Several recurring definitions and structural devices determine how the Act operates. These concepts appear repeatedly across powers and procedural provisions; understanding them is necessary for identifying who decides, who pays, and what can be varied.

• Notice under this Act. The principal intervention mechanism is a “notice” issued by a Minister (or, for specified provisions, the Treasurer or Attorney‑General). Notices are the vehicle for altering the operation of other Acts and subordinate instruments (see ss 5-6, 13-21, 22-24). “Notice” is used throughout in the sense of a formal public instrument published in the Gazette (s 8(1)) and subject to parliamentary laying and committee scrutiny (s 7).

• Relevant emergency circumstances. A Minister may only issue many categories of notice if satisfied that “the relevant emergency circumstances exist” (s 5(1)-(2)). The statutory test is framed broadly and includes presence of the disease, risk of contraction, movement restrictions imposed by other instruments, reductions in available personnel for carrying out activities, and the desirability of ensuring supply of goods or services (s 5(2)(a)-(e)). For economic measures under ss 22 and 23, the Minister or Treasurer must be of the opinion that the economic effects of the emergency circumstances justify action (s 5(3)).

• Emergency manager. For many notices the Act requires approval by the “emergency manager” (s 6). The emergency manager is the State Controller when there is a declared state of emergency under the Emergency Management Act 2006 in relation to the disease, and otherwise the Director of Public Health (s 4 definition). That centralises operational approval in either the State Controller or the Director of Public Health depending on whether a state of emergency is declared.

• Relevant legislative instrument. The Act’s powers are mainly exercised by reference to another Act or an “instrument of a legislative character” (s 4). These are defined broadly to include Acts, regulations, rules, by‑laws and letters patent (s 4). Notices therefore operate by temporarily modifying the operation of other laws.

• Permit. The Act uses “permit” to include planning permits under the Land Use Planning and Approvals Act 1993 and other licences, certifications or authorities issued under a “relevant licensing Act” or prescribed class (s 4). Ministers may amend or revoke permit provisions for a period (s 14) and may declare that planning offences do not apply in specified areas where emergency management requirements justify on‑the‑ground activity (s 15).

• Emergency period and emergency cessation day. The Act uses “emergency period” (for example in s 22) with cross‑reference to the Residential Tenancies Act 1997 as amended by this Act; the Act requires the Director of Public Health to inform the Minister when emergency circumstances no longer exist and requires the Minister to declare an emergency cessation day within 90 days (s 27). Notices generally lapse by operation of s 8(3) sixty days after that day.

• Quarantine scheme concepts. Part 6A creates a discrete set of definitions and mechanisms: “quarantined person”, “quarantine direction”, “quarantine premises”, “quarantine period”, “accommodation agreement”, “quarantine debt amount”, “invoice”, “quarantine debt order”, “family debt amount”, and “responsible person” (s 25A). These definitions are tightly bound to the scheme that permits the Crown to serve an invoice on particular classes of quarantined persons and to impose specified per‑day charges subject to family calculations and caps (ss 25B-25F).

• Parliamentary and committee scrutiny. Notices must be laid before each House within three sitting‑days (s 7(1)) and copies (except for s 27(1) notices) must also be sent to the Subordinate Legislation Committee within 14 days (s 7(3)-(4)). The Act explicitly applies provisions of the Subordinate Legislation Committee Act 1969 and the Acts Interpretation Act 1931 to notices as if they were regulations (s 7(4)-(5)).

• Override and non‑application language. The Act repeatedly authorises actions “despite” other legislative instruments; examples include amending permits “despite any other relevant legislative instrument” (s 14) and authorising meetings, electronic actions, or exhibitions “despite any provision of a relevant legislative instrument” (ss 17-19). Conversely, s 26 removes the operation of s 18 of the Public Health Act 1997 in relation to actions under that Act for the disease.

These concepts combine to create a modular, temporary law‑altering mechanism: Ministers trigger effects by notice, the emergency manager vets most notices, Parliament and a scrutiny committee receive notices retrospectively, and targeted operational schemes such as the quarantine charging regime are managed by an appointed responsible person under order and invoice powers. Several definitions tie exercise of powers to specific dates (principally 31 July 2020) and to classes governed by separate orders, giving administrators discretion to specify who is captured by orders and invoices (ss 25A-25C, 25E).

The Act affects a wide set of actors in different ways. The statutory language identifies decision‑makers, administrators, private parties who may be subject to notices or invoices, and bodies whose procedures or statutory obligations may be temporarily altered.

Primary State decision‑makers and administrators

• Ministers. Ministers are the principal issuers of notices under the Act, subject to prerequisites. Most notices (except specified ones under ss 22, 23 or 27) require the issuer to be satisfied that the relevant emergency circumstances exist (s 5) and require emergency manager approval (s 6). The Premier retains administrative responsibility for the Act until administrative arrangements are otherwise specified (s 31).

