Canberra's Duplicate Image Problem: How the Capital Stacks Up Against Cities Tackling the Same Digital Headache

Federal agencies based in Canberra are sitting on millions of duplicate digital images across their internal content management systems — a storage and governance problem that cities from Helsinki to Singapore have begun aggressively addressing, while the Australian Capital Territory is still mapping the scale of its own backlog.

The issue matters now because the Albanese government's ongoing public service modernisation agenda, which includes a renewed push for shared digital infrastructure across departments headquartered along the Parliamentary Triangle and in Barton, has put legacy data hygiene back on the table. Duplicate imagery — the same photograph or graphic asset stored multiple times under different filenames or in separate siloed systems — quietly inflates cloud storage costs, slows content retrieval, and creates compliance headaches under the National Archives of Australia Act.

What Other Cities Are Doing

Singapore's Government Technology Agency, known as GovTech, has publicly documented a deduplication initiative across its Whole-of-Government content repositories, targeting redundant assets that accumulated during the COVID-19 period when digital publishing by agencies surged. Helsinki's city administration completed a similar audit of its municipal image libraries in late 2024, identifying roughly 40 percent of stored assets as duplicates eligible for deletion or consolidation. Amsterdam's digital services team has gone further, deploying automated perceptual hashing tools — software that identifies visually identical or near-identical images regardless of filename — across the city's public communications archive since early 2025.

Canberra's situation is more fragmented. Unlike Helsinki, which operates through a single city government, the ACT manages its own territory assets separately from the dozens of Commonwealth departments whose offices fill Civic, Barton, and the sprawling campuses around Woden Town Centre. That jurisdictional split means there is no single deduplication effort — just a patchwork of agency-level initiatives at different stages of maturity.

Local Institutions Feeling the Pinch

The Australian National University in Acton and the University of Canberra in Bruce, both significant digital publishers in their own right, have each grappled with image asset sprawl as their web presences expanded across multiple faculties and research centres. ANU's digital team has been consolidating its content platform since 2023. The ACT Government's own digital communications unit, which manages public-facing content for territory services operating out of offices including those on Bowes Street in Phillip, has acknowledged internally that image library governance is a known gap, though no formal deduplication program has been publicly announced.

For Commonwealth agencies, the Digital Transformation Agency — headquartered at 50 Marcus Clarke Street in Civic — has broad responsibility for advising on digital best practice but does not mandate specific asset management tools at the departmental level. That advisory-only role leaves individual agencies to solve the problem at their own pace and with their own budget allocations. Cloud storage costs for Australian government entities using platforms such as Microsoft Azure and AWS have risen materially since 2022 as data volumes grew, though publicly available per-agency storage expenditure figures are limited to what appears in portfolio budget statements.

The gap between Canberra and more centralised city-states like Singapore is partly structural and partly cultural. Public servants here tend to work within departmental silos that were built before shared digital infrastructure was a policy priority. Helsinki's advantage is a single municipal ICT budget; Singapore's is a top-down mandate from GovTech with teeth. Canberra has neither of those levers pulling in the same direction at once.

For public servants and territory government staff dealing with the problem day-to-day, the practical advice from digital archivists is consistent: start with a content audit before deploying any deduplication tool, because automated hash-matching software can flag near-identical images — slightly different crops of the same photograph, for instance — that may each serve a legitimate purpose. The National Archives of Australia publishes disposal authorities that govern how long digital assets must be retained, and those schedules should be cross-referenced before any bulk deletion is approved. Getting that sequencing right is where cities that have moved fastest, Singapore and Amsterdam among them, have invested the most upfront effort — and where Canberra, for now, is still catching up.
