The Act rests on a handful of legal and administrative concepts. Approved Agreement: the Agreement in the Schedule is the operative contract between Commonwealth, New South Wales and South Australia; once the Act is in force it has statutory backing in New South Wales (s 4(1); Schedule cl 2(1)-(3)). Authorisation and construction: the State of South Australia is expressly authorised to construct and maintain the Railway within New South Wales and to exercise constructing authority powers notwithstanding conflicting provisions in the Public Works Act 1912 (s 6(1); s 5(1) treats the NSW Commissioner for Railways as having powers of a constructing authority under the PWA for the purpose of resumption and acquisition). Land acquisition and vesting: the Governor may resume, appropriate or acquire land under the Public Works Act 1912 powers (s 5(1)); such land is to be vested in the South Australian Railways Commissioner (s 5(2)), subject to an express exception for land acquired for public roads or services unconnected with the Railway (s 5(2)).

Cross-jurisdictional control and application of South Australian law: the Act gives South Australia the right to operate, control and manage the Railway (s 7). Section 8 elaborates that the South Australian Railways Commissioner (the Commissioner) may operate the Railway in accordance with the Agreement and with laws applicable to railways vested in the Commissioner under the South Australian Railways Commissioner’s Act 1936, subject to section 84 of that Act being excluded. Section 8(3) authorises the Commissioner to demand and collect charges, fares, tolls, freights and rates like those levied under by‑laws or regulations applicable to other South Australian railways, and to exercise similar powers, privileges and liabilities as the Commissioner does elsewhere. Section 8(5) expressly extends sections 115-123 of the South Australian Railways Commissioner’s Act 1936, and by‑laws and regulations under that Act, to the Railway, and provides summary recovery in the Local Court and mechanisms for evidentiary proof of appointments and of by‑laws (s 8(5)(a)-(d)).

Employment and industrial conditions: s 8(6) imports the same terms and conditions of employment, including workers’ compensation entitlement and the same salary or wage rates, for officers and employees employed by the Commissioner in connection with the Railway as apply to officers and employees of the Commissioner in South Australia. This operates notwithstanding other Acts, awards or industrial agreements.

Financial architecture and limits: Schedule Part 3 (cls 11-16) sets out the financial scheme. The Commonwealth funds the project subject to ceilings and categories of capped payments (cl 13). The Commonwealth contemplates providing funds to meet expenditure under the Agreement (cl 11), but payments to States require Ministerial approval, certification from the relevant Commissioner and the State Auditor (cl 14(2)-(4)), and the Commonwealth’s total liability is limited by specified sums for certain works (cl 13). Repayment by South Australia is defined: three-tenths of Commonwealth payments are to be repaid by SA from Consolidated Revenue over fifty years with interest (Schedule cl 16(1)-(3)). Administrative oversight: plans, master plans, specifications and estimates are required, with States obliged to provide these to the Minister (Schedule cl 5), to permit inspection by persons authorised by the Minister (cl 9), and to provide quarterly progress and financial reporting (cl 18). Audit functions are routed through State Auditor-Generals with sharing to the Commonwealth Auditor-General (cl 19).

Standards and technical specifications: the Schedule contains technical standards for earthworks, grading, rails, sleep ers, ballast, signalling and communications (Schedule Part B). The route is specified (Schedule Part A). Variation of the Schedule is allowed where the Minister approves with the concurrence or request of the State(s) concerned (Schedule cl 3(3)).

Limit on judicial relief and validation: s 4(3) prevents Courts granting injunctions that would operate to prevent or restrict works under the Act or Agreement; claims must be for damages or compensation only. Section 4(2) validates any acts or work done before commencement of the Act in connection with the Railway.

These concepts create a legal framework that converts an inter-governmental arrangement into a statutory allocation of powers, funding constraints, operational control and administrative oversight, while restricting interlocutory judicial relief and applying South Australian regulatory frameworks to railway operations located in New South Wales.

The Act creates a specific, concentrated set of legal relationships and identifies the persons and institutions directly affected.

