Fisheries Management (Northern Prawn Fishery Limited-take and Prohibited-take Species) Direction 2021

The Direction rests on a compact set of regulatory concepts that determine who is subject to it, what is prohibited, and how compliance is to be measured.

Primary legal reach. The Direction applies to holders of statutory fishing rights in the Northern Prawn Fishery and to persons acting on their behalf when fishing in the Northern Prawn Fishery area, s 6. The defined term boat means a boat that is nominated on statutory fishing rights for the Northern Prawn Fishery, s 4. The Direction therefore targets activity linked to nominated boats and the holders of statutory fishing rights.

Presumptions about responsibility and timing. Two evidentiary presumptions shape liability and measurement. First, the master of a boat is presumed to have taken all fish present on the boat at any time and to have acted for the holder of the statutory fishing rights for which the boat is nominated, s 4. Second, fish and/or bugs on board are presumed to have been taken during the current trip, or if the boat is not on a trip, the most recent trip, s 4. These presumptions shift practical compliance and enforcement focus onto masters and holders and tie on-board catch to a trip period for limit calculations.

Species categorisation. Species are grouped into: the First Species (Part 1, Schedule 1 , three Lutjanus species), the Second Species (Part 2, Schedule 1 , a list including mackerels, trouts, other snappers and tuna-like species), prohibited-take species (Schedule 2 , a detailed list including barramundi, coral, pearl shell, beche-de-mer, trochus and elasmobranchs among others), and other named categories such as mudcrabs, rock lobsters, bugs, scampi and tuna/tuna-like species, s 7, s 8, Schedules 1 and 2.

Trip-based quantitative controls and size limits. Take limits are trip-based. The base prohibitions in s 8(1) impose per-trip limits that are low for the First and Second Species (1 kg combined of First Species; 10 individuals combined of Second Species), and fixed numerical caps for mudcrabs and rock lobsters. Bugs are subject to minimum carapace width and egg-bearing prohibitions, s 7. The Direction then specifies exemptions to the First Species prohibition that create two seasonal whole-weight thresholds: 550 kg W per trip for trips that end between 1 March and 30 June inclusive, s 9(1), and 50 kg W per trip for trips that end outside that period, s 9(2). Processed catch is to be converted to whole-weight equivalents using explicit conversion formulas, ss 9(1)(c), 9(2)(c).

Processing and conversions. When processed catch is present, the Direction requires whole-weight equivalents to be calculated from gilled and gutted weight (GG), fillet weight (F), or headed and gutted weight (HG) using precise multipliers, ss 9(1)(c), 9(2)(c). These conversion factors directly affect how close a trip comes to the First Weight Limit or Second Weight Limit.

Temporary and species-specific carve-outs. The Direction carves out a specific exemption for longtail tuna (Thunnus tonggol): the prohibition on tuna/tuna-like species does not apply if the only tuna species on board are longtail tuna and no more than 10 longtail tuna are taken per trip, s 9(3). Scampi are prohibited from take for a defined temporal range, s 8(1)(g). The Direction also states that the prohibitions in s 8(1) do not apply where a person is fishing in accordance with another plan of management under the Act, or a State/Territory law in force in relation to the Northern Prawn Fishery area, s 9(4). This creates an explicit exception for alternative regulatory regimes.

Measurement and temporal standard. UTC is specified as the time scale for the Direction’s purposes, s 4. Trip boundaries are defined as the period between departing port and unloading to a mothership or port or other unloading point, s 4. These definitions determine which weight or numerical limit applies to a given catch.

Interaction with other Directions. The Direction contains an instruction to be read consistently with other Directions under the Act, s 4, and it is made under s 41A of the Act, s 3. The text therefore situates itself as one element within the statutory Direction framework, not as a stand-alone regulatory code.

Terminology clarifications. The Direction explicitly defines a set of terms, including bugs (species Thenus parindicus and Thenus australiensis), rock lobster (Panulirus ornatus whole lobster or tail), scampi (families Aristeidae and Nephropidae), and various weight abbreviations W, GG, F and HG, s 4. It also defines the concept trip and states how W is to be computed from processed weights, ss 4 and 9.

Mechanically, these concepts combine to convert on-board product and per-trip activity into objective compliance metrics: size (carapace width), counts (number of individuals per trip), whole-weight measures (with conversion factors for processing), species inclusion/exclusion via schedules, and trip timing (for seasonal threshold application), ss 4, 7-9, Schedules 1-2.

The Direction identifies a narrow but operationally significant cohort of persons and vessels as subject to its requirements.

