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

Wollongong City Council is facing growing pressure to overhaul how it stores, verifies and retires duplicate imagery across its planning and heritage databases, after an audit of the council's digital asset register flagged hundreds of replicated site photographs linked to development applications lodged between 2021 and 2025. The problem, long considered a bureaucratic inconvenience, is now intersecting with major decisions about the region's built future — and the window for getting the system right is narrowing fast.

The timing matters for a specific reason. Wollongong is in the middle of one of its most consequential planning cycles in decades. The Illawarra Shoalhaven Joint Organisation is coordinating land-use assessments tied to the Port Kembla Renewable Energy Zone, BlueScope Steel's green steel transition corridor, and a raft of medium-density housing proposals stretching from Fairy Meadow to Dapto. Each of those projects depends on accurate site photography and georeferenced imagery to support environmental impact statements and heritage impact assessments. When duplicate images enter the record — sometimes under different file names, sometimes tagged to wrong parcels — planning officers cannot always tell which image is current and which is stale.

Where the Duplication Is Biting Hardest

The issue is most acute in two areas. The first is the Crown Street Mall precinct in Wollongong's CBD, where a series of mixed-use redevelopment proposals have generated overlapping photographic records that reference the same facades across multiple applications going back to 2019. Heritage NSW, which maintains a parallel register of locally significant streetscapes in that corridor, has flagged concerns — not publicly, but through correspondence reviewed by The Daily Wollongong — that image duplication is creating ambiguity about the pre-demolition condition of at least three properties currently under assessment.

The second hotspot is the Port Kembla industrial precinct itself, where Endeavour Energy's substation upgrade works and BlueScope's internal site documentation have both fed imagery into council's geographic information system since late 2023. Because the two organisations use different file-naming conventions, some images of the same infrastructure appear as distinct entries in the planning database. That may sound trivial, but it creates real risk: an assessment officer working from an apparent 2024 photograph of a specific bund wall or drainage channel could unknowingly be looking at a 2019 image under a relabelled file.

The University of Wollongong's SMART Infrastructure Facility, based on Innovation Campus off Squires Way in North Wollongong, has been in discussions with council about a geo-tagging and image deduplication pilot that would use hash-matching algorithms to identify replicated files in real time. A scoping study for that pilot was submitted to council in March 2026. No decision on funding has been announced.

The Decisions That Will Define the Next Six Months

Three choices now sit with council and its partners, and each carries a deadline. The first is whether to adopt the UOW SMART pilot or procure an off-the-shelf document management system — a decision that the council's information services division is expected to bring to the full chamber before the September 2026 ordinary meeting. Off-the-shelf platforms from vendors active in the NSW local government sector typically carry implementation costs in the range of $180,000 to $350,000, depending on data migration scope, though council has not publicly confirmed any budget allocation for this project.

The second decision is procedural: whether planning officers should be required to flag any image older than 24 months as potentially superseded when preparing assessment reports. That policy change could be enacted administratively, without a council vote, but it would require sign-off from the director of planning and environment.

The third, and broadest, question is whether Wollongong City Council will push the state government for standardised image-submission protocols across all NSW planning portals — a reform that would need to go through the Department of Planning, Housing and Infrastructure in Parramatta. Several Illawarra councils raised the issue at a Regional Planning Managers forum held in Wollongong in May 2026, but no formal submission has yet been lodged.

For residents watching development applications move through the system — whether near Keira Street, along Corrimal's main strip, or in the rapidly changing areas around Dapto station — the practical upshot is straightforward. Until the image problem is resolved, there is a non-trivial chance that a planning decision affecting their street rests partly on a photograph that no longer reflects what is actually there.
