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

ACT government agencies and several federal bodies headquartered in Canberra are facing a crunch point over how they handle vast libraries of duplicate digital images — redundant photos, scanned documents, and archived visual records that have accumulated across shared drives, cloud platforms, and legacy systems over the past decade. The immediate question is not whether the problem exists, but what gets deleted, what gets kept, and who decides.

The issue has sharpened this year as storage costs have climbed and the ACT Government's digital records framework — managed under the Territory Records Act 2002 — comes under renewed scrutiny. Agencies that once treated cheap cloud storage as a reason to defer decisions are now confronting real budget pressure, and the backlog of unreviewed duplicate files has grown large enough that it can no longer be ignored before end-of-financial-year reporting cycles close.

Why Canberra Feels This Differently

Canberra's workforce is disproportionately employed in public administration, which means the city has a higher-than-average concentration of agencies that carry legal obligations around record retention. The Australian National Archives, based at the Rupert Murdoch Building in Parkes, sets the national framework for what Commonwealth agencies must preserve. The ACT Territory Records Office, operating out of Telstra House in the city, governs the parallel state-level obligations. When both layers apply to the same institution — as they do at places like the Australian National University on Acton Peninsula, or the National Portrait Gallery on King Edward Terrace — the question of which duplicate image can be discarded becomes genuinely complicated.

ANU, for example, runs a substantial institutional repository and has been expanding its digital humanities infrastructure through the Centre for Digital Humanities Research. Researchers working on long-term projects often accumulate multiple versions of the same archival image as working copies, backup copies, and published outputs. Without a clear governance decision on what counts as a "duplicate" versus a "version," those files cannot be legally destroyed — even when they are functionally identical.

The practical stakes are not trivial. Cloud storage for government and research institutions in Australia typically runs between $0.02 and $0.05 per gigabyte per month for standard tiers, according to published pricing from major providers. An agency holding even 50 terabytes of unreviewed image archives faces an ongoing bill in the tens of thousands of dollars annually — before staff time for any eventual remediation project is counted.

The Decisions That Cannot Wait

Three choices are converging over the second half of 2026. First, agencies need to determine whether automated deduplication tools — which identify byte-for-byte identical files — can be applied without triggering a formal disposal authority. The Territory Records Office has been working through updated guidance, but final advice had not been published as of this weekend.

Second, institutions like the National Library of Australia, whose Parkes Place West premises hold some of the country's most significant digitised collections, must decide whether human review is required before any automated process runs. Automated tools are fast and cheap; they are also indifferent to context, and a duplicate in a technical sense is not always a duplicate in a curatorial sense.

Third, and most immediately relevant to public servants in suburbs like Barton, Woden, and Civic who manage agency records day to day, there is the question of personal accountability. Under the Territory Records Act, improper destruction of a government record carries penalties. Waiting for formal guidance is defensible. Acting ahead of it is not.

The most likely near-term outcome is a series of agency-specific decisions rather than a single whole-of-government ruling. Departments with the most acute storage pressure will move first, probably through limited pilot programs using approved disposal authorities for defined classes of images. Larger institutions with more complex obligations — universities, national collecting bodies — will almost certainly wait for clearer guidance before touching anything. Public servants with questions about their own agency's position should, at minimum, document the current state of their holdings before the next budget cycle opens in August, so any future disposal decision has a defensible baseline to work from.
