Council's Property Database Overhaul: What Officials, Experts and Key Figures Are Saying

Central Coast Council is under mounting pressure to clean up its property and asset image database after auditors flagged the presence of duplicate records across the council's geographic information system — a problem that planners say is slowing development assessment times in suburbs from Gosford to Wyong.

The issue surfaced publicly in recent weeks as the council, still rebuilding institutional credibility following its 2020 financial administration, works through a broader digital governance reform agenda. Duplicate imagery in council asset registers is more than a filing nuisance: it inflates storage costs, creates legal exposure during development disputes, and can cause surveyors and certifiers to reference outdated aerial photographs when assessing flood-liable or environmentally sensitive land.

Why the Timing Matters

The stakes are higher than they might seem. Central Coast sits at the intersection of two urgent pressures: a state government push to accelerate housing delivery under the NSW Housing Accord, and a well-documented history of administrative dysfunction that cost ratepayers an estimated $565 million in accumulated losses discovered during the 2020 administration period. Restoring confidence in the council's data systems is inseparable from restoring confidence in the council itself.

The Gosford CBD renewal precinct — where the council is working alongside the NSW Department of Planning on rezoning proposals along Mann Street and surrounding blocks — relies heavily on accurate cadastral mapping and up-to-date aerial records. Planners working on those sites have noted that conflicting image timestamps in the council's asset management platform, TechnologyOne, can trigger additional verification steps, adding days to assessment timelines at a moment when state government is pressing councils to approve more homes faster.

The Central Coast Regional Planning Panel, which handles development applications above certain thresholds, has not publicly attributed specific delays to duplicate imagery. But planning consultants operating in the Gosford and Tuggerah corridor have said the data quality problem is a known friction point, though none agreed to be named for this article.

What the Council and Advocates Are Saying

Central Coast Council confirmed in a statement to The Daily Central Coast that it is undertaking a data remediation project as part of its Digital Transformation Roadmap, a program that was formalised in the council's 2024-2028 Operational Plan. The council declined to specify how many duplicate image records have been identified or at what cost the remediation is being conducted.

The Central Coast Ratepayers Association, based on the Peninsula, has been watching the process closely. The association has previously called for transparent reporting on the council's IT expenditure following the administration period, and its position has not changed: any remediation project should be disclosed in quarterly budget updates to the community.

Digital governance specialists point to the Local Government Act 1993 as establishing baseline requirements for councils to maintain accurate and current records. NSW Local Government Information Management guidelines, last updated by the Office of Local Government in 2023, require councils to have documented data quality frameworks — a standard that several councils across regional NSW are still working to fully meet.

The University of Newcastle's urban and regional planning faculty, which has an established research relationship with Central Coast Council through its planning student placement program, has flagged data integrity as a systemic issue for post-administration councils in NSW. Researchers there have argued that digital asset management investment should be treated as core infrastructure spending, not discretionary IT expenditure.

For residents in flood-prone areas around Kincumber, Avoca and the Tuggerah Lakes foreshore, the practical consequences are tangible. Flood planning overlays depend on accurate and current imagery to delineate risk zones. An image database carrying duplicate or outdated records risks generating planning certificates — Section 10.7 certificates — that misrepresent a property's exposure to inundation. Those certificates are routinely used by buyers, banks and insurers to make financial decisions.

Council has indicated the remediation work will be completed before the end of the 2026 calendar year. Ratepayer advocates want a formal progress report tabled at a public council meeting, ideally before the September ordinary meeting at the Wyong chambers. The next test of whether data quality promises translate into practice will likely come when the first post-remediation development assessments are lodged in the Gosford CBD renewal zone.
