Canberra's Duplicate Image Problem: The Key Decisions Ahead for ACT Government Records

ACT government agencies are sitting on a problem they can no longer defer. Across departments from the Australian Capital Territory's directorate network to the sprawling records holdings at the ACT Law Courts complex on University Avenue, duplicate digital images have accumulated for years — consuming server storage, complicating freedom-of-information requests, and muddying the evidentiary chain for everything from planning approvals to social services files. The question now is who decides what gets deleted, and when.

The timing matters. The ACT government is mid-cycle on its Digital Canberra strategy, a framework that ties agency IT upgrades to a broader push for government efficiency ahead of the 2025–26 budget consolidation period. Duplicate image management — long treated as a back-office nuisance — has surfaced as a tangible cost pressure. Unresolved duplicates inflate cloud storage contracts, delay responses under the ACT's Freedom of Information Act 2016, and in some cases have caused version-control failures during planning disputes in high-growth corridors like Gungahlin and Belconnen.

What the Backlog Actually Looks Like

The Territory Records Office, which sits within the Chief Minister, Treasury and Economic Development Directorate on London Circuit, holds authority over how agencies classify and dispose of digital assets. Under the Territory Records Act 2002, agencies are required to maintain disposal schedules — but duplicate images that have never been formally classified occupy a legal grey zone. They are not officially records, yet deleting them without authorisation creates compliance exposure. That circular problem has let the backlog grow.

Estimates from comparable mid-size Australian jurisdictions suggest duplicate files can account for between 15 and 30 percent of an organisation's total digital storage footprint, though the ACT government has not published its own audit figure publicly. The University of Canberra's Centre for Creative and Cultural Research, which has examined digital preservation policy in government settings, has flagged the governance gap in published research — noting that without a clear classification trigger, agencies default to retention, which compounds the problem year on year.

At the Australian National University's Chifley Library on Acton Peninsula, archivists managing institutional repositories have developed in-house deduplication protocols that use hash-matching to flag identical files before human reviewers make the final call. That two-stage model — algorithm identifies, human decides — is now being studied by at least one ACT directorate as a possible template, though no procurement decision has been announced.

Three Decisions That Will Shape the Outcome

The immediate fork in the road involves three overlapping choices. First, the ACT government must decide whether deduplication becomes a whole-of-government program with central funding, or whether each directorate absorbs the cost independently. The latter path has already produced uneven results — Transport Canberra and City Services, which manages imagery from light rail infrastructure works along Flemington Road and the Northbourne Avenue corridor, has reportedly advanced further than smaller agencies, though no formal comparison has been published.

Second, the Territory Records Office will need to update its General Disposal Authority to explicitly address duplicate digital images. Without that regulatory update — which requires a public consultation period under the Territory Records Act — automated deletion tools remain legally risky even if the technology is ready. A consultation process typically runs eight to twelve weeks in the ACT context.

Third, agencies must settle on a vendor or in-house approach before the 2026–27 budget cycle closes for new capital bids. Procurement timelines in the ACT government generally require a business case to be lodged by September for consideration in the following May budget. That leaves roughly ten weeks for directorates to decide whether to proceed, and in what form.

For public servants working in Canberra's growth suburbs — where planning and land development files are particularly image-heavy — the practical upshot is simpler: duplicated site inspection photographs and scanned development application documents are making FOI turnarounds slower than they need to be. The ACT Civil and Administrative Tribunal at 2 Allsop Street has seen an uptick in timeliness complaints related to document production, a pressure that a functioning deduplication regime would directly ease. The decisions made in the next three months will determine whether that eases before the end of 2026, or drags into another budget year unresolved.
