Wollongong's Digital Asset Problem: The Numbers Behind the City's Duplicate Image Crisis

Wollongong City Council's digital asset library contains more than 47,000 individual image files, according to internal records tabled at the June 2026 ordinary council meeting. Of those, council staff have identified roughly 12,000 as probable duplicates — low-resolution copies, near-identical shots taken seconds apart, or the same promotional photograph saved under different file names across multiple departments. The cost of storing, managing and licensing that redundant material runs to an estimated $180,000 per year when staff time, cloud storage fees and third-party software licences are factored in.

The issue is sharper now because the council is mid-way through a $2.3 million digital transformation program, with a deadline to consolidate all communications assets onto a single platform by March 2027. Duplicate images don't just inflate storage bills — they create legal exposure. When a photograph appears in multiple folders under different metadata tags, tracking whether a licence has expired or a subject's consent has lapsed becomes genuinely difficult. The same risk applies to any organisation in the region managing a large public-facing image library.

What the Local Data Actually Shows

The University of Wollongong's library and information science faculty completed a sector audit in April 2026 covering 23 mid-sized regional councils across New South Wales. The audit found that, on average, 26 per cent of images in a council's digital asset management system qualify as functionally duplicate — meaning a human reviewer could not distinguish them by content or purpose. For Wollongong, the figure sits at 24 per cent, slightly below that average but still significant given the sheer volume of files accumulated since the council adopted its first digital asset policy in 2011.

Storage costs tell part of the story. Microsoft Azure cloud pricing for the council's current tier works out at approximately $0.023 per gigabyte per month. Duplicate image files alone are consuming an estimated 4.2 terabytes of that allocation — a figure the council's ICT team flagged in a March 2026 infrastructure report. Multiplied across 12 months, that single line item costs ratepayers roughly $1,160 in direct cloud fees, a small number in isolation but symptomatic of a wider pattern that scales dramatically across larger portfolios.

Commercial operators in the Crown Street Mall precinct and along Keira Street face the same problem at a smaller scale. Several businesses in Wollongong's CBD that rely on social media content — cafes, retailers, event spaces — use shared Dropbox or Google Drive folders that have never been formally audited. Digital marketing consultants operating out of the Innovation Campus on Squires Way say they routinely find folder structures bloated with duplicates when onboarding new clients, adding three to five hours of unbillable clean-up work per engagement before any actual campaign work begins.

What Organisations Can Do Now

Automated deduplication tools have become significantly cheaper in the past two years. Software such as Adobe Experience Manager's built-in hash-matching function, or standalone tools like Gemini 2 for smaller operators, can scan a library and flag duplicates within hours rather than weeks. The catch is that automated matching produces false positives — photographs that look identical to an algorithm but represent different events or different subjects — so human review remains mandatory before any file is permanently deleted.

For Wollongong City Council, the practical timeline is tight. The March 2027 platform consolidation deadline means the deduplication work needs to be substantially complete by December 2026 to allow time for migration testing. Port Kembla-based community groups receiving Illawarra Shoalhaven Regional Development Fund grants for digital communications projects should treat this as a prompt to audit their own image libraries now, before assets are carried forward into new platforms and the problem compounds. Starting a folder audit with a free tool, tagging files by date and photographer, and establishing a single naming convention costs nothing and prevents years of accumulation. The numbers make the case clearly enough.
