One in five older Australians who challenged their aged-care funding had the decision overturned
Almost one-fifth of older Australians who contested their Support at Home funding allocation had the decision upgraded in their favour once a human reviewed it, according to departmental data that also reveals the government refused to release more current figures.
Of 757 requests for review of a Support at Home allocation as of 31 March, 141 resulted in a better outcome: eligibility for more services, a different or higher classification level, or a higher priority category. A further 177 produced no change, 304 were closed, and 135 were still in progress. (The Guardian, 19 August 2026)
The Department of Health and Ageing would not provide more recent data on how many people have contested their allocation under the integrated assessment tool, or IAT, which was introduced in November. (The Guardian, 19 August 2026)
The IAT is used across aged care to determine eligibility and classification for services, including Support at Home. An assessor asks an older person questions about their physical, social and personal circumstances. An algorithm then uses that data to allocate a level of support. The key detail: the algorithm's decision cannot be overridden by the assessor, even if they believe the older person has been given less support than they need. Think of it as a doctor being allowed to examine you but forbidden to write a prescription. (The Guardian, 19 August 2026)
The Commonwealth Ombudsman launched an investigation into the IAT in April. Assessors and older people have described the tool as "cruel" and "inhumane." The investigation is ongoing. (The Guardian, 19 August 2026)
Calls for help with aged care surged by 50% after the IAT's introduction, with critics describing it as a terrible system that overrides human and professional judgment. (The Guardian, 23 February 2026) The Guardian reported in April that there is no legal basis for the lack of human oversight in the algorithm, which frequently under-assesses levels of need. (The Guardian, 3 April 2026)
Greens senator Penny Allman-Payne, who is among several politicians calling for the government to reinstate human oversight, said the department's data does not capture the full scale of the problem because many older people do not know how to contest a decision. She said the IAT is under-assessing older people "far in excess" of what reassessment applications would suggest, and that many people would not be applying for reassessment at all. Those who do challenge often find the process fruitless, she argued, because the tool did not make a mistake but was working as designed when it denied them adequate care. She also said the IAT is systematically incapable of accurately determining need for people with cognitive issues, mental health conditions, and frailty. (The Guardian, 19 August 2026)
Mark Aitken, a nurse who has worked in aged care, blew the whistle in February on the absence of human oversight in home support decisions. He has since established Mascotte Aged Care Solutions, which provides independent guidance and advocacy for older adults and their families navigating the aged care system. Aitken said he has been supporting people to challenge their Support at Home allocations but warned that many older people do not have the luxury of time. (The Guardian, 19 August 2026)
The IAT system has left many people without adequate care, potentially forcing them into aged care homes sooner. (The Guardian, 19 August 2026)
A bill to restore human override to aged care assessments passed the Senate in July. (Australian Ageing Agenda, 2 July 2026) The Department of Health, for its part, describes the AN-ACC Assessment Tool as designed to be "robust and concise" to identify the level of an older person's needs in residential aged care. (Department of Health, 8 July 2026)
The broader context here matters. The 141 successful challenges out of 757 are not trivial. That is a near-one-in-five overturn rate on a system the government insists is working as designed. If a welfare algorithm produced that ratio on appeal, it would prompt immediate questions about whether the primary decision was sound. Aged care has not yet generated that level of political urgency, though the Ombudsman's investigation and the Senate's passage of a restoration bill suggest the pressure is building.
Allman-Payne's point about under-reporting cuts to the heart of the accountability problem. The 757 review requests represent only those who knew enough, or had enough support, to challenge. The IAT's design means an assessor can see the algorithm get it wrong in the room and be powerless to fix it. That is not a feature deficiency. It is a design choice, and one with no legal basis, according to The Guardian's April reporting. The people most likely to be misassessed, those with cognitive issues, mental health conditions, and frailty, are precisely the cohort least equipped to navigate a review process.
The department's refusal to provide more current data than 31 March is doing its own work. Five months of review data are missing from public scrutiny. That is a long time in a program that only launched in November. If the overturn rate has held steady or worsened, the government has a problem. If it has improved, there is no obvious reason to withhold the figures.
