Canberra's Duplicate Image Problem: How the Capital Stacks Up Against Cities Getting It Right

The ACT government's digital services directorate is sitting on a problem familiar to every large bureaucracy that built its online presence in layers over two decades: thousands of duplicate images scattered across agency websites, internal document management systems, and public-facing portals, eating storage, slowing load times, and creating compliance headaches under the Australian Government's Web Accessibility National Transition Strategy.

It's a mundane-sounding issue, but the timing matters. The federal government's broader digital transformation push — centred on the Australian Public Service Commission's ongoing workforce reform agenda — has put pressure on every Canberra-based agency to audit and modernise digital assets before a rolling series of platform migrations planned through 2027. Duplicate image libraries are one of the clearest bottlenecks in those migrations.

What's Actually Happening in Canberra

The Australian National University's digital infrastructure team completed a content audit of its public web properties in late 2025, identifying redundant image files across more than 40 faculty and research-unit microsites. The University of Canberra has undertaken similar work through its ICT Renewal Program, consolidating assets from the Bruce campus's sprawling departmental web presence into a centralised digital asset management system. Neither institution has published full findings, but the scope of the problem at both Acton and Bruce reflects what agencies across Civic and Barton are dealing with at scale.

Within the ACT public service, the Digital, Data and Technology Solutions division — which sits inside the Chief Minister, Treasury and Economy Directorate on London Circuit — has been developing a whole-of-government digital asset policy since at least mid-2025. The policy is expected to mandate metadata standards for image uploads across directorate websites, a step that should mechanically prevent new duplicates accumulating. Whether it addresses the existing backlog is less clear.

Canberra's challenge is structural. Unlike a commercial organisation that controls its own stack, the ACT government operates across more than a dozen directorates, each with its own content management system history, vendor relationships, and upload habits built up since at least 2008 when the first wave of government CMS platforms rolled out across Australia. The result is a digital estate where the same stock photograph of, say, a Gungahlin town square or a light rail tram on Flemington Road can exist in six slightly different compressed versions across three different servers.

How Other Cities Are Handling It

Amsterdam's municipal digital team completed a city-wide image deduplication project in 2023, centralising assets from 22 departments into a single DAM platform built on open-source infrastructure. The project reportedly cut image storage costs by roughly 40 percent and reduced average page load times on amsterdam.nl by 1.2 seconds — figures the city published in its 2024 digital annual report. Wellington City Council in New Zealand adopted a similar consolidated asset library approach as part of its Digital Wellington strategy, completed in stages between 2022 and 2024, with content editors across all departments now working from a single approved image repository.

Helsinki, often cited as a benchmark for government digital services, embedded deduplication rules directly into its procurement standards for content management systems from 2021 onward, meaning the problem was largely engineered out before it could recur. Canberra has not yet reached that stage. The ACT's draft digital asset policy, as understood from publicly available directorate budget papers for 2025-26, remains in consultation rather than enforcement.

The practical consequence for Canberrans is subtle but real. Government websites that carry duplicate, unoptimised images load more slowly on mobile networks — a particular issue in outer growth suburbs like Gungahlin and Belconnen where 4G rather than fixed broadband remains common for a portion of residents. Accessibility audits also flag duplicate and unlabelled images as barriers for screen-reader users, a compliance exposure for agencies subject to the Disability Discrimination Act 1992.

For public servants navigating their own agency's content systems, the most immediate practical step is to raise the asset audit question with their directorate's digital or communications team before the next CMS migration window opens. Those migrations, tied to the broader APS digital modernisation timeline, are scheduled to begin rolling across agencies from early 2027. Agencies that arrive at that point with unresolved duplicate libraries will face higher migration costs and longer timelines. Amsterdam and Wellington cleared that problem before the migration. Canberra is still working on it.
