The central concept is the seaward limit, defined separately for each watercourse in Schedule 1. This is the point beyond which the watercourse is deemed to be no longer inland waters for the purposes of the Inland Fisheries Act 1995. The Order uses four principal methods to fix these limits. The first is a grid reference drawn from the Universal Grid Reference System used in Tasmania. For example, the Arthur River’s seaward limit is simply “the mouth of that river at grid reference 303452/5452424”. The second method is an imaginary straight line across the watercourse, often between two fixed points. The Huon River limit is an imaginary line between a white post on Castle Forbes Bay and another white post on the opposite bank. The third method is a bridge crossing, usually defined as “the downstream side of the bridge carrying the [road] across that river”. The Cam River’s limit is the downstream side of the bridge carrying the A2 road across it. The fourth method is a natural or artificial feature such as a point, a bend, a wharf, a boat ramp, or the upper end of a reach. The Davey River limit is “the upper end of Brooks Reach on that river at grid reference 412872/5217634”. Some limits combine methods, such as the Esperance River’s limit, which is an imaginary straight line defined by two grid references. The Order also uses the concept of high-water mark indirectly; for the Great Forester River the limit is described as a point on Adams Cut “being a continuation of the high-water mark on Waterhouse Beach”. The interpretation clause defines two key terms: Act means the Inland Fisheries Act 1995, and grid reference means the grid reference taken from the Universal Grid Reference System used in Tasmania. The clause also provides that where a road is referred to by a capital letter and a numeral, that reference is to the road so identified in the road classification used in Tasmania. This is important because many bridges are identified by the road they carry, and road classifications can change. The Order itself does not define “white post” or explain who erected them or maintains them, which creates an evidentiary issue if a post is missing or moved. The concept of “downstream side” of a bridge is also not defined and may be ambiguous if the bridge is not perpendicular to the flow or if the flow direction changes. The Order relies on the primary Act for the substantive regulatory implications of these boundaries. Understanding that the seaward limit is a jurisdictional line, not an ecological or hydrological or property boundary, is essential.

The Order directly affects any person who fishes or proposes to fish in any of the 75 listed watercourses. This includes recreational fishers, licensed commercial fishers, charter boat operators, and anyone gathering marine or freshwater organisms for any purpose under the Inland Fisheries Act 1995. Because the Order defines where the Act ceases to apply, it determines which fishing licence is required. A person fishing upstream of the seaward limit is fishing in inland waters and must hold an inland fisheries licence and comply with inland fishing rules. A person fishing downstream of that limit is in tidal waters and must hold a coastal or scalefish licence under the Living Marine Resources Management Act 1995 and comply with that Act’s rules, unless a specific exemption applies. The demarcation also affects the jurisdiction of the Inland Fisheries Service versus the Department of Primary Industries and Regional Development (or its equivalent). Enforcement officers must know which set of rules applies at any given location. The Order also affects landowners whose properties abut listed watercourses. A landowner who constructs a structure, extracts gravel, or alters a watercourse may need different approvals depending on whether the activity is above or below the seaward limit. The definition can affect the application of the Water Management Act 1999 and the Land Use Planning and Approvals Act 1993, because those Acts sometimes use the seaward limit as a boundary for various regulatory zones. Commercial operators such as aquaculture lease holders, fish processors, and tourism operators who conduct guided fishing trips must ensure they do not inadvertently breach the jurisdictional boundary. The Order also affects government agencies, particularly the Inland Fisheries Service and the Tasmanian Planning Commission, which must apply the correct legal framework when assessing applications for water-related developments or activities. The revocation of the 1996 Order means that anyone who relied on the old boundaries must recalibrate their understanding to the 2004 definitions, and to the 2010 amendment to Schedule 1. The Order also imposes a burden on the court system, because any prosecution for fishing without the correct licence or using prohibited gear will require proof of whether the alleged offence occurred above or below the relevant seaward limit. That proof may require expert testimony as to grid references, location of white posts, or the state of bridges at the relevant time.

