Duplicate Images in Government Records: What Officials, Experts and Key Figures Are Saying

The problem has a deceptively mundane name. Duplicate image replacement — the process of identifying and removing redundant digital files from government databases — has moved quietly from the IT helpdesk to the boardroom across Canberra's public sector, as agencies grapple with bloated records systems that affect everything from planning approvals in Gungahlin to welfare case files managed out of Tuggeranong.

The issue has sharpened in 2026 because several large federal agencies are mid-cycle in digital modernisation programs that began under the previous government's Data and Digital Strategy, a framework that set a 2025 deadline for agencies to audit their records holdings. That deadline has now passed, and the audit results — where they exist — are telling an uncomfortable story about how much duplicated visual data governments are sitting on.

Why Canberra's Public Sector Feels This Differently

Canberra is not a typical city when it comes to digital records. The concentration of Commonwealth departments along the Parliamentary Triangle, combined with the ACT Government's own expanding digital service layer, means the capital holds a disproportionate share of Australia's public-sector image data. Think satellite imagery used by the National Capital Authority for planning decisions, scanned identity documents held by Services Australia at its Greenway facility, and heritage photography archives maintained by the National Library of Australia on Parkes Place.

Services Australia alone processes millions of document scans annually. When the same scanned form is uploaded twice — a common error during high-volume periods — it creates storage costs, slows retrieval times, and, in some compliance contexts, can trigger duplicate assessment workflows that affect real people's payments or approvals. The Australian National University's 3A Institute, which has published research on responsible data systems, has flagged that image deduplication is one of the less glamorous but more consequential gaps in public-sector data hygiene frameworks.

The ACT Government's own Digital Strategy, updated in late 2024, identified data quality as a priority investment area for Territory agencies through to 2027. The strategy did not put a dollar figure on the duplicate records problem specifically, but it noted that storage costs for Territory agencies had risen materially over the preceding three years — a period that coincided with the rapid digitisation of services across Health, Education, and Access Canberra.

The Pressure to Act — and the Disagreement About How

There is no single agreed fix. Some records managers argue for automated deduplication tools that scan for identical hash signatures — essentially digital fingerprints — in image file libraries. Others, particularly those working in heritage and legal contexts, warn that not all duplicate images are truly redundant: a second scan of the same document may exist because the first was degraded or incomplete, and deleting it without human review risks destroying the better copy.

The National Archives of Australia, headquartered in Mitchell, has been working through its own backlog under the Archives Legislation Amendment Act 2022, which expanded the definition of Commonwealth records to include more digital file types. That expansion created a new compliance obligation for agencies to demonstrate records integrity — and duplicate images sit awkwardly in that framework, since an unreviewed duplicate could be either a redundant copy or, in some cases, a legally significant second original.

University of Canberra researchers in the Faculty of Arts and Design, which runs one of the country's few dedicated programs in archives and records management, have pointed to the need for clearer national guidance rather than agency-by-agency policy improvisation. Without a consistent standard, different departments within the same precinct on London Circuit can be applying entirely different thresholds for what counts as a duplicate worth deleting.

For public servants working in the suburb of Barton or filing documents through the myGov platform from their homes in Belconnen, the practical upshot is a system that can feel slower and less reliable than it should be. The pressure from agency CIOs is real and growing. Expect the conversation to move from background noise to formal policy discussion before the end of the 2026 financial year — particularly if the current federal budget review identifies storage expenditure as a savings target, which several budget submissions from line agencies have already flagged as a possibility.
