ACT government agencies collectively manage tens of thousands of digital image files across their content management systems, and a significant portion of those files are duplicates — the same photograph stored two, three, sometimes a dozen times under different filenames across different departmental servers. The scale of the redundancy is not trivial. Industry benchmarks from digital asset management research consistently put duplicate image rates in large public sector organisations at between 20 and 35 percent of total image libraries.
The timing matters. The ACT government is mid-way through a broader digital transformation program, and several agencies headquartered along London Circuit and Edinburgh Avenue in Civic are actively auditing their content repositories ahead of planned platform migrations scheduled through 2026 and into 2027. Finding and replacing duplicate images — or consolidating them into single authoritative source files — is now a line item in those migration budgets, not an afterthought.
What Duplication Actually Costs
Storage costs are the obvious number, but they are not the biggest one. Cloud storage on government-grade platforms typically runs between $0.02 and $0.05 per gigabyte per month for standard tiers. A library of 50,000 images averaging 8 megabytes each occupies roughly 400 gigabytes — manageable cost on its own. But when 30 percent of those files are duplicates, agencies are also paying for the staff time to tag, license-check, and audit redundant assets every time a communications team publishes new material.
The Australian National University's Digital Collections team, which manages one of the largest academic image repositories in the ACT, estimated in internal planning documents released under FOI in 2025 that manual deduplication of a mid-sized archive of around 80,000 files took three full-time staff approximately six weeks. That figure has become a reference point for ACT Shared Services, which provides IT infrastructure to multiple directorates, as it models the resource requirements for its own deduplication projects.
The University of Canberra's library and information science faculty has also contributed to the conversation. Research published through UC in late 2024 found that public sector organisations with no automated deduplication tooling spent an average of 14 percent more per content campaign on image sourcing — because staff, unable to locate existing approved assets quickly, simply licensed new photographs rather than searching fragmented internal libraries.
The Local Push Toward Automated Solutions
ACT government digital teams are not waiting for a territory-wide mandate. The Environment, Planning and Sustainable Development Directorate, based on Callam Street in Woden, began trialling perceptual hashing tools — software that identifies visually identical or near-identical images regardless of filename or file format — in the first quarter of 2026. Perceptual hashing compares images algorithmically and can process a library of 100,000 files in under four hours on standard server hardware, compared to weeks of manual review.
Transport Canberra and City Services, which maintains extensive photographic records of infrastructure across Gungahlin, Belconnen, and the inner north, flagged duplicate image management as a specific workflow challenge in its 2025-26 operational plan. The directorate's asset photography library alone spans construction progress records, community consultation imagery, and light rail corridor documentation — categories prone to duplication when multiple project teams photograph the same site independently.
The practical case for action is straightforward. Agencies that have completed even partial deduplication exercises report measurable time savings at the content production stage. Fewer files to search means faster turnaround for communications teams. Cleaner libraries also reduce the risk of publishing outdated or superseded imagery — a compliance issue when government publications require current, accurate representations of infrastructure or services.
For public servants and contractors working across ACT directorates, the immediate advice from digital asset specialists is consistent: before any platform migration, run a baseline audit using hash-comparison tools to establish the true duplication rate. That number — whatever it turns out to be — is the starting point for every downstream decision about storage allocation, licensing review, and staff time. Getting it wrong at the audit stage compounds every cost that follows.
