Duplicate Image Replacement in Canberra's Public Records: What Happens Next and the Key Decisions Ahead

A quiet but consequential reckoning is underway inside Canberra's bureaucratic corridors. Government agencies across the ACT and federal public service are confronting a backlog of duplicate digital images embedded in public records, planning documents and online asset libraries — and decisions made in the next several months will shape how those records are managed for years to come.

The issue cuts across virtually every department that digitised paper archives during the pandemic-era work-from-home scramble between 2020 and 2022. Rushed scanning programs, inconsistent file-naming conventions and the use of multiple cloud storage platforms left many agencies holding redundant copies of the same images across different systems, with no standardised process for identifying or retiring them.

Why It Matters Right Now

The stakes are higher than they might appear on the surface. Duplicate images in planning and land management records — particularly those held by the ACT Planning directorate covering growth corridors like Gungahlin and Molonglo Valley — create real risk when contradictory versions of site photographs or cadastral maps are attached to development applications. A building approval referencing an outdated or mismatched image of a Flemington Road streetscape, for example, could trigger delays or disputes during the ACT Civil and Administrative Tribunal review process.

At the federal level, the National Archives of Australia, headquartered on Queen Victoria Terrace in Parkes, has been working through its digital preservation framework since at least 2023. The Archives' own guidelines require that agencies submit a single authoritative digital object for each record rather than multiple renditions, but compliance across the broader Australian Public Service remains patchy. The Australian National University's digital humanities teams, based at the Chifley Library precinct on Acton Peninsula, have separately flagged the problem in the context of research repositories — where duplicate images inflate storage costs and confuse citation trails.

Storage is not cheap. Cloud data management contracts across federal agencies run into the tens of millions of dollars annually, and duplicate image files — which can represent anywhere from 8 to 15 percent of total stored data in poorly governed systems, according to data management benchmarks published by industry bodies — represent dead weight that agencies are now under pressure to eliminate as part of budget efficiency reviews flowing from the 2025-26 Commonwealth Budget.

The Decisions That Can't Wait

Three choices are sitting on agency desks right now. First, whether to conduct a full audit using automated deduplication software or rely on manual review — a distinction that matters enormously for smaller ACT government bodies like Access Canberra, which handles everything from vehicle registration imagery to streetworks documentation out of its Dickson Service Centre operations.

Second, agencies must decide who owns the authoritative version of a duplicated image when two different directorates hold conflicting copies. The ACT's Digital Strategy, updated in late 2024, nominates the originating business unit as the record owner, but enforcement of that principle across shared platforms like Microsoft SharePoint environments used by Territory and Municipal Services remains inconsistent.

Third — and most practically — agencies need to settle on a retention and destruction timeline. Under the Territory Records Act 2002, deletion of a government record requires formal authorisation. That means even obvious duplicates cannot simply be deleted without paperwork, a fact that slows remediation considerably and adds administrative load to already stretched information management teams.

For Canberrans working in the public service — the city's single largest employment sector — the practical upshot is straightforward: expect internal guidance from agency information management branches over the next quarter, likely before the end of September 2026. Staff who regularly upload images to shared drives or document management systems should watch for updated file-naming protocols and mandatory metadata fields. Agencies piloting automated deduplication tools are likely to flag results through internal audit committees first before any system-wide changes take effect. The window for getting this right, before the next major digitisation push tied to Light Rail Stage 2 planning documentation, is narrow.
