Home Affairs Act 2023

The Act uses a small number of tightly defined legal concepts to produce its effects. Those concepts and their immediate legal consequences under the Act are as follows.

• Land and relevant lease: “land” is a precisely described parcel in Yarralumla, defined by plan reference (s 4). A “relevant lease” is any lease owned or held in respect of that land at the commencement of the Act (s 4). The Act therefore operates only in respect of existing leases at the moment the Act commences; it does not retrospectively create or affect leases granted after commencement.

• Termination by operation of the statute: section 5 provides that a relevant lease, and a broad list of related legal and equitable interests and instruments, “is terminated by force of this section on the commencement of this section.” The termination is automatic on commencement; the Act does not require notice, registration, or further action to bring the termination into effect. The list in s 5 expressly includes rights and instruments “granted or arising under or pursuant to a relevant lease, or in dependence on a relevant lease,” which captures secondary and contingent interests such as charges, mortgages and licences.

• Acquisition and just terms: section 6 anchors the compensation mechanism to paragraph 51(xxxi) of the Constitution by defining “acquisition of property” and “just terms” with the same meaning as in that constitutional provision (s 4 definitions). Section 6(1) then provides that if the Act’s operation would result in an acquisition of property to which paragraph 51(xxxi) applies from a person otherwise than on just terms, the Commonwealth is liable to pay a reasonable amount of compensation. The Act does not independently define “reasonable” beyond that constitutional definitional linkage.

• Remedies for disagreement on compensation quantum: s 6(2) gives the person entitled to compensation a statutory right to institute proceedings in the High Court or the Federal Court for recovery of such reasonable amount as the court determines. The Act does not prescribe valuation methodology, time limits for commencing proceedings, interlocutory relief options, or administrative claim processes; it places quantum disputes before the federal courts.

• Parliamentary primacy over other laws: section 7 contains an express non‑derogation clause stating that the Act operates “despite any other law of the Commonwealth or of a State or Territory (whether written or unwritten)” and applies “despite any rights, duties, obligations, powers, limitations, offences, privileges or immunities” that would otherwise apply (s 7(1)-(2)). The subsection lists particular statutes, including the Australian Capital Territory (Planning and Land Management) Act 1988 and several statutes dealing with diplomatic and consular privileges and immunities, but also preserves the land’s status as National Land under s 27 of the ACT Planning and Land Management Act 1988 (s 7(3)). The s 7 list treats both written and unwritten laws and rights as subject to the Act’s overriding effect, subject only to the stated preservation.

• Binding the Crown and administrative responsibility: s 3 states that the Act binds the Crown in each of its capacities. The enacting apparatus identifies the Minister for Home Affairs as the administering Minister. The Act therefore expressly applies to the Crown (s 3) and is to be administered by the Home Affairs portfolio (enacting words), though it does not create a compensation-disbursement or claims-administration regime.

These concepts combine to produce a legal mechanism where statutory termination of leases converts a bundle of private and contingent rights into a claim for “reasonable compensation” under the constitutional standard, with resolution by agreement or by the federal courts.

The Act identifies a narrow class of persons and interests directly affected, and a wider set of indirectly affected stakeholders. Who is affected, and how, follows from the text.

Directly affected persons and entities

• Holders of “relevant leases” in respect of Block 26, Section 44, Yarralumla at the time the Act commences (s 4, definitions; s 5). A relevant leaseholder loses its lease by operation of s 5 on commencement.

• Holders of legal or equitable rights that are “granted or arising under or pursuant to a relevant lease, or in dependence on a relevant lease” (s 5). That list is comprehensive and expressly includes trusts, restrictions, obligations, mortgages, encumbrances, contracts, licences and charges. In practice, mortgagees holding security over the lease, licencees occupying under a sub‑lease or licence dependent on the lease, and contractors with rights flowing from the lease will be directly affected because their interests are terminated if they are in dependence on the lease.

