Defence Determination, Conditions of service Amendment Determination 2020 (No. 3)

The Determination deploys a small set of recurring regulatory mechanisms to alter conditions of service. Those mechanisms, and the consequential main concepts that practitioners must track, are:

• Amendment-by-substitution and annex-level data updates. The instrument edits the 2016 Determination by substituting whole subsections (for example the new 16.2.4 and 16.2A.4 payment provisions), deleting an entire section (4.1.28 for Air Force higher duties) and replacing annex tables (for example Annex 12.3.B, Annex 13.3.A and Annex 16.A/16.B entries). These textual changes reframe eligibility algorithms, the mapping of posting location to an external "post index" and the numeric rates used in calculations (Schedule 2, Schedule 3, Schedule 4).

• Definitions drive entitlement. The new hardship/location provisions start with definitions (see substituted 16.2.3A and 16.2A.3A). Hardship location explicitly includes provisional hardship locations; qualifying location is either a hardship location or a location for which deployment allowance was paid; and qualifying period is the lesser of 28 continuous days or a period determined by the CDF. These definitional choices determine which service periods count toward entitlement, and give the CDF express discretion to set shorter qualifying periods (Schedule 3, 16.2.3A.c).

• Qualification threshold (28 days floor with CDF discretion). The instrument creates a standard 28-day qualifying period but allows the CDF to select a shorter period after considering criteria (the substituted text refers to the CDF needing to consider criteria under subsection 16.1.9.2). Practically this imports centralised decision discretion into otherwise formulaic allowance entitlement (Schedule 3, 16.2.3A.c.ii).

• Commencement and interruption rules. Payment begins the day the member entered the hardship/location location (16.2.4(1); 16.2A.4(1)), but is not payable during specified absences: long-term postings absent for 29 days or more (distinct rules if accompanied or unaccompanied), periods the member receives deployment allowance (subject to a dependent exception where the member is accompanied and at least one dependant remains), and temporary absences from a short-term duty overseas (Schedule 3, substituted 16.2.4(2) and 16.2A.4(2)).

• Cessation rules. Eligibility ends on the earlier of either the later of ceasing to be posted/deployed or stopping short-term duty in a qualifying location, or the day the location stops being a qualifying location. A note preserves continuity where a member moves immediately from one hardship location to another (16.2.6 and 16.2A.6 in substituted text) (Schedule 3).

• Dual Commonwealth benefit rule. The instrument specifies that the "dual Commonwealth benefit rule under section 16.1.5" applies to hardship and location allowances (16.2.3B(2) and 16.2A.3B(2)). That rule limits overlapping Commonwealth payments; it remains a keystone controlling multiple entitlements (Schedule 3).

• Delegation and administrative decision-making changes. Across many sections the Decision-maker title is changed to "Defence Housing Australia Regional Director" from "Housing Management Centre Manager" or "Housing Management Centre", shifting functions and decisions to Defence Housing Australia regional officers (Schedule 4, many items). For functions exercised by the CDF the text leaves CDF discretion explicit (e.g. qualifying period decision).

• Post index method and data-provider dependency. Section 12.3.14A as substituted ties the "post index" for a posting location to a "standard figure provided to Defence by a data service provider" for a location specified in Annex 12.3.B (with an exchange-rate variance note). The provision sets a floor of 100 in two circumstances: if the figure provided is less than 100 or if the post index location is not listed in Annex 12.3.B (12.3.14A(2)). Annex 12.3.B is replaced with a comprehensive mapped table of post index locations to the corresponding data-service location (Schedule 4, item 68-69).

• Tabular rate changes and currency entries. The instrument adds explicit country/currency/rate rows for Mali and South Korea in the relevant annexes (Schedule 2 and Schedule 4). It also standardises numeric placeholders ("nil" to "$0" or "0") across allowances and contributions (Schedule 4).

• Transitional and savings devices. Schedule 5 provides an entitlement to a top-up for qualifying service between 1 July 2017 and the Determination commencement; Schedule 6 preserves the old Air Force higher duties provision for existing recipients until their directions expire (Schedules 5 and 6).

These concepts are the building blocks for calculating eligibility, payment timing and amount, and for operational governance of housing and overseas allowances. The text uses cross-references extensively (for example to s 16.1.5, s 16.1.9.2, Annex mappings), which means the practical application requires reading the amended Determination as an integrated whole.