The Inland Fisheries (Seaward Limits) Order 2004 imposes no direct duties and confers no direct rights. All duties and rights arise from the Inland Fisheries Act 1995, which incorporates the seaward limits by reference. However, the Order creates a de facto duty on any person who fishes in a listed watercourse to ascertain their location relative to the seaward limit. That duty is not stated in the Order but flows from the Act’s requirement that a person must not fish in inland waters without a licence or in a manner contrary to the Act. A person unaware of the boundary can still be liable. The corresponding right is the right to fish in those waters beyond the seaward limit without an inland fisheries licence, subject to meeting the requirements of the applicable coastal fisheries legislation. For the State, the Order delineates the extent of its regulatory power under the Inland Fisheries Act 1995. The Crown’s right to enforce inland fisheries laws extends only to waters within the defined seaward limits. Beyond those limits, enforcement falls to other agencies. This division also affects the rights of licensed inland fishers: they cannot claim any exclusive right to fish in waters beyond the seaward limits simply because they hold an inland licence. Conversely, a person holding only a coastal licence must not fish within the inland waters defined by the Order. The Order also indirectly affects the right to use certain fishing gear. For example, if a particular method (such as using a net or a set line) is prohibited inland but permitted in tidal waters, the boundary is the legal line between legality and illegality. Commercial fishers who operate near river mouths must be especially careful: the same reach of water can shift jurisdiction depending on tides or seasonal changes, but the Order fixes a static line. The Order does not create any property right in the watercourse itself. It does not grant access to land, or authorise fishing from private property. Those rights are governed by other laws. The Order also does not affect any native title rights or interests, though those could intersect with the fishery regulation. The only right the Order arguably creates is the right of a person to rely on the definitions in Schedule 1 for legal certainty. If a person can demonstrate that they were fishing at a location that the Order defines as inland waters, they are presumptively subject to the Act; within tidal waters they presumptively are not. That certainty is valuable but not absolute, as the state may still argue that the physical feature used as a reference point has changed since the Order was made.

The Inland Fisheries (Seaward Limits) Order 2004 itself contains no penalty provisions. It is a definitional instrument only. Penalties for fishing in inland waters without a licence, or for breaching inland fisheries rules, are found in the Inland Fisheries Act 1995. That Act creates offences such as fishing in inland waters without a licence (s 14), using prohibited gear, exceeding bag limits, or possessing illegal species. Penalties for those offences can include fines, forfeiture of equipment, and in some cases imprisonment, though the Order does not list them. Enforcement is carried out by the Inland Fisheries Service, which employs fisheries officers with powers of entry, inspection, search, seizure, and arrest under the Act. Police also have enforcement powers. In any prosecution, the location of the alleged offence relative to the seaward limit will be an element that the prosecution must prove beyond reasonable doubt. The prosecution will need to adduce evidence that the person was fishing at a point upstream of the defined limit for the relevant watercourse. That evidence may include GPS coordinates, photographs, testimony from officers who observed the person, and expert evidence interpreting the Schedule 1 definition. If the definition uses a white post, the prosecution must prove that the post existed at the time and was located at the correct place. If the definition uses the downstream side of a bridge, the prosecution may need to demonstrate where the downstream side was at the time, which may be affected by bridge replacements or modifications. The defence may challenge the evidence if the reference point has moved or is ambiguous. The revocation of the 1996 Order does not affect liability for offences committed before the 2004 Order came into effect. The 2004 Order took effect on the day it was notified in the Gazette, which was 10 March 2004. Any offence before that date would be prosecuted using the 1996 boundaries. There is no penalty for failing to know the boundary, but ignorance of the boundary is no defence to a charge of fishing without a licence or using prohibited gear in inland waters. Given the complexity of some definitions, this places a high practical burden on fishers, particularly those who fish near tidal limits. The enforcement risk is concentrated on those who fish in estuaries and lower reaches of the 75 listed rivers, especially where the boundary is not marked by any physical signpost. White posts are only present for a few rivers; for most there is no visible marker. The enforcement agency bears the cost of proving the location, but the fisher bears the risk of prosecution if mistaken.

