Central Coast Council's Duplicate Image Audit: What Happens Next and the Key Decisions Ahead

Central Coast Council is facing a deadline-driven reckoning over thousands of duplicate images clogging its digital asset management system — a problem that planners say is now actively slowing approvals tied to the $800 million Gosford CBD revitalisation corridor along Mann Street and Donnison Street.

The issue surfaced formally in late June 2026 when Council's Information Services unit flagged that its property database held more than 14,000 duplicate or conflicting site images accumulated across the administration period between 2020 and 2023, when the Council was under state-appointed administrator Rik Hart. Files uploaded during that period used inconsistent naming conventions across three separate software platforms, meaning surveyors, planners and heritage officers are routinely pulling the wrong version of a site photograph when assessing development applications.

Why does this matter now? Because the State Government's Central Coast Regional Plan 2041 sets a hard target of 28,000 new dwellings across the region by 2041, and local planning panels are already processing a surge of medium-density proposals around Gosford station, Wyong town centre and the Warnervale employment precinct. An erroneous site image attached to a DA can trigger objections, delays and in the worst case a merits appeal to the Land and Environment Court — adding months and tens of thousands of dollars to projects Council is trying to fast-track.

The Competing Options on the Table

Council staff have presented three options to the elected body ahead of the August 5 ordinary meeting. The first is a manual audit conducted in-house, estimated to take eight months and requiring two temporary data officers at roughly $95,000 each. The second is a contracted remediation using AI-assisted deduplication software, quoted by one Sydney-based vendor at $340,000 for a 12-week turnaround. The third — and most controversial — is a staged freeze on new image uploads for non-urgent files while the backlog is cleared incrementally over 18 months.

The Gosford-based Central Coast Business Connect, which lobbies on behalf of about 1,200 local small businesses, circulated a briefing note to members on July 2 warning that Option 3 would bottleneck the processing of commercial tenancy fit-out approvals in the proposed Gosford Cultural Precinct around Kibble Park. Any slowdown there, the group argues, threatens the pipeline of hospitality and retail operators who have already signed heads of agreement on the precinct's ground-floor spaces.

The Heritage Office of NSW has separately written to Council noting that 43 properties on the Central Coast Heritage Register — including several terrace buildings on Baker Street, Gosford, and the Edogawa Commemorative Garden — require accurate before-and-after imagery to support conservation management plans. Without a clean dataset, Council risks breaching conditions attached to several heritage grants totalling $1.1 million administered under the NSW Heritage Near Me program.

Practical Steps and the Immediate Pressure Points

Regardless of which option Council selects on August 5, planners say two things need to happen immediately. First, a temporary verification protocol — requiring a planning officer to cross-check any site image against the physical address in NearMap before attaching it to a DA — should be implemented within a fortnight. Second, the Council's GIS team needs to produce a register of the highest-risk duplicate clusters, meaning those attached to active DAs or heritage files, so those can be manually corrected ahead of any broader remediation program.

The timing is awkward politically. Premier Chris Minns has made regional infrastructure and housing delivery a centrepiece of the government's pitch heading toward the 2027 state election, and Central Coast — as a bellwether region covering seats including Gosford and Terrigal — will be closely watched. A visible administrative failure inside Council's planning system, however technical, will be seized on by opponents already pointing to the region's troubled governance history.

For residents and developers, the August 5 meeting is the one to watch. Council's agenda papers are due for public release by July 29. Anyone with an active DA lodged through Council's e-Planning portal should check with their certifier that site photographs on file are current and correctly geo-tagged — because if the audit uncovers a mismatch on your application, the clock stops until it's resolved.
