Canberra's Duplicate Image Problem: How the Capital Stacks Up Against Cities Tackling Digital Record Clutter

Federal agencies based in Canberra collectively store billions of digital images across departmental servers, cloud platforms and legacy systems — and a growing share of that storage is consumed by exact or near-exact duplicates. The problem is not unique to the capital, but the concentration of Commonwealth departments between Civic and Barton makes the ACT ground zero for Australia's attempt to bring order to sprawling government image libraries.

Duplicate image proliferation has become a live issue for records managers in 2026, driven partly by the rapid expansion of cloud migration projects that began accelerating after the Australian Public Service Commission's digital uplift initiatives from 2022 onward. When agencies move legacy data in bulk, duplicates travel with it — sometimes multiplied further by the migration process itself. The result is storage costs that compound annually and retrieval systems that slow under the weight of redundant files.

The Australian National University's 3A Institute in Acton has been examining the governance dimensions of automated data management, including how machine-learning deduplication tools interact with public records obligations under the Archives Act 1983. Separately, the National Archives of Australia, headquartered on Queen Victoria Terrace in Parkes, has been updating its digital preservation frameworks to address exactly this kind of redundancy — though the pace of that work has drawn scrutiny from records professionals who argue government digitisation is outrunning the archival rulebook.

What Other Cities Are Doing

Amsterdam and Singapore — both comparable to Canberra in the sense that their economies are anchored by administrative and knowledge-sector employment — have moved further toward centralised deduplication infrastructure. Amsterdam's municipal digital office adopted a city-wide image hashing protocol across council departments in 2024, allowing automated flagging of duplicates before they enter permanent storage. Singapore's Government Technology Agency, GovTech, has mandated perceptual hashing standards for all static image assets ingested by ministries since January 2025.

Wellington, arguably the closest international parallel to Canberra given its capital-city public service character, began a whole-of-government digital asset audit in late 2023. New Zealand's Department of Internal Affairs reported that pilot agencies found between 18 and 31 per cent of stored images were duplicates or near-duplicates, according to documentation published by that department. Canberra's agencies have not published equivalent figures publicly, making direct comparison difficult — but storage procurement patterns within the Digital Transformation Agency suggest the problem is at least as acute here.

The contrast matters because Australia is currently spending significantly on cloud storage expansion. The federal budget committed substantial resources to APS digital infrastructure in 2025-26, and records professionals argue that deduplication should be built into procurement contracts rather than treated as a cleanup task after the fact. Every terabyte of duplicate images sitting on a Commonwealth server in Canberra's Mitchell data centre precinct represents recurring cost with zero information value.

Local Stakes and What Comes Next

For Canberra's public servants — many of whom live in Gungahlin and Belconnen where housing costs have pushed younger APS employees further from the city — the issue is less abstract than it sounds. Agencies that waste storage budgets on redundancy have less to spend on the tools and systems that make daily work faster. The Digital Transformation Agency, based on Constitution Avenue in Reid, is the body best positioned to set whole-of-government standards, but it has not yet mandated a common deduplication approach across agencies.

Records managers and ICT procurement officers advising agencies currently recommend three practical steps: audit existing image repositories using open-source hashing tools before any new cloud migration contract is signed; embed deduplication clauses in vendor agreements; and align image retention policies with the National Archives' Digital Continuity 2025 policy framework, which sets baseline expectations for how agencies manage digital assets over time.

The global comparison is instructive precisely because cities like Singapore and Wellington moved early, set standards centrally and avoided the cleanup costs that accumulate when agencies are left to solve the problem in isolation. Canberra has the institutional machinery to do the same. The question is whether the relevant agencies will act before the next round of bulk digitisation locks in another generation of redundant files.