• Persons with contingent or prospective rights that are dependent on the relevant lease at commencement. The s 7 overriding clause expressly addresses contingent and prospective rights among the rights that the Act displaces (s 7(1)(b); s 7(2)). If a right is contingent on the lease existing at commencement, s 5 will terminate that dependent right.

Indirectly affected persons and entities

• Counterparties to contracts that rely on the lease or on ongoing occupation of the premises covered by the lease. Contracts for services, supply or use that assume the lease continues may be discharged, frustrated or rendered unfulfillable by the termination of the lease; the Act itself does not provide contractual remedies beyond compensation for acquisition where constitutional principles apply (s 6).

• Mortgagees, charge-holders and financiers: mortgages and charges “in dependence on a relevant lease” are terminated by s 5. Those lenders may have claims for compensation under s 6 if the termination results in an acquisition of property to which paragraph 51(xxxi) applies and is not on just terms.

• The Commonwealth and administering Minister: the Commonwealth is the paying entity for compensation liabilities under s 6(1). The Act is expressed to be administered by the Minister for Home Affairs (enacting words and Act title). The Commonwealth also gains the immediate legal effect of termination and the ability to rely on the overriding clause (s 5; s 7).

• Territory and local governments and statutory agencies: s 7 expressly states the Act has effect despite State or Territory laws and lists specific Territory statutes that are subject to the overriding effect (s 7(2)(a)-(i)), although s 7(3) preserves the land’s status as National Land under s 27 of the ACT Planning and Land Management Act 1988. That means Territory planning and other statutory regimes are displaced to the extent inconsistent, and planning or administrative processes that would otherwise apply cannot be used to preserve rights affected by this Act.

• Persons with potential proceedings or defences under the listed statutes (for example, under diplomatic or consular immunities statutes): s 7(2)(b)-(i) makes clear the Act operates despite those statutes.

Who pays and who decides

• The Commonwealth is the party that is liable to pay compensation under s 6(1) where the acquisition ground is established. If there is disagreement on quantum, the person entitled to compensation may institute proceedings against the Commonwealth in the High Court or the Federal Court (s 6(2)).

• The Act is administered by the Minister for Home Affairs (enacting words). The Act itself does not prescribe procedures for assessment, notice or payment: the courts are the forum for quantum disputes (s 6(2)).

Who is not affected by the Act

• Persons holding interests in the land that are not granted under, pursuant to, or in dependence on a relevant lease at commencement would not be terminated by s 5, subject to the breadth of the “in dependence on” formulation. The Act also does not purport to affect leases granted after commencement.

• The Crown’s status is preserved from being exempted from the Act: s 3 binds the Crown; the Act does not carve out government use.

Overall, the statutory architecture concentrates immediate legal effect on the existing leaseholders and anyone whose legal or equitable interest depends on those leases. Financial institutions and contractual counterparties stand to be materially affected because instruments securing economic value by reference to the lease are within the termination scope (s 5). The Commonwealth bears the budgetary exposure for compensation claims, and affected persons are directed to the federal courts for resolution of disputes about compensation quantum (s 6).

The Act creates rights and obligations of a particular, narrow kind. It does not create a broad regulatory regime; it effects termination of interests and a compensatory right anchored to constitutional acquisition law. The operative duties and rights are as follows.

Rights conferred by the Act

• Right to compensation: s 6(1) creates a right in any person from whom property has been acquired by operation of the Act to be paid a reasonable amount of compensation where paragraph 51(xxxi) applies and the acquisition is otherwise than on just terms. That right arises directly from the statute and is expressed in terms consistent with the constitutional protection.

• Right to litigate for quantum: s 6(2) provides a right to institute proceedings in the High Court or the Federal Court to recover such reasonable amount of compensation as the court determines. The statutory right confers jurisdictional access to federal courts for compensation disputes with the Commonwealth.

