Canberra Agencies Move to Fix Duplicate Image Problem Clogging Government Digital Archives

ACT government agencies spent much of this week grappling with a long-deferred problem: tens of thousands of duplicate images sitting inside shared digital asset systems, slowing workflows, inflating storage costs and making records management a mounting compliance risk. The Territory Records Office confirmed it has been coordinating with multiple directorates since late June to scope the scale of the issue ahead of a broader digital asset audit scheduled for August.

The timing matters. The ACT government is mid-cycle on its Digital Canberra 2025–2028 strategy, which commits agencies to reducing redundant data holdings and improving interoperability across platforms. Duplicate image files — photographs, scanned documents, graphics recycled across departments without version control — have emerged as one of the more stubborn technical obstacles to hitting those benchmarks. Budget pressures are also sharpening minds: cloud storage costs for the ACT public service have risen alongside broader infrastructure spending, and every unnecessary gigabyte has a dollar value attached to it.

What Happened This Week

The Australian National University's College of Engineering, Computing and Cybernetics hosted a working session on Wednesday with representatives from the ACT Chief Minister, Treasury and Economic Development Directorate and the City Services Directorate. The session focused on deduplication tooling — automated software capable of scanning image libraries, identifying pixel-level or metadata-based duplicates, and flagging them for human review before deletion. No procurement decision was announced, but attendees left with a shortlist of three commercial platforms being tested in sandbox environments.

Separately, the ACT Libraries network, which maintains public-facing digital collections across its Civic, Belconnen and Gungahlin branches, confirmed it is piloting a deduplication workflow for its photographic archive this month. The archive holds historical images of Canberra dating to the early twentieth century, many of which were digitised in multiple batches over the past two decades and exist in duplicate or triplicate at varying resolutions. The Belconnen branch has been nominated as the test site, with results expected by the end of July before any system-wide rollout.

The University of Canberra's Centre for Creative and Cultural Research has also entered the conversation, offering methodological advice on how institutions should handle cases where apparent duplicates are actually distinct records — for instance, images that were intentionally altered for different publication contexts. That distinction matters legally under the Territory Records Act 2002, which governs what ACT public bodies can delete from official holdings.

Why It Costs Real Money

Storage is not free. Industry benchmarks from the Australian Government's Digital Transformation Agency suggest that poorly managed cloud environments routinely carry 20 to 40 percent redundant data. For an agency running image libraries in the hundreds of gigabytes — not unusual for a directorate managing planning approvals, infrastructure photography or public communications — that translates to ongoing annual expenditure that deduplication could substantially reduce.

The ACT's 2025–26 budget allocated funds to ICT infrastructure reform across several directorates, though the government has not publicly broken out a specific line item for digital asset management. Practitioners at Wednesday's ANU session pointed to local government case studies from New South Wales and Victoria where deduplication projects returned storage savings within six to twelve months of implementation.

Staff in the Russell offices of several Commonwealth agencies — technically outside ACT jurisdiction but sharing physical infrastructure and, in some cases, contracted digital services with Territory bodies — have been watching the process closely, according to public tender documents lodged with AusTender in June that reference cross-jurisdictional data hygiene requirements.

The practical next step for ACT public servants dealing with this week-to-week is straightforward: the Territory Records Office is expected to publish interim guidance before the end of July on how agencies should document duplicate findings during the audit period, including a decision tree for distinguishing deletable copies from records that must be retained. Agencies on Northbourne Avenue and in the Civic precinct have been asked to nominate a digital records contact by July 18. The August audit will set the baseline against which any future deduplication investment is measured.
