The central concept is the applied provisions , defined in section 4 as the Commonwealth water efficiency laws that apply as a law of Tasmania because of section 6, including any modification under section 7. This is not a static incorporation; it is dynamic. The phrase 'as in force for the time being' in section 6(1) means that future changes to the Commonwealth Act and regulations automatically become part of Tasmanian law without further legislative action. The only qualification is that the Tasmanian regulations may specify that a particular Commonwealth amendment is not to take effect for state purposes (section 7(2)(b)). This creates a one-way ratchet: the default is automatic adoption, but the state can opt out of specific amendments.

The Commonwealth Regulator is the WELS Regulator appointed under the Commonwealth Act. Under section 9, that Regulator and other Commonwealth authorities and officers have the same functions and powers under the applied provisions as they have under the Commonwealth Act. Delegations by the Commonwealth Regulator under the Commonwealth Act are taken to extend to the corresponding provision of the applied provisions (section 10). This means a single regulator administers both the Commonwealth scheme and the Tasmanian adopted scheme, avoiding duplication of enforcement bodies.

The Act uses a fiction of Commonwealth law for criminal and administrative purposes. Section 12(1) provides that relevant Commonwealth criminal laws apply as laws of Tasmania in relation to an offence against the applied provisions as if those provisions were a Commonwealth law and not a state law. For state law purposes, an offence against the applied provisions is taken to be an offence against Commonwealth laws and not a state offence (section 12(2)). Similarly for administrative matters under section 15. This treatment is subject to exception by Tasmanian regulations (sections 12(3) and 15(3)). The practical effect is that the Commonwealth criminal justice system , including investigation, prosecution, bail, trial, sentencing, fines, and proceeds of crime , applies to breaches of the WELS scheme in Tasmania.

Double jeopardy protection is explicitly provided in section 14. If an act or omission is an offence against both the Tasmanian Act and the Commonwealth Act, and the offender has been punished under the Commonwealth Act, they are not liable to be punished under the Tasmanian Act. Similarly, payment of a pecuniary penalty under the Commonwealth Act bars a pecuniary penalty under the Tasmanian Act for the same conduct. This prevents being penalised twice by different jurisdictions for the same conduct.

The Act directly affects any person or business in Tasmania that manufactures, imports, supplies, sells, or installs water-using products and appliances covered by the WELS scheme. The Commonwealth Act and its regulations specify which products are subject to registration and labelling requirements , typically toilets, taps, showers, urinals, washing machines, dishwashers, and flow controllers. The Tasmanian Act itself does not list those products, but by adopting the Commonwealth law, all those obligations apply in Tasmania as a matter of state law.

The Act binds the Crown in right of Tasmania and, so far as legislative power permits, in all other capacities (section 5). This means state government departments and agencies that purchase or supply water-using products must comply with the WELS requirements. It is unclear from the Act whether the Crown in right of the Commonwealth or other states is bound, but the provision limits the extent to state legislative power.

The Commonwealth Regulator and Commonwealth officers and authorities are primary operators under this Act. They have functions and powers under the applied provisions (section 9) and under criminal and administrative laws (sections 13 and 16). They must act as nearly as practicable as they would under the equivalent Commonwealth provisions. This imposes an obligation on Commonwealth officers to apply consistent standards across jurisdictions.

The Act also affects legal practitioners and courts in Tasmania. Because offences against the applied provisions are treated as Commonwealth offences for state law purposes, prosecution will be by Commonwealth bodies (such as the CDPP) in state courts exercising federal jurisdiction? However, section 15(4) removes any federal court jurisdiction that might arise from the application of Commonwealth administrative laws. Offences against the applied provisions are not automatically federal offences; rather, they are state offences that are treated as Commonwealth offences through the fiction in section 12. The investigation and prosecution will be conducted under Commonwealth criminal laws that apply as state laws, likely by Commonwealth agencies. The sentencing court will apply Commonwealth sentencing laws.

Suppliers and retailers in Tasmania must ensure that their products are registered, correctly labelled with a water efficiency star rating, and that they do not supply unregistered or incorrectly labelled products. Advertisers and marketers must avoid false or misleading water efficiency claims. Importers bringing products into Tasmania for sale must comply. Consumers are indirectly affected through the information provided by labels, though the Act does not create consumer rights , it is primarily a regulatory scheme.