Duties imposed or implied by the Act

• Commonwealth payment obligation: where the test in s 6(1) is satisfied, the Commonwealth is liable to pay a reasonable amount of compensation. The Act thus imposes an obligation on the Commonwealth to pay compensation for constitutionally cognisable acquisitions that are otherwise than on just terms. The Act does not specify the administrative process for determining or paying that compensation; the obligation may be honoured by agreement or enforced by court judgment under s 6(2).

• Immediate legal consequence of termination: while not described as a duty, the Act imposes an immediate legal status change , termination of leases and dependent interests , that imposes practical duties on parties (for example, lessees must vacate or adjust their operations; landlords and licensees must cease reliance on the terminated instruments). Those duties, insofar as they exist, arise from common law and contract law consequences of losing title or contractual basis, not from an express statutory compliance regime in this Act.

Administrative and procedural features

• No administrative claims mechanism: the Act does not create administrative claim procedures, valuation processes, dispute resolution frameworks, time limits to make claims, notice requirements, or specified forms of payment. Instead s 6(2) provides court access to determine quantum where agreement is not reached. That means affected persons who seek redress have a right to litigate but no statutorily prescribed pre-litigation administrative path is established.

• Preservation of National Land status: while the Act overrides other laws generally (s 7(1)-(2)), s 7(3) explicitly preserves the land’s status as National Land under s 27 of the ACT Planning and Land Management Act 1988. That preservation is a right of continuity for the statutory designation of the land and may carry procedural or administrative consequences under that Act, albeit the Act does not itself create duties flowing from that preservation.

Express exclusions and bounds

• The definitions in s 4 adopt the constitutional meanings of “acquisition of property” and “just terms” (s 4). The Act’s compensation duty is therefore framed by constitutional doctrine, not by a separate statutory regime. This bounds both the Commonwealth’s liability and the scope of persons who can claim compensation, because compensation is triggered only if there is an acquisition to which paragraph 51(xxxi) applies and that acquisition is otherwise than on just terms (s 6(1)).

• The Act binds the Crown in each capacity (s 3), meaning the Crown cannot claim immunity from the Act’s effects.

In sum, the Act confers the right to compensation in constitutionally-relevant cases and the right to litigate for quantum, while imposing an obligation on the Commonwealth to pay a reasonable amount in those cases. It imposes immediate legal change by terminating the specified leases and dependent interests, but it does not establish an administrative compensation apparatus or statutory timelines; recourse to federal courts is the statutory default for unresolved compensation disputes.

The Act does not create criminal offences, administrative sanctions, or an enforcement agency role beyond the declaratory and compensatory provisions. Its enforcement architecture is primarily civil and judicial, not penal. Key points are:

Absence of criminal penalties or regulatory sanctions

• The text contains no offence provisions, monetary penalties for non-compliance by private parties, or enforcement mechanisms directed at private conduct. There is no administrative penalty scheme, no power to impose fines, and no express enforcement agency conferred with coercive powers in the Act.

Judicial enforcement of compensation claims

• The primary enforcement mechanism for unresolved compensation claims is litigation in the federal courts. Section 6(2) gives an affected person the statutory right to institute proceedings in the High Court of Australia or the Federal Court of Australia to recover a reasonable amount of compensation from the Commonwealth if the parties disagree on quantum. That provision directs compensation disputes to the courts and effectively enforces the Commonwealth’s liability through judicial determination.

• There is no express statutory limit on the choice of forum between the High Court and the Federal Court; both are named. The Act does not set time limits, procedures, or interlocutory remedies. Standard court practice and rules will therefore govern pre-hearing procedures, injunctive relief applications, discovery, valuation evidence, and remedies for delay or interim needs.

