Canberra's Duplicate Image Problem: The Key Decisions That Will Shape What Comes Next

Canberra's public sector has a digital housekeeping problem that is quietly consuming storage budgets and creating compliance headaches across dozens of agencies. Duplicate images — redundant copies of the same photograph, scan or graphic file stored across multiple systems — have accumulated across ACT government directorates and Commonwealth bodies headquartered in the capital, and the pressure to clean them up is now coming from multiple directions at once.

The issue has sharpened in mid-2026 for a specific reason: the ACT Government's Digital Strategy review, which has been running since early this year, is expected to produce binding data-management guidelines before the end of the third quarter. Those guidelines are likely to set retention and deduplication standards that will affect everything from the National Archives of Australia's digitisation programs in Mitchell to the Australian National University's research image repositories in Acton.

Why This Matters Beyond the Server Room

Duplicate images are not a trivial inconvenience. They inflate cloud storage costs, complicate Freedom of Information responses, and — particularly in the health and legal sectors — carry real risk if an outdated image file is retrieved instead of the correct current version. For Canberra, where the public service workforce is the dominant employer along the Northbourne Avenue corridor and out into Gungahlin, the operational stakes are high. A single agency managing tens of thousands of case files can hold multiple redundant copies of the same scanned document, each stored in a different folder structure by a different team.

The University of Canberra's Health Research Institute at Bruce has flagged the issue in the context of medical imaging records, where a duplicate scan attached to the wrong patient episode represents a patient safety concern, not merely a storage inefficiency. The Institute has been piloting deduplication software since March 2026 as part of a broader data governance project, though no outcomes from that pilot have yet been made public.

At the federal level, the National Archives facility in Mitchell holds physical and digital collections where duplicate digitisation — the same document scanned twice by different projects — has been identified as a recurring problem. The Archives' annual report for 2024–25 noted that its digital preservation holdings had grown to more than 200 terabytes, a figure that includes material that has not yet been fully audited for duplication.

The Decision Points Ahead

Three decisions will define how this plays out over the next six to twelve months. First, the ACT Digital Strategy review must decide whether deduplication will be mandated or merely recommended for directorates — a distinction that will determine whether agencies actually act or simply note the guidance and move on. Second, procurement officers across agencies need to choose between enterprise-level deduplication tools, which typically carry licensing costs upward of $80,000 per year for a mid-sized agency, and open-source alternatives that require more internal technical capacity to maintain.

Third, and most consequentially, agencies must decide who owns the problem. Without a clearly assigned data custodian, deduplication projects tend to stall at the audit stage. The ACT Government's Chief Digital Officer directorate, based in London Circuit in the city, has indicated it wants agencies to nominate a data steward for image assets by September 2026, but it has not yet specified what authority those stewards will have to compel action across teams.

For public servants in Barton, Phillip and the outer growth suburbs who interact with government digital systems daily, the practical upshot is straightforward: the agencies most likely to get ahead of this are those that begin internal audits now, before the guidelines land and create a compliance scramble. The agencies that wait will face the same work in a shorter timeframe, probably with less budget flexibility. The coming months will reveal which category most Canberra directorates fall into.
