The Numbers Behind the Image Problem: What Duplicate Photos Are Costing Central Coast Council's Digital Records

Central Coast Council is sitting on a digital storage problem it can measure in terabytes and dollars. An internal audit of the council's digital asset management system, conducted as part of the ongoing post-administration governance overhaul, found that duplicate images account for a significant share of the council's total media file holdings — files that cost money to store, slow down staff workflows, and create version-control headaches for teams working on everything from the Gosford CBD renewal to flood-resilience communications.

The council emerged from state-appointed administration in 2021 after a financial crisis that saw it accumulate debts exceeding $500 million. Since then, rebuilding operational discipline — including how digital assets are managed — has been a stated priority. Duplicate image files might sound like a minor housekeeping issue. They are not. In large organisations managing hundreds of projects simultaneously, duplicate media assets create real administrative drag and real costs.

What the Data Actually Shows

Across local government bodies in New South Wales, digital storage costs have risen sharply since 2020. Cloud storage pricing for enterprise clients on platforms used by councils — including Microsoft Azure and AWS GovCloud — has ranged between $0.02 and $0.08 per gigabyte per month depending on access tier and contract structure. For a council managing tens of thousands of image files across planning, communications, and community engagement functions, even a 20 percent duplication rate across a 10-terabyte library translates to roughly 2 terabytes of redundant data — costing hundreds of dollars per month for storage alone, before accounting for staff time spent locating the correct, current version of a file.

The duplication problem is particularly acute in organisations that have undergone structural upheaval. Central Coast Council consolidated from two predecessor councils — Gosford City Council and Wyong Shire Council — in 2016, merging two entirely separate digital systems, two sets of naming conventions, and two archives of photography spanning decades of community events, infrastructure projects, and planning documents. Images from the old Gosford Administration Building on Mann Street, construction photography from the Wyong town centre, and project records from the Tuggerah Business Park all entered the merged system without a standardised deduplication protocol.

The duplication rate across merged council systems in NSW has been a recurring audit finding. The NSW Audit Office, in its broader local government performance reporting, has flagged information management as a weak point for several merged councils since the 2016 amalgamations.

What It Means for Gosford and Beyond

For residents and ratepayers, the practical consequence shows up in delayed communications. Planning exhibition documents for projects along Donnison Street and the Gosford waterfront precinct have at times included outdated aerial photography — a direct result of staff pulling the wrong version from an unorganised library. Community engagement materials for flood-risk mapping in low-lying areas around Tuggerah Lake have faced similar version-control issues.

The solution is neither glamorous nor cheap in the short term. Deduplication software tools licensed for government use typically cost between $8,000 and $25,000 annually for an organisation the size of Central Coast Council, depending on the platform. Several NSW councils have moved toward centralised digital asset management platforms — including tools like Bynder and Canto — that enforce single-source-of-truth storage and flag duplicates at the point of upload.

Council's ICT and communications teams are understood to be evaluating options as part of a broader digital modernisation program tied to the Gosford CBD renewal's documentation and public engagement requirements. The Mann Street precinct redevelopment alone is expected to generate thousands of new image assets over the next three years as construction progresses.

Ratepayers who want to follow the process can track council's digital governance updates through the Central Coast Council website, where agenda papers for the Technology and Innovation Committee are published ahead of each meeting. The next scheduled meeting falls in August 2026. For a council still rebuilding trust after administration, getting the basics of information management right is less a technical question than a governance one.
