Deloitte Faces Refund Demand After AI-Generated Errors Plague $166,000 WA University Report

Deloitte Under Fire for Flawed University Report

The WA government has demanded an expedited reimbursement from Deloitte after discovering significant AI-generated errors in a $166,000 feasibility study on merging three Perth universities1

. The flawed university report, which examined potential mergers between the University of Western Australia, Curtin University, and Murdoch University, contained AI-generated fake references to sources that do not exist and incorrect cost totals running into hundreds of millions of dollars. A government spokesperson told Guardian Australia the state was "extremely disappointed" and had written to Deloitte to speed up the Deloitte refund process2

Major Cost Discrepancies Undermine Credibility

The cost discrepancies in the report are staggering. Under a high-cost scenario for a Curtin and UWA merger, the report calculated total costs to day one at $514m and post day one costs over five years at $145m. These two figures total $659m, yet the report stated $399m—a $260m discrepancy2

. In another scenario examining a low-cost merger between all three universities, costs totaling $512m were incorrectly reported as $823m—a $311m error2

2

. Prof Stephen Bartos, an expert in public sector governance at the University of Canberra, said the errors are so extensive that a new report may be needed, noting that "any errors in a report like this, especially on something controversial like a university merger, discredits the report"2

AI Hallucinations and Fabricated Sources

Deloitte acknowledged in the report that it used generative AI for research to "support the collation of research, synthesis of information and editorial proofing"2

2

. Critics first flagged the AI-generated fake references in early October through a Reddit post1

1

. Guardian Australia discovered that one reference to a World Health Organisation report contained a ChatGPT metadata tag on the URL, indicating the link was directly sourced from the chatbot2

2

. These AI hallucinations represent a fundamental failure in quality control for consulting work of this magnitude. Initially, Deloitte dismissed these as "minor errors," though the WA government instructed the firm to fix and reissue the report1

Transparency Concerns and Risks of AI Tools

The incident highlights growing concerns about transparency in AI use within professional consulting. Prof Christian Downie from the Australian National University emphasized the need for much more detail about how AI tools are being deployed in report writing processes2

2

. "If they're going to use it for data collection and if there's concerns about the data, then that needs to be detailed in the report," Downie said2

2

. The risks of AI tools become particularly acute when firms lack proper oversight mechanisms. The report also repeatedly referred to Curtin University as "Curtin University of Technology"—a name the institution abandoned in 2010 and officially changed under state parliament act in 20172

Pattern of AI-Related Report Errors

This AI-related report error is not an isolated incident for Deloitte. In 2025, the firm agreed to partially refund Australia's federal government for a $440,000 report that also contained AI-generated errors1

1

. Rival consulting firms KPMG and PwC have faced similar problems with AI-written reports this year1

1

. This pattern suggests systemic issues across the consulting industry regarding the deployment of generative AI for research without adequate safeguards. Prof Downie argued that all levels of government need to recalibrate their contractual arrangements when outsourcing work to consulting firms "to ensure that the proper incentives and penalties are in place"2

Implications for University Merger Decision

Despite the errors, the WA government stated it had been advised the mistakes do not affect the report's modeling or findings, though Deloitte will correct them and reissue the report1

1

. WA tertiary education minister Tony Buti initially described the errors as "typos" before later expressing anger and disappointment with Deloitte2

2

. The government has characterized the university merger as a "once-in-a-generation" opportunity, with Buti stating he wants to commit "if the business case stacks up"2

2

. However, the proposal faces opposition from Murdoch University, whose vice-chancellor Prof Andrew Deek criticized the report and penned an op-ed arguing against the merger2

2

. The Department of Energy and Economic Diversification has indicated that all available data will be interrogated by the university reform business case moving forward2