Primary regulated persons. The Direction applies to holders of statutory fishing rights in the Northern Prawn Fishery, and to persons acting on behalf of such holders, when they are fishing in the Northern Prawn Fishery area, s 6. The defined term holder references the Act’s definitions, s 4. Because boat is defined as a boat nominated on statutory fishing rights for the Northern Prawn Fishery, s 4, the instrument directly targets activity on nominated boats and the legal relationships that attach those boats to statutory fishing rights.

Masters. The Direction places a legal presumption on masters of boats. For the Direction’s purposes, the master is presumed to have taken all fish present on the boat at any given time and to have acted on behalf of the holder of the statutory fishing rights for which the boat is nominated, s 4. This presumption makes masters a central locus of compliance attention: masters’ actions and the catch physically on board are imputed to holders, and masters are treated as acting for holders for liability and accounting purposes.

Processors and those altering product form. The Direction treats processed catch differently by requiring conversions to whole-weight equivalents, ss 9(1)(c) and 9(2)(c). Persons who process catch on board, prior to unloading, thus affect the computation of whether the First Weight Limit or Second Weight Limit has been exceeded. Processors aboard a boat, or arrangements that alter the product before landing, will therefore be relevant to compliance calculations.

Operators of motherships and unloading points. The Direction defines trip as the period between departing port and unloading of a catch, or part of a catch, to a mothership or port or other unloading point, s 4. Because limits apply per trip, operators and arrangements that result in partial unloading to motherships can affect how limits are applied and monitored. The person who records or controls the unloading event will be relevant in enforcement or compliance assessment.

Fishers targeting particular species. Fishers who target species listed in Schedules 1 and 2 are directly affected. Schedule 1 Part 1 lists three Lutjanus species as First Species; Part 2 lists several species and families including longtail tuna as Second Species. Schedule 2 lists prohibited-take species such as barramundi, pearl shell, beche-de-mer, trochus and elasmobranchs, s 8 and Schedules 1-2. Fishers who encounter these species must either avoid taking them or comply with the strict quantity, size and other prohibitions.

Fishers seeking to rely on alternative management regimes. Section 9(4) provides that the prohibitions in s 8(1) do not apply to a person if they are fishing in accordance with another plan of management under the Act, or a State or Territory law in force in relation to the Northern Prawn Fishery area. This affects persons operating under different regulatory instruments; they may be exempt where a conflicting plan of management or State/Territory law applies to the activity.

Those handling bugs. The Direction’s bug prohibitions are precise. Bugs are defined as Thenus parindicus and Thenus australiensis, and the Direction bars taking bugs with carapace width less than 60 mm and egg-bearing female bugs, the latter explicitly including bugs that have been scrubbed to remove eggs or chemically de-egg’d, s 4 and s 7. Persons who capture, handle or process bugs must therefore ensure compliance at capture stage and after any on-board processing.

Time-sensitive actors. The temporary prohibition on scampi, s 8(1)(g), applies for a defined period , from commencement until 2230 UTC on 30 November 2022 , so persons active in the fishery during that window are affected differently from those operating outside it.

Administrative and enforcement actors. Although the Direction is made under the Act, it does not itself set out enforcement penalties. The parties responsible for monitoring, compliance and enforcement will therefore be those who exercise powers under the Act and other Directions, s 3 and s 4. The Direction’s design presumes enforcement capability to measure weights, counts, and species identity against the specified schedules and conversions.

In sum, the Direction affects holders of statutory fishing rights and persons acting for them when fishing in the Northern Prawn Fishery area, the masters of nominated boats (by presumption), processors and those handling product form on board, operators involved in unloading to motherships or ports, and fishers whose activities intersect the listed species and temporal limits. The instrument’s definitions and presumptions make masters and nominated boats the operational focal point for compliance and for attributing catch to holders, ss 4, 6-9.

The Direction creates a set of obligations and a narrow set of permissive exceptions for regulated persons. The instrument does not, in the provided text, create affirmative rights to any particular catch beyond the permitted exemptions; it mainly imposes prohibitions and conversion rules.

