Canberra's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

Tens of thousands of duplicate digital images are clogging the records management systems of ACT government agencies, and a scheduled audit process set to conclude by September 2026 will force departments to decide what gets kept, what gets deleted, and who pays to clean up the mess. The issue has quietly grown across Canberra's public sector for years, but rising cloud storage costs and an upcoming territory-wide digital records review have brought it to a head.

The timing matters. The ACT Government's Digital Strategy 2025–2028, which sets binding targets for agencies to rationalise their data holdings and reduce redundant storage, has passed its first-year checkpoint. Agencies that fail to demonstrate measurable progress risk losing priority access to the territory's shared cloud procurement agreements — a financial incentive that is concentrating minds in IT departments from Civic to Tuggeranong.

Where the Problem Is Worst

The duplication burden falls unevenly. Agencies with large public-facing programs — those managing housing applications in Gungahlin, health infrastructure photography from Canberra Hospital on Yamba Drive, or planning records from the Environment, Planning and Sustainable Development Directorate on Phillip's Constitution Avenue — have accumulated image libraries that, in some cases, have never been systematically reviewed. Staff turnover, the shift to remote work during 2020 and 2021, and successive migrations between storage platforms have left folders full of near-identical files with no clear ownership.

The Australian National University faces a parallel challenge. The university's research data services team, operating out of the Chifley Library precinct on the Acton campus, manages image datasets across dozens of active research projects. Duplicate images in scientific datasets carry a particular risk: they can skew analysis, inflate apparent sample sizes, and compromise the integrity of published findings. ANU updated its Research Data Management Policy in early 2025, explicitly flagging deduplication as a researcher responsibility — but enforcement remains patchy.

At the University of Canberra's Bruce campus, the library and IT services division has been piloting automated deduplication software since February 2026 as part of a broader digital asset management overhaul. Early results, shared at a Canberra region higher education IT forum held at UC in April, suggested the pilot identified redundant files accounting for roughly 18 percent of total image storage volume — a figure consistent with benchmarks from similar institutions in Melbourne and Brisbane.

The Decisions No One Wants to Make

The hard part is not finding the duplicates. Modern deduplication tools can do that in hours. The hard part is deciding what counts as a true duplicate when images differ by metadata, resolution, or timestamp — and who has the authority to approve deletion of records that may carry legal or archival obligations under the Territory Records Act 2002.

Under that legislation, certain classes of government records cannot be destroyed without approval from the Territory Records Office, which operates under the Chief Minister, Treasury and Economic Development Directorate. For images created in connection with planning decisions, heritage assessments, or infrastructure contracts, that approval process can take months. Agencies racing to meet the September audit deadline are already flagging that the records approval bottleneck could leave them short of their targets.

Private sector businesses in the city face no such legislative constraint but carry their own costs. Cloud storage pricing for ACT government-aligned providers has increased since 2024, and small businesses operating from Braddon, Kingston Foreshore, or the Fyshwick commercial district that use image-heavy platforms — architects, designers, real estate agencies — are finding that unmanaged duplicate libraries translate directly into monthly bills.

What happens next depends on three converging decisions: whether the Territory Records Office accelerates its approvals process before September, whether agencies adopt shared deduplication tooling through the government's ICT procurement panel, and whether ANU and UC formalise their own policies into enforceable researcher obligations rather than guidelines. A working group drawn from the ACT Government's Digital, Data and Technology Solutions division is expected to report recommendations to relevant directorates before the end of July 2026. That report will set the template — not just for the current audit, but for how Canberra's public sector manages its exploding image data load for the rest of the decade.
