Canberra's Duplicate Image Problem: The Key Decisions That Will Shape What Comes Next

Canberra's sprawling public sector has a digital housekeeping crisis. Agencies across the ACT and federal government are carrying enormous libraries of duplicate images — product shots, archival photographs, communications assets — stored redundantly across servers, costing taxpayers in licensing, storage, and staff time. The pressure to act is building, and the decisions made before the end of 2026 will define how bad the situation gets.

The issue has sharpened because of a confluence of pressures hitting simultaneously. The federal government's Digital Transformation Agency has been pushing departments toward centralised asset management as part of broader data consolidation work. At the same time, cloud storage costs have climbed sharply over the past two years, making duplicated assets a budget line item that chief information officers can no longer ignore. For an ACT economy where Commonwealth public servants make up a disproportionately large share of the workforce, the knock-on effects reach well beyond any single agency's IT budget.

Where the Decisions Are Being Made

Two institutions are at the centre of the immediate choices. The Australian National University, which manages one of the largest research image archives in the southern hemisphere from its Acton campus, has been auditing its digital asset management systems since early 2026. The National Archives of Australia, based in its Parkes building on Queen Victoria Terrace, faces a parallel challenge: a digitisation program running since 2022 has added millions of new files, and internal reviews have flagged redundancy rates that are straining infrastructure budgets.

For both organisations, the immediate fork in the road is whether to run automated deduplication tools — software that scans libraries and flags or deletes exact and near-exact copies — or to invest in a longer, more expensive human-led curation process. Neither path is cheap. Enterprise deduplication platforms used by organisations of comparable scale typically carry annual licensing costs starting around $180,000 for a mid-tier implementation, based on publicly available vendor pricing schedules. A human-led audit of an archive running into the hundreds of thousands of files can take 18 months or longer.

Smaller ACT government agencies have their own version of the problem. The ACT government's communications teams, spread across offices in the Civic precinct and out to service centres in Gungahlin and Belconnen, often maintain separate image libraries with no shared taxonomy. A single photograph of, say, the Gungahlin Town Centre light rail stop can exist in a dozen different folders across different directorates, each with a different file name and resolution.

The Timeline and What Needs to Happen

The window for action is narrow. The Digital Transformation Agency's current whole-of-government data strategy review is expected to produce recommendations by October 2026, according to the agency's published work program. Any agency that has not begun an internal audit before those recommendations land risks being caught flat-footed — potentially forced to retrofit solutions that don't match their existing infrastructure.

Practical steps being weighed by IT managers across the sector include adopting a single digital asset management platform across ACT government directorates, a move that would require cross-agency sign-off and almost certainly a procurement process running into mid-2027 at the earliest. A less ambitious option — mandating metadata standards so duplicates can at least be identified consistently — could be implemented faster but would not actually remove the problem.

For institutions like ANU and the National Archives, the calculus is different again. Both hold images with genuine archival value, meaning automated deletion carries real risk. A file flagged as a duplicate by an algorithm may turn out to be a distinct version of an image with separate provenance. Getting that wrong is not a recoverable mistake.

The decision that probably matters most is the one that gets made first: whether to treat duplicate image management as an IT problem to be solved by software, or as a records management problem that requires human expertise. Canberra, more than most cities, has both in abundance — the question is whether anyone in a position of authority is willing to commission the work before the backlog doubles again.
