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

Duplicate images embedded in government documents and digital records systems are wasting storage, distorting reporting and, in some cases, complicating Freedom of Information requests — and Canberra's sprawling public service is starting to take notice. The problem, long treated as a minor administrative nuisance, is gaining fresh urgency as agencies push to digitise legacy paper files and migrate records to cloud platforms ahead of a federal whole-of-government digital records deadline in late 2026.

The issue is straightforward in principle. When the same photograph, diagram or scanned document appears multiple times across a records management system — uploaded separately by different staff, attached to multiple correspondence threads or duplicated during system migrations — it inflates storage costs, muddies audit trails and can create conflicting versions of official records. For agencies processing Freedom of Information requests under the Freedom of Information Act 1982, duplicate images have caused reviewers to produce inconsistent redaction decisions across what are, in fact, identical files.

Why Canberra's Public Sector Is Particularly Exposed

The ACT's economy is dominated by Commonwealth agencies clustered in Barton, Parkes and Phillip, plus the ACT government's own directorates. Many of those bodies are simultaneously running legacy systems and new platforms — a transition environment where duplicate records multiply rapidly. The National Archives of Australia, based in Mitchell, issued updated guidance to agencies in early 2025 urging compliance with the Digital Continuity 2020 Policy, which requires agencies to manage records in accessible, interoperable digital formats. Duplicate images create direct compliance risks under that framework.

The Australian National University's 3A Institute, located on the Acton campus, has contributed research on data integrity in large institutional systems. While that work spans sectors well beyond government, records management specialists who follow the institute's output say the core finding — that data quality problems compound during migration events — applies directly to what Commonwealth agencies are now experiencing. Meanwhile, the University of Canberra's Faculty of Arts and Design, which runs programs in information management on the Bruce campus, has been fielding increased interest from ACT government directorates seeking professional development for records staff.

The ACT Government's Digital, Data and Technology Solutions (DDTS) branch, which sits within Chief Minister, Treasury and Cabinet Directorate and operates out of offices in Civic, has been coordinating a records remediation program across ACT government directorates. DDTS has not published a specific cost figure for duplicate image management, but a 2024 review of ACT government ICT expenditure tabled in the Legislative Assembly noted that unstructured data storage was among the top three cost drivers in the government's cloud hosting contracts.

What Remediation Actually Looks Like

Deduplication software tools — commercially available products used by agencies including Services Australia and the Australian Taxation Office — compare file hashes to identify identical images regardless of filename. The process sounds simple, but records managers caution that not all duplicates are identical at the binary level: scans of the same original document at different resolutions, or images resaved in different formats, can evade automated detection and require manual review.

The practical cost falls on agency staff. A records officer at a mid-sized Commonwealth agency in Barton, working under standard APS4 classification conditions, can spend a substantial portion of a remediation project on manual image review before automated tools can be reliably deployed. Industry estimates — drawn from procurement documents published on AusTender — suggest deduplication projects for agencies with archives exceeding one terabyte of unstructured image data routinely run to six-figure implementation costs.

For agencies and ACT directorates that have not yet begun a systematic review, records management specialists recommend starting with a file inventory before any system migration is scheduled. The National Archives' Check-up Digital self-assessment tool, available to all Commonwealth entities, includes a records storage module that flags duplicate file volumes as a risk indicator. ACT government bodies can access equivalent guidance through DDTS. Both programs recommend completing preliminary audits before the end of the 2026 calendar year, when the next major tranche of federal cloud migration contracts is expected to be executed.