Governments and ministers

• Commonwealth: supplies the agreed funds under Schedule Part 3 (cls 11-16) and exercises approval and oversight through the Minister of State for Shipping and Transport, who is given approvals and inspection rights (Schedule cls 11, 22, 9). The Commonwealth’s Parliament must approve the Agreement to give it force (Schedule cl 2(1)).
• State of New South Wales: obliged to authorise South Australia to own, construct and operate the Railway and to resume/appropriate/acquire land required for the work and make it available to South Australia subject to reimbursement (s 5(1)-(2); Schedule cl 7(b)). The NSW Commissioner for Railways is given powers of a constructing authority under the Public Works Act 1912 for resumption and acquisition (s 5(1)).
• State of South Australia: authorised to own, construct, operate and maintain the Railway (s 6(1); s 7). South Australia (through the Commissioner) will operate the Railway and collect charges (s 8(2)-(3)); it also has an obligation to repay 30 per cent of Commonwealth payments over time from Consolidated Revenue (Schedule cl 16(1)).

Railway authorities and officers

• South Australian Railways Commissioner: becomes the primary operational decision-maker and legal owner for vested land (s 5(2); s 8(2)-(5)). The Commissioner is empowered to collect fares and charges, apply South Australian by‑laws and regulations, appoint persons to enforce penalties and must observe limitations on disposal of vested land without Governor approval (s 8(3)-(5), (4)). Employment terms for officers and employees in connection with the Railway are to match those applying in South Australia (s 8(6)).
• New South Wales Commissioner for Railways: is the constructing authority under the Public Works Act for resumption/acquisition, as contemplated in s 5(1), and must certify works for payment claims where appropriate (Schedule cl 14(4)(a)).

Private landowners and local communities

• Owners of land in New South Wales on the route: subject to resumption, appropriation or acquisition under Public Works Act 1912 procedures, with the Governor empowered to effect that (s 5(1)). Land so acquired is to be vested in the South Australian Railways Commissioner (s 5(2)), except where acquired for a public road or public service unconnected with the Railway (s 5(2)). The Act also validates any acts already performed before commencement (s 4(2)). Importantly, claimants with rights potentially affected by acquisition or construction are limited to damages or compensation and cannot obtain injunctions that would prevent works authorised by the Act or Agreement (s 4(3)).
• Owners of private sidings and privately owned rail tank cars between Port Pirie and Broken Hill who seek conversion to standard gauge: they are affected because conversion is subject to Ministerial approval and partly funded only up to half the cost per siding or car as the Minister approves (Schedule cl 3(1)(d),(e); cl 13(b),(c)). The Minister’s approval is discretionary.

Contractors, suppliers and tenderers

• Entities tendering for construction and associated works: the States are directed to invite public tenders except where undesirable to do so to the Minister’s satisfaction (Schedule cl 8). A State may itself tender. Contract awards and performance will feed into expenditure claims for Commonwealth payments, which require certification and audit (Schedule cls 14-15, 18-19).
• Rolling stock manufacturers and owners: work on construction and conversion of rolling stock is addressed specifically (Schedule cl 3(1)(f); cl 12 allocates expenditure across this and the 1949 Agreement).

Workers and unions

• Employees of the Commissioner working on the Railway in New South Wales: their terms and conditions of employment are to mirror those applying in South Australia, including rates of salaries or wages and workers’ compensation rules (s 8(6)). The Act states that these provisions apply notwithstanding any other Act, award or industrial agreement.

Courts, auditors and regulatory bodies

• Local Courts: summary recovery of penalties extended by the South Australian Railways Commissioner’s Act 1936 applied mutatis mutandis to the Railway, meaning Local Courts may hear and determine those penalties (s 8(5)(b)).
• Auditor‑Generals: the State Auditor-General audits accounts and furnishes reports to the Commonwealth Auditor-General until work is completed to the Minister’s satisfaction; the Commonwealth Auditor-General may request additional information and inspection rights are given (Schedule cl 19).

Users and shippers

• Passengers and freight customers: subject to rates, tolls, freights and fares that the Commissioner may demand and enforce (s 8(3)(a)). The Agreement anticipates that the Railway will provide service to customers and includes provisions for conversion and construction of rolling stock and facilities necessary to provide service (Schedule cl 3(1)(c),(f),(g)).

Taxpayers and public finances

• Commonwealth taxpayers: bear the immediate funding burden up to the caps and subject to Ministerial approval (Schedule cl 11, cl 13).
• South Australian taxpayers: carry a long‑term repayment obligation equal to three-tenths of Commonwealth payments, payable from Consolidated Revenue over fifty annual instalments with interest tied to the Commonwealth’s long-term loan rate at the relevant time (Schedule cl 16(1)-(3)).

