Canberra Government Agencies Race to Fix Duplicate Image Problem Plaguing Digital Archives This Week

ACT government agencies began accelerated audits of their digital image libraries this week after a systemic duplicate-image problem surfaced across multiple departmental databases, forcing manual review of records that public servants rely on daily. The issue, which affects digitised planning documents, heritage photography collections and public infrastructure records, has disrupted workflows at several Civic-based directorates since late June.

The timing matters. The ACT is mid-cycle on its Digital Canberra Action Plan, a whole-of-government initiative designed to consolidate legacy data holdings before a scheduled infrastructure migration later this year. Duplicate images — files that are stored multiple times under different metadata tags — inflate storage costs, slow retrieval speeds and, in some cases, cause compliance headaches when records management legislation requires a single authoritative version of a document.

Where the Problem Showed Up

The Environment, Planning and Sustainable Development Directorate, headquartered on Constitution Avenue in Reid, is understood to have the largest backlog, according to publicly available project tracking boards on the ACT Government's data portal. Its heritage unit holds digitised photographs of inner-north Canberra streetscapes dating to the 1920s, and staff discovered this month that a batch migration conducted in early 2025 had generated duplicate image entries across roughly a third of one collection.

The ACT Historic Places team, which operates from the Griffith offices and maintains the territory's built-heritage inventory, was also caught in the same migration sweep. Its records include survey photographs of properties listed under the ACT Heritage Act 2004, and duplicate entries in that system carry legal weight — a misidentified or doubled image attached to the wrong heritage listing can affect development approval timelines on Northbourne Avenue corridor projects and elsewhere.

The Australian National University's digital library, while not an ACT government body, flagged a related but separate issue last month: image-deduplication software it had licensed to cross-reference collections with the ACT government's public archive produced unexpected false-positive matches, flagging distinct images as duplicates. ANU's Chifley Library team paused that program on June 23 pending a vendor review, according to a notice on the library's internal project page cited by staff familiar with the matter.

What Remediation Looks Like — and What It Costs

Fixing duplicate image problems at scale is neither quick nor cheap. Commercial deduplication tools licensed by Australian government agencies typically run between $18,000 and $65,000 annually for enterprise tiers, based on published pricing from vendors active in the Commonwealth procurement marketplace. Manual review, when software flags are unreliable, can add hundreds of staff hours per collection.

The ACT Government's Shared Services ICT division, which provides infrastructure support across directorates, confirmed in its June quarterly update — published on the ACT Government website on July 1 — that storage remediation projects are among the top three ICT priorities for the 2026-27 financial year. The update did not specify dollar figures attached to image-deduplication work specifically.

For Canberrans who interact with planning records — residents in Gungahlin checking subdivision surveys, or Belconnen community groups accessing environmental baseline photography for light rail corridor submissions — the practical consequence is delayed responses to information access requests. The directorate's standard turnaround under the Territory Records Act is 45 business days, but staff have warned informally that image-heavy requests are taking longer while audits run.

The remediation timetable, as outlined in the Shared Services June update, targets clearance of the highest-priority collections by September 30, ahead of the broader infrastructure migration scheduled for the fourth quarter of 2026. Agencies have been asked to submit collection-by-collection risk assessments by July 18. Members of the public with outstanding information access requests involving digitised images can contact Access Canberra on Alinga Street in the CBD to ask whether their request falls within an affected collection, which may allow them to seek priority processing.
