Central Coast Council's Digital Archive Push Hits a Snag: Duplicate Images Clogging the System This Week

Central Coast Council's ongoing effort to digitise decades of planning documents and property records struck a significant obstacle this week, when staff working on the archive project identified a backlog of duplicate image files embedded across multiple database systems. The problem, which council officers are now working to resolve, has slowed public access to development application records hosted through the council's online portal.

The timing matters. The council, which only exited formal financial administration in 2021 after a crisis that saw it accumulate more than $565 million in debt, has been under sustained pressure to modernise its internal systems and restore public confidence. Efficient, searchable digital records sit at the centre of that effort — particularly as Gosford CBD sees a wave of new development applications tied to the state government's urban renewal agenda and the long-running Gosford Revitalisation Program.

What Went Wrong and Where

The duplicate image problem appears to stem from a legacy migration that transferred scanned documents from at least two separate historical systems into a single repository. When staff at the council's Wyong offices and the Gosford administration hub both processed uploads independently — without a unified deduplication protocol in place — hundreds of property record sets ended up with multiple copies of the same site photos, survey images and building diagrams. Across the combined archive, the number of redundant files is understood to run into the thousands, though the council had not issued a formal public statement on the precise figure as of Friday.

The practical effect has been felt most sharply by small builders and private certifiers operating across suburbs like Erina, Woy Woy and Terrigal, where active development applications require fast access to historical site records. Delays in retrieving clean, verified image sets can add days to approval timeframes — a frustration for an industry already managing cost pressures and labour shortages.

Central Coast Council's DA tracker, accessible through the council website, showed more than 400 active applications lodged in the June quarter alone. Any systemic slowdown in document retrieval touches a meaningful share of those cases directly.

The Fix and What Comes Next

Council technical staff are running an automated deduplication process across the archive this week, cross-referencing file metadata and image hashes to identify and quarantine redundant entries without permanently deleting source files. That cautious approach — retain first, remove later — is standard practice in government records management, given the legal obligations councils carry under the NSW State Records Act 1998.

The work is being carried out in coordination with the council's records management team, which sits under the broader Information Services directorate. Staff at the Gosford administration building on Mann Street have been asked to flag any document retrieval failures directly to the helpdesk rather than attempting manual workarounds, to avoid compounding the backlog.

For residents and applicants, the council's planning counter at 2 Hely Street, Wyong, and the Gosford customer service centre remain open for in-person document requests during the remediation period. A council spokesperson confirmed this week that the online portal remains operational, though some image-heavy records may load with delays. Applicants with time-sensitive matters have been advised to contact the DA team directly.

The episode also adds weight to arguments being made inside council chambers for a faster rollout of a unified content management system — a project flagged in the council's 2024-25 Operational Plan but not yet fully funded. With a fresh budget cycle beginning this month, the events of this week give that line item a new urgency. Getting the digital house in order is not an abstract efficiency goal; for a council still rebuilding its reputation and its balance sheet, it is foundational work.