• Treasurer. The Treasurer has specific power to issue notices limited to financial measures such as waiver, deferral or directions about calculation methods and rates for fees, taxes and charges payable under other instruments (s 23). The Treasurer also issues notices under s 22 only if satisfied that economic effects justify it (s 5(3)).

• Attorney‑General. The Attorney‑General alone may issue notices under s 20 to authorise courts, tribunals and entities to hold proceedings in the “approved manner” (s 20(1)). Those notices may only be issued on request from the relevant chief judicial or tribunal officer or entity head (s 20(3)).

• Emergency manager. For approval of many notices the emergency manager must consent (s 6). The emergency manager is the State Controller during a declared state of emergency relating to the disease, otherwise the Director of Public Health (s 4).

• Responsible person. For the quarantine charging scheme, the “responsible person” is the Secretary of the department responsible to the Minister for the Emergency Management Act 2006; that person may make quarantine debt orders (s 25B), specify amounts and family circumstances (s 25C), issue invoices (s 25E), grant exemptions and waivers (ss 25D, 25I), and delegate specified powers (s 25J).

Administrative bodies and intermediaries

• Departmental Secretaries. The Treasurer may make some waivers subject to the discretion of a departmental Secretary (s 23(1)(d)); Secretaries will need to administer any direction by the Treasurer about calculation methods or rates (s 23(2)).

• Courts, Tribunals and entities. Courts and tribunals are affected by s 20: the Attorney‑General may permit proceedings to be conducted in non‑public or electronic formats where the relevant judicial head requests it (s 20(3)). Entities that are required by other statutes to hold public meetings can be required or authorised to hold them otherwise than in person (ss 18, 20).

Private parties affected

• Quarantined persons. Individuals who are quarantined on or after 31 July 2020 may be invoiced for quarantine accommodation and services by the responsible person, subject to orders that define classes of persons liable (ss 25A, 25B, 25E). The default daily figure is $200 per person per day (s 25F(1)), with family calculations and an overall cap for family bills (s 25F(3)-(4)). Quarantined persons can apply for a certificate of exemption (s 25D) or for waivers and extensions (s 25I).

• Owners and occupiers of hotels and motels. The Act contemplates “accommodation agreements” between the Crown and hotel or motel owners under which accommodation, goods and services are provided to persons at the Crown’s request (s 25A). Those contracts will govern Crown payment to owners; the Act separately permits the Crown to invoice quarantined persons (s 25E).

• Tenants and landlords of commercial leases. Section 22 enables the Minister to declare classes of leases that may not be terminated and whose rent may not be increased within the “emergency period” as defined in the Residential Tenancy Act as amended by this Act (s 22(1)-(3)). Where such a notice applies, a termination or illegal rent increase is void (s 22(3)). This directly affects commercial landlords and tenants captured in a specified class.

• Parties required to make submissions or to attend public exhibitions. Public exhibition requirements and submission processes that would otherwise be place‑based are permitted to occur electronically under a Ministerial notice (s 19).

• Regulatory and licensing classes. The Act permits alterations to permits and appointments for Crown benefit and to postpone repeal of subordinate instruments listed in Schedule 1. Those affected include licence holders, statutory office holders, and persons subject to regulatory fees and requirements where Schedule 1 instruments are relevant (ss 14, 16, 25).

Other affected interests

• Parliament and the Subordinate Legislation Committee. Notices must be laid before each House within three sitting‑days (s 7(1)) and copies sent to the Committee within 14 days (s 7(3)). The Committee’s procedural provisions for scrutiny of delegated legislation are applied to notices (s 7(4)).

• The public and civil society. The capacity for bodies and courts to hold non‑public meetings and proceedings subject to certain conditions (ss 18(6)-(7), 20(1)) affects public access and transparency. The Act requires, where reasonably practicable, that electronic viewing be allowed for meetings held in non‑public form (s 18(7)(a)).

In short, the Act centrally affects executive decision‑makers and administrative departments as the primary actors who make and implement notices and orders; it directly captures quarantined individuals (with a new Crown debt regime), accommodation providers contracting with the Crown, tenants and landlords for rent and termination restrictions, and any person or body whose statutory procedures or obligations are capable of being temporarily modified through notice.

The Act allocates discretely specified duties and powers to ministers, administrative officers and private persons. It also creates rights (often conditional and discretionary) for quarantined persons and recipients of the Crown’s notices.

Duties and prerequisite checks before making notices

• Ministerial opinion requirement. A Minister may only issue many notices if he or she is “of the opinion” that relevant emergency circumstances exist for the notice (s 5(1)). The Act lists particular circumstances that can satisfy the test, including the presence of the disease, risk of spread, movement restrictions imposed by other instruments, reductions in available workforce for relevant activities, and supply‑chain considerations (s 5(2)).

• Economic test for financial notices. Notices under s 22 (commercial tenancy restrictions) and s 23 (Treasurer’s fee waivers) may only be issued by the Treasurer or the relevant Minister if satisfied that the economic effects of the emergency warrant the notice (s 5(3)).