Key duties

• Do not take undersize bugs. Fishing in the Northern Prawn Fishery is not to be engaged in for bugs with a carapace width less than 60 mm, s 7(1)(a). This is an absolute size limit for the articulated bug species, s 4 and s 7.
• Do not take egg-bearing female bugs. The Direction prohibits taking egg-bearing female bugs, with the definition of egg-bearing female bugs including those scrubbed to remove eggs and those with eggs chemically removed, s 7(1)(b) and s 4.
• Respect per-trip quantity limits. The default prohibitions in s 8(1) make it an offence under the Direction to fish for: First Species in excess of a combined catch of one kilogram per trip, s 8(1)(a); Second Species in excess of a combined catch of ten individual fish per trip, s 8(1)(b); mudcrabs in excess of ten individuals per trip, s 8(1)(c); rock lobsters in excess of six individuals per trip, s 8(1)(d); and species named in Schedule 2, s 8(1)(e), as well as tuna or tuna-like species, s 8(1)(f), subject to the exemptions in s 9.
• Observe scampi prohibition during the specified period. The Direction prohibits taking scampi for the period from commencement to 2230 UTC on 30 November 2022, s 8(1)(g).
• Apply conversion factors for processed catch. Where the First Weight Limit or any part of it has been processed, the master/holder must determine the whole-weight equivalent using explicit formulas W = GG x 1.1, W = F x 2.6, W = HG x 1.4, ss 9(1)(c), 9(2)(c). These conversion duties apply to both the 550 kg and 50 kg whole-weight thresholds.
• Ensure trip-recording that determines which seasonal threshold applies. The exemptions in s 9 make the ending point of a trip determinative: trips ending in the period 1 March to 30 June are eligible for the First Weight Limit of 550 kg W, s 9(1); trips ending outside that period get a 50 kg W limit, s 9(2). The Direction defines trip as between departing port and unloading, s 4, making accurate trip boundaries essential to apply the correct limit.
• Ensure species identification against Schedules. The Direction’s prohibitions and limits are species-specific. The master/holder must be able to identify species present on board against the lists in Schedules 1 and 2 in order to determine whether prohibited-take or restricted species are present, ss 8 and Schedules 1-2.
• Comply with the presumption rule. For the Direction’s purposes the master is presumed to have taken all fish present on board and to be acting for the holder, s 4. Holders therefore must ensure their masters operate within the Direction’s limits, and masters must manage on-board catch accordingly.

Permissive exceptions and rights

• First Species seasonal weight exemption. The prohibition in s 8(1)(a) does not apply if the trip ends during 1 March-30 June and no more than 550 kg W of First Species are taken per trip, s 9(1). This creates a temporary per-trip right to take up to 550 kg W of First Species in that seasonal window, provided conversions for processing are applied.
• First Species out-of-season exemption. Outside the 1 March-30 June window, the instrument permits up to 50 kg W of First Species per trip, s 9(2).
• Longtail tuna exception. The prohibition on tuna/tuna-like species does not apply if the only tuna on board are longtail tuna and no more than ten of them are taken per trip, s 9(3). That creates a narrowly defined permission to take limited numbers of a specific tuna species.
• Exemption where other management applies. The prohibitions in s 8(1) do not apply to a person if the person is fishing in accordance with another plan of management in force under the Act, or a State or Territory law that applies in the Northern Prawn Fishery area, s 9(4). This preserves the primacy of other, applicable plans of management and State/Territory regulation where they apply.

Duties of conversion and measurement. The Direction’s formulas for converting processed weights to whole-weight equivalents, ss 9(1)(c), 9(2)(c), are technical obligations that require accurate measurement of GG, F or HG and application of the stated multipliers. The Direction also specifies that UTC is the time standard for its purposes, s 4, and that W, GG, F and HG are measured in kilograms, s 4. These are measurement duties that require technical accuracy and recordkeeping.

Absence of penalty text within the Direction. The Direction, as provided, does not set out specific penalties, fines or enforcement procedures. It is made under s 41A of the Act, s 3, and is to be read with other Directions, s 4, which implies that enforcement and sanctioning rest with the Act and other Directions rather than with the content of this instrument. Duty-holders should therefore be aware that breaches will be addressed under the Act and the broader regulatory regime.

In short, the Direction imposes per-trip and size limits, requires specific conversion and measurement practices where processing occurs, confers narrowly defined seasonal and species-specific permissions, and imputes responsibility for on-board catch to masters and holders, ss 4, 7-9, Schedules 1-2.

The Direction as printed contains no express penalty clauses or procedural enforcement provisions. The instrument is made under section 41A of the Fisheries Management Act 1991, s 3, and instructs that it is to be read consistently with other Directions made under the Act, s 4. Therefore, enforcement authority, sanctioning powers, inspection powers, and penalty regimes are not located in the Direction itself but are to be found in the Act and other Directions or subordinate instruments that govern enforcement in the Northern Prawn Fishery.

