Radiocommunications (Spectrum Re-allocation—3.6 GHz Band for Perth) Declaration 2018

The instrument uses a small set of legal concepts; each carries operative consequences only through the Act that the instrument invokes. The main concepts and their legal mechanics in this instrument are:

• Spectrum re-allocation subject to Part 3.6 of the Radiocommunications Act 1992 (s 5(1)). The instrument does not reproduce Part 3.6; it places the frequencies and geographic area within Part 3.6’s processes. The operative mechanism named is issuance of spectrum licences under Subdivision B of Division 1 of Part 3.2 (s 5(1)(a) and cross-reference to s 153L of the Act).

• Spectrum band as a closed interval (s 4(2)). The instrument states that a reference to a part of the spectrum includes all frequencies greater than the lower frequency, up to and including the higher frequency. Applied to s 5(1), that makes the band 3575 MHz to 3700 MHz inclusive of 3700 MHz and exclusive of frequencies at or below 3575 MHz.

• Re-allocation period and re-allocation deadline (s 5(2)). The instrument fixes two temporal concepts. The re-allocation period is a 5-year interval that begins at the start of the 21st day after commencement. The re-allocation deadline is the end of the day before the first anniversary of that start. These temporal definitions will interact with the Act’s procedural deadlines and power to require reconfiguration or to award licences (the instrument itself does not state those procedural consequences; they rest with Part 3.6 of the Act).

• Named area defined by HCIS identifiers (s 5(3)). The instrument defines the geographic area using the Hierarchical Cell Identification Scheme (HCIS) as used in the Australian Spectrum Map Grid 2012. The table lists dozens of HCIS identifiers (BV1E through BV5J6, including intermediate and multi-part identifiers), and the instrument contains notes pointing consumers toward ACMA’s ASMG and conversion tools on the ACMA website (s 5(3) notes).

• Authority by statutory provision (cl 3). The instrument explicitly states it is made under subsection 153B(1) of the Radiocommunications Act 1992 (cl 3). The choice of that enabling subsection places the instrument within the Act’s delegation architecture and ties its validity and operation to the Act’s terms and procedures.

• Referential incorporation of Act definitions (s 4 note). The instrument relies on defined terms in the Act, rather than redefining them. The instrument’s operative effect is therefore mediated by the Act’s interpretation and enforcement provisions.

Those core concepts are the only substantive legal levers in the instrument. The instrument does not create licence classes, pricing rules, auction terms, displacement arrangements, or transitional relief; it activates the Act’s re-allocation machinery in respect of the specified band and HCIS-defined area and fixes the timing for the re-allocation period and deadline.

The instrument directly and indirectly affects three categories of actors by its terms:

• ACMA and its administrative processes. The instrument is made under s 153B(1) of the Act (cl 3) and specifies that re-allocation will proceed by issuing spectrum licences under Subdivision B Division 1 Part 3.2 (s 5(1)(a)). That allocative action is within the ACMA’s functions under the Act (the instrument does not set licence rules but activates ACMA’s licensing function in that band and area). Therefore ACMA is the decision-making authority that will administer the consequences flowing from this declaration.

• Parties with an interest in spectrum licences for 3575-3700 MHz in the Perth HCIS area. The instrument makes that band and area subject to re-allocation and specifically ties the process to the spectrum-licence mechanism in the Act (s 5(1)). Entities that currently hold spectrum licences, apparatus licences, or other radiocommunications authorisations that rely on that specific frequency range and fall within the listed HCIS areas are potentially affected by re-allocation procedures under Part 3.6. The instrument itself does not enumerate incumbents, compensation, or transitional arrangements; those matters are to be addressed under the Act’s Part 3.6 and associated provisions.

• Prospective licence applicants, bidders and commercial users. Because the instrument contemplates issuance of spectrum licences (s 5(1)(a)), commercial firms seeking rights to use 3575-3700 MHz in the named HCIS areas will be affected in that the re-allocation creates an opportunity to obtain licences through the Part 3.6 process. The timing formula (s 5(2)) gives prospective applicants a calendared window for the re-allocation period and a deadline relevant to the Act’s processes.

Collateral affected parties include equipment vendors, network operators and service providers who design or operate equipment within the 3575-3700 MHz band in the named HCIS areas. The instrument does not list transitional obligations or technical parameters; however, making the band subject to re-allocation creates a possibility of changed licensing outcomes, which may require reconfiguration or re-provisioning of services , such consequences will be realised through Part 3.6 procedures and ACMA decisions, not by the declaration text itself.

