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

Tens of thousands of duplicate images have accumulated across ACT government digital asset systems, creating storage inefficiencies, compliance headaches and real costs for agencies operating out of buildings from Civic to the Tuggeranong Town Centre. The problem is not new, but a convergence of storage contract renewals and an ACT Government digital records audit scheduled for completion by September 2026 has forced the issue onto agency IT calendars.

The timing matters. Federal and territory public servants — who make up the single largest employment bloc in the ACT — generate enormous volumes of digital content every year. Departmental photography, planning documents, infrastructure records and communications assets all flow through shared repositories. When deduplication is neglected, the same image can exist in dozens of folders simultaneously, inflating storage costs and making retrieval slower and less reliable.

What's at Stake in Canberra's Digital Storerooms

The Australian National University and the University of Canberra both maintain substantial digital asset libraries for research, marketing and archival purposes. For institutions of that scale, duplicate imagery is more than a tidiness problem — it creates version-control risks, where an outdated or incorrect image remains in active circulation alongside the correct one. ANU's Chifley Library precinct and UC's Bruce campus each run independent content management systems, and neither is immune to the accumulation problem that affects organisations managing thousands of files annually.

At the territory government level, the ACT Government Directorate responsible for digital services has been working through a broader data hygiene program that encompasses duplicate image replacement as one line item. The process typically involves three stages: automated detection of duplicate files using hash-matching tools, human review of flagged content to confirm replacements are appropriate, and then a controlled deletion or archiving phase. The human review step is where projects most often stall, because it requires staff time that busy agencies operating on tight budgets struggle to allocate.

Gungahlin and Belconnen — the two fastest-growing residential corridors in the ACT — have generated significant volumes of planning and infrastructure photography over the past decade as development approvals multiplied. Records held by the ACT Planning directorate covering those areas are understood to be among the larger repositories flagged for deduplication work, though the directorate has not published a detailed project timeline publicly.

The Decisions That Will Define the Outcome

Three choices now face agencies and institutions working through duplicate image replacement programs. The first is whether to run deduplication retrospectively across entire legacy archives or to set a cutoff date — say, January 2024 — and clean only newer material. A full retrospective pass is more thorough but far more resource-intensive. The second decision is whether to invest in permanent automated deduplication tools embedded in the asset management workflow, which carry upfront licensing costs typically in the range of thousands of dollars annually for enterprise-scale systems, or to treat this as a one-off manual project. The third, and arguably most consequential, is governance: who signs off on a deletion, and what sign-off trail is required to satisfy ACT records-management obligations under the Territory Records Act 2002.

That last question carries legal weight. The Territory Records Act sets out retention and disposal obligations that apply to records held by ACT public authorities. An image deleted without proper authorisation from an approved disposal schedule is not just a lost file — it is a potential compliance breach. Agencies that move quickly through deduplication without checking each file type against the applicable Records Disposal Schedule risk creating exactly the kind of audit finding they were trying to avoid.

The September 2026 audit deadline gives agencies roughly two months to demonstrate progress. Institutions outside the government — including ANU and UC — operate under different frameworks but face similar internal pressures from IT departments managing storage budgets. For public servants working out of offices along London Circuit or in the Dickson precinct, the practical upshot is likely to be mandatory reviews of shared drives before the end of the financial quarter. Agencies that move now, with clear governance documentation and an approved disposal path, will close out the audit in a far stronger position than those treating the deadline as someone else's problem.
