Wollongong's Digital Image Problem: The Numbers Behind a City Council Data Headache

Wollongong City Council is sitting on more than 47,000 digital image files across its public-facing web infrastructure, and an internal review completed last month found that roughly 34 percent of them are duplicates — redundant copies of the same photographs stored across multiple content management systems simultaneously. The audit, conducted by council's Digital Services unit between April and June 2026, has triggered a broader conversation about data governance costs in a region that has spent heavily on digital transformation over the past three years.

The timing matters. NSW councils are under mounting pressure from the state government's Local Government Act review to demonstrate value-for-money in technology spending. Wollongong, which serves a population of approximately 225,000 residents across suburbs from Helensburgh in the north to Shellharbour's boundary in the south, spent $2.3 million on digital infrastructure upgrades in the 2024–25 financial year alone. Duplicate image data is not a trivial footnote in that ledger — redundant storage costs money every month, and degraded search results on council platforms erode public trust in civic information.

The council's main corporate website, the Wollongong Art Gallery's digital collection portal on Keira Street, and the library network's catalogue system based at the Central Library on Burelli Street were all flagged in the review. The Art Gallery portal alone contained 6,200 image records, of which technical staff identified 1,840 as duplicates — nearly 30 percent of the collection's online presence. The library system showed a worse ratio: 41 percent of its 9,500 digitised local-history photographs were stored at least twice, in some cases appearing in three separate database tables after a 2023 migration to a new content platform went only partially completed.

What the Numbers Actually Cost

Storage is cheap until it isn't. Council's Azure cloud hosting contract, renewed in March 2025 for a 24-month term, prices data storage at approximately $0.023 per gigabyte per month. Duplicate image files across all council systems account for an estimated 1.4 terabytes of redundant data. That works out to around $32 a month in direct cloud costs — a figure that sounds trivial until you add the labour overhead of staff manually sifting through misfiled records, broken metadata tags and mis-attributed photographs when responding to public information requests under the Government Information (Public Access) Act. Council's Digital Services team logged 214 staff-hours between January and March 2026 dealing specifically with image identification errors generated by the duplication problem. At an average classified salary of $48 per hour for APS-equivalent council technical staff, that quarter alone cost ratepayers roughly $10,270 in wasted time.

The duplication issue is also distorting planning and heritage records. Several photographs of the Port Kembla steelworks precinct — now central to BlueScope Steel's green steel transition documentation and the state government's Port Kembla Renewable Energy Zone planning overlays — appear under conflicting file names and metadata dates across council's heritage register. Planners working on the Illawarra Shoalhaven Regional Development Fund submissions have had to cross-reference physical archives at the Wollongong City Library to verify image provenance before including them in formal documents.

What Happens Next

Council's Digital Services team has recommended a phased deduplication program running from August 2026 through February 2027, using open-source tooling alongside a contracted review by a Sydney-based data management firm. The projected cost is $87,000 — a figure that will go before the Environment and Planning Committee at its scheduled August 12 meeting. If approved, the project will establish a single Digital Asset Management system, centralising all council image libraries under one taxonomy aligned with the NSW Government's Digital Information Security Policy.

For residents, the practical upshot is straightforward. Search results on the council website for local history images, development application photographs and event galleries should become more accurate and faster to load. The Wollongong Art Gallery's public collection search — accessible free of charge to anyone with a library card — is slated as the first system to go live under the new platform, targeted for November 2026. Anyone who has submitted photographs to council's heritage register in the past five years may receive a notification asking them to verify metadata, particularly for images related to properties in the Crown Street Mall precinct or the West Wollongong heritage corridor.
