Canberra's Digital Archive Problem: The Numbers Behind a Growing Duplicate Image Crisis

Canberra's public sector has a clutter problem you can't see. Across the ACT government's shared digital infrastructure, duplicate images — the same photograph, scan, or graphic stored multiple times across different servers and content systems — are consuming storage capacity at a rate that IT administrators are increasingly flagging as unsustainable. The numbers tell an uncomfortable story.

A pattern playing out in comparable government jurisdictions points to duplication rates of between 20 and 40 percent across unmanaged digital asset libraries. For an organisation the size of the ACT Public Service, which employs roughly 23,000 people and operates dozens of agencies from Civic to Tuggeranong, even a conservative estimate of 20 percent redundancy across shared drives represents a significant and ongoing expenditure on storage infrastructure that delivers zero functional value.

Why This Matters Right Now

The timing is not accidental. The ACT government has been accelerating its digital transformation agenda through the Digital, Data and Technology Solutions directorate, pushing agencies toward consolidated cloud platforms ahead of a broader whole-of-government ICT refresh flagged for completion before the end of 2027. Every agency that migrates to the new environment without first cleaning its data carries its redundancy problem forward — and pays cloud storage rates to do it.

The Australian National University, based on Acton Peninsula, and the University of Canberra at Bruce both operate their own large-scale digital repositories for research outputs, course materials, and institutional records. Universities have historically struggled with duplicate image problems in library systems and learning management platforms, where the same lecture slide deck or journal scan gets uploaded independently by multiple staff members. A 2024 report by EDUCAUSE — a US-based higher education technology association — found that duplicate and near-duplicate files accounted for an average of 28 percent of institutional storage consumption across surveyed universities, a figure that local IT managers say is broadly consistent with what they encounter in the Canberra tertiary sector.

For individual agencies publishing to the web, the stakes are more than financial. The ACT government's main service portal, which underwent a redesign in 2023, pulled content from multiple legacy content management systems during migration. Without automated deduplication tools running during that process, the same image assets — infographics explaining rates notices, photographs of the Lake Burley Griffin foreground used in ministerial press releases — were frequently preserved in multiple locations under different file names. That creates version-control headaches when an image needs to be updated or withdrawn: pull it from one location and it persists in three others.

What Deduplication Actually Costs — and Saves

The tools for solving this are not exotic. Commercial digital asset management platforms with built-in duplicate detection — used by organisations including Services Australia, which operates a large regional processing presence in Canberra's Woden Valley — typically use perceptual hashing algorithms to identify visually identical or near-identical images regardless of file name or format. Licensing costs for enterprise-grade platforms generally range from around $15,000 to $80,000 annually depending on storage volume and user count, figures that local government procurement officers describe as modest against the ongoing cost of unremediated storage sprawl.

Cloud object storage, billed per gigabyte per month, means every redundant file has a recurring price tag. At standard hyperscaler rates in the Australian region — roughly $0.023 per gigabyte per month for common tiers as of mid-2026 — a library carrying 10 terabytes of duplicate image data costs an organisation approximately $2,760 every year for the privilege of storing files it neither needs nor uses. Scale that across a government with dozens of agencies and the figure climbs quickly.

For Canberra organisations looking to act, the logical starting point is an audit before any further cloud migration. The ACT government's own Digital Service Standard, published under the Chief Digital Officer function, recommends that agencies assess data quality as a precondition for system transition — a recommendation that applies squarely to image asset libraries. Practical next steps include running open-source tools such as dupeGuru across internal drives as a low-cost first pass, before commissioning a full digital asset management procurement if the audit confirms the problem is systemic. The data, in most cases, already knows where the waste is.