• Emergency manager approval. Except for three categories of notices (a s 20 notice that relates to superior courts, s 22 or s 23 notices, and s 27 notices), notices may only be issued with the approval of the emergency manager (s 6). The emergency manager will be the State Controller during a declared state of emergency otherwise the Director of Public Health (s 4).

Procedural duties after issuance

• Gazettal and effective date. A notice only takes effect from the day it is published in the Gazette, or from a later date specified in the notice (s 8(1)). This creates a duty to ensure publication to activate the notice.

• Parliamentary laying and committee referral. The Minister must ensure a copy of a notice is laid before each House within three sitting‑days after issue (s 7(1)) and must send a copy to the Subordinate Legislation Committee within 14 days (s 7(3)). Notices are subjected to certain scrutiny and disallowance processes as if they were regulations (s 7(4)-(5)).

Powers and discretions granted

• Power to amend, revoke or re‑issue notices. Ministers have explicit power to amend or revoke notices they issue (s 11(1)), and the Act allows re‑issuance of similar notices (s 9). Amendment or revocation does not invalidate actions validly taken while the notice was in force (s 11(2)(a)-(b)).

• Electronic authorisation. The Minister may declare that acts normally requiring physical signatures, personal service or non‑electronic documents may be done electronically, subject to conditions specified in the notice (including recipient consent where required) (s 17(1)-(2)). The Minister may also permit the Gazette to be published electronically at a website (s 17(3)).

• Meetings and hearings. The Minister may authorise bodies to hold meetings in an “approved manner” (telephone/electronic/other) when requested; conditions may cover quorum and proxy nomination (ss 18(2)-(5)). The Attorney‑General may similarly authorise courts, tribunals and entities to conduct proceedings in approved non‑public forms, but only on request from relevant court or tribunal heads or entities (s 20(1)-(3)).

Quarantine scheme duties and rights

• Quarantine debt orders. The responsible person may make orders declaring classes of quarantined persons who may be required to pay specified daily amounts for days spent in quarantine (s 25B(1)). The responsible person can amend or revoke such orders (s 25B(2)).

• Invoicing and collection. The responsible person may serve an invoice on a person that specifies the quarantine debt amount and payment day (s 25E(1)). Section 25H makes the amount a debt due and payable to the Crown by the payment day, subject to exemptions and waivers.

• Exemptions, waivers and extensions. Quarantined persons may apply for certificates of exemption (s 25D(1)). The responsible person may grant exemption certificates on compassionate, medical or hardship grounds and may waive all or part of a quarantine debt or alter the payment day (s 25I(1)-(4)). A certificate can specify that, if conditions are complied with, the person is not liable to pay the amount specified in the certificate (s 25D(4)-(5)). The responsible person may act on application or on his or her own motion (s 25I(3)).

Delegations and administrative design

• Delegation. The responsible person may delegate certain powers (issuing invoices, granting exemptions and waivers) to a Deputy Commissioner or Assistant Commissioner of Police (s 25J). Ministers may delegate their powers under the Act to another Minister (s 28). The Governor may make regulations for the Act (s 29).

Rights created for affected private parties

• Quarantined persons’ procedural rights. Quarantined persons have specified procedural rights to apply for exemptions, waivers and extensions (ss 25D, 25I). An invoice must set a payment day that is after the end of a 30‑day period from service (s 25H(2)), which establishes a minimum interval within which an application may be made and considered.

• Commercial lease protections. Tenants within classes specified by Ministerial notice may have statutory protection from termination or rent increases during the declared emergency period; unlawful terminations or increases are void (s 22(2)-(3)).

Limitations and exclusions

• Time limits on notices. Notices generally expire at 12 months from their effective date unless a shorter period is specified (s 8(2)), and they are taken to be revoked 60 days after the emergency cessation day (s 8(3)). Ministers may not issue new notices (other than amending or revoking) after the emergency cessation day (s 12).

• Non‑application of s 18 Public Health Act. The Act expressly provides that s 18 of the Public Health Act 1997 does not apply to loss or damage resulting from actions under Division 2 of Part 2 of the Public Health Act in relation to the disease (s 26). This removes a statutory right or remedy under the Public Health Act for certain claims; the source text does not specify other compensation frameworks.

Overall, the Act establishes a set of executive duties to document, publish and justify temporary deviations from ordinary statutory regimes, while creating administrative rights for quarantined persons to seek relief and for courts and public bodies to operate remotely subject to request and conditions. The responsible person and departmental Secretaries are given administrative discretion and delegated authority to apply the scheme operationally.

The Act is not primarily a penal statute; it establishes administrative powers, debt recovery for quarantine accommodation, voidness of certain actions taken in contravention of Ministerial notices, and procedural obligations. It contains few express criminal penalties. Enforcement and consequential measures arise under other laws and ordinary civil processes.

