Cairns Regional Council is undertaking a structured audit of its digital asset library after internal reviews identified thousands of duplicate images spread across two content management platforms, a problem that administrators say accumulated over at least a decade of inconsistent record-keeping practices.
The issue matters now because the council is mid-way through a $4.2 million digital transformation program scheduled for completion by March 2027, and duplicated files are inflating storage costs, slowing the migration process and creating compliance risks under Queensland's Public Records Act 2002. Resolving the backlog before the migration deadline has become a priority for the council's ICT directorate.
The trail back to how this happened runs through several distinct phases of the council's technology history. When Cairns City Council amalgamated with Douglas Shire Council in 2008, two separate digital filing structures were merged without a unified naming convention. Staff at the Spence Street civic building and those previously based in Mossman continued uploading assets independently for years after amalgamation, often using different filename formats for the same photographs of locations like the Esplanade lagoon precinct or the Cairns Botanic Gardens at Edge Hill.
A Second Wave of Duplication After 2019
A second, larger wave of duplicate content entered the system between 2019 and 2022, when the council transitioned its public-facing website to a new platform while retaining the legacy system for internal documents. Drone footage of the Trinity Inlet foreshore, promotional photography for the Cairns Convention Centre and heritage imagery from the Cairns Museum partnership all exist in multiple versions across both environments. Some image sets were uploaded three or four times by different departments with no cross-referencing in place.
Staff turnover compounded the problem. Council employment data tabled at a February 2026 ordinary meeting showed ICT and communications had a combined turnover rate of 22 percent between 2020 and 2025, meaning institutional knowledge about where files lived and which versions were authoritative kept walking out the door. New staff, unable to locate images quickly through the existing search function, defaulted to uploading fresh copies rather than hunting through poorly tagged folders.
The audit, being conducted by the council's records management team in partnership with a Brisbane-based digital governance contractor, has so far reviewed approximately 40 percent of the total asset library. Early findings presented to the council's infrastructure and ICT committee in June 2026 indicated that roughly one in three image files reviewed was a duplicate or near-duplicate of an existing asset. The council has not publicly released a total file count or the estimated storage cost of the redundant material.
What the Clean-Up Actually Involves
Deduplication at this scale is not a simple delete-and-move exercise. Queensland state archiving rules require the council to assess whether any image — even a duplicate — constitutes a public record before it can be destroyed. Images of council infrastructure, planning approvals, or community events may carry retention obligations of between five and 25 years depending on their classification under the General Retention and Disposal Schedule for Local Government.
The council's records team is working through a triage process that categorises each duplicate as either a confirmed redundant copy safe for deletion, a file requiring retention under the disposal schedule, or an ambiguous case needing human review. The last category is the most time-consuming and, according to the June committee report, currently represents about 18 percent of files reviewed so far.
For residents and local organisations that interact with council's image library — including the Cairns Indigenous Art Fair committee, tourism bodies on Abbott Street and community groups who rely on council photography for grant applications — the practical advice is to keep copies of any images supplied by the council for your own records. Until the audit concludes, the council's ability to quickly retrieve specific historical images on request may be slower than usual. The ICT directorate has indicated it expects the deduplication phase to wrap up by October 2026, ahead of the broader platform migration beginning in earnest in the new year.
