How the Central Coast Council's Image Duplication Problem Quietly Grew Into a Planning Headache

Central Coast Council is working through a sprawling cleanup of duplicate images embedded across its property, development application and community engagement platforms — a problem that traces its roots directly to the rushed 2016 merger of Gosford City Council and Wyong Shire Council, and one that has quietly complicated planning decisions ever since.

The issue matters now because the Council is mid-way through a multi-year digital transformation program that underpins everything from the Gosford CBD renewal strategy to the flood mapping updates being rolled out across low-lying suburbs near Tuggerah Lake and the Entrance. If the underlying image assets feeding those public-facing systems are duplicated, mislinked or misattributed, the practical consequence is that residents, developers and planners can be looking at the wrong reference photograph for a given site — sometimes a property photograph taken years before demolition or subdivision.

Two Councils, Two Systems, One Unresolved Mess

When the NSW Government forced the merger of Gosford and Wyong in May 2016, the two councils brought with them entirely separate content management systems, separate asset registers and separate conventions for tagging and storing images tied to development applications. Neither system was designed to talk to the other. The amalgamation created a single organisation overnight, but the digital back-end remained essentially two separate archives stitched together under one login portal.

The problem compounded during the period between 2020 and 2022 when the Council was placed under state administration following a financial crisis that left it carrying a debt load that administrators later described in public documents as unsustainable. During that period, investment in digital infrastructure was deprioritised as administrators focused on stabilising the balance sheet. Routine image auditing — matching photographs to current property records and purging outdated or duplicated files — largely stopped.

By the time elected councillors returned in December 2021, the backlog was significant. Properties along Mann Street in Gosford, around the Tuggerah Business Park precinct, and within the Wyong Town Centre renewal corridor all feature in internal working documents as areas where duplicate or mismatched images have been identified, according to Council agenda papers published on the authority's website.

What a Duplicate Image Actually Does to a DA

For most residents, a duplicate image sounds like a minor administrative nuisance. For a development application, it can be more consequential. A planning officer assessing a DA for a site on Donnison Street in Gosford, for example, relies on reference imagery to understand existing structures, setbacks and streetscape context. If two conflicting images are tagged to the same cadastral parcel — one current, one five years old showing a building that has since been demolished — the assessment record carries an error from the outset.

Council moved in 2024 to consolidate its content platform under a single vendor as part of its broader technology refresh, with the full migration initially targeted for completion before the end of the 2025–26 financial year. The duplicate image remediation work sits inside that migration project. As of the most recent publicly available Council business paper, the remediation phase was described as ongoing, with prioritisation given to parcels that have active development applications or are within the Gosford Revitalisation precinct boundary.

The timing intersects with genuine pressure on the local planning system. Central Coast remains one of the most active property markets outside metropolitan Sydney, driven by buyers priced out of the city who are willing to accept the roughly 90-minute commute from Gosford station. More DAs mean more pressure on accurate underlying records.

Residents with development applications pending — particularly those in the Gosford CBD catchment, the Warnervale growth corridor or the Hamlyn Terrace residential estates — should check with Council's planning counter that the imagery attached to their DA file reflects current site conditions. Council's customer service team operates out of the Wyong Road offices and can flag any image discrepancies for correction before assessment proceeds. Getting that check done early is considerably less painful than discovering an error once an assessment is already underway.