Finally, geographic stakeholders , local governments, infrastructure providers and landlords in Perth , are indirectly affected because the geographic extent of the declaration is defined by specific HCIS identifiers (s 5(3)). The instrument makes the precise mapping mechanism central: the HCIS as used in the Australian Spectrum Map Grid 2012 and ACMA’s published spatial datasets (s 4(1) and s 5(3) notes). Those datasets are operative for identifying whether a particular site or operation lies within the named area.

The instrument itself imposes no express new criminal penalties, licence conditions, monetary fees or affirmative duties. Instead it confers legal effects by triggering existing statutory procedures in the Radiocommunications Act 1992. The key duties and rights to note, as derived from the instrument’s text, are:

• Right of ACMA to issue spectrum licences in the named band and area (s 5(1)(a)). The instrument specifies that re-allocation will occur by issuing spectrum licences under Subdivision B Division 1 Part 3.2 of the Act. The right to issue licences, and whatever conditions, processes and remedies the Act supplies for that issuance, rest with ACMA as provided by the Act. The instrument does not itself set licence conditions.

• Temporal rights and processes tied to the re-allocation period and deadline (s 5(2)). The declaration fixes the temporal framework that will govern rights and duties under Part 3.6: a re-allocation period of five years beginning at the start of the 21st day after commencement, and a re-allocation deadline at the end of the day before the first anniversary of that start. Procedures in the Act that reference the re-allocation deadline or re-allocation period will operate using those dates. Parties must therefore observe those timing formulas when assessing rights under the Act (for example, when the Act requires actions by reference to the re-allocation deadline).

• Geographic delimitation of rights and duties by HCIS identifiers (s 5(3)). Rights to seek licences or obligations to respond to displacement or relicensing will be geographically delimited by the list of HCIS identifiers that form the named area. The instrument specifies how the named area is ascertained, by composite of HCIS-identified areas (s 5(3)). That means duties or protections that attach to the named area will apply if and only if a location falls within the composite HCIS coverage listed.

• Interpretative inclusion of boundary frequencies (s 4(2)). The instrument’s rule that a reference to a part of the spectrum includes frequencies greater than the lower frequency up to and including the higher frequency clarifies which frequencies at the band edge are encompassed. That interpretative rule assigns rights and duties in relation to the precise numerical range 3575-3700 MHz inclusive of 3700 MHz.

• Reliance on Act definitions (s 4 Note 1). The instrument imports the Act’s definitions for terms such as ACMA, re-allocation period, re-allocation deadline, spectrum, spectrum licence and spectrum re-allocation declaration. Parties’ rights and duties therefore depend on how those terms are defined and used in the Act, not on any new definitions in the instrument.

In operational terms, the declaration creates rights for parties to participate in whatever Part 3.6 processes the Act prescribes (application, allocation, reconfiguration, compensation, or other remedies under the Act), and places duties on affected parties to comply with those Part 3.6 processes and with ACMA decisions made pursuant to the Act. The instrument itself does not set procedural steps, commercial terms or compliance forms; it makes the frequency band and area subject to those existing statutory rules.

The instrument contains no standalone enforcement provisions, sanctions, infringement notices or penalty schedules. It is an enabling declaration that brings the specified spectrum and geographic area within Part 3.6 of the Act. Consequently, enforcement and penalties are those provided in the Radiocommunications Act 1992 and the subordinate instruments and processes that flow from it.

Given the instrument’s structure:

• There are no fines, criminal offences, or administrative penalties created or amended by the instrument text itself. Any penalty applicable to conduct in the band or area following re-allocation will be the penalty the Act supplies for unlicensed use, breaches of licence conditions, or failure to comply with ACMA directions.

• Enforcement powers remain those of ACMA and the Act. Because the instrument directs that re-allocation will proceed by issuing spectrum licences under Subdivision B Division 1 Part 3.2 (s 5(1)(a)), enforcement of licence conditions, suspension or cancellation of licences, and remedies for interference or unauthorised use will be exercised under the Act’s enforcement regime applicable to spectrum licences.

• The instrument's timing provisions (s 5(2)) will feed into any time-limited obligations the Act imposes in relation to the re-allocation deadline and re-allocation period. Parties that fail to observe Act-prescribed timelines may lose rights or be subject to consequences within the Act’s enforcement framework.

