Biosecurity (First Point of Entry—Port of Point Wilson) Determination 2025

The instrument rests on a small set of statutory and operational concepts drawn from the Biosecurity Act 2015 and the instrument’s own definitions.

First point of entry. The instrument designates a geographical port as a first point of entry for particular vessels and goods. This is a statutory classification that determines where biosecurity control obligations attach on arrival. The instrument declares that Port of Point Wilson is a first point of entry for vessels other than non‑commercial vessels and passenger vessels (section 5) and for certain goods (section 6). The note to section 6 expressly limits the port to the listed goods only.

Biosecurity entry point. The instrument identifies the physical location within the port that functions as the operational entry point for biosecurity purposes, by mapping classes of vessels and classes of goods to Point Wilson Wharf (sections 7 and 8). The tables in sections 7 and 8 set the operational locus where vessels and goods subject to biosecurity control must be brought, and the instrument points readers to sections 147 and 246 of the Act by note for the statutory requirement to bring vessels/goods to the relevant entry point as soon as practicable (notes to sections 7 and 8).

Classes of vessels and goods. The instrument distinguishes by class rather than by individual vessel name or cargo. Vessels in scope are "vessels other than non‑commercial vessels and passenger vessels" (section 5; section 7 table, Column 1). Goods in scope are limited to baggage carried on covered vessels, freight containers (specifically defined as enclosed 6‑sided 20‑ or 40‑foot re‑usable containers able to transfer between modes without unloading), and waste defined by the intendment to dispose by the person in charge of the vessel (section 4; section 6).

Notification and change controls. The instrument makes the designation conditional on ongoing administrative communication with the Agriculture Department. Owners and lessees have an obligation to give written notice as soon as practicable when they become aware of a change to the business entity operating the port or a biosecurity entry point (sections 9(2) and 9(3)). Persons or bodies responsible for operations must give reasonable written notice of proposed changes to procedures, facilities or other things that may affect biosecurity risk (sections 9(4) and 9(5)). The list in section 9(5) is prescriptive about the kinds of changes that attract the notice obligation: procedural changes to biosecurity measures, changes to facilities or amenities for officials, changes affecting risk identification or the ability to inform officials about identified risks, and changes to procedures managing other contributory factors.

Delegation and legal source. The instrument was made by a delegate of the Director of Biosecurity and expressly records the instrument is made under subsection 229(1) of the Act (section 3). The commencement mechanics are specified in section 2, which places the operative commencement on the day after registration.

Cross‑references. The instrument contains explicit notes pointing users to other provisions of the Biosecurity Act 2015: sections 173 and 174 for matters relating to prohibited goods and conditionally non‑prohibited goods (note to section 6), section 246 regarding bringing an arrived vessel to a biosecurity entry point (note to section 7), and section 147 regarding bringing unloaded goods to a biosecurity entry point (note to section 8). These references indicate how the instrument is intended to function within the Act’s larger regulatory scheme, but the instrument itself does not restate those sections.

Definitions that shape scope. The instrument’s own definition of freight container (section 4) narrows the class of containers covered to standard 20‑foot and 40‑foot enclosed reusable containers capable of multimodal transfer without unloading. The definition of goods ties to the Act’s definition but limits covered goods to those subject to biosecurity control or an exposed goods order (section 4). The defined term waste is contextual and hinges on the intention of the person in charge of the vessel (section 4).

Collectively, these concepts determine which actors and operations in the port environment are drawn into the statutory biosecurity framework created by the instrument and what administrative communications are required to maintain the designation.

The instrument creates obligations and operational consequences for several identifiable groups; the provisions specify who carries duties and which arrivals are captured.

Port owners and lessees. Section 9 places express duties on the owner (or, where there is more than one, an owner) and on a lessee (or, where there is more than one, a lessee) of Port of Point Wilson. Those parties must give written notice to the Agriculture Department as soon as practicable after becoming aware of an actual or impending change to the business entity operating the port or a biosecurity entry point (sections 9(2) and 9(3)). This imposes an ongoing administrative obligation on property owners and lessees and therefore on the organisations that hold title or leasehold interests in the port.

