Duplicate Images in Melbourne's Public Record: What Happens Next and the Key Decisions Ahead

Melbourne's public institutions are facing a reckoning over their digital image libraries. A growing number of councils, state agencies, and cultural organisations across Victoria have discovered that their online collections — used in everything from planning documents to community newsletters — contain significant volumes of duplicate or near-identical photographs, raising questions about archival integrity, storage costs, and whether the images actually reflect the city's diversity.

The issue matters now because Victoria's Digital Asset Management Policy, which the Department of Government Services has been progressively enforcing since early 2025, requires agencies to conduct full audits of digital holdings before the end of the 2026-27 financial year. For many organisations, that deadline is closer than their backlogs suggest it should be.

What the Audit Process Actually Looks Like

At the City of Melbourne, the audit work sits inside the broader Smart City Office program based at Council House 2 on Little Collins Street. Staff there are working through tens of thousands of catalogued assets, some dating back to digitisation drives in the early 2000s, looking for redundant files that inflate storage costs and create confusion when communications teams go looking for usable material.

The State Library Victoria on Swanston Street is navigating a parallel process for its Pictorial Collection, which holds more than 800,000 images. Librarians there have identified duplication as a particular problem in donated collections, where the same photograph sometimes entered the archive multiple times via different donors over different decades. The library's digitisation team has been using automated perceptual-hashing tools since late 2024 to flag likely duplicates for human review — a workflow that speeds up detection but still requires a specialist to make the final call on which version to keep and which to retire.

That human call is where cost and ethics converge. Keeping the highest-resolution version of an image seems obvious, but the lower-resolution duplicate sometimes carries richer metadata — a more precise location tag, a donor name, a date confirmed by a secondary source. Delete the wrong file and the institutional memory goes with it.

The Replacement Problem: Who Decides What Goes In?

Replacing retired duplicates with fresh material is not straightforward, either. Stock photography subscriptions through services used by Victorian government agencies can run to several thousand dollars annually per licence tier, and budget cycles inside local government often do not align with the moment an audit identifies a gap. Inner-north councils including Yarra City Council, which covers Collingwood, Fitzroy, and Richmond, have been trialling arrangements with community photographers to fill gaps with locally sourced material — an approach that is cheaper but requires its own rights-management framework.

The Victorian Multicultural Commission, headquartered in the CBD on Bourke Street, has separately flagged that duplicate-image audits present an opportunity, not just an administrative burden. Where stock libraries over-represent generic cityscapes or demographic groups that do not match local populations, replacement decisions can be made deliberately to improve representation. That argument has found some traction inside the Department of Premier and Cabinet's communications unit, which updated its visual identity guidelines in March 2026 to encourage agencies to document the rationale behind image selections.

Cost pressures are real. Cloud storage for government digital assets in Victoria is not free, and the Department of Government Services has indicated that agencies failing to reduce redundant holdings before the June 2027 deadline may face chargeback adjustments under the whole-of-government ICT cost-recovery framework introduced in the 2025-26 budget.

The decisions ahead are sequential. First, institutions need to complete the detection phase — knowing what duplicates they actually hold. Second, they need a clear retention policy that weighs resolution against metadata richness. Third, replacement sourcing needs a budget line confirmed before assets are retired, not after gaps appear. Organisations that treat the audit as a compliance checkbox rather than a content strategy question are likely to find themselves with holes in their visual archives at precisely the moment a grant application or a community campaign needs them filled. The June 2027 deadline is eleven months away. That sounds comfortable. It is not.
