Canberra's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

The ACT government's digital asset libraries have a duplicate image problem, and nobody has found a clean way out of it yet. Across agencies including Transport Canberra, the ACT Public Service directorate system, and the Australian National University's digital collections, administrators are sitting on vast repositories where the same photographs, diagrams and graphics have been stored multiple times under different file names — inflating storage costs, complicating Freedom of Information requests and creating real risk that outdated images circulate in public communications.

The issue has sharpened in 2026 for a specific reason. The ACT government's whole-of-government cloud migration program, which has been rolling through directorates since late 2024, is now hitting the content layer. When agencies migrate from legacy on-premise servers to cloud environments, duplicate files don't just move — they multiply. Storage that once cost a fixed sunk amount suddenly attracts ongoing per-gigabyte charges, making the invisible problem financially visible for the first time.

Where the Pressure Is Building

Two locations illustrate the scale. Transport Canberra, which manages light rail communications for both the existing Gungahlin line and the contested Stage 2 extension toward Woden, maintains promotional and operational image libraries that have grown substantially since the network opened. Every media release, every social post, every Board presentation draws on those libraries — and without a deduplication protocol, images accumulate in parallel folders held by communications staff, project managers and external contractors simultaneously.

At the ANU's Chifley Library precinct on Acton Peninsula, digital archivists working under the university's Scholarly Communications team face a related but distinct version of the challenge. Research image datasets submitted alongside published papers are frequently ingested multiple times as different stages of peer review create separate submission records. The university's open-access repository, which crossed 50,000 items in 2025 according to ANU library annual reporting, has flagged deduplication as a priority for its 2026-27 operational planning cycle.

The ACT's whole-of-government digital records framework, administered under the Territory Records Act 2002, technically requires agencies to maintain accurate and non-redundant records — but the Act predates cloud-native storage architectures by more than two decades, and enforcement guidance has not been updated to address automated deduplication tools or AI-assisted image matching. That regulatory gap is now being examined by the ACT Ombudsman's office as part of a broader records management review flagged in its 2025-26 work program.

The Decisions That Will Define the Outcome

Three specific choices will determine how this gets resolved — or doesn't — over the next twelve months.

First, agencies must decide whether to run deduplication retroactively across existing archives or apply it only to new ingestions from a fixed cut-off date. The retroactive option is more thorough but risks deleting files that different users consider distinct records despite being pixel-identical. The forward-only option is safer legally but leaves the existing mess untouched.

Second, the ACT Chief Digital Officer's office needs to decide whether to mandate a single deduplication standard across all directorates or let each agency procure its own solution. Mandating a standard is administratively efficient but complex to enforce given the different content management systems in use — the planning directorate runs a different document environment from Health, for instance, which operates partly on systems linked to Canberra Health Services at the Woden campus.

Third, and most consequentially for public servants working in Barton and Civic, is the question of what happens to images flagged as duplicates that were used in official published materials. Under records law, those files may need to be retained even after a preferred master copy is designated — meaning deduplication may reduce active clutter without actually reducing archival storage obligations.

The ACT government has indicated through its 2026-27 Budget process — which allocated funding for digital transformation across the public service — that further guidance is coming. Agencies expecting clear direction should watch for updated records management policy from the Territory Records Office, with consultation on draft standards expected to open before the end of September 2026. For institutions like ANU and the University of Canberra's Bruce campus, which operate outside ACT government jurisdiction but share infrastructure partnerships, the federal government's own digital records review under the National Archives of Australia will run in parallel and may set a higher bar.
