Townsville Councils Sitting on Thousands of Duplicate Digital Images — and It's Costing Ratepayers Real MoneyUpdated

Townsville City Council is carrying an estimated 340,000 duplicate image files across its asset management and planning databases, according to a data audit completed by its ICT division in May 2026 — a problem that has ballooned storage costs and undermined the accuracy of records used to manage everything from road maintenance on Woolcock Street to flood resilience planning on the Ross River corridor.

The audit matters now because Townsville is mid-way through a $4.2 million digital transformation program tied to its 2025–2030 Smart City Strategy. That program depends on clean, deduplicated data. When image libraries are clogged with redundant files — sometimes the same aerial photograph of a suburb like Kirwan or Mount Louisa stored six or seven times under different file names — the downstream effects hit procurement, infrastructure planning, and community reporting.

What the Numbers Actually Show

The May audit found that duplicate images accounted for roughly 28 percent of total storage consumption inside Council's document management system, which runs on a Microsoft SharePoint environment integrated with the TechOne civil asset platform. Each terabyte of unmanaged cloud storage costs Council approximately $340 per month under its current Optus government framework contract. Across the duplicated image load — estimated at around 18 terabytes — that translates to a recurring waste of just over $6,100 monthly, or more than $73,000 a year.

The problem is not unique to Townsville. A 2024 benchmarking report by the Local Government Association of Queensland found that councils with populations between 100,000 and 250,000 residents — Townsville sits at around 197,000 — carried duplicate digital asset rates averaging between 22 and 31 percent. Townsville's 28 percent figure puts it squarely in the middle of that range, but the absolute dollar figure is higher than comparable-sized councils because of the volume of aerial and drone imagery generated during post-flood asset reassessment work following the catastrophic 2019 floods.

James Cook University's eResearch Centre at the Douglas campus has been working with Council under a data governance partnership established in March 2025. Researchers there flagged the image duplication issue as a priority after running a pilot deduplication scan across just three of Council's 14 active project folders — finding 4,800 redundant files in a single afternoon. That pilot cost nothing beyond staff time. The full remediation project, now underway, is budgeted at $118,000 and is expected to recover approximately 14 terabytes of storage by the end of September 2026.

What Happens When Data Gets Messy

The practical consequences go beyond a line item on a storage invoice. Council planners working on the Townsville Hydrogen Hub precinct near the Port of Townsville have flagged that asset imagery mismatches — caused partly by duplicates with incorrect metadata — created a two-week delay in a site assessment report submitted to the Queensland Department of Energy in February 2026. That kind of bottleneck matters when hydrogen project timelines are tied to state and federal funding milestones.

The RAAF Base Townsville and Lavarack Barracks precincts also appear in Council's geographic information system imagery, and duplicated or mislabelled aerials of buffer zones around those sites have occasionally surfaced during public-facing planning portal searches — a compliance issue Council's legal team has since flagged for urgent resolution under the Defence Facilities Exclusion Protocol.

For residents, the most direct advice is straightforward: if you have submitted images with development applications or flood damage claims through Council's online portal on Flinders Street, and you received an acknowledgment with a reference number before June 2026, Council's ICT team is asking that you do not resubmit files unless specifically requested. Duplicate submissions from the public have contributed an additional estimated 12 percent to the image duplication load. Council's online portal now carries a banner warning against resubmission, and a full remediation progress report is expected to go before the Planning and Development Committee at its August 11 meeting.
