Public Health Act 2010

The Act casts a wide net. At the highest level, the Minister and Secretary exercise overarching powers under ss 7–9 and 16. The Chief Health Officer has specific responsibilities for boil-water advice (s 21), public warnings (s 12A) and certain notifications. Public health officers coordinate activities within geographic areas (s 122) and may exercise authorised-officer powers (s 124). Authorised officers, appointed by the Secretary or local government authorities (s 126), perform the bulk of investigative and enforcement functions (Part 8).

Local government authorities are given direct statutory responsibilities for environmental health compliance in their areas (s 4) and may issue improvement notices and prohibition orders (s 45). They must appoint their own authorised officers and ensure those officers perform their functions.

Suppliers of drinking water (defined expansively in s 5(1) to include Sydney Water, Hunter Water, water supply authorities, licensed operators and certain commercial suppliers) are subject to strict duties under Division 1 of Part 3. They must maintain quality-assurance programs (s 25), comply with testing and information directions (ss 18–19), and issue public alerts when required (s 22).

Occupiers of premises on which regulated systems, public swimming pools, spa pools or skin-penetration procedures are carried out face ongoing compliance obligations (ss 28–30, 35–36, 38). They must notify installation of certain systems (s 31), display prohibition orders (s 37), and may be subject to improvement notices or prohibition orders (ss 41–45). Duly qualified persons engaged to install, operate or maintain regulated systems bear personal liability if prescribed requirements are not met (ss 28(3)–(4), 29(3)–(4), 30(3)–(4)).

Medical practitioners, pathology laboratories and health practitioners are required to notify scheduled and notifiable diseases (ss 54–55, 82–83), provide information to patients with sexually transmissible infections (s 78), and may be directed to supply further data to the Secretary (ss 54(3A), 55(4)). Principals of schools and child-care facilities must enforce immunisation requirements (ss 86–87) and exclude at-risk children during outbreaks (s 88).

Persons who have, or are suspected of having, a Category 4 or 5 condition or a contact-order condition may be made subject to public health orders that restrict their liberty, require treatment or authorise detention (s 62). Individuals who know they have a sexually transmissible notifiable disease must take reasonable precautions (s 79(1)). Persons operating reproductive health clinics and members of the public near those clinics are affected by the safe-access-zone prohibitions in Part 6A.

De-registered health practitioners, persons subject to prohibition orders, and relevant health organisations must disclose their status before providing services and must not advertise without disclosure (ss 102–103). Corporations that breach the Act face multiplied penalties (e.g. s 10(b), s 15(b)). Finally, the Act binds the Crown (s 6) but the Crown is not liable to prosecution.

Duties fall into three broad categories: positive obligations to notify or maintain standards, negative obligations to refrain from conduct that endangers health, and procedural obligations to comply with official directions.

Positive duties include the obligation on drinking-water suppliers to supply only fit water (s 15), to maintain quality-assurance programs and provide copies to the Secretary (s 25), on occupiers to ensure regulated systems are installed, operated and maintained in accordance with prescribed requirements (ss 28–30), on pool operators to disinfect and clean (s 36), on skin-penetration premises to comply with regulatory standards (s 38), on medical practitioners and laboratories to notify scheduled conditions (ss 54–55), on hospital CEOs to notify notifiable diseases (s 83), and on principals to sight immunisation certificates (ss 86–87).

Negative duties prohibit supplying unfit water (s 15), failing to take reasonable precautions against spreading Category 2–5 conditions in public places (s 52), failing to take precautions against spreading sexually transmissible scheduled conditions (s 79(1)), interfering with access to reproductive health clinics or making distressing communications in safe access zones (ss 98C–98D), and capturing or distributing visual data in those zones without consent (s 98E).

Procedural duties require compliance with Ministerial directions (s 10), Secretary’s testing and information directions (ss 20, 23), improvement notices (s 43), prohibition orders (s 47), public health orders (s 70), and requests for name and address (s 112). Authorised officers must be given answers and documents when directed (ss 110–111).

Rights are primarily procedural. Persons subject to public health orders based on Category 5 conditions or contact-order conditions receive an expedited NCAT review (s 64). Occupiers may request re-inspection after a prohibition order and are taken to have received a clearance certificate if inspection does not occur within two working days (s 46). Administrative review by NCAT is available for certain Ministerial actions (s 7(7)), refusal of clearance certificates (s 48), compensation decisions (s 49), and public health orders based on Category 4 conditions (s 66). A person who suffers damage from disinfection or destruction of a noxious article is entitled to reasonable compensation unless the condition was their own fault (s 12(4)). Good-faith providers of drinking-water advice are protected from liability (s 24), as are issuers of public warnings (s 12B) and persons exercising functions under the Act (s 133). Patients subject to public health orders have a right to inspect their medical records (s 69). The Act expressly preserves the paramountcy of public health while requiring authorised medical practitioners to consider the principle that restrictions on liberty should be the least restrictive effective measure (s 62(6)(a)).

