The Numbers Don't Lie: Melbourne's Duplicate Image Problem Is Costing Councils and Businesses Millions

Melbourne organisations are sitting on a digital hoarding problem they can barely measure. Across local councils, arts institutions and small businesses, duplicate image files — the same photo saved twice, three times, sometimes dozens of times under slightly different file names — now account for an estimated 30 to 40 per cent of total digital storage consumption, according to industry benchmarks published by data management firm Komprise in its 2025 Global Unstructured Data Management Report. At current enterprise cloud storage rates in Australia, hovering around $0.023 per gigabyte per month on AWS S3 Standard, the waste compounds fast.

The issue has landed with fresh urgency because the Victorian Government's Digital Victoria strategy, which set a 2026 target for agencies to audit and rationalise unstructured data holdings, is now at its deadline. Several Melbourne-based councils and state agencies are scrambling to demonstrate compliance before the end of the 2025–26 financial year — a deadline that passed on June 30.

Where the Bloat Lives

The City of Melbourne alone manages tens of thousands of asset images — photographs of infrastructure, public art installations, planning documents and event records stretching back more than a decade. Its digital asset management system, which the council has been migrating to a cloud-hosted platform since early 2024, is one of the largest municipal image repositories in Victoria. Fitzroy-based digital archiving consultancy Smaller Picture, which has worked with Melbourne arts organisations including the Gertrude Contemporary gallery on Smith Street, estimates that arts sector clients typically find between 28 and 45 per cent of their image libraries consist of duplicates or near-duplicates — images that differ only in resolution, compression level or metadata tag.

The Footscray Community Arts Centre undertook a digital audit in late 2024 and found that its image archive had ballooned to more than 2 terabytes, a figure that staff described in published board notes as significantly larger than expected. Best-practice deduplication tools — software that scans for pixel-level or hash-matched copies — can typically reduce such archives by 20 to 35 per cent, according to technical guidance published by the Australian Signals Directorate's Information Security Manual, which addresses data hygiene alongside security controls.

The Cost of Doing Nothing

Run the numbers and the picture sharpens quickly. A mid-sized Melbourne business storing 10 terabytes of image data on a standard cloud platform pays roughly $2,760 a year. If 35 per cent of that storage is duplicated, the organisation is burning through approximately $966 annually on files it already has. Multiply that across the 27 councils in metropolitan Melbourne, each with growing digital asset libraries, and the aggregate waste runs into the low millions every year — before accounting for the staff time spent searching through redundant files.

The problem is not just financial. Victoria's Information Privacy Act 2000 creates compliance exposure when outdated or duplicate images of identifiable people — captured at community events, for instance, or in planning consultation records — persist in multiple locations across an organisation's systems. Each copy is a separate data liability. The Office of the Victorian Information Commissioner has flagged in successive annual reports that data minimisation remains one of the weakest areas of compliance across Victorian public sector agencies.

Deduplication software products capable of scanning large image libraries — including tools from vendors such as Canto, Bynder and open-source options like dupeGuru — range from free to roughly $1,500 per year for a mid-tier commercial licence. Most Melbourne IT managers contacted for this story said their organisations had no formal deduplication policy in place, relying instead on ad hoc manual processes. That gap is exactly what Digital Victoria's 2026 audit requirement was designed to close.

Organisations that have not yet completed a data audit face the practical question of where to start. The Victorian Government's Engage Victoria platform published guidance in March 2026 directing agencies toward a phased approach: inventory first, deduplicate second, then establish naming conventions that prevent the problem from rebuilding itself. For small businesses in suburbs like Collingwood or Richmond, the same logic applies, even if the regulatory pressure does not. A one-day audit using freely available tools costs far less than a year of unnecessary cloud bills.
