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

Thousands of duplicate images are clogging the digital infrastructure of ACT government agencies, costing storage budgets and undermining the reliability of public-facing websites and internal records systems. The problem is not new, but pressure to act has sharpened in 2026, with the ACT's Digital Strategy review entering its final consultation phase this month.

The timing matters. Federal and territory agencies in Canberra operate some of the country's most document-heavy digital environments. The National Archives of Australia on Queen Victoria Terrace holds petabytes of digitised records. The Australian Bureau of Statistics campus in Belconnen processes enormous image datasets as part of the national Census infrastructure. Both organisations, along with ACT government directorates, are expected to respond to updated digital asset management guidelines before the end of the 2026 calendar year.

Why Duplicate Images Become a Governance Problem

Duplicate images are rarely just a storage annoyance. When two versions of the same document image — say, a planning map or a public health notice — exist in different states of edit across a shared system, decisions get made on the wrong version. In a city where planning approvals, land releases, and public service procurement are built on documented evidence, that kind of error carries real cost.

The ACT Planning Directorate, which manages land-use approvals across growth corridors including Gungahlin and the Molonglo Valley, relies on georeferenced image libraries updated by multiple teams. Multiple versions of site photographs and aerial imagery can exist simultaneously across the Directorate's asset management platform and the separate ESRI mapping environment it shares with Transport Canberra and City Services. Neither system has an automated deduplication process as of July 2026, according to publicly available procurement records from the ACT Government Contracts Register.

The Australian National University's library and research data services team documented a related challenge internally when it migrated to a new digital asset management system in late 2024. The migration flagged more than 40,000 duplicate or near-duplicate image files across research project folders — a figure the university's own published digital preservation report cited as a driver for the updated retention policy now in effect across ANU research schools.

The Decision Points Coming Before December

Three concrete decisions now sit on the table for Canberra's major public sector digital managers.

First, the ACT Digital, Data and Technology Strategy — currently in community feedback until 31 July 2026 — will determine whether automated deduplication tools become a mandated part of any new government content management system procurement. If that language makes it into the final document, agencies will have a compliance obligation rather than a discretionary one.

Second, the National Archives is expected to publish revised guidance on digitisation quality assurance by September, following a Senate estimates hearing in May where the Archives' digital preservation approach attracted scrutiny. That guidance will affect how commonwealth agencies across London Circuit and Constitution Avenue handle image redundancy in their record-keeping obligations under the Archives Act 1983.

Third, individual agencies face a practical budget question: retrofitting deduplication tooling onto existing systems costs money that sits outside current operating budgets. The ACT government's mid-year budget update, expected in December 2026, will reveal whether any additional digital infrastructure funding has been allocated.

For public servants working in agencies along Northbourne Avenue or the parliamentary triangle, the immediate practical step is straightforward: check whether your agency's digital asset policy was last updated before 2023. If it was, it almost certainly predates the current generation of AI-assisted deduplication tools, which means the policy does not account for what those tools can now do — or what they get wrong. The ACT Government ICT Portal lists current endorsed products, and as of this week, no AI deduplication tool appears on the approved products list. That gap alone is a decision waiting to be made.