Persons or bodies responsible for carrying out operations at the port. Section 9(4) places a pre‑change notice obligation on the person or body responsible for operations at the port. That actor must give the Agriculture Department reasonable written notice of proposed changes listed in section 9(5). The instrument does not define “person or body responsible for carrying out operations”, so an operational responsibility will likely fall to the port operator, terminal operator, stevedore, or similar service provider in practice.

Ship operators and masters. The designation of Port of Point Wilson as a first point of entry for vessels other than non‑commercial and passenger vessels (section 5) and the designation of Point Wilson Wharf as the biosecurity entry point for those vessels (section 7) affect commercial ship operators, vessel masters and agents whose vessels enter Australian waters and are subject to biosecurity control. The instrument’s notes reference sections 246 and 147 of the Act for the duty to bring arrived vessels and goods to the relevant biosecurity entry point as soon as practicable (notes to sections 7 and 8), which operationally affects routing, berthing and cargo handling, though the Act’s text is not reproduced here.

Freight operators and importers. The instrument directly captures freight containers, baggage on relevant vessels, and waste as classes of goods for which Port of Point Wilson is a first point of entry (section 6). Freight container operators, consignees, forwarders and importers whose goods fall within the defined classes must expect their cargo to be processed through the port as the designated first point of entry.

Waste handlers. The instrument defines waste narrowly as goods intended by the person in charge of the vessel to be disposed of (section 4). Entities handling waste arriving on covered vessels will be affected because waste is specifically listed among the goods for which the port is a first point of entry (section 6).

Biosecurity officials and human biosecurity officers. The instrument requires that proposed changes which affect facilities or amenities for biosecurity officials and human biosecurity officers be notified to the Agriculture Department (section 9(5)(b)). This implies that departmental officers will have an operational presence at Point Wilson Wharf and an interest in port facilities and procedures.

Port customers and service providers. Parties such as stevedores, pilots, tugs, customs brokers, stevedoring contractors and terminal service providers may face indirect operational effects through altered routing, berthing requirements and administrative interactions with the Agriculture Department, because the instrument fixes Point Wilson Wharf as the biosecurity entry point (sections 7 and 8).

The Agriculture Department. The instrument allocates the Agriculture Department as the recipient of written notices and reasonable notice of proposed changes (sections 9(2)-(4)). The Department therefore has an administrative role in receiving and potentially acting upon the notifications required by the instrument.

Excluded classes. Non‑commercial vessels and passenger vessels are excluded from the first point of entry designation (section 5). The instrument therefore does not impose first point of entry routing for those classes of vessel at Port of Point Wilson.

Collective and contractual consequences. Although the instrument itself creates statutory obligations on owners, lessees and responsible operators (section 9), practical compliance will often require contractual adjustments between port owners, terminal operators, vessel operators and freight handlers to ensure the notification duties are met and that vessels and goods are presented to Point Wilson Wharf as required (sections 7 and 8).

The instrument sets out a compact set of statutory duties, primarily administrative and procedural, and identifies the jurisdictional designation rights that attach to Port of Point Wilson.

Duties created by the instrument

• Duty to treat Port of Point Wilson as first point of entry for specified vessels and goods. The instrument itself designates the port for certain vessels and goods (sections 5 and 6). This creates an operational duty on relevant vessel masters, operators and persons handling the specified goods to bring those vessels and goods to the port as a first point of entry, consistent with the Act’s broader obligations (sections 5-8 and the notes to sections 7 and 8 referencing sections 246 and 147 of the Act).

• Duty to bring vessels and goods to designated biosecurity entry point. The instrument specifies Point Wilson Wharf as the biosecurity entry point for the listed vessels and goods (sections 7 and 8). The notes to those sections remind readers that arrival must be brought to a biosecurity entry point as soon as practicable (reference to sections 246 and 147 of the Act). The instrument therefore creates the duty to use the specified physical area for biosecurity processing.

• Notification duty for owners and lessees. If an owner or lessee becomes aware that there has been or will be a change to the business entity operating Port of Point Wilson or a biosecurity entry point, the owner or lessee must notify the Agriculture Department in writing as soon as practicable after becoming aware (sections 9(2)-(3)). The duty applies even where there are multiple owners or lessees because the obligation is phrased so that an owner or a lessee must give notice.

