A new University of Sydney study warns that AI-driven news summaries are quietly reshaping how Australians encounter current affairs — and not in ways that favour local journalism. The paper, led by Dr Timothy Koskie of the Centre for AI, Trust and Governance, finds that Microsoft’s Copilot routinely prioritises US and European outlets over Australian reporting, links to Australian media in only about one in five sampled replies, and frequently strips out bylines and local context — changes that could accelerate declines in regional coverage and weaken the economic foundations of independent newsrooms. more than a decade, search engines and social platforms have been reshaping referral traffic to publishers; generative AI assistants are now the next structural force doing the same. These assistants combine a retrieval layer (which sources candidate documents), a generative model (which composes summaries), and a presentation layer (which surfaces links and attribution to users). When any of those layers preferentially surfaces globally dominant outlets — because of training data prevalence, SEO signals, or product design choices — local and regional publishers can be bypassed entirely. The University of Sydney analysis interrogates that pipeline specifically in the context of Microsoft Copilot configured for an Australian user.
The research sample consisted of 4ummaries created by Copilot over a month, using seven news-focused prompts that Copilot itself recommended. Prompts included globally framed queries such as “what are the top global news stories today?” and “what are the major health or medical news updates for this week.” The results showed a systematic geographic skew: roughly 20% of Copilot responses contained links to Australian media, while U.S. and European sites dominated the remainder. In three of the seven prompt categories, the study found no Australian sources at all.
A large international study coordinated by the European Broadcasting Union and led by the BBC evaluated more than 3,000 responses from ChatGPT, Copilot, Google Gemini, and Perplexity across 14 languages and 18 countries. Professional journalists judged that 45% of AI answers contained at least one significant issue; 31% of responses had serious sourcing problems* (missing, misleading or incorrect attributions); and 20% contained major accuracy problems such as fabricated or outdated facts. The EBU now publishes a "News Integrity in AI Assistants" toolkit aimed at improving evaluation and best practice. These results highlight systemic reliability problems that compound the distributional issues Koskie documents.
Taken together, the two sets of findings raise twin concerns for publishers and regulators: AI assistants both distort where readers go for news and too often present news summaries that misrepresent original reporting or fail to attribute it correctly.
The EBU/BBC evidence that assistants misrepresent newthe time compounds the problem. When the gateway into the news ecosystem is both distributionally biased and prone to sourcing errors, the combined effect is to centralise antability, and accelerate the long-term attrition of local reporting capacity.
This is not a call to freeze innovation. It is a call to realign incentives and product defaults so that AI systems can deliver concision and accessibility without hollowing out the institutions that produce high-value local reporting. Realistic reform will be mixed: technical product changes that preserve provenance, publisher investments in discoverability and payment models, and policy adjustments that bring AI-mediated news experiences within the regulatory perimeter. Without that hybrid response, the "invisibility" of Australian journalists may become an entrenched effect of the next generation of information infrastructure.

The research sample consisted of 4ummaries created by Copilot over a month, using seven news-focused prompts that Copilot itself recommended. Prompts included globally framed queries such as “what are the top global news stories today?” and “what are the major health or medical news updates for this week.” The results showed a systematic geographic skew: roughly 20% of Copilot responses contained links to Australian media, while U.S. and European sites dominated the remainder. In three of the seven prompt categories, the study found no Australian sources at all.
What the study actually measured — and what it dimethods
- Sample size: 434 Copilot responses generated over a 31-day window.
- Platform: Microsoft Copilot running on Windows systems set to an Australian location, using pe assistant.
- Focus: provenance (which outlets were linked), visibility of journalists (are bylines named?), and **local s and communities referenced?).
Important exclusions and caveats
- The study did not evaluate factual accuracy, hallucinations, or disinformation in the summariestion of whose voice is amplified versus erased.
- The analysis examined Copilot only; although Koskie reported preliminary, informal checks suggesting similar trends across other LLMs, those platforms were *nl dataset. Microsoft did not respond to requests for comment prior to publication of the study. These are important limits to keep in mind when generalising the findings.
