What this is

In October 2025 Deloitte agreed to a partial refund after a A$440,000 report for the Australian government was found to contain AI-related errors, including fabricated citations. A professional-services case on verification, disclosure, and reputation — not a chatbot gimmick.

A 2025 government report with AI-related citation errors led to a partial refund — verification failed after delivery.

  • A$440,000 Department of Employment and Workplace Relations report.
  • Errors included references that did not stand up — consistent with generative hallucination.
  • Deloitte acknowledged AI assistance and agreed a partial refund (Guardian, Oct 2025).
  • The control that failed is the last-mile human check, not the existence of the model.

Next action: For the next board or client brief drafted with AI, require a named verifier for every citation and number.

What changes in how you lead

How decision rights, process, and ownership should change.

  • Verification is part of the deliverable — not a nice-to-have after send.
  • Disclose AI use in high-stakes client or regulator work when policy or contract requires it.
  • Purchasing should ask advisors how they check AI-assisted work.

Deep dive

The Guardian reported in October 2025 that Deloitte would provide a partial refund on a A$440,000 federal report after errors were identified, and that the firm acknowledged generative AI had been used in producing it.

Reporting described fabricated or incorrect references — the classic hallucination pattern — in a document that had already been delivered to government.

Leadership takeaways: treat citations, numbers, and legal references as must-verify; keep a human accountable for the last mile; write that standard into advisor SOWs.

The Guardian report is the primary public account of the refund and AI use.