• Pre‑change notice duty for persons/bodies responsible for operations. Where a person or body responsible for operations proposes to make a change listed in section 9(5), that actor must give the Agriculture Department reasonable written notice of the proposed change (section 9(4)). The list in section 9(5) specifies the kinds of procedural and facility changes that trigger the notice obligation.

Form and timing of notices

• Notices must be in writing. Sections 9(2)-(4) require written notice to the Agriculture Department.

• Timing terms are partly undefined. The instrument uses the terms "as soon as practicable" for owners/lessees (sections 9(2)-(3)) and "reasonable notice" for proposed changes (section 9(4)). The instrument does not define those time standards; they are fact‑sensitive and will be interpreted against the statutory text if contested.

Rights and authority

• Regulatory designation right by delegate. The instrument records that it is made by a delegate of the Director of Biosecurity (front matter and section 3). That places the decision to designate the port within the delegated administrative apparatus of the Biosecurity Act 2015.

• Agriculture Department as recipient. The instrument gives the Agriculture Department the role of recipient of written notices under the conditions (sections 9(2)-(4)). The instrument does not, however, create explicit decision rights in the Agriculture Department with respect to approving or vetoing the proposed changes; it sets only notice obligations.

Non‑implied duties and limitations

• No penalties in the instrument. The determination itself does not set out penalties or enforcement measures. It is silent about sanctions for failure to give notice, and so any enforcement consequences would rest on the Biosecurity Act 2015 or other statutory instruments not reproduced here.

• Narrow scope of goods and vessels. The instrument’s duties apply only to the classes of vessels and goods expressly listed (sections 5-8). For goods not listed, the instrument explicitly states the port is not a first point of entry for those goods (section 6, Note 1).

Interplay with other statutory duties

• Cross‑references to Biosecurity Act provisions. The instrument’s notes reference sections 173 and 174 of the Act for matters relating to prohibited and conditionally non‑prohibited goods and sections 147 and 246 for duties to bring goods and vessels to biosecurity entry points as soon as practicable (notes to sections 6-8). Those Act provisions will frame how the duties in this instrument operate in practice.

Who bears compliance costs

• Owners, lessees and operators bear the direct administrative cost of producing and sending notices in writing as required by section 9. Vessel operators and freight stakeholders bear operational costs associated with routing to Point Wilson Wharf as the first point of entry for covered vessels and goods (sections 5-8). Port operators and persons responsible for operations bear potential upgrade or procedural change costs when required to notify the Agriculture Department in advance of proposed changes affecting biosecurity risk (section 9(4)-(5)).

The instrument itself does not establish or specify penalty amounts, enforcement mechanisms or infringement notices. Its enforcement architecture must be understood in relation to the Biosecurity Act 2015, from which the instrument derives its power.

Absence of enforcement provisions in this instrument

• No express penalties. The determination contains no provisions that create offences, specify penalties, or set out civil or administrative consequences for non‑compliance with its notification obligations or other requirements. Sections 5-9 set out duties and designations, but the instrument does not prescribe sanctions.

• Enforcement by reference. Because the instrument is made under subsection 229(1) of the Biosecurity Act 2015 (section 3), enforcement and compliance measures that apply to designations, biosecurity entry points, and obligations to present vessels or goods to biosecurity entry points will be governed by the Act and any regulations, enforcement frameworks and powers contained there. The instrument itself notes other sections of the Act relevant to operational obligations, specifically sections 173, 174, 147 and 246 (notes to sections 6-8). Those referenced sections are not reproduced in the instrument, so readers must consult the Biosecurity Act for the statutory enforcement regime.

Administrative enforcement roles

• Agriculture Department as notice recipient. Sections 9(2)-(4) make the Agriculture Department the recipient of required written notices. The Department will therefore be the administrative point for monitoring compliance with the notification duties. The instrument does not on its face set out what the Department may do with late, inadequate or absent notices.

Potential sources of enforcement or consequence

• Act and regulations. Although the instrument does not create penalties, breaches of duties under the Biosecurity Act 2015, or non‑compliance with directions and powers under that Act with respect to biosecurity entry points and control measures, may attract enforcement action under the Act. The instrument’s front matter and definitions tie it directly to the Act (section 3 and section 4).

