Council's Duplicate Image Audit: The Key Decisions That Will Shape Gosford's Digital Future

Central Coast Council is facing a set of concrete decisions this quarter after an internal audit identified widespread duplication across its digital asset management systems — a problem that has quietly inflated storage costs, slowed planning approval workflows and complicated the Gosford CBD renewal project's public communications rollout.

The timing matters. Council only emerged from state-appointed administration in May 2021 after a financial crisis that wiped more than $200 million from its balance sheet. Rebuilding institutional credibility means getting the basics right, including the unglamorous work of keeping digital records clean, consistent and legally compliant. Poor image and document management has already caused delays in two development application portals serving suburbs including Wyong and Warnervale, according to Council's publicly released digital transformation roadmap.

What the Audit Found — and Why It's Now Urgent

The review, conducted through Council's ICT directorate earlier this year, flagged thousands of duplicate image files spread across legacy content management systems inherited when the former Gosford City Council and Wyong Shire Council merged in 2016. That merger created one of the largest councils by area in NSW, and ten years on, the digital housekeeping bill is coming due.

The duplication problem is not trivial. Industry benchmarks from the Australian Local Government Association suggest councils with unresolved asset duplication can spend between 15 and 25 per cent more annually on cloud storage than comparable organisations with clean data governance. For a council with Central Coast's budget constraints — its 2025-26 operational budget sits at roughly $900 million — that kind of inefficiency is difficult to justify to ratepayers in Gosford, Terrigal or Toukley who are already watching their rates bills rise.

Three options are on the table. Council can proceed with a manual remediation process using existing staff, contract a specialist digital asset management firm to run a bulk deduplication project, or invest in new software — likely a Digital Asset Management platform integrated with its existing TechOne finance and property system — that automates the process going forward. Each option carries different cost, timeline and risk profiles. A staff-led manual review is cheapest upfront but would pull resources from the Gosford CBD Urban Transformation Strategy, which has its own digital deliverables tied to a state government funding agreement. The contracted specialist route could be completed fastest, with industry estimates for a project of this scale typically running between $80,000 and $150,000 depending on scope. The software investment is the most expensive but the only option that prevents the problem from recurring.

The Decisions Ahead and How They Connect to Bigger Plans

Council's technology steering committee is expected to bring a recommendation to the full council chamber on Mann Street, Gosford before the end of September 2026. That deadline is not arbitrary. The Gosford CBD renewal project, which includes a new library and community hub planned for the former David Jones site on Georgiana Terrace, requires a compliant and searchable image archive to support heritage impact statements and community engagement materials. Delays to the digital audit could push those planning documents past their lodgement window.

There is also a broader climate resilience dimension. Council has been building a geographic information system layer for flood mapping across the Tuggerah Lakes catchment and the Gosford waterfront precinct. Duplicate or mislabelled aerial imagery in that system creates real risk — planners working from the wrong version of a flood inundation map could produce advice that underestimates risk to new housing developments, at a moment when the Central Coast is still recovering from the 2021 and 2022 flooding events that inundated parts of Chittaway Bay and Ourimbah.

Ratepayers wanting to track the process can submit questions through Council's Your Voice Our Coast engagement platform, where the digital transformation roadmap is published. The steering committee's agenda is typically posted to Council's website five business days before each meeting. The September council meeting will be the one to watch — the resolution passed there will determine not just a software contract but the pace and credibility of every digital-dependent project Council has on its books through to 2028.
