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

Wollongong City Council's digital asset library contains thousands of duplicate images — some files appearing as many as four or five times across different internal systems — and the organisation is now under pressure to decide how it handles the cleanup before a planned migration to a new content management platform scheduled for the first quarter of 2027.

The issue is not unique to the council. It has surfaced simultaneously across several major Illawarra institutions, exposing a shared failure to establish consistent digital governance during the rapid shift to remote working after 2020. The timing matters because several of those organisations are mid-way through significant transformation programs that depend on clean, searchable records.

At the University of Wollongong's Innovation Campus on Squires Way, staff working on research communications flagged the problem internally after discovering that the same aerial photography of the Illawarra escarpment had been stored under at least three different file names across two separate cloud drives. At Port Kembla, BlueScope Steel's corporate communications team — which documents the steelworks' ongoing green steel transition for investor reporting — is understood to be conducting its own audit of photographic assets ahead of a major ESG report due later this year. Neither organisation has publicly confirmed the scale of their respective reviews.

Why the Stakes Are Higher Than They Look

Duplicate images are rarely just a tidiness problem. When a council planner in Crown Street's development assessment office pulls the wrong version of a site photo — one that predates a demolition or a flood event — it can introduce errors into a planning submission that has legal consequences. The same risk applies to infrastructure records. Wollongong's upgraded stormwater network around Flagstaff Hill Road, completed in stages between 2023 and 2025, generated hundreds of before-and-after site photographs. If those images are duplicated or mislabelled, the maintenance record becomes unreliable.

The broader context is the Illawarra Shoalhaven Regional Development Fund, which channels state and federal money into projects across the region and requires grant recipients to maintain auditable project documentation, including photographic evidence of milestones. Organisations that cannot produce clean, date-stamped image records risk complications during acquittal processes. The fund's documentation requirements were tightened under guidelines updated in late 2024.

Digital archivists estimate — though the figure varies by sector — that duplicate files can account for between 20 and 40 percent of total storage in organisations that have never run a formal deduplication process. Cloud storage is cheap enough that most teams simply never bothered to audit.

The Decisions That Cannot Be Deferred

Three choices are now urgent for any Wollongong institution sitting on an unaudited image library. First: who owns the problem? Duplicate images accumulate precisely because no single person or team has clear responsibility for the asset library. Appointing a named digital asset manager — not a committee, a person — is the foundational step that most organisations skip.

Second: which version survives? Automated deduplication tools can identify identical files, but they cannot judge which copy of a near-identical image is the correct one. A photograph taken the morning before a storm looks almost the same as one taken the afternoon after it, but the difference matters. Human review of flagged duplicates is non-negotiable for any record with legal, planning or financial significance.

Third: what is the retention policy going forward? Wollongong City Council's current records management framework, like those of most NSW local councils, follows the State Records Act 1998 and associated retention and disposal authorities. Digital images tied to development applications must be kept for specific periods depending on the application type — some indefinitely. Any deduplication process that accidentally deletes a record within its mandatory retention window creates a compliance breach.

The council's planned 2027 platform migration is the practical deadline. A system migration that imports duplicate-laden data simply moves the problem into a newer, more expensive environment. Organisations that want to avoid that outcome have roughly six months to act — starting now, in July 2026, with an audit scope, a named owner, and a written decision framework before a single file gets deleted.
