Wollongong Councils and Businesses Are Drowning in Duplicate Images — Here's What the Numbers Reveal

Across Wollongong's business district, council offices on Burelli Street and the marketing departments of organisations tied to the Port Kembla industrial corridor, a quiet digital housekeeping crisis has been building for years. Duplicate images — the same photograph stored, managed and backed up multiple times across different servers and platforms — now account for a measurable share of wasted IT expenditure. For the Illawarra region, where public and private sector budgets are already stretched by infrastructure demands at the Port Kembla Renewable Energy Zone and the BlueScope Steel green transition, that waste is not trivial.

The timing matters. Mid-2026 is when many NSW local government bodies complete their annual digital asset audits ahead of the new financial year, making it the most common moment organisations first confront the actual size of the problem. What they are finding, according to publicly available industry data from research firm Gartner published in its 2025 digital storage report, is that unmanaged duplicate files — images chief among them — can consume between 20 and 30 per cent of an organisation's total cloud storage budget.

What the Numbers Look Like for Illawarra Organisations

For a mid-sized regional organisation spending, say, $80,000 a year on cloud storage — a figure consistent with the scale of operations at institutions like the University of Wollongong's IT services division or Wollongong City Council's digital infrastructure — that 20-to-30 per cent figure translates to between $16,000 and $24,000 spent annually on storing files that already exist elsewhere in the same system. Multiply that across the dozen or more significant employers anchored between Crown Street Mall and the Northfields Avenue university precinct, and the regional figure climbs quickly into six digits.

The mechanics of how duplicates accumulate are straightforward. When a communications team at, for example, a North Wollongong venue or a Shellharbour-based regional business uploads event photography to a shared drive, then re-exports edited versions, then attaches originals to email threads, then migrates everything during a platform switch, the same base image can exist in five or six distinct locations within months. Automated backup systems — designed to protect against data loss — then copy each version again. Without a deduplication protocol in place, the storage bill compounds.

A 2024 report from the Australian Information Industry Association found that small-to-medium enterprises in regional NSW were less likely than their Sydney counterparts to have formal digital asset management policies in place — a gap that directly correlates with higher rates of redundant file storage. The report did not name specific Illawarra businesses, but the regional NSW category in its survey covered organisations of the size and type common to the Wollongong CBD and the Illawarra Shoalhaven area.

Practical Steps and What Comes Next

The fix is not technically complicated, but it requires deliberate action. Deduplication software — tools like Gemini 2 for Mac environments or commercial enterprise solutions such as Microsoft Azure's built-in blob deduplication — can identify and consolidate redundant image files across a storage system. The University of Wollongong Library, which manages large archival image collections as part of its digital preservation work, publicly documents a collections management framework that includes periodic redundancy reviews. That model is transferable to smaller organisations.

For Wollongong businesses wanting to benchmark their own exposure, the starting point is a storage audit — most cloud platforms including Google Workspace and Microsoft 365 provide native usage analytics that break down file-type storage consumption. Running that report before the next quarterly IT budget review, particularly for any organisation that has migrated platforms or expanded its digital communications since 2022, will likely surface numbers that justify the follow-up work.

The broader point for the Illawarra economy is that green steel investment and renewable energy infrastructure are rightly dominating the regional conversation right now — but the unglamorous work of digital efficiency sits alongside those big structural shifts. Money recovered from storage waste is money available for the skills training, digital upskilling and local procurement that the region's industrial transition actually depends on.
