Defence (Remote ILS/TACAN Site Beermullah Defence Aviation Area) Declaration 2018

The instrument operates through a small set of legal mechanics: declaration, mapping, legend-based specification, and incorporation by statutory reference. Each concept is stated in the instrument and tied to the Defence Act.

• Declaration: The Minister exercises the power in subsection 117AC(1) of the Act to declare an area to be a defence aviation area. The declaration language is procedural: “For the purposes of subsection 117AC(1) of the Act, the Remote ILS/TACAN Site Beermullah Defence Aviation Area is declared to be a defence aviation area” (s 5(1)). The instrument therefore adopts the statutory mechanism rather than creating an independent regulatory regime.

• Map-defined area: The area’s boundaries are determined by a map in Schedule 1. The instrument repeatedly anchors geographic scope to the map: the area is “the areas of land ... depicted on the map set out in Schedule 1” (s 5(2)). The instrument explicitly carves out white space on the map as excluded: “areas depicted by white space on the map set out in Schedule 1 are not included” (s 5(3)). The map is the operative spatial definition.

• Height restrictions: The instrument invokes subsection 117AC(3) by specifying that height restrictions apply to buildings, structures and objects, expressly including trees and other natural obstacles (s 6(1)). The detailed numeric or categorical limits are not reproduced in the instrument body; instead they are set out in the map legend in Schedule 1 and apply to the corresponding mapped areas (s 6(2)).

• Reference to the Defence Act: The instrument defines “Act means the Defence Act 1903” (s 4) and notes that a number of expressions are defined in s 4 of the Act, including “defence aviation area”. The instrument thus depends on the Act for definitions, context and legal grounding.

• Commencement linkage: The instrument comes into force at the same time as a provision of another statute, the Defence Legislation Amendment (Instrument Making) Act 2017, Schedule 1, Part 2 (s 2). The commencement of this instrument therefore depends on a separate statutory timeline.

Mechanically, therefore, the instrument imposes regulatory constraints on the physical height of built and natural features within specified mapped zones, and does so by tying the restrictions to a map legend. The instrument does not itself enumerate penalties, procedures for approvals, notices, exemptions, compensation mechanisms, or enforcement processes; those matters, to the extent relevant, will derive from the Act to which the instrument is subordinate and which supplies the definitions referenced.

The instrument’s immediate legal effect is spatial and feature-based. Those directly affected are persons who own or control land, buildings, structures, objects or vegetation located inside the mapped area in Schedule 1. Section 6(1) expressly applies the height restrictions to “buildings, structures and objects (including trees and other natural obstacles)” within the Remote ILS/TACAN Site Beermullah Defence Aviation Area. Therefore private landowners, occupiers, developers, builders, forestry managers and land managers with assets in the depicted area will be the principal parties who must take action to comply with the height limitations.

Because the declared area is defined by a map rather than by textual coordinates, any party with property that lies near the map boundary must consult the Schedule 1 map to determine inclusion or exclusion. The instrument also expressly excludes “areas depicted by white space” on the map from the declared area (s 5(3)), so the map’s graphic presentation can determine whether individual parcels are affected.

The Minister for Defence Personnel is the decision-maker who made the declaration under statutory power (front page and s 3). The Act provides the statutory legal authority for the instrument, and the instrument depends on the Act’s definitions and the referenced subsections (s 4). The instrument does not itself identify a local authority or administrative office to give approvals or vary restrictions. It therefore places initial legal responsibility on landowners and on Defence (as the issuer) to interpret and implement the map-based restrictions, but it does not specify the administrative pathway for enquiries, approvals, or notifications.

Indirectly affected stakeholders include adjoining landowners and infrastructure operators whose planning envelopes, construction phasing or vegetation management may be constrained by the new map-based limits. The instrument does not address compensation, acquisition, easements or notices to landowners; the absence of those provisions means that landowners must look to the Act or other administrative practice for procedural protections or remedies. Finally, contractors, surveyors, planners and environmental managers working on property within or adjacent to the map will face additional due-diligence obligations to check the Schedule 1 map and legend.

