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

Wollongong City Council is at a crossroads over how to handle a growing backlog of duplicate images and digital records embedded in its planning portal and property information systems — a technical problem that has quietly ballooned into a governance question with real consequences for development applications, heritage listings and public transparency.

The issue surfaced during a broader digital infrastructure review commissioned in early 2026, when council's information technology team identified thousands of duplicated image files attached to development applications lodged through the NSW Planning Portal. Some files had been uploaded as many as four times against a single DA record, consuming server storage and, more critically, creating confusion about which document version is authoritative.

Why This Matters for Wollongong Right Now

The timing is not incidental. Council is mid-way through processing a surge of development applications tied to the Illawarra Shoalhaven Regional Development Fund and the expanding Port Kembla Renewable Energy Zone precinct along Foreshore Road. Both programs are generating complex, multi-stage applications where accurate document trails matter legally. A duplicated or mislabelled image attached to a heritage impact statement or site plan can delay approval, trigger objection periods and, in the worst case, expose council to legal challenge.

Wollongong's Crown Street development corridor and the Lysaghts precinct in Port Kembla — both undergoing rezoning pressure linked to BlueScope Steel's green transition — are among the areas where DA documentation errors have caused the most administrative friction this financial year, according to council's published agenda papers for its June 30 ordinary meeting.

The University of Wollongong's Smart Infrastructure Facility on Northfields Avenue has been in informal discussions with council about whether its digital twin research could be applied to the document audit problem, though no formal agreement is in place.

What the Data Shows — and What Council Must Decide

Council's June agenda papers noted that the duplication problem affected records going back to at least July 2021, when the current iteration of the NSW Planning Portal was rolled out across local government areas. Remediation quotes from two external digital records management firms ranged from $180,000 to $340,000 for a full audit and clean-up, depending on whether the scope included archival digitisation of pre-2015 paper files held at the council depot on Bourke Street, Fairy Meadow.

Three options are now on the table. The first is a full external audit contracted to a specialist firm, which would deliver clean records by mid-2027 but carries the higher price tag. The second is an internal remediation using existing IT staff, cheaper but slower, with a projected completion date of late 2028 — meaning the backlog grows during Port Kembla's busiest development window. The third option, still being scoped, would use automated deduplication software applied across the system in a single pass, which carries a risk of incorrectly flagging unique documents as duplicates.

Council's Development and Environment Committee is scheduled to receive a detailed briefing in August 2026, with a recommendation expected at the September ordinary meeting. Whatever path is chosen will need to align with the NSW Government's Digital Information Security Policy, updated in January 2026, which sets mandatory standards for local government record integrity.

For residents and developers tracking applications in suburbs like Figtree, Warrawong and the North Wollongong waterfront precinct, the practical advice is straightforward: if you have a live DA lodged through the NSW Planning Portal, check that your uploaded images and plans are correctly labelled and have not been duplicated in the supporting documents tab. Council's development information team at the Burelli Street customer service centre can confirm what is on the system record. Getting ahead of any discrepancy now is far simpler than contesting it after a decision notice has been issued.

The September vote will set the tempo for Wollongong's digital planning infrastructure for the rest of the decade. With the Port Kembla energy precinct alone expected to generate hundreds of new DAs before 2030, getting the document system right is not a minor housekeeping task — it is foundational to how the city manages its biggest economic shift in a generation.
