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

Wollongong City Council is facing a growing administrative headache: thousands of duplicate site images lodged across its development application portal are undermining assessment timelines and, in some cases, pushing heritage-listed properties through the wrong approval pathways. The problem has been building for at least three years, and 2026 is shaping up as the year when a fix can no longer wait.

The issue matters right now because the Illawarra is in the middle of a development surge. Port Kembla's renewable energy precinct is attracting industrial investment, BlueScope Steel's green transition is generating a new round of environmental impact studies, and the NSW Government's housing supply push is driving a spike in residential DAs from Fairy Meadow to Shellharbour. Every one of those applications requires accurate, deduplicated photographic evidence to pass through council's system cleanly. When it doesn't, assessment officers spend time manually reconciling records instead of processing files.

Where the Bottlenecks Are Forming

The pressure is most visible at two specific points in the region. First, the Wollongong Development and Environment directorate on Burelli Street is sitting on a backlog of DAs that contain image sets flagged by the council's ePlanning software as containing repeated files — identical photos uploaded multiple times, often by applicants copying previous submissions as templates. Second, the University of Wollongong's Smart Infrastructure Facility, which provides GIS and spatial data support to several Illawarra Shoalhaven Regional Development Fund projects, has separately identified duplicate aerial imagery in shared datasets used by project managers working across the Kemblawarra industrial precinct.

Neither situation is catastrophic yet. But both point to the same underlying gap: there is no single, enforced standard for image deduplication across the multiple platforms — the NSW Planning Portal, council's internal Objective ECM system, and third-party heritage registers — that Illawarra planners are drawing from simultaneously. A heritage assessment for a property on Crown Street in the CBD, for example, might pull reference images from all three systems, with no automated check that the same photograph isn't being treated as three separate pieces of evidence.

Nationally, the problem has financial weight. The Australian Local Government Association reported in its 2025 digital services survey that councils collectively spend an estimated $47 million per year on manual data remediation tasks, with image management identified as one of the top three contributors. Wollongong, as a regional council managing more than 12,000 active property records, sits squarely in the cohort the survey flagged as high-risk for data quality degradation during high-growth periods.

The Decisions That Will Shape the Outcome

Three choices are coming to a head before the end of the 2026 calendar year. The first is whether Wollongong City Council accelerates its planned migration to an upgraded version of its spatial data platform — a project that was scoped in the 2025-26 budget but has not yet had a confirmed go-live date confirmed publicly. That upgrade would include a native deduplication layer. The second decision sits with the NSW Department of Planning, which must determine whether to mandate image integrity standards for all DA submissions lodged through the state's ePlanning portal. Without a state-level rule, individual councils will continue managing the problem inconsistently.

The third decision is more local and more immediate. The Illawarra Shoalhaven Joint Organisation, which coordinates shared services across the region's councils, is reviewing its data governance framework this quarter. If image deduplication is included as a shared-services priority — alongside the existing shared rates and asset management systems — it could fast-track a regional solution rather than leaving Wollongong to solve it alone.

For applicants lodging DAs right now, the practical advice from council's published submission guidelines is straightforward: each image file should carry a unique file name, include GPS metadata where possible, and be uploaded once to the primary documents folder only. Applicants working on Port Kembla industrial projects or University of Wollongong campus developments, which tend to involve large image sets, should audit their submissions before lodgement rather than after. A rejected or delayed DA in the current approvals climate can add weeks to a project timeline — and in an Illawarra construction market where trades are already stretched thin, weeks matter.
