Wollongong City Council's digital asset library contains thousands of duplicate image files spread across planning, heritage and community engagement departments — and the people tasked with managing those records say the problem has grown large enough to affect how development applications are assessed and how public documents are published online.
The issue surfaced publicly this week when the council's own technology and information governance unit flagged it in a quarterly report tabled at Tuesday's ordinary meeting. The report did not specify an exact file count, but described the duplication backlog as a "significant administrative burden" requiring dedicated remediation resources before the end of the 2026–27 financial year.
The timing matters. Wollongong is mid-way through one of the most intensive planning periods in its recent history. The Port Kembla Renewable Energy Zone precinct, the BlueScope industrial transition corridor along Springhill Road, and new medium-density housing proposals stretching from Fairy Meadow to Warrawong all depend on accurate, version-controlled photographic and mapping records. When duplicate images carry different metadata or conflicting timestamps, planners and heritage officers can end up working from different versions of the same site.
Why Duplication Happens — and Why It's Getting Worse
Digital asset specialists say the root cause is rarely malicious and almost always structural. Departments operating separate content management systems — a common arrangement in large councils — tend to re-upload images rather than link to a shared repository. The Wollongong council runs at least four distinct platforms that handle image assets, including its planning portal, the Illawarra Shoalhaven Regional Development Fund project tracker, the council's public-facing website, and an internal document management system used by heritage and building surveyors.
University of Wollongong researchers in the Faculty of Engineering and Information Sciences have studied similar problems in local government contexts across New South Wales. Their work, published through the university's Smart Infrastructure Facility on Northfields Avenue, points to annual remediation costs that can run into tens of thousands of dollars for mid-sized councils once staff time, storage overhead and audit expenses are factored in. The faculty has not published Wollongong-specific figures, but the general framework applies directly to a council of this size and complexity.
Representatives from the NSW Information and Privacy Commission have previously noted — in general guidance documents available on the commission's website — that duplicate records in public sector systems can create disclosure risks under the Government Information (Public Access) Act 2009, particularly where different versions of an image might be released in response to separate access requests.
Local Institutions Flagging Practical Consequences
The Illawarra Historical Society, based in Market Street in the CBD, maintains its own photographic archive of more than 40,000 images documenting the region from the late nineteenth century onwards. The society's digitisation program, which began in earnest around 2019, has had to develop its own deduplication protocols precisely because donated collections frequently arrive with images replicated across multiple formats and resolutions.
Heritage consultants working on projects near the Wollongong Courthouse precinct on Kembla Street have raised the issue in a different context — noting that when council heritage registers contain duplicate image entries for the same building at different dates, it creates ambiguity about which record is authoritative for development consent purposes.
The council's technology team is understood to be evaluating at least two commercial deduplication platforms, with a decision expected before October 2026. Any procurement above $250,000 would require a full tender process under council's existing procurement policy.
For residents and developers dealing with council systems in the meantime, the practical advice from information management professionals is consistent: when lodging development applications or heritage assessments through the council's online portal, include explicit file naming conventions and metadata in any image submissions, and keep a local copy of every file as lodged. That creates a clear record if questions later arise about which version of an image was current at the time of assessment.
The council is expected to provide a further update on its remediation timeline at the August ordinary meeting.
