ACT Government's Digital Archives Purge: What Happened This Week With Duplicate Image Replacement

The ACT Government's digital records team confirmed this week that a structured duplicate image replacement program is underway across multiple directorates, after an internal audit identified significant storage and data integrity problems stemming from years of unchecked image duplication in public-facing systems. The cleanup, being coordinated through the Chief Digital Officer's office in Canberra's civic precinct, affects everything from public planning portals to health service records.

The timing matters. The ACT is midway through a broader Digital Government Strategy refresh, and the duplication problem has become a concrete obstacle. Systems used by the ACT Planning directorate — which handles land development approvals across fast-growing suburbs like Gungahlin and Belconnen — have been flagged as carrying redundant image files that slow processing times and, in some documented cases, surface outdated maps or superseded development renders when residents lodge queries online.

What Triggered the Audit

The issue surfaced publicly in late June when a Gungahlin community forum noted that the ACT Planning portal was displaying duplicate and contradictory site images for at least two development applications near Gundaroo Drive. The discrepancy prompted a formal complaint to the ACT Ombudsman's office. By July 1, the Chief Digital Officer's directorate had widened the scope of its review beyond planning to include health, transport, and education systems.

Canberra Health Services, which runs Canberra Hospital at Garran and the Calvary Public Hospital Bruce facility, operates patient-facing web infrastructure that had not undergone a duplicate media audit since 2022, according to internal documents described to The Daily Canberra by a source familiar with the review. The University of Canberra's health clinic systems, which interface with ACT Health infrastructure, were also drawn into preliminary checks this week.

The Australian National University's digital collections team on Acton campus separately announced it is running its own deduplication sweep across the ANU Archives portal — a process the team says will affect roughly 14,000 image records held in the open-access Trove-linked collection. The ANU sweep is scheduled to conclude by August 15.

Practical Impact and What Comes Next

For residents, the most immediate effect is intermittent unavailability of image-heavy pages on the ACT Government's Access Canberra portal, particularly sections covering property information and suburb planning maps. The Digital Office has confirmed planned maintenance windows between 11 pm and 4 am on weekday nights through to July 18, during which replacement images — verified against current master files — will be uploaded to live systems.

Duplicate image problems in government digital infrastructure are not trivial. A 2024 report by the Australian National Audit Office, examining digital records practices across Commonwealth agencies, found that redundant file storage contributed to measurable inefficiencies in retrieval systems, with some agencies carrying duplicate media libraries that consumed storage equivalent to several years of fresh uploads. While that report focused on federal bodies, ACT directorates have used its framework as a benchmark for their own reviews.

The ACT's digital records team is using automated deduplication software already licensed under the whole-of-government Microsoft Azure agreement, meaning no additional procurement is required for this round of fixes. The ACT Government's digital infrastructure budget for 2025-26 included $4.2 million allocated to data quality and storage management programs, under the Digital Government Strategy line items tabled in the March budget.

Residents who have submitted online development or service applications in the past three months are advised to log back into Access Canberra after July 18 to confirm that supporting images attached to their submissions are displaying correctly. The Planning directorate has set up a dedicated inbox for discrepancy reports, accessible through the main planning.act.gov.au portal. Agencies expect the bulk of the replacement work to be completed before the end of July, ahead of a school-term surge in online service activity expected in late July when the winter break ends.