The Determination primarily affects Australian Defence Force members (members) and Defence administrative actors who manage pay and housing entitlements. More specifically:

• Members posted to hardship locations or deployed overseas. The substituted hardship and location allowance provisions (16.2.3A-16.2A.6 and related clauses) change who qualifies for those allowances, when payment commences and when it stops. Members who serve at qualifying locations (hardship locations, provisional hardship locations, or locations for which deployment allowance was paid) and who meet the qualifying period are directly affected (Schedule 3).

• Members who served overseas between 1 July 2017 and the commencement date. Schedule 5 creates a transitional top-up entitlement for members who performed 28 continuous days or more in combinations of deployment locations, hardship locations or provisional hardship locations during that window. These members are eligible to receive the difference between what they would have received under the specified comparator and what they actually received (Schedule 5).

• Air Force officers previously receiving a higher duties allowance for acting as a Commanding Officer. Schedule 1 removes the specific rate provision (s 4.1.28) for such acting appointments, but Schedule 6 preserves its continued application to officers who were in receipt immediately prior to commencement until the higher duties direction expires or is revoked. Accordingly, existing beneficiaries retain the old entitlement but future acting Commanding Officer appointments will be governed by the Determination as amended (Schedules 1 and 6).

• Members and families dealing with Defence Housing Australia (DHA). Numerous items throughout Schedule 4 change decision-making references from Housing Management Centre Manager/Housing Management Centre to Defence Housing Australia Regional Director or Defence Housing Australia Regional Office. Those changes shift which DHA actor is responsible for decisions about housing offers, rent allowance ceilings, audits, eligibility, house-sitters, release clauses in leases, resident child carer recognition and higher contribution scheme assessments (Schedule 4, many items). Members must notify the Defence Housing Australia Regional Director if they own, buy or sell a residential property in or near their posting location (substituted s 7.2.8).

• Payroll, finance and HR administrators. The instrument inserts new currency and numeric entries for Mali and South Korea into Annexes used to calculate travel and hardship/location allowances and standardises “nil” to explicit zeroes. Administrators must load new annex tables (Annex 13.3.A, Annex 12.3.B, Annex 16.A/16.B) and amend processing rules to reflect the new qualifying period logic, absence rules (29-day exclusion), and dual benefit rule application (Schedule 2, Schedule 3, Schedule 4).

• Central decision-makers. The CDF is given express discretion to determine a qualifying period shorter than 28 days (the qualifying-period rule is the lesser of 28 days or a period determined by the CDF), and is required to consider criteria under subsection 16.1.9.2 when making that determination. Defence organisational decision-makers (CDF and DHA Regional Directors) therefore have increased operational responsibility to apply criteria and maintain records of such determinations (Schedule 3 and substituted 16.2.3A.c).

• Dependants and members with special needs. Schedule 4 modifies the dependants definitions and clarifies that a person recognised under ss 1.3.84 or 1.3.85 is a dependant; it also provides that a dependant with special needs or a dependant recognised by the CDF is taken to "normally live with" the member even if unable to live with the member for a period (substituted ss 1.3.83.1, 1.3.87.3-4). These definitional changes affect how “accompanied” status and dependant-based allowances are applied.

• Defence contractors or outsourced providers supplying the post-index data. Section 12.3.14A ties the post index to a "standard figure provided to Defence by a data service provider" (Schedule 4). Suppliers and procurement/contract managers servicing that dataset are indirectly implicated because their output now directly feeds allowance calculations.

Groups not expressly mentioned in the Determination but affected operationally include compliance/audit teams (audit triggers changed by the new references to DHA Regional Director), decision-support teams who prepare CDF determinations, and legal advisors called upon to interpret transitional or ambiguous references (for example Schedule 5’s cross-reference to "Schedule 1" in a transitional provision that concerns hardship/location allowances , a drafting point to note).

The Determination sets out administrative duties for members and decision-makers, and correlative entitlement rights for members. The key statutory duties and rights that flow from the amended text are:

Member duties

• Notify Defence Housing Australia Regional Director of home ownership. Under the substituted s 7.2.8, a member must notify the Defence Housing Australia Regional Director if they own, buy or sell a residential property in or near their posting location. This is a clear administrative obligation placed on members (Schedule 4, item 13, substituted s 7.2.8).

• Provide evidence for rent and housing audits as required. Many rent allowance audit and evidence-related provisions now name Defence Housing Australia Regional Director as the decision-maker and recipient of evidence; members will be required to respond to audit requests addressed to that office (Schedule 4, multiple items, e.g. substituted references in 7.8.38.3-6, 7.8.39).

