Bendigo's Cultural Institutions Push Back on Duplicate Image Problem: What the Experts Are Saying

A quiet but consequential problem has surfaced in Bendigo's cultural sector: the unchecked proliferation of duplicate digital images across institutional archives is undermining collection integrity, wasting storage resources and, in some cases, presenting the wrong version of a historical photograph or artwork to the public. Archivists, collection managers and digital preservation specialists are now calling for coordinated action.

The issue has sharpened in recent months as several institutions — including the Bendigo Art Gallery on View Street and the Bendigo Regional Archives Centre — have accelerated digitisation programs tied to state-funded heritage grants. That push, while welcome, has exposed a structural gap: without standardised deduplication protocols, the same image can enter a database dozens of times under different file names, metadata tags or scan resolutions, with no automatic flag to alert staff.

Why It Matters Now

Digital collection work has moved fast across regional Victoria since 2023, when Creative Victoria expanded its Regional Collections Digitisation Fund. Institutions that previously managed a few hundred digital assets are now handling tens of thousands. Bendigo Health, which maintains historical photographic records of the Base Hospital on Lucan Street dating back to the late 19th century, is among the organisations navigating this scale-up. The hospital's heritage collection, managed in partnership with the Bendigo Regional Archives Centre, includes photographic prints, glass plate negatives and administrative documents that require careful version control during digitisation — precisely the environment where duplicates multiply.

Specialists in the field point to several root causes. Batch scanning at different resolutions for different output purposes — web display versus archival preservation — routinely generates multiple files from a single original. Staff turnover means new operators re-scan items that were already processed. And file-naming conventions, when they exist at all, vary between departments and across funding cycles.

The consequences are more than administrative. When a duplicate image with inferior metadata or a cropped composition gets indexed first, it can become the version that researchers, journalists and the public encounter. For collections tied to Aboriginal cultural heritage — a sensitive and legally significant area given Victoria's Aboriginal Heritage Act 2006 — a mislabelled or duplicated image raises concerns that go well beyond storage efficiency.

What Institutions and Specialists Are Recommending

Collection management professionals working across the region broadly agree on a set of practical responses, even if no single authority has yet mandated them. The first is the adoption of perceptual hashing tools — software that compares images based on visual content rather than file name or size, and can identify near-identical duplicates even when they have been resaved or slightly cropped. Several public libraries in Victoria piloted this approach during 2024 and 2025, reporting meaningful reductions in redundant files within the first six months.

The second recommendation is the development of shared metadata standards across Bendigo's cultural institutions. La Trobe University's Bendigo campus on Edwards Road, which houses the university's library collections and supports research partnerships with local heritage bodies, has been identified as a logical convening point for cross-institutional dialogue. A coordinated framework, rather than each institution developing its own, would reduce duplication at the point of data entry rather than relying on retrospective clean-up.

Third, specialists are urging institutions to build deduplication audits into their digitisation grant reporting requirements — rather than treating them as a discretionary add-on. Given that Regional Collections Digitisation Fund grants typically run on 12 to 18 month cycles, embedding this step before final acquittals would create a natural accountability mechanism.

For Bendigo residents and researchers who use these collections — whether tracing family history at the Goldfields Library on Hargreaves Street or accessing historical imagery for heritage planning purposes — the practical upshot is straightforward: always check whether alternative versions of an image exist in a collection before relying on the first result. Collection managers at the Bendigo Art Gallery have indicated they welcome direct queries about image provenance and can often identify when a listed file is a secondary copy.

The broader conversation is expected to gain momentum at the Museums Australia (Victoria) regional forum later this year, where duplicate image management is likely to appear on the agenda for the first time as a standalone topic rather than a footnote under general digitisation practice.
