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

The ACT government holds tens of thousands of digital image files across its agencies — and a significant portion of them are duplicates. That's not a quirk unique to Canberra, but how the territory is managing the cleanup puts it in an instructive position alongside similarly sized administrative capitals grappling with the same bloat.

Duplicate image replacement — the process of identifying, consolidating and replacing redundant digital files across government content management systems — has become a quiet but costly headache for public sector IT departments globally. The trigger now is straightforward: cloud storage contracts are being renegotiated, digital accessibility standards are tightening under frameworks like the Web Content Accessibility Guidelines 2.2, and auditors are asking harder questions about what agencies are actually paying to store.

What Canberra Is Doing

The ACT's Digital, Data and Technology Solutions directorate has been running a structured audit of imagery held across agency websites since late 2025, with a particular focus on the ServiceCanberra portal and assets tied to the Access Canberra network. The audit covers image libraries used for public-facing communications, internal intranet systems and records held under the Territory Records Act 2002. Two institutions doing related work are the Australian National University's Digital Humanities Hub in Acton and the University of Canberra's Centre for Creative and Cultural Research in Bruce, both of which have flagged duplicate image management as a research and operational concern in their own right.

The practical problem is well understood by anyone who has worked in government communications on Northbourne Avenue or in the Civic precinct: the same photograph of a ministerial announcement gets uploaded by three different teams, renamed differently each time, and ends up stored across multiple platforms with no centralised metadata tagging. Multiply that across a decade of digital publishing and the volume becomes genuinely unmanageable without dedicated tooling.

Wellington, New Zealand — roughly comparable to Canberra in population and its function as a national capital dominated by public sector workers — began a formal duplicate asset consolidation program through its Department of Internal Affairs in 2023. According to that department's published annual report, the program reduced redundant digital file storage by roughly 34 percent across core ministry websites within eighteen months. Edinburgh's devolved government administration undertook a similar exercise in 2024 ahead of migrating to a new content management system, cutting image library size by approximately 40 percent before the migration date.

Where the Gaps Show

Canberra's challenge is structural. Unlike Wellington, which consolidated to a single CMS vendor across most ministries, ACT agencies run multiple platforms simultaneously — some dating to before 2015. The Suburban Land Agency, for example, operates different web infrastructure from Transport Canberra, which differs again from the health directorate. That fragmentation makes automated duplicate detection harder to run at scale without manual intervention.

The global benchmark tool of choice in 2025 and 2026 has been perceptual hashing software, which can identify near-identical images even when filenames and metadata differ. Ottawa's Treasury Board Secretariat adopted one such tool across federal departments in early 2026. The ACT has trialled comparable software within the Access Canberra environment but has not yet committed to a territory-wide rollout, according to documents tabled in the Legislative Assembly during the February 2026 budget estimates hearings.

For Canberrans working in the public service — the largest single employment cohort in the territory — the practical upshot matters at the agency level. Departments that haven't addressed duplicate imagery face slower website load times, accessibility compliance risks, and unnecessary storage costs at a time when the federal government is pressing agencies to reduce ICT expenditure under the shared-services agenda pursued through the Australian Public Service Commission.

The ACT's next move will likely come through the Digital Strategy refresh expected in the third quarter of 2026. If the directorate follows the Wellington model and sets measurable reduction targets — rather than leaving cleanup to individual agencies — Canberra could close the gap on its peer capitals within two budget cycles. Without that central mandate, the duplicate problem simply shifts files around without resolving the underlying fragmentation that created it.
