How Melbourne's Public Art Stockpile Ended Up Full of Duplicates, and What's Being Done About It

The City of Melbourne is working through a systematic audit of its public art and heritage image database after years of duplicate entries, mismatched photographs and redundant digital files quietly accumulated across council-managed collections, a problem now being addressed through a dedicated duplicate-image replacement program that archivists and collection managers say has been a long time coming.

The issue matters now for a specific reason: Melbourne's cultural infrastructure has expanded sharply over the past decade. The council's public art collection has grown to include works across dozens of inner-city laneways, parks and civic buildings, from Hosier Lane in the CBD to the Birrarung Marr riverside precinct, while the digital cataloguing systems meant to keep pace with that growth were patched together from at least three separate legacy platforms, none of which spoke cleanly to each other. The result was predictable: identical images filed under different asset numbers, artworks photographed multiple times by different contractors with no deduplication check, and in some cases the wrong photograph sitting against the right artwork record for years.

How the Duplicates Piled Up

The roots of the problem stretch back to the early 2010s, when Melbourne City Council began digitising its physical collection records in earnest. At the time, different units, public art, heritage planning and parks, each maintained their own databases. A mural commissioned for a Fitzroy streetscape might be photographed by a council heritage officer, again by a public art coordinator and a third time by a contractor producing condition reports. Without a centralised intake system with automatic hash-matching or metadata cross-referencing, those three files entered the archive as three separate records.

Creative Victoria, the state government's arts funding and policy agency, flagged similar systemic issues in a 2022 review of how Victorian cultural institutions managed digital assets. The review, which covered organisations receiving state funding, found that collection management software licences across the sector were fragmented and that many smaller organisations lacked the technical capacity to run deduplication checks. That state-level finding gave councils including Melbourne additional impetus to look inward at their own holdings.

The National Gallery of Victoria on St Kilda Road, which manages one of the largest art collections in the Southern Hemisphere, has run its own duplicate-image remediation work as part of broader database migration projects. While the NGV operates at a different scale and with different resources than local council collections, its public documentation of that process, including guidance published through the Collections Australia Network, has served as a practical reference point for smaller teams trying to design their own workflows.

What the Audit Involves, and What Comes Next

At the council level, the current program involves running existing image files through matching software to flag near-identical entries, then routing flagged items to a human reviewer, typically a collections officer, who confirms whether files are true duplicates, variant condition shots of the same work, or genuinely distinct records that share visual similarities. Where a duplicate is confirmed, the lower-quality or less accurately described file is marked for replacement with the authoritative version, and metadata is updated to reflect the correct provenance and location data.

The practical stakes are not trivial. Melbourne's public art database feeds into publicly accessible platforms including the council's own open data portal and third-party tourism and heritage apps that pull from council records. A duplicated or wrongly attributed image in the back-end database can surface as a factual error in those public-facing tools, an artwork listed at the wrong address, or a photograph of a Federation Square installation filed under a Docklands project.

Collection managers involved in similar programs at institutions such as the Melbourne Museum at Carlton Gardens have noted that the audit phase typically takes longer than the replacement phase. Identifying what is wrong is harder than fixing it. For a council managing hundreds of discrete public artworks across the CBD and inner suburbs, the audit component alone is expected to run through the remainder of 2026 before systematic replacement of flagged image files can be completed at scale.

For residents and researchers who rely on public collection data, the practical advice is straightforward: treat any digitally sourced image attribution from council or state cultural databases as provisional until the remediation program is complete, and cross-reference against on-the-ground records or the holding institution directly where accuracy matters.