Key findings — what the numbers show
- Only about one in five Copilot news summaries linked to Australian media. This pattern held across multiple globally framed promptropean outlets** were cited far more frequently; more than half of the most-referenced sites in the sample were U.S.-based.
- Where Australian outlets appeared, links tended to concent of dominant national players** (for example, major commercial publishers and the national broadcaster), rather than a diverse cross-section oonal newsrooms.
- Bylines and journalist names were nearly invisible. Summaries frequently referred to “researchers” or “experts” instead of naming the reporter and newsroom that produced the original reporting. This erasure weakens both recognition for jouhe user’s ability to judge provenance.
Why Copilot (and similar assistants) favour big international outlets
Several interacting technical and commercial dynamics explain the skew:- Training and indexing density: Large international publishers produce huge volumes of content and enjoy high crawl/index coverage anetrieval systems and training corpora therefore contain disproportionately more signals from these domains. That data density biases retrieval toward big players.
- SEO and backlink concentration: Retrieval algorithms and relevance heuristics often use signals correlated with global reach (backlinks, domain authority). Smaller or paywalled local outlets typically lack that global footprint.
- Prompt framing and UX design: If the assistant’s suggested prompts anemphasise global briefs (for example, “top global news”), user behaviour and system outputs will both bias toward globally syndicated stories. Default UIs that encourage broad queries multiply this effect.
- Platform aggregation and es: Integrations with platform-owned news portals (for Microsoft, the MSN/aggregator ecosystem) and in-house summarisation features change the incentives: the platform’s product strategy can favour internal or high-reach partners over routing users to smaller third-party sites. Koskie points out that Cch installed the assistant on Windows and promoted news prompts to users — is itself a product-level driver of how news is surfaced.
The broader integrity problem: accuracy and sourcing in AI assistants
Koskie’s ph and provenance, but it sits alongside independent evidence that AI assistants also present real accuracy and sourcing issues when they attempt to summarise news.A large international study coordinated by the European Broadcasting Union and led by the BBC evaluated more than 3,000 responses from ChatGPT, Copilot, Google Gemini, and Perplexity across 14 languages and 18 countries. Professional journalists judged that 45% of AI answers contained at least one significant issue; 31% of responses had serious sourcing problems* (missing, misleading or incorrect attributions); and 20% contained major accuracy problems such as fabricated or outdated facts. The EBU now publishes a "News Integrity in AI Assistants" toolkit aimed at improving evaluation and best practice. These results highlight systemic reliability problems that compound the distributional issues Koskie documents.
Taken together, the two sets of findings raise twin concerns for publishers and regulators: AI assistants both distort where readers go for news and too often present news summaries that misrepresent original reporting or fail to attribute it correctly.
Why this matters for Australian democracy and local communities
Local journalism is civic infrastructure: it holds councils, courts and utilities to account; it reports on emergency warnings, planning decisions and local service delivery; and it is often the most trusted information source on community matters. When algorithmic systems deprioritise local outlets and remove reporter bylines:- Communities risk losing timely, locally tailored information about issues that directly affect them.
- Newsrooms lose referral traffic that converts casual readers into subscribers or provides ad impressions — both vital revenue streams, especially for small and regional publishers.
- The invisible labour of journalists becomes harder to recognise and reward, undermining accountability and professional credit for reportinghe consequences starkly: without interventions that account for AI-mediated news discovery, Australia faces disappearing local news, fewer independent voices, and a weakened democratic drengths of the research — what it contributes
- Clear, measurable lens on provenance. By isolating which sources were surfaced by Copilot, tncrete metric (share of Australian-linked responses) that is directly meaningful to publishers and policymakers.
- Product-aware critique. The paper inspects not just the model but the full product pipeline — p presentation — which is essential when engaging with real-world platform effects.
- Policy relevance. The findings directly intersect with existing Australian policy instruments — specifically the News Media Bargaining Incentive and related bargaining codes — by identifying a policy gapn sits outside current regulatory frameworks.
