The problem did not happen overnight. Ballarat's municipal image library — a sprawling digital collection maintained across the City of Ballarat's communications directorate, the Art Gallery of Ballarat on Lydiard Street North, and the Ballarat Heritage Office — now holds an estimated tens of thousands of duplicate image files, the product of more than fifteen years of disconnected digitisation efforts. Staff responsible for the collection have been working through a remediation program since late 2024, but the backlog remains substantial.
The timing matters. Regional Victoria's tourism and cultural funding environment is more competitive than it has been in years. Sovereign Hill, which drew record visitor numbers in the post-pandemic rebound, depends heavily on licensing high-quality heritage imagery for promotional campaigns, grant acquittals and media liaison. When duplicates clog a shared asset library, staff waste time locating authoritative versions of photographs, risk publishing outdated or watermarked copies, and occasionally submit the wrong file to funding bodies — a problem that carries real administrative consequences when acquittals go to bodies like Regional Arts Victoria or Creative Victoria.
A Patchwork of Digitisation Projects
Ballarat's image duplication problem traces directly to the digitisation boom of the early 2010s. Between 2011 and 2018, at least four separate grant-funded scanning projects ran across the city, each using different naming conventions, different metadata standards and, critically, different software platforms. The Ballarat Heritage Office ran a Victorian Heritage Council-funded project cataloguing goldfields-era photography. The Art Gallery of Ballarat undertook its own collection digitisation under a separate Museums Victoria partnership. The council's communications team built a Photoshelter-based asset library for media and marketing use. Sovereign Hill maintained its own internal archive on a legacy system.
None of these repositories talked to each other. The same photograph of the Sturt Street gardens taken in 1978, for example, might exist in four separate systems under four different file names, with different crop ratios and inconsistent caption information. When staff changed roles or left the organisations entirely, institutional knowledge about which version was the master copy often left with them.
The Ballarat Central library branch on Doveton Street became a partial clearinghouse during the 2019 Local History digitisation push, but that project added a fifth repository rather than consolidating the existing four. By 2022, internal audits were flagging the duplication issue as a practical burden, though dedicated funding to address it was not allocated until the 2024-25 budget cycle.
What the Remediation Work Actually Involves
The current remediation program is not simply deleting obvious copies. Staff are using perceptual hashing software to identify near-duplicate images — photographs that are technically different files but visually identical or near-identical — and then manually reviewing flagged pairs before any deletion. That manual review step is slow. A collection of roughly 80,000 images can take a small team the better part of a year to process, particularly when provenance questions require consulting original accession records.
The work intersects with a broader push across regional Victorian councils to consolidate digital asset management ahead of the state government's Creative Industries Strategy review, expected to shape grant criteria from 2027 onward. Organisations that cannot demonstrate clean, well-catalogued digital collections may find it harder to satisfy acquittal requirements for future rounds of funding under programs administered through Creative Victoria.
For heritage institutions on Lydiard Street, the practical stakes are straightforward: a photograph licensed incorrectly because staff grabbed a duplicate with the wrong rights clearance attached can trigger a formal complaint from a rights holder and, in some cases, a demand for retrospective licensing fees. That risk increases as the collection grows.
The remediation team's current target is to clear the highest-priority tourism and media imagery — roughly 12,000 files — before the end of calendar year 2026, in time for the summer promotional season. Longer-term, the goal is a single unified platform, though procurement for that system has not yet begun. Anyone with questions about image rights or access to the heritage collection can contact the Ballarat Heritage Office directly through the City of Ballarat's main Doveton Street offices.