Operation of the overriding clause as instrumental enforcement

• Section 7 gives the Act effect “despite any other law” and applies “despite any rights, duties, obligations, powers, limitations, offences, privileges or immunities” under other laws (s 7(1)). The practical effect is to remove inconsistent legal defences or procedural obstacles that might otherwise arise under State, Territory or Commonwealth law, subject to the narrow preservation in s 7(3). This function is not an enforcement penalty but operates to prevent other laws from precluding the statutory effect of termination and the Commonwealth’s ability to rely on the Act.

Remedies available to affected persons beyond compensation

• The Act does not specify other civil remedies such as statutory conversion payments, reinstatement, specific performance, or equitable relief in respect of the termination of leases. Affected persons may pursue equitable or contractual remedies where available at law, but those remedies will be constrained by the Act’s automatic termination of the lease and the s 7 overriding clause, and by the need to show that a common law remedy remains available despite the statutory termination. The Act itself does not create or preserve such remedies.

Budgetary and fiscal enforcement considerations

• The Commonwealth bears the financial exposure for compensation under s 6(1). There is no statutory provision detailing appropriation, payment timing, or budgeting for compensation liabilities. Financial enforcement of a court-ordered compensation judgment would proceed against the Commonwealth as a sovereign debtor, subject to the usual Commonwealth payment mechanisms and judgment enforcement law, but the Act contains no special enforcement process or penalties directed at the Commonwealth.

Summary

• Enforcement is civil and judicial: affected persons enforce compensation entitlements by suing the Commonwealth in federal court (s 6(2)). The Act contains no penal provisions. The overriding clause reduces the room for other legal defences grounded in conflicting legislative or common law rights (s 7), but it does not itself create coercive private enforcement mechanisms or penalties. The Crown is bound by the Act (s 3), and the Commonwealth is the payer of compensation where constitutionally required (s 6(1)).

The Act expressly addresses its interaction with other laws and certain statutory regimes; those provisions determine much of the Act’s legal effect and the practical availability of other legal protections. The interaction points are statutory and textual.

Express non‑derogation and precedence (s 7)

• Section 7(1) states the Act has effect “despite any other law of the Commonwealth or of a State or Territory (whether written or unwritten)” and “applies despite any rights, duties, obligations, powers, limitations, offences, privileges or immunities” which would otherwise apply. That is an express legislative statement of precedence, putting the Act at the top of the relevant legal hierarchy for matters within its scope.

Specific statutes listed (s 7(2))

• Section 7(2) lists statutes that the Act operates “despite” (and expressly includes “any regulations or other legislative instruments made under them”). The listed statutes include:

  • the Australian Capital Territory (Planning and Land Management) Act 1988, subject to subsection (3) (s 7(2)(a));
  • the Autonomous Sanctions Act 2011 (s 7(2)(b));
  • the Consular Privileges and Immunities Act 1972 (s 7(2)(c));
  • the Diplomatic Privileges and Immunities Act 1967 (s 7(2)(d));
  • the Foreign States Immunities Act 1985 (s 7(2)(e));
  • the International Organisations (Privileges and Immunities) Act 1963 (s 7(2)(f));
  • the Overseas Missions (Privileges and Immunities) Act 1995 (s 7(2)(g));
  • the Seat of Government (Administration) Act 1910 (s 7(2)(h));
  • the Australian Capital Territory National Land (Leased) Ordinance 2022 (s 7(2)(i)).

• The listing makes clear that to the extent those statutes (and subordinate instruments under them) would produce inconsistent rights, duties or immunities in respect of the land or the leases, the Home Affairs Act takes precedence.

Preservation of National Land status (s 7(3))

• Subsection 7(3) qualifies the overriding effect by stating that “Nothing in this Act affects the status of the land as National Land under section 27 of the Australian Capital Territory (Planning and Land Management) Act 1988.” Thus, while the Act displaces many legal effects of other laws, it leaves intact the statutory designation of the parcel as National Land under s 27 of the ACT Planning and Land Management Act 1988. The Act therefore removes inconsistent private or statutory interests that depend on leases but preserves the land’s statutory category.

