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

Canberra's public sector is sitting on a digital storage problem that has been quietly compounding for years. Across ACT government agencies, federal departments headquartered along the parliamentary triangle, and research institutions including the Australian National University, redundant and duplicated image files have accumulated across shared drives, content management systems and archival platforms — inflating storage costs and creating compliance headaches under the Territory Records Act 2002.

The issue has sharpened in 2026 because several agencies face scheduled audits by the ACT Territory Records Office before the end of the financial year, and the ACT Labor government's digital modernisation push — part of its broader data strategy released in late 2024 — has put asset management under renewed scrutiny. Unresolved duplication doesn't just waste money. It creates legal uncertainty about which version of an image is the authoritative record, a question that matters enormously in planning disputes, infrastructure documentation and Freedom of Information requests.

Where the Problem Is Most Acute

The duplication headache is sharpest in agencies that have migrated between platforms without cleaning house. The ACT Planning directorate, which handles development applications for fast-growing suburbs like Gungahlin and Belconnen, holds thousands of site photographs tied to individual DA files. When those files moved from the legacy EDMS platform to newer cloud infrastructure, many images were copied rather than migrated cleanly, leaving parallel sets with no easy way to identify the master copy.

At the University of Canberra's Bruce campus, the library and research services team has been working since early 2025 to reconcile image assets held across three separate repositories — a problem familiar to ANU's Scholarly Communication team on Acton's Chifley Road precinct, which manages born-digital collections spanning decades. Neither institution is alone. The National Archives of Australia, based at its Queens Terrace facility in Parkes, flagged digital asset duplication as a risk category in its most recent corporate plan, though the scale of the issue across individual agencies remains an internal matter.

Storage is not cheap. Enterprise cloud storage for large public-sector tenants in Australia typically runs between $0.02 and $0.05 per gigabyte per month under whole-of-government panel agreements, and agencies collectively managing hundreds of terabytes of image assets can find duplication adding tens of thousands of dollars annually to their operating budgets — costs that ultimately come back to the ACT and federal budgets.

The Decisions That Will Define the Outcome

The next six months are pivotal. Three distinct choices are now on the table for Canberra agencies navigating this.

First, agencies must decide whether to run automated deduplication tools or invest in manual review. Automated tools are faster and cheaper but carry real risk: algorithms can incorrectly flag near-identical images — such as two sequential photographs of the same Northbourne Avenue construction site taken minutes apart — as true duplicates and delete one. Manual review preserves accuracy but is labour-intensive in agencies already stretched by public service efficiency reviews.

Second, agencies need to settle on a governance model before they touch a single file. Without a clear policy on who owns the authoritative copy — the originating directorate, a central records team, or IT — deduplication exercises can create new confusion rather than resolving old conflicts. The ACT Government's Digital, Data and Technology Solutions (DDTS) branch has been developing cross-agency guidance on exactly this question, though formal policy has not yet been published.

Third, there is the question of vendor lock-in. Some agencies are being pitched proprietary deduplication platforms that would make future migrations harder. Choosing open-standards tools now avoids that trap.

Agencies that defer these decisions risk entering the 2026-27 budget cycle with unresolved audit findings and no credible remediation plan — an uncomfortable position given the Territory Records Office's increased enforcement posture. The smarter path is to establish a working group before September, agree on a deduplication standard, and begin with a contained pilot in one directorate before scaling. Gungahlin's planning file archive, given its volume and its proximity to ongoing development activity along Flemington Road, is the most frequently cited candidate for a first run.

The technology is not the hard part. The decisions about accountability, process and risk tolerance are — and those are fundamentally human calls that no algorithm can make.
