ACT Government's Digital Archive Push Hits Snag Over Thousands of Duplicate Images This Week

The ACT Government's digital records program struck a significant operational hurdle this week after an internal audit flagged thousands of duplicate images embedded across multiple agency databases, forcing a temporary slowdown in the rollout of its centralised archive platform. The issue, which emerged during a scheduled review in the last week of June, is understood to affect records held by at least three territory directorates.

The timing is awkward. The ACT has been accelerating its push to digitise public records since the Access Canberra service modernisation agenda picked up pace in 2024, and the duplicate image problem is the kind of technical debt that accumulates when agencies migrate legacy systems without a unified file-management protocol in place. With the broader Light Rail Stage 2 corridor through Civic and Northbourne Avenue generating a fresh wave of planning and infrastructure documents, the volume of imagery flowing into territory systems has grown sharply.

What the Duplicate Problem Actually Means

Duplicate images in a government archive are more than a storage nuisance. They create indexing errors, slow down Freedom of Information searches, and can cause discrepancies in official records — particularly for planning documents tied to addresses in fast-growing suburbs like Gungahlin and Belconnen, where development applications have been running at high volume. When two versions of an aerial survey image or a building inspection photograph carry different metadata tags, the downstream consequences for planning officers and legal teams can be material.

The ACT's digital records infrastructure is managed through the Territory Records Office, which sits within the Chief Minister, Treasury and Cabinet Directorate. The office oversees compliance with the Territory Records Act 2002, which requires agencies to maintain accurate, accessible records of government activity. A duplicate image that replaces or shadows an official document without a proper audit trail can put an agency in a difficult compliance position under that legislation.

The Australian National University's archives and records management program, based on Acton Peninsula, has previously flagged in research outputs that government digitisation projects across Australian jurisdictions frequently underestimate the cost of deduplication — the process of identifying and safely removing or consolidating redundant files. Commercial deduplication software licences typically run between $15,000 and $80,000 annually depending on the volume of records under management, though government procurement arrangements often differ from list prices.

Canberra's Digital Records System Under Pressure

The ACT's Territory Records Office has been working with agencies to implement a replacement image protocol — a structured process for identifying which version of a duplicated file is the authoritative record, retiring the redundant copy, and logging the decision. That process, straightforward in principle, becomes labour-intensive at scale. Sources familiar with government records work — without attribution to any individual — describe the manual review component as the bottleneck most agencies underestimate.

Civic Square, which houses the ACT government's main administrative offices, has been the administrative centre of the deduplication review this week. Staff from the Transport Canberra and City Services Directorate were also drawn into consultations over image files related to infrastructure works along Flemington Road in the Gungahlin corridor, where road and light rail planning imagery had reportedly been ingested into two separate systems in parallel.

The University of Canberra's Faculty of Arts and Design, which runs a digital curation research group, published a working paper in March 2026 noting that duplicate image rates of between 8 and 14 per cent are common in government migration projects — a range that, if applied to a large territory archive, could represent tens of thousands of individual files requiring human review.

For Canberrans interacting with Access Canberra services — whether lodging a development application in Tuggeranong or requesting historical planning records — the practical advice is to allow additional processing time on requests lodged in July while the audit and replacement work continues. The Territory Records Office has not indicated a public-facing deadline for resolution, but agencies have been advised internally to treat the deduplication review as a priority task through the end of the financial year adjustment period. Checking that any documents submitted digitally have been acknowledged with a reference number remains the safest way to confirm they have entered the system correctly.
