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

Canberra's public sector is sitting on a digital storage problem years in the making. Duplicate images and redundant digital files have accumulated across federal and ACT government systems to the point where agencies face hard choices about what to keep, what to purge, and who pays for the clean-up — choices that can no longer be deferred as storage costs climb and a National Archives of Australia compliance review looms on the horizon.

The pressure is not abstract. The Australian Public Service Commission and the National Archives have both signalled that records management obligations under the Archives Act 1983 apply to digital assets, including photographic and scanned materials held across shared drives, cloud repositories, and legacy on-premise servers. For agencies concentrated along the Parliamentary Triangle and in the Barton and Woden employment precincts, that means audits are no longer hypothetical.

Why This Matters Now

Storage is not cheap at government scale. Enterprise cloud contracts — the kind that cover the bulk of Commonwealth data held by agencies based in Civic and Parkes — routinely run to tens of millions of dollars annually across the APS. Duplicate files directly inflate that spend. Industry benchmarks from the records management sector suggest duplicate and near-duplicate content can account for between 20 and 40 percent of unstructured data in large organisations, though figures vary sharply depending on how rigorously an agency has managed its file lifecycle to date.

The ACT government is in a parallel bind. The ACT Government Shared Services directorate, which handles digital infrastructure for Territory agencies, has been working through a broader digital modernisation program. The duplication question sits within that broader effort, but it has not yet reached a formal resolution stage. Agencies in the Civic precinct and those operating out of the Henty House complex in Belconnen are among those understood to be carrying legacy image libraries that predate current file-naming and deduplication standards.

At the Australian National University on Acton Peninsula, the university's own digital collections — including research image banks held by the ANU College of Arts and Social Sciences — present a different but related challenge. ANU is not subject to the Archives Act in the same way Commonwealth agencies are, but its researchers increasingly deposit materials into national repositories where duplication rules do apply.

The Decisions That Cannot Wait

Three choices are now unavoidable for any agency serious about getting this right before the 2027 review cycle. First, agencies must decide whether to run deduplication algorithmically — using software to flag identical or near-identical files — or manually, which is slower but produces more defensible audit trails for sensitive materials. Second, there is the question of who owns the decision to delete: records managers, IT teams, or the originating business unit. In practice, that fight over authority has stalled clean-up efforts in more than one Canberra directorate. Third, agencies need to settle on retention schedules that distinguish between a duplicate image that is genuinely redundant and one that carries metadata — date stamps, geolocation tags, camera identifiers — that could have evidentiary or historical value.

The National Archives published updated general records authorities covering digital materials, and agencies have until the next scheduled review period to demonstrate compliance. For smaller ACT government bodies, the September 2026 quarter is when internal audit cycles typically require a status report on digital asset management.

Practically, the cleanest path forward involves three steps in sequence: run an automated scan to establish the actual size of the duplicate problem, get a formal decision in writing from the relevant senior executive about deletion authority, and document the methodology so it survives a future Freedom of Information request or audit query. Agencies that skip the second step tend to find the first step's results sitting in a report that nobody acts on.

The agencies that move earliest will also find it easiest. Cloud contract renegotiations for several major Commonwealth clients are expected in the 2026-27 financial year, and demonstrable reductions in storage footprint give procurement teams genuine leverage at the table.
