How Melbourne's Public Institutions Ended Up With a Duplicate Image Problem — and Why Fixing It Took This Long

Melbourne's publicly funded cultural and government bodies are sitting on digital image archives bloated by years of duplicate uploads, redundant file versions and untracked visual assets — a problem that has quietly compounded since councils and agencies began digitising their collections in earnest around 2014. The cost of storing, licensing and managing those duplicated files has become significant enough that several organisations are now midway through formal remediation programs.

The issue matters now because the Victorian Government's broader digital transformation agenda, which accelerated after the 2022 Digital Strategy rollout, has forced agencies to audit what they actually hold. When auditors go looking, the duplicates are everywhere. A single heritage photograph of Flinders Lane or the Yarra River precinct might exist in twelve slightly different crops, resolutions and filenames across multiple departmental servers — each logged as a separate asset, each potentially carrying a separate licensing record.

How the Archives Got This Way

The duplication problem has a clear paper trail. Between roughly 2015 and 2021, institutions including the City of Melbourne's online civic portal and the State Library Victoria's digital collections expanded their upload workflows faster than their governance frameworks could keep pace. Staff turnover was high. Naming conventions were inconsistent. When organisations migrated between content management systems — a process the State Library undertook in stages between 2018 and 2020 — assets were frequently re-ingested without cross-referencing what already existed. The result was layered redundancy baked into the foundation of collections that now number in the hundreds of thousands of files.

Commercial pressure made things worse. Tourism and event bodies, including those managing visual assets for precincts like Federation Square and the Melbourne Arts Precinct on St Kilda Road, often received image submissions from multiple contractors shooting the same events. Without a centralised digital asset management system enforcing deduplication at the point of upload, the same photograph of a New Year's Eve crowd or a Swanston Street installation might enter the archive from three different agencies on three different dates, tagged differently each time.

Cloud storage costs, which have climbed steadily, have given finance departments a new argument for action. Industry benchmarks from the International Digital Preservation Coalition suggest that unmanaged duplication in mid-sized institutional archives can inflate storage overheads by 20 to 40 percent — a figure that lands differently when agencies are being asked to account for every line of expenditure under post-pandemic budget scrutiny.

What Remediation Actually Looks Like

The practical response has been uneven. The City of Melbourne began a structured digital asset review in late 2024, part of a broader records management overhaul tied to its Smart City program. The State Library Victoria has been piloting perceptual hashing tools — software that identifies visually similar images even when filenames differ — across a subset of its Flickr Commons contributions. Neither organisation has publicly announced completion dates for full deduplication.

Smaller councils in the inner suburbs, including Yarra City Council based in Richmond and the City of Port Phillip covering South Melbourne and St Kilda, face the same structural problem with fewer dedicated digital staff to address it. For them, the realistic path is procurement of shared-service tools rather than bespoke solutions built in-house.

For organisations still at the beginning of this process, the practical steps are well-established if unglamorous: establish a single source-of-truth repository before accepting new uploads, apply consistent file-naming standards tied to date and event, and run perceptual hash comparisons against existing stock before ingesting any new batch. The technology to do this has existed for years. The organisational will to enforce it is what took time to arrive — and what, in Melbourne's case, a combination of budget pressure and the state's digital transformation agenda has finally supplied.
