The Act introduces a small set of defined concepts that frame the transition. The first is the "old legislative scheme", which is a closed list of seven Acts. Notably, the list does not include every piece of primary industry regulation in Tasmania; it is limited to the Acts that the Biosecurity Act 2019 was designed to replace. The "new legislative scheme" is the combination of the Biosecurity Act 2019 and this Act. The definition is significant because it means the transition is deemed complete only when both instruments are fully in force, but the Biosecurity Act 2019 commences in stages tied to its own schedule, and this Act commences partly at Royal Assent and partly in stages keyed to the Biosecurity Act 2019. The result is that the old scheme is not extinguished all at once.

The "commencement day" is defined as the day this Act receives the Royal Assent, but several sections (6, 7, 8, 9 and their accompanying schedules) do not commence on that day; they commence only when corresponding parts of Schedule 3 to the Biosecurity Act 2019 commence. This staggered commencement means that for some period, parts of the old scheme may remain nominally in force alongside the new framework, creating potential for dual application or gaps. The Act does not itself resolve which scheme prevails during the transition; it leaves that to the transitional regulations.

The most important concept is the regulation-making power under section 4. This is not a standard power to make regulations to carry out the Act; it is specifically a power to make "savings and transitional" regulations consequent on the enactment of the Biosecurity Act 2019. The scope of this power is extraordinarily broad. The regulations may deal with any matter under the old scheme, including decisions, approvals, appointments, bodies, committees, actions, permits, licences, exemptions, registrations, tags, brands, certificates, notices, records, registers, and "any other matter." The list in section 4(2)(b) is non-exhaustive, as indicated by the open-ended paragraph (ix). This means the regulations could, in theory, preserve or abolish anything that existed under the seven repealed Acts. The regulations may also be made retrospectively, apply differently to different circumstances, and confer further decision-making authority on named officials. Critically, section 4(3)(e) allows the regulations to specify that they prevail over inconsistent provisions of the old legislative scheme. This gives the transitional regulations a quasi-legislative power to override the very Acts they are meant to replace, a feature that invites careful scrutiny of the regulations when they are published.

The Act also introduces the concept that transitional regulations can be made either under this Act or as part of regulations under the Biosecurity Act 2019. This is not merely a drafting convenience; it means that the transitional provisions may be dispersed across two sets of regulations, potentially increasing the risk of parties missing relevant provisions.

Finally, the Act contains the standard consequential amendment machinery in Parts 3 and 4, but with a notable provision in section 10: amendments by this Act to any regulation made under any Act do not prevent that regulation from being later amended or rescinded. This preserves the normal regulation-making power and ensures that the amending effect of this Act is not fossilized.

The Act directly affects any person or entity that held rights, obligations, or authorisations under the seven repealed Acts. This includes livestock producers who held brand registrations or movement permits under the Animal (Brands and Movement) Act 1984; animal farmers registered under the Animal Farming (Registration) Act 1994; owners or managers of animals subject to health orders under the Animal Health Act 1995; plant importers, nursery operators, and growers who held quarantine permits under the Plant Quarantine Act 1997; seed producers and traders regulated under the Seeds Act 1985; landholders subject to vermin control notices under the Vermin Control Act 2000; and landowners, occupiers, or public authorities dealing with declared weeds under the Weed Management Act 1999. All these persons now face the question of whether their existing authorisations continue in force.

The Act also affects businesses and individuals in industries that are indirectly referenced through the consequential amendments. For example, the amendment to the Inland Fisheries Act 1995 may affect fishing licence holders; amendments to the Primary Produce Safety Regulations affect egg, meat, poultry, pet food, seafood, and seed sprout producers; and amendments to the Agricultural and Veterinary Chemicals (Control of Use) Act 1995 affect chemical users. However, the text of the consequential amendments is not provided in the source, so the precise effect on each of those Acts is not ascertainable from this Act alone.

Government agencies are directly affected. The administration of the Act is assigned to the Minister for Primary Industries and Water and the Department of Primary Industries, Parks, Water and Environment (section 11), but this assignment is only until an order under the Administrative Arrangements Act 1990 provides otherwise. The Biosecurity Act 2019 establishes new roles such as Chief Veterinary Officer, Chief Plant Protection Officer, and authorised officers, and this Act enables the transitional regulations to delegate further functions to those officers. This means departmental staff must manage the dual system during the transition and be prepared to implement the regulations.