• Dispute resolution, review or merits review mechanisms are not set out in the instrument. Any review or challenge to decisions made under Part 3.6 or under the licensing Subdivision B will be governed by the Act’s review pathways, statutory appeal rights and any relevant administrative law avenue.

Because the instrument does not itself prescribe enforcement modalities, counsel and compliance advisers must look to the Radiocommunications Act 1992 (and related regulations and determinations) for the precise penalties, sanctioning procedures and available remedies. The instrument’s role is limited to naming the band and area subject to those existing enforcement mechanisms.

This declaration operates by reference to and within the framework of the Radiocommunications Act 1992. The instrument explicitly states it is made under subsection 153B(1) of that Act (cl 3) and directs re-allocation to proceed under Part 3.6 of the Act (s 5(1)). It also directs that re-allocation will be achieved by issuing spectrum licences under Subdivision B Division 1 Part 3.2 (s 5(1)(a)) and refers readers to section 153L of the Act. The instrument therefore has the following inter-legislative interactions:

• Primary interaction with the Radiocommunications Act 1992. The instrument does not create a standalone regulatory regime; it activates specific parts of the Act. Definitions, powers, procedures, remedies and penalties applicable to the re-allocation will be those contained in the Act. The instrument imports Act-defined terms by note (s 4 Note 1). Practitioners must consult Part 3.6 and Subdivision B of Division 1 Part 3.2 of the Act for the operative allocation and licensing rules.

• Referential dependence on ACMA’s administrative documents and spatial datasets. The instrument uses the Hierarchical Cell Identification Scheme (HCIS) as the naming convention for the geographic area (s 4(1) and s 5(3) notes). Those HCIS identifiers are components of the Australian Spectrum Map Grid 2012 and, according to the instrument’s notes, were available on the ACMA’s website when the instrument was made (s 5(3) notes). The legal delimitation of geographic boundaries is therefore bound to ACMA’s published mapping products. If those products are amended, the instrument’s practical effect depends on which version is authoritative; the instrument refers to the HCIS “as the document existed at the time this instrument was made” (s 4(1) HCIS definition), flagging version-specificity.

• No express interplay with other Commonwealth, State or Territory legislation is stated in the instrument. The text makes no explicit cross-references to environmental approvals, property regimes, telecommunications consumer protections, competition law or other statutes. Any interface with other laws will therefore arise as a secondary effect of licence outcomes under the Act (for example, planning approvals for base station construction still requiring compliance with local planning laws). Those interfaces are not addressed in this instrument; they remain matters to be resolved under the applicable statutory regimes.

• Administrative law and judicial review. The instrument does not create or limit access to judicial review. Decisions by ACMA under the Act that stem from this declaration will be amenable to the review mechanisms and judicial oversight set out in the Act and general administrative law. The declaration itself is an instrument under the Act, made under s 153B(1), and could theoretically be subject to challenge on the usual grounds applicable to delegated legislation; however the instrument contains no statement about ouster or limits on review.

In short, the instrument’s legal force is entirely channelled through the Radiocommunications Act 1992, with practical geographic application grounded in ACMA’s spatial mapping products. Practitioners must therefore read this declaration in conjunction with the Act’s substantive and procedural provisions and with ACMA’s published HCIS/ASMG resources.

The instrument as supplied contains its own naming and commencement provisions but records no subsequent amendments. The operative lines are:

• The instrument is titled “Radiocommunications (Spectrum Re-allocation,3.6 GHz Band for Perth) Declaration 2018” (cl 1). That establishes the originating instrument and year of enactment.

• Commencement is set to the day after registration (cl 2). The instrument therefore becomes effective the day following its registration date, which is not printed in the instrument text provided.

• The instrument does not include any amendment clauses, schedules of prior instruments it amends, or transitional amendments. It does not state it revokes, replaces or varies any earlier declaration.

• The instrument states the HCIS and ASMG resources “as the document existed at the time this instrument was made” (s 4(1) HCIS definition and s 5(3) Note 1), which fixes a reference point for the geographic identifiers. That language can have the effect of anchoring geographic definitions to the 2012 ASMG/HICS as it existed at the instrument’s making. The instrument contains no later modifications to that anchoring.

• There are no expressed consequential amendments to the Radiocommunications Act 1992 within the instrument text. The re-allocation is effected by operation of the Act’s Part 3.6, not by amendment to the Act contained in the instrument.