The instrument’s express legal content creates a modest set of duties and situational rights by reference rather than by full articulation.

Express duties established by the instrument

• Compliance with height restrictions: The instrument specifies that height restrictions apply to buildings, structures and objects, including trees and natural obstacles, within the declared area (s 6(1)). The practical duty is to ensure that those items do not contravene the applicable heights set out in the legend to the map (s 6(2)). The instrument does not itself articulate how compliance is to be demonstrated or enforced.

• Geographic determinism: A duty to consult the Schedule 1 map arises in practice. The instrument makes the map the binding determinant of whether land is inside the declared area (s 5(2)), and expressly excludes white-space areas (s 5(3)). Parties who want to know their obligations therefore must use the Schedule 1 map as the legal reference.

Matters declared but not specified in the instrument

• The instrument points to subsection 117AC(3) of the Act by saying the height restrictions apply “for the purposes of subsection 117AC(3)” (s 6(1)). Because the instrument does not reproduce subsection 117AC(3), the full scope of statutory duties, powers to approve or exempt, or any enforcement powers or processes that flow from that subsection are not set out in the instrument. Those procedural or remedial elements must be located in the Act itself.

Rights and omissions

• The instrument does not articulate rights to compensation, procedural notice, administrative review, or appeal. It also does not grant explicit rights to continue existing uses or structures (no “grandfathering” clause is present in the instrument text). The absence of those clauses is legally significant: affected persons must look to the Defence Act or other laws for any express statutory protections, or to administrative practice.

• The instrument does not set out a mechanism for seeking variations, deferrals or permits within the declared area. The only rights that can be identified within the instrument itself are those implicit in having to consult the map and conform to the height legend; the instrument does not create or disclaim any other statutory rights.

In short, the instrument places a rule-like constraint (map-based height limits) on the use and management of land and objects within the mapped area (s 6(1)-(2)), but it delegates substantive detail about administration, remedies and exceptions to the underlying Defence Act and to the map legend in Schedule 1. Parties should therefore treat the instrument as creating the substantive restriction while relying on the Act for procedural and remedial detail.

The instrument does not itself specify penalties, enforcement powers or administrative processes. It is an enabling declaration that relies on subsection 117AC of the Defence Act 1903 as its statutory authority (s 3). Because the instrument limits itself to declaring the area and specifying that height restrictions apply under s 117AC(3) (s 6(1)), any enforcement powers, sanctions, notice requirements, or contravention consequences must be found in the Act or in other instruments made under the Act. The instrument does not reproduce those provisions.

Practical implications of the instrument’s silence

• Enforcement locus is external: Enforcement, if any, must be exercised under the Act. The instrument’s silence as to who enforces, how investigations are initiated, what process is required before action, and what penalties are available means that the legal consequences of non-compliance cannot be identified from the instrument alone. Affected persons must therefore consult the Defence Act for the operational enforcement regime.

• Uncertainty for compliance planning: Because the instrument does not state the consequences of non-compliance or the remedial paths Defence may adopt, landowners and developers face legal uncertainty when estimating enforcement risk and potential liabilities. That uncertainty is material for project planning and budgeting.

• No administrative contact, no permit pathway in text: The instrument does not provide an administrative contact, directions about notices, or a permit/authorisation pathway that would govern variances. From the instrument alone, there is no express mechanism for seeking exemptions or approvals.

Where this leaves stakeholders

• To identify enforcement risk quantitatively and procedurally, affected parties must read s 117AC and related provisions of the Defence Act. The instrument anchors regulation at the level of land-use and height but delegates enforcement mechanisms to the broader statutory framework. The instrument’s legal weight derives from the Act under which it is made (s 3), yet the instrument itself is silent on enforcement and penalties.

