How Canberra's Public Sector Quietly Became Ground Zero for the Duplicate Image Problem

The ACT Government's Service Directorate confirmed earlier this year that a formal duplicate image replacement program was underway across its citizen-facing digital platforms, a quiet admission that decades of piecemeal content management had created a sprawling, redundant archive that no single team fully understood. The program targets websites, internal knowledge bases and public-record portals that together serve hundreds of thousands of Canberrans each year.

The timing matters. The federal government's broader Digital Transformation Agency push, centred on its myGov integration roadmap, has forced state and territory agencies to align their digital assets with national accessibility and metadata standards by the end of the 2026 financial year. ACT agencies that cannot demonstrate clean, tagged image libraries risk losing interoperability status — effectively cutting them off from shared federal data pipelines.

How the Backlog Built Up

The roots of the problem stretch back to the early 2000s, when ACT Government directorates began building their own content management systems independently. Transport Canberra, the Housing Authority, the Health Directorate and Access Canberra each procured separate platforms over a roughly 15-year period. Images — maps of Gungahlin growth corridors, photos of the Belconnen Arts Centre, renders of light rail Stage 2 alignments along Northbourne Avenue — were uploaded repeatedly across systems, often at different resolutions and with contradictory file names and alt-text descriptions.

The Australian National University's 3A Institute, based in the Acton precinct, published research in 2024 examining how large public-sector organisations accumulate what the researchers called "digital sediment" — layers of content added without corresponding deletion or deduplication protocols. The ACT Government's experience maps closely to that pattern. A document tabled in the ACT Legislative Assembly in March 2026 noted that one directorate's image repository had grown to more than 40,000 individual files, with internal audits estimating that fewer than 60 per cent were unique assets.

The University of Canberra's News and Media Research Centre, on Kirinari Street in Bruce, has separately tracked how government image mismanagement affects public communication quality — specifically the way duplicated or mislabelled images erode trust when citizens notice inconsistencies between published graphics and on-the-ground reality. Bus route maps showing pre-2019 infrastructure on current timetable pages are a recurring example.

What Replacement Actually Involves

Duplicate image replacement is not simply deleting copies. Each flagged image must be assessed for whether it is the canonical version, whether it is embedded in archived pages covered by the Territory Records Act 2002, and whether replacing it could break hyperlinks inside documents that are part of the public record. That legislative constraint is the main reason the process takes months, not weeks.

The ACT Digital Services team, operating out of offices in the Canberra CBD on London Circuit, is running the deduplication work in phases. The first phase, completed in late 2025, covered Access Canberra's service landing pages. Phase two, currently active, covers Transport Canberra's network maps and the planning visualisations tied to the Gungahlin to City light rail corridor. A third phase covering Health Directorate patient information pages is scheduled to begin in September 2026.

For public servants in Belconnen and Tuggeranong offices who manage content day-to-day, the practical effect is a new mandatory step in the content upload workflow: a hash-check tool that flags near-duplicate files before they are published. Staff have until October 31, 2026 to complete mandatory training through the ACT Public Service Learning Catalogue.

Citizens are unlikely to see dramatic changes on any single day. The visible result will accumulate gradually — sharper, correctly labelled maps, accessible alt-text that describes current rather than historical infrastructure, and load times on mobile devices that improve as bloated directories are trimmed. For a public service city where government digital touchpoints are part of everyday life, that slow improvement is the whole point.
