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

A quiet but consequential reckoning is underway inside Canberra's public institutions. Duplicate digital images — the same photograph, scan or graphic stored multiple times across disconnected servers — have accumulated in government and university archives to the point where administrators can no longer ignore the storage costs, the compliance risks, or the sheer administrative chaos of not knowing which version of a file is authoritative.

For a city whose economy runs on the federal and territory public service, this is not a niche IT problem. It is a records management and accountability issue. The ACT Government's Digital Strategy, which set a framework for managing government data assets, named deduplication of image assets as a specific area requiring agency-level action. Several directorates have been quietly auditing their holdings since early 2026, with the results now feeding into budget and procurement decisions that are expected to crystallise before the end of the 2025–26 financial year.

Why the Timing Matters

The pressure is coming from multiple directions at once. Storage costs on government-managed cloud infrastructure have risen sharply over the past two years, and the ACT Auditor-General's office has flagged digital asset management as an area of broader records-keeping concern in recent performance audit cycles. Separately, the Australian National University — which holds one of the country's most significant digital image collections across its research libraries and the ANU Press — has been working through a platform migration that exposed just how many duplicate files had built up across departments and faculties.

At the ACT Government level, the most immediate decisions involve the Digital, Data and Technology Solutions directorate, which is understood to be evaluating at least two commercial deduplication platforms alongside open-source alternatives. A procurement decision is expected before 30 September 2026. The choice matters because whichever system is selected will likely be rolled out across multiple directorates, including Health, Education, and the Environment, Planning and Sustainable Development Directorate, which holds large volumes of aerial and cadastral imagery tied to the ACT's land management records.

In Gungahlin and Belconnen — the two fastest-growing parts of Canberra — planning records alone generate significant volumes of site photography, drone surveys and heritage documentation that currently sit in overlapping repositories. An officer at a Belconnen-area planning office managing a medium-complexity development application might encounter the same site photograph stored in three separate locations with slightly different filenames. That creates a practical problem: which image is the version of record if a dispute arises?

The Decisions That Will Define the Outcome

Three questions now sit at the centre of this process. First, who owns the deduplication function — IT infrastructure teams or records and information management specialists? The answer shapes everything from staff training budgets to legal liability. Second, how will agencies handle images that are near-duplicates rather than exact copies — a cropped version of a photograph, for instance, or one processed with different colour settings? Automated tools handle exact matches well but struggle with perceptual similarity, and the ACT's holdings include significant volumes of both.

Third, and most politically sensitive, is what happens to images deleted in error. The ACT's Territory Records Act 2002 imposes specific obligations on agencies to retain records for defined periods, and a deletion mistake involving a planning photograph or a heritage image could have legal consequences well beyond the inconvenience of a missing file.

The University of Canberra's library services team has taken a different approach, opting to freeze new ingestion into its legacy image store while a full audit is completed — a conservative move that buys time but is not sustainable past the northern-hemisphere academic year intake in early 2027, when fresh research image sets will arrive.

For public servants, researchers and contractors working with these systems, the practical advice from information management professionals is consistent: document your file provenance now, before any deduplication tool is switched on. The coming months will determine whether Canberra's institutions treat this as an infrastructure refresh or a fundamental rethink of how digital assets are governed. The difference between those two framings will show up — in audit findings, in court documents, or in quietly recovered storage bills — within the next two to three years.
