Central Coast Council Moves to Fix Thousands of Duplicate Property Images This Week

Central Coast Council confirmed this week it is working through a backlog of duplicate and mismatched images in its property information database, a technical problem that has dogged the system since the 2020 merger of the former Gosford City and Wyong Shire councils consolidated two separate record-keeping platforms into one.

The timing matters. Council's planning and development division is under pressure to speed up assessments as the Gosford CBD renewal program accelerates, with several mixed-use towers on Mann Street and Baker Street now in various stages of development application review. Duplicate property images — where the same aerial photo, site plan or heritage photograph appears multiple times under a single lot reference, or worse, under the wrong lot entirely — can trigger manual cross-checks that add days to already stretched assessment timelines.

What the Problem Actually Looks Like on the Ground

The issue is not purely cosmetic. When a homeowner in Woy Woy or a developer with a site in Tuggerah pulls up a property record through the Council's online portal, a duplicated image attached to the wrong lot number can create confusion about zoning overlays, flood mapping annotations or heritage listing boundaries. In flood-prone areas along the Wyong River corridor and around Gosford's waterfront, that kind of records error carries real planning risk as the region builds out its climate resilience frameworks.

Council's records and information services team began the deduplication work in the last week of June 2026, according to internal scheduling documents referenced in a Council communiqué circulated to planning staff. The process involves automated flagging of image files sharing identical metadata signatures, followed by manual review for any record where an image is linked to a heritage or flood overlay. The work is expected to run through July and into early August.

The Central Coast's property database holds records for more than 160,000 lots across the local government area, which stretches from the Hawkesbury River boundary in the south to Lake Macquarie in the north. Even a small error rate across that volume generates a substantial manual workload. Council has not publicly disclosed how many duplicate image records were identified at the start of the project.

Why It Connects to Bigger Council Priorities

Council only exited formal financial administration in 2021 after a period under state-appointed administrators following a budget crisis. Rebuilding public confidence in its administrative systems has been an ongoing task since, and the property records database has been one of the more visible pain points for residents dealing with the planning department.

The Gosford CBD specifically is a focal point. The state government's Gosford Activation Plan, which has drawn attention to sites along Donnison Street and the waterfront precinct near Kibble Park, depends on accurate and accessible property data for investors and certifiers assessing development potential. A duplicated or misattributed site image attached to a heritage lot on Baker Street, for instance, could stall a pre-lodgement inquiry at a sensitive moment for the renewal effort.

The deduplication project also dovetails with Council's ongoing preparation for the next round of flood-risk mapping updates expected later in 2026. Properties along Narara Creek, around the Tuggerah Lakes foreshore and in low-lying parts of Wyong township are subject to updated overlays following recent hydrological modelling. Clean, correctly attributed imagery in those records is a baseline requirement before new flood annotations can be reliably applied.

For homeowners, the practical step right now is straightforward: if you are preparing a development application, a section 10.7 planning certificate request, or a pre-purchase property search for a Central Coast address, it is worth calling Council's development advisory service at the Gosford office on Mann Street to confirm that the imagery attached to your lot reference is current and correctly attributed before lodging. Council's customer service team can flag a record for priority review if an error is identified ahead of a time-sensitive submission.
