Sydney's Duplicate Image Problem: How the City Stacks Up Against London, Singapore and New York

Sydney's public sector is sitting on a sprawling mess of redundant digital assets, and the people paid to fix it are only just getting started. Councils, state agencies and cultural institutions across Greater Sydney collectively manage tens of millions of digital image files, many duplicated dozens of times across siloed servers — a problem that wastes storage budgets, slows procurement systems and creates legal headaches around image licensing.

The issue has sharpened in 2026 as the NSW Government's ongoing Digital.NSW strategy, which set a June 2026 deadline for agencies to submit digital asset audits, forces organisations to confront what has been quietly accumulating for years. Property NSW, which manages one of the largest real estate portfolios in the southern hemisphere, acknowledged in its 2025–26 annual operational plan that standardising digital asset management was a priority goal for the current financial year.

How Sydney Compares Globally

London's Government Digital Service began mandating deduplication protocols across Crown agencies in 2022, integrating them into the broader UK National Data Strategy. Singapore's Smart Nation initiative went further, deploying automated hash-matching tools across all statutory boards by early 2025, cutting redundant image storage in the public sector by a reported 34 percent. New York City's Department of Citywide Administrative Services completed a centralised digital asset management rollout across 45 city agencies in 2024, working with a vendor on West 34th Street whose contract was publicly reported at $US 6.2 million.

Sydney has no equivalent cross-government mandate yet. Each agency largely runs its own approach. The City of Sydney Council uses a cloud-based digital asset management platform introduced in 2023 under its Smart City Action Plan, but neighbouring Parramatta City Council — now the de facto capital of Western Sydney and home to more than 250,000 residents — operates a different system with limited interoperability. The result is that a photograph taken at Parramatta Square might exist in four or five formats across two councils and a state agency, each billed separately for storage and separately licensed for use.

The State Library of NSW, headquartered on Macquarie Street, has made public progress on its own archive. The Library's digitisation program, which catalogues historical images dating back to the 1840s, has used automated deduplication tools since 2021. But the Library operates independently of agencies like Transport for NSW or the Department of Planning, both of which hold massive imagery collections tied to infrastructure projects including Metro West.

The Cost Is Real, Even If Quietly Absorbed

Cloud storage is not free. Amazon Web Services and Microsoft Azure, which between them host the majority of NSW government data, charge in Australian dollar equivalents that have risen sharply since the AUD weakened against the USD through late 2025. A single terabyte of cloud storage now costs an agency roughly $25 to $30 per month on standard tiers — a figure that compounds quickly when unmanaged image libraries run into hundreds of terabytes.

In the private sector, Surry Hills and Pyrmont — home to Sydney's densest cluster of media production companies and creative agencies — have largely adopted deduplication as standard workflow practice. Several post-production firms in the Pyrmont precinct use software that flags duplicate frames at the point of ingest, a workflow borrowed from broadcast television and now standard across the sector. The gap between private sector discipline and public sector inertia is visible and widening.

Where does this leave Sydney compared with Singapore or London? Behind, broadly — but not irreparably so. The Digital.NSW roadmap points toward a unified government data catalogue, and if that catalogue eventually includes image asset standards, it could deliver the kind of cross-agency deduplication that Smart Nation achieved in 18 months. The practical next step for NSW residents and businesses dealing with government imagery — for development applications, heritage submissions or transport corridor documentation — is to check whether the relevant agency has a published digital asset policy before submitting files, to avoid contributing further to the problem. The Parramatta Development Assessment team, for one, publishes submission format requirements on its planning portal that specify file type and resolution limits, a small but meaningful step toward cleaner archives.
