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

Wollongong City Council is facing a fork in the road over how it handles thousands of duplicate and mislabelled digital images lodged across its planning, heritage and community records systems — a problem that has quietly compounded since the council migrated to a new document management platform in late 2024.

The timing matters. The Illawarra is in the middle of an infrastructure and development surge. Port Kembla's renewable energy zone is drawing new investment proposals. BlueScope Steel's green transition is generating fresh environmental impact documentation. Development applications in suburbs from Fairy Meadow to Dapto are up, and every one of them depends on accurate, retrievable image records. When duplicate files clog those systems, assessment timelines blow out and staff spend hours on manual reconciliation rather than processing new applications.

Where the Problem Sits

The duplication issue is concentrated in two key areas: the council's Development Application tracking portal, which residents access via the Crown Street civic precinct offices, and the Wollongong Heritage Office's digital archive, which holds photographic records for more than 600 heritage-listed properties across the local government area. In both systems, images uploaded by applicants or council officers have in some cases been stored multiple times under different file names, creating records that are technically identical but catalogued separately.

The University of Wollongong's SMART Infrastructure Facility on Northfields Avenue has previously partnered with council on data-management pilots, and sources familiar with those arrangements say the facility's expertise in spatial data and digital twinning is directly relevant to the kind of automated deduplication tools that could resolve the backlog without requiring full manual review. No formal engagement has been announced for this specific project.

Illawarra Shoalhaven Joint Organisation, which coordinates regional planning across four councils including Wollongong, Shellharbour, Kiama and Shoalhaven, flagged data integrity as a shared risk in its 2025-26 regional priorities document. Duplicate imaging in council systems was listed as a category of concern alongside cybersecurity and records accessibility.

The Decisions That Now Define the Outcome

Three choices sit on the table, and council officers are expected to bring a formal recommendation to the August 2026 ordinary meeting.

The first option is a manual audit — methodical but slow. Based on comparable local government deduplication projects in the Hunter and Central Coast regions, a full manual review of a system holding roughly 80,000 image files typically takes between six and nine months and costs between $120,000 and $180,000 in staff time and contractor fees, according to published tender records from those councils.

The second option is automated deduplication software, which can process large libraries in days rather than months. The catch is integration. Council's current document management system, implemented under a 2024 contract, uses a proprietary file structure that not all off-the-shelf tools can read without custom middleware. That adds cost and a procurement step.

The third option — and the one gaining traction in some internal discussions — is a hybrid approach: run automated tools over the heritage and DA archives separately, then assign a small team to manually verify flagged matches before deletion. This limits the risk of permanently removing a genuinely distinct image that happened to share a file name.

The August council meeting will also need to resolve who owns the outcome. Responsibility currently sits across at least three internal teams: the Planning and Environment directorate, the Information Management unit, and the Heritage Advisory Committee, which meets quarterly at the Wollongong City Gallery on Burelli Street. Clearer governance is widely seen as a prerequisite for any technical fix holding long-term.

For residents and developers lodging applications right now, the practical advice is straightforward: name image files specifically before uploading — include the street address, date and a brief descriptor — and keep local copies of everything submitted. Council's DA tracker allows applicants to view lodged documents, and cross-checking that what appears in the portal matches what was submitted can catch duplication errors early, before they delay an assessment. The Crown Street planning counter can assist with urgent file queries in person on weekday business hours.