The Act therefore creates concentrated benefits,operational control, fare revenue and asset ownership,for South Australia, while distributing financing and oversight across the Commonwealth and the States, and constraining remedies available to private parties affected by construction in New South Wales.

The Act and its Schedule allocate specific duties and rights among the Commonwealth, the States, the South Australian Railways Commissioner and private actors. Below are the principal ones, with section cross‑references.

Duties imposed on States and officials

• Duty to legislate and implement: each party agreed to take practicable steps to seek enactment of legislation to approve and implement the Agreement (Schedule cl 2(2)-(3)). In New South Wales, the Act is that legislative approval.
• Duty to carry out work with due diligence and efficiency: each State must carry out parts of the work for which it is responsible with due diligence and efficiency and in accordance with the Agreement, master plan and specifications (Schedule cl 6(1)).
• Duty to plan and provide documentation: each State must prepare master plans, plans, specifications and cost estimates for parts of the work it is responsible for, and make them available to the Minister and other States where appropriate (Schedule cl 5).
• Duty to invite public tenders: states are to invite public tenders except where the Minister is satisfied that inviting tenders is undesirable, but a State may act as tenderer in appropriate circumstances (Schedule cl 8).
• Duty to supply information and promptly notify interference: each State must furnish information reasonably requested by the Minister and promptly inform the Minister of matters that interfere, or are likely to interfere, with the accomplishment of obligations under the Agreement (Schedule cl 20).
• Duty to keep accounts, provide progress reports: full accounts, records, quarterly progress and financial statements must be furnished to the Minister (Schedule cl 18). Statements of expenditure must be certified by the relevant Commissioner and the State Auditor-General before payment by the Commonwealth (Schedule cl 14(4)).
• Duty to permit audits and inspections: State accounts and records are to be audited by the State Auditor-General and reports given to the Commonwealth Auditor-General at least once a year until the work is completed to the Minister’s satisfaction (Schedule cl 19). The Minister can authorise persons to inspect the work and related documents (Schedule cl 9).

Rights and powers conferred on South Australia and the Commissioner

• Right to own, construct, operate and maintain the Railway: expressly conferred (s 6(1); Schedule cl 7(a)).
• Right to operate, control and manage the Railway and to apply SA laws insofar as consistent with the Agreement: s 8(2)-(3) permits operation in accordance with the Agreement and laws applicable to other SA railways. The Commissioner may demand, collect and enforce rates, tolls, freights, charges and fares (s 8(3)(a)).
• Power to exercise like powers and be subject to like duties and liabilities as the Commissioner has for other SA railways under the South Australian Railways Commissioner’s Act 1936 (s 8(3)(b)). Sections 115-123 of the SA Act and by‑laws and regulations are extended, mutatis mutandis, to the Railway (s 8(5)(a)).
• Power to recover penalties summarily and to appoint persons to recover penalties; appointment letters and copies of SA by‑laws printed by the SA Government Printer are proof of appointment and of regulatory content in penalty proceedings (s 8(5)(b)-(d)).
• Discretion to fence or not: notwithstanding the Public Works Act 1912, the SA Commissioner is not compelled to make or maintain fences along the Railway (s 6(2)), but may do so in its discretion.

Financial rights and duties

• Commonwealth funding: the Commonwealth is to provide funds required to meet expenditure under the Agreement subject to the limitation that certain categories of work are capped and subject to Ministerial approval (Schedule cls 11-14). The Minister may treat some contributions as working advances (Schedule cl 14(1)).
• Conditions on payments: payments are limited to expenditure approved and directly incurred in carrying out the work; the Minister must be satisfied as to those conditions (Schedule cl 14(2)-(3)).
• Repayment duty on South Australia: SA must pay three-tenths of payments made under the Agreement in each financial year by fifty equal annual contributions from Consolidated Revenue, with interest computed from the start of the financial year in which the relevant payment was made (Schedule cl 16(1)-(2)). The Minister’s decisions on deemed allocations (cl 16(3)) may affect SA’s repayment load.

Limitations on judicial remedies

• No injunctions to restrain work: claims related directly or indirectly to construction of the Railway are limited to damages or compensation; courts must not grant injunctions that would prevent or restrict works under the Act or Agreement (s 4(3)). This is a substantive restriction on interlocutory and final equitable remedies.