The instrument is explicitly subordinate to and dependent on the Defence Act 1903, and it links its commencement to another amending statute. The instrument defines “Act” to mean the Defence Act 1903 (s 4) and repeatedly cites specific subsections of the Act as the source of power (s 3 refers to subsection 117AC(1); s 6 refers to subsection 117AC(3)). This establishes a layered relationship: the instrument operates as an instrument under the Act rather than as an autonomous piece of law.

Commencement dependency

• The instrument commences at the same time as the Defence Legislation Amendment (Instrument Making) Act 2017, Schedule 1, Part 2 (s 2). Practitioners and affected parties therefore must consider the commencement timeline of that amending statute when establishing when the declaration became operative. The instrument’s effect is therefore temporally linked to the legislative timetable of the 2017 amending Act.

Definitions and other statutory cross-references

• The instrument expressly incorporates the Act’s definitions by reference (s 4), noting that expressions such as “defence aviation area” are defined in section 4 of the Act. Consequently, the legal meaning and consequences of terms used in the instrument depend upon their statutory definitions in the Defence Act.

Spatial law interactions

• The instrument defines the affected area by a map in Schedule 1 rather than by coordinates or cadastral references (s 5(2)). That mapping approach means that cadastral law, local planning law and land title registers will need to be consulted to determine, for any particular parcel, whether it is captured by the declaration. The instrument does not override land title; it imposes a regulatory overlay that may affect permitted uses, approvals and development rights that are otherwise governed by local planning instruments and property law. The instrument does not mention interactions with state planning law, local government approval processes, or native title, and it does not state whether it is intended to displace or co-exist with those regimes.

Absence of cross-references to compensation, acquisition or easements

• The instrument does not address compensation, acquisition, easements, or notice regimes that might be found in land or administrative law. If the height restrictions constrain existing lawful uses or create operational burdens for landholders, remedies or compensation, if any, would need to be sought under the Defence Act or under separate laws; they are not created or disclaimed in the instrument.

In sum, the instrument is an Act-based regulatory overlay that files into the Defence Act’s architecture, commences with the 2017 instrument-making amendment, uses a map to set spatial boundaries and imports Definitions from the Act. It does not itself set out cross-system procedural interactions, leaving those matters to the Act and to other statutory or administrative frameworks.

The instrument carries its own single-date signature and a linked commencement statement, and it records no subsequent amendments within the text provided.

• Date and authorising instrument: The declaration bears the signature and date of the Minister for Defence Personnel, Darren Chester, dated 16 March 2018 (front page). Section 3 records that the instrument is made under subsection 117AC(1) of the Defence Act 1903.

• Commencement linkage to prior amending Act: The instrument commences “at the same time as the Defence Legislation Amendment (Instrument Making) Act 2017, Schedule 1, Part 2” (s 2). That establishes the instrument’s operative date as contingent on the commencement of that amendment provision rather than on the instrument’s own date of signature alone. The instrument does not state a separate commencement date (for example, “on gazettal”) and therefore practitioners must check the commencement date of the 2017 amending Act to know when the declaration became effective.

• No internal amendment clauses: The instrument contains no clauses amending prior instruments or schedules, nor does it contain transitional provisions, sunset clauses, review dates, or express powers to vary the map or legend. Any variation to the declared area or the legend-based height restrictions would therefore require a further instrument made under the Act, or amendment to this instrument, dated and published in accordance with the Act’s instrument-making requirements.

• No recorded subsequent amendments in the text provided: The instrument as provided contains no record of later amendment or revocation. The Schedule 1 map is an integral part of the declaration; any change to the geographic footprint or legend would require formal amendment to Schedule 1.

Practitioners tracking the legal status of this declaration should therefore check legislative and instrument registers for any later instruments amending or revoking this 2018 declaration, and should also verify the practical commencement date by reference to the Defence Legislation Amendment (Instrument Making) Act 2017, Schedule 1, Part 2.

The instrument itself contains no litigation history and does not record any judicial or administrative decisions about its validity, scope, or application. The text provided does not cite cases, disputes, appeals or determinations. It therefore carries no internal account of challenges or rulings.

