The Numbers Behind Central Coast Council's Image Duplication Problem

Central Coast Council is carrying thousands of duplicate digital images across its planning, infrastructure and communications systems — and the data trail is messier than the organisation has publicly acknowledged. The problem sits at the intersection of two ongoing pressures: a council still rebuilding governance credibility after its 2020 financial administration, and a CBD renewal program that depends on accurate, audit-ready asset documentation.

Duplicate image files — photographs, scanned documents, drone survey stills and infrastructure condition records — accumulate when multiple departments store versions of the same asset without a centralised naming or deduplication protocol. It sounds like a bureaucratic footnote. It is not.

Why This Matters for Gosford Right Now

The Gosford CBD revitalisation framework, which covers the precinct roughly bounded by Mann Street, Donnison Street and the Gosford waterfront, relies on a live digital asset register to track development application progress, heritage overlays and public domain works. When duplicate images populate that register, condition assessments can reference the wrong version of a site photograph — meaning a 2022 image of a Mann Street streetscape might sit alongside a 2025 version filed under a different identifier, with no automatic flag to resolve the conflict.

Central Coast Council's own post-administration improvement program, which ran under the oversight of administrator Rik Hart before the elected council was restored in December 2021, identified records management as one of several systemic weaknesses. That improvement plan set a target of consolidating the organisation's digital records framework by the end of the 2023–24 financial year. Whether that target was met in full has not been confirmed in any publicly available council report as of July 2026.

The duplication issue is not unique to the Central Coast. A 2024 report by the NSW Audit Office on local government digital governance — covering a sample of councils across the state — found that records duplication was a contributing factor in asset valuation discrepancies at multiple councils, with some organisations holding duplicate file counts that inflated nominal storage costs by between 15 and 40 per cent. The report did not single out Central Coast Council by name in its published findings.

What the Data Shows Locally

Central Coast Council manages infrastructure assets with a reported replacement value in the billions of dollars across roads, drainage, open space and community buildings. The Gosford Waterfront Activation Project alone, which covers the strip from Leagues Club Field down to the public wharf off Dane Drive, has generated multiple rounds of photographic and survey documentation since concept design work began. Each round of survey work, if stored without a unified file management protocol, adds to the duplication pool.

Industry-standard deduplication tools used by comparable NSW councils — including Wollongong City Council and Lake Macquarie City Council, both of which have invested in digital asset management platforms in the past three years — typically reduce active file duplication by between 20 and 35 per cent in the first audit cycle, based on vendor documentation published by suppliers including Objective Corporation, an ASX-listed records management company based in North Sydney.

For a council the size of Central Coast, which serves a population of roughly 340,000 people across the former Gosford and Wyong council areas, the practical stakes include more than storage costs. Development applications lodged through the NSW Planning Portal must attach supporting imagery that matches the site address. A duplicated or mislinked image file can trigger a requisition from the Department of Planning, stalling approvals in suburbs like Woy Woy, Wyong and Tuggerah where housing supply pressure is acute.

Residents and builders tracking DA progress through the Central Coast Council development application portal on the council's website have no direct visibility into whether the images attached to their application are the most current version on file.

The council's current digital transformation roadmap, tabled as part of its Integrated Planning and Reporting framework in 2025, nominates a shift to a cloud-based document management system as a medium-term priority. The practical next step for ratepayers and anyone lodging development applications is straightforward: when submitting documentation, request written confirmation from council staff that the file reference number assigned to any attached image matches the version uploaded, and keep a timestamped copy of every file submitted.