Ministerial discretions and approvals

• Minister’s approval is required for several items: conversions of private sidings and privately owned rail tank cars (Schedule cl 3(1)(d),(e)), construction/ conversion of rolling stock deemed necessary (cl 3(1)(f)), funds not otherwise covered (cl 11(4)); the Minister may approve variations to the Schedule (cl 3(3)) and must confer with State Ministers on matters if requested (cl 22). The Minister’s satisfaction and approval are recurring preconditions to payments and actions.

Other specific rights and duties

• Disposal of vested land: the Commissioner shall not dispose of land vested pursuant to the Act except with the approval of the Governor (s 8(4)).
• Extension of SA employment terms: officers and employees engaged on the Railway are entitled to the same wages, conditions and workers’ compensation entitlements as in SA (s 8(6)).

These allocations create a clear map of decision-making authority and fiscal responsibility, while imposing administrative and reporting duties on States and giving operational and enforcement rights to the South Australian Railways Commissioner.

The Act embeds enforcement mechanisms that combine administrative, summary penalty and civil compensation mechanisms, and it constrains judicial intervention.

Summary penalties and recovery

• Extension of SA Railways Act enforcement regime: s 8(5)(a) extends sections 115-123 of the South Australian Railways Commissioner’s Act 1936 and the by‑laws and regulations under that Act, mutatis mutandis, to the Railway. While the Act does not reproduce those provisions, it incorporates them so that offences or contraventions under those provisions and by‑laws apply to the Railway.
• Summary recovery before Local Court: s 8(5)(b) provides that any penalty imposed in respect of the applied provisions, by‑laws and regulations may be recovered in a summary manner before the Local Court. This places penalties within the jurisdiction of summary process, limiting the forum for enforcement to Local Courts for those penalties.
• Enforcement by appointed persons: s 8(5)(c) allows any person appointed by the Commissioner to recover penalties. The production of a document purporting to be signed by the Commissioner appointing the named person is conclusive evidence of appointment in penalty proceedings (s 8(5)(c)). This procedural evidence rule simplifies proof of enforcement authority.
• Documentary evidence rules: s 8(5)(d) states that a document purporting to be a copy of the South Australian Railways Commissioner’s Act 1936, or a by‑law or regulation thereunder and to be printed by the Government Printer of South Australia, shall be sufficient evidence of contents and that it was in force at the relevant time. This evidentiary provision eases prosecution and enforcement by reducing the proof burden for the content and force of regulatory instruments.

Civil remedies and judicial limits

• Claims limited to damages or compensation: s 4(3) limits any claim made by any person in respect of any matter directly or indirectly related to construction of the Railway or to the execution or carrying into effect of the Agreement to damages or compensation only. Crucially, s 4(3) bars injunctions that would operate to prevent or restrict any person from carrying out any part of the work authorised by the Act or the Agreement. This is an express curtailment of equitable relief and interlocutory judicial control over works authorised by the statute.
• Validation of prior acts: s 4(2) validates acts performed or work carried out before commencement in connection with the Railway, which reduces the prospect of undoing prior work through enforcement actions.

Administrative oversight and audit enforcement

• Certification and audit preconditions to payment: Schedule cl 14(4) requires that statements of expenditure for payment applications be certified by the relevant Commissioner that the work was carried out in accordance with the standards, and by the State Auditor-General that the expenditure was properly made. The Commonwealth will not pay expenditures not approved or ratified by the Minister (Schedule cl 14(2)-(3)). The Minister’s capacity to refuse payment on grounds of non-compliance is an administrative enforcement lever.
• Auditor-General reporting to Commonwealth Auditor-General: Schedule cl 19 requires annual auditing and reporting by State Auditor-Generals to the Commonwealth Auditor-General, including statements on whether receipts and expenditure are in accordance with the Agreement (Schedule cl 19(2)). The Commonwealth Auditor-General may require inspection and additional information (Schedule cl 19(3)). These audit mechanisms provide oversight and an accountability route for public funds.
• Ministerial inspection rights: Schedule cl 9 allows persons authorised by the Minister to inspect the work and associated documents. Injecting a Commonwealth inspection function increases monitoring capability and creates potential compliance consequences if inspections disclose deviations.