• Operational controls. Even where monetary penalties are not prescribed in this instrument, operational consequences may follow discretionary action by biosecurity or other border officials under the Act, including directions to detain, inspect, treat, or refuse entry to goods or vessels. The instrument’s notes point to the statutory duty to bring vessels and goods to entry points as soon as practicable (notes to sections 7 and 8 referencing sections 246 and 147 of the Act); failure to observe such duties may trigger powers under those sections of the Act.

Practical enforcement considerations

• Evidence and proof. Because notice obligations are in writing and directed to the Agriculture Department (sections 9(2)-(4)), proof of compliance will rest on documentary records showing the content and timing of notices. The timing standards "as soon as practicable" and "reasonable notice" will be fact specific and may be contested in disputes.

• Administrative discretion. The instrument gives the Agriculture Department visibility through required notices, but it does not set out the Department’s subsequent decision rights. That creates an administrative environment where the Department may exercise discretion under the Act to address any identified risk or compliance shortfall.

• Coordination with port contracts. Enforcement in practice may be coordinated with contractual remedies between port owners, lessees and operators. The instrument’s duties may be incorporated into lease or service agreements to create reciprocal enforcement mechanisms, but the instrument itself does not compel such contractual steps.

In short, this instrument sets duties and designations but relies on the Biosecurity Act 2015 and executive practice for enforcement and penalties. Parties affected should consult the Act for the full enforcement framework that will apply to failures to comply with the obligations that flow from the instrument.

The determination is an instrument under the Biosecurity Act 2015 and interacts with that Act and, indirectly, with regulatory and contractual law that governs ports, shipping and property. The instrument itself references particular sections of the Act and uses defined terms that import other instruments.

Statutory source and delegation

• Made under Biosecurity Act 2015. The instrument is expressly made under subsection 229(1) of the Biosecurity Act 2015 (section 3). That is the statutory source giving the delegate authority to make a first point of entry determination. Any legal effect of the instrument flows from that delegated power and must be read within the Act’s framework.

Cross‑references within the Biosecurity Act

• Prohibited and conditionally non‑prohibited goods. The note to section 6 refers users to sections 173 and 174 of the Act for matters relating to prohibited goods and conditionally non‑prohibited goods. This indicates that the instrument’s classification of the kinds of goods that may be brought into a first point of entry interacts with the Act’s substantive rules on prohibited or conditional entry for certain goods.

• Duties to present vessels and goods. Notes to sections 7 and 8 reference section 246 (vessels) and section 147 (goods) of the Act regarding the duty to bring arrived vessels and unloaded goods to a biosecurity entry point "as soon as practicable". Those cross‑references signal that the instrument’s operational designation must be read together with the Act’s procedural duties on arrival and unloading.

Imported definitions and other instruments

• Biosecurity Regulation 2016. The instrument borrows the meaning of "non‑commercial vessel" from the Biosecurity Regulation 2016 by saying non‑commercial vessel has the same meaning as in that Regulation (section 4). That imports regulatory definitions into the determination and therefore creates interplay between this instrument and subordinate legislation.

• Definitions within the Act. The instrument defines "Act" to mean the Biosecurity Act 2015 and defines "vessel" by reference to the Act’s definition (section 4). That means the Act’s definitions and interpretive provisions will apply to the instrument’s application and scope.

Contracts, leases and property law

• Owner and lessee duties. Sections 9(2)-(3) create statutory notification duties for owners and lessees. These duties may interact with commercial lease obligations and port operator agreements; port owners and lessees may need to amend or interpret existing contracts to ensure the statutory notification duties are met. The instrument does not itself alter property rights, but its notification conditions will generate operational and contractual consequences.

Maritime and customs law

• Operational overlap. The instrument imposes a biosecurity routing regime for specified vessels and goods. In practice, that will intersect with maritime navigation rules, port operating protocols, customs clearance requirements, and other border control regimes. The instrument does not directly address these other legal regimes, but port operators and vessel masters will have to coordinate compliance across multiple statutory systems.

Administrative law principles

• Reasonableness standards. The instrument uses timing standards of "as soon as practicable" and "reasonable notice" for notification duties (sections 9(2)-(4)). Those standards will be interpreted in light of administrative law principles if disputes arise. The instrument does not define those standards, so the Act and general administrative law will supply interpretive tools.

