How Wollongong's Council Website Ended Up With Hundreds of Duplicate Images — And What's Being Done About It

Wollongong City Council's digital content library contains several hundred duplicate image files, a legacy of at least three separate website platform migrations stretching back to the early 2010s. The council has confirmed a structured review of its digital asset management system is underway, with the bulk of remediation work targeting the Crown Street civic precinct's public-facing web properties and the Illawarra Performing Arts Centre's event archive pages.

The issue matters now because the council is mid-way through a broader digital transformation program tied to its 2025–2030 Community Strategic Plan. Duplicate image files don't just consume server storage — they create indexing conflicts that degrade search engine performance, slow page-load times for residents trying to access planning documents or event listings, and complicate accessibility compliance under the NSW Government's digital inclusion standards.

How the Duplication Built Up Over a Decade

The problem has roots in a familiar story for mid-sized local governments. When the council migrated from its legacy content management system to a new platform around 2014, bulk image uploads were carried across without deduplication checks. A second migration, completed around 2019, repeated the pattern. Staff working under deadline pressure during events like the 2020 bushfire emergency information rollout and the subsequent COVID-19 public health pages uploaded images directly without cross-referencing the existing library. By the time internal auditors flagged the issue in late 2024, certain stock photography assets — aerial shots of Port Kembla Harbour and beach images from Flagstaff Hill — appeared in the library more than a dozen times each under slightly different file names.

The University of Wollongong's Digital Futures research group, which has previously consulted on civic technology projects in the Illawarra Shoalhaven region, notes that duplicate asset accumulation is among the three most common technical debts local councils carry into modern digital platforms. The problem is compounded when organisations rely on volunteer contributors or rotating casual staff, as council communications teams often do around major local events held at WIN Entertainment Centre or Stuart Park.

What the Cleanup Involves — and What Comes Next

Wollongong City Council's digital team is working through a phased replacement process rather than a single bulk deletion. In the first phase, automated scripts identify files with identical pixel dimensions, file sizes and metadata creation dates. In the second phase, human review confirms which version carries the correct licensing and accessibility alt-text before the duplicates are archived rather than permanently deleted — a precaution that preserves records in case of freedom of information requests.

The Illawarra Shoalhaven Regional Development Fund has allocated a modest portion of its digital capacity-building stream toward helping smaller partner organisations — including Destination Wollongong and the Wollongong Art Gallery on Kembla Street — audit their own web image libraries, which feed into regional tourism platforms. Those secondary audits are expected to conclude by the end of the third quarter of 2026.

For residents and community organisations that upload images directly to council consultation portals — such as the feedback platforms used for the Fairy Meadow urban renewal corridor and the Port Kembla Green Steel precinct planning process — the practical advice is straightforward. Use the lowest acceptable resolution that still meets the platform's display requirements, name files descriptively and consistently before uploading, and avoid re-uploading the same image if a submission is revised. Those three habits alone would have prevented a significant share of the duplication that now requires remediation. The council's digital team has published a one-page upload guide on the council website, under the Get Involved section, as of June 2026.
