Cairns Regional Council confirmed this week it is rolling out a new automated deduplication system across its internal digital media library, ending a backlog that had accumulated more than an estimated 40,000 duplicate images across planning, heritage, and infrastructure files since the council's last major IT overhaul in 2019. The move comes after repeated complaints from development assessment officers that duplicate files were slowing document retrieval for applications lodged through the MyDAS2 online portal.
The timing matters. The council is currently processing a high volume of development applications ahead of the state government's revised Far North Queensland Regional Plan, which sets new guidelines for coastal and reef-adjacent construction. Delays in document management have flow-on effects for applicants waiting on decisions — delays that can stall construction starts, particularly for projects in growth corridors around Smithfield and the Edmonton-Gordonvale corridor.
Why the Backlog Built Up
The duplicate image problem is not unique to Cairns, but the scale here reflects years of piecemeal data migration. When Council transitioned from its legacy Pathway records system to its current integrated platform, image files were imported multiple times across different departmental folders — engineering, parks, heritage, and waste management all holding separate copies of the same site photographs. Some individual project files contained up to a dozen copies of a single drone image taken over Trinity Inlet or the Cairns CBD waterfront.
The Cairns Central Business District Heritage Survey, last updated in 2022, was among the most affected collections, with staff manually identifying and removing duplicate photographs of heritage-listed buildings along Shields Street and Spence Street during the early part of this year. That manual process was slow and inconsistent, and it exposed the need for an automated solution.
Council's Information and Communication Technology unit began scoping a deduplication tool in late 2025. By March 2026, a contract had been awarded to a Brisbane-based digital asset management firm, with implementation scheduled for the June-July period. As of this week, staff at the Cairns City Library administration hub on Abbott Street have begun the first full-system scan, which is expected to take approximately three weeks to complete.
What It Means for Local Applicants and Organisations
The practical effect for residents and businesses should be faster document processing through the council's customer service counters at 119-145 Spence Street. Development applicants, particularly those with files that include large site photography packages — common for reef-adjacent projects that require photographic evidence under Great Barrier Reef Marine Park Authority guidelines — have previously faced retrieval delays of up to five business days when assessors needed to locate the correct master image file.
Local community organisations that regularly submit heritage or environmental documentation to Council, including groups based at the Cairns and Far North Environment Centre on Shields Street, have flagged the backlog as a practical obstacle in previous submissions to Council's environment committee. The deduplication rollout should reduce those retrieval times significantly once the initial scan is complete.
Council has not yet published a formal timeline for when the cleaned library will be fully operational for all departments, but internal communications reviewed by The Daily Cairns indicate a target date of late July 2026 for the planning and development assessment units, with parks and heritage collections to follow in August. Staff training on the new file-naming and upload protocols is scheduled to run across three sessions at the Cairns Convention Centre precinct meeting rooms during the second half of July.
Residents or businesses with active development applications who are concerned about document retrieval delays can contact Council's development assessment team directly at the Spence Street offices. Council has also indicated it will publish updated guidance on its website regarding acceptable image formats and file-size limits under the new system — changes that will affect how future applications are lodged through MyDAS2.