Because the instrument contains no schedule of amendments and no later variation, the amendment history within the instrument itself is static: it is a one-time declaration made under s 153B(1) with commencement as set out. To determine whether the declaration has been amended or revoked since the printed instrument, practitioners must consult the official legislative register for any subsequent instruments that vary or repeal it. The text supplied does not record any such variations.

The instrument contains no record of litigation, legal challenges, or judicial consideration. The text does not mention court proceedings, merits review applications, injunctions, or any disputes tied to this declaration. It is simply a statutory instrument that places a band and area under the Part 3.6 re-allocation regime.

Absent further materials, the instrument provides no details of:

• Any challenges to the declaration’s validity (for example, on administrative law grounds).
• Any interlocutory relief or injunctions that have been sought in relation to the declaration or ACMA decisions implementing it.
• Any case law that has interpreted the instrument’s scope, timing formulas, or HCIS-mapping consequences.

If litigation has occurred or is ongoing, that information is not recorded in the instrument text provided. Users requiring litigation history must consult court records, administrative review records, or legal databases to locate any proceedings that reference the declaration, Part 3.6 actions taken by ACMA in consequence of the declaration, or disputes over HCIS boundary definitions or re-allocation processes. The instrument itself contains no litigation history.

This instrument’s brevity produces several practical interpretative and compliance pitfalls that are implicit in its structure and wording. The following are concrete items to watch, each grounded in the instrument’s text:

• Timing calculation traps (s 5(2)). The re-allocation period begins “at the start of the 21st day after this instrument commences,” and the re-allocation deadline is “the end of the day before the first anniversary of the start of the re-allocation period” (s 5(2)(a)-(b)). Two issues arise: first, parties must calculate “the start of the 21st day after” commencement precisely; the instrument’s words require counting days from the commencement date (cl 2) and recognising the start of the specified day. Second, the deadline is phrased relative to that start-date, not relative to commencement, so miscounting the start will shift both the five-year period and the first-year deadline. The instrument does not give worked examples; miscalculation could cause missed application windows or deadlines under the Act.

• Dependence on the HCIS version in force when made (s 4(1) and s 5(3) notes). The instrument ties the named area to HCIS identifiers and expressly refers to the HCIS as used in the Australian Spectrum Map Grid 2012 “as the document existed at the time this instrument was made” (s 4(1) HCIS definition and s 5(3) Note 1). That anchoring means that later updates to ACMA’s mapping products are not necessarily authoritative for the instrument’s geographic boundaries; practitioners must obtain the HCIS version contemporaneous with the instrument. Relying on a later online map without confirming the version risks misidentifying whether a location falls within the named area.

• Complexity of composite HCIS listing (s 5(3) and table). The named area is to be “ascertained as the composite of the areas” listed in column 2 (s 5(3)). The table contains dozens of HCIS identifiers and multi-part cell ranges. Converting that list to a geographic footprint requires use of ACMA’s conversion tools or spatial datasets (s 5(3) Note 2). Manual transcription errors or mis-application of the conversion tool can lead to incorrect boundary assumptions.

• Edge-frequency inclusivity (s 4(2)). The instrument’s interpretative rule that a reference to a part of the spectrum includes frequencies greater than the lower frequency up to and including the higher frequency may be non-intuitive to some technical readers. It means 3700 MHz is included in the declared part of the spectrum. Systems operating at or very near band edges should confirm whether their operational frequencies fall within the inclusive top bound.

• No transitional or compensation details in the instrument. The declaration triggers Part 3.6 but does not itself provide transitional relief, compensation mechanisms or conversion processes for existing authorisations. A common operational “gotcha” is to assume the declaration contains transitional rules; it does not. Any displacement, compensation, or obligations will be found in the Act and ACMA instruments made under the Act.

• Reliance on ACMA procedures not set out here (s 5(1)(a)). The instrument specifies the route , issuance of spectrum licences under Subdivision B Division 1 Part 3.2 , but not the practical steps (application windows, auction rules, eligibility, fees). Parties must look to ACMA and the Act for those procedures; assuming a particular allocation format without checking ACMA announcements is risky.

• The declaration is geographically specific and not national (s 5(1)(b) and s 5(3) table). Some readers may assume a national 3.6 GHz reallocation; this instrument applies only to the named HCIS composite area labelled “Perth.” Verifying whether a site lies within the Perth composite is essential.

• Absence of amendment tracking in the text. The instrument references external ACMA materials and the registration date for commencement, but the instrument text provided contains no subsequent amendment entries. Users must confirm via the legislative register whether this declaration has been amended, superseded or repealed.

