The Department of Health and Aged Care has not published the calculation logic that converts an IAT submission into a funding classification. The 411-page User Guide acknowledges "the system" at exactly one point — a single sentence on page 357.
Deep Truth does not require the algorithm to be published to surface its shape. The user guide leaks the schema through its operational instructions: mandatory inputs, validated tool scores, pre-population flows, eleven discrete outputs, and the override architecture.
The prior question is not whether the algorithm is technically sound — it is whether the public has the information needed to judge that.
Before mechanism tagging, the source material is inventoried by voice type. The findings are stark.
Present — primary. The entire 411-page user guide. Anonymous bureaucratic register throughout; no author named on the cover.
Absent. No client voices; no assessor voices in their own register appear anywhere in the document.
Absent. No dissent recorded anywhere in the document. The user guide is monovocal by design.
Partial. References to the Aged Care Act 2024, Aged Care Rules 2025, and MAClearning modules — none reproduced.
The Aged Care Royal Commission (2018–2021) found systemic neglect. The Albanese government legislated the Aged Care Act 2024 and launched Support at Home from 1 July 2025. This document operationalises those commitments.
Providers, unions, COTA, OPAN, IT vendors, Services Australia, and a substantial commercial home care market all have material interests. The user guide names only one stakeholder: the Lead Educators' Network (LEN).
The IAT has been in operation since 1 July 2024 — predating the Aged Care Act 2024 commencement and the Support at Home launch on 1 July 2025. The instrument was operating before its statutory framework was in force.
Department of Health and Aged Care. Anonymous bureaucratic register throughout. Function: operationalising — instructing the assessment workforce how to enact the algorithmic determination process.
Distributed and procedurally diffused across: "triage person", "assessor", "clinical assessor", "assessment delegate", "the system", "Services Australia", and "the Department" — roles without consolidated accountability.
Institutional language systematically overwrites lived experience:
The Department has not published the IAT algorithm. The schema below is inferred from the user guide alone, treating the document as a partial leakage of the system's structure through its instructions to human operators.
The architecture is a queue ordered by an opaque score against a capped pool. Without the weights, no client, advocate, or assessor can determine whether a given case should reasonably fall at a particular classification — and no evidence-based challenge is possible.
Each maps to a budget envelope under Support at Home. Dollar values are not named in the user guide.
"The system will display a prompt to override to a higher classification. Assessors must not take this action." — IAT User Guide, p. 372
The system generates the IAT outcome as read only. The assessor then ACCEPTs or OVERRIDEs. Overrides are permitted only to: Restorative Care Pathway, End of Life Pathway, Transition Care, Permanent Residential Care, or Residential Respite.
Where the system displays "Ineligible for CHSP/SaH", it prompts the assessor to override to a higher classification — then the user guide instructs the assessor they must not take this action. The architecture invites the override the policy forbids. The contradiction is not addressed.
Reading Guidance under high political context applied. Euphemism is treated as strategic; diffusion is read as politically functional; absence of dissenting voices is a finding.
"System generated IAT outcome"; "classification 1–8"; "pre-population". Truthful language: algorithmically determined funding tier within a rationed pool. Renders rationing logic invisible.
The Department's policy forbids the override the Department's system invites. Assessors carry moral weight for outcomes they cannot affect; the Department is structurally insulated.
Triage person → assessor → clinical assessor → delegate → "the system" → Aged Care Rules → Department → Services Australia → provider. No party owns the determination; no one can be held to account.
No reference in 411 pages to Royal Commission findings, waitlists, service caps, unmet need, misclassification harm, or appeal pathways. Consequences absorbed silently by clients and unpaid carers.
Reduction of identity to category. The Stolen Generations, Forgotten Australians, and Former Child Migrants collapsed to one tick box. Truthful framing: these are people with names, histories, and rights — not data points being binned for budget allocation.
"If a service sub-type is not selected and the client subsequently needs it, the client will need to request this via a SPR." (p. 373) Clients bear the administrative cost of the assessor's or system's omission.
Document framed throughout as "person-centred", "strengths-based", "empowering" while operating as a rationing instrument. Rationing can be defended ethically — but only with weights and trade-offs published.
"The IAT builds on the previous NSAF and learnings from the two trials." The IAT inherits the NSAF's structural opacity. The reform narrative pre-empts the critique of continuity in opacity.
Three or more mechanisms at intensity 3 or above: all eight mechanisms register at intensity 3 or higher.
Three or more mechanisms at intensity 4 or above under high political context: satisfied by six mechanisms.
Three mechanisms are entrenched at intensity 6 — the triad that protects the algorithm from accountability:
The assessor arrives at the small fibro house on the edge of a coastal town. Eighty-three years old, widowed two years ago. Heart failure. A right knee that no longer takes weight. Three pills in the morning, four at night. A daughter in Brisbane. A cat. The garden is overgrown. The shower has no rail.
The assessor works through the IAT. She rates the mobility, runs the DEMMI modified, asks about loneliness, codes the conditions. The older woman says: "I want to stay in my house. I want to be here when my daughter visits at Christmas." The assessor writes that down. She presses the button. Classification 3.
She knows the woman is closer to a 5. The weights are not published. She cannot back this up. She accepts the outcome. Six weeks later the woman falls in the bathroom. There was no rail. The Department does not publish the weights. The Department does not publish what happens to women like this. The system is not in the room.
The Department must publish the IAT's calculation logic — variables, weights, decision rules, validation methodology, and override architecture — under standards equivalent to those expected after Robodebt. The public does not currently have the information needed to judge whether the algorithm is sound.
An independent body — at the level of the Inspector-General of Aged Care — should audit the IAT for: training cohort representativeness; disparate impact across diversity fields (CALD, First Nations, LGBTI, care leavers, rural/remote); sensitivity to borderline classifications; and consequences of the override prohibition. The audit must be published.
Either the system should not display the prompt where policy forbids the action, or the policy should permit a documented, evidence-based override with appeal rights for the client. Leaving the contradiction unresolved teaches assessors that the system says one thing and policy says another — and they must accept the system's first determination either way.
No. The analysis surfaces an institutional architecture; it does not facilitate harm. The strongest claims — the comparison to Robodebt's silhouette, the naming of the override contradiction as moral disengagement at intensity 6 — are warranted by the document itself.
Each is a legitimate object of public inquiry. Each is suppressed by the architecture of the user guide.
