How Central Coast Council's Digital Records Ended Up in Chaos — and What It's Doing About It

Central Coast Council is partway through a methodical audit of its digital asset library after years of duplicate images and misfiled records accumulated across legacy systems — a problem that predates but was significantly worsened by the financial administration period that ran from October 2020 to May 2022.

The duplication issue is not a single event. It is the cumulative result of at least three separate data migration exercises, each of which copied files forward without first deduplicating the source material. Staff working on planning applications for sites along Mann Street in Gosford CBD, and on development files covering the Wyong employment corridor, have flagged the problem as a practical obstacle — the wrong photograph attached to the wrong lot reference can delay a determination by days while officers trace the correct image back through version histories.

How the problem built up

The administrative roots run back to the 2016 amalgamation of Gosford City Council and Wyong Shire Council into a single entity. Two separate IT environments, two document management systems and two sets of naming conventions were merged under time pressure. According to council's own post-administration review documents tabled in 2022, the amalgamation migration was never fully reconciled, leaving orphaned files and duplicate image sets scattered across network drives.

The financial crisis that triggered the appointment of administrator Rik Hart in October 2020 made things worse. During the administration period, several IT projects were deferred or cancelled to preserve cash. A planned upgrade to the council's geographic information system — which underpins the image records attached to property files — was pushed back twice. By the time elected councillors returned in May 2022, the backlog of unresolved duplicate assets had grown substantially, though council has not published a precise figure for the total number of affected files.

Climate-related pressures compounded the workload. After the March 2021 floods that inundated parts of Tuggerah, Wyong and low-lying areas near the Entrance Road, council officers processed an unusually high volume of emergency inspection photographs. Many were uploaded by field staff using mobile devices that were not synced to the primary document management system, then uploaded again by office staff — creating straight duplicates. Gosford's waterfront precinct around Leagues Club Field also generated duplicate survey imagery during the Central Coast Stadium precinct planning process.

What the audit involves and what comes next

The current audit, which council confirmed is underway as part of its broader digital transformation program, focuses first on images attached to Development Applications lodged after January 2019 — the period most affected by the amalgamation migration issues. Staff are cross-referencing file metadata against the council's property database, which is indexed by lot and deposited plan number, to identify and flag duplicates for removal or archiving.

Heritage listings present the most sensitive strand of the work. Images attached to properties on the Central Coast Local Environmental Plan 2022 heritage schedule — which includes buildings in East Gosford and along the Pacific Highway corridor through Ourimbah — must be individually verified before any file is removed, because a misfiled deletion could strip the evidentiary record supporting a heritage listing.

For residents and businesses lodging development applications at the Gosford or Wyong council service centres, the practical advice from planning staff is to ensure that any photographs submitted with a DA include a clear naming convention — ideally the lot number and street address in the file name — rather than the default label assigned by a smartphone camera. That single step, council's planning team has indicated through its public lodgement guidance, reduces the chance of an image being miscategorised during upload.

The broader digital transformation program is scheduled to reach its next milestone in the third quarter of 2026, when council expects to complete migration to a unified enterprise content management platform. Whether the duplicate image audit is finished before that migration matters: moving unresolved duplicates into a new system would simply carry the problem forward for a fourth time.
