By the Numbers: Townsville's Duplicate Image Problem Is Costing Councils and Businesses More Than They RealiseUpdated

Townsville City Council's digital asset library contains tens of thousands of images. A significant portion of them — according to digital records management practitioners familiar with local government systems — are duplicates: the same photograph filed twice, three times, sometimes more, under slightly different file names. The cost is not abstract. Cloud storage pricing for enterprise accounts typically runs between $0.02 and $0.05 per gigabyte per month, and when a library balloons unnecessarily to hundreds of gigabytes, the monthly bleed adds up fast.

This matters right now because Queensland's State Government is midway through pushing councils toward centralised digital record-keeping under the Public Records Act 2023 compliance framework, with a compliance review window closing at the end of this financial year. Any organisation that cannot demonstrate a clean, de-duplicated asset register faces potential audit flags. For Townsville, already managing complex data streams from the Ross River Dam monitoring system, the RAAF Base Townsville's community liaison portals and the city's own hydrogen hub feasibility documentation, the administrative burden of redundant image files is not trivial.

What the Numbers Actually Show

Industry-standard audits of mid-sized local government digital libraries — comparable in scale to Townsville City Council's estimated 80,000-plus asset files — routinely find duplication rates of between 18 and 34 per cent. Apply the lower figure to an 80,000-file library and you are looking at roughly 14,400 files that should not exist as separate entries. At an average compressed image size of 4 megabytes per file, that represents around 57 gigabytes of redundant data. At commercial cloud rates, that is between $1.14 and $2.85 wasted every single month — before factoring in the labour cost of staff manually searching through bloated directories to find the right version of an image.

The problem is not confined to government. The Strand precinct businesses, many of which rebuilt their digital presences after the 2019 floods, uploaded imagery in bulk during recovery. Web developers working on post-flood brand rebuilds across suburbs like North Ward and Belgian Gardens noted at the time that clients were routinely ending up with three or four versions of the same shopfront photograph across different platforms — their website CMS, their Google Business profile, their Facebook page and an email marketing tool — with no single source of truth. That fragmentation makes it almost impossible to push a corrected or updated image consistently.

Local not-for-profit organisations operating under the Townsville Community Hub umbrella at Aitkenvale have faced a parallel version of the issue. Grant reporting often requires photographic evidence of program delivery. When images are duplicated across shared drives without consistent naming conventions, staff spend time they do not have verifying which version of a photograph is the approved, unedited original. That is time billed against program budgets, not toward community outcomes.

What Fixing It Actually Takes

The practical solution is a duplicate image detection and replacement workflow — a process most digital asset management platforms now offer as a built-in function. Tools like those integrated into platforms such as Bynder, Canto or even open-source alternatives like ResourceSpace can scan a library and flag pixel-level duplicates within minutes. A library of 80,000 images can typically be audited in under two hours on a standard server. The harder part is governance: deciding which version to keep, updating every internal link that pointed to the deleted file, and preventing the problem from recurring.

For Townsville organisations looking at this before the Queensland compliance review deadline, the practical priority is to audit before December 2026. Establish a single folder hierarchy — ideally mirroring the structure used by Townsville City Council's records management team — and enforce file naming conventions from the point of upload. Free tools including Google's duplicate file finder extensions and the open-source dupeGuru application can handle small libraries at no cost.

The numbers behind this story are unglamorous. Wasted gigabytes, fractional dollar amounts per month, hours of staff time. But across a city of roughly 200,000 people whose institutions are all simultaneously digitising, those fractions stack into something worth fixing before an auditor does the stacking for you.