The Act does not itself set out the substantive duties and rights; these arise from the applied provisions (the Commonwealth Act and regulations). However, the Tasmanian Act creates the legal framework that makes those duties enforceable in Tasmania. The key duties under the Commonwealth scheme include:

Registration duty. A supplier of a water-using product covered by a WELS determination must register the product with the Regulator before supplying it. The registration process requires providing water consumption data and paying a fee. Registration confirms the product meets the relevant water efficiency standard.

Labelling duty. Registered products must bear a WELS label showing the star rating (from 0 to 10 stars), water consumption per use or per cycle, and other prescribed information. The label must comply with the design, size, colour and placement requirements in the regulations. Unregistered products must not carry a WELS label or a mark that resembles it. It is an offence to supply a registrable product without a label or with a false label.

Supplier obligations. Suppliers must not supply a registrable product unless it is registered and correctly labelled. They must also ensure that products supplied comply with any applicable water efficiency, flow rate or performance standards prescribed in the regulations. This may include testing requirements. Suppliers must also keep records of compliance.

Information duties. The Regulator has powers to require the production of documents, to enter premises and inspect products, to purchase samples, and to require information from suppliers. The applied provisions, combined with the application of Commonwealth administrative laws, give the Regulator these powers.

Rights of affected persons. Under the applied administrative laws, a person aggrieved by a decision of the Regulator under the applied provisions (such as a refusal to register a product, cancellation of registration, or issuance of an infringement notice) has review rights. The Administrative Review Tribunal Act 2024 (Cth) applies as a state law for reviews of decisions under the applied provisions (section 15). This gives a right to apply to the ART for merits review. The Ombudsman Act 1976 gives complainants a right to have the Regulator’s administrative actions investigated. The Freedom of Information Act 1982 gives rights to access documents held by the Regulator relating to compliance and enforcement. The Privacy Act 1988 gives individuals rights to access and correct personal information held. These are all available as if the applied provisions were Commonwealth law.

No double jeopardy right. Section 14 gives a right not to be punished twice for the same conduct. If someone is penalised under the Commonwealth scheme, they cannot be penalised again under the Tasmanian scheme for the same act. This is a significant protection for regulated entities.

Penalties under the Act are those imposed by the Commonwealth water efficiency laws as applied. The Commonwealth Act and its regulations prescribe maximum penalties for offences such as supplying unregistered products, failing to label, making false statements, or obstructing an inspector. These penalties are enforceable in Tasmania through the mechanism in Part 4 of the Tasmanian Act. Section 12 applies Commonwealth criminal laws as state laws, which means the Criminal Code Act 1995 (Cth) and other federal criminal procedure laws apply to investigations and prosecutions of WELS offences in Tasmania. This includes provisions on fault elements, corporate criminal responsibility, penalties, and sentencing.

The Act provides that fines and penalties paid are to be paid to the Commonwealth (section 19). This is unusual for a state Act , normally penalties go to the state Consolidated Fund. It underscores the uniform national scheme design: the Commonwealth bears the cost of enforcement and receives the revenue from penalties, avoiding any incentive for Tasmania to prosecute merely for revenue.

Enforcement is carried out by the Commonwealth Regulator and Commonwealth officers. Section 13 confers on them the same functions and powers in relation to offences against the applied provisions as they have under the Commonwealth Act. This includes powers of investigation, search and seizure (subject to warrant requirements under Commonwealth law), and the power to issue infringement notices for minor breaches. Section 13(2) requires that they act as nearly as practicable as they would under the Commonwealth Act, ensuring consistency.

Civil penalties are also available under the Commonwealth Act. The Tasmanian Act treats a 'civil breach that gives rise to a civil penalty' as an offence for the purposes of the Act (see definition of 'offence' in section 4). This means the same double jeopardy protection in section 14 applies to civil penalties. If a civil penalty has been paid or ordered under the Commonwealth Act, no civil penalty can be imposed under the Tasmanian Act for the same conduct.

