Adelaide Tackles Duplicate Image Pollution Online — But Is It Keeping Pace With Rotterdam and Medellín?

Adelaide's cultural and technology organisations are confronting a growing administrative headache: duplicate images clogging digital asset management systems across the city's expanding creative and defence-tech sectors, with some institutions reporting that redundant files now account for a significant share of storage overhead. The problem is neither glamorous nor new, but it has sharpened into an operational priority as Lot Fourteen — the North Terrace innovation precinct housing space startups, defence contractors and creative agencies — has added dozens of new tenants since 2024.

The timing matters. South Australia's state government has poured sustained investment into digital infrastructure over the past three years, anchored by the AUKUS submarine program's documentation and visualisation requirements and the hydrogen jobs plan's public communications rollout. Both programs generate large volumes of photography, technical renders and promotional imagery. When those assets are duplicated across departments and agencies without proper deduplication protocols, the inefficiency compounds fast.

What Adelaide Institutions Are Actually Doing

The South Australian Museum on North Terrace and the Art Gallery of South Australia, which shares the same cultural boulevard, have both undertaken digital collection audits in the past 18 months. Neither institution has published detailed figures publicly, but the broader sector context is instructive. A 2024 report by the Digital Preservation Coalition found that cultural heritage organisations globally were dedicating between 12 and 18 percent of their digital storage budgets to managing or deleting redundant files — a figure that several Australian gallery administrators have cited in industry forums as roughly consistent with their own experience.

At Lot Fourteen, the Australian Space Agency — headquartered in the precinct since its 2020 establishment — works with imagery from partner agencies internationally, including renders and satellite photography that arrive in multiple resolutions and file formats. Without automated deduplication layered into asset pipelines, the same image can exist in six or eight versions across a shared server environment. Local digital asset management firm Keepthink, which works with clients in the Grenfell Street and Pirie Street commercial corridors, has told industry conferences that Adelaide's mid-tier creative agencies are increasingly asking for deduplication as a standalone service item rather than bundling it into broader IT contracts.

How Other Cities Are Handling It

Rotterdam and Medellín offer instructive comparisons. Rotterdam's municipal cultural sector, coordinating through the city's Digital City program, mandated a unified digital asset management platform across 14 publicly funded institutions in 2023. By early 2025, the city reported cutting redundant image storage by roughly 34 percent across those organisations, according to documentation published by the Rotterdam municipality. Medellín, which has aggressively positioned itself as Latin America's innovation city, embedded deduplication audits into its Ruta N technology corridor procurement requirements from 2022 onward, meaning any contractor awarded a digital communications contract must demonstrate compliance with asset hygiene standards before sign-off.

Adelaide has no equivalent citywide mandate yet. The state government's Digital Strategy, last updated in 2023, addresses open data and cybersecurity but does not set deduplication benchmarks for funded cultural or technology bodies. That gap puts the city behind Rotterdam in particular, where the policy mechanism is already proving its value at scale.

Singapore's National Heritage Board, another peer institution comparison for the South Australian Museum, completed a full deduplication sweep of its 1.2-million-image archive in late 2024 using AI-assisted tooling. The exercise took eight months and freed up storage equivalent to what the board had projected would cost SGD 180,000 to expand. Adelaide's institutions are watching that result closely.

For organisations operating out of Lot Fourteen or along the cultural precinct on North Terrace, practical next steps are fairly straightforward. Adopting a single digital asset management platform across a department — rather than allowing individual teams to maintain siloed folders — eliminates most duplication at the point of creation. Scheduling quarterly deduplication audits, rather than ad-hoc annual reviews, keeps the problem manageable. And building asset hygiene requirements into procurement contracts, the approach Medellín formalised in 2022, shifts the responsibility upstream to content creators and contractors rather than leaving clean-up to IT teams after the fact. The city has the institutional infrastructure to move quickly on this. Whether the policy framework catches up to the operational reality is a separate question entirely.
