Wollongong's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

Wollongong City Council's library and cultural heritage division is sitting on a decision that will shape how the region's digital archives look for decades. A systematic audit of the Illawarra Regional Information Service database — which holds tens of thousands of photographs, maps and scanned documents — has identified a substantial volume of duplicate image records that are clogging the system, complicating public access and drawing down limited storage resources.

The timing is not accidental. Across New South Wales, regional councils have been under pressure since mid-2025 to bring their digital collections into compliance with the State Records Act ahead of a revised compliance review cycle beginning in September 2026. For Wollongong, a city managing competing budget demands from the Crown Street Mall precinct redevelopment, the ongoing Keiraville social housing push and the broader Port Kembla renewable energy zone transition, finding the staff hours and budget to tackle a digital housekeeping problem ranks low on instinct but high on consequence.

What the Backlog Actually Means

Duplicate image records are not simply an annoyance. When a researcher at the University of Wollongong's Engaging Communities research unit tries to trace the development of the North Wollongong foreshore through digitised council photographs, duplicate entries create false volume — inflating apparent holdings while burying unique records further down search results. Librarians and archivists describe the effect as putting noise into a signal that community historians and urban planners both rely on.

The Illawarra Regional Information Service, operated out of the Wollongong Central Library on Burelli Street, currently catalogues records across 16 member councils and organisations in the region. A report tabled to the library advisory committee in March 2026 flagged that duplicate image entries across the shared catalogue had reached a point requiring active remediation — not just ongoing monitoring. No public figure has been attached to a specific remediation cost, but comparable deduplication projects at regional councils in Victoria completed in 2024 ran to between $40,000 and $120,000 depending on collection size and vendor choice.

The decision facing the Wollongong council team is essentially three-way: pursue an in-house manual deduplication using existing library staff, contract a specialist digital asset management firm to run automated deduplication software, or adopt a hybrid model that flags probable duplicates algorithmically but leaves final deletion decisions to a trained archivist. Each path carries different risks around accidental permanent deletion of unique records — particularly for the BlueScope Steel historical photographic collection, parts of which document the Port Kembla steelworks from the 1930s onward and have no known physical backup.

The Decisions That Cannot Wait

Two deadlines are converging. The State Records NSW compliance review window opens in September 2026, giving the council roughly ten weeks to at minimum document a remediation plan. Separately, the Illawarra Regional Information Service's shared database contract with its current hosting provider expires in February 2027, and any migration to a new platform will be significantly more complex if duplicate records are carried across.

The University of Wollongong's digital humanities team, based on the Northfields Avenue campus, has flagged interest in a partnership arrangement that would provide postgraduate research labour in exchange for access to the cleaned dataset. That proposal is understood to be sitting with the council's cultural development unit but has not yet been formally accepted or rejected.

What the next eight weeks require is a written scope of works, a vendor shortlist if the hybrid or contracted model is chosen, and a heritage-risk assessment specifically covering the BlueScope and Port Kembla Harbour Trust photograph collections before any automated deletion tool is activated. The Crown Street and Keira Street commercial precincts also have photographic records held in the system that carry local heritage overlay designations under the Wollongong Local Environmental Plan 2009 — adding a planning law dimension to what might otherwise look like a simple IT cleanup.

Staff at the Burelli Street library will brief councillors at the August ordinary meeting. That session is shaping up as the practical point of no return: miss it, and the September compliance window closes without a credible plan on the record.
