Canberra's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

ACT government agencies are facing a hard reckoning over their digital records holdings, with a Territory-wide audit completed in June 2026 identifying tens of thousands of duplicate images stored across multiple departmental systems — driving up storage costs, creating compliance headaches, and threatening the integrity of public records under the Territory Records Act 2002. The audit, conducted across agencies including Access Canberra and the ACT Health Directorate, found that duplicated digital image files account for a measurable share of total storage expenditure across whole-of-government platforms.

The timing matters. The ACT government's whole-of-government digital records strategy, which sets a rationalisation milestone for mid-2027, is now the forcing mechanism pushing agencies to decide whether to invest in automated deduplication software, consolidate onto a single content management platform, or continue managing records manually — a path most IT administrators consider untenable given current volumes.

What the Audit Found — and Where the Problem Is Deepest

The duplication issue is not evenly distributed. Agencies that underwent rapid digital transformation during 2020 and 2021 — scanning backlogs of physical files, absorbing legacy systems from restructured directorates — accumulated the heaviest concentrations of redundant image files. The Canberra Health Services network, which operates from Garran and the Calverton Park precinct in Belconnen, is understood to hold patient-adjacent administrative image records across at least three separate repository systems that were never fully merged after the 2019 health directorate restructure.

At the Australian National University on Acton Peninsula, a separate but parallel problem has emerged inside the Chifley Library's digital collections team, where scanning programs running since 2018 produced overlapping image sets across different grant-funded projects. ANU's University Library confirmed in a June 2026 update to its digital preservation roadmap that a deduplication review is underway, though no completion date has been publicly set. The University of Canberra, operating from its Bruce campus, faces similar pressures inside its institutional repository, which feeds into the national TROVE aggregation system maintained by the National Library of Australia on Parkes Place.

Storage costs are real. Commercial cloud storage for large image files — typically TIFF masters running between 50 megabytes and 200 megabytes each — can run to several thousand dollars per terabyte annually under enterprise licensing arrangements. Agencies holding tens of thousands of duplicate masters are, in effect, paying twice for the same data. The Territory's whole-of-government Microsoft Azure contract, renewed in late 2025, includes tiered pricing structures that make eliminating redundant files a straightforward cost-saving measure on paper, but the human work of verifying which copy is the authoritative record before deletion is neither quick nor cheap.

The Decisions That Will Define the Next 12 Months

Three choices sit in front of agency chief information officers right now. The first is automated deduplication — software tools that hash image files, identify exact or near-exact matches, and flag them for review. Vendors including Iron Mountain and Microsoft have pitched solutions to the ACT government. The risk is that automated systems can misidentify distinct records as duplicates if metadata is inconsistent, a problem that archivists at the National Archives of Australia, headquartered on Queen Victoria Terrace in Parkes, have documented in guidance published in early 2026.

The second option is platform consolidation — migrating all image holdings onto a single content management system and using that migration as the deduplication event. This is the more expensive path upfront, with whole-of-government content platform projects in comparable jurisdictions running into the tens of millions of dollars over multi-year rollouts.

The third option is doing nothing structured and managing duplication case by case. Most digital records specialists consider this the most expensive choice in the long run, both financially and in terms of future compliance risk under the Territory Records Act.

Agencies have until the end of March 2027 to submit their individual remediation plans to the ACT's Chief Digital Officer. For public servants in Civic and across the Gungahlin and Tuggeranong service centres who rely on accurate document systems daily, which path agencies choose will determine whether the backlog gets cleared — or simply grows larger while the debate continues.
