How Townsville's public image archive ended up full of duplicates — and what's being done about itUpdated

Townsville City Council's digital asset management system contains more than 14,000 images — and by the council's own internal audit completed in March 2026, roughly 3,400 of them are duplicates. The finding triggered a formal duplicate-image replacement project that is now midway through its remediation phase, with a completion target of October 31 this year.

The problem didn't appear overnight. It is the accumulated result of at least a decade of inconsistent file-handling across multiple council departments, two separate content management platform migrations, and the disruption caused by the February 2019 floods, when urgent communications demands saw dozens of staff uploading imagery with no standardised naming conventions and no central gatekeeper. That flood response period alone accounts for an estimated 900 duplicate or near-duplicate files still sitting in the system, according to the audit summary tabled at the council's Corporate Services Committee in April.

A decade of siloed uploads

Before 2021, Townsville City Council operated at least three separate image repositories simultaneously — one sitting inside the old Civica Authority records system used by the planning directorate on Walker Street, one maintained by the communications team at the Townsville City Council administration building on Walker Street, and a third managed independently by Townsville Water. When the council migrated to its current enterprise content management platform in late 2021, all three libraries were bulk-imported rather than cleaned and reconciled first. That decision, made under time pressure during the broader digital transformation program, is now widely acknowledged internally as the root cause of the duplicate stockpile.

The Ross River Dam precinct imagery is among the worst-affected collections. Because Townsville Water ran its own communications function for years before closer integration with the broader council structure, photos of the dam wall, the Aplins Weir outlet and the Gleeson's Weir fish ladder were uploaded repeatedly across different folder structures, often with slightly varied filenames to indicate different resolutions or crop ratios. The audit identified 212 duplicate sets within the dam and water infrastructure category alone.

Community events photography tells a similar story. Images from the Strand Ephemera Festival, the Pacific Festival held annually at Murray Stadium, and NAIDOC Week activities at Jezzine Barracks were frequently submitted by multiple council officers who attended the same event with different cameras. Without a post-event deduplication step in the workflow, every version went live in the system.

What the fix actually involves

The replacement project is not simply a delete-and-move-on exercise. Council's Digital Services team, working alongside the Communications and Engagement branch, is using a combination of automated hash-matching software and manual review to identify true duplicates versus images that look similar but capture different moments. The distinction matters because the council's legal obligations under the Queensland Public Records Act 2002 mean certain images taken at official proceedings must be retained even when they appear redundant.

Automated tools have handled approximately 60 per cent of the identified duplicates since the project formally kicked off in May. The remaining 40 per cent require human review, which is where the timeline becomes tight. The council has allocated $47,000 from its 2025-26 IT operational budget to cover contractor hours for that manual phase, with an additional $12,000 earmarked for staff training on the revised upload protocols that will go live once the clean library is in place.

Those new protocols include mandatory keyword tagging at the point of upload, a single-entry-point submission form for all photography submitted by external contractors — including the firms engaged for major infrastructure shoots at the Port of Townsville and the Townsville Stadium — and a quarterly audit cycle replacing the current ad hoc approach.

For residents and community organisations that regularly request images from council for local publications, newsletters or project documentation, the practical advice right now is to hold off on bulk requests until November, when the cleaned archive is expected to go live on the council's online media portal. Requests lodged before then will still be fulfilled, but staff have flagged response times may be slower than usual through August and September as the manual review work competes for the same staff bandwidth.
