Cairns Regional Council confirmed this week that an internal audit of its digital media holdings identified at least 400 duplicate or near-identical images stored across multiple content management systems, triggering an immediate replacement and consolidation program expected to be completed before the end of the financial year on 30 June 2027.
The issue matters now because the council is midway through a $1.2 million refresh of its public-facing website and community engagement portals — a project awarded to a Brisbane-based digital services contractor in March 2026. Duplicate images inflate storage costs, slow page load times, and create legal exposure when licensing metadata is inconsistent between copies. In short, the same photograph of the Esplanade Lagoon sitting in five separate folders under five different file names can carry five different rights statuses.
What the Audit Found — and Where
The review covered assets held across the council's main content management system, its Destination Cairns Tourism partnership portal, and the separate media library maintained by Cairns Libraries, which operates branches at Balaclava Road in Earlville, the city branch on Abbott Street, and the Woree branch on Draper Street. Library staff flagged the problem in May after a routine migration exercise surfaced multiple copies of the same reef and rainforest imagery that had been submitted by different community photographers over several years.
Council's digital services team subsequently ran an automated hash-comparison scan — a standard technique that checks whether two image files are bit-for-bit identical or visually near-identical — across roughly 28,000 assets. The scan returned 412 flagged pairs or clusters. About 60 per cent of those involve tourism and reef photography sourced through Great Barrier Reef Marine Park Authority promotional partnerships, where updated licensing agreements since January 2025 require that only the most current approved version of a given image be published.
The Cairns Airport precinct and the Tjapukai Cultural Park at Smithfield featured among the locations most frequently represented by duplicate sets, according to council's internal communications reviewed by The Daily Cairns. Both sites generate high volumes of submitted photography through tourism and event programs.
Practical Steps — and What Residents Can Expect
Council's digital team is now working through a three-stage replacement process. First, one authoritative version of each duplicated image is selected based on resolution, licensing clarity, and recency. Second, every web page or document linking to a deprecated copy is redirected or manually updated. Third, the master asset library is restructured with stricter naming conventions and contributor metadata requirements to prevent the problem recurring.
The work has direct flow-on effects for community groups that use council's online image bank for event promotion — a service used by organisations including the Cairns & District Chinese Association and sporting clubs along Mulgrave Road. Those groups were advised via email on 1 July 2026 that some gallery pages would be temporarily unavailable during the remediation period, with full restoration expected within six weeks.
For context on scale: a 2024 survey by the Content Management Institute found that mid-sized Australian local government websites carried an average of 340 redundant digital assets per 10,000 files, a figure Cairns sits above but not dramatically so. Storage costs for council's current cloud hosting arrangement run on a per-gigabyte model, and the duplicate files represent an estimated 180 gigabytes of redundant data, though the council has not yet published a precise dollar figure for the associated wasted spend.
Anyone who has contributed photography to council programs — including through the Reef Check Australia citizen science initiative, which operates locally out of James Cook University's Cairns campus on McGregor Road — is being asked to resubmit images through an updated portal with correct Creative Commons licensing details attached. The new submission form goes live on the council website on Monday 7 July 2026.
