Wollongong's Duplicate Image Problem: The Key Decisions That Will Shape What Comes Next

Wollongong City Council's digital asset management framework is heading toward a critical review point, with council officers expected to table recommendations to the full chamber before the end of the third quarter of 2026. At issue: a years-long accumulation of duplicate image files stored across multiple internal systems, a problem that has compounded storage costs and complicated public records compliance under the NSW State Records Act 1998.

The timing matters. Across the Illawarra, public bodies are under pressure to modernise their digital infrastructure while managing tight operating budgets. The NSW Government's broader push to consolidate agency data holdings — accelerated by the Digital Restart Fund, which has directed hundreds of millions of dollars statewide toward technology upgrades since 2019 — has put the spotlight on exactly this kind of unglamorous housekeeping. Wollongong's situation is not unique, but its scale and the competing interests involved make it one of the more consequential local decisions of the year.

Two institutions sit at the centre of the debate. The Wollongong City Gallery on Burelli Street holds a digitised collection spanning decades of regional art, and staff there have flagged that deduplication software — if applied too aggressively — risks stripping out image variants that curators regard as distinct archival records. A few blocks north, the Wollongong City Library on Kembla Street manages a separate digital repository that overlaps in places with the gallery's holdings, particularly around historical photographs of Port Kembla and the Illawarra escarpment. The question of which system is the authoritative source, and which institution controls the merge-or-delete decision, has not been resolved.

The Cost of Doing Nothing

Storage is not free. Council's 2025–26 budget documents, publicly available on the council website, show the organisation allocating funds across its information and communications technology directorate, though the specific line item for digital storage has not been itemised in publicly released budget summaries. What is known from general industry benchmarks is that duplicated files can inflate cloud storage costs by 30 to 40 per cent, according to figures published by the Australian Computer Society in its 2024 digital governance report. For a mid-sized local government with thousands of asset images — building permits, event photography, planning overlays — that is not a trivial sum.

The University of Wollongong's SMART Infrastructure Facility on Northfields Avenue has been consulted informally on the technical side of the problem, given its research focus on data systems and urban informatics. No formal contract has been announced. Separately, the Illawarra Shoalhaven Joint Organisation, which coordinates regional planning across four councils, is watching the outcome closely: its own shared digital mapping project, covering the coastline from Helensburgh to Nowra, faces a similar deduplication question as contributing councils use incompatible file-naming conventions.

What the Next Six Months Look Like

Council officers are understood to be evaluating at least three options: a full deduplication audit using automated software, a manual curatorial review led jointly by the gallery and library, or a hybrid model where automation flags candidates for human sign-off. Each carries a different cost profile and a different risk of error. The hybrid approach is regarded in digital records management circles as best practice, but it is also the most labour-intensive.

The council's ordinary meeting scheduled for late August 2026 is the most likely venue for an initial report. If councillors request further consultation — particularly from community groups with an interest in the historical photograph collections — a final decision could slip into the final quarter of the year. That would push implementation into 2027, leaving the storage cost problem unresolved for at least another budget cycle.

For residents and organisations that rely on council's digital image library — local historians, architects lodging development applications on Crown Street, media outlets covering Illawarra events — the practical advice is straightforward: download and save any council-held images you depend on before the review concludes. Once a deduplication regime is in place, files deemed redundant may not be recoverable.