• Lodge approved forms. The Determination replaces a specific form reference (“lodge form AD291”) with “lodge the approved form” in one place (Schedule 4, item 66), signalling administrative obligations to use whatever form Defence subsequently approves.

Rights and entitlements for members

• Entitlement to hardship and location allowances where the qualifying conditions are met. A member who meets the qualifying period in one or more qualifying locations is eligible for hardship allowance (16.2.3B(1)) and location allowance (16.2A.3B(1)). These are rights to payment, but subject to the dual Commonwealth benefit rule under s 16.1.5 (each allowance expressly picks up that rule) and the payment exceptions in the substituted sections (Schedule 3).

• Payment commencement and non-payable periods. Payment entitlement commences on the day of entry to the hardship location (16.2.4(1); 16.2A.4(1)), but there are express non-payable periods, such as absences of 29 days or more while on long-term posting, periods on deployment allowance (except limited dependent-presence exception), and temporary absences during short-term duty overseas (16.2.4(2) and 16.2A.4(2)). These provisions specify both rights and the limits to those rights.

• Cessation of eligibility. Eligibility ends on the earlier of either the later of ceasing posted/deployed or stopping short-term duty in a qualifying location, or the day the location ceases to be a qualifying location (substituted 16.2.6 and 16.2A.6). Members who move immediately from one hardship location into another are specifically protected from immediate cessation by a Note to the substitution.

• Transitional top-up rights. Schedule 5 grants members who performed 28 continuous days or more in qualifying combinations of duty between 1 July 2017 and commencement of the Determination the right to a top-up amount equal to the difference between "the amount of hardship (or location) allowance the member would have received ... had Schedule 1 of this Determination applied" and the actual amount received. The transitional entitlement is expressed as an eligible amount and is triggered by historical service (Schedule 5, paras 1-3).

Decision-maker duties and discretions

• CDF discretion on qualifying period. The CDF may determine the qualifying period to be less than 28 continuous days, but the CDF must consider criteria under subsection 16.1.9.2 when doing so (16.2.3A.c.ii and note). That confers an operational duty on the CDF to apply and record decision criteria when exercising discretion (Schedule 3).

• DHA Regional Director decision functions. A wide range of decision functions previously exercised by Housing Management Centre Managers are transferred to the Defence Housing Australia Regional Director. Under the substituted and amended clauses, the DHA Regional Director now has the duty to consider members’ housing rejections, audit responses, rent ceiling increases, eligibility and related decisions (Schedule 4, multiple items, e.g. substituted text for s 7.6.57 and many others).

• Post-index determinations and data-provider dependence. The substituted s 12.3.14A obliges Defence to use a standard figure provided by a data service provider for post index locations and to apply an exchange-rate variance. It also creates an obligation to apply a post index of 100 in specified circumstances (12.3.14A(1)-(3); Schedule 4 item 68-69). That imposes a decision duty on administrators to maintain and apply that external data feed consistently.

Other procedural rights and limits

• Dual Commonwealth benefit rule applicability. The re-stated application of the dual Commonwealth benefit rule under s 16.1.5 to hardship and location allowances limits members’ rights to receive overlapping Commonwealth benefits concurrently (16.2.3B(2) and 16.2A.3B(2)).

• Savings right for certain Air Force officers. Section 4.1.28 continues to apply to officers who were already receiving higher duties allowance under that section immediately before commencement, until the direction to perform higher duties lapses (Schedule 6). That is a protected entitlement right for existing recipients.

Note on enforcement mechanics: The Determination is built around administrative entitlements and decision-making structures; it does not create new criminal offences or civil sanctions within the text supplied. Rights and duties are primarily operational (notification, provision of evidence, compliance with audit demand, adherence to absence thresholds), and enforcement is through administrative compliance and adjustment of pay rather than through specified penalties included in this Determination.

The text of the Determination does not introduce discrete criminal offences or new pecuniary penalties; enforcement is primarily administrative and operates through the structure of entitlement calculations, decision-making roles and payroll adjustments. The instrument uses standard administrative enforcement mechanisms found in conditions-of-service instruments:

• Administrative decision enforcement. Many provisions give named decision-makers authority to make determinations that affect entitlements. For example, the Defence Housing Australia Regional Director is the decision-maker for a host of housing-related matters (substituted provisions in Schedule 4). Compliance is enforced administratively by allowing or denying benefits, adjusting payments and exercising discretion on entitlement eligibility.

