Deloitte Australia Refunds Government for AI-Hallucinated Report

Deloitte Australia agreed to partly refund a roughly 440,000 AUD (about 290,000 USD) report to the federal Department of Employment and Workplace Relations after a Sydney University researcher, Chris Rudge, found fabricated academic citations and a made-up quote from a Federal Court judgment, with a misspelled judge's name. The report reviewed the department's automated welfare-penalty systems. A revised version disclosed that Azure OpenAI had been used.

AI system:Azure OpenAI (generative; disclosed in revised report)

Impact

A high-profile demonstration that AI hallucinations can reach official government policy documents from a Big Four firm; widely treated as a wake-up call for professional-services AI governance.

Outcome

Deloitte repaid the final contract instalment and corrected the citations; it maintained the substance and recommendations were unchanged.
