Central Coast Council's Property Image Audit Uncovers Widespread Duplicate Photo Problem Across Planning Portal

Central Coast Council confirmed this week it is working through a backlog of duplicate and mismatched property images discovered during a scheduled audit of its online planning and development portal, a problem that has frustrated applicants lodging development applications through the system since at least early 2026.

The timing matters. The council, which only exited formal financial administration in 2021 after a period of state government oversight, has been rebuilding its digital infrastructure while simultaneously managing a surge in development applications tied to the Gosford CBD urban renewal corridor and new housing releases across the Wyong growth area. A compromised image database creates real friction for planners, certifiers and residents trying to track applications through the system.

What the audit found — and where it hit hardest

Council's planning services team identified the duplication issue during a scheduled data migration check in late June. The problem appears concentrated in records linked to properties along Mann Street in Gosford, parts of the Tuggerah Business Park precinct, and several rezoned parcels near the Warnervale Town Centre — all areas that have seen elevated application volumes over the past 18 months as housing demand from Sydney commuters has pushed development activity north up the M1.

The duplicate images — in some cases the same site photograph appearing under multiple lot numbers — are believed to have originated from a 2024 system upgrade when records from two legacy databases were merged. Council has not yet confirmed a total count of affected records publicly, but internal workflows reviewed by The Daily Central Coast suggest the clean-up task is substantial enough that planning staff have been redeployed from other administrative tasks this week to prioritise it.

The issue is more than cosmetic. Under the NSW Environmental Planning and Assessment Act 1979, development applications must include accurate site documentation. Where images are misattributed — a photo of a Gosford CBD lot appearing on a Warnervale residential record, for instance — it can trigger requests for additional information from council assessors, adding weeks to approval timelines. For applicants already facing average assessment times that have stretched beyond the statutory 40-day benchmark in some categories, that is a serious cost.

Practical steps and what applicants should do now

The Central Coast Local Planning Panel, which handles applications above certain thresholds including contentious matters referred from the Gosford and Wyong local areas, has been advised of the data integrity issue. Applicants with pending matters before the panel are being encouraged to contact council's Development Assessment team at the Gosford administration centre on Mann Street directly to verify their supporting documents are correctly assigned in the system.

Council's customer service team has set up a dedicated inquiry pathway for affected applicants. Anyone who lodged a development application after January 1, 2025, and has not received a formal acknowledgement letter within 14 days of submission is being asked to follow up by phone rather than relying on the portal's automated status updates, which draw from the same image database under review.

The broader digital upgrade program, which council committed to as part of its post-administration recovery plan, has a reported budget allocation across the current four-year delivery program. Independent auditors flagged data migration risks as a medium-priority concern in the council's most recent operational review, presented to councillors at the March 2026 ordinary meeting.

For residents near Kariong, Erina, and the Gosford waterfront redevelopment zone — where new mixed-use proposals are moving through the system — the practical advice is the same: download and save your own copies of all submitted documents, cross-check the reference numbers on any council correspondence, and do not assume the portal's displayed attachments match what assessors are actually viewing. The audit is expected to conclude before the end of July, after which council says the portal will be taken offline briefly for a verified data reload.
