Canberra's Duplicate Image Problem: How the Capital Stacks Up Against Cities Tackling Digital Asset Sprawl

The ACT government's Digital Records Directorate quietly flagged the issue in its 2025-26 annual procurement review: duplicate and near-duplicate images now account for a measurable share of storage overhead across territory agency systems, driving up cloud licensing costs and slowing retrieval times for public servants across Civic and Barton. The problem is not unique to Canberra, but the city's unusually high concentration of government and research bodies makes the stakes sharper here than almost anywhere else in Australia.

Duplicate image replacement — the process of identifying, consolidating and replacing redundant visual assets in digital asset management systems — has become a live operational issue for large bureaucracies worldwide. The trigger right now is money. Cloud storage pricing has shifted substantially since 2023, and agencies that once tolerated redundant file libraries are now being asked to justify every gigabyte. For a public service city where the Australian Public Service Commission estimates tens of thousands of staff work across dozens of portfolio agencies, even modest per-user storage waste multiplies quickly.

What Canberra's Institutions Are Actually Doing

The Australian National University's Scholarly Information Services team has been running a digital asset rationalisation project across its Acton campus systems since late 2024, focusing in part on image deduplication within its research data repositories. The University of Canberra, based in Bruce, has been piloting a separate workflow using open-source perceptual hashing tools to flag near-duplicate images in its communications and media archives — a lower-cost approach compared to commercial platforms used by some peer institutions.

At the federal level, the National Archives of Australia, whose main reading room sits on Queen Victoria Terrace in Parkes, has for several years maintained deduplication protocols as part of its digitisation standards framework. The challenge is that these efforts remain largely siloed. There is no whole-of-government ACT or Commonwealth standard mandating duplicate image replacement across agencies, which means the quality of digital housekeeping varies dramatically depending on which department a public servant works in.

Compare that to Wellington, where the New Zealand Department of Internal Affairs published a unified Digital Asset Management Policy in March 2025 that requires all central government agencies to run quarterly deduplication audits on image libraries above 10,000 files. Edinburgh City Council adopted a similar consolidated approach in 2024 under its Smart City programme, reducing its municipal image archive storage overhead by a reported 23 percent in the first year. Ottawa's Shared Services Canada, which provides IT infrastructure across federal departments, has embedded image deduplication into its standard onboarding process for new cloud storage contracts since January 2025.

The Cost Gap and What It Means for Canberrans

Storage costs are the clearest argument for action. Microsoft Azure and AWS, the two dominant cloud providers used across Commonwealth agencies, both price storage tiers that can reach several hundred dollars per terabyte per month depending on access frequency and redundancy settings. For agencies managing image libraries in the tens of thousands of files — routine for any department with a communications function — unmanaged duplication can represent thousands of dollars in avoidable annual spend.

The ACT government's Procurement and Capital Works directorate has not publicly committed to a territory-wide deduplication standard as of July 2026. Individual agencies continue to make their own decisions. That contrasts with the more centralised mandates now operating in Wellington and Ottawa, where the decision was taken out of individual agency hands entirely.

For Canberra public servants and the ANU and UC researchers who rely on shared digital infrastructure, the practical advice is straightforward: check whether your agency or faculty has a digital asset management policy that covers image deduplication, and if it does not, raise it with your IT governance team before the next budget cycle. Cloud storage contract renewals — typically annual — are the most effective leverage point. Agencies that build deduplication requirements into new contracts, rather than retrofitting them later, consistently report lower remediation costs. The cities that moved first on this, Wellington chief among them, did so at exactly that moment: contract renewal time.