Each of these “gotchas” flows from how the instrument anchors legal effect to precise timing formulas, a specific dataset version, and the Act’s licensing machinery while itself remaining minimal. Addressing the gotchas requires cross-referencing ACMA spatial datasets, confirming the instrument’s registration date, and consulting the Radiocommunications Act 1992 for procedural detail.

Compliance is a two-stream exercise: (1) compliance with the declaration’s mechanics (timing and geographic identification) and (2) compliance with the Act’s processes once those mechanics are engaged. The instrument supplies the mechanics; the Act supplies the rules to follow. Practical steps derived from the instrument text are:

1. Confirm the commencement date and compute the relevant timelines (cl 2; s 5(2)). The instrument commences the day after registration. Parties should obtain the instrument’s registration date from the legislative register. From that commencement date, calculate the start of the 21st day after commencement (the start time of the re-allocation period). Then note two derived dates: the re-allocation period start, the re-allocation deadline (end of the day before the first anniversary of that start), and the five-year re-allocation period running from the start date (s 5(2)(a)-(b)). Keep clear records of these calculations since the Act’s processes will reference the re-allocation deadline and period.

2. Map operational sites to HCIS identifiers (s 5(3) and s 4(1)). The named area is specified as a composite of HCIS areas. Use ACMA’s ASMG/HCIS spatial datasets and conversion tools to convert the list of HCIS identifiers in the instrument’s table into GIS polygons and determine whether a particular site or operation lies within the named area. Pay attention to the instrument’s anchoring to the HCIS “as the document existed at the time this instrument was made” (s 4(1)); obtain the contemporaneous HCIS dataset or confirm ACMA’s guidance on the authoritative version.

3. Identify licences and authorisations tied to 3575-3700 MHz inclusive (s 4(2); s 5(1)). Determine whether your organisation holds spectrum licences, apparatus licences or other authorisations that operate within 3575-3700 MHz in the listed HCIS areas. Use the inclusive edge definition to confirm whether operations at 3700 MHz fall within scope (s 4(2)). Where an authorisation overlaps, check the Radiocommunications Act 1992 for the consequences of re-allocation for incumbents and any claims procedure, compensation entitlement, or required reconfiguration under Part 3.6.

4. Monitor ACMA notices and procedural instruments under the Act (s 5(1)(a)). Because the instrument declares the band subject to re-allocation by issuance of spectrum licences under Subdivision B of Division 1 of Part 3.2, ACMA will publish the operational details for allocation, including application forms, auction rules, technical conditions and fees. Practitioners must watch ACMA’s website and the Commonwealth Gazette for those instruments, timelines and application windows.

5. Prepare for administrative engagement. If you intend to apply for licences, assemble technical justifications, financial proposals and compliance documentation in advance of ACMA’s allocation processes. If you are a likely displaced incumbent, gather evidence of current use, coordinate with technical advisers on potential retuning, and prepare submissions that the Act permits (the instrument itself does not set such procedural detail; see Part 3.6).

6. Check for related statutory or regulatory requirements. The declaration does not pre-empt local planning, environmental, or other approvals that may be required for new base stations or network infrastructure. Ensure any licencing activities comply with the applicable laws in force outside the Radiocommunications Act.

7. Keep records of the HCIS mapping and versioning. To avoid boundary disputes, retain copies or extracts of the HCIS/ASMG mapping dataset that you relied upon together with the date of retrieval, since the instrument’s geographic definition is tied to the HCIS as it existed at the instrument’s making (s 4(1)).

8. Seek procedural clarity from ACMA where needed. If there is ambiguity about the start-of-day calculation, whether a particular site lies within a composite HCIS area, or the interaction of re-allocation deadlines with existing authorisations, seek formal guidance or a ruling from ACMA and place any clarifying correspondence on record.

9. Plan for technical edge cases. Because the instrument sets the spectrum part as inclusive of the top frequency (s 4(2)), plan for possible harmonisation issues where equipment operates very close to 3575 MHz or 3700 MHz and for cross-border interference issues at the geographic margins of the HCIS composite.

10. Verify the instrument’s current status. Before taking irreversible steps (investment in new equipment, surrendering existing authorisations), verify via the legislative register that the declaration remains in force and has not been amended, suspended or repealed.

These compliance steps are concrete actions implied by the declaration’s operative mechanics. They do not replace the need to consult the Radiocommunications Act 1992 for substantive licensing rules, remedies and penalties that will govern implementation following this declaration.