• Payroll deductions and contributions. The instrument standardises previously textual "nil" entries to explicit numeric zeros ("$0" or "0") in multiple contribution and allowance tables (Schedule 4, items 5, 18-36, 62-65, 76, 84-87). In practice this affects payroll systems and contribution calculations; enforcement is by automated payroll processing and administrative recovery where overpayments arise, though the Determination text itself does not prescribe a recovery mechanism in these specific amendments.

• Eligibility exclusions and suspension of payments. The substituted hardship/location payment provisions specify explicit non-payable periods (for example, absences of 29 days or more while on long-term posting, periods when the member receives deployment allowance unless accompanied and a dependant remains). These rules suspend or exclude payment during specified circumstances (substituted 16.2.4(2) and 16.2A.4(2)). Operationally, entitlement is stopped by payroll when conditions apply; this is the primary "penalty" for failing to meet continuous-presence requirements.

• Audit and documentation obligations. The numerous amendments changing audit and evidence roles to Defence Housing Australia Regional Director tighten the audit pathway: members who fail to respond to audit requests now face decisions from DHA Regional Director as the responsible officer (Schedule 4, multiple items concerning 7.8.38-7.8.39). While the Determination does not set out sanctions for failing to respond, failure will typically be enforced by disallowing or reducing entitlements or changing housing arrangements under the Determination’s administrative rules.

• Savings and transitional enforcement. Schedule 6 saves the continued application of the repealed Air Force higher duties section 4.1.28 for existing recipients until their directions expire or are revoked. This is an enforcement caveat: existing recipients continue to receive payments until the relevant direction ceases; the Determination therefore prevents immediate termination for those recipients (Schedule 6). Schedule 5 creates an enforceable transitional top-up entitlement (the entitlement is stated in monetary-difference terms), and administration must implement payments to eligible members.

What the Determination does not do (as expressed in the text):

• It does not create express criminal offences, fines or administrative penalty provisions within the amendment text. No new sanction framework is enumerated in the supplied amendments.

• It does not include a standalone appeal or merits-review mechanism within the amended clauses. The text specifies decision-makers (CDF, DHA Regional Director) but does not itself set out an internal review or external review pathway in the items reproduced.

Implementation and enforcement risk items for administrators

• Reliance on external data. The substituted s 12.3.14A ties allowance calculations to a data service provider’s standard figure for a post index location. Operational enforcement therefore depends on timely, reliable data from that provider; data errors or contract lapses could disrupt correct payment calculations (Schedule 4, item 68).

• Ambiguity in transitional reference. Schedule 5’s transitional entitlement refers to "had Schedule 1 of this Determination applied", though the hardship/location substantive changes appear in Schedule 3. That cross-reference creates an implementation and enforcement risk: payroll and entitlements teams will need to decide how to interpret the comparator and may require clarification or amendment from the responsible policy authority.

• Delegation reassignments. The transfer of many decision roles from a Housing Management Centre Manager to a Defence Housing Australia Regional Director changes the locus of enforcement decisions and may require updated delegations and resourced regional offices to execute new duties.

In short, enforcement is embedded in the eligibility rules, payroll processes and decision-maker actions; there are no new penalty provisions in the text supplied. Practical enforcement will therefore be by control of payment, documentation/audit processes and decision-making exercise by the CDF and Defence Housing Australia Regional Directors.

This Determination is a subordinate instrument made under section 58B of the Defence Act 1903 (s 3). It amends the Defence Determination 2016/19, Conditions of service, so its primary legal interactions are with:

• The Defence Act 1903. The Determination is an instrument under s 58B of that Act and therefore derives its enabling authority from the Defence Act. Decisions made under the amended Determination remain subject to the limits and administrative law principles that apply to decisions under the Defence Act and Commonwealth law more generally (instrument header and s 3).

• The base Defence Determination 2016/19. The instrument operates by amending and substituting provisions in the 2016 Determination; the two instruments must be read together. The amendment inserts new definitions, replaces tables and modifies decision-maker titles across the 2016 Determination. Operationally, the amended Determination displaces previous textual content where substituted but preserves continuity via savings clauses (e.g. Schedule 6).