Consequences of that absence

• There are no precedents, judicial interpretations, or published disputes within this instrument to clarify ambiguous points such as the map-reading rules, the operation of the legend, the interaction with private rights, or the interpretation of “in the vicinity of” as used in the geographic description (s 5(2)). Any clarifying judicial or administrative guidance would need to be sought from subsequent case law or tribunal decisions, none of which are referenced here.

• For risk assessment, affected parties must assume that litigation history, if any, must be discovered through external research in court records, tribunal decisions, or administrative reviews. The instrument does not guide readers to that material.

• The instrument’s silence does not imply that the declaration has not been litigated; it simply contains no record of litigation. Practitioners should therefore perform a jurisdictional search for cases involving subsection 117AC of the Defence Act or disputes about defence aviation areas generally, to see if there is relevant authority interpreting map-based declarations, height-restriction legends, or procedural protections under the Act. That research is outside the instrument’s text and must be done in external databases.

In sum, there is no litigation history contained in the instrument. Any judicial or administrative clarifications about its meaning, scope or enforcement must be sourced outside the instrument.

The instrument’s brevity and map-based approach produce several practical and legal pitfalls that practitioners and affected parties should note.

1. Operational reliance on a map that is part of the instrument

• The declaration’s geographic scope is map-defined (s 5(2)). The instrument excludes areas shown as white space (s 5(3)). If the Schedule 1 map is not reproduced in a usable, georeferenced form alongside cadastral boundaries, determining whether a given parcel is included may require interpretation or surveying. The instrument does not supply coordinates or textual parcel descriptions.

2. Height restrictions only in the map legend

• The instrument does not state numerical height limits in the main text; instead it defers to the map legend in Schedule 1 (s 6(2)). If the legend is ambiguous, lacks units, or is not reproduced at the scale needed for precise measurement, parties cannot deduce the applicable limits from the instrument alone. The map legend therefore becomes legally material but potentially technically difficult to apply without additional geospatial data.

3. Inclusion of trees and natural obstacles

• Section 6(1) explicitly includes trees and “other natural obstacles” within the scope of restricted items. This language can capture vegetation management obligations and suggests that landowners with native trees or regrowth on their land could be required to manage natural features to comply. The instrument does not set out whether pruning or removal permissions, environmental approvals, or offsets are required or how those intersect with other laws.

4. No procedural or remedial detail

• The instrument does not set out a permit process, notice requirements, exemption mechanisms, or compensation rules. Parties cannot infer from the instrument whether an existing non-conforming structure is exempt, whether there is a transitional compliance period, or what remedies are available if Defence requires a change. The instrument’s reference to subsection 117AC(3) (s 6(1)) suggests those matters may be addressed in the Act, but they are not in the instrument itself.

5. Commencement dependency may create timing traps

• Because the instrument commences simultaneously with a provision of an amending Act (s 2), parties cannot automatically rely on the instrument’s signature date (16 March 2018) as the operational start date. Projects in progress around that time need to check the commencement date of the 2017 amending Act to determine whether the declaration affected planning decisions or approvals.

6. Potential overlap with other regulatory regimes

• The instrument does not address how its restrictions interact with state or local planning decisions, native vegetation laws, or infrastructure approvals. An affected landowner may face overlapping obligations but no coordinating mechanism is described in the instrument.

7. Administrative uncertainty about points of contact

• The instrument does not identify an administrative office, advice line, or application process for queries, height approvals or mapping clarifications. Practitioners will need to approach Defence or consult the Defence Act and government instrument registers to identify the correct administrative channel.

8. No statement on rights to compensation, acquisition or continued use

• The instrument does not create or displace rights to compensation or acquisition, nor does it provide for continuity of pre-existing uses. If the restrictions materially impair existing uses, the instrument does not itself explain the landowner’s recourse.

