Townsville Council Moves to Fix Duplicate Image Problem Plaguing City's Digital Infrastructure This WeekUpdated

Townsville City Council confirmed this week it is actively working through a backlog of duplicated images embedded across its digital infrastructure, after an internal audit flagged the problem as a material risk to public record accuracy. The issue, which has accumulated over several years of overlapping system migrations, affects everything from property record photographs on the Council's asset management portal to community consultation maps published on the planning hub at the Ogden Street civic precinct.

The timing matters. Council is mid-way through a broader digital transformation program tied to its 2024–2028 Corporate Plan, and duplicated image files are creating mismatches in asset registers — particularly for infrastructure rebuilt or upgraded after the catastrophic 2019 floods. When a drainage culvert on Deeragun Road is photographed at three different stages of repair and each version sits in the system as an active record, field crews checking maintenance histories can pull the wrong image and misread a structure's condition. That is not a hypothetical; it is the precise scenario the audit identified as a repeating pattern.

Council's Information Management team, based at the Walker Street administration building, began a systematic deduplication process on Monday using software already licensed under an existing contract with the Queensland Government's whole-of-government ICT panel. The program flags near-identical image files by pixel hash comparison, then routes flagged pairs to a human reviewer before any deletion is confirmed. No image tied to a live asset record can be removed without sign-off from the relevant infrastructure or parks directorate.

Why the Flood Recovery Link Raises the Stakes

The 2019 floods left more than 4,500 residential and commercial properties requiring some form of damage assessment, according to figures published at the time by Queensland Reconstruction Authority. Council photographed affected infrastructure extensively — stormwater channels along Rossiter Road, retaining walls through Kelso, park furniture along the Riverside Boulevard foreshore — and those images were uploaded in batches, often by different teams using different naming conventions. The result was a database where the same cracked pipe could appear under three filenames with three different date stamps.

The deduplication project is not just about tidiness. Council is currently preparing asset condition reports to support its next round of capital works funding submissions to the state government, with a submission window opening in September 2026. Inaccurate or duplicated photographic records attached to those submissions could undermine confidence in the data, or worse, lead to funding being directed at infrastructure already remediated.

James Cook University's Digital Futures Lab, located on the Bebegu Yumba campus on University Road, has been engaged in an advisory capacity — not as a contractor — to review the methodology Council is using for image classification. The Lab has existing research partnerships with several north Queensland local governments on spatial data integrity, and its involvement adds independent technical scrutiny to what could otherwise look like a purely internal housekeeping exercise.

What Residents and Contractors Should Expect

The practical effect over the next four to six weeks will be intermittent unavailability of certain map and photo layers within the Council's public planning portal. A notice posted on the portal on Thursday, July 3, flagged that the Aitkenvale and Mount Louisa property layers may be temporarily incomplete during the review. Council's customer service centre on Flinders Street confirmed on Friday that development application lodgements would not be affected, as those records sit in a separate document management environment.

Property owners with active development applications were advised to contact the planning team directly if they believe a site photograph attached to their file looks incorrect — a realistic concern given the duplication patterns found in the eastern suburbs and northern growth corridors around Bohle Plains.

Council has not put a public completion date on the project, but the September funding submission deadline is the operational forcing function. Anyone needing certified asset condition images for insurance, valuation or legal purposes in the interim should request a formal record extract rather than relying on the portal's public-facing image viewer until the audit is complete.
