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

Wollongong City Council's digital records unit is facing a decision it can no longer defer: how to audit, deduplicate and reclassify thousands of property and infrastructure images sitting in its asset management system, with at least two competing software contracts on the table and a self-imposed deadline of December 2026 to resolve the mess.

The issue matters now because the council's broader digital infrastructure overhaul — tied to its 2025–2030 Community Strategic Plan — depends on clean, accurately tagged image data to support planning applications, heritage assessments and the maintenance scheduling of ageing assets from the Flinders Street civic precinct to the stormwater network running beneath the Gwynneville and Keiraville suburbs. Duplicate records slow assessment times and, in some cases, have caused planning officers to reference outdated photographs of sites during development reviews.

Two local institutions are already caught up in the downstream effects. The University of Wollongong's SMART Infrastructure Facility on Northfields Avenue has been in preliminary discussions with the council about whether its geospatial imaging research unit could provide technical support for a deduplication pilot. Separately, Wollongong's Crown Street Mall precinct has been flagged internally as a priority test zone, given the volume of development applications lodged for that strip over the past 18 months.

The competing options and what they cost

Council officers are weighing three broad paths. The first is a manual audit — labour-intensive, estimated to take between eight and twelve months using existing staff, and carrying a risk of inconsistent outcomes across different asset categories. The second is procurement of specialist deduplication software, with two vendors currently shortlisted; indicative pricing from comparable NSW council contracts suggests licensing and implementation costs in the range of $180,000 to $260,000. The third option is a hybrid approach: automated flagging of likely duplicates, followed by human sign-off on each deletion or reclassification.

The hybrid model has precedent in NSW local government. Shellharbour City Council completed a similar exercise across its development application image library in 2024, cutting its active image count by roughly 34 percent over six months. That figure has circulated inside Wollongong's corporate services division as a rough benchmark, though Wollongong's asset base is larger and its heritage overlay areas — including the North Wollongong foreshore and the Hill 60 precinct — add classification complexity that a straight percentage comparison does not capture.

There is also a budget question. The council's 2026–27 operational budget, adopted in June, did not include a dedicated line item for this remediation work. Any spend above the general ICT maintenance allocation would require a report to the full council, which next sits in ordinary session on 28 July.

What needs to happen before December

Three decisions are now on the critical path. First, the council's digital records team needs to complete a scoping report — originally due in May and now rescheduled — that quantifies the actual duplicate count and maps which asset categories are worst affected. Without that figure, neither the software vendors nor any potential university partner can price their involvement accurately.

Second, if the hybrid or software-only route is chosen, a procurement process under the council's standard tender rules takes a minimum of six weeks, meaning a contract would need to go out in August to leave any realistic margin before the December target.

Third, and less discussed publicly, is the question of data governance going forward. Even a clean database reverts to chaos without enforced upload protocols. Neighbouring councils that have been through similar exercises have found that the deduplication itself is the easy part — sustaining the fix requires training, consistent naming conventions and, in some cases, a dedicated records officer role that Wollongong does not currently have budgeted.

For residents and developers lodging applications through the council's online portal on Burelli Street, the practical upshot is straightforward: a resolved image database means faster assessment turnaround times and fewer requests for applicants to resubmit photographs that the system has already lost or duplicated. The council has not publicly committed to a timeline for when those improvements would be visible. The 28 July council meeting is the next concrete moment when any of that could change.