Treatment of compensation relative to sanctions law (s 7 note)

• A legislative note appended to s 7 states that “As a result of this section, any compensation paid under section 6 would not be subject to the Autonomous Sanctions Act 2011.” That indicates the Act contemplates that compensation obligations under s 6 are to be free of interference from the Autonomous Sanctions Act 2011, which is otherwise listed among the statutes “despite” which this Act operates (s 7(2)(b)). The note is not itself operative law but reflects the intended legal consequence of the overriding clause in relation to that statute.

Definitions tied to the Constitution (s 4)

• The Act’s definitions of “acquisition of property” and “just terms” adopt the meanings in paragraph 51(xxxi) of the Constitution (s 4). This establishes interplay between the Act and constitutional property acquisition doctrine. Whether the operation of the Act amounts to an “acquisition” under the Constitution will be a question of constitutional law. The Act does not define just terms or prescriptive valuation methodology; it relies on constitutional standards and court determination.

Binding the Crown (s 3)

• Section 3 states the Act binds the Crown in each of its capacities. That removes the possibility of Crown immunity as an obstacle to the statutory effects, and ensures the Commonwealth is treated as subject to the Act’s obligations, including the compensation liability under s 6(1).

Practical consequences of the interaction

• To the extent that State or Territory law would have protected a lease, prevented termination, or provided alternative remedies, s 7 reduces that protection by giving the Act precedence (s 7(1)). The Act therefore narrows the scope of other statutory or common law defences that could otherwise be relied upon.

• The preservation of National Land status (s 7(3)) may mean that aspects of the ACT planning and land management framework still apply to the parcel’s designation, but not in a way that prevents the statutory termination of leases or the Commonwealth’s ability to rely on this Act where inconsistent.

• Because the Act ties compensation rights to constitutional acquisition doctrine (s 4; s 6), the Act interacts with constitutional law processes and the federal court system, rather than with ordinary administrative compensation schemes.

In short, the Act operates as a targeted, high-precedence statutory instrument that displaces conflicting State, Territory and Commonwealth law in relation to the defined parcel and the dependent leases, while preserving the land’s statutory status under the ACT Planning and Land Management Act and framing compensation claims within constitutional acquisition principles.

The source text contains only the Act as enacted and a commencement table; there are no subsequent amendments recorded in the provided material. The Act itself includes a commencement table and an explicit note about the table’s content. Relevant textual points are:

• Commencement: The Act’s commencement provisions specify that “the whole of this Act” commences “Immediately after this Act receives the Royal Assent” with the timestamp recorded as 4.26 pm (A.C.T.) 15 June 2023 (s 2 commencement table). That means the statutory termination in s 5 took effect at that moment.

• Note on the commencement table: The Act includes a formal editorial note stating: “This table relates only to the provisions of this Act as originally enacted. It will not be amended to deal with any later amendments of this Act.” That signals the text provided is the original enactment and that the table is fixed as enacted, not updated to reflect later amendment chronology. No later amendments are recorded in the provided material.

• No amending instruments included: The Act as supplied contains no provisions amending other Acts, no schedules amending statutes, no transitional provisions apart from the termination on commencement, and no sunset clause. The Act’s scope and mechanisms are self-contained and immediate.

• No savings or transitional clauses beyond s 5 and s 7(3): The Act terminates relevant leases on commencement (s 5) and preserves the land’s status under the ACT Planning and Land Management Act (s 7(3)). There are no other transitional provisions, savings clauses, or staged implementation provisions in the provided text.

• Legislative note on future changes: The statement in s 2(2) that “Any information in column 3 of the table is not part of this Act. Information may be inserted in this column, or information in it may be edited, in any published version of this Act.” is an editorial instruction about the commencement table’s marginal content and does not itself reflect an amendment to the substantive law.

Given that the supplied text is the Act as originally enacted and no subsequent amending legislation is present in the source, the amendment history in the provided material is limited to the initial enactment and commencement on 15 June 2023. Any future amendments, repeal, or consequential changes are not recorded in the source material supplied.

