Bendigo's Digital Archives Get a Boost as Duplicate Image Problem Finally Gets Addressed This Week

Bendigo's cultural institutions have spent years wrestling with a mundane but costly problem: duplicate images buried deep inside digital archives, eating up server space, confusing researchers, and slowing down public access to the region's visual history. This week, that problem got serious attention.

The City of Greater Bendigo confirmed it is partway through a staged rollout of deduplication protocols across its digital holdings, a process that affects collections held at the Bendigo Regional Archives Centre on Pall Mall and the reference library at the Bendigo Library on Hargreaves Street. The work involves auditing image files stored across multiple platforms and flagging redundant copies for removal or consolidation. Archivists are using perceptual hashing software — tools that identify near-identical images even when file names differ — to work through backlogs that have built up over more than a decade of digitisation grants and ad hoc scanning projects.

Why now? Digital storage is not free, and for regionally based organisations working with constrained budgets, the accumulation of duplicate files has real dollar costs. Beyond storage fees, the practical consequence is that researchers — whether genealogists working through Goldfields-era photographs or curators at the Bendigo Art Gallery preparing exhibitions — waste time sifting through identical or near-identical images to find the best-quality version of a single item.

Local Collections Feeling the Pressure

The Bendigo Art Gallery on View Street holds one of the largest regional public art collections in Victoria, and its digital catalogue has grown substantially since a major digitisation push in the early 2010s. Gallery staff have previously described managing digital assets as an ongoing operational challenge, though the institution has not publicly quantified the scale of duplication in its holdings. Separately, the Bendigo Historical Society, based in the old former Mining Exchange precinct, has been digitising photographic collections for years through successive state and federal grants, including programs administered through Public Record Office Victoria.

La Trobe University's Bendigo campus on Edwards Road also maintains digital research repositories, and library staff there have been working through similar issues as part of a broader university-wide data governance initiative. Regional campuses often inherit legacy systems that were set up independently of metropolitan infrastructure, which can compound duplication problems over time.

The current push in Bendigo sits within a wider Victorian context. The Public Record Office Victoria updated its digital recordkeeping standards in 2023, placing new obligations on local government and affiliated cultural bodies to manage digital assets more systematically. Councils that fall behind on compliance face audit risk. Greater Bendigo's 2025–26 budget allocated funding toward digital records management, though the council has not publicly specified a dollar figure tied solely to the image deduplication component of that work.

What Comes Next for Users and Researchers

For the public, the immediate effect of this week's progress should become visible over the coming months. Researchers accessing the Bendigo Regional Archives Centre — which handles walk-in requests Tuesday through Friday from 10am to 4pm — may find that online catalogue searches return cleaner, less cluttered results as redundant entries are removed. The Hargreaves Street library's local studies collection, which includes digitised copies of the Bendigo Advertiser going back to the 19th century, is also part of the review.

Anyone with collections donated to local institutions should be aware that the deduplication process is focused on digital files, not physical originals. No photographs or documents are being disposed of — the work is strictly about cleaning up electronic copies. Families or community groups who have previously donated items can contact the Bendigo Regional Archives Centre directly to check the status of their materials.

The timeline for completing the full audit has not been publicly confirmed, but archivists involved in the project have indicated the bulk of the high-priority collections should be processed before the end of the 2026 calendar year. For an institution whose photographic records stretch back to the gold rush era, getting the digital house in order is long overdue work.