The Inland Fisheries (Seaward Limits) Order 2004 operates as a delegation from the Inland Fisheries Act 1995. Section references within the Order itself are minimal, but the relationship is structural: the Act defines the Commissioner of Inland Fisheries’ jurisdiction by reference to “inland waters”, and the Order specifies the outer limit of those waters for the listed rivers. Beyond those limits, the Living Marine Resources Management Act 1995 and its subordinate instruments, such as the Fisheries (Scalefish) Rules, the Fisheries (Abalone) Rules, and the Fisheries (Rock Lobster) Rules, generally apply. The boundary also matters for the Water Management Act 1999, which defines “watercourse” and may use the same seaward limits for its own purposes, though not necessarily. The Land Use Planning and Approvals Act 1993 may trigger different assessment pathways for developments within or near inland waters versus coastal waters. The Marine Farming Planning Act 1995 applies to marine farming in coastal waters, and its area of operation begins where the Inland Fisheries Act ends: that is, at the seaward limit defined by this Order. The revocation of the 1996 Order raises transitional interaction issues. Any licence, lease, permit, or approval that referenced the 1996 boundaries is now governed by the 2004 boundaries. A person who holds a licence to fish in inland waters that specifically names a river might find that the area they can lawfully fish has changed if the 2004 definition places the seaward limit further upstream or downstream than the 1996 definition did. The Order does not contain a savings provision, but the primary Act may have transitional provisions. The Order also interacts with Commonwealth law, particularly the Fisheries Management Act 1991 (Cth), which applies to offshore fisheries beyond three nautical miles. The seaward limits of Tasmanian rivers are a state matter, but if a river mouth is also a boundary of a Commonwealth fishery, the definitions could create jurisdictional gaps or overlaps. The Order does not address these interactions, so they must be resolved by reference to the Australian Coastal Waters (State Powers) Act 1980 (Cth) and the Offshore Constitutional Settlement. The reference in the Order to the “classification of roads used in Tasmania” also means its interpretation depends on the state’s road naming authority. If a road is reclassified or renamed, the bridge reference in the Order continues to refer to the road as classified when the Order was made, unless the Order is amended. This is a potential source of confusion. Finally, the Order interacts with the Rules Publication Act 1953, which governs the notification and publication of subordinate legislation; the Order notes it is displayed and numbered in accordance with that Act.

The Inland Fisheries (Seaward Limits) Order 2004 was notified in the Gazette on 10 March 2004 and took effect that day, as provided by clause 2. It revoked the Inland Fisheries (Seaward Limits) Order 1996 (SR 1996, No. 75). The only subsequent amendment to the 2004 Order is recorded in the source text: Schedule 1 was amended by S.R. 2010, No. 82, applied on 18 August 2010. The source text notes this amendment with the annotation “[Schedule 1 Amended by S.R. 2010, No. 82, Applied:18 Aug 2010]”. The content of the amendment is not specified in the source, but it may have added, deleted, or altered entries in the Schedule. The numbering of the entries in the current text is sequential from 1 to 75 except that there is no entry 54. Entry 54 appears to be missing, possibly because a river was removed in the 2010 amendment or because of a numbering error. The presence of a gap at number 54 suggests that the 2010 amendment may have deleted an entry. The Order itself is administered by the Department of Primary Industries, Water and Environment, as stated at the end of the source. The amendment history shows that the Order is not immutable; it can be amended by subsequent subordinate legislation. Users of the Order must check whether further amendments have been made since 2010. The current version as displayed in the source is dated 12 April 2026, indicated by the URL snippets /view/html/inforce/2026-04-12/. This suggests that the Tasmanian legislation website has compiled an authorised version as at that date, but the user should confirm whether any later amendments exist. The 1996 Order is now revoked and has no legal effect. The 2004 Order replaces it entirely. The 2010 amendment is the only one recorded in the source, but there may be others not captured in the text provided. The static nature of the Order since 2010 may indicate that the boundaries have been accepted by stakeholders, or it may indicate that the government has not prioritised updating the definitions as physical features change.