What the Direction does specify that bears on enforcement

• Presumptions that facilitate attribution. The Direction contains presumptions designed to simplify attribution of catch for compliance purposes: the master of a boat is presumed at any time to have taken all fish present on the boat and to have acted on behalf of the holder nominated to that boat, s 4. Also, fish and/or bugs on board are presumed to have been taken during the current trip, or if the boat is not on a trip, during the most recent trip, s 4. These presumptions narrow factual disputes about timing and responsibility and provide a clear evidential starting point for enforcement agencies when assessing alleged breaches.
• Objective measurement rules. The Direction provides specific, objective conversion factors to determine whole-weight equivalents from processed product, ss 9(1)(c), 9(2)(c). These make it possible to enforce the First Weight Limit and Second Weight Limit through standardised calculations rather than through contested estimations of processing loss. The use of UTC as the time standard, s 4, creates a uniform temporal baseline for determining whether a trip ended within the 1 March-30 June window, ss 9(1)-9(2).
• Clear per-trip thresholds and species lists. The Direction establishes precise per-trip thresholds (1 kg First Species default, 10 individuals Second Species default, 10 mudcrabs, 6 rock lobsters, and explicit prohibitions for Schedule 2 species), ss 8-9, Schedules 1-2. Such clear numerical limits enable straightforward comparison between observed catch and legal limits.

Implications for enforcement practice

• Evidence and inspection needs. Enforcement entities will need the ability to identify species on board against Schedule lists, measure carapace width for bugs, count individuals for numerical limits, and weigh or measure processed product consistent with GG, F or HG to apply conversion factors. The Direction presumes that such inspection, measurement and species identification are feasible and that enforcement authorities operate under powers in the Act or other Directions to make such determinations, s 4.
• Allocation of liability. Because the master is presumed to act for the holder and to have taken all fish on board, s 4, enforcement actions can proceed against masters and holders based on presence of catch alone unless rebutted under the Act or other Directions. That presumption shifts the enforcement burden of proving which entity took the catch towards regulated persons who will need to keep contemporaneous records to rebut the presumption if appropriate.
• Temporal enforcement complexity. The seasonal exemption for the First Species , 550 kg W for trips ending between 1 March and 30 June, s 9(1), and 50 kg W for other times of year, s 9(2) , makes enforcement dependent on accurate records of trip start and end times, tied to UTC, s 4. Disputes about trip end events (for example, partial unloading to a mothership versus final landing) could be material.

Limitations and gaps in the Direction’s enforcement detail

• No penalties specified in the Direction. The absence of penalty provisions or explicit enforcement mechanisms in the text provided means that the legal consequences for contraventions are not set out here. Enforcement and sanctions therefore default to the Act and associated directions, s 3 and s 4.
• Reliance on other instruments. The Direction’s command that it be read consistently with other Directions under the Act, s 4, implies that enforcement powers, evidentiary rules, administrative procedures and appeal mechanisms are contained elsewhere. Regulated parties must therefore consult the Act and related Directions to understand the procedural and penalty landscape.

To summarise, the Direction establishes clear, enforceable-sounding presumptions, objective measurement and conversion rules, and fixed per-trip limits that facilitate enforcement, but it does not itself set out penalty provisions or enforcement procedures. Enforcement will proceed under the Act and other Directions and will rely on the Direction’s presumptions and conversion rules as evidential tools, ss 3-4, 7-9, Schedules 1-2.

The Direction expressly situates itself within the broader statutory framework and preserves hierarchical and parallel regulatory relationships. The text also creates explicit exceptions where other instruments or laws apply, and it instructs readers about consistent reading with other Directions.

Made under the Act. The Direction is made under section 41A of the Fisheries Management Act 1991, s 3. That identifies the Act as its enabling statute and indicates that the Direction is subordinate legislation derived from powers in the Act. The Direction should therefore be interpreted and applied within the constraints and structure of the enabling Act.

Consistency with other Directions. The text requires that the Direction be read consistently with other Directions under the Act, s 4. That instruction signals that this instrument is one element of a network of Directions governing the fishery. Where other Directions provide procedures, enforcement mechanisms, or differing substantive rules applicable to the same boats or trips, the Direction requires consistency, and s 9(4) recognises exceptions where other management instruments govern particular activity.

Saving for other plans of management and State/Territory laws. Section 9(4) provides that the prohibitions in s 8(1) do not apply if the person is fishing in accordance with another plan of management in force under the Act, or a law of a State or Territory that is in force in relation to the Northern Prawn Fishery area. This clause creates an explicit legal interaction rule: where a person is covered by a different plan of management under the Act, or by a State/Territory law that applies to the fishery area, the Direction’s s 8(1) prohibitions will not apply to that person. This means persons operating under alternative management regimes must determine which instrument governs their activity and may rely on those other instruments rather than this Direction for permissive or restrictive rules.

