Canberra's Duplicate Image Problem: What Officials, Experts and Key Figures Are Saying

Digital records managers at ACT government agencies are confronting a problem that has quietly compounded for years: thousands of duplicate images sitting inside public sector document management systems, inflating storage costs, slowing retrieval times and, in some cases, creating compliance headaches under the Territory Records Act 2002. The issue has moved from an IT nuisance to a governance concern, with voices across Canberra's public service and research institutions now calling for a coordinated response.

The timing is not accidental. The federal government's broader push toward consolidated cloud infrastructure — accelerated through the Digital Government Strategy released in 2023 — has forced agencies to audit legacy holdings before migrating data. In that audit process, duplicate imagery is surfacing as one of the most persistent and underestimated categories of digital waste.

Who Is Raising the Alarm

At the Australian National University's College of Engineering, Computing and Cybernetics on Acton Peninsula, researchers working on automated image recognition have flagged the scale of the problem in the public sector context. ANU's research in computational deduplication — the process of identifying and removing redundant copies of image files — has practical applications that agencies in Civic and Barton are increasingly inquiring about, according to publicly available research collaboration listings on the university's website.

The University of Canberra's Institute for Governance, based at the Bruce campus on Kirinari Street, has separately noted in published commentary that poor digital asset hygiene undermines the integrity of public records and creates downstream risks when information is released under Freedom of Information requests. When duplicate images carry different metadata — different timestamps, different authorship fields — they can appear as distinct documents and muddy FOI disclosure processes.

The ACT Government's Digital, Data and Technology Solutions directorate, which oversees shared ICT services across Territory agencies, has acknowledged the issue in public procurement documents. A tender released in late 2024 for records management modernisation listed deduplication capability as a required feature, signalling that the directorate regards the problem as significant enough to include in formal contract specifications.

The Practical Stakes for Canberra Agencies

Storage is not cheap. Enterprise cloud storage for government-grade systems runs at rates that make large volumes of redundant data a genuine budget line item. For context, the ACT Government's whole-of-government ICT spending has consistently sat above $200 million annually in recent budget cycles, with digital storage and infrastructure making up a material share of that figure according to published ACT Budget papers.

The National Archives of Australia, headquartered on Queen Victoria Terrace in Parkes, maintains standards for digital preservation that federal agencies must meet. Those standards, outlined in the Archives' Digital Preservation Policy, require that records be authentic, reliable and usable — a standard that duplicate imagery with conflicting metadata actively undermines. The Archives has previously issued guidance on format normalisation and deduplication as part of its broader digital continuity frameworks.

For frontline agencies dealing with images — think planning applications at the ACT Planning directorate, infrastructure inspection photos from Transport Canberra, or research imagery flowing through health agencies at Woden — the volume of duplicates can be substantial. A single infrastructure inspection project in an area like the Gungahlin town centre corridor can generate hundreds of near-identical photographs taken by different officers on different devices, all filed independently.

Experts working in this space say the solution is not purely technical. It requires policy: clear rules about who files what, when, and in which system. Without those rules, even the most sophisticated automated deduplication tool will struggle to make permanent headway because new duplicates will keep accumulating at the point of creation.

For Canberra agencies reviewing their digital holdings this financial year, the practical advice from governance specialists is to start with a scoped audit of the highest-volume image repositories before committing to any technology platform. The ACT Government's records management framework requires agencies to maintain disposal authorities under the Territory Records Act, which means duplicate images cannot simply be deleted without a documented and approved process. Getting that process right before the next budget cycle closes will determine how much progress agencies can actually demonstrate by mid-2027.
