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

The ACT Government is sitting on millions of duplicate digital images spread across its agencies, a problem that independent digital asset audits in comparable public-sector cities have found can consume anywhere from 18 to 30 percent of total cloud storage budgets. Canberra's situation is drawing scrutiny precisely because the federal capital runs one of the highest concentrations of document-heavy government departments per capita of any city its size in the world.

The timing matters. The ACT Government's whole-of-government digital transformation strategy, which accelerated following the 2023 restructure of Shared Services, has pushed agencies toward centralised cloud platforms — but the migration dragged legacy file libraries along with it, duplicates and all. A single image of, say, a planning document for the Northbourne Avenue light rail corridor might exist in three separate SharePoint libraries, two email archives, and a standalone network drive simultaneously. Multiply that across the 30,000-odd ACT public servants and the storage bill compounds fast.

What Other Cities Are Doing

Wellington's Department of Internal Affairs began a structured duplicate-detection program in early 2024 using automated deduplication tools across its core content management system. Edinburgh City Council, managing roughly 20,000 staff, reported in its 2025 annual ICT review that a 14-month deduplication project cut active image storage by 22 percent, freeing up the equivalent of several hundred terabytes of capacity. Ottawa's Treasury Board Secretariat mandated metadata tagging standards for all new digital assets from January 2025 onward, targeting the root cause rather than the symptom.

Canberra's approach has been more fragmented. The Australian National University, which manages its own vast digital asset library across the Acton campus and Chifley Library systems, began trialling AI-assisted image deduplication software in late 2025 — but that project sits outside ACT Government infrastructure entirely. The University of Canberra at Bruce has similarly run pilot programs through its library services, but again independently of any territory-wide coordination.

Inside the ACT Government, the Digital, Data and Technology Solutions directorate has flagged duplicate image management as a priority in its 2025–26 workplan, but a formal whole-of-government deduplication standard has not yet been published. Agencies in the Civic precinct, particularly those housed in the Canberra Nara Centre and along London Circuit, continue to operate with their own departmental protocols — which vary significantly.

The Cost and the Comparison

Cloud storage is not cheap at government scale. Enterprise-tier object storage pricing from major providers currently sits around $25 to $35 per terabyte per month for Australian-region data sovereignty compliant hosting. For a mid-size ACT agency holding even 50 terabytes of redundant image data — a conservative estimate given the scale of planning, health, and transport digitisation projects — that represents a recurring overhead of roughly $15,000 to $21,000 annually on images that serve no functional purpose.

Edinburgh's 22 percent storage reduction, applied to a comparable ACT Government cloud footprint, suggests the savings opportunity here runs into hundreds of thousands of dollars per year territory-wide. Wellington's program delivered measurable results within 18 months of implementation. Canberra has not yet set a comparable public benchmark or timeline.

The Gungahlin and Belconnen growth corridor projects have added particular pressure. Planning imagery, environmental assessments, and construction documentation from the light rail stage 2 planning process have generated enormous new digital asset volumes since 2024, and project managers working out of the Environment, Planning and Sustainable Development Directorate offices in Civic have raised concerns internally about inconsistent file management practices, according to publicly available directorate briefing documents tabled in the ACT Legislative Assembly.

For ACT public servants dealing with this day to day, the practical advice from comparable jurisdictions is consistent: push your agency's ICT team to prioritise metadata standards now, before the next major migration project locks in another layer of duplicates. Wellington and Edinburgh both found that retrofitting deduplication after a platform migration costs roughly three times what prevention costs upfront. The ACT's next major cloud infrastructure review is scheduled for the second quarter of 2027 — which leaves a narrow window to get ahead of the problem rather than clean it up afterward.