The Inland Fisheries (Seaward Limits) Order 2004 is a definitional instrument and is not the direct subject of reported litigation in the source text. The source does not name any cases. However, it is likely that the Order has been considered in prosecutions under the Inland Fisheries Act 1995 where the location of the alleged offence relative to a seaward limit was in dispute. In such cases, the court would need to interpret the Order’s definitions. For example, a court may have considered the meaning of “the downstream side of a bridge” when the bridge has been replaced, or the meaning of “an imaginary straight line” when the endpoints are no longer visible. It may also have considered whether the grid reference system used is the one current at the time of the Order or at the time of the alleged offence. No such cases are identified in the source. The absence of noted litigation does not mean none exists; it only means the source does not refer to any. A practitioner would need to search databases such as AustLII for Tasmanian cases citing the Order or the 1996 predecessor. The revocation of the 1996 Order might have generated litigation if someone was prosecuted for an offence that straddled the date of revocation, but again the source does not reveal this. The Order’s reliance on physical infrastructure (bridges, white posts, wharfs) creates potential for disputes when those features are altered or destroyed. The 2010 amendment may have been prompted by such a dispute or by routine review. Future litigation is possible if a road is reclassified or a bridge replaced, leading to disagreement over where the downstream side now falls. The lack of a definition for “white post” or “ballast wharf” in the Order’s interpretation clause is a litigation risk: a court would need to determine the intended meaning, potentially using extrinsic materials such as the explanatory memorandum (if any exists) or the 1996 Order. The grid references are unlikely to be challenged on their own unless they are demonstrably wrong under the Universal Grid Reference System as applied in Tasmania at the time of the Order. Overall, the Order is a low-litigation instrument because its terms are relatively clear and its effect is primarily administrative, but it can become a central issue in any individual fishing prosecution.

Several features of the Inland Fisheries (Seaward Limits) Order 2004 are likely to catch out practitioners and fishers alike. First, the Schedule contains a gap at number 54; there is entry 53 (Pipers River) followed by entry 55 (Prosser River). There is no entry 54. This is either a deletion by the 2010 amendment or a drafting anomaly. A person looking for a river that might have been number 54 must search elsewhere; that river may now be omitted from the Order altogether, meaning its seaward limit is not defined by this instrument and the default definition of inland waters in the Inland Fisheries Act 1995 applies. That default definition may be ambiguous. Second, many definitions rely on grid references, but the Order does not specify which edition of the Universal Grid Reference System is to be used, nor does it provide any datum information. Grid references can shift between map datums (e.g., AGD66 vs. GDA94), potentially moving the boundary by hundreds of metres. The prudent user must check the datum that was current in Tasmania when the Order was made in 2004. Third, the “downstream side” of a bridge is a phrase that sounds obvious but becomes ambiguous when a bridge is not perpendicular to the flow, when the bridge has been widened or replaced, or when the river has changed its course. The Order does not specify whether “downstream side” is determined by the actual direction of flow at the time of the Order or by the hydraulic design of the bridge. Fourth, the reliance on white posts (e.g., Apsley River, Huon River, Muddy Creek) assumes the posts remain in place and are recognisable. There is no requirement in the Order for the posts to be maintained or replaced. If a post is removed by a storm, vandalism, or landowner action, the boundary becomes uncertain. The court would then need to reconstruct the intended line from extrinsic evidence. Fifth, the reference to roads by capital letter and numeral (e.g., A2, B84) ties the definition to the road classification system used in Tasmania at the time of the Order. Roads can be reclassified (A2 becomes a B road, or the road is bypassed by a new highway). The bridge reference then points to the wrong road classification. A person trying to locate the bridge today may find that the road no longer exists or has a different number. Sixth, some definitions refer to bridges carrying a “railway” (e.g., Camp Creek, Don River, Sulphur Creek). Railway lines can be removed or