Legal practitioners advising on biosecurity compliance must now refer to the Biosecurity Act 2019 rather than the seven repealed Acts, but they must also check the transitional regulations and any instruments preserved under them. This creates a compliance and advisory burden: the old laws are not simply repealed and gone; their effects may persist via regulations. For example, a permit issued under the old Plant Quarantine Act 1997 might continue in force unless the regulations state otherwise, but the holder cannot know without checking the regulations.

Economically, the Act imposes a one-time compliance cost on all regulated persons to understand the new regime and any transitional rules. For small farmers and agricultural businesses, the cost of legal advice or of time spent reading regulations may be significant relative to the value of the authorisations held. The Act itself does not provide any transitional assistance or a mechanism for automatic conversion of old authorisations to new ones; that is left entirely to regulations. This creates an opportunity for the government to rationalise the authorisation system, but also a risk that some authorisations may be inadvertently lost or that the regulations may impose new conditions without prior consultation.

The Act itself creates no new duties or rights for regulated persons. All substantive duties and rights are found in the Biosecurity Act 2019, which is not included in the source. However, the Act does have significant implications for existing rights and duties under the old legislative scheme.

Existing rights under the repealed Acts are at risk unless preserved by transitional regulations. For example, a person who held a valid permit to import a plant under the Plant Quarantine Act 1997 may lose that right on the repeal of that Act unless the regulations specifically preserve it. Conversely, a person subject to a compliance notice under the Weed Management Act 1999 may find that obligation extinguished unless the regulations carry it over. The Act does not automatically grandfather existing authorisations; it gives the Governor discretion to decide which authorisations continue, and how.

The Act also affects the right to rely on old processes. Under section 4(2)(b)(vii), the regulations may preserve certificates, notices, or other instruments or documents. If preserved, those documents would remain legally effective under the new scheme. If not preserved, they may become void. The same applies to records and registers (section 4(2)(b)(viii)). A person who relied on an old register as evidence of a right (for example, an animal brand registration) may lose that evidence unless the register is continued.

For the government, the Act confers broad powers but also imposes a duty to make regulations to effect the transition. If no regulations are made, the old Acts are simply repealed and there is no mechanism for continuity. This would create legal chaos. Therefore, there is an implicit duty on the executive to issue transitional regulations, but the Act does not set a deadline. The regulations "may" be made; there is no "must". This leaves room for a gap period.

The Act also creates rights in favour of the government through the regulation power. The regulations may authorise the Minister, Secretary, Chief Veterinary Officer, Chief Plant Protection Officer, or an authorised officer to approve, determine, apply, or regulate matters. This means the government can unilaterally make decisions about the transition without further parliamentary scrutiny. Persons affected by those decisions may have limited recourse unless the Biosecurity Act 2019 provides for review of such decisions. The Act does not itself create any merits review or judicial review rights; those would depend on the Biosecurity Act 2019 or general administrative law.

Another important implication: the Act allows regulations to take effect before the day they are made, including before the Act receives Royal Assent (section 4(3)(a)). This retrospective operation could affect rights and duties that arose before the regulations were even contemplated. For example, a person who sold seed without a licence under the old Seeds Act 1985 during the gap period could later be made subject to a requirement that did not exist at the time, if the regulations are worded to apply retroactively. This is a significant incursion into legal certainty, though savings and transitional regulations commonly have retrospective effect to avoid a vacuum.

In summary, the Act erases the old legal landscape and gives the executive a blank page to write transitional rules. Individual rights and duties under the old Acts survive only if and to the extent the regulations say they do. The Act itself does not guarantee continuity.

The Act contains no penalty provisions. It does not create any new offences or increase maximum fines. All enforcement powers, offences, and penalties under the old legislative scheme cease to apply once the old Acts are repealed, unless the transitional regulations preserve them. The regulations may preserve "actions undertaken or exempted" (section 4(2)(b)(iv)), but that is not the same as preserving penalty provisions. Typically, transitional regulations do preserve existing offences for acts committed before repeal, but the Act does not mandate it. If the regulations do not specifically preserve the penalty framework for pre-repeal conduct, prosecutors may lose the ability to enforce old offences.

