Hunter region councils and cultural institutions are sitting on tens of thousands of duplicate digital images across public-facing platforms, internal servers, and heritage archives — a problem that has quietly ballooned in cost and complexity since the pandemic-era rush to digitise everything. The question now is whether Newcastle is ahead of the curve or falling behind cities that have already started fixing it.
The issue landed squarely on the agenda this year partly because of broader pressure on local government budgets. Cloud storage is not cheap. Redundant image files — identical or near-identical photographs duplicated across multiple systems during bulk uploads — inflate storage bills, slow down content management systems, and create compliance headaches under NSW State Records legislation, which requires agencies to manage records systematically under the State Records Act 1998.
What Newcastle Is Actually Doing
Newcastle City Council has been rolling out upgrades to its digital asset management infrastructure since late 2024, a process tied in part to the broader Smart City Strategy the council adopted in 2023. The Hunter-based team managing the council's corporate image library — which covers everything from planning documents to marketing photography of Honeysuckle precinct and Nobby's Beach — has been working through a deduplication audit, according to council planning documents tabled earlier this year.
The University of Newcastle's Digital Humanities Lab, based at the Callaghan campus, has been separately grappling with the same problem across its cultural heritage digitisation projects. The lab has partnered with the Newcastle Region Library on several archive initiatives covering the coalfields and the former BHP steelworks at Mayfield, producing thousands of scanned images, some of which ended up duplicated across the university's research repository and the library's own public collections portal. Library management has flagged the deduplication work as part of its 2025–26 operational priorities.
The Hunter-based not-for-profit Renew Newcastle, which has run creative reactivation programs in the CBD since 2008, also manages a sizeable photographic record of its tenancies and events in buildings along Hunter Street and the East End. Renew Newcastle shifted to a cloud-based image management platform in 2025 in part to address duplication issues that had accumulated over more than a decade of project documentation.
How Rotterdam and Medellín Handled It First
Rotterdam, the Dutch port city that shares significant economic DNA with Newcastle — heavy industry, a major port, an active just-transition narrative — moved aggressively on this issue in 2022. The city's municipal archives division adopted automated perceptual hashing tools to identify near-duplicate images across its public heritage database, reportedly cutting storage volume by around 30 percent within 18 months, according to reporting by Dutch public broadcaster NOS. The city made that project part of a wider digital governance reform tied to European Union open-data directives.
Medellín, the Colombian city often cited in urban regeneration comparisons with Newcastle, took a different approach. Its Archivo Histórico de Medellín partnered with a local university in 2023 to crowdsource the identification of duplicate or mislabelled heritage images, using public engagement to do work that would otherwise have required expensive software licensing. The project drew on Medellín's established tradition of participatory urbanism to solve what is essentially a data hygiene problem.
Newcastle's approach sits somewhere between the two. The council has the software tools — its 2025–26 budget allocated funds for digital records management upgrades, though the specific line item has not been publicly broken down — but the community-engagement dimension is largely absent so far. The University of Newcastle's involvement in heritage digitisation is the closest analogue to Medellín's university partnership model, though it remains focused on research outputs rather than public co-design.
For residents and organisations holding their own local image collections — community groups, sporting clubs along the Bathers Way foreshore, neighbourhood associations in Islington or Cooks Hill — the practical advice from digital archivists is consistent: run a deduplication pass before migrating to any new platform, use metadata standards like Dublin Core to tag files consistently, and check NSW State Records guidelines before deleting anything that might qualify as a public record. Getting ahead of this now is considerably cheaper than untangling it after the next server migration.
