Central Coast Council is working through a backlog of duplicate digital images embedded across its asset management and planning databases, a problem that traces directly to the chaotic merger of Gosford City Council and Wyong Shire Council in May 2016 and the financial administration period that followed four years later.
The duplication issue matters now because Council is mid-way through a multi-year digital transformation program tied to its Gosford CBD renewal commitments and long-range infrastructure planning along the Mann Street and Donnison Street corridors. Accurate, clean asset records are a baseline requirement for federal and state grant applications — and duplicated images attached to the wrong parcels or infrastructure items can trigger assessment errors and delay funding approvals.
Two Councils, Two Systems, One Unresolved Mess
When the state government forced the merger of Gosford and Wyong councils on 12 May 2016, the new entity inherited two entirely separate IT environments. Gosford had been running one asset management platform; Wyong operated another. Photographs of drainage infrastructure in Tuggerah, footpaths in Bateau Bay, and development application imagery from the Gosford waterfront were migrated in bulk rather than audited line by line. Council staff at the time were dealing with a 1,400-square-kilometre operational area and a combined workforce that had never worked under a single system.
The crisis deepened between October 2020 and May 2023, when the NSW Government placed Central Coast Council into financial administration after the organisation ran a cumulative deficit that administrators later pegged at more than $565 million. During that period, the majority of non-essential IT projects were suspended. Database maintenance — including deduplication work on the image libraries attached to Council's geographic information system — was among the casualties. Staff numbers in the digital records team shrank. The backlog grew.
Specific locations felt the knock-on effects. At Gosford's Central Plaza development precinct on Mann Street, planning officers pulling historical imagery for development applications repeatedly encountered mismatched files — photos labelled to one cadastral parcel but physically showing an adjoining lot. At the Tuggerah Business Park, infrastructure teams reported similar problems when trying to cross-reference drainage asset photographs with field inspection records.
The Scale of the Problem and What Comes Next
Council has not published a formal public figure for the total number of duplicate records, but the issue sits within the broader scope of its Digital Transformation Strategy, which was publicly adopted as part of the organisation's post-administration recovery framework. The strategy identifies data integrity across the asset register as a priority workstream, with milestones tied to the 2026–27 financial year.
The problem also has a climate dimension. As the Central Coast develops its flood risk and climate resilience planning — particularly for low-lying areas around Tuggerawong Road and the Wyong River floodplain — accurate photographic records of drainage assets and levee infrastructure are not optional. NSW's extreme weather run, including Sydney's record June temperatures recorded this week, has accelerated pressure on councils across the state to have defensible, audit-ready asset registers before the next Infrastructure NSW funding round opens.
For residents and property owners, the practical consequence is straightforward: development applications that rely on Council's geographic records — including those in the Gosford CBD renewal zone bounded by Donnison Street, Baker Street, and the waterfront — may face longer assessment times if staff must manually verify image provenance before attaching records to a file.
Council's technology and information directorate is understood to be running a staged remediation process through the second half of 2026, prioritising assets in high-growth and high-risk zones first. Property owners lodging DAs in the Gosford and Wyong town centres are advised to include their own site photography with submissions to reduce the chance of a records mismatch causing delays. The full deduplication project is expected to carry into the 2027 calendar year.