For enforcement officers, the Act affects which legal framework they use. After commencement, any enforcement action must be taken under the Biosecurity Act 2019, which has its own set of powers: powers of entry, search, seizure, directions, and penalties. The old Acts' enforcement provisions are gone. However, the transitional regulations may preserve certain enforcement instruments, such as notices or orders that were already issued under the old Acts. The regulations could also extend the operation of old notices into the new scheme. This means a person who was already subject to a weed control notice under the Weed Management Act 1999 may still be required to comply after repeal, but the enforcement consequence for non-compliance may now be under the Biosecurity Act 2019.

The Act itself does not specify any transitional enforcement difficulty. For example, if an old permit contained conditions that are not carried over into the new scheme, a person who relied on the old conditions might inadvertently breach the new Act if the Biosecurity Act 2019 imposes stricter requirements. The Act does not provide transitional protection against such inadvertent breaches.

In terms of enforcement priority, the Act assigns administration to the Minister for Primary Industries and Water, but the day-to-day enforcement would be carried out by authorised officers under the Biosecurity Act 2019. The transitional regulations may designate certain existing officers under the old Acts as authorised officers for the purposes of the new scheme, but again, that depends on the regulations.

The Act also amends several other Acts via Schedules. For example, Schedule 4 amends the Criminal Code Act 1924 and the Firearms Act 1996, among others. Without the text of those amendments, we cannot say whether those amendments create new penalties or modify existing ones in the context of biosecurity. But the amendment of the Criminal Code suggests that the transition may affect criminal liability for biosecurity offences.

In short, this Act is penalty-neutral. All enforcement consequences flow from the Biosecurity Act 2019 and the transitional regulations. The key risk for regulated persons is that the transitional regulations may recreate old offences or create new ones with retrospective effect. The Act does not prohibit that, so it is possible that a person could face a penalty for conduct that was lawful under the old Act or during the gap period.

This Act is designed to interact with the Biosecurity Act 2019 as its primary partner. The two together form the "new legislative scheme". The Act does not operate independently; it is purely ancillary to the commencement of the Biosecurity Act 2019. Its interaction with other laws is mediated through the consequential amendments in Schedules 1 through 5, and through the transitional regulations.

The consequential amendments listed in Schedule 1 affect five primary produce safety regulations (Egg, Meat and Poultry, Pet Food, Seafood, Seed Sprouts) and the Inland Fisheries Act 1995. This means that references in those regulations or that Act to the old Acts are likely being updated to refer to the Biosecurity Act 2019 or to the new framework. Without the text, we cannot know the details, but the effect is to align those instruments with the new biosecurity regime.

Schedule 2 amends the Approvals (Deadlines) Act 1993 in relation to the Animal (Brands and Movement) Act 1984. This is a narrow technical amendment likely to update references or transitional arrangements for approvals that were subject to deadlines under the old Act.

Schedule 3 amends the Animal Farming (Registration) Act 1994 itself, the Biosecurity Act 2019, and the Nature Conservation Act 2002. Amending the Biosecurity Act 2019 via this Act suggests there may be cross-references or transitional provisions inserted into the Biosecurity Act 2019. Amending the Nature Conservation Act 2002 may align its definitions or biosecurity-related duties.

Schedule 4 is the most extensive, amending eleven Acts including the Agricultural and Veterinary Chemicals (Control of Use) Act 1995, the Animal Welfare Act 1993, the Criminal Code Act 1924, the Firearms Act 1996, and the Vermin Control Act 2000 (which is itself being repealed). The amendment to the Criminal Code is particularly notable: it suggests that biosecurity offences may intersect with criminal law, perhaps by updating references to repealed Acts in existing criminal provisions. The amendment to the Firearms Act may relate to provisions about possession of firearms for pest control purposes, which were previously covered by the Vermin Control Act 2000.

Schedule 5 amends the Biosecurity Act 2019 (again), the Boundary Fences Act 1908, the Rail Infrastructure Act 2007, the Roads and Jetties Act 1935, and the Weed Management Act 1999 (which is also being repealed). The amendments to the Boundary Fences Act 1908 and the Roads and Jetties Act 1935 likely update references to weed management responsibilities along boundaries and road reserves.

The Act also interacts with the Administrative Arrangements Act 1990, which will supersede section 11's assignment of administration once an order is made under that Act. This means that the portfolio responsibility may shift over time.

The transitional regulations may also interact with other laws. The regulations may authorise the Chief Veterinary Officer or Chief Plant Protection Officer to make decisions, and those decisions may be subject to review under the Biosecurity Act 2019 or under general administrative law such as the Judicial Review Act 2000 (Tas). The Act does not address that explicitly, but the interaction is implicit.

