How Wollongong's Visual Archive Ended Up Full of Duplicates — and What's Being Done About It

Wollongong City Council's online image library contains thousands of duplicate photographs — some files appearing three or four times under different file names — a problem that staff have been working to address since at least late 2024, when a routine audit of the council's digital asset management system flagged the extent of the issue. The duplication problem is not unique to Wollongong, but its scale here reflects a decade of piecemeal digitisation across multiple departments, each uploading assets independently with no unified naming convention.

The timing matters. The Illawarra region is generating more visual content than ever before, driven by major infrastructure and industry transition projects. BlueScope Steel's green steel transition at Port Kembla, the Port Kembla Renewable Energy Zone precinct, and the ongoing development corridor along Flinders Street in the CBD have all produced large volumes of photography, drone footage stills, and architectural renders — all of which eventually end up in shared municipal and media repositories. When those repositories carry duplicate or mislabelled images, the downstream effects range from the mundane to the costly: planning documents referencing the wrong site photograph, media outlets publishing outdated construction images, and grant acquittal reports including visuals that don't match the project described.

How the Duplication Built Up Over a Decade

The roots of the problem stretch back to roughly 2014, when Wollongong City Council began digitising physical photograph collections held at the City Library on Crown Street. That process ran concurrently with staff uploading new digital images from events, site inspections, and communications campaigns — but into different folder structures and, in some cases, different platforms entirely. By the time the council migrated to its current content management system, staff inherited what one internal review document described as a fragmented legacy archive. The University of Wollongong's media unit encountered a parallel issue when it overhauled its brand assets ahead of the 2023 campus redevelopment campaign, discovering that the Innovation Campus at North Wollongong had been photographed under at least six different folder labels across three separate shared drives.

The practical consequence of duplicate images is rarely dramatic on any single day. The problem compounds. A development application for a site on Keira Street, for example, might draw on a site photograph that was uploaded twice — once correctly geocoded, once not — and staff selecting images under time pressure grab the wrong version. The error might not surface until a heritage or planning officer cross-checks the document weeks later. Multiply that across hundreds of applications annually and the administrative rework becomes significant.

Wollongong's situation also reflects broader pressures on local government digital infrastructure. The NSW Government's Digital Information Security Policy, updated in 2023, requires councils to maintain accurate metadata for all public-facing digital assets, but compliance timelines have varied considerably across the state's 128 local government areas.

The Path Toward a Cleaner System

The current remediation effort involves a phased review of the council's digital asset library, with priority given to images directly linked to planning, heritage, and public communications. Staff are cross-referencing upload dates, file hashes, and GPS metadata embedded in photographs to identify true duplicates versus images that are legitimately similar but distinct. The work is manual in parts and automated in others, using deduplication software that flags files with more than 95 per cent visual similarity for human review.

For residents and local organisations, the practical advice is straightforward: if you are submitting a development application, heritage nomination, or funding acquittal to any Wollongong City Council department, label your image files with the street address, date, and a short descriptor before uploading. The same applies to community groups submitting grant reports under the Illawarra Shoalhaven Regional Development Fund, which processes dozens of acquittals each financial year and relies on submitted imagery to verify project completion.

The archive will not be perfect by any fixed date — the council has not publicly committed to a completion milestone. But the audit work now underway represents the most systematic attempt to clean up Wollongong's visual record since the original digitisation push began twelve years ago.