Limitations and non‑displacement

• Does not override other laws. The instrument does not purport to displace other statutory obligations. Parties must comply both with this determination and with any other applicable statutory, regulatory or contractual duties (for example, obligations under the Biosecurity Act itself, the Biosecurity Regulation 2016, maritime law and any local port bylaws).

In summary, the determination is nested within the Biosecurity Act 2015 and cross‑references particular Act provisions and the Biosecurity Regulation 2016. Its practical effect will be realised in a network of statutory and contractual obligations that govern port operations, vessel arrivals, cargo handling, and the interaction with other border agency regimes.

The instrument contains limited material on its amendment history and the record before the reader is the instrument as originally made.

Original making and commencement

• Made and dated. The instrument is dated 9 December 2025 and signed by a delegate (front matter and signature block). It records the delegate as Josephine Laduzko, Assistant Secretary, Biosecurity Operations Division, Department of Agriculture, Fisheries and Forestry.

• Commencement as made. Section 2 contains a commencement table. Column 2 records that "The whole of this instrument" commences "The day after this instrument is registered. 12 December 2025." The table contains a note that it relates only to the instrument as originally made and "will not be amended to deal with any later amendments of this instrument" (section 2, Note).

Notes about later amendments

• No later amendments recorded. The instrument includes the standard caveat that the commencement table relates only to provisions as originally made and will not be updated to record later amendments. There are no amendment items or schedules in the instrument itself. Therefore, the instrument as presented is the original version and no amendments are recorded within the instrument text.

Forward‑looking references

• Presumption that instrument may be amended. While no amendments are recorded, the instrument’s self‑contained commencement table and the standard note indicate the possibility that the instrument could be amended later under the Act. Any such amendments would be recorded in subsequent registers or consolidated versions external to this instrument.

Practical consequence for users

• Consult register for current version. Users seeking the active legal text should consult the official Federal Register or consolidated instrument lists for any post‑making amendments, since the instrument’s own text does not include later changes and explicitly states that the table will not be updated for later amendments (section 2 Note).

In short, the instrument is presented in its original form with a single commencement entry dated 12 December 2025. No amendment entries are contained within the instrument.

The determination does not contain any litigation history. The text of the instrument makes no reference to judicial decisions, administrative appeals, or prior disputes. There are no cases cited in the instrument and no section records court challenges in its own text.

Implication for practitioners

• No precedents cited. Because the instrument includes no litigation or appeal history, practitioners must rely on the Biosecurity Act 2015, the Biosecurity Regulation 2016 and any subsequent case law interpreting those instruments to assess legal uncertainties. The instrument itself does not identify any judicial guidance on its interpretation.

• Potential for future challenges. Although no litigation history is recorded, the instrument creates duties and uncertain timing standards such as "as soon as practicable" and "reasonable notice" (sections 9(2)-(4)). Those standards commonly generate interpretive disputes which could be subject to administrative review or judicial challenge under the general law. The instrument does not address dispute resolution or review mechanisms beyond the statutory framework of the Act.

• Administrative review routes. The instrument names the Agriculture Department as the recipient of notices and is issued under the Act. If a party sought review of a decision taken by the Department in relation to the instrument’s application, remedies and review rights would arise under the Biosecurity Act 2015 and administrative law, not under the instrument itself.

For now, the instrument records no litigation track record and contains no case law to guide interpretation.

The instrument is short and precise but contains a number of features that create operational uncertainty or could trip up parties who do not read the definitions and timing standards carefully. The following are concrete, source‑grounded points to watch.

Narrow and technical definitions

• Freight container is narrowly defined. The instrument’s definition of freight container requires an enclosed 6‑sided structure that is specifically a 20‑foot or 40‑foot re‑usable container capable of multimodal transfer without unloading (section 4). Non‑standard containers, open‑top containers, swap bodies, or non‑standardized units may fall outside this definition despite being used in practice to carry goods that attract biosecurity control.

• Goods are limited to those under biosecurity control or subject to an exposed goods order. The definition of goods ties back to the Act’s definition but narrows the scope to goods subject to biosecurity control or with an exposed goods order (section 4). This means that many classes of cargo that are not under biosecurity control will not be subject to this port designation.

