How Central Coast Council's Website Ended Up With Hundreds of Duplicate Images — and What It's Doing About It

Central Coast Council is undertaking a systematic audit of its digital asset library after years of rushed content uploads, a turbulent administration period, and at least two major website migrations left its public-facing platforms carrying hundreds of duplicate and orphaned image files. The cleanup, which began in earnest in early 2026, is now part of a broader push to prepare the Council's digital infrastructure for the planned Gosford CBD renewal communications rollout later this year.

The duplication problem did not appear overnight. It is the product of roughly a decade of incremental publishing decisions made across two legacy content management systems before the current platform was adopted. Staff uploading event photos for venues like the Gosford Regional Gallery or community notices tied to the Wyong Town Centre precinct frequently re-uploaded images already sitting in the library, because search functionality inside the old systems was poor and cross-departmental coordination was limited.

Administration Left a Messy Digital Inheritance

The Council's period of external administration — which ran from October 2020 after a financial crisis that left it carrying a reported debt position requiring state government intervention — made the situation significantly worse. During that period, normal content governance processes were suspended or deprioritised as administrators focused on financial stabilisation. Staff turnover was high. Institutional knowledge about which image folders held canonical versions of key assets, including maps of the Entrance Road corridor and photographs from Lake Munmorah infrastructure projects, was lost as people left.

When elected councillors returned in December 2021 and the organisation began rebuilding, digital housekeeping sat well down the priority list. Departments resumed publishing at their own pace, often pulling images from different points in the archive without checking whether a cleaner version existed elsewhere. By mid-2024, the Council's media library had accumulated multiple versions of frequently used images — aerial shots of Gosford Waterfront, before-and-after renders of the Mann Street streetscape upgrades, flood mapping graphics from the Tuggerah Lakes catchment — with no clear tagging to identify the authoritative file.

The practical consequences go beyond aesthetics. Duplicate images inflate storage overhead, slow page load times, and create version-control problems when the Council needs to update official documents or promotional material. When the team preparing community consultation materials for the Gosford CBD master plan tried to locate the correct approved render of the Central Coast Conservatorium precinct in late 2025, staff found at least four versions of the same image file sitting under different folder names.

What the Audit Involves — and What Comes Next

The current audit is working through approximately 14,000 assets in the Council's content management system, according to the Council's published digital strategy update from March 2026. Staff are using a combination of automated hash-matching tools — which detect pixel-identical files regardless of what they are named — and manual review for images that are near-duplicates rather than exact copies. Photographs of the Mingara Recreation Club, the Gosford train station precinct, and the Wamberal Beach erosion zone have all been flagged as categories with multiple redundant entries.

The Council has not yet set a public completion date for the full deduplication process. However, the March 2026 strategy document flagged that a cleaned and retagged asset library is a precondition for launching the new community engagement portal tied to the Gosford CBD renewal project, which is expected to go live before the end of 2026.

For residents and community groups that regularly access Council documents — including local bushfire recovery committees operating out of Somersby and community housing advocates referencing planning overlays around Wyong — the practical advice from digital records managers is consistent: always download a fresh copy of any Council-published map or render rather than relying on a cached version, because the audit is actively replacing outdated files with corrected ones. The Council's current website notes that published documents may be updated without notice during the transition period.

The cleanup is unglamorous work. It is also overdue.