The double jeopardy protection (section 14) is explicit: if someone has been punished for an offence under the Commonwealth Act that is also an offence under this Act, they are not liable to be punished under this Act. Similarly for pecuniary penalties. This prevents Commonwealth and state authorities from pursuing separate penalties for the same breach, but it also means that if the Commonwealth has not acted, the state could proceed. However, because the Commonwealth Regulator is the same body, in practice enforcement is likely coordinated to avoid duplication.

The Act explicitly disengages standard Tasmanian interpretation rules from the applied provisions. Section 8(3) provides that the Acts Interpretation Act 1931 (Tas) does not apply to the applied provisions. Instead, the Acts Interpretation Act 1901 (Cth) applies as a state law for interpreting the applied provisions (section 8(1)). This ensures consistent interpretation across jurisdictions. Practitioners interpreting the applied provisions must use Commonwealth interpretation principles, not Tasmanian ones, even though the provisions are state law.

The Act also supersedes previous Tasmanian regulation of water efficiency labelling. Schedule 1 repeals the Water Efficiency Labelling and Standards Act 2005 (Tas) (the earlier state Act). Schedule 2 revokes the Proclamation under that earlier Act. This is a complete replacement of the state scheme with the applied Commonwealth scheme.

Relations with the Commonwealth Act itself: the Tasmanian Act does not repeal or affect the Commonwealth Act's operation in Tasmania. Both can apply concurrently, but the double jeopardy provisions prevent double punishment. The Commonwealth Act applies as Commonwealth law in Tasmania; the Tasmanian Act applies the Commonwealth Act as state law. A single set of conduct might breach both, but only one penalty is payable. The Act also provides in section 17 that things done for multiple purposes (e.g. a licence issued under both Commonwealth and state schemes) are not invalid merely because they serve both.

Commonwealth administrative laws apply to the applied provisions (section 15). This means that decisions under the applied provisions are subject to the Administrative Review Tribunal, FOI, Ombudsman and Privacy Acts as if they were Commonwealth decisions. However, section 15(4) expressly removes any jurisdiction that those laws would purport to confer on a federal court. So the Federal Court does not acquire jurisdiction over decisions under the applied provisions. Judicial review of decisions under the applied provisions would be available under the Judiciary Act 1903 (Cth)? Possibly not because the applied provisions are state law. More likely, judicial review would be under the Tasmanian Judicial Review Act 2000 or common law, but the Act creates an unusual hybrid. In practice, merits review through the ART and potential judicial review in the Supreme Court of Tasmania would be the avenues, though the Act is silent on this.

For Crown law purposes, section 5 binds the Crown in right of Tasmania. The Crown in other capacities is bound only so far as legislative power permits. This affects government procurement: state government suppliers must comply. It does not bind the Commonwealth Crown directly.

The Act interacts with the Competition and Consumer Act 2010 (Cth) indirectly. The WELS scheme is part of a broader regulatory framework under the Water Efficiency Labelling and Standards Act 2005 (Cth), which is a Commonwealth Act. The Tasmanian Act does not affect the Australian Consumer Law (ACL). However, false or misleading water efficiency claims could attract liability under the ACL as well as under WELS. The enforcement agencies could cooperate.

The Act received Royal Assent on a date not specified in the text, but given it commenced on Royal Assent (section 2), it came into force on that date. The principal amendment evident from the extracted text is by No. 8 of 2025, which amended sections 4 and 15. Specifically, in the definition of 'Commonwealth administrative laws' in section 4, the reference to the Administrative Review Tribunal Act 2024 (Cth) replaced an earlier reference to the Administrative Appeals Tribunal Act 1975 (Cth). This is indicated by the editorial note '[Section 4 Subsection (1) amended by No. 8 of 2025, s. 34, Applied:14 Oct 2024]'. Similarly, section 15(5) was amended by the same Act (section 35) to update a reference from the old AAT Act to the new ART Act. The amendment is stated as 'Applied:14 Oct 2024', which likely means the amendment commenced on 14 October 2024, superseding the Tasmanian Act's earlier reference.

The Act itself repealed and replaced an earlier Tasmanian Act of the same name from 2005 (Schedule 1). That earlier Act was a stand-alone state statute, not a direct copy of the Commonwealth Act. The 2013 Act adopted the Commonwealth Act as applied law, moving away from independent state legislation. The Proclamation under the 2005 Act was also revoked (Schedule 2).

