Canberra's Digital Archive Problem: What Officials, Experts and Key Figures Are Saying About Duplicate Image Replacement

Canberra's public sector has a storage problem hiding in plain sight. Across ACT government agencies, federal departments clustered along London Circuit and Constitution Avenue, and research bodies including the Australian National University, digital asset libraries have grown bloated with duplicate images — the same photograph stored dozens of times under different file names, in different folders, consuming server space and complicating record-keeping obligations under federal archival law.

The issue has moved from IT back-rooms to executive briefings in recent months, driven partly by ballooning cloud storage costs and partly by the federal government's push to consolidate digital infrastructure across the Australian Public Service. The Australian National Archives' digital continuity guidelines, last substantially updated in 2023, place explicit obligations on agencies to maintain accurate, non-redundant records — and duplicate image proliferation sits awkwardly against that framework.

What the Experts Are Saying

Specialists in digital asset management at the University of Canberra's Faculty of Arts and Design have been advising both ACT government bodies and several federal agencies on the scale of the challenge. The core argument from that community is straightforward: automated deduplication tools have matured significantly since 2020, but agencies are slow to adopt them because procurement rules favour established vendors and because staff training budgets have been cut.

ANU's School of Computing, based on the Acton campus, has published research examining how perceptual hashing algorithms — software that identifies visually identical or near-identical images regardless of file name or format — can reduce image library sizes by between 30 and 60 per cent without any loss of unique content. The practical implication for a department like Services Australia, which manages millions of client-facing documents and associated imagery, is substantial savings measured in terabytes of cloud storage per year.

The debate is not simply technical. Records managers point out that deleting or consolidating images without a rigorous audit trail can itself create compliance headaches. Under the Archives Act 1983, Commonwealth agencies cannot dispose of records — including digital images — without an approved Records Authority from the National Archives of Australia. That legal constraint means even clearly redundant duplicates cannot simply be bulk-deleted; each disposal action requires documented authorisation.

Local Agencies Caught Between Cost and Compliance

The ACT government's Digital Strategy, which covers agencies operating out of offices in Civic and the Canberra CBD more broadly, acknowledges the tension. The strategy, released by the ACT's Chief Digital Officer directorate, sets a target of reducing per-agency cloud expenditure by 15 per cent by the end of the 2026-27 financial year. Storage rationalisation — which includes addressing duplicate files — is listed as one pathway to that goal.

Gungahlin-based community services teams and Belconnen district offices, which have grown rapidly alongside those suburbs' population booms, are among the agencies that accumulated the largest image backlogs during COVID-era digitisation drives between 2020 and 2022. Staff were scanning and uploading documents at speed, with little time for quality control, and the result is repositories where the same form, photograph or scanned certificate may exist in four or five versions.

Independent digital governance consultants working with ACT public bodies — a sector with a growing presence around the Civic precinct — generally advise a three-stage approach: first, run a non-destructive audit using deduplication software to map the scale of the problem; second, apply the relevant Records Authority before any disposal; third, implement naming conventions and upload controls to prevent recurrence. The audit phase alone, for a mid-sized agency, typically runs between $40,000 and $120,000 depending on library size and system complexity, according to publicly available tender documents lodged with the ACT Government Contracts Register.

The practical advice from digital asset specialists is consistent: agencies that wait for a centralised whole-of-government solution before acting are likely to find the problem significantly worse by 2028, when the federal government's next ICT infrastructure review is scheduled. Starting with an internal audit now, even a manual sample of the largest shared drives, gives agencies a defensible baseline and a clearer case for procurement spend. For public servants in Canberra watching storage budgets tighten alongside housing costs and cost-of-living pressures more broadly, the message is simple — the duplicate image backlog is not an abstract IT problem, and the cost of ignoring it is measurable.
