Brisbane's Duplicate Image Problem: How the City Stacks Up Against Amsterdam, Singapore and Toronto

Brisbane City Council's digital asset management infrastructure is quietly cracking under the weight of a population boom that nobody planned for quite this fast. The council's internal image libraries — used across planning approvals, infrastructure documentation, the 2032 Olympics preparation unit, and public communications — now contain an estimated backlog of duplicate and redundant files running into the hundreds of thousands, according to IT procurement documents tabled at City Hall in March 2026. The clean-up, contracted to local digital services firm Aurecon under a $2.3 million scope of works agreed in February, is scheduled to run through to December.

Why does this matter now? Brisbane is not alone in confronting this, but the timing is particularly sharp. The SEQ region has absorbed significant interstate migration from New South Wales and Victoria over the past four years, driving infrastructure projects in Logan, Ipswich and the inner-north at a pace that has generated enormous volumes of site photography, aerial surveys and planning imagery. Each project produces its own image sets. Agencies duplicate them. Versions multiply. The 2032 Olympics infrastructure preparation office at 1 William Street has its own asset library that reportedly does not yet talk cleanly to the council's legacy system.

What Brisbane Is Doing — And What It Hasn't Done Yet

The Aurecon contract centres on deploying deduplication software across the council's Digital Asset Management platform, which runs on the OpenText Media Management framework. The scope targets the council's planning and environment division first, then works outward to transport and the major venues portfolio, which includes the Gabba precinct rebuild documentation. Gabba imagery alone — spanning demolition surveys, structural assessments and community consultation records — generated more than 40,000 individual files between January 2025 and June 2026, the procurement documents note.

The SpringHill-based council ICT team is also piloting a tagging and metadata standardisation protocol that would flag near-duplicate images at the point of upload rather than after the fact. That pilot is running inside the Brisbane Metro project documentation unit on Roma Street. It is not yet rolled out council-wide. The gap between pilot and full deployment is where Brisbane currently sits — which is, frankly, behind where some comparable cities already are.

How Singapore, Amsterdam and Toronto Compare

Singapore's Urban Redevelopment Authority completed a full deduplication overhaul of its GovTech-integrated asset library in late 2024, driven partly by the demands of its Long-Term Plan Review 2022. The URA now uses an AI-assisted similarity detection layer that flags duplicate images within 90 seconds of upload. Amsterdam's City Archives — the Stadsarchief — completed a comparable modernisation in 2023 using a hybrid system built around the Axiell Collections platform, covering more than 800,000 digital image records.

Toronto is the closest analogy in population and infrastructure trajectory. The City of Toronto's Digital Services division launched its Asset Deduplication Initiative in Q3 2024, budgeting CAD $4.1 million over 18 months. Toronto's system targets not just exact duplicates but perceptual duplicates — images that are functionally identical but saved at different resolutions or with minor cropping. Brisbane's current Aurecon contract does not yet include perceptual duplicate detection; that capability is listed as a Phase 2 option, contingent on a separate funding approval expected to go before the Finance and Economy Committee in September 2026.

The practical stakes are real. Duplicate images in planning databases slow assessment times, create version-control errors in development applications, and generate compliance risk when outdated site photographs are inadvertently submitted in lieu of current ones. In a city processing thousands of development applications annually across corridors from Northgate to Ripley Valley, that is not a marginal concern.

The September committee meeting will be the clearest indicator of whether Brisbane accelerates toward the Singapore and Amsterdam benchmark or stays in the mid-table bracket alongside cities still largely doing manual audits. Council's ICT leadership will need to make the case that Phase 2 funding is not a nice-to-have but an operational necessity for a city hosting the world in six years.