Practical enforcement features and friction points

• By‑laws and regulations as instruments of control: because the Commissioner may apply by‑laws and regulations, and collect and enforce charges (s 8(3)-(5)), compliance at the operational level can be enforced through administrative processes and summary proceedings in the Local Court.
• Evidence and appointment shortcuts: the provisions on documentary proof (s 8(5)(c)-(d)) reduce procedural complexity in enforcement actions and could accelerate summary proceedings.
• Limits on equitable relief: the ban on injunctive relief fundamentally changes enforcement options for parties adversely affected by construction. Affected parties may still seek damages or compensation but cannot seek interlocutory or final injunctions that would stop works, subject to the Court’s interpretation of the section and any constitutional or other limits not addressed in the Act.

In sum, enforcement under the Act relies on a blend of administrative preconditions to funding, statutory incorporation of South Australian regulatory offences and summary recovery via Local Court, audit and inspection regimes, and a statutory bar against injunctive relief. These features steer disputes toward quantifiable monetary remedies and administrative oversight rather than injunctive restraint.

The Act expressly interacts with several pre-existing statutory frameworks and agreements, and it creates cross-jurisdictional legal layering.

Public Works Act 1912 (NSW)

• Resumption, appropriation and acquisition of land are to be carried out under the provisions of the Public Works Act 1912, as subsequently amended (s 5(1)). The Commissioner for Railways for the State of New South Wales is given all the powers of a constructing authority under that Act for the purposes of resumption and acquisition. The Act therefore operates within the procedural acquisition regime of the Public Works Act but subjects the constructing-authority role to the special inter-governmental allocation for this project.

South Australian Railways Commissioner’s Act 1936

• The Act imports, applies and extends provisions of the South Australian Railways Commissioner’s Act 1936 to the Railway. Section 8(2)-(6) gives the South Australian Railways Commissioner the ability to operate the Railway in accordance with that Act, and section 8(5)(a) expressly extends ss 115-123 and the by‑laws and regulations under that Act to the Railway. The Act also provides evidentiary rules for copies of that Act and its by‑laws (s 8(5)(d)). Section 8(6) imports employment terms and workers’ compensation rules applicable under the SA Act for staff working on the Railway.

Inter-governmental Agreements: 1949 Agreement

• The Schedule references a prior 1949 Agreement. The Schedule (cl 12) allocates certain rolling stock expenditure between the 1949 Agreement and this Agreement (88 per cent to 1949 Agreement; 12 per cent to this Agreement). Clause 23 of the Schedule rescinds clause 23 of the 1949 Agreement. The two agreements are therefore linked operationally and financially.

Ministerial and Parliamentary approval frameworks

• The Agreement itself required approval by the Commonwealth Parliament and the Parliaments of the States for it to have effect (Schedule cl 2(1)). The Act supplies the New South Wales legislative approval required by that clause. Ministerial approvals under the Agreement are required for varied items, and the Minister is given a power to approve funds and certain types of work (Schedule cls 11-14, 22). Thus, the Act sits within the executive and parliamentary approval rules envisaged by the Agreement.

Industrial law and awards

• Section 8(6) states that the same terms and conditions of employment, including workers’ compensation and the same salaries and wages, shall apply to officers and employees employed by the Commissioner in connection with the Railway as those applicable to railways in South Australia. The section makes this applicable notwithstanding anything in any Act, award or industrial agreement. This has a direct interaction, and to some extent a displacement, of potentially conflicting NSW industrial regimes for those workers but the section applies the SA terms to employees of the Commissioner in NSW.

Local Courts and summary enforcement

• Section 8(5)(b) provides for recovery of penalties in a summary manner before the Local Court. That cross-references local court jurisdiction and its procedural rules.

Acquisition compensation and remedies

• The Act requires acquisition under Public Works Act powers (s 5(1)), and separately limits remedies to damages (s 4(3)). This combination interacts with acquisition compensation regimes and limits equitable relief for persons affected by work, while leaving compensation mechanisms available.

Financial and audit frameworks

• Schedule cls 14-19 set out certification, accounting, reporting and auditing regimes involving State Auditor-Generals and the Commonwealth Auditor-General. The Act therefore intersects with public finance and audit laws and practices governing how public funds are advanced, reported and audited.

Other Acts referenced

• Section 6(2) expressly disapplies provisions of the Public Works Act 1912, s 91, so that the SA constructing authority will not be compelled to make or maintain fences along the Railway. The Act also contemplates that certain matters are to be authorised "notwithstanding the provisions of any other Act" (s 4(1); s 6(1)). Those not‑withstanding clauses mean the Act can create specific exceptions to other statutory duties in the NSW framework for the narrow purpose of this railway project.