Subjective and undefined timing standards

• "As soon as practicable" and "reasonable notice". Sections 9(2)-(4) require different temporal standards. For owners and lessees the timing is "as soon as practicable" and for proposed changes by operators the timing is "reasonable notice" (sections 9(2)-(4)). Neither phrase is defined in the instrument, which leaves parties exposed to differing interpretations of timely compliance.

Ambiguity about who is the operator

• Who is "responsible for carrying out operations"? Section 9(4) requires persons or bodies responsible for operations to give reasonable notice of proposed changes, but does not define who that is. Responsibility could fall to a port authority, terminal operator, stevedore, lessee or contracted service provider depending on commercial arrangements. Parties should clarify contractual responsibility to avoid missed notices.

Multiple owners or lessees

• Single owner or lessee must give notice. Sections 9(2)-(3) require that an owner (or, where there is more than one, an owner) or a lessee (or, where there is more than one lessee, a lessee) must give notice. The provision could produce duplicates or gaps where owners do not coordinate. It is not specified which owner must notify in multi‑owner setups, nor is there an obligation to notify jointly.

Scope exclusions

• Non‑commercial and passenger vessels excluded. Section 5 excludes non‑commercial vessels and passenger vessels from the first point of entry designation. Parties expecting the port to be a first point of entry for all vessel types may be surprised.

Waste definition depends on intention

• Waste is defined by the intention of the person in charge of the vessel to dispose of the goods (section 4). That creates a subjective test that could be contested. What is "intended to be disposed of" could vary by cargo owner, agent and master.

No enforcement detail in the instrument

• Instrument is silent about penalties. The instrument sets duties but does not specify enforcement or penalties. Parties cannot rely on the instrument alone to understand consequences of non‑compliance; they must consult the Biosecurity Act 2015 and associated enforcement instruments.

Location specificity and operational effect

• Single biosecurity entry point. Point Wilson Wharf is the sole biosecurity entry point designated for the covered vessels and goods (sections 7-8). Parties with operations elsewhere in the port must ensure that arrival and unloading occur at that wharf for biosecurity processing or risk non‑compliance with the Act’s logics referenced in the instrument’s notes (sections 7-8 notes).

Administrative detail omitted

• No address or procedural form. The instrument requires written notice to the Agriculture Department but does not provide an address, form, or content requirements for the notices (sections 9(2)-(4)). This omission creates practical risk if parties send notices in a manner that the Department considers non‑compliant.

Interaction with other port obligations

• Contractual ripple effects. The notification and operational obligations will interact with leases, service contracts and port operating plans. The instrument does not prescribe how these contractual arrangements should be modified, creating negotiation and transitional costs.

Taken together, these "gotchas" are concrete features of the instrument that create compliance friction, uncertainty about timing and responsibility, and potential for operational disruption unless port owners, operators, and users coordinate their responses to the instrument’s requirements.

Compliance under this instrument is primarily administrative and operational. The following is a practical, source‑grounded checklist of steps and records that parties in the various affected roles should implement to meet the instrument’s requirements and to reduce downstream operational risk.

For port owners and lessees (sections 9(2)-(3))

• Identify the owner and lessee contacts responsible for statutory notice. Where there is more than one owner or lessee, nominate a responsible contact who will give the written notice required by the instrument. Sections 9(2)-(3) require an owner or a lessee to give written notice "as soon as practicable" after becoming aware of a change in the business entity operating the port or a biosecurity entry point.

• Maintain an awareness log. Put in place procedures to capture when an owner or lessee becomes aware of actual or proposed changes to the business entity operating the port or the biosecurity entry point. Record the date and nature of awareness and the timing of any written notice given to the Agriculture Department.

• Prepare written notice templates. Draft standard written notice templates that meet the instrument’s written notice requirement. Although the instrument does not specify required content, include the identity of the notifying party, a description of the change, the date the change occurred or is expected to occur, contact details, and any transitional arrangements.

• Establish delivery and proof procedures. Send notices in a manner that produces clear proof of delivery and content, for example by registered post or recorded electronic transmission with read receipt. Keep copies of notices and delivery confirmation on file.

