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

Thousands of duplicate digital images are sitting inside ACT government agency servers, university libraries, and public-facing content systems across Canberra — and the cost of ignoring the problem is growing. A push is now underway across several directorates to establish clear policy on how duplicates are identified, who decides what gets removed, and which assets get preserved. The decisions arriving in the next six to twelve months will shape how the territory manages its digital estate for years.

The timing is not accidental. The ACT Government's Digital Strategy, which covers the 2024–2028 period, commits agencies to reducing redundant data holdings and improving information architecture. Duplicate images — whether in public communications libraries, planning department records, or infrastructure project archives — represent one of the more tractable pieces of a broader data governance challenge. But tractable does not mean simple. Deleting the wrong file, or failing to establish a canonical version of an image used across multiple platforms, creates downstream problems for everything from Hansard records to Light Rail Stage 2 community consultation documents.

Where the Problem Lives in Canberra

The issue is particularly acute at two levels: inside ACT government's shared services environment on London Circuit, and inside the digital asset systems of the Australian National University in Acton. ANU's library holds one of the largest image collections of any institution in the territory, and staff have flagged internally that legacy digitisation projects — some running back to the early 2000s — produced significant duplication without consistent metadata tagging. The university has not publicly disclosed the scale of the problem.

At the Territory and Municipal Services directorate, which manages imagery related to infrastructure projects across growth suburbs including Gungahlin and Belconnen, the duplication question intersects directly with record-keeping obligations under the Territory Records Act 2002. Images captured during construction phases of projects on Flemington Road and around the Gungahlin Town Centre have, in some cases, been stored in multiple formats across separate team drives, creating version-control headaches when documents are requested under freedom of information provisions.

The University of Canberra, based in Bruce, has taken a more systematic approach. UC's library services team began an audit of its digital image holdings in late 2025, prioritising collections tied to its health sciences and architecture faculties. The audit is expected to conclude by September 2026, according to the university's published project schedule.

The Decisions That Matter Most

Three choices will define whether this cleanup effort sticks or becomes another half-finished government initiative. First: who has deletion authority? Agencies need a clear governance line — ideally a named records manager with sign-off power — rather than leaving the call to individual team members. Second: what technical standard gets used to identify duplicates? Perceptual hashing, which matches visually similar images even when file names differ, is now standard practice in comparable jurisdictions, but adoption across ACT directorates remains uneven. Third: how long does the transition window last? A compressed timeline risks accidental deletion; a drawn-out one allows the problem to compound.

For public servants working in the suburbs ringing the city centre — the ones processing land development applications from Casey or running community consultations out of the Belconnen Community Service on Benjamin Way — the practical upshot is simpler. Better duplicate management means faster search results, lower cloud storage costs, and cleaner evidence trails when decisions get scrutinised.

Storage costs are real. Commercial cloud storage for government-grade environments runs at roughly $30 to $50 per terabyte per month at current ACT procurement panel rates, and duplicates can easily inflate a department's footprint by 20 to 40 percent without anyone noticing until a budget review. A directorate sitting on 10 terabytes of duplicated images could be spending close to $6,000 extra per year for no operational benefit.

The next visible checkpoint is the ACT Government's whole-of-government data governance review, scheduled for the third quarter of 2026. Agencies that arrive at that review without a duplicate remediation plan on paper will face pointed questions. Those that do arrive with one — even a modest one covering a single image library — will be better positioned to shape how territory-wide standards get written.
