How Central Coast Council's Digital Records Mess Got This Bad: The Story Behind the Duplicate Image Problem

Central Coast Council is sitting on a digital records library estimated to contain thousands of duplicate property and asset images, a problem that auditors flagged as early as 2022 and that staff are still working to untangle heading into the second half of 2026. The duplication issue spans planning documents, infrastructure inspection photos, and heritage records — files that underpin everything from development assessments in Gosford CBD to stormwater maintenance schedules across the Wyong corridor.

The timing matters. Council is mid-way through a rebranding and digital modernisation push tied to its post-administration recovery plan, and property transaction volumes on the Central Coast have remained elevated since the pandemic-era migration surge that pushed median house prices in suburbs like Woy Woy and Tuggerah well above $800,000 by late 2024. Every duplicated asset record slows a development application or complicates a flood overlay check — exactly the kind of friction that residents and builders have been complaining about at public meetings since at least early 2025.

How the Duplication Built Up Over a Decade

The roots go back to the 2016 amalgamation of the former Gosford City Council and Wyong Shire Council into a single entity. The two councils ran different content management platforms — Gosford had migrated parts of its records to a newer cloud-based system, while Wyong was still operating a legacy on-premises database. When staff attempted a bulk data merge in 2017 and again in 2019, image files were imported without consistent naming conventions, creating the first large wave of duplicates. Nobody assigned a dedicated data librarian role at the time, and the work was split between the IT department at the council's Gosford administration building on Mann Street and records staff based at the Wyong office on Hely Street.

Then came administration. The NSW Government appointed administrators to run Central Coast Council in October 2020 after a financial crisis left the council more than $565 million in debt, according to the NSW Office of Local Government's public reporting at the time. For roughly 18 months, capital projects were frozen and discretionary digital infrastructure spending was cut. Staff turnover was high. The practical result for the records team was that no one was systematically tagging or deduplicating new image uploads during that period — photos from bridge inspections, park maintenance, and building compliance work piled in without proper metadata.

A secondary trigger was the Digitisation of Heritage Records Program, a NSW State Archives-supported initiative that Central Coast Council participated in from 2021 onward. The program was designed to bring fragile paper records from suburbs including Gosford, East Gosford, and The Entrance into a searchable digital archive. Scanning contractors, working to tight deadlines, uploaded batches that in some cases duplicated files already entered by internal staff. By the time the program wrapped its initial phase in mid-2023, the overlap between the heritage archive and the general asset library had become substantial.

What the Cleanup Actually Involves

Council's current records team, operating under the broader Information Management Strategy adopted in 2024, is using deduplication software to compare image hash values across the library — a technically straightforward process that becomes complicated when the same physical asset has been photographed multiple times and each version carries legitimate evidentiary value. Deciding which image to retain, which to archive, and which to delete requires human sign-off, and that is where the bottleneck sits in July 2026.

The practical stakes are immediate. Gosford CBD renewal projects — including the long-discussed activation of Mann Street's ground-floor retail precinct and the Kibble Park surrounds — generate asset records continuously, and planners need a clean image library to cross-reference site history during assessment. Similarly, flood resilience modelling for low-lying areas around Tuggerah Lakes depends on accurate, unduplicated infrastructure photography to validate drainage capacity assumptions.

Council has indicated it expects to complete the first deduplication pass on its highest-priority asset categories — stormwater, roads, and heritage-listed buildings — before the end of the 2026 calendar year. Residents or developers who believe an active application has been affected by a records discrepancy can contact the council's Records and Information team directly through the Service NSW-linked portal, or in person at the Mann Street, Gosford office.