The source text does not record any litigation history. The Act provides a statutory route for litigation in compensation disputes (s 6(2)), but the document itself contains no account of cases, judgments, or proceedings arising from the Act. Key points relevant to potential litigation are:

• Court forum for compensation disputes: Section 6(2) expressly permits a person who does not agree with the amount of compensation to institute proceedings in the High Court of Australia or the Federal Court of Australia for recovery of a reasonable amount of compensation as the court determines. The Act therefore contemplates litigation as the mechanism for resolving disputes about compensation quantum.

• No recorded cases or judicial interpretations in the source: The provided text includes no judicial decisions, no recorded test cases, and no guidance from courts interpreting the Act. There is therefore no litigation history available in the source material to draw upon.

• Constitutional issues likely to arise in litigation: The Act ties compensation to paragraph 51(xxxi) of the Constitution by adopting the constitutional meanings of “acquisition of property” and “just terms” (s 4) and by providing compensation when the Act’s operation results in an acquisition otherwise than on just terms (s 6(1)). Potential litigated issues, to be decided by courts, would concern whether the operation of s 5 amounts to an “acquisition” of property within the constitutional provision and, if so, whether “just terms” were provided. The Act itself leaves these questions to the courts; no judicial determinations are recorded in the source.

• No procedural rules or timelines in the Act: There is no statutory limitation period, prescribed valuation methodology, or procedural requirement for lodging claims in the Act. Litigation strategy and procedure would therefore be governed by the rules and practice of the High Court or the Federal Court and relevant general law doctrines.

• Note of possible issues for litigators: Because the Act displaces other laws (s 7), litigation may involve issues about the effect of the overriding clause on defences or alternative remedies that might have existed under State, Territory or other Commonwealth law. The Act’s preservation of National Land status (s 7(3)) may raise questions about the relationship between statutory designation and the availability of particular remedies, but the provided material contains no case law addressing these issues.

In sum, while the Act creates statutory entitlement and a litigation route for compensation disputes (s 6(2)), the supplied source contains no litigation record. Any analysis of litigation patterns, outcomes or precedent would require consulting court records and judgments, which are not part of the provided text.

A number of traps, timing risks, and practical consequences are visible directly from the Act’s wording. These are matters that practitioners and affected parties should note because they follow from the statutory text rather than external context.

Immediate and automatic termination

• Section 5 terminates relevant leases and a broad list of dependent interests “by force of this section on the commencement of this section.” There is no statutory notice period, negotiation mechanism, or administrative process to preserve rights pending compensation. The termination is effective immediately upon the commencement timestamp (s 2). Parties cannot rely on future administrative steps to preserve contractual or proprietary arrangements once the Act commences.

Breadth of terminated interests

• The list in s 5 is intentionally wide and includes “any legal or equitable right, title, interest, trust, restriction, obligation, mortgage, encumbrance, contract, licence or charge” that is “granted or arising under or pursuant to a relevant lease, or in dependence on a relevant lease.” That breadth means security interests, mortgages and charges that are expressed to rely on the lease are extinguished, potentially exposing creditors to loss. Careful factual analysis is required to determine whether an instrument is truly “in dependence on” the lease or stands independently.

No administrative claims pathway or valuation method

• Section 6(1) requires the Commonwealth to pay “a reasonable amount of compensation” where the operation of the Act results in a constitutionally cognisable acquisition otherwise than on just terms. The Act does not establish a statutory process for assessing, agreeing, or paying that compensation. There is no statutory timeline for start-to-finish determination, no interim payment mechanism, and no requirement the Commonwealth engage independent valuers prior to litigation. Disputes therefore default to federal court litigation (s 6(2)), which can be costly and time-consuming.