Relationship to plans of management. Several definitions used in the Direction are noted as being in the definitions section of the Act and in the interpretation section of the Northern Prawn Fishery Management Plan 1995, s 4. The Direction therefore references the plan of management framework and may interact with the Northern Prawn Fishery Management Plan 1995 on matters of meaning and scope, as specified in s 4.

Repeal of prior instrument(s). Section 5(1) states that the instrument specified in Schedule 3 is repealed as set out in that Schedule. Although the Schedule 3 text is not provided here, that provision shows the Direction can displace earlier subordinate instruments, and readers must consult Schedule 3 to see which earlier instrument(s) are affected. Section 5(2) also declares that Schedules 1 and 2 have effect according to their terms, tying the species lists to the Direction’s application.

Operative definitions and statutory cross-references. Several key expressions are explicitly noted as defined in the Act’s definitions or in the Northern Prawn Fishery Management Plan 1995, s 4, including boat, fish, fishing, holder, master, plan of management, processing, statutory fishing right and take, and terms used in the plan of management such as Northern Prawn Fishery area. That cross-referencing means that matters such as the legal meaning of “holder” or “statutory fishing right” are governed by the Act and the Plan, not solely by this Direction.

Implications for regulated persons

• Determine applicable instrument hierarchy. A person fishing in the Northern Prawn Fishery needs to establish whether they fall under this Direction, another plan of management under the Act, or a State/Territory law that applies to their activity, because s 9(4) displaces s 8(1) prohibitions where another applicable plan or law applies.
• Consult the Act and relevant Directions for enforcement detail. Because the Direction does not itself state enforcement powers, appeals, or penalties, regulated persons must consult the Act and other Directions for those details; the Direction’s instruction to be read consistently with other Directions reinforces this need, s 4.
• Harmonise species and measurement definitions. Species identification, trip definitions and processing terminology are drawn from both the Act and the Northern Prawn Fishery Management Plan 1995, s 4, so operators must consult those instruments for authoritative definitions that may affect the Direction’s application.

In summary, the Direction is subordinate to the Fisheries Management Act 1991, must be read with other Directions, and expressly yields to other plans of management under the Act and relevant State/Territory laws where those instruments apply, ss 3-4, 9(4). Regulated persons must therefore treat this Direction as part of a matrix of instruments governing activity in the Northern Prawn Fishery area.

The Direction is titled the Fisheries Management (Northern Prawn Fishery Limited-take and Prohibited-take Species) Direction 2021, s 1. The text provided does not record any subsequent amendments to this instrument within its body. It does, however, include a provision, s 5(1), that repeals "the instrument that is specified in Schedule 3 to this instrument" as set out in that Schedule. The content of Schedule 3 is not included in the material supplied here, so the identity of the repealed instrument(s) and the scope of repeal must be confirmed by consulting Schedule 3 in the full instrument.

Elements to note in the instrument that bear on amendment and temporal effect

• Commencement and temporal provisions. The Direction contains a time-limited prohibition on scampi in s 8(1)(g): the prohibition applies in the period commencing on the day this instrument commences and ending at 2230 hours UTC on 30 November 2022. That is a fixed-date temporal provision that creates an expiry point for that particular species prohibition, and it ties the operative date to the instrument’s commencement.
• Seasonal exemption tied to calendar dates. The First Species exemptions in s 9(1) are explicitly seasonal, applying to trips that end during the period beginning on 1 March and ending on 30 June in a year during the period of application of the Direction. That creates annual, recurring seasonal applicability rather than a single-time amendment, but the Direction’s overall duration or expiry is not stated in the provided text.
• Repeal of prior instrument(s). Section 5(1) signals a structural amendment by repealing an instrument specified in Schedule 3, evidence that the 2021 Direction replaced or updated prior subordinate legislation. The specifics are in Schedule 3, which must be consulted to see which prior instrument(s) were repealed and whether repeal was partial or complete.
• Schedules operative on commencement. Section 5(2) states that Schedules 1 and 2 have effect according to their terms. In practice, any later amendment to Schedules 1 or 2 would change the species lists to which the per-trip limits and prohibitions apply.

What the instrument does not state about amendments

• No in-text schedule of amendments. The provided text does not include an amendment schedule or a history table documenting dates of any amendments after 2021. It therefore does not record whether, and on what dates, later adjustments were made to the thresholds, species lists or definitions.
• No sunset for the Direction as a whole. Except for the scampi prohibition’s end date, the Direction does not specify an expiry or sunset for itself in the provided text. The duration of the Direction and any future amendments would therefore be found in external amendment instruments or the legislative register.