Key enforceable instruments and their effects

• Quarantine invoices become Crown debts. Section 25H(1) provides that an invoice served under s 25E(1) specifying a quarantine debt amount is a debt due and payable to the Crown by the person by the payment day, subject to exemptions and waivers in ss 25D and 25I. Section 25H(2) prescribes a minimum period: the payment day must be after the end of the 30‑day period from service. The Act does not specify the precise collection mechanisms or sanctions for non‑payment within its text; unpaid Crown debts are enforceable by the Crown under ordinary debt recovery processes unless the responsible person waives or alters payment terms (s 25I).

• Voidness of prohibited lease actions. If a Ministerial notice under s 22(2) prohibits termination or rent increases for leases within a specified class during the emergency period, any termination or rent increase in contravention of that notice is “void and of no effect” (s 22(3)). The remedy is civil: a void instrument has no legal force, but the Act does not create criminal liability for a landlord who purports to terminate or increase rent. Enforcement therefore will rely on judicial or administrative recourse by affected tenants.

• Non‑application of s 18 Public Health Act. Section 26 removes the application of s 18 of the Public Health Act 1997 to loss or damage resulting from actions taken under Division 2 of Part 2 of that Act in relation to the disease. While the source text does not reproduce s 18, the effect is to prevent claims grounded in that section from being available in relation to certain public health actions; this has the practical effect of limiting remedial avenues where they would otherwise have arisen under s 18.

Missing explicit penalties

• Criminal sanctions. The Act contains no express criminal offences tied directly to most of its powers (for example no criminal penalty is imposed for failing to pay a quarantine invoice in the text provided, nor for failing to comply with modified meeting rules). Where criminal liability exists it will generally be under the laws that the notices modify (for example non‑compliance with quarantine directions given under the Emergency Management Act 2006), not under this Act. Practitioners will need to consult the parent Acts and the emergency instruments (e.g. Emergency Management Act 2006) to determine criminal exposure for non‑compliance with directions.

• Administrative sanctions and review. The Act provides procedural constraints (Gazettal, parliamentary laying, committee scrutiny) and allows affected persons to seek waivers, exemptions and extensions (ss 25D, 25I). The absence of express appeal mechanisms in Part 6A for decisions of the responsible person is notable in the text: waivers and changes are discretionary, and delegation to senior police officers is authorised (s 25J), but the Act does not set out an internal review procedure or judicial review bar. Ordinary administrative law remedies (e.g. reviewability by the courts) are not altered in express terms by the provisions reproduced, though s 11(2) preserves the validity of actions taken while a notice was in force.

Enforcement interaction with other laws

• Where the Act amends or suspends the operation of other statutes by notice, enforcement for contraventions of the underlying statutes will depend on whether the Minister’s notice has modified or suspended the relevant statutory obligation. For example, s 14 permits the Minister to amend or revoke permit provisions despite any other instrument; if a permit provision is suspended by notice, enforcement of the original permit condition will be inapposite for the period specified.

• The Act applies scrutiny and legal formalities that treat notices as if they were regulations for purposes of certain Acts (s 7(4)-(5)). That ensures notices, while immediate on Gazettal, are subject to parliamentary and committee review and disallowance mechanisms that operate against subordinate legislation, thereby creating a political and legal check that can have enforcement‑adjacent effects (political scrutiny leading to revocation, for example).

In short, the Act creates enforceable civil obligations (Crown debts for quarantine invoices and the civil nullity of disallowed lease terminations/rent increases) and empowers authorities to alter statutory obligations. Criminal enforcement for non‑compliance with public health directives and quarantine directions is not expressly created in this Act; such criminal provisions, if any, exist in the Emergency Management Act 2006 or other parent legislation. The Act’s principal enforcement leverage is administrative discretion coupled with ordinary Crown debt recovery and civil remedies.

The Act functions as an enabling, overriding and time‑limited instrument that deliberately operates by modifying or suspending the operation of other Acts and subordinate instruments through Ministerial notices, Treasurer directions, orders by the responsible person, and by giving specific effect to some subordinate instruments listed in Schedule 1.

Direct override powers

• “Despite” formulation. Multiple provisions operate “despite” the provisions of other legislative instruments. Examples include the Minister’s power to amend or revoke permits regardless of other instruments (s 14), authorisation for electronic actions “despite the provision of any relevant legislative instrument” (s 17), and the authorisation for meetings and public exhibitions to be held electronically despite statutory requirements for place or manner (ss 18-19). This creates a legislative hierarchy in practice for the period notices are in force: the Minister’s notice can temporarily displace the statutory requirement.

• Inconsistency and permit conditions. Where a notice under s 21 alters shop trading hours in a way inconsistent with permit conditions under a planning permit, s 21(2) provides that the permit condition does not have effect to the extent of the inconsistency. This is a direct statutory override of permit conditions for the specified day(s).

Interaction with procedural and scrutiny laws

• Treating notices as regulations. Section 7 applies parts of the Subordinate Legislation Committee Act 1969 and the Acts Interpretation Act 1931 to notices as if the notices were regulations; this attaches existing parliamentary scrutiny and procedural mechanisms for delegated legislation to Ministerial notices under this Act. Practically, that subjects the notices to disallowance and tabling rules and to the Committee’s processes.

