How Canberra's Government Websites Ended Up Riddled With Duplicate Images — And Why It Took Years to Notice

The problem did not arrive overnight. Somewhere between the 2014 federal public service digitalisation push, two rounds of ACT government website consolidation, and the mass shift to remote work in 2020, Canberra's public-sector web estate quietly accumulated a sprawling library of duplicate images — the same photo of the Brindabella ranges appearing under seventeen different file names, the same headshot of a generic staff member stored across four separate Content Management System instances.

Duplicate image replacement — the systematic process of identifying, deduplicating, and substituting redundant visual assets across digital platforms — has become a live operational issue for agencies clustered along Constitution Avenue and London Circuit in 2026, not a theoretical one. The question is how the territory and Commonwealth arrived here, and what it actually costs.

The Migration Era Left a Mess

The roots trace back to the Digital Transformation Agency's early years. When the DTA, headquartered in Barton, began pushing Commonwealth departments toward the australia.gov.au and eventually the GOV.AU platform model from around 2016 onward, agencies migrated content in bulk rather than curating it. Images were exported from legacy Drupal and SharePoint systems and re-imported wholesale, with automated scripts that generated new file identifiers for assets already in the system. The result was duplication baked in at the infrastructure level before a single public servant had manually uploaded a second copy of anything.

The ACT government ran its own parallel process. The transition of ACT Health, Access Canberra, and Transport Canberra onto the unified act.gov.au platform — a consolidation that stretched across multiple budget cycles during the late 2010s — replicated the same pattern. Site managers at Dickson and Tuggeranong service centres were asked to maintain local content under tight resourcing, often re-uploading images they could not locate in a shared library they had never been trained to search effectively.

By the time agencies began serious content audits in 2024 and 2025, some departments were reporting internal storage bloat in the hundreds of gigabytes attributable purely to image duplication. That figure — drawn from internal digital asset reviews referenced in budget estimates hearings at the ACT Legislative Assembly on Civic Square — translates to real hosting and bandwidth costs at a time when the territory is simultaneously funding Light Rail Stage 2B toward Commonwealth Park and managing constrained operating budgets.

Why 2026 Is the Inflection Point

Two things changed this year. First, the Commonwealth's updated Web Accessibility Framework, which came into effect in March 2026, requires agencies to audit all visual assets for alt-text compliance — a process that, in practice, forces a full image inventory. You cannot write accurate alt-text for an image without first knowing what images you actually have. Second, the ACT government's new Digital Canberra Action Plan, released in May 2026, set explicit targets for platform performance and page-load times on high-traffic services including Access Canberra's online booking system, which residents in Gungahlin and Belconnen use heavily given the growth in those suburbs and the pressure on in-person service centres.

Those two pressures — federal compliance and local performance — have made duplicate image replacement a line item rather than a background maintenance task. Technology teams at agencies in the Nishi building on NewActon and at the ACT Government offices on Moore Street in the city have been allocated specific sprint cycles in 2026 to work through asset libraries using automated deduplication tools, flagging files for human review before deletion or consolidation.

The practical path forward involves three steps that digital teams across the city are now working through: a full CMS image audit using hash-matching software to identify bit-identical files, a secondary review for near-duplicates such as differently cropped versions of the same photograph, and a controlled replacement workflow that updates all content references before the original duplicate is retired. Agencies that have begun the process report the first audit phase alone uncovers redundancies at a ratio that surprises even experienced web managers. The work is unglamorous. It is also, at this point, overdue.
