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

Bendigo City Council's digital image library, used by departments ranging from tourism promotion to heritage planning, contains thousands of duplicate files, some mislabelled, others corrupted through successive system migrations dating back to at least 2014. The problem has now reached a point where a formal duplicate-image replacement program is underway, with Council's Information Management team working through an audit that began in the first quarter of 2026.

The timing matters. Bendigo Health's capital expansion on Lucan Street has generated substantial new photographic documentation requirements, and La Trobe University's Bendigo campus on Edwards Road has been collaborating with Council on a regional digital heritage initiative. Both institutions rely on accurate, deduplicated image records when preparing public communications, grant submissions, and planning overlays. A cluttered archive is not merely an administrative inconvenience, it creates real risk of the wrong image appearing in the wrong document, including those submitted to the Victorian Heritage Council.

How the Archive Got Into This State

The root cause is not neglect. It is a decade of incompatible software transitions. Council shifted from a legacy DAM, digital asset management, system to a cloud-hosted platform in 2019, and again to a newer environment in late 2022. Each migration carried forward not just original files but working copies, web-optimised derivatives, and thumbnail variants, none of them consistently tagged. Filenames were not standardised across departments, so an aerial photograph of View Street taken in 2017 might exist under four or five different names depending on which team originally uploaded it.

Regional arts funding added another layer. Programs administered through Creative Victoria required recipient organisations, including the Bendigo Art Gallery on View Street and smaller venues in the Hargreaves Street precinct, to submit photographic evidence of funded activities. Those images entered Council's system alongside operational photography, with no consistent metadata protocol separating grant-compliance material from general communications assets. Over successive years the categories blurred.

Aboriginal cultural heritage protection work compounded the sensitivity. Images captured during surveys connected to the Dja Dja Wurrung Clans Aboriginal Corporation's registered agreements require restricted handling. Ensuring those files are neither duplicated into publicly accessible folders nor accidentally stripped of their access controls is a legal obligation, not a preference. The audit has identified this as one of its three priority streams.

What the Replacement Program Actually Involves

The practical work of duplicate-image replacement involves two phases. The first is automated: software scans the archive for pixel-level matches and near-matches, flagging probable duplicates for human review. Council's team has been using this approach since February 2026, working through a library that internal estimates place at more than 180,000 individual files. The second phase is manual curation, a librarian or records officer reviews flagged pairs, determines which version carries the best metadata and highest resolution, retains that copy, and either deletes or archives the inferior duplicate.

For heritage overlays covering areas like the Golden Square neighbourhood and the Ironbark precinct near the former mine sites, accurate image provenance is directly relevant to planning decisions. A photograph miscatalogued by even a single year can misrepresent the state of a heritage facade at a legally significant point in time.

La Trobe University's involvement brings some institutional depth to the project. The Bendigo campus has postgraduate programs in information management and archival studies, and at least some of the audit work has been structured to provide practical placement experience for students, though the precise terms of that arrangement were not available at the time of publication.

Residents and community organisations who have submitted images to Council, through history projects, the Bendigo Easter Festival documentation archive, or neighbourhood planning consultations, can expect to receive communications in coming months asking them to confirm preferred versions of any material they originally provided. The Council's records team has indicated the audit is expected to reach completion before the end of the 2026 calendar year, clearing the way for a single unified archive with consistent tagging and access controls going forward.
