Duplicate Images Are Costing Canberra Agencies Real Money. Here's What the Experts Say About Fixing It

Canberra's public sector has a storage problem hiding in plain sight. Across ACT government departments, federal agencies headquartered in Barton and Parkes, and the research collections at the Australian National University, duplicate digital images are quietly consuming server space, inflating licensing costs, and slowing down content workflows. The problem has a name—duplicate image proliferation—and the conversation about replacing those redundant files with properly catalogued, single-instance assets is now moving from IT helpdesks into budget discussions.

The timing matters. The ACT government's digital records modernisation program, which has drawn scrutiny at the Legislative Assembly level since early 2026, is driving agencies to audit their media libraries before the next financial year. Procurement teams are being asked to justify storage expenditure in a climate where every line item faces pressure. Duplicate imagery, once dismissed as a minor housekeeping issue, has become a measurable cost centre.

What the Specialists Are Saying

Digital asset management practitioners working with Commonwealth clients in the CBD precinct describe a consistent pattern: an organisation migrates content platforms—say, from an older intranet to a modern content management system—and in the process pulls across multiple copies of the same photographs, diagrams, and promotional graphics. Over a typical four-year content cycle, one mid-sized agency can accumulate tens of thousands of redundant image files, with storage bills that compound annually.

University of Canberra researchers attached to the Faculty of Arts and Design have been examining how cultural institutions catalogue visual collections, and their work points to metadata inconsistency as the primary driver of duplication. When staff upload an image without checking whether it already exists in the system—because the search function returns nothing under a different filename—another copy enters the archive. The fix is rarely glamorous: it involves hash-matching software to identify byte-identical files, followed by human review of near-duplicates where cropping or colour correction makes automated detection unreliable.

ANU's Scholarly Information Services team, based on the Acton campus, has publicly discussed the challenge of managing image rights across research publications. The core recommendation from information management professionals in that space is consistent: a duplicate replacement workflow should be paired with a controlled vocabulary for image tagging, so that future uploads are matched against existing assets before they are ingested.

The Local Procurement Angle

For ACT government agencies, the practical entry point is the whole-of-government procurement arrangements managed through Procurement ACT, which covers software licensing for digital asset management tools. Several tools capable of automated duplicate detection are already available under standing offer notices, meaning agencies do not need to run a full tender to access them. The issue, according to people who work in this space, is uptake—departments often licence the tools but do not build the internal workflows to act on what the software finds.

The Gungahlin and Belconnen service centres, which hold local-facing digital content for community programs, are among the locations where image libraries have grown fastest over the past three years, driven by COVID-era expansion of online service delivery. Those libraries were built quickly, and duplication rates in rapidly built archives tend to be higher than in collections that were developed with stricter ingestion rules from the start.

Storage costs for enterprise-grade government cloud infrastructure in Australia have not dropped as dramatically as consumer storage, and agencies paying per-gigabyte fees for duplicate files are, in effect, paying twice for the same asset. Exact figures vary by contract, but industry benchmarks published by the Australian Computer Society suggest that unmanaged digital asset libraries in mid-sized organisations can carry duplication rates of between 20 and 40 per cent by file count.

The practical advice from digital records specialists is sequential: run a hash-based audit first to identify exact duplicates and remove them, then address near-duplicates through a structured human review process, and finally implement a mandatory metadata check at the point of upload to prevent recurrence. For agencies operating within the ACT government's Whole of Government Digital Strategy, that last step should align with the shared taxonomy already in use across directorates. The window to get this right before the next budget cycle closes is narrowing—July is when the groundwork gets laid, and the savings, if the work is done properly, show up in the following year's storage invoices.
