Duplicate Images Are Cluttering Canberra's Public Records — Here's Why Residents Should Care

Canberra's digital archives have a problem hiding in plain sight. Across ACT government portals, the Australian National University's institutional repositories and the ACT Heritage Library's digitised collection on Mildura Street in Griffith, duplicate images — identical or near-identical digital files stored multiple times — are consuming server space, muddying search results and, in some cases, causing outdated versions of official documents to surface ahead of current ones.

The issue has gained fresh urgency in mid-2026 as federal and territory agencies push deeper into digital-first record keeping. The ACT Government's Digital Strategy, which set 2025 as a milestone year for transitioning core public services online, has accelerated the volume of scanned, photographed and screen-captured materials entering agency systems. More files flowing in at speed means fewer resources devoted to quality control — and duplicates accumulate fast.

What This Means for Canberrans Day to Day

For residents in growth suburbs like Gungahlin and Belconnen, the practical consequences are not abstract. Development application portals maintained by the ACT Planning directorate rely on image attachments — site photos, architectural renders, heritage overlays — to give community members a clear picture of what is proposed for their street. When duplicate or superseded images appear in these records, residents responding to development applications during the statutory public comment period can end up reviewing the wrong version of a proposal.

The University of Canberra's library, on Kirinari Street in Bruce, flagged the duplicate image problem in a 2025 internal review of its digital collections management practices after staff found that scanning workflows across two separate departments had produced overlapping records for the same physical documents. While UC has not publicly released the full findings, the review prompted an update to the library's metadata standards — a signal that institutions around the capital are aware the problem is real and growing.

At the ACT Heritage Library, which holds photographic records stretching back to the early twentieth century, duplicate detection has become part of routine collection maintenance. The library's digitisation program, operating from its Civic Square location in the City, uses file-hashing software to flag exact-copy duplicates before ingestion. The harder challenge is near-duplicates — images taken seconds apart, or scanned twice at different resolutions — which automated tools frequently miss.

The Cost Is Real, Even If It's Invisible

Cloud storage is cheap by historical standards, but not free. The ACT Government's whole-of-government ICT expenditure runs into the hundreds of millions of dollars annually across infrastructure and services, and storage inefficiencies represent a genuine line item. Industry benchmarks from digital asset management research suggest that duplicate files can account for between 20 and 40 per cent of an unmanaged image repository's total size — though those figures vary significantly by organisation type and workflow maturity.

For community groups that rely on publicly accessible government image libraries — local historians in Tuggeranong, built-environment researchers at ANU's School of Architecture on the Acton campus, journalists pulling planning records — the duplication problem creates a time cost. Searching through redundant files to find the authoritative version of an image is not a dramatic burden, but multiplied across hundreds of users and thousands of searches, it erodes the efficiency gains that digital systems were supposed to deliver.

The fix is neither quick nor cheap. Organisations dealing with large legacy archives typically need a combination of automated deduplication tools, updated ingest policies and — most critically — staff time to resolve near-duplicates that require human judgment. For ACT government agencies already managing tight headcounts as Commonwealth public service reforms ripple through the capital's employment base, that staff time is genuinely scarce.

Residents who notice duplicate or outdated images in public planning portals or official government document systems can flag them directly through the ACT Planning directorate's feedback mechanism on its website, or contact the ACT Heritage Library at its Civic Square offices. The more systematically those reports come in, the stronger the case for dedicated remediation resources in the next budget cycle — with ACT Budget 2026-27 handed down in June, the earliest realistic funding window for any new program would be mid-2027.
