Cairns Regional Council confirmed this week that an internal audit of its digital media holdings identified more than 400 duplicate image files across its public-facing website and internal document management system — a problem that has quietly inflated storage costs and caused confusion in at least two planning applications lodged through the Spence Street civic precinct office in recent months.
The issue surfaced after council's ICT team, working alongside the records management unit at Level 5 of the Library and Council administration building on Sheridan Street, flagged repeated instances of the same aerial photographs appearing under different file names in submissions to the Cairns Planning Scheme portal. In at least one case involving a development near the Cairns CBD waterfront, planners were cross-referencing what they believed were two separate site photos, only to discover both images were identical files uploaded at different stages of the assessment process.
Why It Matters for Local Planning and Community Records
The timing is awkward. Council is midway through a digital transformation program that is supposed to streamline how the public accesses infrastructure data, Reef-adjacent land use records, and community consultation documents — particularly those tied to First Nations engagement under Queensland's ongoing treaty process. Duplicate or mislabelled images in those records create real risk: a community group reviewing consultation materials for a proposed development near the Yarrabah road corridor, for instance, could be looking at outdated site images without knowing it.
The council's digital asset management system, which runs on a platform procured in the 2023–24 financial year, was intended to centralise image holdings from multiple departments including Planning, Parks and Gardens, and the Cairns Airport precinct liaison team. According to the audit summary tabled at the June 30 ordinary council meeting — the last before the mid-year recess — the duplication problem is concentrated in files uploaded between January 2025 and April 2026, a period when three separate teams were granted simultaneous upload access without a standardised naming protocol in place.
Council's records team has flagged that roughly 60 gigabytes of storage is tied up in redundant files, across roughly 430 confirmed duplicates. While 60GB is modest by commercial standards, the council's current cloud storage contract — renewed in October 2025 — charges on a tiered basis, and the audit notes the system is approaching a billing threshold that would trigger a higher monthly rate if not resolved before the end of the July quarter.
The Fix, and What Residents and Developers Should Know
The ICT team has begun a systematic deduplication sweep using automated hash-matching software, with manual review reserved for files attached to active planning applications. Council has asked anyone who downloaded site images or aerial photos from the planning portal between January 2025 and this week to verify the file dates on any documents before submitting them as part of formal submissions. This applies particularly to applications in flood-prone areas around Manoora and Westcourt, where stormwater infrastructure images have been among the most frequently duplicated files.
The Cairns Local Disaster Management Group, which draws on council's digital asset library for its public communications during cyclone season, has been separately briefed. The group's preparedness cycle for the November-to-April season means any unresolved image labelling errors need to be cleared well before October, when pre-season community briefings typically begin at venues including Cairns Convention Centre and local SES units across Edmonton and Gordonvale.
Council's ICT director is expected to report back to the full council at the August ordinary meeting with a completion timeline for the deduplication project and a proposed protocol to prevent recurrence. In the meantime, residents seeking specific infrastructure or site imagery for formal submissions are advised to contact the Planning and Environment counter on Spence Street directly, rather than relying solely on portal downloads, until the audit is complete.
