How Canberra's Public Sector Got Buried in Duplicate Images — and Why the Bill Is Finally Coming Due

The problem did not appear overnight. Across Canberra's dense cluster of federal agencies — from the Department of Finance on Kings Avenue to Services Australia's Tuggeranong offices — thousands of terabytes of storage are occupied by duplicate image files: scanned documents photographed twice, stock photos saved once per inbox, and archived records replicated across shared drives every time a new project team spun up. The ACT government's Digital Strategy Review, which concluded its first phase in late 2025, flagged duplicate asset management as one of three core inefficiencies draining agency IT budgets before a single line of new code is written.

The timing matters because Canberra's public service is under simultaneous pressure from two directions. The Albanese government's ongoing efficiency dividend — which trimmed agency operating budgets by a cumulative amount across the forward estimates — pushed IT departments to scrutinise storage costs they had previously treated as a fixed overhead. At the same time, the ACT government's ongoing rollout of a shared digital infrastructure platform for territory agencies brought image duplication into sharp relief: when you try to merge repositories, you find out fast how many copies of the same file you own.

How the Duplication Built Up

The roots go back further than most IT managers care to admit. When the Australian Public Service began its shift from paper to digital records in the early 2000s, individual agencies procured their own content management systems. Geoscience Australia in Symonston ran different software from the Australian Bureau of Statistics in Belconnen. The Department of Infrastructure, headquartered in Alinga Street in the city centre, used platforms incompatible with those in the Attorney-General's Department a kilometre away on Marcus Clarke Street. Each system saved its own image cache. None of them talked to each other.

The National Archives of Australia, based at its Mitchell repository, has long documented the consequences. Its successive annual reports have noted the challenge of ingesting digitised records from agencies that had independently scanned the same physical documents during different retention review cycles — meaning the Archives itself has received duplicate image sets from agencies that separately digitised shared Cabinet papers or cross-departmental correspondence. The problem is structural, not the result of individual carelessness.

Growth suburbs added another layer. As federal agencies decentralised back-office functions to Gungahlin and Tuggeranong through the 2010s, satellite offices created their own local file shares rather than connecting cleanly to centralised servers. Image assets — training materials, communications graphics, scanned HR files — proliferated across those nodes. By the time cloud migration became policy, the duplication had compounded.

What the Fix Actually Looks Like

The ACT government's Shared Services team, operating out of its Greenway facility in Tuggeranong, has been piloting a duplicate-detection workflow since March 2026 as part of its broader Digital Asset Management Program. The approach uses hash-based fingerprinting to identify identical or near-identical image files before consolidating storage pools. Agencies participating in the pilot — which include several ACT Health directorates and Transport Canberra — have reported finding multiple copies of the same scanned policy document saved under different filenames across different folders, sometimes dozens of times over.

The Australian National University's 3A Institute, which works on responsible technology governance, has been engaged in broader conversations about data lifecycle policy across the ACT public sector, though no formal contract with the ACT government has been publicly announced. The University of Canberra's Centre for Creative and Cultural Research has separately examined digital asset preservation questions in an Australian government context, pointing to a gap between retention obligations and practical storage discipline.

For federal agencies, the Digital Transformation Agency's whole-of-government cloud policy — last updated in its published guidance in 2024 — sets expectations around data deduplication in cloud environments, but compliance remains agency-by-agency. Storage costs for government cloud contracts are not publicly itemised, meaning the full financial scale of the duplication problem across Commonwealth agencies is not publicly known.

For Canberra's legions of public servants, the practical upshot is coming. Agencies participating in shared-platform rollouts will increasingly be asked to audit image libraries before migration deadlines. IT teams in Barton and Woden should expect deduplication audits to become a standard part of procurement and platform renewal cycles over the next 12 to 18 months — a mundane but overdue piece of housekeeping that the sector has deferred long enough.
