Wollongong's Duplicate Image Crisis: The Key Decisions That Will Shape What Comes Next

Wollongong City Council has flagged a systemic problem with duplicate image files embedded across its planning portal, heritage registers and community communications platforms — and the decisions made in the next six months will determine how much of that mess gets cleaned up before the next local government election cycle begins.

The issue surfaced earlier this year when council staff conducting a routine audit of the Illawarra Development Application portal found hundreds of duplicate image records attached to submissions across Crown Street, Keira Street and the Northgate precinct redevelopment files. The duplicates — in some cases the same site photograph filed three or four times under different reference numbers — slow processing times, inflate digital storage costs and, in the worst cases, cause version-control errors that delay determinations.

It matters now because Wollongong is in the middle of a housing supply crunch. The state government's Transport Oriented Development reforms have pushed a wave of new medium-density applications through the Illawarra planning system since late 2024. More applications mean more image attachments, and a portal that already has a duplication problem is getting a larger workload at precisely the wrong moment.

What the Audit Revealed — and Where the Bottlenecks Are

The internal audit, tabled at a council meeting in June 2026, identified three main sources of duplication. First, applicants uploading revised plans without removing earlier versions. Second, council's own scanning workflow for legacy paper files — particularly heritage properties in Bulli, Thirroul and the West Wollongong conservation zones — which created mirror records when documents were ingested into the new Content Manager system. Third, a data migration carried out in late 2023 that pulled records from the old Pathway software without a deduplication pass.

The University of Wollongong's SMART Infrastructure Facility, which has worked with council on smart-city data projects in the past, has been informally canvassed about whether its geospatial data management expertise could assist with a remediation project. No contract has been signed, and no formal scope of work has been released publicly. The council's digital transformation budget for 2025-26 was set at $2.4 million, though it is not publicly confirmed how much of that allocation remains unspent or available for an image audit remediation project of this kind.

The Illawarra Shoalhaven Joint Organisation — which coordinates shared services across Wollongong, Shellharbour, Kiama and Shoalhaven councils — is separately reviewing whether a regional approach to document management standards could prevent the same duplication problems from compounding across all four councils' planning systems.

The Decisions Ahead — and the Timeline That Matters

Council officers have until the end of August 2026 to deliver a remediation options paper to the Environment and Planning Committee. That paper is expected to outline at least three pathways: a manual audit by existing staff, a procurement process for specialist digital asset management software, or a hybrid approach combining both.

Each option carries different cost and timeline implications. A staff-led manual audit of the estimated 4,000-plus flagged duplicate records in the Crown Street development corridor alone would take considerable internal resource. Software procurement, by contrast, requires a tender process that typically runs eight to twelve weeks under NSW Government procurement rules — meaning any new system would be unlikely to go live before mid-2027.

For applicants with projects in the pipeline — including developers with sites near the WIN Entertainment Centre precinct and landowners in the Port Kembla renewal zone — the practical advice from planning consultants operating in the region is straightforward: submit image files using consistent naming conventions referencing the DA number and revision date, and remove superseded attachments at the time of lodging updated plans. Council's planning counter at 41 Burelli Street can advise on current file format requirements.

The broader question — whether Wollongong ends up with a genuinely fit-for-purpose digital planning system or simply patches the existing one — will depend on decisions made in the next eight weeks. The August committee meeting is the first real test of whether this gets treated as a structural fix or another deferred maintenance item.
