Wollongong's Duplicate Image Problem: The Key Decisions Ahead

Wollongong City Council is sitting on a backlog. Across its digital asset management system, planning portals and heritage registers, thousands of duplicate image files have accumulated over more than a decade of piecemeal digitisation — creating storage costs, retrieval errors and a growing compliance headache for staff trying to process development applications in the Crown Street and Keira Street precincts.

The problem is not unique to Wollongong, but the timing makes it acute here. The Illawarra Shoalhaven Regional Development Fund has earmarked investment in local infrastructure projects through to 2028, each generating fresh tranches of photographic documentation. At the same time, BlueScope Steel's transition toward green steel production at Port Kembla means industrial-site imaging — environmental baseline photography, asset condition records, community consultation materials — is multiplying faster than legacy systems can handle.

Why the next six months matter

The practical pressure point is the State Government's planning portal upgrade, which NSW Planning has scheduled for completion by December 2026. Any council that has not resolved its duplicate image inventory before that migration risks compounding errors: wrong images attached to wrong development applications, heritage overlays illustrated with outdated or mismatched photography, and delays to approvals that Wollongong's strained housing pipeline cannot afford. The Illawarra region recorded a residential vacancy rate of roughly 1.1 per cent in early 2026, according to figures published by the Real Estate Institute of NSW, underlining how little slack exists in the local market for administrative slowdowns.

The University of Wollongong, which maintains its own significant photographic archive tied to campus development applications in the Gwynneville and Keiraville corridors, faces a parallel audit. The university's facilities division has been working with Council since late 2025 to establish a shared metadata protocol — a necessary first step before any bulk deduplication can run across either institution's holdings.

Three decisions are now unavoidable. First, Council must choose between an in-house deduplication process using its existing Civica Authority platform and a contracted external audit — a call that carries a cost differential estimated internally at between $80,000 and $220,000 depending on scope, though no formal tender has been publicly released as of this week. Second, the question of what happens to replaced images: delete, archive offline, or migrate to a read-only heritage repository hosted by Wollongong City Libraries' local studies collection on Crown Street. Third, who owns the process — IT, Planning, or a newly proposed cross-directorate working group whose terms of reference are still being drafted.

What local stakeholders are watching

The Illawarra Business Chamber has flagged the issue in correspondence to Council's planning committee, noting that delays to development application processing in the Wollongong CBD and along the Fairy Meadow to Corrimal growth corridor have real costs for members. The Port Kembla Renewable Energy Zone project, which involves multiple overlapping planning jurisdictions, is among the developments most exposed to documentation errors if duplicate or superseded images are not correctly flagged before the December portal migration.

Heritage advocates are watching a separate but related question: whether any images deleted in a bulk deduplication sweep include photographs that carry evidentiary value for heritage assessments in suburbs like Thirroul and Bulli, where older residential stock is increasingly under development pressure. The Wollongong Local Environmental Plan 2009 requires photographic evidence to support certain heritage impact assessments, meaning a poorly managed replacement process could invalidate submitted applications after the fact.

The practical timeline from here: Council's Planning and Environment Committee meets again in August, and a briefing paper on the digital asset review is expected to be tabled then. If a decision on the deduplication approach is reached at that meeting, a contracted or in-house process could begin by September, leaving a narrow but workable buffer before the December state portal cutover. Missing that window pushes the problem into 2027 — and into the middle of what promises to be a heavy development assessment period as Port Kembla and Fairy Meadow projects move from concept to consent stage.
