Years of under-resourced digitisation, shifting council software contracts and pandemic-era shortcuts have left the city's official image archives riddled with duplicates — and the clean-up bill is only growing.
Townsville City Council's digital asset library contains at least 14,000 duplicate image files, a figure confirmed in an internal audit completed in March 2026 and obtained by The Daily Townsville. The problem did not appear overnight. It is the accumulated result of more than a decade of fragmented digitisation projects, three separate content management systems and a workforce that was asked to do more with less during the COVID-19 pandemic years.
The timing matters. Council is currently mid-way through a $4.2 million upgrade of its public-facing website and community engagement portal, a project managed by the Smart City office on Ogden Street. Contractors working on that upgrade flagged the duplicate problem in late 2025 when database migration scripts began throwing errors. What started as a technical footnote has since grown into a line item that threatens to push the project past its November 2026 completion deadline.
The roots of the problem stretch back to 2013, when Townsville City Council first moved from physical photograph filing to a centralised digital repository. That initial system, managed through a now-defunct Brisbane-based vendor, was replaced in 2018 with a Drupal-based platform. Staff transferred files manually — a process that was never audited for duplicates. Then in 2019, the floods hit. The recovery effort generated thousands of drone and ground-level photographs documenting damage across suburbs from Mundingburra to Cranbrook. Files were uploaded in bulk by at least six different departments, often without standardised naming conventions.
The pandemic compounded things. Between March 2020 and mid-2021, a reduced workforce at council's corporate services division continued uploading images to support community announcements and grant applications — including material related to the Townsville Hydrogen Hub feasibility work at the Port of Townsville — but the metadata tagging system was effectively abandoned as non-essential. By the time a new digital asset management policy was drafted in 2023, the damage was done.
Libraries and community organisations faced similar pressures. The Townsville City Libraries network, which runs branches including Central Library on Flinders Street and the Aitkenvale branch, began its own oral history digitisation program in 2021 under the $680,000 Local History Grant funded through State Library Queensland. Coordinators there say duplicate files also crept in when volunteer scanning teams uploaded images from the same physical collection on separate days without cross-checking against existing records.
Deduplication is not simply a matter of running a piece of software. Images taken seconds apart, or scanned from the same photograph at different resolutions, may be flagged as unique by basic hash-matching tools. The council's current contractor, engaged under a $210,000 digital services agreement signed in February 2026, is using a perceptual hashing method that compares visual similarity rather than just file size or name. Even so, human review is required for anything the algorithm rates as a borderline match — and the audit identified roughly 3,200 files in that borderline category.
The First Nations cultural materials held within the archive add another layer of complexity. Some images were collected during community consultation sessions tied to Queensland's treaty process and carry access restrictions that mean they cannot simply be merged or deleted without consent from the relevant community groups. Council's Indigenous Engagement Unit, based at the Townsville City Council administration building on Walker Street, is working with Traditional Owner representatives to review that subset of the archive separately.
Residents and local organisations that use council's image portal — including sporting clubs applying for the Active Townsville grants program and neighbourhood groups sourcing photos for suburb improvement proposals — should expect intermittent access issues between now and October as migration work continues. Council's Smart City office says a public-facing status page will be live by the end of July 2026. Anyone who has submitted imagery to council through an online form since January 2025 and is concerned about how their files are being handled can contact the corporate services team directly via the Walker Street office.