• Internal Defence policy and administrative instruments. Several substituted provisions require or reference internal criteria and decision processes. For example, the qualifying period can be set by the CDF who "must consider the criteria under subsection 16.1.9.2" when doing so (substituted 16.2.3A.c.ii and 16.2A.3A.c.ii). That places the Determination in an interstitial relationship with internal Defence policy documents and administrative guidance that define how the CDF or delegated officers consider those criteria.

• Contracts and external data-provider arrangements. Section 12.3.14A ties the post index to a "standard figure provided to Defence by a data service provider" and directs that the figure be modified by exchange-rate variance from time to time (Schedule 4). That makes allowance calculations dependent on third-party data and therefore interacts with procurement contracts with the data service provider and any contractual terms governing data reliability, update frequency and intellectual property.

• Commonwealth remuneration and benefits rules, and potentially taxation law. The Determination revises allowances, contributions and benefit calculations. While it does not discuss taxation, any monetary allowances paid to members will interact practically with taxation law, social security or superannuation rules; those interactions are governed by other Commonwealth statutes and instruments. The Determination itself does not purport to change tax status; it changes amounts and eligibility for Defence-administered allowances.

• Administrative law remedies. The Determination confers decision-making powers on named actors (CDF, DHA Regional Directors). Those decisions will be subject to administrative law standards (for example, procedural fairness, reasonableness and review in applicable tribunals or courts) as they are decisions of the Executive. The Determination text does not itself set out an internal merits review; but decisions are susceptible to judicial review principles under the ADJR Act and related Commonwealth judicial review pathways.

• Interactions with other Defence determinations and instruments. The substituted dual Commonwealth benefit rule references section 16.1.5 in the base Determination. That rule governs overlapping Commonwealth entitlements. Users must trace cross-references within the Conditions of service Determination and any other Defence Determinations that prescribe deployment allowance rules, classification of hardship locations and related matters.

• Relationship with defence housing arrangements. Removing references to a Housing Management Centre Manager and replacing with Defence Housing Australia Regional Director relocates decision authority into Defence Housing Australia’s regional apparatus. Where housing is provided by DHA through contractual arrangements, the Determination’s reallocation of decision-making will interact with the contractual delegation of tasks to DHA and the internal governance arrangements between Defence and DHA.

In short, the Determination modifies only Defence’s internal statutory instrument; it operates within the legal architecture created by the Defence Act, other Defence Determinations and external contracts. It therefore interacts with internal policy documentation, procurement contracts with data providers, administrative law principles, and other Commonwealth statutes that govern pay, taxation and entitlements.

This instrument is an amending Determination to Defence Determination 2016/19. The key historical facts in the instrument itself are:

• Instrument identification and authority. Titled Defence Determination, Conditions of service Amendment Determination 2020 (No. 3), it is made under section 58B of the Defence Act 1903 (s 3). It is dated 4 March 2020 and commences on 5 March 2020 (ss 1-2).

• Structure of amendments. The instrument contains six Schedules. The Schedules make specific deletions, insertions and substitutions to the 2016 Determination. Schedules 1-4 effect substantive and editorial amendments; Schedule 5 contains transitional provisions; Schedule 6 contains savings for existing recipients of a now-deleted Air Force higher duties provision.

• Schedule 1: Air Force higher duties. Itemised changes remove Section 4.1.28 and associated references in Part 4.1 of the 2016 Determination (Schedule 1, items 1-3). Section 4.1.28 , Rate for higher duties , Air Force officer acting as a Commanding Officer , is omitted, and the exception referencing it is removed.

• Schedule 2: Overseas travel costs. Adds Mali entries to Annex 13.3.A (Part 1 and Part 2) immediately after existing item 46 (Schedule 2, items 1-2).

• Schedule 3: Overhauled hardship and location allowance rules. Replaces subsection 16.1.9.1 with a new provision that applies to decisions under specified subsections and substitutes new definitions and payment rules across Parts 16.2 and 16.2A (Schedule 3, items 1-5). The new scheme standardises qualifying location definitions, qualifying period calculation, payment commencement, non-payable periods and cessation rules.

• Schedule 4: Miscellaneous amendments. A long list of textual corrections, role substitutions, numeric standardisations, annex replacements (notably Annex 12.3.B) and new entries for South Korea in Annex 13.3.A and Annex 16.A/16.B (Schedule 4, items 1-92). The new s 12.3.14A defines the post index rule and Annex 12.3.B is replaced with a country-by-country mapping of post index locations to data service provider locations.