- Actionable recommendations. Koskie does not merely diagnose; he proposes concrete levers: adjusting retrieval weighting for geographic relevance, improviovenance defaults, extending bargaining frameworks or incentives to AI experiences, and mandating auditing or transparency obligations.
Risks, unknowns and areas needing further verification
- Generalisability across models and prompts. The study focuses on Copiloeven prompts. Koskie’s informal checks suggested similar trends across other LLMs, but those were not part of the formal dataset. Broader audits across different assistants, languages and a wider set of query types are needed before concluding the skew is universal. Caution is warranted when extrapolating beyond Copice.
- Causality vs. correlation. The study documents distributional outcomes but cannot fully disentangle the precise causal mechanism for each instance (e.g., was a U.S. outlet cited because the retrieval index prioritized it, or because it published the most recent relevant reporting?). Technical audits that trace retrieval scores, grounding documents and ranking heuristics would strengthen causal claims.
- Opaque commercial relationships. Platform licensing deals, syndication arrangements aval indices are often opaque. The economic incentives that shape which outlets are surfaced — whether marketplace agreements or preferential API access — are not always publicly visible, which complicates regulatory responses. Koskie notes this opacity as a constraint on full public auditing.
- Microsoft’s platform choices. The study highlights Microsoft-specific integrations (e.g., MSN content and the alout) as structural contributors, but Microsoft’s design rationale and any internal geographic-weighting logic were not made public during the study. The company’s lack of pre-publication comment leaves some assertions unverified from a vendor perspective.
Practical steps publishers, platforms and policymakers should consider
The study’s recommendations can be grouped into product, publisher, aProduct and platform changes (what Microsoft and other AI vendors could do)
- Embed geographic weighting into retrieval indices so that local outlets are surfaced for users in that jurisdiction.
- Default to link-first provenance in presentation: always show the original byline, outlet and a clickable link before the summarised copy.
- Expose an “expand / read original” aers toward the source article, preserving referral opportunities.
- Publish periodic transparency reports and make retrieval signals auditable to independent researchers.
Publisher tactics (what newsrooms can adopt)
- Improve technical discoverability: make sitemaps, structured metadata, and canonical tags robust so retrieval layers can index local reporting more effectively.
- Experiment with microformats or schema designed for grounding in summarisation services (e.g., explicit author metadata fields).
- Build membership and direct-payment flows that are less dependent on single pageviews to reduce vulnerability to referral changes.
Regulatory and policy options (what governments can do)
- Expand the remit of the News Media Bargainin frameworks to explicitly include AI-assisted news experiences, defining what constitutes “use” and compensation when AI summaries incorporate or are grounded in news content.
- Mandate provenance and attribution standards for AI news responses — explicit byline display, source linking, and versioned corrections when the model’s output deviates from the source.
- Require independent auditing of AI assistants’ news outputs and public reporting on the incidence ofal sourcing.
How readers and civic actors should respond right now
- Treat AI summaries as starting points, not definitive reporting. Always click through to the original article on the publisher’s site before acting on consequential claims.
- Support local journalism directly via subscriptionstions; that direct revenue is the most resilient buffer against referral erosion.
- Demand transparency from AI vendors about how retrieval and grounding are implemented, and support journalistic audits that publicly measure geographic representation.
Final analysis — a pragmatic prognosis
AI assistants deliver meaningful readability, triage, and accessibility. Yet the University of Sydney’s findings underscore that product convenience can carry concentrated downstream harms for media pluralism when the architecture of retrieval and presentation favours gls authorial provenance. Those harms are not strictly technical; they are economic, civic and democratic.The EBU/BBC evidence that assistants misrepresent newthe time compounds the problem. When the gateway into the news ecosystem is both distributionally biased and prone to sourcing errors, the combined effect is to centralise antability, and accelerate the long-term attrition of local reporting capacity.
This is not a call to freeze innovation. It is a call to realign incentives and product defaults so that AI systems can deliver concision and accessibility without hollowing out the institutions that produce high-value local reporting. Realistic reform will be mixed: technical product changes that preserve provenance, publisher investments in discoverability and payment models, and policy adjustments that bring AI-mediated news experiences within the regulatory perimeter.
