How Canberra Is Tackling Duplicate Image Replacement—And Where It Stacks Up Against Peer Cities

The ACT government's Digital Canberra unit is midway through a systematic audit of its public-facing web assets, targeting the sprawling problem of duplicate and placeholder images that have accumulated across agency websites since at least 2018. The exercise, which spans more than 40 government domains, reflects a wider reckoning among capital cities about the hidden costs of poor digital asset management—costs that can blow out accessibility compliance budgets and erode public trust in official online services.

The timing is pointed. Federal agencies headquartered in Canberra—clustered along Northbourne Avenue and in the Barton precinct—are simultaneously under pressure from the Australian Government's Digital Transformation Agency to meet updated Web Content Accessibility Guidelines by the end of 2026. Duplicate images, particularly those carrying identical or missing alt-text, are a known sticking point for screen-reader users and directly affect compliance scores. The convergence of a territory-level audit and federal accessibility deadlines has pushed the issue to the top of the agenda in a city where public-sector workers make up a disproportionate share of the population.

What Canberra Is Actually Doing

The ACT's current approach centres on a two-phase process managed out of the Canberra Connect service portal team, based in Civic. Phase one, running since February 2026, involves automated scanning tools that flag repeated image hashes across agency content management systems. Phase two, scheduled to begin in September, will assign remediation tasks to individual agency web teams, with replacement images sourced from a central library maintained by the ACT Government's Design System repository. The Australian National University's 3A Institute in Acton has been consulted on the project's ethical dimensions—specifically around which stock images reinforce narrow demographic representations when substituted in bulk.

Gungahlin and Belconnen, the territory's fastest-growing suburbs, are the most visible test cases. Both town centre websites, which carry community services information, event listings, and planning updates, were identified in the February scan as carrying high rates of duplicated hero images—in some cases the same stock photograph appearing across more than a dozen separate pages. University of Canberra researchers in the Faculty of Arts and Design flagged this pattern in a report circulated to the ACT's Chief Digital Officer's office in March 2026, noting that homogeneous imagery undermines the sense that different suburbs have distinct identities.

How Canberra Compares Globally

Wellington, New Zealand—a comparable capital-city government hub with a population roughly similar to Canberra's—completed a full duplicate image audit of its council web infrastructure in late 2024 and replaced more than 8,000 images across 23 microsites, at a reported project cost of NZ$340,000. Edinburgh, Scotland, undertook a similar exercise for its City of Edinburgh Council in 2023, driven partly by a Scottish Government accessibility directive. Both cities opted for centralised image libraries with mandatory metadata tagging—a model Canberra's Digital Canberra unit is now explicitly benchmarking against, according to documents released under ACT FOI in May 2026.

Ottawa, Canada—another federal capital with a dominant public-service workforce—has taken a decentralised approach, leaving duplicate image management to individual departments. That model has drawn criticism from Canada's Treasury Board Secretariat, which noted in its 2025 digital services review that inconsistent image standards across departmental sites created measurable disparities in page-load times and accessibility scores. Canberra's more centralised model, though slower to implement, appears better positioned to avoid that fragmentation.

The practical stakes are real. Poor image asset management contributes to slower page loads; a 2024 analysis by the Web Almanac project found that unoptimised or duplicated images accounted for an average of 22 percent of avoidable page weight on government websites globally. For Canberra residents relying on mobile connections in outer suburbs like Tuggeranong or along the Gungahlin corridor, that overhead is not trivial.

The ACT government's phase-two remediation is due to begin in September 2026, with a full compliance report expected by March 2027. Web managers at territory agencies have been advised to hold off on large-scale image uploads until the central library is operational. For now, Canberra sits ahead of Ottawa but behind Wellington—a position the Digital Canberra team will want to close before the federal accessibility deadline arrives.
