Canberra's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

Thousands of duplicate images are sitting inside the digital archives of ACT government agencies, costing storage budgets and creating compliance headaches that auditors have flagged as a growing liability. The problem is not new, but a convergence of factors — a July 2026 deadline for agencies to align with the ACT Digital Strategy's updated data governance framework, rising cloud storage costs, and a workforce that shifted heavily to remote tools during the pandemic — has pushed the issue to the top of the agenda for chief information officers across the territory.

The practical stakes are real. When multiple versions of the same image exist across shared drives, content management systems and cloud repositories, staff waste time verifying which file is authoritative. For agencies handling sensitive materials — think planning maps for the Molonglo Valley development corridor, or infrastructure photography tied to the Capital Metro light rail Stage 2 documentation — a duplicate can mean the wrong version gets attached to a formal submission or published on a public portal.

Who Carries the Problem and Where It Sits

The ACT's Digital, Data and Technology Solutions directorate, based in Canberra's city centre on Constitution Avenue, is the body responsible for setting standards across agency systems. Under the ACT Government's Digital Strategy 2025-2028, directorates are expected to conduct annual data quality audits, but enforcement has been inconsistent. The Australian National University's Digital Collections team in Acton and the University of Canberra's library services in Bruce have both developed internal deduplication workflows, though those sit outside the government's own procurement and compliance obligations.

Inside agencies, the problem is typically spread across at least three separate silos: legacy on-premises servers that predate the government's Microsoft 365 migration, SharePoint Online repositories that staff populated quickly during the 2020-2022 remote-work surge, and departmental content management systems that were never fully integrated with central storage. Canberra's public service workforce — which accounts for roughly 40 percent of the ACT's employed population — generates a significant volume of digital assets tied to federal and territory projects simultaneously, compounding the duplication risk whenever staff move between agencies or contractors copy files between environments.

Commercial deduplication tools licensed through the government's whole-of-government procurement panel are available from vendors including Iron Mountain and Veritas, with enterprise licensing costs for mid-sized agencies typically running between $80,000 and $200,000 annually depending on data volume. Some agencies have opted for built-in Microsoft Purview features already included in their existing Microsoft 365 E3 or E5 licences rather than procuring standalone tools — a decision that cuts cost but limits the depth of image-specific analysis the software can perform.

The Decisions That Will Define the Outcome

Three choices now face agency CIOs and the directorate. First: whether to run deduplication as a one-time remediation project or embed it as a continuous automated process. A remediation sprint is cheaper upfront but recreates the backlog within 18 to 24 months without policy changes to how staff save and share files. Second: which files get deleted versus archived. For images tied to planning decisions — including records for the Gungahlin town centre expansion and the West Belconnen development — deletion without archival sign-off from the ACT Territory Records Office on Rudd Street could breach the Territory Records Act 2002. Third: who pays. Treasury has not yet signalled whether the July 2026 data governance compliance push will come with additional funding or require agencies to absorb costs within existing appropriations.

The directorate is expected to issue updated technical guidance before the end of July. Agencies that miss the compliance window face inclusion on the ACT Auditor-General's watchlist, which publicly names underperforming directorates in its annual performance auditing reports. For CIOs already managing the demands of the light rail Stage 2 documentation requirements and housing-growth data for Belconnen and Gungahlin, the timing is tight. Getting this right means auditing what you have, choosing a tool architecture that fits existing licensing, and locking in a records-authority sign-off process before a single file gets permanently deleted.
