Canberra's Image Duplication Problem: How the Capital Stacks Up Against Global Peers

Federal agencies in Canberra are sitting on millions of duplicate digital images spread across departmental servers, shared drives, and legacy content management systems — and the bill for storing redundant files is quietly climbing. The ACT's status as a government-workforce city means the problem is more concentrated here than almost anywhere else in Australia, with the Australian Public Service Commission, the National Archives of Australia, and major research institutions like the Australian National University all wrestling with overlapping digital asset libraries.

The issue has sharpened in mid-2026 for a specific reason: the federal government's ongoing Data and Digital Government Strategy, which pushes agencies to consolidate cloud infrastructure before a December 2026 compliance checkpoint, has forced IT teams to actually audit what they're storing. What many found was not pretty. Duplicate images — scanned policy documents photographed twice, departmental headshots saved in three formats, satellite imagery archived redundantly across multiple geospatial units — account for a meaningful share of bloated storage budgets that agencies have largely left unexamined for years.

What Canberra Is Actually Doing

The National Archives of Australia, based on Queen Victoria Terrace in Parkes, has been piloting automated deduplication tooling across its DigitalSafe platform since early 2025. The Archives declined to put a specific figure on storage savings to date, but the program is one of the more structured responses among Canberra institutions. At the ANU's Chifley Library precinct in Acton, the university's digital scholarship team has been running a separate project using perceptual hashing — a technique that identifies near-identical images even when file names or metadata differ — to clean up its Trove-linked collections. Staff there have described the workload as substantial, though no public completion timeline has been announced.

Smaller ACT government agencies have been slower. Several directorates operating out of Civic and the Canberra CBD's Lovett Tower precinct still rely on SharePoint environments with minimal deduplication controls, according to publicly available ICT procurement records. The ACT's Digital Strategy 2025-2028, released by the Chief Minister's directorate, nominates data quality as a priority area but does not set binding targets specifically for image duplication.

How That Compares Globally

Canberra's mixed record looks middling when measured against comparable government-heavy cities. Singapore's Smart Nation initiative mandated deduplication audits across all public sector digital repositories by January 2025, and the Government Technology Agency published results showing a 34 percent reduction in redundant image files across 17 ministries in the first audit cycle — a figure drawn from GovTech Singapore's published annual report. Amsterdam's municipal digital archive, Stadsarchief Amsterdam, completed a similar exercise in 2024 and publicly reported eliminating roughly 2.1 million duplicate records, including image files, from its online collections.

Wellington, New Zealand — arguably the closest structural comparison to Canberra given its public service concentration — completed a whole-of-government deduplication framework under the Government Chief Digital Officer in late 2024. That framework is now referenced by some ACT policy staff as a potential model, though no formal adoption has been announced.

The cost dimension matters here. Cloud storage for large image files — particularly high-resolution scans and geospatial imagery common in federal departments like the Australian Bureau of Statistics and Geoscience Australia, both headquartered in the Belconnen and Symonston corridors respectively — runs at commercial rates that add up fast when duplication is systemic. Generic enterprise cloud contracts for Australian government entities typically price storage in tiers that make the first few terabytes cheap and the long tail expensive.

For public servants and researchers in Canberra navigating this right now, the practical upshot is straightforward: if your agency or institution has not yet run a deduplication audit ahead of the December 2026 cloud consolidation deadline, the window to do it cleanly is shrinking. Tools like open-source perceptual hashing libraries and vendor-provided deduplication modules built into platforms such as Microsoft Purview are available without major procurement hurdles. The agencies that acted early — the National Archives, ANU's digital teams — will spend the second half of 2026 refining systems rather than scrambling to build them.
