Wollongong Museums Battle Digital Image Duplicates

Wollongong's cultural and public institutions are facing mounting pressure to address a quiet but costly problem: thousands of duplicate and mismatched digital images embedded across council websites, heritage archives and research databases, with no consistent regional standard for how they should be identified or replaced.

The issue has surfaced publicly in recent weeks as the Wollongong City Council undertook a mid-year audit of its online planning and development portal — a system used daily by builders, residents and businesses lodging applications through the Illawarra Shoalhaven Joint Organisation's shared digital infrastructure. Staff discovered that image files attached to multiple heritage-listed property records on Burelli Street and in the Gwynneville precinct had been duplicated across dozens of entries, with some photographs misattributed to the wrong addresses entirely.

Why This Matters for Wollongong Right Now

The timing is not incidental. Wollongong is midway through a significant expansion of its digital public record systems, driven partly by a 2024 commitment under the NSW Government's regional digitalisation funding round. That program, administered through Service NSW, allocated resources for councils across the Illawarra Shoalhaven region to migrate legacy records into standardised cloud platforms by mid-2027. Getting duplicate image data wrong now means compounding errors across a system that will underpin planning decisions, heritage assessments and infrastructure approvals for years.

The University of Wollongong's Faculty of Engineering and Information Sciences has been tracking the broader challenge. Researchers there have been working on automated duplicate-detection tools developed in part through the SMART Infrastructure Facility on Squires Way, which has existing partnerships with local government on data integrity projects. The core technical argument those researchers make — without yet publishing formal findings — is that replacement of duplicate images is not simply a storage problem. It is a data provenance problem: once an incorrect image enters a public record, every downstream document that references it inherits the error.

Illawarra Local Aboriginal Land Council, which maintains its own digital archive of culturally significant site photographs across the region, has also flagged concerns. The organisation has been in discussions with the council's heritage team about establishing a shared verification protocol before the mid-2027 deadline — a step that heritage practitioners say would be the most practical safeguard against the problem recurring.

What the Broader Expert Conversation Looks Like

Outside Wollongong, the debate about duplicate image replacement has been running at a national level through the Australian Society of Archivists, which held a dedicated session on the subject at its November 2025 conference in Adelaide. Practitioners there broadly agreed that institutions needed written replacement policies — not just technical processes — specifying who has authority to delete an original file, what metadata must be preserved, and how the replacement is logged for future audits.

That guidance is directly relevant here. Wollongong City Library's Local Studies collection, housed at the Crown Street building in the CBD, holds digitised photographs dating to the 1880s covering Port Kembla, Figtree and the northern suburbs. A librarian familiar with the collection confirmed in a public forum last month that some image records in that archive carry duplicate file identifiers — an artefact of a 2019 scanning project — though the library has not yet publicly detailed a remediation timeline.

For residents and businesses dealing with council systems in the meantime, the practical advice from digital records practitioners is specific: if you receive a planning or heritage document that includes a photograph you believe is incorrectly matched to your property, lodge a written correction request through the council's Development Services counter on Burelli Street rather than flagging it through the online portal alone. Paper-trail corrections are easier to audit and less likely to create further duplication. The council's development portal carries a formal review mechanism under the Environmental Planning and Assessment Act 1979, and a written submission triggers a statutory obligation to respond within 28 days.

The broader resolution — a Wollongong-specific duplicate image replacement policy with clear authority and audit trails — is likely to be recommended as part of the regional digital audit's final report, expected before the end of 2026.
