Melbourne's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

Melbourne's public institutions are sitting on a growing crisis buried inside their own hard drives. Duplicate images — identical or near-identical photographs, scans and digital artworks stored multiple times across separate servers — have quietly consumed tens of thousands of gigabytes of storage across the City of Melbourne's digital collections, the State Library Victoria and several council-run community arts programs. The question now isn't whether to fix it. The question is who decides how, who pays, and which images get axed when the duplicates are finally purged.

The issue has sharpened in 2026 for a specific reason: the Victorian Government's Digital Asset Management Review, which launched in March, is due to deliver its preliminary findings to the Department of Government Services by late August. Whatever framework it recommends will flow directly into procurement decisions at agencies across the state. That makes the next eight weeks a genuine inflection point — organisations that haven't audited their image libraries before the review lands risk having external standards imposed on them rather than shaping the process themselves.

What's at Stake on Swanston Street and Beyond

At the State Library Victoria on Swanston Street, the La Trobe Picture Collection holds more than 800,000 images in physical and digital form. Digitisation projects running since 2018 have introduced duplication at scale: a single photographic plate scanned at multiple resolutions for different access tiers can generate four or five discrete files, each catalogued separately. Multiply that across thousands of items and the redundancy problem compounds fast.

The City of Melbourne's Creative Programs office, which administers the Arts House venue in North Melbourne and several digital storytelling grants, has faced similar pressure. Grant recipients submitting final project documentation are routinely required to hand over image assets, but there is no unified deduplication standard applied before those files enter the council's archive. A spokesperson position on this issue remains unfilled following a restructure in February — meaning no single officer currently owns the problem.

Meanwhile, the Docklands-based digital preservation consultancy sector — several firms operate out of the NewQuay precinct — has seen a noticeable uptick in inquiries from local government clients since January. Deduplication software licences for mid-sized institutional collections typically run between $12,000 and $40,000 annually, depending on collection size and the level of AI-assisted matching required. For smaller councils in Melbourne's inner north and west, that price point is not trivial against already stretched IT budgets.

The Decisions That Can't Be Deferred

Three choices will define how this plays out. First, institutions must decide whether to adopt a centralised deduplication platform shared across agencies — a model the Victorian Government's Shared Services framework theoretically supports — or manage the process in-house. Centralisation is cheaper per institution but requires agreement on metadata standards that don't currently exist in a consistent form across Melbourne's public sector.

Second, curators and archivists will need to establish which file version survives when duplicates are identified. That is not a technical question. It is an editorial one. A photograph scanned at 300 DPI for research access and again at 72 DPI for web publication has different cultural value in each form. Deleting the lower-resolution version without a policy rationale could compromise public accessibility commitments under Victoria's Public Records Act 1973.

Third, there is the question of staff capability. The Australian Library and Information Association has flagged digital preservation skills as a workforce gap nationally. Institutions in Carlton, Fitzroy and the CBD that rely on a handful of specialist staff to manage legacy systems are acutely exposed if those staff leave before institutional knowledge is documented.

The August deadline for the Digital Asset Management Review is the nearest fixed point on the calendar. Organisations that submit formal input before then — the public consultation window closes July 25 — have the clearest opportunity to influence the outcome. After that, expect the framework to move quickly into a pilot phase, almost certainly involving two or three larger Victorian agencies before any rollout to councils. The window to shape the rules, rather than simply receive them, is closing.