Relationship with the Emergency Management Act 2006 and Public Health Act 1997

• Emergency manager and quarantine directions. The emergency manager role is drawn from the Emergency Management Act 2006 (s 4 definition). The quarantine direction that triggers the Part 6A charging power is a direction given by an authorised officer under the Emergency Management Act 2006 in accordance with an authorisation under s 40 of that Act (s 25A definition). Therefore, enforcement and obligations under the Emergency Management Act are a predicate for the charging and invoicing powers.

• Non‑application of s 18 Public Health Act 1997. Section 26 expressly prevents s 18 of the Public Health Act 1997 from applying to any loss or damage suffered as a result of anything done under Division 2 of Part 2 of the Public Health Act in relation to the disease. This is a specific carve‑out that removes a remedial provision contained in the Public Health Act from operating in relation to COVID‑19 public health actions.

Cross‑references and consequential amendments

• Residential Tenancy and other Acts. Section 22 references an “emergency period” with the same meaning as in the Residential Tenancy Act 1997 as amended by this Act, and Schedule 2 lists consequential amendments to the Emergency Management Act 2006 and the Residential Tenancy Act 1997 (Schedule 2, s 30). The Act therefore envisages coordinated modifications across multiple statutes.

• Schedule 1 subordinate instruments. Section 25 postpones the repeal of specified regulations and rules listed in Schedule 1. Those regulations include a wide range of administrative and fee instruments (for example Land Tax Regulations 2010, Taxation Administration Regulations 2010, Driver Licensing Regulations 2010, and others). The postponement ensures those instruments remain in force beyond their scheduled sunsetting date, preserving regulatory continuity where otherwise they would have been repealed under the Subordinate Legislation Act 1992 (s 25(2)).

Limits and non‑derogation

• Preservation of validity of prior actions. Section 11(2) provides that amendment or revocation of a notice does not render invalid any action taken under a provision of an Act while the notice was in force, nor does it render invalid subsequent actions taken in reliance on the initial action. That preserves legal certainty for acts undertaken in good faith while the notice was operative.

• Time limits and cessation. Notices operate only while in force and are time‑limited under s 8; after the emergency cessation day (declared under s 27 following the Director of Public Health’s advice), notices are taken to be revoked after 60 days (s 8(3)) and new notices (other than amending or revoking) may not be issued after the emergency cessation day (s 12). This provides a statutory sunset and prevents indefinite override of other laws beyond the emergency window.

Implementation dependencies and administrative coordination

• Delegated rule‑making and orders. The Act relies on orders by the responsible person and on the Governor’s regulation power (s 29), which means substantive administration will depend on secondary instruments that specify classes of persons, amounts, prescribed Acts or classes of permits. The definition of “permit” includes classes that may be prescribed or arise under a “relevant licensing Act” (s 4), creating a dependency on delegated instruments and regulations for operational detail.

In sum, the Act is designed to be invasive of ordinary statutory operation during an emergency but to do so in a time‑limited, notice‑driven and procedurally supervised way. It creates direct interactions with the Emergency Management Act 2006 and Public Health Act 1997, pauses scheduled repeals of specified subordinate instruments, and makes subordinate or delegated instruments central to operationalising many parts of the Act.

The Act as provided contains express internal amendment annotations identifying changes made during 2020. The source text includes bracketed amendment notes tied to particular sections and records the insertion of Part 6A late in 2020. The explicit amendment record in the source is limited but clear for certain sections.

Noted amendments and inserts

• Section 4 amendments. Section 4 (Interpretation) carries amendment notes showing changes by No. 12 of 2020, s 18, applied 6 May 2020. The amendments inserted the definition and scope of “permit” and the definition of “relevant licensing Act” (s 4 notes).

• Section 13 subsection (1) amendment. There is a bracketed note that s 13(1) was amended by No. 12 of 2020, s 19 (applied 6 May 2020) to give the Minister power to declare altered periods for actions under relevant legislative instruments; s 13(2) uses an express six‑month cap for extending prosecutorial limitation periods.

• Inserted Part 6A. Sections 25A-25J, forming Part 6A “Charging For Quarantine Accommodation”, are marked as inserted by No. 17 of 2020, s 4, applied 3 September 2020 (the source shows [Section 25A Inserted by No. 17 of 2020, s. 4, Applied:03 Sep 2020] and similar for subsequent sections). The insertion introduces the quarantine debt regime and associated definitions, order powers, invoicing, waiver/exemption powers and delegation.

• Schedule 1 amendment note. Schedule 1 carries an amendment note indicating a change by No. 17 of 1996 applied 27 March 2020, specifically in relation to the Fair Trading (Code of Practice for Retail Tenancies) Regulations 1998 listing (Schedule 1(4)).

