Bendigo Leads Regional Australia in Tackling Duplicate Public Art Images — But Global Peers Are Moving Faster

Bendigo's public institutions hold thousands of digitised images across municipal registers, cultural heritage databases, and arts program archives — and a significant portion of them are duplicates. The City of Greater Bendigo, through its ongoing digital asset review, has been working to identify and replace redundant image records that clog catalogues, distort search results, and in some cases misrepresent the provenance of Aboriginal cultural material.

The problem matters now for reasons that go beyond tidiness. Across Victoria's regional centres, digitisation grants tied to the state government's Creative Victoria funding rounds have pushed councils and arts organisations to upload large volumes of material quickly. Volume without verification creates duplication. In heritage-sensitive contexts — particularly for collections involving Dja Dja Wurrung cultural objects and sites documented in the Bendigo region — a duplicated or mislabelled image is not just a clerical error. It can compromise the integrity of land and cultural heritage assessments.

What Bendigo Is Actually Doing

The Bendigo Art Gallery on View Street, which holds one of the largest regional public collections in Australia, began a structured deduplication process as part of its 2024–2026 collection management plan. The gallery's digital catalogue, which spans tens of thousands of records, had accumulated duplicate image entries through successive migration projects. Staff have been working through those records using metadata comparison tools, prioritising works with public-facing catalogue entries.

La Trobe University's Bendigo campus, on Edwards Road, has contributed academic expertise to the broader conversation. The university's information studies and digital humanities staff have been involved in advising regional councils on best-practice image metadata standards, drawing on frameworks developed by the Digital Public Library of America and the Europeana network in Europe. Neither institution has published specific deduplication figures for their Bendigo holdings as of this week, but the work is ongoing.

The Bendigo Library on Hargreaves Street, operated by the City of Greater Bendigo, also maintains digitised local history collections. That collection includes photographic records of Bendigo's goldfield-era streetscapes and portraits, many of which were scanned at different resolutions across multiple projects dating back to at least 2008. Duplicate entries in those records are a known issue that library staff have flagged in internal reviews.

How Other Cities Are Handling It

Malmö, in southern Sweden, completed a city-wide public image deduplication project in 2023 across its municipal cultural institutions, using an AI-assisted matching system integrated into its existing collections management software. The project reportedly reduced redundant entries in Malmö's public digital archive by roughly 34 percent, according to documentation published by Malmö Museum. That is the kind of benchmark Australian regional cities are now measuring themselves against.

Medellín, Colombia, took a different approach through its Red de Bibliotecas Públicas network — crowd-sourced verification combined with automated hash-matching, a process that identified duplicate image records across 47 library branches. The cost was lower than proprietary software solutions, and the model has since been cited in UNESCO digital heritage guidance published in 2024.

Bendigo is not as far along as either city. The audit work here remains largely manual, resource-constrained, and distributed across agencies that do not yet share a unified collections platform. That is a structural gap that similar-sized regional cities in Germany — Freiburg im Breisgau, for example, with a comparable population of around 230,000 — addressed through a federated collections agreement that pooled deduplication costs across municipal, university, and arts institution libraries.

For Bendigo residents and researchers using public image archives, the practical implication is straightforward: catalogue searches, particularly for goldfields history and local Aboriginal cultural heritage records, will continue to return imprecise results until the deduplication work advances. Organisations relying on those archives for planning submissions, heritage assessments, or arts grant applications should verify image records directly with the holding institution rather than relying solely on online catalogue results. The Bendigo Art Gallery's collections team can be contacted directly through the gallery's View Street premises for verification requests.
