How Central Coast Council's Property Records Ended Up Full of Duplicate Images — and Why It's Taken Years to Fix

Central Coast Council is working through a systematic audit of its digital property records after years of duplicate images — some properties carrying dozens of near-identical photographs filed under multiple reference numbers — created compounding errors in planning assessments, heritage registers and flood-mapping overlays. The problem is not new. But the scale of it, now being quantified through a records-management review that began in late 2025, is larger than council administrators had previously acknowledged.

The timing matters. The region is in the middle of a renewed push on Gosford CBD renewal, with several development applications lodged along Mann Street and the Gosford waterfront precinct requiring accurate site documentation as a precondition of assessment. Duplicate or misattributed imagery can trigger delays or, worse, decisions based on the wrong site data. With the state government watching the council's administrative performance closely following the 2020-2022 administration period, any process failure carries political as well as practical weight.

How the Problem Accumulated

The roots go back to at least 2016, when the former Gosford City Council and Wyong Shire Council merged to form Central Coast Council. The amalgamation folded two separate digital asset management systems into one, and the migration was not clean. Images tagged to properties in the old Gosford system were in some cases re-ingested when Wyong records were uploaded, generating duplicates at the database level. Staff working under the merged council's early administrative structure had neither the time nor the specific mandate to reconcile them.

The 2020 financial crisis that sent the council into administration under state-appointed administrator Rik Hart added another layer. Between October 2020 and May 2022, the council's focus was on solvency — rates revenue, cost-cutting, restructuring debt that had reached roughly $565 million by the time the crisis peaked. Records hygiene was not a priority. Some positions in the council's information management team were left vacant or consolidated. The backlog grew.

By the time elected councillors returned in December 2021, the digital property library held a substantial volume of unverified imagery. Properties along The Entrance Road, around Gosford's railway station precinct and in suburbs including Woy Woy and Tuggerah were among those flagged in internal reviews as having the highest rates of duplicate or conflicting image records, according to the council's own asset management documentation released under a Government Information Public Access request earlier this year.

What the Audit Is Doing Now

The current records review, run through council's City Futures directorate, is working precinct by precinct. The Gosford CBD has been prioritised, partly because of the volume of active development applications and partly because the imagery there intersects with heritage listings — including properties on Donnison Street and parts of the historic commercial strip near Kibble Park — where accuracy has legal weight.

The process involves cross-referencing images against cadastral data, date-stamping metadata and, where necessary, commissioning fresh site photography. Council has engaged a records management contractor to assist, though the council has not publicly confirmed the contract value. The audit is expected to take until at least the third quarter of 2026 to cover the priority precincts.

This comes as Sydney recorded its hottest June since 1859, a result that climate researchers say reflects a step-change in baseline conditions. On the Central Coast, that context is directly relevant: flood-mapping and climate resilience planning both depend on accurate, current site imagery to model risk. Properties near the Wyong River corridor and around Tuggerah Lakes need reliable photographic baselines for any modelling to hold.

For residents or developers with applications currently before council, the practical advice is straightforward. If an application involves a heritage-listed property, a flood overlay zone, or a site in the Gosford CBD renewal precinct, it is worth confirming with the council's development assessment team that the imagery attached to the property record has been verified as part of the current audit. Council's customer service centre on Mann Street can direct enquiries to the relevant assessment officer. Getting that confirmation in writing adds a paper trail that protects applicants if a decision is later challenged on the basis of incorrect documentation.