A key interaction is with common law property rights. The Vermin Control Act 2000 and the Weed Management Act 1999 both allowed authorities to enter private land and compel landholders to take action at their own cost. The transition may affect extant compliance notices; if those notices are continued via regulations, they remain enforceable but under the enforcement regime of the Biosecurity Act 2019. If not continued, landholders may be released from those obligations, but may also lose certain rights to compensation that existed under the old Acts.

Overall, the Act is a legislative clean-up tool. Its effect on any specific other law depends heavily on the text of the consequential amendments, which are not reproduced in the source. Practitioners must consult the actual amending schedules as enacted to understand the precise changes.

The source text is the Act as in force on 12 April 2026. No amendment history is provided within the source. The Act itself is a 2020 enactment, so any amendments between 2020 and 2026 are not shown. The commencement provisions in section 2 indicate that the Act came into force in stages, with the main transitional provisions (section 4) commencing at Royal Assent, and the consequential amendment schedules (Schedules 2 through 5) commencing at dates tied to the commencement of the Biosecurity Act 2019. That means the Act's operation had a phased start. The current in-force version as of the source date presumably reflects all commenced provisions. Without amendment notes, we cannot state whether any sections have been added, repealed, or modified. The Act appears to be a standard transitional Act that is unlikely to be amended frequently, but that cannot be confirmed from the source.

The Act's long title and structure suggest it was intended as a one-time enactment. Once the transition is complete, the substantive role of this Act will be spent, though the regulations continue to have effect. There is no sunset clause in the Act itself; it remains on the statute book even after the transition is complete. This means the regulation-making power in section 4 could theoretically be used to further regulate transitional matters long after the transition, but that would be unusual and possibly beyond the stated purpose. The Act does not limit the period during which regulations can be made.

The source contains no reference to any litigation, either pending or decided. This is unsurprising for a transitional Act of this nature. However, the absence of litigation history in the source does not preclude the existence of cases interpreting this Act. The source is only the Act itself, not a judicial database.

Potential areas of litigation could include challenges to the validity of transitional regulations, especially if they are retrospective or conflict with the old Acts without clear authority. Section 4(3)(e) allows regulations to prevail over inconsistent provisions of the old legislative scheme, but that may be challenged on the ground that the enabling provision itself is ultra vires if the regulations go beyond "savings and transitional" matters. Another litigation risk is around the preservation of authorisations: if a person's permit is inadvertently not preserved, they may argue that the regulation fails to give effect to a legitimate expectation or that the regulation is unreasonable.

Also, if the transitional regulations delegate decision-making to the Minister or an officer and that decision is adverse, judicial review may be sought under the Administrative Decisions (Judicial Review) Act 1989 (Cth) if applicable, or under Tasmania's Judicial Review Act 2000. The Act does not contain any privative clause or restrict review.

Another possible source of litigation is confusion over whether a particular right or obligation survived the repeal. For example, if a prosecution is brought under a repealed Act for conduct before repeal, the validity of the prosecution may depend on the transitional regulations preserving that offence. If the regulations are silent, the prosecution may fail under standard principles of statutory interpretation (repeal of a penal Act extinguishes liability). That could lead to appeals and potentially constitutional arguments about the fairness of retrospective operation.

Without case citations in the source, we cannot provide any specific cases. The analyst must consult Tasmanian law reports and databases for any litigation under this Act. Given the Act's age (2020) and its transitional nature, litigation may have already occurred.

The most significant gotcha is the breadth of the regulation-making power in section 4. The Governor may make regulations that preserve, vary, or revoke "any other matter" under the old scheme. This is a blank cheque. There is no legislative guidance on what criteria the Governor should apply: no requirement to consult, no requirement to publish a draft, no requirement to ensure continuity, and no requirement to avoid imposing new burdens. The regulations can also be retrospective, which creates risk for persons who acted in the gap between the repeal of the old Acts and the making of the regulations.

A second gotcha is that the transitional regulations may be made either under this Act or as part of the Biosecurity Act 2019 regulations. This dual location means a person who checks only the Biosecurity Act 2019 regulations may miss transitional provisions that are made under this Act, and vice versa. The Act does not require a single consolidated instrument.