The Act employs a graduated enforcement pyramid. At the base are improvement notices (s 42) that give 72 hours (or longer) to remedy non-compliance with enforceable requirements for regulated systems, public pools or skin-penetration premises. Failure to comply allows the Secretary or local authority to undertake the work and recover costs (s 44).

The next tier is the prohibition order (s 45), which may be issued if an improvement notice is ignored or where urgent action is needed to prevent serious risk. Prohibition orders close regulated systems, pools or skin-penetration premises until a clearance certificate is issued. Contravention carries up to 500 penalty units or 12 months imprisonment (individual) or 2,500 penalty units (corporation) for regulated systems, and 200 penalty units or 12 months (individual) or 1,000 penalty units (corporation) for pools or skin-penetration premises, plus daily continuing penalties (s 47).

For drinking-water offences the penalties are higher: 2,500 penalty units or 12 months (individual) or 10,000 penalty units (corporation) for supplying unfit water (s 15), with matching continuing penalties for breach of Ministerial directions (s 17). Ministerial directions under ss 7–9 carry 100 penalty units or 6 months (individual) or 500 penalty units (corporation) plus daily penalties (s 10).

Public health orders attract 100 penalty units or 6 months imprisonment (s 70). Safe-access-zone offences start at 50 penalty units or 6 months and double for subsequent offences (ss 98C–98E). Failure to notify scheduled conditions carries 50 penalty units (ss 54–55). Obstruction or assault of authorised officers carries 100 penalty units or 6 months (s 116).

Enforcement tools include entry and inspection powers (s 108), search warrants (s 109), power to require answers and documents (ss 110–111), and name-and-address demands (s 112). Penalty notices may be issued for prescribed offences (s 118). Proceedings are generally summary but the offence of providing a health service in contravention of a prohibition order (s 102(3)) may be prosecuted on indictment (s 117(3A)). Corporate officers are personally liable if they knowingly authorise or permit breaches (s 119). Continuing offences attract daily penalties (s 120).

The Crown is bound but not liable to prosecution (s 6(2)). Authorised officers and public health officers are protected from personal liability for good-faith actions (s 133).

The Act is expressly linked to a web of related statutes. Definitions in s 5 incorporate terms from the Local Government Act 1993 (councils, areas), Health Services Act 1997 (public health organisations, NSW Health Service), Health Care Complaints Act 1993 (health practitioners, relevant health organisations), Health Practitioner Regulation National Law (NSW) (registered health practitioners), Mental Health Act 2007, Private Health Facilities Act 2007, Strata Schemes Management Act 2015, Water Management Act 2000, Water Industry Competition Act 2006, Aged Care Act 1997 (Cth), Crown Land Management Act 2016, Government Sector Employment Act 2013, Interpretation Act 1987, Administrative Decisions Review Act 1997, State Emergency and Rescue Management Act 1989, Privacy and Personal Information Protection Act 1998, Health Records and Information Privacy Act 2002, Births, Deaths and Marriages Registration Act 1995, Law Enforcement (Powers and Responsibilities) Act 2002, Fines Act 1996, Children (Education and Care Services) National Law (NSW), Therapeutic Goods Act 1989 (Cth) and Mandatory Disease Testing Act 2021.

Section 7(6) provides that Ministerial orders have no effect in areas subject to a state of emergency under the State Emergency and Rescue Management Act 1989. Section 8(6) deems action taken under that section to have been taken under the 1989 Act, attracting its obstruction and immunity provisions. Public health orders interact with the Mental Health Act 2007 and guardianship legislation through the least-restrictive principle in s 62(6)(a).

Privacy legislation is disapplied for public warning statements (s 12A(3)) but continues to limit use of health information (note to s 56). The Act prevails over certain summary-offence and law-enforcement provisions in safe-access-zone matters (s 98F(2)).

Notification obligations under Part 4 operate alongside, and in some cases defer to, notifiable-disease obligations under Part 5 (s 54(4)). The Pap Test Register established under the repealed 1991 Act continues under this Act (Sch 5 cl 5). Regulation-making powers allow adoption of external publications (s 134(3)) and exemption from certain cremation and burial requirements (s 134(2A)).

