How Townsville's Public Record Problem Got This Bad: The Story Behind the Duplicate Image PushUpdated

Townsville City Council's digital asset library contains thousands of photographs taken since the early 2000s, and by the council's own internal audit process — which began in earnest in late 2025 — a significant portion are duplicates, near-duplicates or mislabelled files that have quietly multiplied across shared drives for more than a decade. The council's Information Management Unit is now running a structured duplicate image replacement program to address the problem before a broader digitisation push scheduled for the second half of 2026.

The timing matters. Townsville is approaching a critical phase in several long-running infrastructure and heritage projects — including updated flood resilience mapping across the Bohle Plains corridor and digital cataloguing of First Nations cultural materials held in partnership with the Townsville Aboriginal and Islander Health Service and local land councils. Dirty data in image archives doesn't just waste storage. It causes real problems when planners, engineers and community representatives try to pull accurate photographic evidence for planning applications, insurance assessments or formal submissions to the Queensland treaty process.

How the Backlog Built Up

The roots of the problem go back at least to 2011, when the council began migrating physical photograph collections to digital formats ahead of major infrastructure upgrades along Ross River. That process accelerated after the January 2019 floods, when rapid documentation of damage to properties across Idalia, Hermit Park and the CBD generated thousands of images in a matter of weeks. Staff uploaded files from multiple devices — smartphones, council cameras, contractor equipment — into the same shared repository without a unified naming convention. The same photograph of, say, a collapsed fence on Bundock Street sometimes appears under four different file names.

The pandemic made it worse. Between March 2020 and late 2021, the council's Records and Information Services team operated with reduced staffing, and routine deduplication checks that had previously run quarterly were suspended. By the time normal operations resumed at the Sturt Street civic precinct, the backlog had compounded. A 2024 Queensland State Archives review of local government digital record-keeping — which assessed councils across the state — flagged several councils, including those in North Queensland, for incomplete metadata and file integrity issues, though it did not name individual councils in its public summary.

James Cook University's eResearch Centre, based on Ring Road in the university's Douglas campus, has worked with council on smaller-scale data hygiene projects since 2022. That relationship is part of why the current duplicate image replacement effort looks more methodical than previous attempts. The program involves hashing algorithms that identify visually identical or near-identical files, followed by manual review of flagged images by council archivists before any file is deleted or replaced. The North Queensland Cowboys Community Foundation's archive of community event photographs — donated to the council's local history collection — was among the collections processed in an early pilot run earlier this year.

What the Cleanup Actually Involves

Duplicate image replacement is not simply deleting copies. Where an original high-resolution source file exists, the lower-quality duplicate is replaced with a properly labelled version linked to correct metadata — location, date, project reference, copyright status. For images where the original cannot be confirmed, both files are quarantined pending review rather than deleted outright. That conservative approach reflects hard lessons from 2023, when a separate council data project accidentally removed the sole digital copies of several photographs documenting the post-flood restoration of the Jezzine Barracks foreshore precinct.

The full program is expected to run through to March 2027. Council has allocated resources from its existing Information Technology budget cycle, which runs on a financial year basis from July 2026. Community organisations that have donated photographic material to the Townsville City Libraries local history collection — held primarily at the Aitkenvale branch on Bundock Street — are being contacted individually if their donated images are caught in the deduplication sweep.

Anyone who has provided photographs to council through a flood insurance claim, a heritage nomination, or a community grant application in the past five years and wants to confirm their images are correctly catalogued can contact the Records and Information Services team directly through the council's online service portal at townsville.qld.gov.au.
