How Melbourne's Public Image Archive Ended Up Full of Duplicates — and What's Being Done to Fix It

Victoria's state government agencies are sitting on a sprawling mess of duplicate digital images — misfiled photographs, redundant scans, and mismatched assets spread across at least a dozen departmental databases — and the push to clean them up is now accelerating after a 2025 audit flagged the problem as a material risk to public record-keeping.

The issue matters right now because several major Victorian infrastructure and housing projects are generating fresh waves of digital documentation. With the state government's Housing Statement density reforms rolling out across suburbs like Broadmeadows and Footscray, planning departments are processing thousands of site photographs, heritage assessments, and architectural renders each month. When a duplicate image gets attached to the wrong planning file, the downstream consequences range from minor administrative delay to genuine legal ambiguity about what a site looked like before works began.

How the Backlog Built Up

The roots of the problem stretch back to the early 2010s, when Victorian agencies began migrating from paper-based and CD-archive systems to networked digital asset management platforms. The transitions were rarely clean. Staff across agencies like the Department of Transport and Planning and the Department of Energy, Environment and Climate Action uploaded files using inconsistent naming conventions — some by date, some by project code, some by suburb, and some with no convention at all. A photograph of a site on Nicholson Street in Fitzroy could end up stored under three different file names depending on who uploaded it and when.

By 2018, the Victorian Auditor-General's Office had noted in separate performance audits that digital records management across multiple agencies showed signs of structural disorganisation, though the specific scale of duplicate imagery was not quantified at that stage. The problem compounded during the COVID-19 pandemic years, when remote working led staff to create local copies of images on personal drives, then re-upload them to shared servers months later without checking for existing files.

The City of Melbourne's own digital asset library, which covers photography from public events held at Federation Square, the Royal Exhibition Building, and dozens of smaller venues, had by early 2025 accumulated an estimated 40,000 near-duplicate image pairs, according to internal figures cited in a procurement tender published on the Victorian Government's Tenders and Contracts website in March 2025. That tender, seeking a specialist digital asset management vendor, listed duplicate image resolution as the primary deliverable.

The Fix: Deduplication Software and New Protocols

The practical solution now being rolled out across several agencies involves automated deduplication tools that compare images using perceptual hash algorithms — software that can identify two photographs as functionally identical even if they have different file names, sizes, or metadata timestamps. The State Library of Victoria, which manages its own photographic collections separately from operational government systems, trialled one such tool across its digitised lantern slide collection at its La Trobe Street premises in late 2024.

For the broader public sector, the Victorian Government's Chief Data Officer unit, operating under the Department of Government Services, issued updated guidance in February 2026 requiring agencies to conduct a baseline duplicate audit before any new digital asset management contract is signed. That guidance applies to departments but not, notably, to statutory authorities, which has left organisations like VicRoads and Suburban Rail Loop Authority on a different compliance timeline.

The practical advice for anyone dealing with Victorian government image archives in a professional capacity — heritage consultants working on Fitzroy or Port Melbourne projects, journalists filing FOI requests that include photo attachments, architects submitting planning applications in the Hoddle Grid — is to reference file metadata and request original upload logs rather than relying solely on file names. Agencies are now required to provide a provenance record alongside any image released under FOI, a rule that took effect on 1 April 2026. The deduplication process itself is expected to take the better part of two more years to complete across all affected agencies, meaning the messy middle period is still very much underway.
