any. The case is often cited in constitutional law for the limits on the Commonwealth’s power to create statutory corporations that engage in commercial activities beyond the Commonwealth’s enumerated heads of power. The note is an integral part of the Act’s text, indicating that the Commonwealth itself acknowledges the invalidity.

Several provisions in the Act contain traps for the unwary. The most significant gotcha is the Act’s invalidity: despite its comprehensive scheme, the Act never became law, and reliance on its provisions would be misplaced. However, assuming a hypothetical valid operation, the following points are noteworthy. Section 9(1) severely limits the Authority’s functions to five specific heads: a Territory, submarine areas of the continental land mass, trade and commerce (international, inter-State, inter-Territory, or Territory-State), defence reserves, and incidental matters. This means the Authority could not operate solely within a State on non-submarine land unless it could bring itself within the trade and commerce or defence limbs. Section 9(2) reinforces that sections 6-8 only confer functions that may be performed under s 9(1). A reader might overlook these restrictions and assume the Authority has unrestricted capacity. Section 10(2) imposes a duty to ensure adequate supplies of ordinarily imported petroleum or minerals when export to Australia is restricted by another country. This is a potentially open-ended obligation, and failure could expose the Authority to criticism but likely no legal liability. Sections 13 and 14 require either consent or a warrant for entry; the warrant application must satisfy several specific conditions (s 50(a)-(c)). If any condition is not met, entry could be unlawful and trespass actions could lie. The warrant is issued by a Justice of the Peace, not a magistrate or judge, which may raise procedural fairness concerns. Section 14(5) requires the Authority to produce the warrant upon demand - failure to do so could be a procedural irregularity. Section 45 vests property in the Authority upon recovery, but compensation is to be determined by agreement or by action in the Australian Industrial Court. The court may award a royalty, and must consider the Authority’s work in exploring and extracting. This could result in compensation below market value if the Authority’s work is extensive. Section 46 provides that the Authority is not subject to any law to which Australia is not subject. This broadly immunises the Authority from many State and Commonwealth laws, but it is still subject to the Act itself, s 41(1) (Commonwealth tax), and any regulations made under s 54. Section 12(2) prohibits the Authority from exploring for or recovering petroleum or minerals for another person on the Australian continental land mass unless that person is authorised to do so. This limits the Authority’s ability to act as a contractor without ensuring the counterparty holds the necessary title or licence. Section 37 requires ministerial approval for acquisitions, disposals, and construction contracts exceeding $500,000 (or a higher prescribed amount) and for leases exceeding 10 years. Failure to obtain approval would likely render the transaction void or unlawful. Section 15(3) requires that ministerial directions be set out in the annual report, creating transparency but also potential for political influence to be exposed. Section 23(5) is a transitional provision: until part-time members are appointed or 6 months after commencement, a meeting with only the Secretary and Executive Member is valid, and the Secretary acts as Chairman. This could lead to decisions being made by only two people. Part-time members must disclose interests (s 21(3)) and cannot participate in related decisions (s 21(4)). Non-compliance triggers automatic termination by the Governor-General (s 21(2)(c)). The regulations under s 54(3) can apply other laws to the Authority with modifications, so the Authority’s obligations could be expanded by delegated legislation without parliamentary amendment. Finally, s 51 prohibits interference with works or proposed works - a broad concept that could catch many third-party activities, and the offence is triable either way, with potential imprisonment of up to 2 years.

Since the Act was held invalid, formal compliance was never required. However, for a hypothetical compliance analysis, an Authority established under this Act would need to observe the following. The first step is to ensure that all operations fall within the five heads of s 9(1): territorial, submarine, trade/commerce, defence, or incidental. An internal legal review should confirm constitutional authority before commencing any project. The Authority must comply with ministerial directions under s 15(1) and include any such direction in its annual report (s 15(3)). Before exploring or recovering in any declared exploration area, the Authority must publish a Gazette notice of intention (s 43(2)) and obtain either the occupier’s written consent or a warrant (s 43(3)). For submarine areas below waters referred to in s 14 of the Seas and Submerged Lands Act 1973, no consent or warrant is needed (s 43(4)). The Authority must make thorough preliminary investigations in accordance with generally accepted principles (s 10(1)) and carry on operations in a proper and workmanlike manner, with good oil field practice for petroleum (s 10(3)-(4)). Environmental and ecological factors must be considered (s 10(3)(f)). The Authority must cause as little detriment as possible (s 47(1)). Compensation must be paid for injurious affection, damage, and taking of materials (s 47(2)-(4)). For recovered petroleum and minerals, compensation must be paid to the former owner, either by agreement or through an action in the Australian Industrial Court (s 45). The Authority must keep proper accounts in accordance with commercial accounting principles (s 38) and maintain at least one bank account with an approved bank (s 34). All moneys must be paid into that account (s 34(2)). The Authority must obtain Treasury approval for borrowing (s 33) and ministerial approval for acquisitions, disposals, and construction contracts above $500,000 or the prescribed amount (s 37). The Authority must pursue a financial policy directed towards securing revenues sufficient to meet expenditure and provide a reasonable return on capital (s 31). Capital repayments to Australia are subject to ministerial determination with Treasurer concurrence (s 32(4)). The Authority must submit financial statements to the Auditor-General for audit and report (s 53). The annual report must be furnished to the Minister as soon as practicable after 30 June each year (s 53(1)). The Authority must comply with Commonwealth taxation laws (s 41(1)). If directed to carry on operations outside Australia for overseas aid purposes, the Authority must keep a separate account and may claim reimbursement for losses (s 39). The Authority may delegate its powers to members or staff by instrument under seal (s 24). Part-time members must disclose interests in contracts (s 21(3)) and must not participate in related decisions (s 21(4)). The Authority must mark the route of any pipeline constructed (s 49). In case of third-party interference, the Authority may pursue criminal prosecution under s 51 or civil remedies (s 51(5)). The regulations may impose additional compliance obligations, and the Authority must ensure it does not contravene them. Overall, the compliance framework requires careful attention to constitutional limits, procedural prerequisites for entry and operations, financial accountability, and compensation obligations.
