WA government seeks Deloitte reimbursement over university merger report with fabricated references and A$311m sum errors
Western Australia is seeking an expedited partial refund from Deloitte after its A$166,000 study on merging UWA, Curtin and Murdoch universities was found to contain fabricated references and scenario totals that miss the sum of their parts by up to A$311m.

Reach: not measured yet
The feasibility study contains two kinds of error. Some references were made up, and one link carries a ChatGPT tag. Separately, published scenario totals contradict their own components. In one scenario, A$514m plus A$145m is reported as A$399m. In another, A$396m plus A$116m is reported as A$823m. The state energy and economic diversification department has written to Deloitte to speed up cost recovery. [1] [7]
This is Deloitte's second AI-related refund dispute with an Australian government in about a year. In 2025, a A$440,000 federal welfare review drafted with Azure OpenAI GPT-4o was found to contain invented papers and a fabricated judicial quote. Deloitte then agreed to return the final instalment of its fee. [2] [3] [4]
The reviewed sources do not show whether the wrong totals came from AI or from people. Either way, both failures could have been caught before delivery by checking that every citation resolves and recomputing every total from its parts. Deloitte's disclosure says generative AI helped with research collation, synthesis and proofing, but it names no model. [1]
Deloitte and the WA government say the errors leave the modelling and findings unchanged. That is an assurance from the parties involved, not an independent check, and the underlying workings have not been released. Academics argue that a manually redone report and contract penalties tied to AI use may be needed. A separate reform business case will re-examine the merger data, and two of the three universities oppose the merger. [1] [6]

Implication: clients may demand disclosure of AI use, verification clauses and penalties, and practitioners should not sign off deliverables until figures are recomputed and citations resolve.
Executive brief
A A$166,000 Deloitte feasibility study on merging the University of Western Australia (UWA), Curtin and Murdoch universities has scenario totals that don't equal the sum of their own parts. In one scenario the gap is A$260m, in another A$311m. The report also contains AI-fabricated references, one of which carries a ChatGPT tag in its URL (Guardian). The WA government is now seeking "expedited" cost recovery. This is Deloitte's second AI-related refund dispute with an Australian government in roughly a year. The lesson for anyone using AI in their work is that simple arithmetic and citation checks would have caught both failures.
What changed and event timeline
Federal welfare report published
Deloitte's A$440,000 review for the Department of Employment and Workplace Relations (DEWR) was published. Sydney academic Chris Rudge later found invented papers and a fabricated quote attributed to a judge ().
7 October 2025: Revised report and partial refund
A corrected version added a note that Azure OpenAI GPT-4o was used in drafting. Deloitte agreed to return the final instalment of its fee (;).
- Early Oct 2026
Fake references flagged in WA report
Critics first spotted made-up references in the merger study, starting with a Reddit post, according to Times Higher Education as cited by.
Week before 18 October 2026: "AI slop" row
Opposition Leader Basil Zempilas said a student handing this in would get an "F". Minister Tony Buti said he was angry and would seek part of the fee back ().
More detail
Deloitte called the errors "minor".
Arithmetic errors exposed
Guardian Australia reported the A$260m and A$311m gaps and the ChatGPT-tagged link. The WA Department of Energy and Economic Diversification has written to Deloitte to speed up cost recovery ().
Capabilities and access
- WA report: Deloitte's disclosure says generative AI was used to "support the collation of research, synthesis of information and editorial proofing." It names no model or version.
- Federal report (2025): Azure OpenAI GPT-4o, licensed by DEWR (People Matters).

- WA report: Deloitte's disclosure says generative AI was used to "support the collation of research, synthesis of information and editorial proofing." It names no model or version. The ChatGPT URL tag shows only that at least one link came from that chatbot (Guardian).

Technical analysis for researchers and developers
- The fake citations are classic hallucinations. The sum errors are a different problem: published totals that contradict their own parts.
- What caused the arithmetic errors is undocumented. The reviewed sources contain no audit of the workflow.
- Practical implication: both failures can be caught automatically.

- Two kinds of failure. The fake citations are classic hallucinations. The sum errors are a different problem: published totals that contradict their own parts. In the Curtin/UWA high-cost scenario, 514 + 145 = 659, but the report says 399. In the low-cost three-university scenario, 396 + 116 = 512, but the report says 823 (Guardian).
- What caused the arithmetic errors is undocumented. The sources do not show whether AI produced the wrong totals or a person did. The reviewed sources contain no audit of the workflow.
- Practical implication: both failures can be caught automatically. Resolving every citation and URL, and recomputing every total from its components, would have flagged them before delivery.
- Repeatability: a corrected report has been promised. The underlying model and the calculation spreadsheets have not been released.
Claims and evidence
- The errors do not change the modelling or findings. This comes from the WA government ("we are advised") and from Deloitte (Guardian; ABC).
- The arithmetic gaps: these can be confirmed from the figures Guardian Australia quotes from the report.
- Fabricated references: reported by the AFR (as summarised by The Outpost) and by the Guardian.

- The errors do not change the modelling or findings. This comes from the WA government ("we are advised") and from Deloitte (Guardian; ABC). It has not been independently checked, and A$260–311m gaps make it hard to accept without the source workings.
- The arithmetic gaps: these can be confirmed from the figures Guardian Australia quotes from the report.
- Fabricated references: reported by the AFR (as summarised by The Outpost) and by the Guardian.
- Refund amount: not yet disclosed.
Context and prior work
- Deloitte said the corrections did not affect the report's "substantive content, findings and recommendations."
- Other firms: TNW notes that KPMG and PwC also faced criticism in 2025 over error-laden AI-written reports (TNW).
- Out-of-date facts: the WA report calls Curtin the "Curtin University of Technology," a name dropped in 2010 and changed by state law in 2017 (Guardian).

Limitations, safety and contested findings
- How serious the errors are is disputed. Buti first called them "typos" before saying he was angry.
- The merger itself is contested. Murdoch's vice-chancellor, Andrew Deeks, opposes it, and the ABC reports two of the three universities are against it (ABC).
- Deloitte did not respond to Guardian Australia's questions.

- How serious the errors are is disputed. Buti first called them "typos" before saying he was angry. Stephen Bartos (University of Canberra) argues the errors may be extensive enough to need a new report done by hand. Christian Downie (ANU) points to a lack of detail about how AI was actually used (Guardian).

- Deloitte did not respond to Guardian Australia's questions.
Business and practitioner implications
- Contracts: Downie urges governments to build incentives and penalties into consulting contracts that use AI.
- Liability: AI-assisted deliverables now carry refund risk. This is the second public refund dispute in about a year.
- Practice: treat AI output as a draft. Gate final reports on citation checks, recomputed figures and dated facts.

- Contracts: Downie urges governments to build incentives and penalties into consulting contracts that use AI. Expect clauses requiring detailed disclosure of AI use and verification of citations.

- Practice: treat AI output as a draft. Gate final reports on citation checks, recomputed figures and dated facts.
- Policy: the WA government says a separate university reform business case will re-examine all the data, so the Deloitte report's influence on the merger decision may shrink (Guardian).
