Canberra's Duplicate Image Problem: How the Capital Compares to Cities Fighting Digital Clutter

Canberra's sprawling network of federal agencies, research institutions and ACT government departments collectively manages tens of millions of digital image files — and a growing share of them are redundant copies burning storage budgets and slowing down content workflows. That reality is pushing local organisations to confront what digital asset managers call the duplicate image problem, and the capital's response looks markedly different from peer cities in Wellington, Edinburgh and Ottawa.

The issue has sharpened in 2026 because several large Commonwealth departments completed migrations to cloud-based content management systems in the first half of this year, a process that routinely surfaces duplicate or near-duplicate image libraries accumulated over decades of decentralised file storage. When agencies move servers, the problem becomes visible and expensive very quickly.

What Canberra Is Actually Doing

The Australian National University's Digital Collections team in Acton has been running a deduplication audit since February, working through a library of research photography and archival scans that staff estimate runs to more than four million individual files. The university adopted perceptual hashing software — tools that match visually similar images even when file names, formats or metadata differ — after an earlier manual audit proved unworkable at scale. Across Civic, the National Archives of Australia on Queen Victoria Terrace has been operating a similar program under its digital preservation framework, prioritising government records created before 2000.

The ACT Government's digital services directorate has flagged duplicate asset management as a component of its broader ICT consolidation work, though the territory's relatively small size means it leans heavily on Commonwealth-led tooling rather than building independent infrastructure. That dependency is a recurring theme in Canberra: the city's public sector workforce, which dominates the local economy, tends to follow federal procurement cycles rather than set its own technology agenda.

Compare that to Wellington, New Zealand, where the Department of Internal Affairs runs a centralised digital asset register shared across multiple Crown entities, a model that has reportedly reduced storage redundancy across participating agencies. Ottawa's Shared Services Canada operates on a similar logic, pooling federal image repositories under a single governance structure. Edinburgh's approach sits closer to Canberra's fragmented model, with Scottish Government bodies and the University of Edinburgh managing largely separate systems, though a joint working group formed in late 2024 is attempting to bridge the gap.

The Cost and the Catch

Storage is not cheap, even as per-gigabyte prices continue to fall. Enterprise cloud storage through major Australian providers currently runs between $0.023 and $0.035 per gigabyte per month for cold storage tiers, meaning a department sitting on two petabytes of unaudited image files — a realistic figure for a mid-sized Commonwealth agency — faces ongoing costs that compound every year duplicates go unresolved. The University of Canberra's Bruce campus library, which manages digital collections for several ACT cultural institutions under a shared services arrangement, estimates that deduplication of its holdings has the potential to reduce its annual cloud storage bill by a meaningful margin, though the institution has not released specific figures publicly.

The deeper catch is labour. Automated perceptual hashing tools can flag potential duplicates, but human review is still required before any file is deleted from a government or archival collection. That review burden falls on digital archivists and records managers — roles that the ACT and federal public service have struggled to fill, with the ACT Public Service Commission noting persistent vacancies in specialist ICT and information management classifications as recently as its 2025 workforce planning report.

For Canberra organisations working through this now, the practical advice from digital asset practitioners is consistent: prioritise audit before procurement, since buying new storage to house duplicates is the most expensive non-solution available. Tools like OpenDedup, Rclone and commercial platforms such as Canto or Bynder all offer deduplication modules, but no tool eliminates the need for a clear retention policy signed off by legal and records teams first. The agencies getting ahead of the problem in 2026 are the ones that started the policy conversation in 2024 — before the migration invoices arrived.