Other structural points noted in the text

• Commencement. Section 2 states that the Act commences on the day of Royal Assent. The source text includes this basic commencement provision.

• Administration assignment. Until administrative arrangements are otherwise specified under the Administrative Arrangements Act 1990, administration of the Act is assigned to the Premier and to the Department of Premier and Cabinet (s 31). That is a temporary administrative assignment clause.

• Consequential amendments identified. Schedule 2 identifies consequential amendments to the Emergency Management Act 2006 and the Residential Tenancy Act 1997 (Schedule 2, s 30), signalling that the Act had intended consequential textual or operational amendments to those parent Acts.

What the source does not show

• The Act text reproduced does not include a consolidated chronicle beyond the 2020 amendments identified by bracketed notes. No other amendment years, explanatory memoranda or second reading speeches are present in the supplied text. The insertion of Part 6A and the early May 2020 amendments are the principal documentary amendment history items the source shows.

For practitioners, the annotated notes in the text flag where substantive policy changes were introduced in 2020 , especially the quarantine charging regime added on 3 September 2020 , and where the interpretation/definitions in s 4 were broadened in May 2020. Any further amendments or later rescissions are not present in the provided material and would require checking the consolidated legislation history published by the Parliamentary Counsel or government legislative repositories.

The statutory text provided contains no judicial decisions, case citations, or litigation history. The Act itself does not name any cases nor reference any judicial determinations about its provisions. There is therefore no litigation history contained in the source material to summarise.

Where litigation might arise (based on the Act’s mechanisms)

• Quarantine debt disputes. Disputes could be expected in practice over the validity of quarantine debt orders, the correctness of invoices, the adequacy or fairness of the family debt calculation and caps, the proper application of exemptions or waivers, or over delegation (s 25J). The Act provides administrative avenues (applications for waivers and exemptions under s 25I and certificates under s 25D) but does not set out a statutory appeal or review procedure in the quoted text; affected persons would therefore likely seek judicial review of administrative decisions or civil remedies in ordinary courts if challenges were necessary.

• Notices modifying statutory rights and procedural access. Decisions to hold hearings or meetings behind closed doors or to permit non‑public electronic proceedings under s 20 or to alter public exhibition requirements under s 19 could give rise to judicial review or statutory interpretation disputes, in particular where persons claim breach of procedural fairness or statutory requirements that they assert cannot be lawfully displaced by notice. The Act does, however, include broad “despite” language and subjects notices to parliamentary scrutiny.

• Compensation and liability. Section 26 removes s 18 of the Public Health Act 1997 from applying in certain contexts, thereby narrowing potential compensation claims under that section; any litigation about whether an action falls within the excluded category or whether other compensation avenues remain would require judicial clarification.

Absence of cases in source

• Because no judicial decisions are recorded in the statutory text supplied, practitioners will need to search case law databases and later legislative materials to identify if courts have ruled on questions arising from this Act. The provided text does not permit identification of actual litigation outcomes, challenge patterns, or judicial interpretation.

In short, while the Act’s content creates several friction points likely to generate litigation in practice, the supplied statutory text contains no litigation history or judicial authorities to cite. Users seeking case law will need to consult court databases for decisions interpreting the Act or disputes arising under its quarantine billing, waiver, and notice schemes.

This Act creates many powerful, temporary and administratively driven modifications to ordinary legal obligations. Several practical pitfalls and operational ambiguities in the text merit attention.

Broad discretion and “opinion” standard

• High discretionary threshold couched as “opinion”. Ministers may only issue most notices if they are “of the opinion” that relevant emergency circumstances exist (s 5(1)). That phrasing confers executive discretion rather than an objective statutory test. Practitioners should note that the Act does not prescribe evidentiary standards for forming the requisite opinion; operational decisions will therefore be sensitive to administrative record‑keeping, justification and contemporaneous documentation.

• Wide definition of ‘relevant emergency circumstances’. The list in s 5(2) covers disease presence, contraction risk, movement restrictions, workforce reductions, and desirability of ensuring supply of goods or services. This breadth allows many interventions to be characterised as necessary: for example altering permit conditions to maintain supply chains (s 5(2)(e)). That breadth increases legal uncertainty about what the notice powers may encompass.

Emergency manager approval and delegation traps

• Emergency manager approval centralises a check but limits ministers’ unilateral action (s 6). However s 6 excludes some notices from emergency manager approval (notably s 22, s 23 and s 27 notices), so ministers and the Treasurer retain unilateral scope in financial and tenancy domains. Understanding which notices require approval is necessary to avoid procedural invalidity.

• Delegation of responsible person powers includes police executives. Section 25J permits delegation of certain powers under the quarantine scheme to Deputy or Assistant Commissioners of Police; practitioners should be alert that operational decisions about waivers or invoicing may be made within police command structures, which affects internal accountability pathways.

