The Numbers Don't Lie: Central Coast Councils Lost Thousands of Hours to Duplicate Digital Records

Central Coast Council's digital asset library contains an estimated 40,000 image files, but internal audits conducted as part of the council's ongoing ICT remediation program have flagged that a significant proportion — believed to be in the range of 15 to 20 percent — are near-identical duplicates consuming server storage and slowing down document workflows across departments. That figure, drawn from the council's broader digital housekeeping work since it exited administration in 2021, has quietly become one of the more telling indicators of how deeply disorganised the organisation's data infrastructure had become.

The timing matters. Central Coast Council is mid-way through a multi-year financial recovery, and every dollar and work-hour counts. Gosford's CBD renewal program, centred on Mann Street and the planned activation of the former Gosford Waterfront site, depends on planning and communications teams being able to pull accurate, current visual assets quickly. When staff wade through layers of duplicate photographs — some dating back to the early 2010s — to find a single usable image of, say, the Gosford Regional Gallery or the Kibble Park precinct, the cumulative cost in staff time adds up faster than it looks on any single line item.

What the Data Actually Shows

Duplicate image files are not a trivial housekeeping issue. Research published by technology governance body AIIM found that organisations managing unstructured digital content — which includes photos, PDFs and scanned documents — spend an average of 2.5 hours per employee per week searching for files that either cannot be located or turn out to be the wrong version. For a council the size of Central Coast, which employs roughly 1,500 staff across its Gosford and Wyong administration hubs, that translates to a substantial productivity drain across a full financial year.

Storage costs compound the problem. Enterprise-grade cloud storage through platforms used by NSW local government typically runs between $80 and $150 per terabyte per month, depending on redundancy and backup configurations. A library bloated with duplicates doesn't just waste money — it degrades search functionality, increases the risk that outdated imagery (including images of sites now demolished or significantly altered along the Peninsulas or in Toukley) gets used in public-facing communications, and undermines the reliability of the council's records management obligations under the State Records Act 1998.

The problem sharpened after 2020, when the council collapsed into administration under the NSW Government, triggering a forensic review of finances and governance. Digital asset management was not the headline crisis — that was a reported $565 million debt — but the audit processes that followed exposed how little standardisation existed across the merged entity, which had absorbed the former Gosford City Council and Wyong Shire Council in the 2016 amalgamation. Two councils, two separate IT systems, two separate image libraries, a decade of accumulated content — and no deduplication protocol applied at the point of merger.

The Fix, and What It Will Take

Automated deduplication software — tools that identify and flag near-identical files using perceptual hashing algorithms — can now process a 40,000-file library in under four hours, flagging potential duplicates for human review rather than mass-deleting. Pricing for mid-tier platforms suited to local government sits between $3,000 and $12,000 annually, depending on user licences and storage volume. That's a fraction of the staff hours being lost each year.

Central Coast Council's ICT team, operating out of the Baker Street administration centre in Gosford, has been working through a staged technology modernisation plan since the 2021 exit from administration. Whether a dedicated digital asset management solution sits formally on that roadmap is something the council has not publicly confirmed. Residents and ratepayers with an interest in how council communications are managed — including anyone tracking the Gosford CBD renewal or the proposed Warnervale Town Centre development — can submit questions through the council's public interest disclosure and information access channels.

For now, the numbers suggest the council is carrying a fixable inefficiency that costs more to ignore than to resolve. In an organisation still climbing out of one of NSW local government's worst financial collapses, that's a number worth paying attention to.