Practical steps for readers seeking amendment history

• Consult Schedule 3 in the full instrument to identify repealed instruments and the nature of change effected by the 2021 Direction, s 5(1).
• Check the legislative register, the Act’s delegated legislation registers and any consolidated version of the Direction for later amending instruments or revocations. The Direction’s title and year aid that search, s 1, but those sources are external to this text.
• Verify whether the scampi prohibition end date (2230 UTC on 30 November 2022) expired as scheduled, and whether any new instrument extended, reintroduced, or replaced the scampi rule; the Direction itself contains the temporal clause but no post-expiry continuation provision, s 8(1)(g).

In short, the Direction’s internal amendment record is limited: it is a 2021 instrument; it repeals an instrument specified in Schedule 3, s 5(1); and it contains at least one fixed-date temporal prohibition for scampi, s 8(1)(g). For a complete amendment history beyond these elements, the full instrument’s schedules and external legislative records must be consulted.

The instrument as provided contains no references to litigation, judicial determinations, declaratory actions or case law. It does not cite any judicial decisions, and no proceedings are recorded in the text. Because the Direction is made under section 41A of the Fisheries Management Act 1991, s 3, any enforcement, prosecution, or judicial review in respect of actions taken under or in reliance on the Direction would be initiated under the Act and conducted in the courts or tribunals that the Act designates, but those procedural paths and any existing case law are not set out in this instrument.

What the Direction’s text does and does not disclose about litigation risk

• Presumptions that may inform admissible inferences. The Direction’s evidential presumptions , that the master is presumed to have taken all fish present on the boat at any time and to have acted on behalf of the holder, and that fish on board are presumed to have been taken during the current trip or most recent trip, s 4 , will likely be central in any enforcement proceedings. Those presumptions make certain facts easier for regulators to rely upon, and they set the starting point for disputed factual questions. The Direction itself does not address how those presumptions can be rebutted in litigation; that matter will be governed by the evidentiary and procedural rules of the Act and applicable courts.
• Conversion rules and disputes. The conversion factors for processed product (W = GG x 1.1; W = F x 2.6; W = HG x 1.4), ss 9(1)(c), 9(2)(c), are precise. Any litigation over alleged breaches of the First or Second Weight Limits would likely focus on measurements, application of those conversion multipliers, and accuracy of weighing and processing records. The Direction does not prescribe measurement methodology beyond the conversion formulas, so procedural disputes about measurement technique would be adjudicated under the Act or by an evidence-led process in court.
• No recorded cases within the instrument. Because the instrument text contains no litigation history or references to cases, there is no in‑text precedent to cite about the Direction’s interpretation or enforcement in judicial settings.

How readers should proceed to discover litigation history

• Search court and tribunal records for any proceedings alleging contravention of this Direction or enforcement actions taken under the Fisheries Management Act 1991 that reference this Direction. The Direction’s title and year identify it as the relevant instrument for searches.
• Review administrative decisions, if any, under the Act and any published prosecutorial decisions that invoke this Direction’s provisions.
• Examine the Act and other Directions for procedural steps relevant to judicial review, administrative review or appeals, since those processes will govern how decisions under this Direction are contested and ultimately litigated.

In summary, the Direction does not record any litigation history. The presumptions and conversion rules in the Direction set out factual and measurement starting points that would be relevant in any enforcement litigation, but procedural and evidentiary rules, and any existing case law, will be found in the Act, other Directions and external case law records rather than in the Direction itself, ss 3-4, 9(1)(c), 9(2)(c).

The Direction contains several features that are easy to overlook but that materially affect compliance, enforcement and practical fishing behaviour. These are concrete operational points grounded in the instrument text.

Presumption of master’s actions and imputation to holder (s 4). For the Direction’s purposes, the master is presumed to have taken all fish on board and to have been acting for the holder of the statutory fishing right for which the boat is nominated. This presumption means that catch discovered on a nominated boat will be imputed to the master and the holder unless rebutted under the Act or other Directions. It places practical responsibility on holders to control masters’ behaviour and on masters to manage on-board catch, because discovery of prohibited or excess catch on board will be attributed to them.

Trip definition determines which limit applies (s 4, ss 8-9). The Direction defines trip as the period between departing port and unloading of a catch, or part of a catch, to a mothership or port or any other point where catch is unloaded, s 4. Because the First Species weight limit is seasonal based on the trip end date , 1 March-30 June eligible for 550 kg W, s 9(1); other times 50 kg W, s 9(2) , operators who partially unload to motherships, or who make intermediate unloading events, may change which limit applies. Accurate recording and understanding of what constitutes unloading is therefore critical.

