Canberra's Digital Archive Problem: What Officials, Experts and Key Figures Are Saying About Duplicate Image Replacement

Federal and territory agencies holding thousands of duplicate images across their digital systems have reached a breaking point, with archivists, IT procurement officers and digital governance specialists now publicly disagreeing about the right approach — and who should pay for it.

The issue has sharpened in 2026 as the Australian Public Service Commission's digital uplift agenda pushes departments to consolidate legacy data holdings before a government-wide cloud migration deadline later this year. Duplicate image files — photographs, scanned documents, logos and graphic assets stored redundantly across multiple servers — represent both a storage cost and a records management liability under the Archives Act 1983.

The debate is no longer a back-office IT conversation. It has surfaced in committee hearings and APS reform circles, with experts warning that without a consistent replacement protocol, agencies risk undermining the integrity of their digital records.

What the Experts Are Saying

Researchers at the Australian National University's School of Computing, located on Acton Peninsula, have been studying automated deduplication tools as part of a broader digital preservation project. The work, which began in 2024, examines how machine-learning classifiers can distinguish between true duplicates and near-duplicate images that carry distinct metadata — a distinction that matters enormously in a public records context.

The University of Canberra's Centre for Creative and Cultural Research, based on Kirinari Street in Bruce, has contributed a parallel perspective, focusing on cultural and heritage collections held by bodies such as the National Library of Australia on Parkes Place. Specialists there argue that automated replacement tools risk stripping provenance data from images that appear identical but were captured at different times or for different administrative purposes.

The ACT Government's Digital Strategy Division, which sits inside the Chief Minister, Treasury and Economic Development Directorate, flagged the issue in its 2025–26 annual priorities document, noting that Territory records systems contained significant redundancy in visual asset holdings. The directorate did not attach a dollar figure to the problem in that document, but independent estimates from procurement consultants working across the public sector place storage costs for redundant digital assets across mid-sized Commonwealth agencies in the tens of thousands of dollars annually per agency.

The National Archives of Australia, headquartered on Queen Victoria Terrace in Parkes, administers the framework under which agencies must manage digital records. Its Digital Continuity 2025 Policy sets baseline requirements for format standards and active management of digital assets, but does not prescribe a specific technical method for handling duplicates — a gap that practitioners say has left agencies improvising.

The Replacement Protocol Debate

The core disagreement is not whether duplicates should be removed, but how the replacement process should be documented and governed. Some IT procurement officers within larger departments favour bulk automated replacement using checksum-matching tools, which can process thousands of files quickly. Digital archivists and records managers, however, are pushing for human review at the point of replacement, arguing that metadata attached to what looks like a duplicate can be legally significant — particularly for images used in policy documents, ministerial briefings or legal proceedings.

The Australian Society of Archivists, which held its national conference in Canberra in May 2026, passed a resolution calling for agencies to develop written duplicate image replacement policies before deploying any automated tool. The resolution does not carry legal force but reflects a professional consensus that the current ad hoc approach carries risk.

For Canberra-based public servants navigating the day-to-day reality, the practical question is timing. Agencies with records systems due for migration before December 2026 face pressure to act quickly. Those with more runway are watching to see whether the Digital Transformation Agency, located on Constitution Avenue in Reid, will issue binding technical guidance — something it has not yet done.

The DTA confirmed in a March 2026 update to its website that guidance on digital asset management was under development but did not commit to a release date. Until that guidance lands, agencies are largely on their own — and the experts are not yet in agreement about what best practice looks like.
