Officials, Experts and Industry Figures Weigh In on Canberra's Duplicate Image Problem

Duplicate images are costing Canberra's public institutions time and money, and the people responsible for managing them are no longer staying quiet about it. Across federal agencies headquartered in the Parliamentary Triangle, ACT government directorates, and the research divisions of the Australian National University on Acton Peninsula, the problem of redundant image files clogging digital asset management systems has become a genuine administrative headache — one that procurement officers, digital archivists and records managers say is overdue for a coordinated fix.

The issue has sharpened in 2026 partly because of scale. The ACT government's planning directorate, which handles development application files for fast-growing suburbs including Gungahlin and Belconnen, processes thousands of submitted documents each month. Many of those files arrive with photographic attachments — site photographs, heritage documentation, streetscape images — duplicated across multiple lodgements from the same applicants. Without automated deduplication tools, staff are manually identifying and removing repeat files, a process that digital records professionals say is unsustainable at current growth rates.

What the Experts Are Telling Agencies

Digital asset specialists working across the Canberra public service sector point to two overlapping problems. The first is storage: duplicated images consume server capacity without adding information value, and in large agencies that can translate directly into unnecessary cloud hosting expenditure. The second is retrieval accuracy — when the same image exists in a system under different file names or metadata tags, search results become cluttered, and staff risk working from outdated versions of visual records.

The National Archives of Australia, based on Queen Victoria Terrace in Parkes, has published guidance under its Digital Continuity 2020 Policy framework encouraging Commonwealth agencies to adopt image deduplication as part of broader records hygiene programs. That policy framework, which has been in effect since 2015 and updated progressively since, sets expectations around format normalisation and storage efficiency that apply directly to photographic and visual records. Records management professionals cite the framework regularly when making the case internally for deduplication investment.

At ANU, the university's library and archives division has been piloting automated deduplication processes for its digital image collections since at least early 2025, according to publicly available project documentation on the university's website. The collections include research photography, institutional records and historical image sets held at the Chifley Library on the Acton campus. The pilot is part of a broader digital infrastructure refresh that the university has been undertaking across multiple faculties.

The Local Angle: Housing Files and Heritage Records

In practical terms, the duplicate image problem shows up most visibly in two Canberra contexts: development planning files and heritage documentation. The ACT Heritage Council, which assesses places for inclusion on the ACT Heritage Register, relies heavily on photographic evidence submitted by applicants and community members. When the same site photographs are submitted multiple times — sometimes by different parties documenting the same location — staff must cross-reference submissions to avoid double-counting visual evidence or attributing images incorrectly.

The University of Canberra, based in Bruce, has separately flagged digital asset management as a priority in its library services planning documentation, noting that visual collections associated with research outputs require clear deduplication protocols to meet research data management standards set by the Australian Research Data Commons. Those standards, updated in 2024, explicitly address the handling of duplicate and near-duplicate files in institutional repositories.

For public servants navigating this in their day-to-day work, the practical advice from records professionals is consistent: establish a single authoritative source for image files at the point of ingest, use hash-based deduplication tools that identify identical files regardless of filename, and build metadata audits into annual records management reviews. Several ACT government directorates have begun including image deduplication checkpoints in their existing digital recordkeeping schedules, aligning the process with the territory's Information Management Framework rather than treating it as a standalone IT problem.

The conversation is unlikely to stay niche for long. As light rail stage 2 construction documentation accumulates and Gungahlin's development pipeline continues generating photographic submissions, the volume of images entering government systems will only grow. Agencies that haven't addressed the duplicate problem yet are, by most professional accounts, simply deferring a larger cleanup job.