Processed catch conversion obligations (ss 9(1)(c), 9(2)(c)). If any part of the First Weight Limit has been processed, whole-weight equivalents must be calculated using the conversion factors provided. Failure to apply or misapplying these conversion rates will affect whether a trip exceeds the permitted weight for First Species. Operators need to ensure that measurements of GG, F or HG are accurate and formula application is consistent.

Egg removal does not circumvent the egg-bearing female bugs prohibition (s 4, s 7). The definition of egg-bearing female bugs expressly includes bugs that have been scrubbed to remove eggs and those that had eggs removed using chemicals. That means attempts to remove eggs by cleaning or chemical treatment do not render a formerly egg-bearing female lawful to possess under this Direction. Practitioners must therefore treat any female bugs that were carrying eggs at capture as prohibited, regardless of subsequent on-board cleaning.

Tight numerical per-trip limits (s 8). The default per-trip limits in s 8(1) are low for certain species: 1 kg combined for First Species as a default, and 10 individuals for Second Species. These low thresholds, especially the 1 kg default for First Species, mean that unless the operator qualifies for the seasonal exemptions in s 9, almost any take of First Species will need careful accounting since the default is very restrictive.

Longtail tuna carve-out is narrowly framed (s 9(3)). The tuna/tuna-like prohibition in s 8(1)(f) is only relaxed where the only tuna and tuna-like species on board are longtail tuna (Thunnus tonggol) and no more than ten are taken per trip. If any other tuna species is present, the exemption does not apply. Operators must therefore be confident of species identification when relying on this exception.

Scampi prohibition is time-limited (s 8(1)(g)). The prohibition on scampi runs only from commencement to 2230 UTC on 30 November 2022. After that time the prohibition, as written, would expire. Persons operating near that window should verify whether subsequent instruments extended or replaced this rule, because the present text contains a single fixed end date and no extension mechanism.

Species list idiosyncrasies in Schedules. Schedule 2 includes “Coral” with no scientific name provided, and in other entries the scientific names are formatted in a way that may complicate identification (for example Queenfish entry with two scientific names separated by a semicolon). Schedule 1 Part 2 uses family names for groups such as Serranidae and Lethrinidae. These presentation features could create ambiguity in species identification and enforcement unless clarified by relevant biological or regulatory guidance. Practitioners should be aware that the Direction ties obligations to named lists, but the lists’ format requires careful reading.

Conversion factors rely on measure types (ss 9(1)(c), 9(2)(c)). The conversion formulas require measurement in GG, F or HG. If enforcement or on-board practice measures different weight types or uses different rounding conventions, disputes could arise about whether the whole-weight equivalent calculation was performed correctly.

Exemption where other plans or State/Territory laws apply (s 9(4)). The Direction cedes application of s 8(1) prohibitions where another plan of management under the Act or a State/Territory law applies to the fishing activity. Operators must confirm which legal regime governs their activity, because the existence of an alternative applicable law can nullify the Direction’s prohibitions for a particular person.

UTC and time standardisation (s 4). The Direction uses Coordinated Universal Time as its time standard, s 4, and equates it to mean solar time at the prime meridian. Trip end dates and the scampi prohibition end time are measured in UTC. Operators who record in local time must convert accurately to UTC to determine compliance with seasonal and time‑limited provisions.

No penalties in the text supplied (s 3, s 4). The Direction does not set out penalties; enforcement falls back to the Act and other Directions. That means that while the Direction sets substantive limits, the precise legal consequences of breaches are to be found in the Act, and operators must consult it and other Directions for procedural and penalty specifics.

In combination, these “gotchas” create operational and evidentiary risks: imputation of catch to masters and holders, narrow numerical thresholds, conversion and processing measurement rules, temporal triggers tied to trip end, and potential ambiguity in species lists. Each is grounded in the Direction’s explicit text, ss 4, 7-9, Schedules 1-2.

Compliance with this Direction requires operational adjustments, recordkeeping, measurement practices and species identification procedures that align with the Direction’s prescriptive thresholds, definitions and presumptions. Below are practical steps and the statutory bases for them.

1. Confirm applicability to the boat and persons

• Ensure the boat is nominated on the statutory fishing rights for the Northern Prawn Fishery if it is to operate under those rights, since boat is defined as such, s 4.
• Verify whether the person fishing is acting under this Direction or under another plan of management under the Act or a State/Territory law that applies; s 9(4) exempts persons fishing under other applicable plans or laws from s 8(1) prohibitions.

2. Record trip boundaries accurately and in UTC

• Record trip departure and unloading times and locations precisely in UTC, the time standard for the Direction, s 4.
• Treat trip end as the unloading event to a mothership, port or other unloading point, s 4, because the seasonal First Species threshold depends on the trip ending date, ss 9(1)-9(2).