Taken together, the Act overlays an inter‑governmental contractual architecture onto existing State statutory regimes, importing South Australian statutory instruments into a New South Wales location and using NSW PWA acquisition procedures while insulating works from injunctions. The result is cross‑jurisdictional legal pluralism anchored by ministerial and parliamentary approvals and tightly tied to specified audit and financial safeguards.

The Act text as provided contains limited explicit amendment metadata. The statutory text records insertions and amendments to s 8: the note below s 8 states "s 8: Ins 1969 No 26, sec 2. Am 2001 No 121, Sch 2.26; 2007 No 94, Sch 2." This indicates the following history, as captured by the instrument itself:

• s 8 was inserted in 1969 by the instrument cited as 1969 No 26, sec 2. The original Act is from 1968; the insertion in 1969 suggests an early amendment to add or restate s 8.
• Subsequent amendments to s 8 were made in 2001 (2001 No 121, Sch 2.26) and 2007 (2007 No 94, Sch 2). The Act text indicates these amending instruments affected s 8, though the Act as reproduced here includes the current form of s 8, and does not specify the precise textual changes effected by each amending instrument inside the reproduced text.

The Schedule (Agreement) is dated 2 October 1968 and records the commitments and allocations as executed at that date. The Schedule also rescinds clause 23 of the 1949 Agreement (Schedule cl 23), which is an internal amendment of the earlier inter-governmental contract.

No other amendment chronology is provided in the text of the Act supplied. The Act also repeatedly refers to the Public Works Act 1912 "as subsequently amended" (s 5(1); s 6(1); Schedule cl 3(2)(b)), which recognises that the PWA may have subsequent amendments that affect the operation of the acquisition and constructing authority powers invoked here.

A user requiring a complete amendment history for the Act should consult official legislative revision histories or the NSW legislation register to obtain a fully dated sequence of amendments, including the texts and operative dates of the 1969 insertion and the 2001 and 2007 amendments referenced, and any changes after 2007. The Act as printed here displays the current consolidated s 8 and indicates those amendment instruments by shorthand notation only.

The Act and its Schedule, as reproduced, do not cite any judicial decisions or report any litigation history. The instrument itself contains a statutory bar on injunctions for claims related to construction and execution of the Agreement (s 4(3)), which will materially affect the shape of any litigation arising from the project by removing a commonly used interlocutory remedy. Where litigation has occurred, the Act text does not record it.

Practical consequences for litigation risk and avenues

• The Act channels dispute remedies toward damages or compensation rather than injunctive relief (s 4(3)). This changes litigation strategy: plaintiffs cannot (under the statute) obtain an injunction to stop or delay construction; they must pursue monetary relief. That will influence the cost structure and tactical approach of potential litigants seeking to restrain works.
• Enforcement of by‑laws and summary penalties is to proceed in Local Courts under the extended SA Railways Act provisions applied by s 8(5)(b). If disputes arise over the application of those by‑laws or their extension into NSW, the Local Court forums and summary procedures will be the immediate enforcement pathway provided by the Act.
• Administrative remedies are relevant because payments by the Commonwealth are contingent on Ministerial approval and certification (Schedule cl 14): disputes about whether expenditure qualifies for Commonwealth funding may generate administrative law challenges to Ministerial decisions, but the text does not describe or limit judicial review avenues for those decisions.

Because the statutory text contains no reported litigation, readers who need to know whether courts have interpreted key provisions,particularly the scope of s 4(3)’s injunction bar, the cross‑jurisdictional application of SA law in NSW under s 8, or the evidentiary rules in s 8(5)(c)-(d),must search case law databases and court records. The Act itself does not authorise, report on, or summarise any judicial interpretation.

The Act contains several provisions that have practical, implementation and legal implications which may be easily overlooked. The following are concrete “gotchas” grounded in the text.

1. Injunctions are statutorily proscribed (s 4(3))

• If a party’s remedy strategy depends on equitable relief to prevent or delay construction, the Act blocks that route. Claims “directly or indirectly related” to construction or execution of the Agreement are limited to damages or compensation only, and no injunction can be granted which would prevent or restrict any person carrying out work authorised by the Act or the Agreement. This shifts dispute resolution to monetary compensation and can substantially reduce the bargaining power of affected parties during construction.

