Duplicate Images in Government Systems: What Officials, Experts and Key Figures Are Saying

Canberra's public service agencies are sitting on vast libraries of duplicated digital images — redundant files clogging storage systems, inflating IT budgets and creating compliance headaches — and a growing chorus of voices from the Australian National University, the ACT Government Directorate and federal agencies is pushing for a structured response before the problem compounds further.

The issue landed back in focus this week after the ACT Digital Strategy Coordination Office flagged duplicate image management as a priority area in its mid-year systems review, noting that unchecked file duplication across shared drives and cloud environments has a direct and measurable impact on storage expenditure. The review covers agencies operating out of the Civic precinct and stretches into service delivery hubs in Gungahlin and Belconnen, where rapid population growth has accelerated document digitisation over the past three years.

Why This Matters in the Capital

Canberra is not a typical city when it comes to digital infrastructure. The federal government workforce concentrated around Barton, Parkes and Forrest generates an unusually high volume of scanned documents, identity records and policy imagery — material that routinely gets duplicated as it moves between agencies, contractors and ministerial offices. The ACT Government's own Health Directorate, which manages records across Canberra Hospital in Garran and the University of Canberra Hospital in Bruce, has been working since early 2025 to audit image duplication inside its patient records system.

Researchers at the ANU College of Engineering, Computing and Cybernetics have been examining automated deduplication tools as part of a broader project on public sector data efficiency. While specific findings from that work have not yet been published, staff involved in the project have described the volume of redundant image data inside government environments as substantially larger than most department heads realise. The University of Canberra's Institute for Governance, based on Kirinari Street in Bruce, has separately flagged digital asset governance — including image duplication — as an area where ACT agencies lag behind counterparts in Victoria and Queensland.

Storage costs are not trivial. Enterprise cloud storage rates for Australian government-classified environments typically run considerably higher than commercial rates, and agencies working under the Australian Signals Directorate's cloud security framework face additional overhead for every gigabyte retained. The ACT Government's most recent budget, handed down in June 2026, allocated $43.6 million across digital infrastructure line items for the 2026-27 financial year, though the breakdown between active data management and legacy storage was not publicly itemised.

Practical Steps Being Discussed

The conversation is shifting from diagnosis to action. The Digital Transformation Agency, which operates out of premises on Constitution Avenue in Reid, has been developing guidance for Commonwealth entities on automated image deduplication as part of its broader Data and Digital Government Strategy. That strategy, released in 2023, set a target for agencies to reduce redundant data holdings, though enforcement mechanisms remain limited and progress has been uneven across portfolios.

At the ACT level, the Chief Digital Officer's office has been in contact with vendors offering perceptual hashing tools — software that identifies near-identical images even when file names or metadata differ — as a potential solution for agencies that cannot easily audit holdings manually. Perceptual hashing is already used by a number of Commonwealth scientific agencies and by the National Library of Australia in Parkes to manage digitised collection duplicates.

For public servants doing the day-to-day work, the practical advice circulating inside several Canberra agencies is straightforward: do not wait for a whole-of-government mandate before auditing shared drives. Agencies that have run voluntary deduplication exercises — including one reported informally within a Woden Valley-based regulatory body last year — found redundancy rates above 30 percent in image-heavy folders, delivering meaningful reductions in storage overhead within weeks of remediation.

The next formal checkpoint is expected at the ACT Digital Advisory Board's August 2026 meeting, where image data governance is listed as a standing agenda item. Whether a binding framework emerges from that process, or whether agencies continue managing the problem piecemeal, will depend in large part on how forcefully the Chief Minister's Directorate chooses to push the issue before the end of the financial quarter.
