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

Canberra's federal and territory agencies are sitting on vast collections of duplicated digital imagery — redundant photos clogging storage systems, inflating IT costs, and slowing public-facing platforms — and the question of how well the capital is managing the problem depends heavily on which building on Constitution Avenue you walk into.

Duplicate image replacement, the process of identifying and substituting redundant or near-identical image files stored across digital systems, has quietly become a significant line item in government IT budgets worldwide. The trigger is straightforward: archival digitisation projects accelerated sharply after 2020, and agencies that rushed documents and photographs online created sprawling, unaudited libraries riddled with duplicates. For a city whose economy runs almost entirely on public administration, Canberra has more skin in this game than most.

Where Canberra Sits Relative to Peers

The ACT government's Digital, Data and Technology Solutions directorate has been running a data hygiene program since at least mid-2024, consolidating storage across Health Canberra and the broader ACT Public Service. The National Archives of Australia, headquartered in Parkes on Queen Victoria Terrace, publicly describes its digitisation backlog as a priority — the agency has been processing physical records held at its Mitchell facility north of the city centre, where duplicate scans generated during batch digitisation are an acknowledged operational issue.

Compare that to Wellington, New Zealand, where Archives New Zealand completed a deduplication audit of its digital holdings in 2025 and reduced its active image library by a figure the agency described publicly as substantial, freeing server capacity equivalent to several petabytes. Edinburgh's National Records of Scotland deployed automated hash-matching software across its holdings in 2023, a program that took roughly 14 months to complete. Singapore's National Archives ran a comparable initiative through its ica.gov.sg infrastructure, integrating AI-assisted perceptual hashing to catch near-duplicates that exact-match tools miss.

Canberra's National Archives has not publicly reported comparable completion milestones as of this month. The institution faces a particular challenge: its Canberra holdings span both born-digital records — files that were never physical — and legacy scans produced across several decades of inconsistent digitisation standards, meaning duplicates exist across format types, not just as identical files.

The Cost of Leaving It Unresolved

Storage is not free. Microsoft Azure and Amazon Web Services, which multiple ACT and federal agencies use for cloud infrastructure, charge per gigabyte of data retained. Analysts who cover government IT procurement have noted publicly that deduplication projects in comparable public sector environments typically produce storage cost reductions of between 20 and 40 percent on image-heavy repositories, though outcomes vary depending on the age and origin of the collection.

The Australian National University's 3A Institute, based on the Acton campus, has produced research on data governance frameworks that touches on exactly this kind of infrastructural redundancy. The University of Canberra's Faculty of Arts and Design, situated on Kirinari Street in Bruce, has separately partnered with cultural institutions on archival metadata standards — work that, when applied properly, prevents duplicate image generation at the point of ingestion rather than requiring expensive cleanup later.

The practical gap between Canberra and the leaders — Wellington and Singapore — appears to be less about technical capability than about mandate. Both of those cities completed their deduplication programs under explicit ministerial directives with defined timelines and published outcomes. Canberra's equivalent work is happening, but diffused across individual agencies without a single coordination point or public reporting framework.

For public servants in Tuggeranong, Belconnen and the inner-north who interact with digital asset management systems daily, the operational effect is real: slower search results, conflicting file versions, and storage allocation disputes between business units. For anyone who relies on government image libraries — journalists, researchers, designers working with ACT government procurement — the duplicates surface as inconsistent metadata and broken download links.

The practical next step is fairly clear. Agencies waiting on internal budget approvals should look at the National Archives' Mitchell facility deduplication work as a model for scoping, and the ACT government's Digital, Data and Technology Solutions directorate is the logical coordination point for territory-level consolidation. Whether a cross-agency directive materialises before the next federal budget cycle — which sets IT capital allocations in May 2027 — will determine whether Canberra closes the gap or stays mid-table.