For persons or bodies responsible for operations (sections 9(4)-(5))

• Map operational responsibilities. Identify who is formally "responsible for carrying out operations at Port of Point Wilson" under commercial contracts. Clarify responsibility in contractual agreements if necessary to ensure the correct party gives "reasonable notice" of proposed changes.

• Define what constitutes "proposed changes". Use the categories in section 9(5) as a checklist to capture which planned changes require notice: procedural changes to biosecurity measures, changes to facilities or amenities used by biosecurity officials, and changes affecting risk identification, communication to officials, or management of contributory factors.

• Provide reasonable written notice. For each proposed change listed in section 9(5), provide the Agriculture Department with reasonable written notice as soon as planning allows. Because "reasonable" is not defined, earlier is safer. The notice should explain the nature of the change, the rationale, expected timing, and any mitigation measures to maintain biosecurity risk controls.

For vessel operators, masters and freight handlers (sections 5-8)

• Route and scheduling. Plan vessel arrivals and cargo discharges so that covered vessels and goods are brought to Point Wilson Wharf, the designated biosecurity entry point, as required by the instrument (sections 7-8). The instrument’s notes reference the Act’s duty to bring arrived vessels and unloaded goods to biosecurity entry points as soon as practicable (notes to sections 7 and 8).

• Identify covered cargo. Use the instrument’s definitions to determine if goods are covered: baggage carried on relevant vessels, freight containers as narrowly defined, and waste as intended for disposal by the person in charge of the vessel (sections 4 and 6). Non‑standard cargo types should be assessed against the instrument’s definitions before relying on an alternate entry point.

• Co‑ordinate with port operator. Confirm with the port operator and terminal staff that Point Wilson Wharf will be available for the required biosecurity processing at the expected arrival time. Ensure berthing plans and port moves reflect the requirement to present at the designated biosecurity entry point.

Operational and infrastructure readiness

• Facilities for biosecurity officials. If the operator proposes changes to facilities or amenities used by biosecurity officials, give the Agriculture Department reasonable notice and supply sufficient information to demonstrate how the facility will continue to support officials’ functions (section 9(5)(b)).

• Procedures for risk identification and communication. If procedural changes may affect identification of biosecurity risks or the ability to inform officials about identified risks, notify the Agriculture Department and supply the updated procedures so that the Department can assess continuity of risk management (sections 9(5)(c)-(d)).

Record keeping and audit trail

• Maintain documentation. Keep contemporaneous records of all notices provided under sections 9(2)-(4), including the date sent, recipient, method of delivery and a copy of the notice content. Retain logs of operational changes, risk assessments and communications with the Agriculture Department.

• Internal escalation triggers. Implement internal triggers to ensure that any proposed change that is within section 9(5) is escalated early to legal and operations teams for drafting and sending of the required "reasonable notice".

Coordination across contracts and regulators

• Review lease and operating agreements. Check port leases, licences and service agreements to ensure the party contractually obliged to give written notice under the instrument is also contractually positioned to do so. Where needed, negotiate amendments or protocols delegating the statutory notice duty to the appropriate party.

• Liaise with other border agencies. Because the instrument functions in the broader border and port regulatory environment, coordinate with customs brokers, border force or other agencies to ensure that presenting vessels and goods at Point Wilson Wharf satisfies other statutory procedures and does not create conflicts.

Practical risk mitigation

• Default to earlier notice. Because "as soon as practicable" and "reasonable notice" are undefined, aim to give notice earlier rather than later. Early notification reduces the risk of a regulatory finding that notice was inadequate.

• Seek clarification. If uncertain whether a proposed change falls within section 9(5), provide a short written notice to the Agriculture Department describing the proposed change and seeking confirmation whether a full "reasonable notice" is required. A conservative approach is to notify and document the request for guidance.

• Keep the Agriculture Department contact current. Because the instrument requires written notices to the Agriculture Department, maintain a current record of departmental contacts and mechanisms for delivery of written notices. If this is not publicly available in the instrument, check departmental guidance portals.

By following these steps grounded in the instrument’s text, affected parties can create a defensible compliance posture, keep an audit trail of required notices, and manage the logistical requirements of presenting vessels and goods to the designated biosecurity entry point at Point Wilson Wharf.