• Schedule 5: Transitional provision. Grants a top-up right for members who served 28 continuous days or more in qualifying combinations between 1 July 2017 and commencement. The transitional calculation compares amounts received with what "would have been received had Schedule 1 of this Determination applied" (Schedule 5, paras 1-3).

• Schedule 6: Savings. Preserves application of the deleted Air Force higher duties provision (section 4.1.28) to officers who were in receipt of higher duties allowance immediately prior to commencement, until the relevant direction expires or is revoked.

Notable drafting and implementation points from the amendment history embedded in the instrument:

• Reassignment of decision functions to Defence Housing Australia Regional Director is a pervasive editorial and governance change. It appears across dozens of clauses and annexes and is part of the instrument’s core operational redesign (Schedule 4).

• Data-driven indexing: s 12.3.14A and replacement Annex 12.3.B together convert post-index determinations into a data-provider dependent methodology, an amendment that operationalises an external inputs-based approach to some allowance calculations (Schedule 4).

• Transitional and savings mechanisms are used to mitigate the immediate impact of repeals on persons already receiving certain payments (Schedules 5 and 6).

The instrument text itself is the authoritative amendment history for these changes; there is no annexed explanatory memorandum in the text supplied. Any subsequent amending instruments, corrigenda or ministerial directions post-commencement would appear in later instruments and are not contained in this instrument.

The Determination text supplied does not record any litigation history, and it does not cite case law. The instrument is an administrative amendment to the Defence Determination 2016/19; it establishes administrative entitlements and decision-maker functions rather than private law obligations that commonly generate reported litigation notes within the instrument itself.

Practical implications for litigation risk and review that follow from the text:

• Administrative law review exposure. Decisions by the CDF, Defence Housing Australia Regional Directors, and other Defence decision-makers under the amended Determination will be subject to administrative law challenges (judicial review) if affected persons seek review on grounds such as procedural fairness, jurisdictional error, irrationality or unreasonableness. The Determination does not spell out review mechanisms; usual statutory judicial review avenues would therefore be the recourse for persons disputing a decision.

• Contract and procurement disputes. The post-indexing change in s 12.3.14A makes allowance calculations dependent on a data service provider. Failures or disputes about data provision could generate contractual claims between Defence and a data provider, which could indirectly affect members if data errors lead to incorrect payments. The Determination itself does not prescribe remedies for data errors.

• Transition and entitlements litigation risk. Schedule 5’s transitional top-up entitlement and its reference to "Schedule 1" (where the hardship/location substantive changes appear to be in Schedule 3) may produce interpretative disputes. Members or administrators who interpret the comparator differently could prompt internal disputes or, in edge cases, litigation if monetary entitlements are significant and unresolved administratively.

• Savings clause, unequal treatment claims. Schedule 6 preserves the old s 4.1.28 for existing Air Force officers who were in receipt of that allowance immediately prior to commencement, but removes it for future recipients. This creates a class of continuing recipients and non-recipients. Potential disputes about the scope of the savings clause or the definition of "immediately prior to the commencement" could arise, though the Determination’s wording is specific.

No judicial or tribunal decisions are cited in the instrument, and no litigation is recorded in the text. Any litigation arising from these amendments will be accessible in public law databases and must be traced outside this instrument.

The Determination contains multiple drafting choices and operational design features that create implementation traps and interpretation questions. Practitioners handling compliance or advising clients should note the following concrete "gotchas" grounded in the text:

• Transitional cross-reference oddity. Schedule 5 provides transitional top-ups for hardship and location allowance periods between 1 July 2017 and commencement, but the text calculates the top-up as the difference between "the amount ... had Schedule 1 of this Determination applied" and the amount actually received. The substantive hardship/location changes are contained in Schedule 3, not Schedule 1. This misreference can create ambiguity for payroll and legal teams implementing Schedule 5: which Schedule should be used as the comparator? The text, as printed, references Schedule 1, so administrators must seek policy clarification or legal advice to determine whether this is a drafting error or intended comparator (Schedule 5).

• Reliance on CDF discretion to shorten qualifying period. The qualifying period is defined as the lesser of 28 continuous days or a period determined by the CDF (16.2.3A.c; 16.2A.3A.c). That allows the CDF to set a shorter period for specific cases. Administrative practice will need to record the criteria and rationale, because members will be paid differently depending on that exercise of discretion. The Determination notes that the CDF must consider criteria under subsection 16.1.9.2, but it does not prescribe a process for publication of individual CDF determinations. This creates variability risk across postings.