Constitutional threshold for compensation

• Compensation under s 6 is triggered only if there is an “acquisition of property to which paragraph 51(xxxi) of the Constitution applies” and the acquisition is “otherwise than on just terms” (s 6(1)); the Act adopts the constitutional meanings of these terms (s 4). The existence of a compensable acquisition is therefore not automatic for every terminated interest; it depends on constitutional doctrine as applied by the courts. Some terminated interests may not amount to an “acquisition” within paragraph 51(xxxi), and consequently no statutory compensation obligation will arise for them.

Overriding effect against other laws, including immunities

• Section 7 operates “despite” other Commonwealth, State and Territory laws, including statutes dealing with diplomatic and consular privileges and immunities (s 7(2)(b)-(g)). Parties who might otherwise have invoked those statutes to protect interests should note that the Home Affairs Act expressly displaces inconsistent protections. The Act states this operation is subject to s 7(3), but the overriding effect is otherwise broad.

Preservation of National Land status only

• Section 7(3) expressly preserves the land’s status as National Land under s 27 of the ACT Planning and Land Management Act 1988. That preservation may have administrative or planning consequences, but it does not prevent the immediate statutory termination of leases or the Commonwealth’s compensation obligations. Parties should not infer that other procedural or contractual protections survive because the National Land status is preserved.

Binding the Crown

• The Act binds the Crown in each of its capacities (s 3). That means the Commonwealth cannot claim non‑application of the Act by virtue of Crown immunity. However, binding the Crown does not create a fast-pay mechanism for compensation , the statutory remedy is either agreement or court determination (s 6(2)). The practical risk for claimants is litigation delay and the need to secure enforceable judgments against the Commonwealth.

No express protection for third-party purchasers

• The Act terminates interests irrespective of third-party knowledge or registration status where those interests are in dependence on the lease. A third‑party purchaser or financier who acquires an interest that is dependent on the lease at or before commencement may find the interest terminated despite registration or payment. The Act does not provide a priority or indemnity mechanism for bona fide purchasers.

Note on the Act’s narrow geographic scope

• The Act applies to a single described parcel of land in Yarralumla. The narrow geographic scope is clear from the definition of land (s 4). However, the consequences for anyone with rights that depend on that land are immediate and broad.

Timing and urgent action imperative

• Because the Act commenced immediately on Royal Assent (s 2) and termination occurs by force of s 5 at commencement, affected parties who wished to preserve rights had only the period before Royal Assent to act. After commencement, the statutory termination is in force and the remedial path is compensation claims under s 6 or equitable/contractual causes that remain available despite the statute.

In short, the main “gotchas” are the immediacy of termination without administrative process, the breadth of terminated dependent rights (including charges and mortgages), the constitutional threshold for recoverable compensation, the absence of statutory claim procedures or interim payments, and the Act’s express precedence over a wide set of other laws. These features create concentrated legal and financial risk for lessees, financiers and contractual counterparties that depend on the lease.

Compliance for the different actors affected by the Act is a matter of recognising what the Act does and taking the available legal actions the statute contemplates. The Act itself contains no detailed compliance processes, so parties must act within the contours of the statutory text. Practical steps, grounded in the Act, are below.

For affected leaseholders and holders of dependent rights

• Identify whether the instrument is a “relevant lease” or “in dependence on a relevant lease.” Start by checking whether the lease was “owned or held in respect of the land at the commencement of this Act” (s 4 definition of relevant lease; s 5). For each instrument or contractual relationship, determine whether the continuing legal effect of the instrument is contingent on the lease. If it is, it falls within s 5’s termination scope.

• Preserve and gather documentary evidence. Compile the lease documents, any sub-lease agreements, licences, mortgage and charge documents, correspondence, valuation reports, contracts that rely on the lease, and proof of possession or occupation. Those materials will be central to any compensation negotiation or court proceeding under s 6(2) because the Act provides no administrative claim pathway.

