Canberra Agencies Race to Fix Duplicate Image Problem Swamping Government Websites This Week

Digital records managers across the ACT public service spent much of this week dealing with a problem that sounds mundane until you see the scale of it: thousands of duplicate image files clogging agency content management systems, breaking page layouts, and in some cases serving outdated or legally non-compliant imagery to the public. The issue surfaced prominently after a routine audit cycle flagged redundant assets across multiple federal and territory agency websites hosted through the Digital Transformation Agency's whole-of-government platform.

The timing is not accidental. A revised Web Content Accessibility Guidelines compliance target — WCAG 2.2 — applies to all Commonwealth-hosted public-facing websites from 1 July 2026. Duplicate images, particularly those lacking updated alt-text or correct metadata, are a direct accessibility failure under the standard. Agencies that have not resolved flagged assets face formal non-compliance status, which triggers reporting obligations to the Australian Government Information Management Office.

What Actually Happened This Week

The Australian National University's digital communications team confirmed internally on Monday that its web estate — spanning the Acton campus flagship site and several faculty microsites — had identified more than 400 redundant image entries during a content clean-up begun in late June. The university uses a Drupal-based CMS and the duplication problem stemmed in part from a migration carried out in early 2025, when legacy media library entries were bulk-imported without deduplication checks. Staff from the ANU Communications division spent Wednesday and Thursday manually reviewing flagged assets in the Acton campus administration precinct.

Across town at the University of Canberra's Bruce campus, the situation was similar. UC's digital team flagged the duplicate image replacement task as a priority item in its quarterly web governance review, a process tied to UC's broader Digital Experience Strategy. Staff there noted that image duplication had compounded after a website refresh rolled out ahead of the February 2026 semester intake.

For ACT Government agencies, the pressure point is the Access Canberra service portal, which serves residents across Gungahlin, Belconnen, and the inner south. The portal's content team — operating out of offices on Callam Street in Woden — began a structured duplicate asset replacement program on 30 June. The program targets approximately 1,200 flagged image records across the planning, transport, and licensing sections of the site.

Why Duplicate Images Are More Than a Housekeeping Issue

The practical consequences go beyond cluttered file libraries. Duplicate images with conflicting metadata confuse screen readers, the assistive technology used by an estimated one in six Australians living with some form of disability. When two versions of the same image exist — one with correct alt-text and one without — automated content delivery systems can serve either version, creating an unpredictable experience for users relying on those tools.

There is also a storage and cost dimension. Cloud hosting fees for government web infrastructure are billed against actual storage consumption. Redundant binary files — even image thumbnails — accumulate across years of content publishing. A 2024 audit of federal agency CMS environments, published by the Digital Transformation Agency, found that duplicate media assets accounted for between 15 and 22 per cent of total media library storage in surveyed systems. Cleaning those records has a direct budgetary benefit, particularly relevant as the Albanese government maintains pressure on agency operational budgets heading into the 2026-27 financial year.

Digital asset managers across the sector have been leaning on automated deduplication tools this week, with several ACT-based teams trialling a plugin built for the federal GovCMS platform. GovCMS, maintained by Salsa Digital under a whole-of-government contract, includes a media library module that does not natively prevent duplicate uploads — a gap that developers have noted in public GitHub issue threads since at least 2023.

For public servants navigating this themselves, the practical advice from digital governance specialists is consistent: run a hash-based duplicate check on your media library before replacing any files manually, update alt-text on the canonical version first, then unpublish rather than delete duplicates to preserve any inbound links. Agencies with Access Canberra-facing content should aim to resolve flagged assets before the next automated WCAG scan, scheduled for the week of 20 July 2026.