The Act has been amended at least once. The amendment by No. 8 of 2025 updated the administrative review body reference to the new Administrative Review Tribunal, which replaced the Administrative Appeals Tribunal from October 2024. This maintains alignment with the Commonwealth administrative law framework. The text does not indicate any other amendments.

The source text does not name any cases, and we cannot invent them. However, the structure of the Act suggests certain litigation patterns. Offences against the applied provisions are treated as Commonwealth offences for state law purposes, so prosecutions would occur in Tasmanian courts applying Commonwealth criminal laws. Cases involving the interpretation of the applied provisions would be litigated in state courts. Given the applied interpretation provision (section 8), courts would need to apply the Acts Interpretation Act 1901 (Cth) and federal case law on interpretation.

The double jeopardy provisions in section 14 could generate litigation if a person is prosecuted under both the Commonwealth Act and the Tasmanian Act for the same conduct. The Act provides a defence, but it would require proof that punishment has already been imposed under the Commonwealth Act.

Civil penalty proceedings could also arise. The applied provisions likely contain civil penalty provisions (the Commonwealth Act does). Those would be enforced in Tasmanian courts applying Commonwealth civil penalty principles.

The application of Commonwealth administrative laws raises questions about the jurisdiction of the Administrative Review Tribunal in relation to state law. The ART can review decisions under the applied provisions because those provisions are deemed to be Commonwealth law for the purposes of the ART Act. The actual practice of ART review of WELS decisions in relation to Tasmanian matters is likely consistent with Commonwealth WELS decisions.

One potential litigation issue is the interaction with the repeal of the earlier Tasmanian Act. Any transition issues , such as existing registrations under the old Act , would need to be addressed, but the Act does not contain transitional provisions in the extracted text.

Overall, the Act itself is not highly litigated. Its function is to adopt a Commonwealth scheme, so most litigation will involve the substantive provisions of the Commonwealth Act and regulations, not the machinery of adoption.

Automatic adoption of future Commonwealth amendments. Section 6(1) applies Commonwealth water efficiency laws 'as in force for the time being'. This means if the Commonwealth Parliament passes an amendment to the WELS Act or makes new regulations, those changes automatically become part of Tasmanian law on the day they commence at the Commonwealth level. Section 20 requires tabling within 10 sitting days, but does not suspend operation. There is no requirement for the Tasmanian Parliament to approve. This is a significant delegation of legislative power to the Commonwealth. A business in Tasmania could be bound by a new standard or registration requirement imposed by the Commonwealth without any scrutiny by the Tasmanian Parliament. The only escape is if Tasmanian regulations are made to modify or exclude the amendment (section 7(2)).

Modification power is asymmetric. The Tasmanian regulations may modify the Commonwealth water efficiency laws for the purposes of this Act (section 7(1)). This includes the power to specify that a particular Commonwealth amendment 'had not taken effect' (section 7(2)). However, this power is exercised by the Tasmanian Governor in Council, not by the Commonwealth. If the Commonwealth makes a change that Tasmania disagrees with, the state must make its own regulations to opt out. That requires executive action in Tasmania. If no such regulations are made, the Commonwealth change applies. This creates a risk of regulatory divergence: if Tasmania does opt out, the uniform scheme breaks down, and businesses in Tasmania may be subject to different rules than those in other states.

Fees paid to the Commonwealth. All fees, penalties, fines and other money payable under the Act and the applied provisions must be paid to the Commonwealth (section 19). This means that if a Tasmanian supplier pays a registration fee or a penalty, the money goes to the Commonwealth Consolidated Revenue, not to Tasmania. For a supplier, this may not matter directly, but it means the Tasmanian government does not directly benefit from enforcement or registration activities. There is no incentive for Tasmania to vigorously enforce the scheme, which could lead to lower compliance monitoring in Tasmania compared to states that retain the fees. Conversely, it avoids Tasmania treating enforcement as a revenue raiser.

