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

Wollongong City Council's planning portal is carrying hundreds of duplicate property images — some dating back to 2019 — that are complicating development applications and misleading prospective buyers at a time when the housing market can least afford the confusion. The problem sits quietly inside the system, but its consequences land hard on the ground.

The timing is awkward. Across the Illawarra, the pressure to unlock new housing supply has intensified through 2026, driven by state government housing targets attached to Wollongong's local environmental plan and the broader NSW Housing Accord. When a development application lands at the council's Burelli Street offices with imagery referencing a building already demolished or a site already rezoned, delays follow. Those delays cost money and, ultimately, slow the delivery of homes the region badly needs.

Where the Problem Is Showing Up

The issue is not confined to the council portal. Real estate listing platforms drawing on the same underlying land title and valuation databases have begun surfacing duplicate or mismatched images against addresses in suburbs from Fairy Meadow to Dapto. Properties listed on the Crown Street commercial strip and in the Northfields Avenue estate in Keiraville have both appeared in local industry discussions as examples where image records failed to reflect the current state of the site.

The University of Wollongong's smart infrastructure research group has been working on automated image deduplication tools applicable to local government datasets, though that work remains at the research stage. In the meantime, the practical burden falls on council planning officers and, more often than not, on applicants themselves, who must manually supply updated site photography to override incorrect records held in the state's planning portal, the NSW Planning Portal administered from Parramatta.

BlueScope Steel's ongoing industrial transition at Port Kembla has added another layer of complexity. The Port Kembla precinct is one of the most rapidly changing industrial landscapes in regional NSW right now. Buildings are being decommissioned, new infrastructure is being staged, and the footprint of the site is shifting year by year. Aerial and street-level imagery tied to Port Kembla addresses can become outdated within a single planning cycle — sometimes within 12 months of capture — creating a specific and recurring headache for developers working on the adjacent renewable energy zone.

The Decisions That Will Shape What Comes Next

Three decisions are now in front of the organisations that matter most here. First, Wollongong City Council will need to determine whether it manually audits its image library or waits for the NSW Department of Planning to push a system-wide refresh through the state portal. A manual audit of the council's estimated 4,200-plus active development files would be a significant resource commitment, but the alternative — leaving stale images in the system — carries its own cost in officer time spent fielding queries.

Second, the Illawarra Shoalhaven Joint Organisation, which coordinates planning policy across the region's four councils, has an opportunity to raise the imagery standards issue as a standing item at its next quarterly meeting. Standardising image submission requirements across Wollongong, Shellharbour, Kiama and Shoalhaven councils would reduce inconsistency and give developers a cleaner run through multi-council projects, particularly in growth corridors near the Albion Park Rail bypass route.

Third, the state government's own timetable matters. The NSW Planning Portal underwent a partial update in March 2026, but image deduplication was not part of that release. Any further system work is now unlikely before the fourth quarter of 2026, according to the portal's published roadmap — meaning the gap between the physical reality of a fast-changing city and its digital representation will persist for at least another six months.

For anyone lodging a development application in Wollongong before December, the practical advice is straightforward: do not assume the imagery already on file is current. Commission fresh site photography, include a date-stamped site plan, and attach both to the application at lodgement. That adds upfront cost — typically between $300 and $800 for a standard residential site — but it is considerably cheaper than a request for information notice that stalls approval by four to six weeks.
