Melbourne's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

A quiet but consequential reckoning is underway across Melbourne's public institutions and property sector. Duplicate digital images — redundant, untagged and eating up storage and staff time — have accumulated to a point where several organisations are being forced to act. The question now is not whether to clean house, but how, and who bears the cost.

The timing matters. Victoria's state government has been pushing councils toward digital-first record-keeping under the Public Records Act, and the deadline pressure from the Public Record Office Victoria for updated digital asset policies has nudged bodies like the City of Melbourne and Yarra City Council to audit their image libraries more aggressively than at any point since the early 2010s. Sitting on duplicate records is no longer just an IT headache — it carries compliance risk.

The Scale of the Problem Locally

At the City of Melbourne's offices on Little Collins Street, internal reviews have identified planning, events and communications archives as the most clogged. Events like the Moomba festival and the Melbourne International Arts Festival generate thousands of images annually, many filed multiple times across different departments. The State Library of Victoria on Swanston Street faces a parallel issue with digitised historical collections, where scanning programs from the 2010s produced near-identical files that were ingested into the catalogue without deduplication checks.

The Victorian Government's Digital Victoria program, which has guided agency IT investment since its relaunch in 2022, recommends automated deduplication tools as part of cloud migration projects. But adoption has been uneven. Smaller councils in Melbourne's inner north and west — including Moonee Valley and Merri-bek — have publicly acknowledged they are still working through legacy on-premises storage systems that predate modern metadata standards.

Property is another flashpoint. In Melbourne's real estate sector, where platforms like Domain and REA Group list hundreds of thousands of properties, duplicate listing images are a persistent commercial and legal irritant. Real estate agencies operating out of precincts like South Yarra and Carlton frequently re-list properties with image sets recycled from previous campaigns, creating confusion for buyers and potential liability under Australian Consumer Law. The Real Estate Institute of Victoria has flagged image attribution and duplication as a training priority for its 2026 professional development calendar.

Who Decides, and When

Three distinct decisions now sit on the table for Melbourne's institutions. First, whether to invest in automated AI-assisted deduplication software — tools that can cost anywhere from a few thousand dollars for a small council to more than $200,000 for an enterprise-scale implementation. Second, whether to establish shared standards across Victorian local government, rather than leaving each council to procure its own solution independently. Third, and most politically charged, who owns the original image when a duplicate is removed and multiple departments claim the source file.

The Andrews-era reform of the Victorian Government's whole-of-government ICT procurement, which standardised cloud contracts across roughly 80 agencies, gives the current state government a mechanism to push a coordinated approach. Whether the Jacinta Allan government moves to mandate deduplication protocols — or leaves it to individual agencies — will likely become clear when the Digital Victoria roadmap is updated in the second half of 2026.

For councils, the practical path forward involves three near-term steps: completing a storage audit before the end of the 2026-27 financial year, nominating a single digital records officer with authority to approve deletions, and piloting deduplication tools on a contained archive — event photography being the obvious starting point given its volume and low legal sensitivity. Yarra City Council's library services team has already begun a pilot along these lines, focusing on its Fitzroy and Richmond branch digitisation projects.

The costs of inaction are not abstract. Cloud storage is not free, staff time spent managing bloated libraries is not recoverable, and public trust in institutions that cannot reliably manage their own records erodes steadily. The next six months will test whether Melbourne's public sector treats this as the infrastructure problem it is, or defers it once again to the bottom of the budget queue.
