Bendigo Families Say Their Stories Are Being Erased: The Fight Over Duplicate Images in Cultural Records

Duplicate image replacement — the automated process of identifying and substituting repeated photographs in digital archives — has become a flashpoint in Bendigo's cultural heritage community, with families and local organisations saying the technology is doing more harm than good to records that can never be rebuilt.

The issue has sharpened considerably in recent months. Collecting institutions across regional Victoria have been under pressure to reduce digital storage costs and standardise catalogue holdings, and several have trialled automated deduplication software as a cost-cutting measure. In Bendigo, that pressure is landing on archives that hold some of the most detailed photographic records of Aboriginal country and colonial-era settlement in central Victoria.

What Gets Lost When a 'Duplicate' Disappears

At the Bendigo Regional Archives Centre on Pall Mall, volunteers and researchers have raised concerns about what happens when an algorithm flags two photographs as identical. In practice, images that appear the same to a machine can carry different contextual metadata — different annotations, different provenance notes, different community attributions — that matter enormously to descendant families and cultural heritage practitioners.

The Dja Dja Wurrung Clans Aboriginal Corporation, which holds a formal recognition agreement over country that encompasses much of the Bendigo region, has been working with collecting institutions for several years to ensure Aboriginal cultural material is handled according to community protocols rather than purely administrative efficiency rules. When automated tools make deletion decisions, those protocols can be bypassed entirely.

Community members who spoke to The Daily Bendigo — some of whom did not wish to be named because they feared jeopardising ongoing relationships with the institutions holding their family records — described the experience of discovering a photograph of a grandparent or great-grandparent had been removed as a duplicate as deeply distressing. Several said they had submitted formal requests to recover deleted files only to be told the originals were unrecoverable.

The Bendigo Art Gallery on View Street has not been directly implicated in the deduplication disputes, but gallery staff have acknowledged internally that the broader sector is grappling with the same tension between digital housekeeping and cultural responsibility. La Trobe University's Bendigo campus, which runs humanities and information management programs, has in recent semesters included case studies on exactly this kind of archival ethics question in its curriculum.

The Numbers Behind the Frustration

Australia's national framework for digital preservation, managed through the Australian Institute of Aboriginal and Torres Strait Islander Studies, requires that institutions seek community consent before altering or disposing of records relating to Aboriginal and Torres Strait Islander peoples. Under Victorian heritage legislation, certain categories of cultural material are subject to additional protections that predate any institutional digitisation policy.

Bendigo Health's capital expansion project — currently the largest construction program in the city's recent history — has prompted a parallel conversation about photographic records of the former hospital precinct on Lucan Street, where demolition and redevelopment have already changed the physical landscape beyond recognition. Historians associated with the Bendigo Historical Society, which holds more than 80,000 items in its collection at the former Mining Exchange building on View Street, say the deduplication question is not abstract: it is arriving at exactly the moment when construction activity is eliminating the physical sites that archival images document.

The cost of professional-grade digital preservation storage has fallen to roughly $30 to $50 per terabyte annually for institutional users, according to published pricing from Australian data centre providers as of mid-2026 — making the financial argument for aggressive deduplication far weaker than it was even five years ago.

For families waiting on answers, the practical next step is straightforward if not easy: submit a written request to the holding institution citing the specific item reference number, invoke the relevant provisions of the Public Records Act 1973 (Victoria) if the material is held by a public body, and — where Aboriginal cultural heritage is involved — contact the Dja Dja Wurrung Clans Aboriginal Corporation directly to request that the corporation advocate on the family's behalf. The Historical Society's research service on View Street operates Tuesday through Saturday and can assist with initial catalogue searches at no cost.