• 29-day absence threshold. The substituted payment rules for hardship/location allowance create a specific absence-based non-payment rule: if a member on a long-term posting overseas is temporarily absent for 29 days or more, the allowance is not payable for that period (16.2.4(2)(a) and 16.2A.4(2)(a)). That bright-line 29-day rule requires careful monitoring of absences and raises issues where absences are fragmented or where dependants remain at location (different outcomes for accompanied vs unaccompanied members). Payroll systems must be able to identify and time-limit absences to 29 days to prevent under- or overpayment.

• Overlap with deployment allowance. The Determination disallows hardship or location allowance during periods when the member is receiving deployment allowance, unless the member is accompanied and at least one dependant remains at the hardship location (16.2.4(2)(b) and 16.2A.4(2)(b)). The note expressly includes days on deployment that contributed to the qualifying period. This creates a complex overlap rule where a member who used deployment days to qualify may later be excluded from payment while on deployment, subject to the accompanied/dependant exception. Administrators must reconcile accumulated qualifying days with subsequent deployment payments.

• Dual Commonwealth benefit rule. The newly emphasised application of the dual Commonwealth benefit rule (16.1.5) to hardship and location allowances keeps an overarching constraint on concurrent payments. Practitioners must trace all entitlements a member receives to ensure compliance and to avoid inadvertent double payments.

• Post-index floor at 100. The substituted s 12.3.14A sets the post index to the data provider’s figure except where the figure is less than 100 or the location is not listed in Annex 12.3.B, in which case the post index is 100 (12.3.14A(2)). That creates a floor effect: postings in lower-cost locations (as per data provider) will be given a post index of 100, not the true lower figure. That has distributional effects, possibly benefiting some postings relative to data provider reality. It also creates a discontinuity when a location is not listed in Annex 12.3.B.

• Wide swathe of decision-role transfers to DHA Regional Director. Replacing "Housing Management Centre Manager" with "Defence Housing Australia Regional Director" across many clauses centrally reassigns decision power. If DHA Regional Directors are not resourced or delegated appropriately, operational delays or inconsistent decision-making may occur. The amendments do not contain accompanying resourcing or delegation instruments; those will be internal matters.

• Replacement of "nil" with "0" or "$0". While superficially editorial, these changes may interact with automated systems that previously treated "nil" as a special indicator. Administrators need to ensure legacy systems interpret "$0" as intended and that the meaning is unchanged. Additionally, some table entries are changed from "N/A" to "-" (dash) or similar , these also require systems review.

• Savings protection limited to existing recipients. The savings clause in Schedule 6 explicitly protects only officers who were in receipt of the Air Force higher duties allowance immediately prior to commencement. Officers who take up similar roles after commencement will not receive the deleted rate. That may create inequities and possible industrial or grievance claims; however, legally the savings clause is narrowly framed and continues to apply until the direction to perform higher duties expires or is revoked.

• Dependants with special needs "normally living with" despite temporary inability to live with the member. Substituted s 1.3.87.4 takes a dependent with special needs or a dependent recognised by the CDF to "normally live with" the member even if the ground on which they are recognised means they are unable to live with the member for a period. That affects accompanied/unaccompanied status and dependent-based allowances and creates potential edge cases for members who have dependants temporarily resident elsewhere.

Each of these items is grounded in the text of the Determination and creates practical operational questions for payroll, housing and policy teams. Where ambiguity arises (notably Schedule 5’s cross-reference), practitioners should seek clarification from Defence policy owners or consider requesting an instrument correction.

For legal advisers, payroll staff, housing administrators and commanding officers implementing the Determination, compliance requires a set of concrete administrative steps and legal checks. Below are practical actions mapped to the instrument’s provisions:

1. Administrative ingestion and version control

   • Acquire and archive the amended text and ensure the base Defence Determination 2016/19 is updated with all substitutions and deletions from Schedules 1-6.
   • Ensure version control in the corporate legal/HR database so that records show the Determination effective date (5 March 2020) and the specific text of substituted clauses (notably 16.2.3A-16.2A.6, 12.3.14A and replaced Annexes).

