ACT Government's Digital Archives Hit by Duplicate Image Problem — Here's What Changed This Week

The ACT Government's Territory Records Office confirmed this week it is conducting a sweeping audit of digital image holdings across at least four directorates after an internal review identified thousands of duplicate files clogging shared storage infrastructure. The discovery has immediate cost and compliance implications for agencies that depend on clean archives to meet obligations under the Territory Records Act 2002.

The timing matters. The ACT is in the middle of a broader digital modernisation push tied to the government's DataACT strategy, and any failure to maintain clean, non-redundant datasets undermines the integrity of systems that public servants in Civic, Barton and the newly expanded Gungahlin Service Centre rely on daily. Duplicate images — that is, identical or near-identical digital files stored separately and often indexed under different metadata — waste storage capacity, slow retrieval, and can cause version-control failures in document management systems.

How the Problem Surfaced

The issue came to light after staff at the Shared Services Centre in Callam Offices, Woden, flagged anomalies during a routine migration of legacy records into the government's cloud-based document platform. Rather than a handful of stray duplicates, the review found the problem was systemic. Affected holdings include scanned planning documents, permit images, and photographic records held by the Environment, Planning and Sustainable Development Directorate — a particularly sensitive set of files given the current volume of development approvals flowing through suburbs like Molonglo Valley and Belconnen.

The Australian National University's College of Engineering and Computer Science has, separately, been in discussions with ACT Digital since April 2026 about applying machine-learning deduplication tools to public sector image libraries. Those talks are ongoing, according to public meeting agendas published on the ACT Government website, but no formal contract had been announced as of Friday.

Duplicate image problems are not unique to the ACT. A 2024 report by the Australian Information Commissioner found that poor digital asset management across state and territory governments was contributing to storage costs that exceeded projected budgets in multiple jurisdictions. The ACT's current whole-of-government digital storage contract, managed through the Shared Services ICT division, runs to the end of the 2026–27 financial year.

What Agencies Are Doing Right Now

Three directorates — Transport Canberra and City Services, the Planning Directorate, and Access Canberra — have been asked to suspend non-urgent uploads to the central image repository until the audit is complete. A revised timeline circulated internally sets a target of 25 July 2026 for the first-phase review to conclude.

The Territory Records Office is understood to be working with vendors who supply the government's current enterprise content management system to deploy automated hash-matching tools — software that compares files at a binary level to identify exact duplicates before moving to near-duplicate detection. The process is expected to flag tens of thousands of files for human review.

For public servants based at the Hume records storage facility or processing development applications at the Dame Pattie Menzies House offices in Civic, the practical disruption this week has been modest — slower search responses and some temporary restrictions on file uploads. The bigger concern, administrators acknowledge, is the backlog that will accumulate if the audit runs longer than planned.

Residents dealing with planning queries or permit applications through Access Canberra's online portal should be aware that image attachments on some older applications may be temporarily unavailable while files are being verified and reclassified. Access Canberra's service standard for planning-related requests is ten business days, and the directorate has said it does not expect the audit to push processing times beyond that threshold — though that commitment will be tested as the month progresses.

The audit's outcome will also feed directly into budget discussions for the 2027–28 financial year. Storage rationalisation, if successful, could reduce the government's cloud expenditure noticeably, a consideration that carries real weight given the fiscal pressures facing the ACT after the July 2026 mid-year budget update.
