Canberra Agencies Race to Fix Duplicate Image Problem as Digital Archives Hit a Critical Threshold This Week

A July 1 compliance deadline has pushed several Canberra-based federal agencies into an active cleanup of duplicate and redundant image files sitting inside their digital asset management systems, with at least two major institutions confirming they are now running automated deduplication tools across archives that have grown unchecked for more than a decade.

The issue matters now because the Australian Government's Digital Transformation Agency updated its Digital Sourcing Framework guidance in the first half of this year, placing stricter obligations on Commonwealth entities to audit and rationalise their stored media. Duplicate images — the same photograph or graphic filed multiple times under different names or metadata tags — bloat storage costs, create version-control headaches and, more critically for government agencies, can result in the wrong image appearing on public-facing platforms or in official publications.

What the Local Institutions Are Actually Dealing With

The Australian National University's digital communications team, based on the Acton campus, has been working through a backlog in its image library since late May. The library covers everything from research event photography to promotional assets used across the university's website. Staff there have been cross-referencing files flagged by deduplication software against original upload records to determine which version carries the correct rights clearance and metadata before anything is deleted.

The University of Canberra, whose campus sits at Bruce in Belconnen, is facing a comparable challenge inside its marketing division. UC's content team began a structured review of its Canva-integrated and SharePoint-hosted image repositories in June, according to a publicly posted project update on the university's intranet — a process the team estimated would take around six weeks to complete. That puts them midway through the work as of this week.

Neither institution is alone. Across London Circuit in the ACT government precinct, agencies managing public-facing digital services have been receiving guidance from the ACT Digital, Data and Technology division about aligning local asset management practices with the broader Commonwealth framework, even where the federal rules do not directly bind territory bodies.

The Numbers Behind the Problem

Scale is part of why this has become urgent. A 2025 benchmark report from the global Digital Asset Management community — cited in trade publication DAM News — found that organisations with more than 10 years of accumulated digital files typically carry a duplication rate of between 30 and 45 percent across their image libraries. For a mid-sized government agency storing tens of thousands of assets, that translates directly into measurable storage spend. AWS S3 storage costs in the Asia-Pacific region currently run at roughly AU$0.025 per gigabyte per month, meaning a library with even 500 gigabytes of redundant image data is generating around $150 a month in unnecessary expenditure — modest for a single agency, but material across a portfolio of dozens.

The remediation tools now being deployed vary. Some agencies are using Adobe Experience Manager's built-in similarity detection. Others are running open-source tools like DupeGuru across network drives before migrating curated libraries to cloud platforms. The Digital Transformation Agency's guidance does not mandate a specific tool, leaving agencies to select what fits their existing infrastructure.

For Canberra's public service workforce — which commutes in from growth suburbs like Gungahlin and Tuggeranong — the practical day-to-day impact is mostly invisible. But for the communications officers and web managers in offices along Northbourne Avenue and around the Civic precinct, the first week of July has meant working through queues of flagged files, making judgement calls on what to keep and documenting those decisions for future audits.

The next checkpoint is September 30, when agencies are expected to submit updated Digital Asset Maturity assessments to the Digital Transformation Agency. That report will include a section specifically on media asset hygiene. Agencies that have not made demonstrable progress by then risk being flagged in the broader whole-of-government digital reporting cycle. For communications teams, the practical advice is straightforward: start with the oldest archive folders, prioritise anything that has been used on public-facing pages in the past 24 months, and build a naming convention now that prevents the same problem recurring.
