ACT Government's Duplicate Image Problem: What Happened This Week

The ACT Government's Digital Records Unit flagged this week that a routine audit of shared image libraries across multiple directorates has uncovered an estimated 40,000-plus duplicate image files sitting across departmental servers — redundant copies that have been accumulating, in some cases, since the migration to centralised cloud storage began in late 2023. The discovery has pushed the issue from a low-priority IT task to an active line item in agency budget reviews.

The timing matters. The ACT is mid-way through a broader digital modernisation push, and storage costs are real. Cloud hosting for government data, according to procurement benchmarks published by the Australian Government's Digital Transformation Agency, runs at a meaningful per-gigabyte cost when multiplied across dozens of agencies and hundreds of staff uploading assets daily. Duplicate image bloat is not a cosmetic problem — it slows search functions, inflates backup windows, and can create version-control confusion when outdated images remain accessible alongside current ones.

Where the Problem Is Concentrated

Two agencies are at the centre of this week's review. The ACT Health Directorate, which operates out of offices on Bowes Street in Phillip, manages an extensive library of public health campaign imagery — materials distributed to clinics, community centres, and digital platforms across the territory. Staff there have been cross-uploading assets between a legacy content management system and the newer Whole of Government Digital Asset Platform, a process that apparently generated a significant volume of near-identical files without automatic deduplication running on either end.

The second agency drawing scrutiny is Transport Canberra and City Services, whose communications team on Callam Street in Fyshwick has been producing regular image updates tied to Light Rail Stage 2 construction milestones. Multiple project photographers have been uploading shoot outputs directly to shared drives, with no central deduplication step in the workflow. The result: hundreds of images of the same Flemington Road corridor works existing in three or four slightly different export sizes, each stored as a distinct file.

The ACT Government's Digital Records Unit, housed within the Chief Minister, Treasury and Economic Development Directorate, is understood to have begun a remediation project this week using automated deduplication software. No contract value for that work has been publicly published as of 4 July 2026.

What Deduplication Actually Involves

The process is more involved than simply running a script. Staff must verify that the "original" version identified by the software is actually the highest-quality or most current asset before deletion proceeds. In some cases, multiple departments have independently edited the same source image — adjusting crops or colour profiles for different publication contexts — meaning apparent duplicates are not legally interchangeable. The audit team is understood to be working through a three-tier classification: exact duplicates safe for immediate deletion, near-duplicates requiring human review, and edited variants to be retained under separate file naming conventions.

For context, the Australian National University's IT governance framework — published on the ANU website and covering its own substantial digital asset library — recommends deduplication audits at minimum annually for any repository exceeding 500 gigabytes. The University of Canberra has a similar policy embedded in its Digital Asset Management Guidelines. Both institutions flag that delays in deduplication compound geometrically: the longer it runs unchecked, the more manual verification hours the eventual clean-up requires.

Public servants at agencies affected by this week's review have been advised not to delete any image files independently while the audit is underway. A guidance note circulated internally this week asks staff to flag any image they believe is a duplicate to their directorate's records officer rather than removing it themselves — a precaution against accidentally deleting the only high-resolution copy of a file that exists in the government's possession.

The remediation work is expected to run through August. Agencies will then be asked to adopt a standardised upload protocol, including mandatory metadata tagging at point of upload, designed to prevent the same accumulation occurring again. Whether that protocol will be mandated territory-wide or left to individual directorates to adopt remains, as of this week, an open question within the Digital Records Unit's working group.
