The Numbers Behind Canberra's Duplicate Image Problem: What the Data Actually Shows

Canberra's public sector has a clutter problem measured in terabytes. Audits conducted across several ACT government directorates in the first half of 2026 identified duplicate image files as one of the fastest-growing categories of redundant digital assets, with some departmental shared drives holding multiple identical or near-identical versions of the same photograph, graphic, or scanned document. The scale of the duplication — and the cost of storing it — is finally prompting action.

The timing matters. The ACT Government's whole-of-government digital storage contract comes up for renegotiation later this year, and data management has become a live budget issue in an environment where the territory is already managing fiscal pressure across health, housing, and light rail stage 2 construction on the Northbourne Avenue corridor. Bloated archives push storage costs up and slow the retrieval systems that public servants in Civic and Barton rely on daily.

What the Numbers Look Like on the Ground

Estimates from digital asset management reviews — a category of internal audit increasingly common across Commonwealth and territory agencies — suggest that between 20 and 40 percent of images stored in unmanaged enterprise file systems are duplicates. Apply that range to a mid-sized ACT directorate holding, say, 10 terabytes of image assets, and the redundant portion could represent two to four terabytes of storage that serves no operational purpose. At current enterprise cloud storage pricing in Australia — which has hovered around $25 to $35 per terabyte per month for government-grade services — even a single directorate could be spending several hundred dollars a month on files nobody needs.

The Australian National University's Research Data Storage service, which supports researchers across the Acton campus, has grappled with the same issue. Image-heavy disciplines — archaeology, ecology, medical imaging — generate large volumes of files that researchers often save multiple times across different project folders. ANU's digital infrastructure team has piloted automated deduplication tools as part of broader research data management compliance work tied to the Australian Research Data Commons guidelines. The University of Canberra, whose Bruce campus hosts significant health and communication research, faces comparable challenges in managing image libraries tied to longitudinal studies.

For the ACT Government's own digital records, the relevant policy framework is the Territory Records Act 2002, which governs how agencies must store, manage, and eventually dispose of official records. Duplicate images complicate compliance — if the same scanned document exists in three locations with slightly different metadata, it creates ambiguity about which version is the authoritative record. The Territory Records Office, based in Canberra City, has flagged records duplication as a priority issue in guidance materials updated in 2025.

Deduplication Is Cheaper Than You Think — But Not Free

The practical fix is automated deduplication software, and the market for it has matured. Enterprise tools from vendors including Veritas and Commvault can scan file systems, identify hash-matched duplicates, and flag near-duplicates for human review. Licensing costs for government-scale deployments typically run from $15,000 to $80,000 annually depending on storage volume, according to publicly available vendor pricing tiers — a one-time investment that can recover its cost within a single contract cycle if storage savings are banked.

The harder cost is labour. Running a deduplication project properly requires someone to review flagged files, confirm deletion decisions, and update records management metadata. For a directorate in Phillip or Fyshwick with a small IT team already stretched across desktop support and cybersecurity compliance, that human overhead is the real barrier.

For agencies and institutions approaching this problem in the second half of 2026, the clearest first step is a storage audit — most enterprise storage platforms can generate duplicate reports without specialist software. The ACT Government's Shared Services ICT division, which provides infrastructure support to territory agencies, is the logical starting point for directorates that don't know where their image libraries actually live. Getting that baseline number — how many gigabytes, how many duplicates, how much it costs per month — turns an abstract data hygiene problem into a budget conversation with a concrete answer.
