How Central Coast Council's property records ended up riddled with duplicate images — and what it cost ratepayers to get here

Central Coast Council's property and asset image database contains a significant volume of duplicate photograph records, a problem that administrators and elected councillors have been grappling with since at least 2022 — and one that traces its roots directly to the financial collapse that sent the council into administration in October 2020.

The duplication issue matters now because the council, which only returned to elected governance in May 2022 after nearly 19 months under state-appointed administrator Rik Hart, is mid-way through a multi-year asset management uplift program. Accurate records underpin infrastructure valuations. Inflated or duplicated image sets can distort condition assessments, skew maintenance budgets, and — in a council still climbing out of a debt hole that reached roughly $1.6 billion at its worst — those distortions have real dollar consequences for rate-payers across suburbs from Gosford to Toukley.

How the records got into this state

The origins sit in the chaotic period between 2016 and 2020. When the former Gosford City Council and Wyong Shire Council were forcibly merged by the NSW Government in May 2016 to create Central Coast Council, they brought two entirely separate digital asset management systems with them. Staff spent the following years attempting to reconcile incompatible databases while simultaneously managing one of the largest local government infrastructure portfolios in regional NSW — more than 5,500 kilometres of roads, 340 bridges and major culverts, and a sprawling network of community facilities including Gosford Regional Gallery on Mann Street and the Wyong Race Club precinct.

That reconciliation work was never fully completed before the council's finances collapsed. By October 2020, an internal review had found the organisation had been drawing on restricted water and sewer reserve funds to cover operating shortfalls — a practice that left a $89 million hole in those reserves, according to figures cited in administrator reports tabled with the NSW Office of Local Government. The state government suspended the elected council and handed control to Hart, who later brought in a second administrator, Liz Crouch, for governance oversight.

During the administration period, staff were under enormous pressure to stabilise finances, shed assets, and begin a digital transformation that management had deferred. A contract for a new enterprise asset management platform was progressed during 2021. Data from both legacy systems — and from multiple rounds of condition inspections conducted by external contractors working across the Gosford CBD renewal corridor and the Wyong town centre — was migrated in batches. Each migration batch created opportunities for duplication: the same photograph of the same drainage pit on, say, Donnison Street in Gosford could enter the new system twice if the migration script failed to recognise matching file metadata.

The cost of cleaning it up

Deduplication work is not free. Council staff and external data consultants have been working through the records systematically since at least the 2023-24 financial year, a process that competes for the same tight budget envelope that funds pothole repairs in Woy Woy and flood resilience upgrades on the Tuggerah Lakes foreshore.

The broader financial context remains sobering. Council's 2025-26 Operational Plan, adopted by elected councillors last year, included a special rate variation component tied to ongoing recovery obligations. Ratepayers in the Central Coast local government area — which stretches from the Pacific Highway corridor near Somersby in the south to Budgewoi in the north — have absorbed rate increases above the standard peg for three consecutive years as the organisation services its restructured debt.

Duplicated records may seem like a technical housekeeping matter, but for a council whose financial rehabilitation depends on accurate asset valuations feeding into its long-term financial plan, the integrity of the underlying data is foundational. The NSW Auditor-General has maintained close scrutiny of council's financial statements throughout the recovery period, and any material misstatement in asset registers carries audit risk.

Council officers have flagged that the bulk of the deduplication work across road and drainage image sets is expected to be substantially complete by the end of the 2026 calendar year. For residents, the practical upshot is straightforward: cleaner data should mean more defensible maintenance prioritisation decisions — and fewer occasions when a pothole on Karalta Road gets photographed four times and still doesn't get fixed.
