Duplicate Images Are Costing ACT Government Agencies More Than Storage Space

ACT government agencies and Commonwealth departments based in Canberra are sitting on digital asset libraries bloated with duplicate images, with some repositories holding multiple copies of the same file at rates that IT auditors describe as endemic across the public sector. The problem is not new, but the financial and operational cost of ignoring it has grown sharply as agencies expand their online presence and transition to cloud-based content management systems.

Duplicate image files — identical or near-identical photographs, diagrams and graphics stored under different filenames across shared drives, intranets and public-facing websites — consume server space, slow content workflows and inflate licensing reconciliation costs. For a workforce city like Canberra, where dozens of departments maintain their own digital communications teams within a few kilometres of each other along the Parliamentary Triangle and in Barton and Phillip, the redundancy compounds quickly.

What the Data Actually Shows

Industry benchmarks from digital asset management providers suggest that between 20 and 40 percent of files in an unmanaged corporate image library are duplicates or near-duplicates. Apply that range to a mid-sized Commonwealth agency maintaining, say, 50,000 image assets — a conservative count for any department running active social media, ministerial photography archives and intranet content — and between 10,000 and 20,000 files may be redundant. At typical AWS S3 cloud storage rates applicable in the Sydney region as of mid-2026, storing an unnecessary 500 gigabytes of image data costs roughly $15 to $20 per month in direct storage fees alone, before factoring in data transfer, backup redundancy and staff time spent manually searching through cluttered libraries.

The ACT Government's Digital Strategy, which guides technology investment across directorates including the ACT Health Directorate based in Canberra City and Transport Canberra and City Services operating out of Tuggeranong, sets expectations for agencies to rationalise digital assets as part of broader data governance obligations. Compliance reporting has not always kept pace with those expectations. The Australian National University's digital communications division and the University of Canberra, both significant local content producers, face comparable pressures managing image libraries that span decades of institutional photography.

The real cost multiplier is staff time. A communications officer spending 20 minutes per week searching through a cluttered, duplicate-heavy image library loses more than 17 hours per year to that task alone. Across a team of five, that is nearly 90 hours annually — the equivalent of more than two full working weeks. For public servants on Australian Public Service Band 5 or 6 salaries, which typically sit between $85,000 and $105,000 per year as of the most recent APS Enterprise Agreements, that translates to a labour cost of between $7,000 and $10,000 per team per year in wasted search time, before any remediation work begins.

Fixing the Problem — and What It Takes

Automated duplicate detection tools have been available for years, and several are compatible with the content management platforms common across ACT and Commonwealth agencies. Tools that use perceptual hashing — a technique that identifies visually similar images even when filenames or metadata differ — can scan a 50,000-file library in under an hour and flag candidates for deletion or consolidation. The licensing costs for enterprise-grade platforms typically start around $3,000 to $8,000 per year for a mid-sized team, a figure that payback calculations suggest is recoverable within a single financial year when set against labour savings.

The practical barriers are less technical than organisational. Image libraries in large agencies often span multiple teams, business units and legacy systems, meaning no single person holds authority to delete files flagged as duplicates. Canberra's public service culture of risk aversion around data deletion — understandable given Freedom of Information obligations and record-keeping laws under the Archives Act 1983 — means that audits often stall at the recommendation stage.

Agencies beginning a duplicate image audit in the second half of 2026 should map asset ownership before running any automated tool, assign a named records manager to sign off on deletions, and cross-reference flagged files against any active FOI requests logged with the Office of the Australian Information Commissioner. Starting with a pilot on one directorate's SharePoint library, rather than attempting an agency-wide sweep, tends to produce faster results and clearer cost data to justify the broader program.
