How Canberra's Government Websites Ended Up Drowning in Duplicate Images — and What It Cost

Thousands of duplicate image files are clogging the content management systems used by ACT Government agencies, inflating hosting costs and slowing page-load times across dozens of public-facing websites — and the problem did not happen overnight.

The issue matters now because the ACT Government is mid-way through a digital consolidation program aimed at moving more than 40 agency websites onto a unified platform by the end of 2026. That migration, managed through the Digital, Data and Technology Solutions (DDTS) division of the ACT Government Directorate, has forced teams to confront asset libraries that in some cases contain four or five identical versions of the same photograph — each uploaded separately, renamed slightly differently, and never reconciled.

How the Duplication Built Up

The roots go back to roughly 2014, when individual directorates began running their own CivicPlus and WordPress installations without a shared media library or central governance policy. The City Renewal Authority, for instance, operated a content workflow entirely separate from Transport Canberra and City Services, even when both agencies were publishing images of the same infrastructure projects along Northbourne Avenue or in the Gungahlin town centre. Every time a communications officer left and a new one started, the default move was to re-upload stock images rather than search an unfamiliar asset library.

The National Capital Authority, which controls its own web presence covering Commonwealth land including Parkes Way and the Parliamentary Triangle, had similar habits. Its image archive, separate from ACT Government systems, also accumulated near-identical aerial shots of Lake Burley Griffin — a recurring headache for web managers trying to coordinate joint campaigns around events like Floriade or the Enlighten festival.

The Australian National University flagged a version of the same problem internally as early as 2019, when its marketing and communications team audited the ANU website and found substantial duplication in the media library after years of faculty-level uploads. The university moved to a DAM — digital asset management — system through a phased rollout that concluded in 2022. That shift has since been cited informally in ACT public service circles as a local case study worth examining, though no formal government review has publicly referenced it.

The Scale of the Problem

Getting hard numbers out of the ACT Government on this is not straightforward. The DDTS division has not published a consolidated audit. However, the pattern is consistent with what digital archivists across Australian state governments have documented: a 2023 report by the Australian Government Information Management Office noted that unmanaged media assets across federal agencies were contributing to storage expenditure that agencies themselves could not accurately account for. That finding applies to Commonwealth entities operating in Canberra, including several with large public-facing websites based on Edinburgh Avenue and Constitution Avenue.

At a practical level, the duplication problem adds real costs. Commercial cloud storage for government-grade hosting in Australia typically runs between $0.025 and $0.08 per gigabyte per month depending on the provider and redundancy tier. For an agency sitting on tens of thousands of unmanaged image files — many of them uncompressed TIFFs or high-resolution PNGs — that adds up across a financial year. It also degrades performance: page-load speeds on sites stuffed with multiple versions of the same hero image draw complaints that often get misattributed to bandwidth or server issues rather than asset bloat.

The DDTS consolidation program, if it proceeds on schedule, will require each participating agency to run a duplicate-detection pass before content migrates. Agencies have been advised to use automated deduplication tools as part of the pre-migration checklist. Belconnen-based community service agencies that host their own sites through ACT Community Services grants face a smaller but structurally identical problem — volunteers uploading event photos repeatedly across different pages.

The practical takeaway for Canberra organisations running their own content systems is simple: a scheduled quarterly audit of the media library, combined with a clear naming convention enforced at the point of upload, prevents most of the duplication before it compounds. That is a lesson the ACT public service is learning now at scale, and at cost, rather than at the start.