Notice effect, timing and parliamentary scrutiny

• Immediate effect upon Gazette publication. Notices take effect from Gazettal (s 8(1)) and must be laid before Parliament within three sitting‑days (s 7(1)). That means practical changes can occur before parliamentary review. Entities should monitor the Gazette closely because retroactive challenges are limited by s 11(2), which preserves the validity of actions taken while a notice was in force.

• Short maximum duration per notice but re‑issuance permitted. Most notices expire after up to 12 months (s 8(2)), but s 9 permits re‑issue of similar notices. The ability to “re‑issue” can produce rolling extensions by successive notices rather than a single continuous instrument, affecting long‑term planning for businesses and individuals.

Quarantine charging specifics: timing and family calculations

• Payment timing floor and 30‑day window. An invoice’s payment day must be after the end of a 30‑day period from service (s 25H(2)). However, invoices are debts that become due on the payment day (s 25H(1)). Practitioners should note that the minimum 30 days provides a window for waiver or extension applications, but the responsible person can still impose a default payment date after that 30‑day minimum; operationally this may affect cash flow or ability to challenge.

• Family debt calculation and caps. The family debt mechanism (s 25F(3)-(4)) aggregates per‑person and per‑family member amounts and imposes a $4,800 default cap (or another amount specified by order). Administratively, orders under s 25C determine “relevant family circumstances” and which family members may be grouped. That introduces a point of potential dispute,how “family” is characterised by orders, and whether persons should be charged individually or as a family unit (s 25C(2)). Section 25E(3) prevents multiple invoices for the same day in certain family circumstances, but practitioners should check the operative orders to see when family aggregation applies.

No express appeal mechanism for administrative decisions

• Waiver and exemption decisions are discretionary and the Act does not set out a statutory internal review or merits appeal process in the text. While administrative decisions are generally subject to judicial review, there is no expedited internal appeal process prescribed. Affected persons may need to apply for waivers quickly and, if refused, resort to judicial review or negotiate with the responsible person.

Non‑application of Public Health Act compensation

• Section 26 removes s 18 of the Public Health Act 1997 for actions done under Division 2 of Part 2 in relation to the disease. Practitioners should not assume a right to compensation under s 18 for loss or damage resulting from certain public health actions. The text does not provide a replacement compensation mechanism.

Ambiguity in “permit” and “relevant licensing Act”

• “Permit” includes classes prescribed or issued under “relevant licensing Acts” and the definitions in s 4 were amended in May 2020 to incorporate a non‑exhaustive list of relevant licensing Acts. Where permits are affected, practitioners should check the list of Acts and any subsequent regulations to determine whether a particular licence or permit is captured.

Scope limits and sunset confusion

• Emergency cessation timeline. The Director of Public Health must notify the Minister when emergency circumstances no longer exist (s 27(1)), and the Minister must declare an emergency cessation day within 90 days of that notification (s 27(2)). Notices are taken to be revoked 60 days after that day (s 8(3)). Planning for unwind requires tracking these timings and managing expectations about when notices will stop applying.

Miscellaneous operational risks

• Postponement of scheduled repeals in Schedule 1 may keep instruments in force longer than anticipated (s 25). Organisations planning for regulatory change must check Schedule 1 and the postponed dates.

• Treating notices as regulations subjects them to Subordinate Legislation Committee processes, but it does not convert notices into long‑term law: their temporary and notice‑driven character remains. Practitioners should keep documentary evidence of compliance and of the exact notice text in force at any relevant time, because revocations or amendments will not retroactively invalidate actions taken under a then‑valid notice (s 11(2)(a)).

In practice, the combination of broad discretion, delegation, expedited Gazettal effect, limited internal appeal procedures and specific debt recovery mechanisms for quarantine accommodation creates multiple potential operational and legal pitfalls. Careful monitoring of the Gazette, the Subordinate Legislation Committee outputs, the emergency manager’s approvals, and any orders under Part 6A will be essential.

Compliance under this Act splits into two categories: (1) responsibilities for public authorities, ministers and administrators who must follow procedural prerequisites when exercising powers; and (2) obligations and practical compliance steps for private parties affected by notices and the quarantine debt regime.

For ministers, emergency managers and departments

• Maintain documentary justification for “opinion” decisions. Ministers should prepare and retain contemporaneous records supporting the opinion that “relevant emergency circumstances” exist under s 5, including factual bases for each element relied on (presence of disease, risk of spread, movement restrictions, workforce reductions, supply constraints). The Act relies on an opinion standard; good administrative practice is to record the basis for the opinion to reduce legal challenge risk.

• Obtain emergency manager approval where required. Where a notice falls within the class that requires emergency manager approval under s 6, secure written approval before issuing, bearing in mind s 6 excludes s 22, s 23 and s 27 notices. Ensure the emergency manager’s approval is placed on file.

• Ensure Gazettal and Parliamentarian laying rules are satisfied. Publish the notice in the Gazette to bring it into effect (s 8(1)), lay a copy before each House within three sitting‑days (s 7(1)), and send a copy to the Subordinate Legislation Committee within 14 days (s 7(3)). Failure to meet these time lines risks non‑compliance with procedural prerequisites and intensifies scrutiny.