2. Soil, land and jurisdictional transfer (s 5(2))

• Land acquired in New South Wales is vested in the South Australian Railways Commissioner. Practically, this places land in New South Wales within the property regime of the SA Commissioner, but the Act also states that land acquired for public roads or services unconnected with the Railway is excluded from vesting. The vesting of NSW land in an SA statutory authority may raise questions in dealings with local governments, rates, planning instruments and land disposal rules, though s 8(4) restricts disposal of vested land without Governor approval.

3. South Australian law applies in New South Wales operations (s 8(2)-(6))

• The Commissioner may operate the Railway in accordance with the Agreement and “any law applicable or incidental” to operation of railways vested in the Commissioner under the South Australian Railways Commissioner’s Act 1936. That effectively imports SA regulatory, managerial and employment norms into operations undertaken in NSW territory. The employment provision (s 8(6)) applies SA wages, working conditions and workers’ compensation “notwithstanding anything contained in any Act, award or industrial agreement,” which could conflict with NSW industrial settings for workers engaged on the Railway.

4. Ministerial discretion matters (Schedule cls 3(1)(d)-(f), 11-14, 22)

• Conversion of private sidings and privately owned tank cars and certain rolling stock work require Ministerial approval. Commonwealth funding is payable only to expenditures approved or ratified by the Minister (Schedule cl 14(2)). The Minister also has approval and variation powers in the Schedule (cl 3(3)). Strategic actors cannot rely on automatic funding or approvals; they face variable ministerial discretion.

5. Commonwealth funding caps and SA repayment obligation (Schedule cls 13, 16)

• The Commonwealth’s financial exposure is not open-ended; cl 13 specifies caps for certain categories (for example, $400,000 for part of the work described in cl 3(1)(c), and per-siding or per-car contributions up to one-half of conversion costs as the Minister approves). South Australia must repay 30 per cent of Commonwealth payments by 50 equal annual contributions plus interest (Schedule cl 16). The who‑pays calculus is complex: the Commonwealth fronts funds but SA has a substantial long-term repayment obligation that may affect SA’s long‑term fiscal position.

6. Evidence and proof favour administrative actors (s 8(5)(c)-(d))

• A document purporting to be an appointment signed by the Commissioner is sufficient evidence of appointment to recover penalties, and a Government Printer copy of the SA Act or by‑laws is treated as sufficient evidence of content and force. These procedural shortcuts reduce the evidentiary burden on enforcement actors and can make contesting such proceedings more difficult for defendants.

7. Tendering obligation has an exception judged by the Minister (Schedule cl 8)

• The instruction to invite public tenders is subject to the Minister being satisfied that tendering is undesirable. This creates a possible threshold where procurement transparency can be reduced if the Minister accepts an exception, and a State itself may tender for work. The discretion to judge desirability of public tendering may be a locus for procurement disputes or allegations of unfairness.

8. Validation of prior works may bar undoing (s 4(2))

• Works and acts performed before the commencement of the Act are validated. Parties who might have argued procedural defects to earlier work may find their causes of action closed or limited to damages.

9. Disposal of vested land constrained by Governor approval (s 8(4))

• The Commissioner cannot dispose of vested land except with the Governor’s approval, which constrains asset monetisation or disposal strategies and embeds executive approval in future transactions.

10. Cross-application of prior agreements (Schedule cls 12, 23)

• The Schedule allocates rolling stock expenditure between the 1949 Agreement and this Agreement (88/12 split) and rescinds clause 23 of the 1949 Agreement. Practitioners must track provisions in both agreements to understand funding and scope for rolling stock conversions; the interlocking agreements introduce accounting and legal complexity.

These “gotchas” are direct consequences of specific clauses and have operational, commercial and procedural implications that implementers, legal advisers and affected private parties must explicitly address in project planning and risk allocation.

Compliance under the Act and the Agreement is largely administrative, documentary and procedural, layered by ministerial approvals and audit regimes. The following practical checklist is grounded in the Act’s text and the Schedule.

1. Project authorisations and approvals

• Ensure the Ministerial approvals required by the Agreement are obtained before incurring expenditures intended to be recoverable from Commonwealth funds: conversions of private sidings and privately owned tank cars (Schedule cl 3(1)(d),(e)), construction or conversion of rolling stock (cl 3(1)(f)), and any payments not otherwise provided for (cl 11(4)). Obtain written ministerial approvals and keep them with payment applications.