Liability provisions interact with the Civil Liability Act 2002 and common-law defences. Compensation for destruction of noxious articles is paid from parliamentary appropriation (s 12(5)). NCAT reviews are conducted under the Administrative Decisions Review Act 1997 and Civil and Administrative Tribunal Act 2013.

The Act has been amended on more than a dozen occasions since 2010, reflecting evolving public-health threats and policy priorities.

The Public Health Amendment (Review) Act 2017 (No 43) was the most comprehensive overhaul. It inserted s 3(f) (monitoring diseases), amended local-government responsibilities (s 4), expanded the definition of supplier of drinking water and occupier (s 5), introduced quality-assurance compliance and provision obligations (s 25(1A)–(1B)), updated the definition of public swimming pool (s 34), added Category 5 conditions and contact-order conditions to the scheduled-medical-conditions regime (s 51, Sch 1A), clarified notification duties (ss 54–56), expanded public-health-order grounds to include persons exposed to contact-order conditions (s 62(1)(b)), shortened the automatic expiry of Category 5 and contact-order orders to three business days unless confirmed (s 63(2)), and made consequential changes to NCAT review provisions. These changes implemented recommendations of a statutory review and strengthened management of blood-borne viruses and emerging infections.

The Public Health Amendment (Immunisation) Act 2013 and the 2017 amendments tightened childcare enrolment requirements (s 87), replacing the previous conscientious-objection exemption with a strict medical-contraindication-only regime. This was a deliberate policy response to declining herd immunity and measles outbreaks.

The Reproductive Health (Access to Terminations) Act 2018 inserted Part 6A to create safe access zones, responding to evidence of harassment outside clinics. The Public Health Amendment (Safe Access to Reproductive Health Clinics) Act 2018 added the 150-metre buffer, communication and visual-data offences, and related immunities.

In response to the COVID-19 pandemic, temporary provisions were inserted in 2020–2021 (ss 63(2A)–(2C), 71A, amendments to ss 61, 112 and 118) to facilitate rapid public-health orders, contact tracing and penalty-notice regimes. Most of these provisions have since been repealed or are scheduled for repeal (s 135), but they illustrate the Act’s adaptability through regulation and amendment.

The Public Health Amendment (Vaccine Preventable Diseases) Act 2023 and 2024 updates to Schedules 1–3 added or refined conditions such as respiratory syncytial virus, mpox and carbapenemase-producing Enterobacterales, reflecting laboratory and epidemiological developments. The Health Legislation (Miscellaneous) Amendment Act (No 2) 2022 updated identification-card requirements for authorised officers (new s 127A) and made minor procedural adjustments.

These changes demonstrate a legislative trend toward greater specificity in disease lists, stronger immunisation and clinic-access protections, expanded public-communication powers, and procedural streamlining for emergency response.

Because many of the Act’s powers are exercised administratively and reviewed by NCAT rather than the courts, reported case law is relatively sparse. Nevertheless, several themes emerge from Tribunal and judicial decisions.

Public-health-order cases have tested the evidentiary threshold for “reasonable grounds” under s 62. NCAT has emphasised that the authorised medical practitioner must hold an actual belief based on objective material and must apply the least-restrictive-principle in s 62(6)(a). In several unreported decisions involving Category 5 conditions (primarily HIV and hepatitis C), the Tribunal has varied orders to substitute supervised treatment for detention where the person demonstrated insight and compliance.

Safe-access-zone prosecutions under ss 98C–98E have generated controversy. Civil-liberties groups argued that the 150-metre buffer and communication restrictions infringe implied freedom of political communication under the Commonwealth Constitution. To date, no superior-court decision has invalidated the provisions, but lower-court proceedings have turned on whether particular conduct occurred inside the zone and whether the communication was “reasonably likely to cause distress or anxiety”. The exemption for Parliament House and electoral activity (s 98F(1)(b)–(c)) has been criticised as inconsistent.

Drinking-water prosecutions are rare but carry heavy penalties. In one contested matter concerning a private supplier, the court accepted a due-diligence defence under the general criminal-law provisions where the supplier had relied on contemporaneous test results later shown to be erroneous.

Legionella enforcement has produced disputes about the meaning of “prescribed maintenance requirements”. NCAT has held that an improvement notice must identify with precision which regulatory or Secretary-determined requirement has been breached.

The interaction between the Act and the Mandatory Disease Testing Act 2021 has been the subject of administrative review applications concerning disclosure of Category 5 information (s 56(4)(f1)). The Secretary’s power to direct disclosure for mandatory testing has been upheld where public-health risk is demonstrated.

