By the Numbers: Ballarat's Duplicate Image Problem Is Costing Council Time and Money

The City of Ballarat is sitting on a digital asset library estimated to contain tens of thousands of images, and a significant portion of them are duplicates — the same photograph filed twice, three times, or more under different file names. The problem, long treated as a low-priority administrative headache, is now attracting attention because of what it costs to fix, and what it costs to ignore.

Regional councils across Victoria have been pushed in recent years to digitise historical records as part of broader public records compliance requirements under the Public Records Act 1973. For Ballarat, that pressure is acute. The city's gold-rush heritage, its Sturt Street streetscapes, the Sovereign Hill precinct, and the goldfields architecture of neighbourhoods like Ballarat East and Wendouree mean the photographic archive carries genuine cultural weight — and genuine financial value when it comes to tourism grant applications and heritage overlays.

What Duplication Actually Costs

Digital asset management research published by the international organisation AIIM — the Association for Intelligent Information Management — has found that knowledge workers spend an average of 30 to 40 percent of their time searching for information, with duplicate and mislabelled files among the top causes of that inefficiency. Applied to a council environment where multiple departments, including planning, tourism, communications and heritage, draw on the same image library, that figure compounds fast.

Ballarat Health Services' capital works documentation, for example, has involved extensive photographic records tied to its Sturt Street campus redevelopment planning. When images are duplicated across shared drives without consistent naming conventions, procurement staff and heritage consultants can end up sourcing the wrong version of a site photograph — triggering revision rounds that add days to project timelines.

The cost of a dedicated digital asset management (DAM) platform for a mid-sized regional council typically runs between $15,000 and $60,000 annually in licensing and implementation costs, depending on the vendor and the volume of assets under management. Ballarat's archive, drawing on contributions from Sovereign Hill, the Ballarat Heritage Office, and the council's own communications team, would sit at the higher end of that range by most industry benchmarks.

Sovereign Hill itself, which attracted more than 400,000 visitors in its pre-pandemic peak years and has rebuilt visitor numbers steadily since reopening fully in 2022, relies on photographic assets for grant applications to Tourism Victoria and for national marketing partnerships. Duplicate or unverified images in that pipeline create compliance risk when grant bodies require original, rights-cleared material.

The Fix — and Who Pays For It

The standard industry approach to duplicate image replacement involves a three-stage process: automated deduplication using hash-matching software, manual review by a records officer, and then a migration into a properly tagged DAM system with controlled vocabulary. Organisations that have completed this process report storage savings of between 20 and 45 percent of their original file volume, according to case studies published by the Australian Records Management Forum.

For Ballarat, the practical starting point would likely be the council's internal SharePoint environment and the separate archive maintained by the Ballarat Heritage Centre on Doveton Street North. Reconciling those two repositories alone — before touching the Sovereign Hill or health services holdings — would represent a substantial project requiring dedicated staff time over several months.

Victoria's Public Record Office has published guidance under its PROS 10/13 standard encouraging agencies to address digital duplication as part of scheduled disposal authorities. Councils that fail to meet those standards risk audit findings that can affect their standing in state grant rounds.

The practical advice for any ratepayer or community organisation that contributes images to council programs: supply files with embedded metadata, including date, location, and photographer credit, from the moment of upload. That single habit, if it became standard across the organisations operating along the Sturt Street and Lydiard Street heritage precincts, would slow the accumulation of duplicate records significantly — and reduce the bill that eventually lands on the council's IT budget.
