Digital Clutter Crisis: What Canberra Officials and Experts Are Saying About Duplicate Image Replacement

Canberra's public sector is staring at a growing digital housekeeping problem. Across government agencies, research universities and local councils, duplicate images — photographs, scanned documents, satellite stills and design assets copied and re-copied across shared drives — are consuming server space, slowing workflows and, in some cases, undermining the integrity of official records. Technology managers and archival specialists in the capital are now pushing for systematic duplicate image replacement programs rather than the ad hoc deletions that have characterised past practice.

The timing is not accidental. The ACT Government's Digital Strategy, which set a 2025 target for agencies to migrate legacy records to cloud infrastructure, has forced a reckoning with exactly what is sitting in those legacy stores. In many cases, the answer is: a lot of redundant visual data accumulated over years of departmental mergers, machinery-of-government changes and the expansion of digital photography across the public service.

What the Institutions Are Saying

At the Australian National University on Acton Peninsula, library and research data teams have been grappling with the problem in the context of academic image repositories. The university's Scholarly Communication and Research Services unit has been working with faculties to audit visual assets as part of broader research data management requirements under the Australian Code for the Responsible Conduct of Research. Duplicate or near-duplicate images in research datasets can skew outputs and create compliance headaches when work is submitted for publication or grant acquittal.

The University of Canberra's library precinct on Kirinari Street in Bruce has similarly been advising student researchers and staff on image deduplication as part of its research integrity workshops — sessions that have grown in attendance since the Australian Research Council tightened its data management policy requirements in late 2024.

Inside the ACT public service, the picture is more fragmented. The Chief Digital Officer's office has acknowledged the issue broadly under its records management framework, but agencies retain significant autonomy over how they manage internal digital assets. The result is inconsistency: some directorates have invested in software tools capable of hash-based duplicate detection, while others are still relying on manual folder audits conducted by administrative staff.

Industry specialists who advise federal and territory government clients in Canberra's Barton and Fyshwick technology precincts say the core challenge is not technical — detection algorithms are mature and relatively cheap to deploy. The harder problem is governance: deciding which version of a duplicated image is the authoritative one, who has the power to delete the others, and how to document that decision for audit purposes under the Archives Act 1983.

Why Replacement Matters More Than Deletion

Simply deleting duplicate images is not always the right answer, particularly in agencies where images serve as evidentiary records. Archivists and records managers draw a sharp distinction between deletion and replacement — the latter involves substituting a lower-quality or incorrectly versioned image with the correct, authoritative asset while preserving a documented chain of custody. That distinction matters enormously for Freedom of Information compliance and for any agency subject to parliamentary scrutiny.

The National Archives of Australia, headquartered in the Parkes precinct on Queen Victoria Terrace, sets the framework that Commonwealth agencies must follow. Its Digital Continuity 2025 policy requires agencies to ensure that digital records are authentic, complete and usable — criteria that a sprawling landscape of unchecked duplicates can compromise.

From a cost perspective, cloud storage is not free. Microsoft Azure and Amazon Web Services pricing structures — both used extensively across ACT government and Commonwealth tenancies — charge by volume. An agency storing three copies of every image it has ever received pays roughly three times what it should, a figure that compounds quickly across a large portfolio.

For Canberra institutions looking to act now, the practical path forward involves three steps: commissioning a baseline audit using automated deduplication tools, establishing a governance policy that names authoritative sources for each image category, and running a structured replacement process — not a deletion sweep — that satisfies records management obligations. The ACT Government's Digital Services division and the National Archives both publish guidance frameworks that can anchor that process. The work is unglamorous. It is also overdue.