Controversies have also arisen over the breadth of Ministerial powers under s 7 during the COVID-19 pandemic. Although most directions were made under specific public-health orders rather than the parent Act, the 90-day limit and NCAT-review rights in s 7(7) were cited in parliamentary debates as important safeguards. The temporary provisions in s 135 attracted criticism for extending the life of certain emergency measures beyond the original pandemic response.

Overall, the case law shows NCAT adopting a merits-based, public-health-focused approach that gives weight to expert evidence while insisting on procedural fairness and proportionality.

Most practitioners are surprised by three features. First, the definition of “occupier” in s 5(1) is not the ordinary common-law meaning; for air-handling and cooling-water systems in strata schemes it is the owners corporation, not the lot owner. This shifts primary liability to the body corporate and can catch strata managers unaware.

Second, the automatic three-business-day sunset for Category 5 and contact-order public health orders (s 63(2)) is frequently overlooked. If the Secretary intends to maintain the order, an NCAT application must be filed and served before the three days expire; otherwise the order lapses even if the risk remains. The clock starts on personal service, not the making of the order.

Third, the safe-access-zone offences in Part 6A apply to still or moving images capable of real-time transmission even if not actually transmitted (s 98E(4)). Security-camera operators at adjacent premises are exempt only if the footage is used solely for security and provided only to the clinic operator or police. Recording for journalistic or protest purposes inside the zone is therefore high-risk.

Another trap is the continuing daily penalty for breach of prohibition orders (s 47). Each day the system, pool or premises remains open after the order is served counts as a fresh offence, rapidly escalating exposure. Because prohibition orders can be issued without a prior improvement notice where urgency exists (s 45(1)(b)), operators can find themselves closed without prior warning.

The evidentiary certificate provision in s 14 (drinking-water directions) and the prima-facie evidentiary effect of Ministerial orders published in the Gazette (s 7(4)) are often under-utilised by prosecutors. Conversely, defence practitioners sometimes miss the defence in s 52(2) that the defendant was unaware of the medical condition at the relevant time.

Finally, the regulation-making power in s 134(3) to adopt external standards “as in force from time to time” means that changes to Australian Standards or WHO classifications can automatically alter legal obligations without further parliamentary scrutiny. Compliance programs must therefore track those external documents.

Compliance begins with a thorough gap analysis against the enforceable requirements in Divisions 2–4 of Part 3 and the notification obligations in Parts 4 and 5. Water suppliers should maintain an auditable quality-assurance program that meets the minimum content prescribed by regulation (s 25(2)) and ensure that raw, in-process and finished-water testing regimes are documented and reported to the Secretary on request (ss 18–19). Legionella risk-management plans for regulated systems must address the prescribed installation, operating and maintenance requirements; records must demonstrate that only “duly qualified” persons perform the work. Annual notification of cooling and warm-water systems (s 31) and prompt reporting of Legionnaires’ disease clusters are mandatory.

Pool and spa operators must implement a water-quality monitoring program that achieves the disinfection outcomes in s 36(1) and keep surrounds clean. A current copy of the prohibition-order register should be displayed at entrances. Skin-penetration premises require written infection-control protocols, sterilisation logs, and pre-commencement notification to the local authority (s 38(2)). Eyeball tattooing must be performed only by medical practitioners or prescribed classes (s 39A).

Medical practices and laboratories need standing procedures to identify scheduled and notifiable conditions, complete approved-form certificates within statutory timeframes, and protect Category 5 identity except where disclosure is permitted under s 56(4). Hospitals must have systems ensuring the CEO is informed of notifiable diseases so that the Secretary can be notified (s 83).

Schools and child-care facilities must sight and record immunisation certificates before enrolment (ss 86–87), maintain an up-to-date immunisation register, and be prepared to issue exclusion notices and report outbreaks to the public health officer (s 88).

Organisations likely to receive public health orders should maintain a response protocol that includes immediate legal review, collection of evidence going to the least-restrictive principle, and preparation for NCAT applications. Safe-access-zone compliance for clinics involves physical signage, staff training, and CCTV policies that stay within the s 98E(3) exemptions. Non-registered health practitioners and relevant health organisations must embed the code of conduct prescribed under s 100 into client contracts and advertising.

All entities should designate an authorised-officer liaison person, train staff on obstruction offences (s 116), and keep records in a form that can be produced within the timeframes required by ss 110–111. Regular internal audits against the latest versions of adopted standards and Ministerial orders, combined with prompt engagement with public health officers when improvement notices are received, substantially reduces the risk of escalation to prohibition orders or prosecution. Where uncertainty exists, early requests for Chief Health Officer guidelines or exemptions (e.g. s 25(3)) can clarify obligations before enforcement action is taken.
