Central Coast Council's Digital Asset Overhaul: What Happened This Week With Duplicate Image Replacement

Central Coast Council confirmed this week it has moved into the active remediation phase of a long-running project to identify and replace thousands of duplicate images cluttering its digital asset management system — a backlog that has complicated planning applications, delayed public-facing website updates, and frustrated staff working on the Gosford CBD renewal precinct.

The timing matters. Council is under sustained pressure to demonstrate operational competence after emerging from state-appointed administration in 2021 following a financial crisis that left it with a debt load that, at its peak, exceeded $560 million. Rebuilding public trust has meant tightening every internal system, and the digital records estate — long neglected — has become a test case for whether the organisation can run itself cleanly.

What the Clean-Up Actually Involves

The duplicate image problem accumulated over more than a decade of siloed record-keeping across council's former northern and southern area offices, which merged when the Wyong Shire Council and Gosford City Council amalgamated in May 2016. Staff were often uploading the same site photographs, heritage assessments, and infrastructure inspection images to multiple folders across different platforms, meaning a single drainage culvert on Mardi Road or a heritage facade on Mann Street in Gosford central might have four or five near-identical image files sitting in separate directories under different filenames.

This week's work focused on three specific asset categories: planning application support photographs, flood-mapping imagery tied to the Tuggerah Lake and Brisbane Water catchments, and promotional images used across the Your Central Coast engagement portal. Council's information management team, operating out of the administration centre on Wyong Road, Gosford, ran automated deduplication software across approximately 140,000 image files, flagging around 23,000 as confirmed or probable duplicates requiring manual review before deletion or archiving.

The flood-mapping images carry particular weight right now. With climate resilience planning accelerating across the region — and Sydney recording its hottest June in more than 160 years raising alarm about intensifying weather patterns on the coast — having clean, non-duplicated baseline imagery for catchment areas around Ourimbah Creek and Toukley foreshore is not a bureaucratic nicety. It directly affects the accuracy of inundation modelling that feeds into development controls.

What Residents and Developers Can Expect Next

The practical consequence for anyone lodging a development application through the NSW Planning Portal for a Central Coast address is that supporting image packages attached to council's standard advice should become more consistent from late July onwards. Previously, automated responses sometimes pulled duplicate or outdated site photographs that did not match current conditions — a known irritant for architects and certifiers working on projects along the Gosford waterfront and in the Kariong growth corridor.

Council's digital records project runs in parallel with a broader push to digitise and centralise heritage inventory files for the Gosford Heritage Conservation Area, bounded roughly by Mann Street, Baker Street, and the Gosford railway station precinct. Those files contain architectural photographs dating to the 1980s, many of which exist only as low-resolution scans with multiple copies spread across legacy drives.

The deduplication contract, awarded earlier this year under council's existing ICT services panel arrangement, is scheduled to complete its first-pass review by 31 August 2026, with a second-pass quality audit due before the end of the calendar year. Assets flagged for deletion will be held in a quarantine folder for 90 days before permanent removal, giving departmental teams a window to rescue any files incorrectly flagged.

For residents, the most visible change will be on the Your Central Coast website itself, where planning maps, flood overlays, and project gallery images have occasionally shown inconsistent or repeated photographs. The remediation team expects the public-facing image library to reflect the cleaned database within six to eight weeks of the first-pass review completing. Anyone with specific concerns about whether historical site photographs relevant to a pending application have been incorrectly flagged can contact council's records management team at the Wyong Road offices directly.
