ACT Government's Digital Archives Hit by Duplicate Image Crisis — Here's What Changed This Week

The ACT Government's Digital Services Division confirmed this week it has completed the first phase of a territory-wide duplicate image remediation program, clearing more than 4,200 redundant image files from public-sector websites administered through the Canberra Connect portal. The work, which ran throughout June and concluded on July 4, targeted agency sites hosted on the shared ServiceNow and Squiz Matrix platforms used by more than a dozen directorates.

The timing matters. The ACT Legislative Assembly's Standing Committee on Administration and Procedure tabled a records management review in May that flagged digital asset duplication as a growing cost and compliance risk across government. That report pointed to storage overhead and broken accessibility metadata — alt-text fields stripped when images are duplicated by automated content management scripts — as the two most pressing problems. Friday's cleanup was a direct operational response.

What the Audit Found Across Canberra's Government Offices

The bulk of the duplicated files traced back to two migration events: the 2023 move of Transport Canberra's public information pages from an older Drupal system, and a 2024 content refresh of the ACT Health directorate's consumer-facing site on Civic Square. In both cases, automated import scripts created multiple copies of the same image assets without triggering deduplication checks. Staff at the Canberra Connect Service Centre on Northbourne Avenue had flagged the problem internally as early as last November, but a remediation schedule wasn't locked in until February's Digital Transformation Roadmap update.

The Australian National University's 3A Institute, which has a standing research partnership with the ACT Government on responsible data management, assisted in designing the audit taxonomy used to classify duplicate severity. Files were graded across three tiers: cosmetic duplicates with no metadata conflict, duplicates causing broken internal hyperlinks, and high-risk duplicates where conflicting alt-text descriptions were creating accessibility failures under the Web Content Accessibility Guidelines 2.1 standard. The third category — the most urgent — accounted for roughly 340 files.

University of Canberra's Centre for Computational Communication Research separately provided a file-fingerprinting tool adapted from academic image-matching software. That tool, running on ACT government infrastructure at the Civic precinct data centre, processed the backlog in eight days rather than the six weeks a manual review would have required.

What Residents and Public Servants Should Expect Next

For anyone who regularly uses ACT government websites — whether to access Transport Canberra timetables from a Gungahlin home or to pull planning documents for a development in Belconnen — the visible change will be minor. Some older cached pages may temporarily display broken image placeholders until browser caches clear, typically within 48 to 72 hours. The Digital Services Division advised users experiencing persistent display errors on the Canberra Connect portal to clear their browser cache or contact the service desk at the Northbourne Avenue centre directly.

Phase two of the remediation is scheduled to begin in late August and will cover the roughly 18 agency subsites that run on separate content management arrangements, including the ACT Education Directorate's school-level pages and the Environment, Planning and Sustainable Development Directorate's interactive mapping tools. That phase is budgeted at $210,000 under the existing Digital Transformation Roadmap allocation, according to the roadmap document published on the ACT Government open data portal in February 2026.

Longer term, the Digital Services Division flagged plans to enforce an automated deduplication check as a mandatory gate in the content publishing workflow — meaning no image file can be uploaded to a government site without first being checked against a central asset registry. That policy is expected to go to directorates for consultation in September. If adopted on the proposed timeline, it would take effect from January 1, 2027, applying to all new content published on Canberra Connect and its affiliated agency portals. The fix is procedural and unglamorous, but for a city whose workforce lives and dies by functional government systems, it is exactly the kind of infrastructure maintenance that tends to matter most.
