How Central Coast Council's Image Crisis Became a Planning Headache Years in the Making

Central Coast Council is partway through a structured program to identify and replace duplicate images embedded across its property management, development assessment, and public asset databases, a problem that administrators who ran the organisation between October 2020 and May 2022 flagged as part of broader record-keeping deficiencies inherited from the merger of the former Gosford City Council and Wyong Shire Council in May 2016.

The timing matters. With Gosford CBD renewal projects now back before Council's planning committees, and development applications around Mann Street and Kibble Park moving through the system, accurate and deduplicated site imagery is not a bureaucratic nicety, it is a legal requirement under the NSW Environmental Planning and Assessment Act 1979. An outdated or duplicated image attached to the wrong parcel record can delay a DA, trigger a review, or expose Council to challenge in the Land and Environment Court.

A Merger That Left Digital Housekeeping Undone

The 2016 forced amalgamation brought together two councils with entirely separate GIS platforms, document management systems, and photographic archives. Gosford had used one vendor for aerial and street-level property imagery; Wyong another. When staff attempted to consolidate records into a unified system, eventually settled on TechnologyOne, which Council formally adopted as its enterprise platform, thousands of image files were migrated without deduplication protocols in place. Some parcels along the Gosford waterfront and in the Tuggerah Business Park ended up carrying three or four separate image records, some dating to different seasons and different cadastral boundaries.

The administration period made things worse before it made them better. When administrator Rik Hart took control of the organisation in October 2020, following the council's effective insolvency, his team prioritised financial stabilisation over database integrity. A Operational Audit completed during the administration period, referenced in Council's published recovery documentation, noted that asset and property records required significant remediation. Image duplication was listed among the identified issues, though it was not the primary concern at a time when Council carried a debt load requiring urgent restructuring.

Elected councillors returned to chambers in May 2022. Since then, Council's records and information management team, based at the Wyong administration centre on Hely Street, has been working through a phased deduplication project. The program involves cross-referencing the TechnologyOne property module against the Council's TRIM document management repository and the NSW Valuer General's spatial datasets. Staff are required to review flagged duplicates manually before archiving or replacing them, a process that, as of the 2025-26 financial year, remains ongoing across an estimated tens of thousands of property records covering the council area's roughly 170,000 lots.

Why It's Surfacing Now

The issue has gained fresh urgency because of two converging pressures. First, the Gosford CBD revitalisation, including development activity near the Gosford Hospital precinct on Holden Street and the long-discussed activation of the former David Jones site on Mann Street, is generating a higher-than-usual volume of development applications. Each DA triggers image verification requirements. Second, the NSW Government's push to accelerate housing supply under the Transport Oriented Development program, which applies to the Gosford train station precinct within 1,200 metres, is compressing DA processing timeframes. Councils statewide were given until late 2025 to update their LEPs to reflect TOD requirements; image and record quality became part of that preparation work for Central Coast.

For residents and developers dealing with the DA system, the practical advice is straightforward: if a property assessment or pre-DA meeting references an image that appears to show a different structure, boundary, or streetscape than what exists today, raise it immediately with the assigned planner at Council's Gosford or Wyong service centres. Delays caused by image discrepancies are avoidable if flagged early. Council's customer service team can lodge a formal record correction request, which is triaged through the information management unit. Getting that request in before a DA is formally lodged, rather than after, saves weeks.