2. Payroll and allowance systems changes

   • Load new Annex 13.3.A entries for Mali (Part 1 and Part 2 item 46A) and the South Korea additions (Annex 13.3.A parts for Brigadier/higher and Colonel/lower with items 73AA/73AB) exactly as inserted (Schedule 2 and Schedule 4). Use the exact currency codes and figures as provided.
   • Standardise numeric placeholders: change all "nil" entries to "$0" or "0" as substituted in the relevant tables. Confirm system interpretation of "$0" and "0" vs. "nil" to avoid processing errors (Schedule 4).
   • Implement the qualifying-period rule for hardship/location allowances: calculate the qualifying period as the lesser of 28 continuous days or a period determined by the CDF. Systems must accept a CDF-determined qualifying period override where recorded (substituted 16.2.3A.c; 16.2A.3A.c).
   • Implement rules to commence payment on the day the member enters a qualifying location and to suspend payment during the non-payable periods (29-day absence rule, deployment allowance overlap exceptions and short-term duty temporary absence) as set out in substituted 16.2.4 and 16.2A.4.
   • Ensure payroll can identify whether a member is accompanied or unaccompanied and whether dependants remain at a hardship location when a member is on deployment (the accompanied dependent exception). This requires HR records to track dependant residency status accurately.

3. Transitional payments and Schedule 5 implementation

   • Identify all members who performed 28 continuous days or more in the specified combinations of locations between 1 July 2017 and commencement. Extract their historical payment records.
   • Because Schedule 5 refers to "had Schedule 1 of this Determination applied", seek an early policy clarification from Defence People Policy to confirm whether the comparator should be the hardship/location rules in Schedule 3 or genuinely Schedule 1. Do not process top-ups until this interpretive issue is resolved, to avoid reprocessing and overpayment risk.
   • Once the comparator is confirmed, compute the difference amount for each eligible member and process top-up payments according to standard payroll procedures.

4. Decision-maker role and delegation updates

   • Update internal delegations and contact lists to reflect the reassignment of housing decision functions to Defence Housing Australia Regional Directors. Amend role descriptions, service level agreements with DHA and any memoranda of understanding to reflect these new responsibilities.
   • Ensure procedural documentation used by DHA Regional Directors is aligned to the amended Decision-making responsibilities (for example, procedure for considering member rejection of housing offers under substituted s 7.6.57).

5. Post index application and data-service arrangements

   • Implement the new post index methodology in s 12.3.14A. Ensure that the data service provider’s standard figure is available and integrated into the allowance-calculation pipeline, and that exchange-rate variance adjustments are applied as noted.
   • Implement the floor rule that sets the post index at 100 if the provider figure is below 100 or if the post index location is not listed in Annex 12.3.B.
   • Review the data-provider contract for service levels, update points of contact, data delivery schedules and responsibility for errors.

6. Audit, documentation and record-keeping

   • Maintain a documented audit trail for: CDF determinations shortening qualifying periods; DHA Regional Director decisions on housing; and any absences exceeding 29 days that suspend allowance payments. Save evidence required by the Determination (e.g. proof of dependant presence).
   • Update audit and evidence-handling workflows to reflect references to the DHA Regional Director in many clauses (Schedule 4).

7. Legal and policy review

   • Have legal counsel review Schedule 5’s comparator reference and the bounds of Schedule 6’s savings clause to ensure interpretations are defensible.
   • Review the interplay between the dual Commonwealth benefit rule (s 16.1.5) and other overlapping Defence payments to avoid inadvertent double payment.

8. Communication to members

   • Communicate changes to members who are likely affected: those on hardship postings, those who have been deployed between 1 July 2017 and commencement, Air Force officers acting in Commanding Officer positions, and members with housing arrangements managed through DHA. Provide specific guidance on: notification obligations for home ownership (substituted s 7.2.8), consequences of absences over 29 days, and how deployment allowance interacts with hardship/location allowances.

9. Systems testing

   • Before going live, run parallel testing over a sample of member records that would be impacted by the changes (cases involving deployment overlap, accompanied vs unaccompanied status, 28-day qualifying periods, recent Mali or South Korea postings) to validate the implementation.

10. Seek clarifications and corrections where necessary

• Identify any ambiguous references (notably Schedule 5) and seek prompt clarification from Defence People Policy and Employment Conditions. If the comparator in Schedule 5 was a typographical error, request a corrigendum or replacement instrument to avoid disputes and to standardise application.

By following the above steps, administrators and legal teams will operationalise the amended Determination while containing the principal implementation and legal risks that arise directly from the text.