Third, the Act does not guarantee that existing permits, licences, or registrations continue. Many regulated persons assume their permits are grandfathered, but they may be wrong if the regulations do not preserve them. The Act itself contains no grandfather clause. The only mechanism for preservation is the regulation power, and that power is discretionary.

Fourth, the Act allows regulations to authorise a wide range of officials to "approve, determine, apply or regulate" matters. This sub-delegation means that the actual decisions affecting a person's rights may be made by an authorised officer rather than by Parliament or even the Minister. The criteria for those decisions are not set out in the Act; they must be in the regulations themselves, and if the regulations are silent, the officer may have unfettered discretion.

Fifth, the staggered commencement creates a potential legal limbo. For example, if a section of this Act commences only when a corresponding part of the Biosecurity Act 2019 commences, and that part of the Biosecurity Act 2019 has not yet commenced, then the consequential amendment in the schedule is not yet in force. This means the old Act remains in force for that purpose, while other parts of the old Act may have already been repealed by other commenced provisions. This could lead to a fragmented and confusing patchwork where some provisions of an old Act are repealed and some are not, depending on the commencement schedule.

Sixth, the Act does not provide any transitional period for compliance with new requirements. If a person held an old permit that did not require a particular condition, and the new Biosecurity Act 2019 imposes that condition, the person may be in breach immediately if the transitional regulations do not grant a grace period.

Seventh, the administration assignment in section 11 is only until an order under the Administrative Arrangements Act 1990 provides otherwise. This creates uncertainty about which Minister and department will ultimately be responsible. If the order changes the portfolio, regulated persons may face a change in enforcement priorities and contact points.

Finally, the Act amends the Criminal Code Act 1924. Without seeing the text, this raises a red flag: any amendment to the Criminal Code can potentially affect the classification of offences and associated penalties. A person could be exposed to criminal liability for biosecurity breaches that were previously only civil or regulatory offences.

Since the Act itself imposes no duties, compliance means ensuring that one's rights and obligations under the old Acts are properly transitioned to the new regime. The first step is to identify any authorisations, permits, licences, exemptions, registrations, or other approvals held under any of the seven repealed Acts. The second step is to locate the transitional regulations made under section 4 of this Act. These regulations will determine whether each authorisation continues, in what form, and for how long.

The transitional regulations are the single most important compliance document. They must be read carefully. They may preserve the authorisation with modifications, require re-application, or set a sunset date. They may also impose new conditions. The regulations may be found either as regulations under this Act or as part of the Biosecurity Act 2019 regulations. It is prudent to search both.

One should also check if the Biosecurity Act 2019 itself contains transitional provisions that apply directly. The Act defines the new legislative scheme as including the Biosecurity Act 2019, which may have its own transitional schedule. If the Biosecurity Act 2019 contains a general savings clause (such as "anything done under a repealed Act continues in force"), that may override the need for specific regulations, but that cannot be assumed.

For landholders subject to weed or vermin control notices issued under the old Acts, check whether the transitional regulations continue those notices. If not, the notice is likely extinguished and the landholder may have no further obligation, but be aware that the new Biosecurity Act 2019 may separately empower authorities to issue equivalent notices.

For businesses that rely on animal brands, movement records, or registration lists, verify that the relevant register is continued. If the register is not preserved, historical records may become unreliable for proving ownership or compliance.

For producers in the egg, meat, poultry, pet food, seafood, and seed sprout sectors, the consequential amendments to the primary produce safety regulations may change which biosecurity standards apply. Review those amended regulations.

Engage with the administering department (the Department of Primary Industries, Parks, Water and Environment, until otherwise ordered) for guidance. The department may issue administrative guidance or fact sheets about the transition. However, reliance on informal guidance does not guarantee legal protection if the regulations say otherwise.

Monitor the Tasmanian Legislation website for changes to the transitional regulations. The Act does not require a review period, but the regulations may be amended. Also note that section 4(3)(a) allows regulations to take effect before they are made, so a regulation published today could theoretically operate from a date months earlier. This is a risk for anyone who assumed the old law still applied during the gap.

Finally, if there is any doubt whether an old authorisation survives, seek legal advice or apply for a new authorisation under the Biosecurity Act 2019. The Biosecurity Act 2019 may allow for fresh applications that are more straightforward than deciphering the transitional rules. The cost of applying anew may be lower than the cost of non-compliance if a permit is mistakenly thought to remain valid. The Act does not provide compensation for inadvertent loss of rights due to the transition. Prudence favours proactive confirmation of one's status.
