How Canberra Handles Duplicate Digital Records Compared to Cities That Have Already Felt the Pain

The ACT government confirmed earlier this year that its shared digital asset repositories — used by agencies ranging from Transport Canberra to the ACT Health directorate — contained significant volumes of duplicate image files accumulated over more than a decade of fragmented IT procurement. The problem is not unique to Canberra, but the city's peculiar density of government computing infrastructure makes it an instructive case study in how jurisdictions are responding.

Duplicate image replacement — the systematic process of identifying, consolidating and replacing redundant digital files across enterprise systems — has quietly become one of the more consequential data governance challenges for public administrations. The trigger is partly financial: cloud storage costs have risen sharply across Australian government contracts since 2023, and partly legal, with the federal government's updated data retention framework placing new obligations on agencies to know exactly what files they hold and why.

Canberra's Particular Problem

The ACT's Digital, Data and Technology Solutions division, which operates under the Chief Minister, Treasury and Economic Development Directorate on London Circuit in Civic, has been coordinating a whole-of-government audit of digital asset holdings since late 2025. The exercise covers imagery held in document management systems, planning databases and health records platforms. Marcus Clarke Street-based agencies sharing infrastructure with the Australian National Audit Office have also been drawn into the review given overlapping network arrangements.

The Australian National University's 3A Institute, based on the Acton campus, has separately been examining the governance dimensions of duplicate data at scale, looking at how computational systems inherit and replicate errors — including image duplication — when agencies bolt new platforms onto legacy ones without proper deduplication protocols. Their work is not specific to ACT government systems, but its findings are directly relevant to the challenge Canberra administrators face.

Gungahlin and Belconnen, Canberra's fastest-growing suburban corridors, have generated particularly large volumes of planning and land-use imagery over the past five years as development applications surged. The ACT Planning directorate's mapping and imagery holdings are among the largest in the territory's digital estate, according to budget papers tabled in the ACT Legislative Assembly in May 2026, which referenced a territory-wide data management reform program allocated funding in the 2025-26 budget cycle.

What Comparable Cities Are Doing

Wellington, New Zealand — frequently benchmarked against Canberra given its similar size, public service-dominated workforce and capital city status — completed a whole-of-government deduplication program in 2024. The New Zealand government's digital office reported at the time that the exercise freed up substantial storage capacity across central agency systems, though Canberra administrators have noted that Wellington's IT consolidation started from a more unified base, having standardised on a single cloud platform earlier than Australian federal agencies.

Edinburgh, which administers Scottish Government digital assets for a population base comparable to Canberra's broader metropolitan region, took a different approach — deploying automated hash-matching tools across its records management system in 2023 rather than conducting manual audits. The Scottish approach was faster but generated disputes about which version of a duplicated image was the authoritative original, a problem Canberra's reviewers are explicitly trying to avoid by establishing provenance rules before running any automated tools.

Singapore's Government Technology Agency, GovTech, published a framework in early 2026 for managing image asset integrity across multi-agency platforms, and the ACT's digital division has referenced that framework in internal planning documents released under freedom of information requests lodged by community groups.

For Canberra public servants who interact daily with shared drives and document systems — particularly those in the large Tuggeranong and Woden office precincts — the practical upshot is likely to be a period of system migration and temporary access restrictions as deduplication tools run. Agencies have been advised to maintain local copies of critical working documents through the second half of 2026. The broader reform, if completed on the timeline indicated in the May budget papers, would position Canberra ahead of most comparable capital cities in data hygiene — a quiet but consequential achievement in a town where digital infrastructure underpins almost everything the government does.