reconfigured; the bridge may still be there, but the railway crossing the bridge may not exist. The definition still refers to the bridge by its railway connection, which may confuse those looking for a railway bridge that no longer carries trains. Seventh, the words “imaginary straight line” are used repeatedly, but the endpoints of those lines are sometimes described in ways that assume geographic knowledge that may not be obvious to a modern GPS user. For example, the Derwent River’s limit is “the parallel of latitude of the eastern extremity of Dogshear Point”. This requires the user to locate Dogshear Point and then draw a line due east-west. No grid reference is given for Dogshear Point. Eighth, the Order does not define “mouth” for the rivers where that term is used. The hydrological mouth of a river may differ from the legal mouth as defined by a grid reference; the Order’s grid reference is conclusive, but if the grid reference is incorrectly located, the legal mouth may not be the actual mouth. Ninth, the Order’s commencement provision (clause 2) says it takes effect on the day its making is notified in the Gazette. That means it could have taken effect before most people had a copy of the Order. Finally, the revocation of the 1996 Order means any licence, lease, or approval that referred to the 1996 boundaries is no longer effective for defining the seaward limits. Practitioners must ensure they are using the 2004 boundaries for any fact situation after 10 March 2004.

Compliance with the Inland Fisheries (Seaward Limits) Order 2004 is not a matter of filing forms or paying fees. It is about correctly determining one’s location relative to the defined seaward limits before engaging in any activity regulated by the Inland Fisheries Act 1995. For a recreational fisher, the first step is to confirm whether the watercourse they intend to fish in is listed in Schedule 1. If it is not listed, the seaward limit is determined by the default definition in the Inland Fisheries Act 1995, which is likely the tidal limit or the mouth of the river as defined by the common law. If it is listed, the fisher must find the specific limit definition for that river. For definitions using a grid reference, the fisher should acquire a GPS device or smartphone with GPS capability and ensure it is set to the correct datum (WGS84 is standard for most consumer GPS devices, but the Order’s grid references may have been drawn from AGD66 or GDA94). They should then navigate to the exact coordinate and check whether they are upstream or downstream of that point. For definitions using a bridge, the fisher must identify the specific bridge using the road classification given. They should then stand on or near the bridge and determine which side of the bridge, in the direction of flow, is covered by the Inland Fisheries Act. They should fish only upstream of that side. For definitions using an imaginary straight line between two points, the fisher should find both endpoints on a map or GPS and stay well upstream of the line connecting them. For definitions using white posts, the fisher should locate the posts if they are still present, or rely on a map that shows their approximate location. Because the posts may be missing, the safest approach is to treat the whole estuary zone as inland waters unless one can be certain of being downstream of the historic post locations. For commercial fishers and charter operators, a higher standard of care applies. They should maintain maps or GPS waypoints marking each seaward limit they operate near. They should also keep a record of any changes to infrastructure, such as bridge replacements or road reclassifications, and adjust their waypoints accordingly. Operators who use nets or fixed gear should ensure that the gear is not set in a location that straddles the boundary. For developers and landholders near listed watercourses, the seaward limit affects approval pathways. They should obtain a survey of the boundary relative to their property, especially if the definition uses an imaginary line or grid reference. They should also check whether the 2010 amendment changed the boundary from the 1996 version. The Inland Fisheries Service may be able to provide guidance or maps, but the ultimate responsibility rests on the person conducting the activity. Keeping a copy of the current authorised version of the Order (as at the relevant date) is essential. For anyone facing a potential prosecution, compliance is about having credible evidence of the location. This could include a GPS track log, contemporaneous photographs, or a witness who can confirm the position relative to the defined limit. Ignorance of the boundary is not a defence, so proactive mapping and education are the only practical compliance strategies.
