Cairns Regional Council's digital asset library holds an estimated 47,000 image files, and internal audits completed in early 2026 found that roughly one in five is a duplicate — the same photograph stored under two or more file names, in two or more folders, sometimes across three separate departments. The council's information management team has flagged the problem as a priority for the current financial year, with deduplication software procurement listed in the 2025–26 ICT budget line.
The timing matters. Queensland's new Local Government Records Governance Framework, which came into effect on 1 January 2026, requires councils to demonstrate active records hygiene as part of compliance audits. Cairns, along with Townsville City Council and Mareeba Shire Council, sits inside the first audit cohort — meaning a compliance review is due before 30 September 2026. Holding redundant digital assets is not merely untidy; under the framework it can trigger a formal management improvement notice.
What the Data Actually Shows
The duplication problem is not unique to Cairns, but the scale here reflects years of rapid digitisation without a unified naming protocol. Between 2018 and 2023, the council migrated images from at least four legacy systems — including the old Cairns City Council archive on Sheridan Street, the Tropical North Queensland Tourism photo library, and the separate Planning and Development image register held at the Spence Street administration building. Each migration copied rather than replaced existing files.
Across those four systems, the council's records unit identified approximately 9,400 confirmed duplicate image pairs by March 2026. Storage costs for the council's cloud infrastructure contract — held with a provider under a whole-of-government Queensland arrangement — are charged per gigabyte per month. Duplicate images were consuming an estimated 2.3 terabytes of redundant storage, translating to a recurring annual overhead that the council's ICT team put before the Finance and Governance Committee in April 2026. The committee approved a one-off deduplication and cataloguing project, with a budget allocation understood to be drawn from the council's existing digital transformation reserve.
Staff hours are the bigger cost. The council's library and records team at the Cairns City Library on Abbott Street logged more than 340 staff hours in the 2024–25 financial year on image retrieval tasks that were complicated by duplicate or mislabelled files — cases where a planning officer, for example, requested a specific site photograph and received three near-identical versions with no clear indication of which was authoritative. At an average full-time equivalent cost of approximately $42 per hour for administrative staff, that represents roughly $14,280 in wasted retrieval labour in a single year.
What Happens Next — and What It Means for the Public
The practical fix involves three stages. First, automated deduplication software scans the library using perceptual hashing — a technique that identifies visually identical images even when file names differ. Second, a metadata standardisation pass applies consistent naming, date, and location tags, a task the council has contracted to a Cairns-based digital records firm. Third, a human review layer checks flagged near-duplicates — images that are similar but not identical, such as sequential shots of a construction site at Portsmith or multiple drone passes over the Cairns Esplanade.
The project is scheduled for completion by August 2026, ahead of the September compliance deadline. Once finished, the council expects the active image library to shrink from 47,000 files to somewhere between 28,000 and 32,000 — a reduction of roughly 35 percent. For residents, the immediate benefit is faster responses to Right to Information requests that involve photographic evidence, a category that has grown steadily since 2022 as development disputes along the Northern Beaches corridor have increased. Requests involving images took an average of 23 days to process in 2024–25, compared with the statutory 25-day target — a margin that records staff say would tighten further without the clean-up. The audit result in September will determine whether Cairns becomes a case study in Queensland's records governance program or a cautionary footnote.