Double jeopardy only one way. Section 14 protects a person from punishment under the Tasmanian Act if they have already been punished under the Commonwealth Act. It does not protect against being punished under the Commonwealth Act if first punished under the Tasmanian Act. The text of section 14(1)(b) requires 'the offender has been punished for the offence under the Commonwealth Act'. It does not address the reverse scenario. In theory, if Tasmania prosecutes first, the Commonwealth could still prosecute for the same conduct. However, in practice the Commonwealth Regulator coordinates enforcement. The safer interpretation is that the double jeopardy provision only bars Tasmanian action after Commonwealth action, not vice versa. A prudent entity should ensure any settlement or plea includes a release from both jurisdictions.

No federal court jurisdiction for administrative matters. Section 15(4) provides that any provision of a Commonwealth administrative law that purports to confer jurisdiction on a federal court is taken not to have that effect. This means judicial review of Regulator decisions under the applied provisions cannot be sought in the Federal Court under the Administrative Decisions (Judicial Review) Act 1977 (Cth) or under the ART Act's court provisions. The appropriate forum would be the Supreme Court of Tasmania. This may come as a surprise to litigants familiar with Commonwealth judicial review.

Commonwealth interpretation rules apply. Tasmanian interpretation legislation does not apply to the applied provisions (section 8(3)). Instead, the Acts Interpretation Act 1901 (Cth) applies as state law. This affects how terms, definitions, references, and headings are interpreted. Practitioners must use Commonwealth precedents, not Tasmanian ones, when construing the applied provisions.

Compliance with the Tasmanian Act is effectively compliance with the Commonwealth WELS scheme. There is no separate Tasmanian registration process or additional labelling requirement. The steps are:

Identify whether your product is covered. Check the WELS determinations made under the Commonwealth Act. These currently cover toilets, washing machines, dishwashers, clothes washers, showers, taps, flow controllers, urinals, and some other water-using appliances. The Commonwealth website (administered by the Department of Climate Change, Energy, the Environment and Water) maintains the current list. If your product is not covered, no WELS obligations apply (though other water efficiency regulations may).

Register your product with the WELS Regulator. Before supplying a registrable product in Tasmania, you must register it with the Commonwealth Regulator. Registration involves submitting water consumption test results from an accredited laboratory, paying the prescribed fee, and providing product details. Registration is valid for a period (typically 5 years) and must be renewed. Registration is product-specific, not supplier-wide.

Ensure correct labelling. Each registered product must bear a WELS label. The label must display the star rating (using the standard 0-10 star graphic), the water consumption in litres per use or per cycle, and the model name/number. The label must be affixed to the product at the point of supply. For products sold online, the label image must be displayed on the product page. The label design and specifications are set out in the WELS Standard (AS/NZS 6400) as referenced in the regulations.

Do not supply unregistered or incorrectly labelled products. It is an offence to supply a registrable product that is not registered and labelled. This includes display models, free samples, and products sold through online platforms. Importers and distributors must ensure their supply chain complies. A supplier who purchases from a manufacturer that has already registered the product does not need to re-register, but must ensure the product still bears the correct label. If the label is missing or damaged, the supplier must not supply it until relabelled.

Maintain records. Keep records of registrations, test reports, and labelling compliance. The Regulator may request these. Failure to maintain records can be an offence.

Respond to Regulator inquiries. The Regulator has powers to request information, inspect premises, and take samples. Co-operation is mandatory. Obstructing an inspector carries penalties.

Handle variations and renewals. If a product's water consumption changes (e.g. through design changes), re-registration may be required. Register the new model before supplying it. Renew registrations before expiry.

Monitor Commonwealth amendments. Because the Tasmanian Act automatically adopts Commonwealth amendments, you must keep up with changes to Commonwealth regulations that may affect your products. Subscribe to the WELS Regulator's mailing list. When a new determination is made covering additional products (e.g. currently proposed for heating and cooling products), you must comply from the commencement date.

Seek legal advice on borderline products. If you are unsure whether a product is registrable, check the WELS website or contact the Regulator. Erring on the side of non-registration carries enforcement risk. Registration fees are modest relative to penalties.

Note that compliance with the Tasmanian Act is the same as compliance with the Commonwealth Act. There is no double compliance burden. If your product complies with the Commonwealth scheme, it complies in Tasmania. The main administrative interface is with the Commonwealth Regulator, not with any Tasmanian authority.