• Use s 11 safeguards when amending or revoking notices. When amending or revoking notices, document the continuity rationale and rely on s 11(2) that prior actions remain valid; this will be important for administrators and regulated parties who acted while the notice was in force.

• Prepare internal administrative systems for invoices and waivers under Part 6A. For departments administering quarantine debts, create processes for (a) issuing quarantine debt orders under s 25B, (b) serving invoices (s 25E), (c) receiving and determining waiver and extension applications (s 25I), (d) granting exemption certificates (s 25D), and (e) logging delegation decisions under s 25J. Ensure staff are briefed on timelines including the mandated minimum 30 days before the payment day (s 25H(2)).

For the responsible person (departmental Secretary)

• Formalise order‑making criteria and family definitions. When making orders under s 25C about family circumstances and amounts, define “member of a family” and “relevant family circumstances” clearly and publish those orders so recipients and accommodation providers know when family aggregation applies. Use s 25E(3) to avoid duplicate invoices for the same day in family scenarios.

• Establish a delegation and decision trail where powers are delegated to police executives. Document delegations under s 25J in writing, publish them if appropriate, and provide guidance for delegated officers to ensure consistent waiver and invoice decisions.

For entities and bodies that need to alter meeting procedures

• Make formal requests where required. Section 18(5) requires that a Minister may issue a notice in relation to a body of persons only if one or more members or a nominated person have requested it. Bodies seeking authority to meet electronically should ensure a proper written request is made and keep copies.

• Comply with approved manner and conditions for meetings. If a notice allows remote meetings, follow the conditions specified in the notice (s 18(3)-(4)), including quorum rules and proxy nomination requirements. Where meetings are permitted not to be public, include electronic viewing arrangements “if reasonably practicable” (s 18(7)(a)).

For courts, tribunals and entities

• Request Attorney‑General notices where necessary. Heads of courts and tribunals must request s 20 notices for their proceedings to be conducted in the approved non‑public manner. Ensure that such requests are documented and that the approved manner is implemented in accordance with directions from the Chief Justice, Chief Magistrate or Tribunal head (s 20(2)-(3)).

For quarantined persons and accommodation providers

• Quarantined persons: apply early for exemptions and waivers. Persons who expect to be quarantined should consider applying for a certificate of exemption under s 25D(1) if they face compassionate, medical or financial hardship; certificates may be granted where appropriate (s 25D(3)). They may also apply for waiver or extension under s 25I(1) if an invoice is served. Timeliness is crucial given the invoice payment timing constraints (s 25H(2)).

• Accommodation providers: secure clear accommodation agreements with the Crown. Hotels and motels contracting to provide Crown‑requested quarantine accommodation should record clear terms in their accommodation agreements (s 25A definition) addressing payment, responsibility for Crown charges, liability limits, and service standards. While the Crown may invoice quarantined persons, providers need contracts that ensure prompt payment by the Crown rather than relying on recovery from quarantined persons.

For landlords and tenants

• Monitor for s 22 notices that affect lease termination and rent increases. Tenants and landlords should track notices published under s 22 to determine whether a particular lease falls within the protected class. Where a notice applies, terminations or rent increases in contravention are void (s 22(3)); affected tenants should preserve evidence of the lease and of any attempted termination or rent increase for enforcement.

For businesses and regulatory licence holders

• Check whether permits or licences have been varied. Because ministers may amend permit provisions by notice (s 14) and the Act affords wide “despite” powers, businesses should check the Gazette and the relevant departmental notices to confirm whether their permit conditions or statutory obligations have been temporarily suspended or altered. Where regulations listed in Schedule 1 have their repeal postponed (s 25), continue to comply with those instruments.

General operational practice

• Maintain notice‑by‑notice compliance registers. Because notices may vary in scope and duration and may be re‑issued (s 9), organisations should maintain a register of current notices, their Gazettal dates, effective periods, approval records, and links to the underlying statutory provisions they alter.

• Plan for unwind and post‑cessation. The Director of Public Health must notify when emergency circumstances no longer exist and the Minister must declare an emergency cessation day within 90 days (s 27). Notices are taken to be revoked 60 days after that day (s 8(3)). Organisations should model both the active period and the 60‑day wind‑down period to manage staffing, contractual and regulatory changes.

• Use statutory procedural protections to preserve actions taken under notices. When relying on actions taken while a notice was in force, document the notice relied upon and the date of Gazettal because s 11(2) preserves the validity of such actions even after amendment or revocation.

In short, compliance requires proactive monitoring of Gazettal, clear administrative processes for issuing and responding to quarantine invoices and waiver/exemption applications, careful record‑keeping to demonstrate satisfaction of opinion and approval prerequisites, and contractual clarity between accommodation providers and the Crown. Private parties should act promptly to apply for waivers or exemptions where invoices are served, and public authorities should document approvals, delegations and the factual basis for decisions to withstand potential review.