2. Planning, master plans and specifications

• Prepare and retain master plans, plans and specifications, and cost estimates in the form required by Schedule cl 5(a)(i)-(iii). Provide copies to the Minister and to the other State where required. Where variations to the Schedule’s standards are proposed, secure Ministerial approval and the concurrence or request of the relevant State as necessary (Schedule cl 3(3)).

3. Tendering and contracting

• Invite public tenders for work unless the Minister is satisfied it is undesirable (Schedule cl 8). Document the Minister’s satisfaction where tendering is not used, and ensure transparent procurement records that will fit audit scrutiny. If a State tenders, document conflict-of-interest mitigation and procurement compliance.

4. Land acquisition and vesting

• For land acquisition in NSW, follow the Public Works Act 1912 procedures as the text requires (s 5(1)). Record resumptions, appropriations and acquisitions carefully, and prepare transfer instruments vesting land in the South Australian Railways Commissioner (s 5(2)). Identify and exclude land acquired for public roads or services unconnected with the Railway as per s 5(2).

5. Certification and documentation for payments

• For any Commonwealth payment claim, prepare statements of expenditure certified both by the relevant Commissioner that the work complied with construction standards and by the State Auditor-General that expenditure was properly made in accordance with the Agreement (Schedule cl 14(4)). Retain originals of certifications and supporting ledgers, invoices, contracts and reports required for auditing.

6. Accounting, reporting and audit compliance

• Maintain full accounts and records of all financial transactions, work done, plant and materials used or disposed of in connection with the work (Schedule cl 18(a)). Furnish quarterly progress reports and financial statements to the Minister (Schedule cl 18(b)). Cooperate with State Auditor-General audits and be prepared to supply reports and to participate in the reporting regime to the Commonwealth Auditor-General (Schedule cl 19).

7. Inspection readiness

• Permit persons authorised by the Minister to inspect the work and related documents (Schedule cl 9). Have inspection packs ready with master plans, specifications, tenders, accounts and records for review on short notice.

8. Employment and industrial arrangements

• Apply South Australian employment terms, salary/wage rates and workers’ compensation arrangements to officers and employees engaged on the Railway (s 8(6)). Ensure payroll, contracts and human resources practices reflect SA terms to avoid disputes, given the "notwithstanding" phrasing in s 8(6).

9. Regulatory compliance and enforcement readiness

• Apply the SA by‑laws and regulations as extended (s 8(5)(a)) and ensure appointment letters for authorised enforcement officers are signed by the Commissioner and available for production in penalty proceedings (s 8(5)(c)). Maintain copies of SA by‑laws and regulatory texts as printed by the SA Government Printer, with dates, for evidentiary use (s 8(5)(d)).

10. Financial caps and repayment planning

• Track Commonwealth funding caps in Schedule cl 13 and ensure project budgets do not rely on funding beyond those caps without express Ministerial approval. For South Australia, prepare repayment schedules reflecting the obligation to repay three-tenths of Commonwealth payments over fifty years with interest tied to the Commonwealth’s long-term loan rate at the time (Schedule cl 16). Build the repayment obligation into long-term fiscal and cash‑flow planning.

11. Dealing with affected third parties

• For private landowners and operators affected by acquisition or conversion proposals, prepare compensation packages and communications that reflect the prohibition on injunctive relief and the availability of damages or compensation only (s 4(3)). Use robust valuation, compensation negotiation and dispute resolution mechanisms since interlocutory court intervention is limited.

12. Documentation of Ministerial decisions and variations

• Keep contemporaneous records of any Ministerial conferences with State Ministers (Schedule cl 22), approvals given, variations to the Schedule (cl 3(3)), and reasons when the Minister exercises discretion on tendering exceptions (Schedule cl 8) or funding decisions. These documents will be central to defending funding claims and responding to audit queries.

13. Disposal and asset management approvals

• Recognise that the Commissioner cannot dispose of vested land without Governor approval (s 8(4)). For any proposed disposal, prepare Governor-submission materials, valuations and legal instruments in anticipation of the approval requirement.

14. Legal strategy for disputes

• Because injunctive relief is barred for matters related to construction (s 4(3)), legal advisers should prioritise valuation, compensation and administrative-review claims over injunction strategies. For administrative decisions (Ministerial approvals), consider judicial review avenues where appropriate, but account for the statutory framework that directs funding and approval discretion.

Following these steps will align project operations with the statutory and contractual architecture of the Act and the Agreement. Proper records, certifications, timely reporting, and clear ministerial approvals are the critical compliance pillars under the statutory scheme.