• Quantify loss and prepare to prove acquisition. Because compensation under s 6(1) requires that the operation of the Act results in an acquisition to which paragraph 51(xxxi) applies and that the acquisition is otherwise than on just terms, affected parties should have valuation evidence and legal analysis ready to demonstrate acquisition and quantum. The Act leaves quantum determination to the courts if agreement is not reached (s 6(2)).

• Consider early litigation or interim relief where necessary. If immediate economic loss is severe and urgent relief is required, consider seeking interlocutory relief in the Federal Court or, where appropriate, the High Court. While the Act does not create a statutory interim payment mechanism, court orders (for example injunctive relief) could be a tool to manage particular disputes, subject to the Act’s termination by statute and the court’s assessment of the merits.

For mortgagees, financiers and charge-holders

• Review security documentation to determine whether the mortgage or charge is truly “in dependence on a relevant lease.” Where instruments are worded to secure a leasehold estate, the Act suggests such securities will be terminated by s 5. If a security interest was intended to be over a separate asset or had an independent operation not contingent on the lease, the position may differ.

• Reassess credit risk and provisioning. Prepare for the possibility that security will be extinguished and mitigation will need to be pursued either through compensation claims under s 6 or through contractual claims against borrowers or guarantors if appropriate and available.

For the Commonwealth and the administering Minister

• Prepare to receive and process compensation claims. Although the Act contains no administrative claim process, the Commonwealth, as the liable payer under s 6(1), should anticipate claims and be ready to litigate or negotiate. Budgetary planning for potential compensation liabilities is a corollary of the Act binding the Crown (s 3).

• Coordinate with relevant departments to document the statutory basis and to determine positions in any litigation under s 6(2). The Minister for Home Affairs is the administering Minister as indicated in the Act’s enacting words, so administrative responsibility will sit within that portfolio.

For State, Territory and local authorities

• Note the overriding effect and review relevant administrative processes. Section 7(1)-(2) means the Home Affairs Act operates despite State or Territory laws, including planning legislation listed in s 7(2). However s 7(3) preserves the land’s status as National Land under s 27 of the ACT Planning and Land Management Act 1988. Authorities should therefore review any interactions between the statutory designation and administrative functions relevant to the parcel, but should be aware the Act displaces inconsistent statutory or common law rights.

Procedural best practice for all affected parties

• Seek legal advice promptly. The Act’s immediacy and the absence of administrative processes mean legal advice is required to determine whether a claim exists under s 6 and how to prosecute or defend it.

• Preserve evidence of value and possession. This includes valuation reports, rental histories, service charge records, capital investment evidence and any contemporaneous communications that demonstrate interest, expectation, and loss. Courts will resolve quantum without statutory valuation guidance, so robust evidence will be necessary.

• Consider alternative dispute resolution where feasible. Although the Act places disputed quantum before the courts if agreement is not reached (s 6(2)), parties may be able to negotiate settlements with the Commonwealth to avoid litigation costs and delays.

• Monitor for statutory notices or administrative steps not provided in this Act. Because the Act provides no notice mechanism, check for any administrative guidance or consequential instruments issued by the administering Minister or Departments that may set out practical steps for claims or valuation procedures post‑enactment. Those actions would not be in this Act but may assist in practical compliance.

Summary checklist

1. Confirm whether the instrument is a relevant lease or dependent on a relevant lease (s 4; s 5).
2. Compile documentary evidence and valuation materials to support any compensation claim (s 6).
3. Consider immediate legal options, including commencement of proceedings in the High Court or Federal Court when quantum cannot be agreed (s 6(2)).
4. Mortgagees and financiers should review security positions and consider contractual remedies against borrowers where possible (s 5).
5. The Commonwealth should prepare for claims and budgetary consequences, and the administering Minister should coordinate response (enacting words; s 6(1)).

These steps flow directly from the Act’s text: termination on commencement (s 5), the constitutional link to compensation (s 4; s 6), and the court-based remedy for disputed quantum (s 6(2)).
