Ballarat's Public Art Registry Tackles Duplicate Image Problem After Heritage Audit Flags Gaps

Ballarat's cultural institutions spent the first week of July grappling with a practical but significant problem: hundreds of duplicate and incorrectly tagged images sitting across multiple public-facing digital databases, some of which have been live for years without cross-checking. The issue surfaced publicly this week after the City of Ballarat's ongoing heritage digitisation audit — part of a broader program tied to the Ballarat Heritage Strategy — identified overlapping records between the council's own asset register and the collection management systems used by the Art Gallery of Ballarat on Lydiard Street North.

The timing matters. Ballarat's identity as a gold heritage destination is directly linked to the quality and accuracy of its publicly accessible digital collections. Sovereign Hill, Visit Ballarat, and the Art Gallery of Ballarat collectively draw on shared image libraries to support tourism marketing, grant acquittals, and educational programs. When duplicate or misidentified images circulate in those systems, the downstream consequences range from embarrassing reprints in visitor guides to errors in grant-funded publications that require corrective action with funders including Creative Victoria.

What the Audit Found This Week

The audit, conducted by council staff in collaboration with the Ballarat Heritage Advisory Committee, identified more than 340 duplicate image records across three separate digital repositories as of Thursday. A further subset — the exact number is still being confirmed — involved images where the metadata attributed works to the wrong decade or, in some cases, the wrong location entirely. Several images of the Eureka Centre site on Stawell Street had been catalogued under Sovereign Hill's Magpie Street precinct, according to information provided at this week's committee briefing.

The issue is not unique to Ballarat. The State Library of Victoria ran a similar deduplication project across its digital archive in 2024, ultimately removing or consolidating more than 12,000 catalogue entries. But for a regional institution operating with a fraction of the staffing, the manual workload is considerable. The Art Gallery of Ballarat, which holds a permanent collection of more than 6,000 works, confirmed this week that it had begun a line-by-line review of its online catalogue after council staff flagged the cross-database discrepancies.

For Sovereign Hill, which receives state tourism grant funding and maintains its own photographic archive of the open-air museum's 25-hectare site, the duplicate image problem has practical consequences for licensing. When the same image appears under two different rights classifications in separate systems, neither licensee nor user can be certain which record governs permitted use — a complication that has stalled at least one planned promotional project, according to the agenda notes from this week's Ballarat Tourism and Events Committee meeting.

The Fix and What Comes Next

The City of Ballarat's library and cultural services team is coordinating a consolidated response. A working group involving the Art Gallery of Ballarat, Ballarat Libraries — which operates the digital local history collection through the Ballarat Mechanics' Institute on Sturt Street — and Sovereign Hill's curatorial staff held its first joint session on Wednesday. The group is targeting a reconciled, cross-referenced image register by the end of the third quarter of this financial year, which means a September deadline.

The cost of the remediation work has not yet been formally budgeted as a standalone item. Council's existing heritage digitisation allocation for 2025–26 was set at $180,000, covering both scanning of physical records and database maintenance. Officers are expected to advise councillors at the next ordinary council meeting whether additional resources are needed to complete the deduplication before September.

For residents and researchers who use the council's online heritage portal or the gallery's public collection browser, the immediate advice is straightforward: cross-reference any image sourced from Ballarat's public databases against the Ballarat Heritage Advisory Committee's published holdings list before using it in publications or grant applications. The committee updates that list quarterly, with the next update due in August. Until the consolidated register is live, the Mechanics' Institute's reference desk on Sturt Street remains the most reliable single point of contact for image rights queries.
