Canberra's Duplicate Image Problem: The Key Decisions Ahead for Government Records

Thousands of duplicate digital images are sitting across ACT government and federal agency servers, costing storage budgets and complicating Freedom of Information requests, records managers and archivists say — and pressure is building to do something about it before the end of the 2026–27 financial year.

The issue has sharpened in Canberra because the capital's workforce is unusually concentrated in the public sector. When agencies duplicate images — whether scanned documents, aerial photographs, satellite imagery, or staff identification photos — the redundancy compounds across dozens of departments sharing overlapping infrastructure. The National Archives of Australia, headquartered on Queen Victoria Terrace in Parkes, is one of several bodies now examining protocols for identifying and culling duplicates without destroying records that may carry legal or heritage value.

Why the Timing Matters

The urgency is partly fiscal. The ACT Government's 2025–26 Budget flagged digital storage costs as a line item under pressure, with the ACT Digital Strategy — administered through the Chief Minister, Treasury and Economic Development Directorate — identifying data deduplication as a priority area. Cloud migration contracts for several ACT Health and Transport Canberra systems are due for review before December 2026, making the next few months a genuine decision window rather than a theoretical one.

At the federal level, the National Archives released updated disposal authority guidance in early 2026 covering born-digital records, but implementation guidance specific to image files — particularly those held in SharePoint environments used across the Australian Public Service — remains patchy. Agencies including the Department of Finance and Services Australia, both with large Canberra workforces, are understood to be working through internal audits, though no public timeline has been confirmed.

The practical stakes are real for anyone who has lodged an FOI request. When multiple copies of an image exist across a department's systems, agencies are technically obliged to locate all of them during a search. That multiplies processing time and cost — a problem the Office of the Australian Information Commissioner, based in Canberra's CBD on Akuna Street, has previously noted as a driver of FOI delays without attributing the cause to any single agency.

The Decisions Ahead

Three questions are now sitting in front of agency records managers and ICT teams across the capital. First: which images qualify as duplicates under the Archives Act 1983, and which are versions carrying distinct metadata that give them separate archival status? A photograph taken at the same moment but processed differently, or stored with a different timestamp, may not be a true duplicate under a strict legal reading.

Second: who holds decision-making authority? In many ACT government agencies, records management sits with one business unit and ICT infrastructure with another. Gungahlin-based Service Access Points and Belconnen's Access Canberra offices both hold locally generated image files — maps, property records, planning documents — that feed into central repositories. Coordinating deletion decisions across those layers is not straightforward.

Third: what tools are being used? Automated deduplication software can match files by hash value, but government image collections often include near-duplicates — slightly cropped or resampled versions — that hash-based tools miss entirely. Procurement of more sophisticated tooling would require approval under the ACT Government's ICT Investment Framework, adding another layer of process.

For public servants and Canberrans whose records sit inside these systems, the practical advice is straightforward: if you have lodged an FOI request that appears stalled, the OAIC's online complaint portal accepts submissions and the Commissioner's office does monitor response times. For records managers inside agencies, the National Archives' Check-up Digital tool — available through its Parkes website — provides a self-assessment framework that explicitly covers image holdings. The window to get this right, before cloud contracts lock in current storage architectures for another three to five years, is narrow and closing.
