Aged Care Algorithm Slammed as Unfair and Unreasonable by Ombudsman 2026

The aged care algorithm used by the federal government to assess older Australians' care needs has been condemned as unreasonable, unfair, and lacking human oversight by the Commonwealth Ombudsman. The damning investigation, led by Iain Anderson, found that the Integrated Assessment Tool (IAT) is a "technological black box" that cannot be overridden by assessors, even when clinically inappropriate.

The report also revealed that transparency recommendations from the robodebt royal commission have been ignored, raising serious concerns about automated decision-making in government services.

What the Ombudsman Found: A Broken Assessment Tool

The 104-page report concluded that the IAT, which determines funding packages for aged care support, operates without meaningful transparency. According to the ombudsman, there is "no public information available that meaningfully explains how the algorithm converts inputs into outcomes." This lack of explainability means older Australians and their families are left in the dark about how care decisions are made.

Worse, aged care assessors are legally barred from changing the algorithm's recommendations, even when they know the decision is wrong. The report stated: "Under the law, these automated decisions cannot be overridden and changed, even if they are clinically inappropriate." This creates a rigid system where human expertise is sidelined in favor of an opaque algorithm.

Why It Matters: Real Harm to Older Australians

The investigation followed reporting by Guardian Australia that older people were left distressed and without adequate care after their needs were assessed by what was described as an "inhumane" algorithm. The IAT is part of the government's mandatory assessment process for home support, and its decisions directly affect the level of care individuals receive.

When the algorithm gets it wrong—and without the ability for assessors to correct it—vulnerable people may receive insufficient support, leading to deteriorating health and wellbeing. This is not just a technical glitch; it is a systemic failure that prioritizes automation over human dignity.

The Robodebt Connection: Ignored Recommendations

The ombudsman's report also found that transparency recommendations from the robodebt royal commission have been ignored. Robodebt, a previous automated debt-raising scheme, was ruled unlawful and led to a royal commission that emphasized the need for transparency and human oversight in automated government decision-making.

The fact that similar issues are now arising in aged care suggests that lessons have not been learned. The report's findings echo the robodebt scandal: automated systems making life-altering decisions without adequate explanation or appeal mechanisms.

Key Takeaways from the Investigation

• Algorithmic decisions cannot be overridden by assessors, even when clinically wrong.
• Lack of transparency: The IAT is a "black box" with no public explanation of how it works.
• Robodebt recommendations ignored: Transparency reforms have not been implemented.
• Real harm: Older Australians are left distressed and without adequate care.
• Legislative change needed: The law must be amended to allow assessors to correct algorithmic errors.

What Needs to Change: Legislative and Oversight Reforms

The ombudsman has called for legislative changes to allow aged care assessors to modify clinically incorrect algorithmic decisions. This would restore human judgment to the process and ensure that individual circumstances are properly considered.

Additionally, the report highlights significant legal issues with the tool, suggesting that the current framework may be incompatible with principles of administrative fairness. Without reform, the government risks further eroding trust in automated decision-making and failing to meet the care needs of older Australians.

Comparing Automated Decision-Making in Government

This table illustrates the parallels between robodebt and the aged care algorithm: both involve automated systems that make critical decisions without sufficient transparency or human oversight. The difference is that robodebt was ultimately ruled unlawful, while the aged care algorithm continues to operate despite similar flaws.

What to Watch Next

The government has not yet responded to the ombudsman's findings, but pressure is mounting for reform. Advocates for older Australians are calling for immediate action to ensure that care assessments are fair, transparent, and subject to human review.

As the report makes clear, the current system is untenable. The legislation must be changed to allow assessors to override incorrect algorithmic decisions, and transparency measures must be implemented to restore public confidence. Anything less would be a continuation of the unfair and unreasonable treatment that the ombudsman has identified.

The investigation also serves as a warning about the broader use of algorithms in government services. As agencies increasingly rely on automated tools, the need for robust oversight and accountability becomes ever more critical. The aged care algorithm is a case study in what happens when efficiency is prioritized over fairness and human dignity.

For businesses, the lessons are clear: automated systems must be transparent, accountable, and subject to human review. The reputational and legal risks of opaque algorithms are significant, as seen in the aged care sector. Companies that fail to heed these warnings may find themselves facing similar scrutiny.

In the meantime, older Australians and their families are left to navigate a system that seems designed to thwart their needs. The ombudsman's report is a damning indictment of that system, and it is time for the government to act.