Each of these items follows from the instrument’s text: it is short, map-dependent, and silent on administration, remediation and cross-framework interactions. The practical cost and legal uncertainty created by those silences are therefore the principal “gotchas” to account for when advising clients or planning on parcels near the mapped area.

The instrument itself sets out a tight compliance pathway: identify whether land or objects fall within the map in Schedule 1, then ensure that buildings, structures and objects (including trees and other natural obstacles) conform with the map legend’s height restrictions. The following steps translate the instrument’s text into a pragmatic checklist.

1. Determine whether the land or asset is within the declared area

• Obtain a copy of Schedule 1 as it appears in the instrument, in a sufficiently detailed and georeferenced form to be overlayed on cadastral title maps. The instrument’s operative boundary language is map-dependent (s 5(2)), and white-space exclusion is explicit (s 5(3)). If the Schedule 1 map is not sufficiently precise, commission a survey or a GIS overlay to confirm whether a parcel or asset is within the declared area.

2. Read and apply the legend in Schedule 1

• The instrument specifies that height restrictions are those “described in the legend to the map set out in Schedule 1” and that they apply in the corresponding depicted areas (s 6(2)). For each sub-area on the Schedule 1 map, record the applicable height limit from the legend. Verify units and measurement baselines used in the legend if they are not explicit.

3. Audit existing buildings, structures, objects and vegetation

• Section 6(1) explicitly includes trees and natural obstacles. Conduct an inventory of all buildings, structures, tall equipment, masts, antennas, and vegetation within the mapped footprint. Measure current heights against the map-legend limits and identify any non-conforming items.

4. Determine remedial action and timeline

• For non-conforming items, prepare a compliance plan setting out whether to modify, remove or otherwise manage the item to meet the legend’s limits. The instrument does not specify transition periods or exemptions, therefore account for the possibility that remedial action may need to occur promptly once the declaration is operative.

5. Consult the Defence Act for procedural, enforcement and remedial detail

• The instrument is made under subsection 117AC(1) and refers to subsection 117AC(3) (s 3 and s 6(1)). To understand whether applications for exemption, procedural notice requirements, or enforcement penalties exist, consult those parts of the Defence Act. Do not assume that the instrument itself provides a permit route or sets enforcement standards.

6. Check commencement timing

• The instrument commences with the Defence Legislation Amendment (Instrument Making) Act 2017, Schedule 1, Part 2 (s 2). Confirm the commencement date of that amending Act to know when the obligations began to apply. Where projects straddle the commencement date, review existing approvals and consult legal counsel on any transitional exposure.

7. Engage early with Defence

• Although the instrument does not provide an administrative contact, the declaration is a Defence instrument. For practical compliance and to reduce enforcement risk, contact the relevant Defence administrative office for guidance, clarification of the legend, and any established application or notification process. Request written confirmation of any agreed timelines or exemptions.

8. Integrate into planning and forestry practices

• For developers and land managers, incorporate the declared area’s limits into planning approvals, building permits and vegetation management plans. Ensure consultants, surveyors and contractors are aware of the map-based constraints and check requirements before commencing work.

9. Document compliance and decisions

• Keep records of map consultations, measurements, correspondence with Defence, remediation plans, and any approvals or informal acknowledgements. The instrument itself provides limited procedural detail; contemporaneous documentation will assist if enforcement or dispute arises.

10. Consider legal advice where rights or costs are materially affected

• If the height restrictions materially impair the economic use of land, or if the map’s boundaries are contested, seek legal advice. Because the instrument does not address compensation, acquisition or dispute resolution, counsel can assist with framing any administrative review, seeking declaratory advice from Defence, or exploring statutory remedies under the Defence Act.

These steps are directly derived from the instrument’s operative clauses: the map in Schedule 1 determines inclusion (s 5(2)), white space is excluded (s 5(3)), and height restrictions for buildings, structures and natural obstacles are set by the legend (s 6(1)-(2)). The instrument’s silence on procedural pathways necessitates proactive engagement with Defence and careful documentary practice.
