Council's Duplicate Image Mess: What Happens Next and the Key Decisions Ahead

Central Coast Council is confronting a concrete administrative reckoning. Its digital asset library — used across planning, communications, infrastructure and community services — contains a substantial volume of duplicate image files that have compounded errors in public documents, slowed internal workflows and, in at least some cases, caused the wrong versions of site photographs to appear in development application materials lodged through the NSW Planning Portal.

The problem matters now because the council is simultaneously managing some of the most consequential decisions in its recent history. The Gosford CBD renewal corridor, flood resilience planning across the Wyong River catchment, and a housing strategy designed to absorb Sydney overspill are all document-heavy programs that depend on accurate, version-controlled visual records. Getting the image library wrong at this stage is not a clerical nuisance — it is a governance risk.

Where the Problem Sits

The duplicate image issue is concentrated in the council's internal content management system, which was restructured following the administration period that ended when elected councillors were restored to office in December 2022. That administration, which ran from October 2020, left behind fragmented digital infrastructure across several departments. Staff who spoke generally about the situation — without being named, given they are not authorised to discuss internal IT matters publicly — indicated the library covers assets used by the planning directorate, the communications team and the Gosford Revitalisation project office, all of which operate from the Mann Street administrative hub.

The Gosford Revitalisation project, which encompasses the precinct bounded by Donnison Street to the north and Georgiana Terrace to the east, relies on georeferenced site photography to support heritage assessments and DA referrals. Duplicate or mismatched images in that context carry real consequences: a heritage adviser reviewing a streetscape on Baker Street in Gosford needs to know whether the photograph they are looking at reflects current conditions or a file from two years prior.

At the Wyong end of the council area, flood resilience planning under the NSW Government's Resilient Lands Program uses aerial and ground-level imagery to document drainage infrastructure and identify at-risk parcels. Duplicate file naming in that dataset creates the possibility — not yet confirmed as having caused a formal error — that outdated pre-flood imagery could be cross-referenced against current drainage assessments.

The Decision Points Coming Up

Three choices will define how quickly this gets resolved. First, the council must decide by the end of the current financial year — 30 June 2026 has already passed, making the next budget cycle the operative window — whether to fund a dedicated digital asset audit or absorb the work into existing IT staff capacity. The difference in resourcing is not trivial: specialist digital asset management contractors working on comparable local government projects in NSW have quoted in the range of $80,000 to $150,000 for a full deduplication and taxonomy rebuild, depending on library size.

Second, the council needs to determine which system becomes the authoritative source of record. At present, the planning directorate and the communications team are understood to maintain parallel but not fully synchronised libraries. Consolidation requires a policy decision, not just a technical one, and that decision needs councillor sign-off given its implications for how DA-related documents are stored and retrieved under the Government Information (Public Access) Act 2009.

Third — and most practically pressing — is the question of what happens to development applications already lodged that contain images now flagged as potentially duplicated or incorrectly versioned. Council planners will need a clear internal protocol for reviewing those files before assessments are finalised, particularly for any DA within the Gosford Heritage Conservation Area or along the Tuggerah to Wyong employment corridor.

The council's next ordinary meeting is scheduled for late July. If a formal report on the digital asset review does not appear on that agenda, residents and applicants with active DAs in the Gosford and Wyong precincts would be reasonable to ask why — and what the timeline for resolution actually is.
