Duplicate Image Replacement: What Officials, Experts and Key Figures Are Saying

Melbourne's government agencies, cultural institutions and urban planners are under mounting pressure to clean up their digital archives, after audits across several Victorian public bodies found widespread duplication in image libraries used for planning applications, public communications and heritage documentation. The problem is not trivial. Duplicated images in official records have delayed development approvals, muddied heritage assessments and, in at least one case reviewed by The Daily Melbourne, caused a Stonnington Council planning panel to receive conflicting visual evidence for the same Prahran streetscape in a single submission.

The timing matters. Victoria's housing density reforms — pushed hard by the state Labor government since late 2024 — have dramatically increased the volume of planning applications flowing through local councils. Yarra, Maribyrnong and Melbourne City Council all reported spikes in digital documentation lodged through the state's SPEAR planning portal in the first half of 2026. When image libraries are bloated with duplicates, verification slows. Planners spend time cross-checking photographs that turn out to be identical files renamed and resubmitted, sometimes by different applicants referencing the same streetscape or heritage overlay zone.

What the Experts Are Pointing To

Digital asset management specialists and archivists working with Victorian institutions have been vocal about the structural causes. The issue is not carelessness — it is the absence of a centralised deduplication standard across the public sector. The Public Record Office Victoria, based in North Melbourne on Wreckyn Street, maintains standards for government recordkeeping, but its guidelines have not been updated to specifically address image hash-matching or metadata-based duplicate detection, a gap that practitioners in the field have flagged repeatedly at forums including the Records and Information Management Professionals Australasia conferences.

At the University of Melbourne's School of Computing and Information Systems in Parkville, researchers working on the ARC-funded FAIR Data project have argued since at least 2025 that Victorian government portals need automated perceptual hashing built into upload workflows — a technical fix that would flag near-identical images at the point of submission rather than after the fact. The approach is already used by the National Library of Australia's Trove platform for digitised newspaper images. Adopting something comparable for planning and heritage portals would not require significant capital expenditure; commercial tools capable of the task are available for under $20,000 annually for enterprise-level deployments.

Arts and cultural organisations are watching the debate closely. Creative Victoria, the state government's arts funding and development agency, manages image assets for hundreds of funded projects each year. Duplicate images in grant acquittal documentation have complicated auditing processes, according to sector insiders who requested anonymity because they were not authorised to speak publicly. The State Library Victoria on Swanston Street has separately begun a pilot project to deduplicate photographic holdings in its Pictures Collection, a body of work exceeding 800,000 items, some of which exist in multiple digitised copies across different collection management systems.

The Cost Question No One Wants to Answer

Who funds a sector-wide fix remains unresolved. The Victorian Government's Digital Strategy, last updated in March 2025, committed $12.4 million to improving data interoperability across agencies — but deduplication of image assets was not listed as a priority workstream. Advocates say that is a mistake, arguing that the downstream costs of duplicate records in planning delays alone likely exceed the price of prevention.

Melbourne City Council's Smart City Office, located within Council House 2 on Little Collins Street, confirmed it is reviewing its asset management workflows as part of a broader digital infrastructure audit due to report internally by September 2026. Other councils have not publicly committed to equivalent reviews.

For community members and architects lodging planning applications, the practical advice from planning consultants is straightforward: use consistent file-naming conventions tied to cadastral parcel numbers, strip metadata before resubmitting images from previous applications, and check SPEAR's own submission guidelines, last revised in January 2026, which now explicitly discourage uploading image files previously lodged for a different application on the same site. Whether councils will enforce that guidance consistently is the question practitioners are still waiting on.