3. Control on-board catch to meet per-trip limits

• Unless a seasonal exemption applies, ensure combined First Species does not exceed the default 1 kg per trip, s 8(1)(a), and combined Second Species does not exceed 10 individual fish per trip, s 8(1)(b).
• For mudcrabs and rock lobsters, ensure no more than 10 and 6 individuals per trip respectively, s 8(1)(c)-(d).
• Avoid taking any species listed in Schedule 2, which are prohibited-take species, s 8(1)(e).

4. Comply with bug size and egg-bearing prohibitions

• Measure carapace width at its widest point; do not take bugs with carapace width less than 60 mm, s 7(1)(a). Maintain measuring tools and protocols to document compliance.
• Do not take egg-bearing female bugs. Treat as prohibited any female bug that was egg-bearing at the time of capture, including those scrubbed or chemically treated to remove eggs, s 7(1)(b) and s 4.

5. Apply seasonal First Species weight exemptions correctly

• For trips ending between 1 March and 30 June inclusive, the First Species whole-weight limit per trip is 550 kg W, s 9(1).
• For trips ending outside that period, the First Species whole-weight limit per trip is 50 kg W, s 9(2).
• When processing has occurred, calculate whole-weight equivalent using the conversion factors: W = GG x 1.1; W = F x 2.6; W = HG x 1.4, ss 9(1)(c), 9(2)(c). Keep accurate measurements in GG, F or HG as applicable.

6. Handle processed product with clear measurement and documentation

• If any First Species has been processed on board, measure GG, F or HG to the accuracy required by the operational or enforcement context and apply the specified multiplier to obtain whole-weight equivalents, ss 9(1)(c), 9(2)(c).
• Retain records of processing steps, weights, dates and times that link processed product to the specific trip and unloading event in UTC, s 4.

7. Use species identification protocols aligned with Schedules

• Ensure that crew or on-board observers can identify species listed in Schedule 1 and Schedule 2. The schedules include common and scientific names and family names for groups, Schedules 1-2.
• Where Schedule entries use family names (for example Serranidae, Lethrinidae) or multiple scientific names, adopt conservative identification procedures that avoid mistakenly classifying a prohibited species as a permitted one.

8. Apply the longtail tuna exemption only where strictly permitted

• The general prohibition on tuna and tuna-like species, s 8(1)(f), is subject to the exemption in s 9(3) only if the only tuna/tuna-like species on board are longtail tuna (Thunnus tonggol) and no more than ten longtail tuna are taken per trip. If any other tuna species is present, the exemption does not apply.

9. Observe the scampi temporal prohibition

• Do not take scampi in the period from the Direction’s commencement until 2230 UTC on 30 November 2022, s 8(1)(g). After that, check whether a new instrument alters this restriction.

10. Maintain records to rebut presumptions if necessary

• Because the master is presumed to have taken all fish on board and to have been acting for the holder, s 4, holders and masters should maintain contemporaneous records (logbooks, witness statements, unloading receipts, chain-of-custody documentation) that could rebut the presumption if there is a legitimate basis to do so.
• Record instances of catch found on board that were not taken during the current trip and explain circumstances where possible, since fish on board are presumed to have been taken during the current trip or, if the boat is not on a trip, the most recent trip, s 4.

11. Coordinate unloading events and mothership transfers

• Because trip end for the purpose of the seasonal thresholds depends on unloading, s 4 and ss 9(1)-9(2), plan unloading to ensure the trip falls within the desired seasonal bracket if relying on the higher seasonal weight limit. Maintain documentation of mothership transfers, unloading times and locations.

12. Consult other instruments for enforcement and penalties

• The Direction does not specify penalties; they arise under the Act and other Directions, s 3 and s 4. Maintain compliance with those instruments as well and obtain legal or regulatory advice on procedural and penalty exposure under the Fisheries Management Act 1991.

13. Update procedures in response to Schedule or instrument changes

• Monitor for amendments to Schedules 1-2 and any subsequent Directions that repeal, replace or modify this instrument. Section 5(1) shows this instrument repealed an earlier instrument specified in Schedule 3; changes can therefore occur by delegated legislation, s 5(1).

By implementing the above operational steps, maintaining accurate measurement and time records in UTC, applying conversion formulas for processed product, and ensuring species identification aligned to the Schedules, masters and holders can align their practices with the Direction’s requirements. The statutory bases for each step are s 4 (definitions and presumptions), s 7 (bugs prohibitions), s 8 (per-trip prohibitions), s 9 (exemptions and conversions) and Schedules 1-2 (species lists).
