Canberra's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

The ACT government is sitting on a sprawling, largely unaudited backlog of duplicate digital images embedded across multiple public-facing and internal records systems, and the decisions made over the next six months will determine whether agencies face a costly manual remediation process or a managed technology-led fix.

The problem is not unique to Canberra, but it lands here with particular weight. The Territory's public service is disproportionately large relative to population — the ACT accounts for a significant share of Commonwealth and Territory-level administrative records — and the duplication issue has compounded over years of system migrations, departmental restructures, and rushed digitisation programs that accelerated during COVID-19 restrictions between 2020 and 2022.

Why the Decision Can't Wait Much Longer

Digital asset management has moved to the top of the agenda for several ACT directorates following a broader push from the Commonwealth toward standardised records governance. The National Archives of Australia, based on Queen Victoria Terrace in Parkes, updated its digital preservation guidance in late 2025, placing new obligations on Territory agencies that receive Commonwealth funding to maintain clean, non-duplicated image records in formats compliant with the updated Australian Government Recordkeeping Metadata Standard.

At the local level, the ACT's own Digital Strategy 2025–2028, administered through the Chief Minister, Treasury and Economic Development Directorate on London Circuit, identifies data quality as a Tier 1 priority. Duplicate images — particularly in planning, property, and health records — create real downstream problems. Planning applications lodged through the ACT Planning portal have in some cases contained conflicting image versions of the same site, creating delays in development assessment that add weeks to timelines already stretched by high demand in growth suburbs like Gungahlin and Belconnen.

The University of Canberra's Health Research Institute, located on Kirinari Street in Bruce, flagged in a 2025 internal review that its digital pathology image library contained a duplication rate estimated at between 12 and 18 percent, consuming unnecessary server storage and creating version-control risks for researchers. The institute is now one of several ACT organisations piloting automated deduplication software ahead of a broader procurement decision expected in the third quarter of 2026.

The Fork in the Road for ACT Agencies

There are two broad paths forward, and both carry costs. Manual remediation — staff reviewing and culling duplicate images record by record — is considered reliable but expensive. Rough industry benchmarks suggest manual deduplication of a mid-size government image archive can run to several hundred thousand dollars in labour costs alone, depending on the size of the dataset and the complexity of metadata tagging required.

Automated deduplication tools, several of which are already on the Digital Transformation Agency's approved vendor panel, offer faster throughput but require upfront configuration and carry the risk of false positives — incorrectly flagging as duplicates images that are substantively different despite visual similarity. For agencies like the ACT Health Directorate, where image integrity is a clinical governance issue, the margin for error is essentially zero.

The Territory government has not yet publicly committed to a single procurement approach. A decision framework is understood to be under development within the Digital, Data and Technology Solutions division, though no public consultation has been opened as of early July 2026.

For public servants across the city — the bulk of Canberra's working population, concentrated in offices along Northbourne Avenue and Constitution Avenue — the practical upshot is a period of uncertainty. Staff in records and information management roles, particularly those at agencies that are mid-migration to cloud-based document platforms, may face additional workload as interim manual checks are required while the procurement question remains open.

The next firm deadline is September 30, 2026, when ACT agencies must submit updated digital asset registers under the Territory Records Act 2002. That date will function as a pressure valve. Agencies that cannot demonstrate a plan for resolving duplicate image backlogs by then are likely to face escalating scrutiny from the ACT Information Management Office. Getting ahead of it now, rather than scrambling in September, is the only option that avoids a much messier and more expensive remediation down the track.
