How Duplicate Property Images Became Central Coast Council's Latest Headache: The Full Story

Central Coast Council is dealing with a backlog of duplicate property images embedded across its digital asset management system, a problem that traces directly to the chaotic 2020–2021 period when the council collapsed into state administration and key technology contracts were either frozen, duplicated or allowed to lapse without proper handover documentation.

The issue matters now because the council, which formally exited state administration in April 2023, is mid-way through a $150 million asset rationalisation program and has committed to a fully audited digital infrastructure by the end of the 2026–27 financial year. Duplicate imagery in planning and property databases is not just an aesthetic annoyance — it inflates data storage costs, creates errors in development application assessments, and undermines the integrity of the public-facing property portal that ratepayers in suburbs like Gosford, Wyong and Tuggerah use to check zoning and land status information.

A Problem Born in the Administration Years

When administrator Rik Hart took charge of the council in October 2020, one of the most immediate operational problems was the near-total absence of unified technology governance. The 2016 merger of Gosford City Council and Wyong Shire Council had never been fully bedded down at the systems level. Two separate geographic information systems, two asset databases, and two sets of photographic records of council-managed properties were still running in parallel four years after amalgamation.

The state-appointed administration froze discretionary spending, which meant a planned consolidation of those two imaging libraries — estimated at the time to cost approximately $380,000 — was shelved. Contractors who had been engaged to carry out the deduplication work were not retained. The result was that when the council came back under elected governance, it inherited a digital environment where some properties, particularly along the Mann Street corridor in Gosford CBD and around the Tuggerah Business Park precinct, carried anywhere from three to seven separate photographic records attached to the same land parcel identifier.

A council internal audit completed in late 2024 identified more than 4,200 duplicate image files across the geographic information system, according to information tabled at a council ordinary meeting. That figure has since grown as additional data migration work has surfaced older archived sets from the former Wyong Shire system.

Why It Still Hasn't Been Fixed

The delay since 2024 comes down to procurement. Central Coast Council's purchasing rules require tenders above $250,000 to go through a full open-market process, and the scope of the image replacement and deduplication project has been revised upward twice as auditors identified additional data sets. A request for tender was issued in March 2026, with submissions closing in late May. A contract decision had not been publicly announced as of 4 July 2026.

The timing is awkward. The council is simultaneously managing a significant urban renewal push in the Gosford CBD — the Gosford Revitalisation Program, run in partnership with the NSW Government's Hunter and Central Coast Development Corporation — and accurate, clean spatial data underpins everything from heritage overlays to flood mapping used in development applications. Gosford's Central Business District, particularly the blocks between Mann Street and the railway station on Brisbane Water Drive, is the focus of several multi-storey residential proposals currently in the assessment pipeline.

Housing pressure is only intensifying the stakes. Median house prices on the Central Coast reached approximately $930,000 in the March 2026 quarter, according to data from the NSW Valuer General's office, drawing more Sydney commuters into the region and pushing planning assessment volumes higher. Any systemic error in the property database has a direct line to delayed development decisions.

For residents tracking a development application or checking property data through the council's online portal, the practical advice is straightforward: if a property search returns inconsistent images or what appears to be an outdated photograph of a site, lodge a data correction request through the council's customer service centre on Mann Street, Gosford, or via the council's online service request system. The council's GIS team has been processing correction requests on a rolling basis while the broader tender process concludes. Council officers have said publicly that the deduplication contract, once awarded, is expected to take six to eight months to complete.
