Central Coast Council Tackles Duplicate Image Problem Plaguing Digital Records This Week

Central Coast Council confirmed this week it is midway through a structured cleanup of its digital records system after an internal audit found duplicate images had accumulated across multiple planning and infrastructure databases, slowing document processing times for development applications lodged through the Gosford and Wyong service hubs.

The problem matters now because the council, still rebuilding institutional capacity following its period of financial administration that ended in 2023, has been pushing to digitise more of its planning workflow as part of the broader Gosford CBD renewal push. Duplicate image files — property photos, drainage maps, road condition shots — were quietly bloating the system behind the scenes, council staff confirmed to the Daily Central Coast this week without identifying specific individuals by name.

The audit, which began in late June 2026, is being run through the council's information management team based at the Mann Street civic precinct in Gosford. Staff are cross-referencing imagery held in the council's geographic information system against documents attached to active development applications. The Wyong Road corridor and areas around Wamberal Lagoon — both subjects of intensive flood resilience and infrastructure planning in recent years — generated a disproportionate volume of duplicated field photography, according to council documents reviewed by this masthead.

What the duplication problem actually means for residents

For most residents, a cluttered image database sounds abstract. It isn't. When a homeowner in Terrigal or a developer pitching a mixed-use project near the Gosford Railway Station submits a development application, council officers need to cross-reference site photos with flood maps, heritage overlays and road condition records. If the same image exists under three different file names in three different folders, officers waste time confirming they are looking at the same asset. That delay flows downstream into assessment timeframes.

Central Coast's development assessment unit processed more than 4,200 applications in the 2024–25 financial year, according to figures published in the council's annual report. Even modest administrative friction on a fraction of those files adds up. The council's own service standard targets a median determination time of 40 days for straightforward residential applications; duplicated or misfiled supporting imagery is one of several factors staff have flagged internally as contributing to delays beyond that benchmark.

The cleanup is being handled in three stages. The first, completed by 30 June, involved automated detection software flagging files with identical pixel hashes. Stage two, running through July, requires manual review of flagged images because some near-identical photos — say, two shots of the same drain on Ettalong Beach foreshore taken a day apart — are legitimately different records needed for ongoing monitoring. Stage three, scheduled for August, will establish a new tagging protocol so field staff uploading images from tablet devices in the future attach standardised location metadata before the file hits the central server.

Broader context: digital systems and the post-administration rebuild

The council spent much of 2021 and 2022 under state-appointed administration after it ran out of money, and the hangover from that period included fragmented IT systems that were never fully integrated when the organisation expanded rapidly after the 2016 merger of the former Gosford City and Wyong Shire councils. That merger created the largest council by population in regional NSW, but the back-end digital infrastructure never kept pace.

A council spokesperson — who declined to be identified by name under the organisation's media policy — told this masthead the duplicate image project is part of a wider digital governance review that also covers document naming conventions and archival storage of older subdivision records held at the Wyong administration building on Hely Street.

Residents and applicants with active development applications can check the status of their files through the NSW Planning Portal. Anyone concerned a submitted image or document may have been misfiled should contact the council's customer service line directly at the Mann Street office. The full remediation program is expected to be complete by 31 August 2026, ahead of the council's next scheduled reporting period to the Office of Local Government in September.
