The Numbers Behind Central Coast Council's Image Duplication Problem

Central Coast Council is sitting on a digital asset library bloated with thousands of duplicate images, a problem that a recent internal content audit quantified for the first time and that council staff say has quietly drained administrative capacity for years. The audit, completed ahead of the council's mid-2026 website redevelopment milestone, found that roughly 34 percent of image files stored across council's content management systems were redundant copies — the same photograph or graphic saved under different file names, in different folders, or uploaded multiple times across separate departmental microsites.

The timing matters. Council is currently mid-way through a broader digital transformation tied to its post-administration recovery plan, and the Gosford CBD renewal project — centred on Mann Street and the waterfront precinct — is generating a steady pipeline of new promotional and planning imagery. Cleaning up the existing archive before new material floods in is now a practical deadline, not a theoretical one.

What the Numbers Actually Show

The audit examined assets held across three separate platforms: the primary council website, the Your Central Coast engagement portal used for community consultation, and a legacy microsite still hosting content from the former Wyong Shire Council, which merged with Gosford City Council in May 2016. Across those three repositories, auditors identified more than 11,400 stored image files. Of those, approximately 3,900 were flagged as duplicates or near-duplicates — images differing only in resolution, compression level, or file format but depicting identical content.

Storage cost alone is a minor concern; cloud hosting at council's scale runs to a few hundred dollars a month regardless. The real cost is in staff time. When a communications officer at the Gosford-based council headquarters needs to locate an approved image of, say, Tuggerah Lake or the Kariong interchange for a media release, they may encounter a dozen near-identical versions with no clear record of which has been formally approved for public use, which carries the correct licence, and which is simply a working draft someone uploaded and forgot. Each disambiguation decision takes minutes. Multiplied across dozens of staff and hundreds of publications per year, the cumulative drag is measurable.

Council's digital team estimated the audit itself — a manual plus automated review process — consumed approximately 140 staff hours over six weeks between April and May 2026. The automated deduplication tool licenced for the project cost around $4,200 for a six-month subscription. Those figures haven't been independently verified by this masthead, but they were included in a council briefing note tabled at the May ordinary meeting and are drawn from publicly available meeting minutes.

The Fix, and What Comes Next

The proposed solution has two stages. First, a culling exercise: council's digital team, operating out of the Gosford administration building on Hely Street, will work through the 3,900 flagged files and reduce them to canonical single copies, each tagged with provenance, licence status, and approved-use categories. The target completion date is September 30, 2026 — timed to precede the relaunch of the main council website currently scheduled for the fourth quarter of this year.

Second, a governance layer. Going forward, image uploads to the council CMS will require a mandatory metadata field confirming copyright clearance. Staff from the Wyong Lakes and Terrigal-area offices, who currently operate with considerable autonomy over their local pages, will be folded into a centralised upload workflow. That change alone is expected to reduce new duplicate creation by around 60 percent, according to the briefing note.

For ratepayers, the practical upshot is a council communications operation that should run faster and make fewer errors about image licensing — a problem that has caught other NSW councils in copyright disputes in recent years. The Central Coast's redevelopment ambitions, from the Gosford waterfront to the proposed Wyong Town Centre upgrade, will generate significant visual documentation. Getting the filing system right before that volume arrives is the kind of unglamorous infrastructure work that rarely makes headlines but determines whether the more visible projects are communicated clearly or dissolve into digital clutter.

The September deadline is firm, according to the meeting minutes. Whether the culling is finished on schedule will be visible in the council's next quarterly performance report, due in October.
