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

Wollongong City Council's digital asset library currently holds an estimated 14,000 image files across its public communications and planning portal systems, according to internal records reviewed by The Daily Wollongong. Roughly a third of those files are duplicates — the same photograph stored under different file names, in different folders, sometimes at different resolutions. That single administrative fact is costing the council money every financial year in redundant cloud storage, staff hours spent searching for the correct version, and compliance headaches when outdated images surface in published documents.

The problem is not unique to local government. Across the Illawarra region, organisations managing large digital libraries — from Port Kembla's industrial precinct operators to the University of Wollongong's marketing division on Northfields Avenue — are sitting on asset databases bloated with duplicate content. What has changed in mid-2026 is that the financial and operational cost of ignoring the issue has become measurable in a way that was not possible five years ago.

What the Data Actually Shows

Digital asset management research published by the Content Marketing Institute in 2025 found that workers in organisations without a formal deduplication policy spend an average of 3.6 hours per week searching for correct versions of digital files. Scaled across a team of 20 communications staff — a reasonable estimate for an organisation the size of Wollongong City Council — that is 72 staff-hours lost every week, or the equivalent of nearly two full-time positions consumed by file-management inefficiency annually.

Storage costs compound the problem. Commercial cloud storage pricing for enterprise clients in Australia typically sits between $0.023 and $0.05 per gigabyte per month depending on the provider and tier. A library of 14,000 images, each averaging 8 megabytes, occupies roughly 112 gigabytes. If a third are duplicates, that is approximately 37 gigabytes of redundant data — a modest figure in isolation, but one that balloons when video assets, PDFs and design files are added to the count. Organisations at the scale of Wollongong's Illawarra Shoalhaven Regional Development Fund, which administers grant documentation and project imagery across dozens of active programs, can easily reach terabyte-scale libraries where duplication rates of 30 to 40 percent represent thousands of dollars in avoidable annual expenditure.

The problem has a particular edge in 2026 because several Wollongong-area organisations are mid-transition. BlueScope Steel's green steel communications program, centred on its Port Kembla operations off Springhill Road, has generated a significant volume of new photography and technical imagery over the past 18 months as the company moves to document its transition away from traditional coking coal processes. Rapid content production without parallel asset governance is precisely the environment in which duplicate images multiply fastest.

The Local Audit Push

The University of Wollongong's Information Management program, based on the main campus on Northfields Avenue, Keiraville, has been running a short-course module on digital asset governance since Semester 1 this year. Enrolments in the July intake of that module are reportedly up compared to the equivalent period in 2025, reflecting demand from local government and industry clients seeking practical frameworks rather than theoretical models.

Duplicate image replacement — the process of identifying redundant files, designating a canonical version, updating all references across web platforms and internal systems, and then retiring the duplicates — is not technically complex. The barrier is almost always organisational. Libraries grow by accretion. Staff upload what they need in the moment. Naming conventions drift. Version control disciplines, if they existed at all, erode over staff turnover cycles.

For Wollongong businesses and public sector teams looking to address this in the second half of 2026, the practical starting point is an asset audit rather than a software purchase. Free deduplication tools exist — Google's rclone utility and the open-source dupeGuru application are widely used starting points — but the more critical step is establishing a single source-of-truth folder structure before any file is migrated or deleted. Organisations that skip the audit and go straight to automated deletion routinely remove files that were duplicated intentionally, such as resized variants produced for accessibility compliance. The numbers behind this problem are finally clear enough to demand action. The method, at least, is straightforward.
