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

Wollongong City Council's digital asset library contains thousands of images — and a growing share of them are duplicates, near-identical copies accumulated across department drives, SharePoint folders and legacy content management systems over more than a decade. The problem is not unique to Crown Street West, but the decisions about how to fix it are pressing harder than ever as the council prepares to migrate records ahead of a broader digital transformation scheduled to begin in late 2026.

The timing matters for a specific reason. The Illawarra region is mid-transition — BlueScope Steel's green steel program at Port Kembla, the renewable energy zone rezoning along the Illawarra escarpment, and a university economy anchored by the University of Wollongong's Innovation Campus on Squires Way are all generating new visual documentation at a rapid pace. Engineers, planners, communications teams and grant writers are all pulling from the same pools of photographic and graphic assets. When those pools are cluttered with duplicates, the wrong image ends up in the wrong submission — or worse, in a public-facing document where it causes confusion or reputational damage.

How Wollongong Got Here

The duplicate image problem follows a familiar pattern in mid-sized regional institutions. Each time a council department or community organisation adopted a new platform — whether a new website CMS, a social media scheduling tool or a grant portal — staff uploaded fresh copies of existing images rather than linking to a central repository. Wollongong City Council's communications and digital teams, Destination Wollongong on Burelli Street, and regional development bodies connected to the Illawarra Shoalhaven Joint Organisation have all independently built image libraries over the years with minimal cross-referencing.

The University of Wollongong faces a parallel version of the challenge. Its marketing and research communications teams manage separate asset repositories, and as the institution prepares new collateral for domestic and international recruitment campaigns in the 2027 academic cycle, duplicates create version-control risks — old branding appearing alongside new, or archived campus photography representing buildings that no longer exist in the same form after recent renovations near the McKinnon Building precinct.

Illawarra Media Group, which operates community broadcasting and digital content across the region, flagged the issue internally earlier this year after an audit found a significant share of its archived photography from the 2020–2023 period existed in at least two separate folders with no deduplication flag. The audit, described in broad terms in a regional content strategy document circulated to member organisations, recommended a unified tagging protocol be adopted before any new content management system migration begins.

The Decisions That Will Define the Fix

Three choices are sitting on the table right now, and each carries real tradeoffs.

The first is whether to use automated deduplication software or rely on human curation. Automated tools can process thousands of files in hours and flag exact or near-exact matches with high accuracy — but they struggle with context. A photograph of the Port Kembla Harbour from 2019 and one from 2024 may be near-identical in pixel terms but carry very different documentary value given the industrial changes underway at that site. Human review costs more in staff time but preserves that distinction.

The second is governance. Who owns the canonical image library going forward? If council, UOW and regional development bodies each maintain separate master libraries with no shared taxonomy, the duplicate problem will simply regenerate within two years. A shared tagging standard — even a lightweight one built on existing Dublin Core metadata conventions — would reduce that risk without requiring a single centralised platform.

The third choice is timing. Rushing the deduplication before the late-2026 digital migration risks locking in errors. Waiting until after the migration means the new system inherits the mess. Most digital records specialists recommend a staged pre-migration audit beginning no later than September 2026, with a freeze on new bulk uploads in the interim.

For Wollongong organisations watching this process, the practical step is immediate: nominate a single person in each team responsible for image sign-off before any asset is added to a shared drive or published platform. That is a low-cost intervention that costs nothing except clarity — and in a region generating as much new documentary material as the Illawarra right now, clarity is the scarce resource.
