By the Numbers: Perth's Duplicate Image Problem Is Costing Businesses More Than They Think

Perth businesses are sitting on digital libraries bloated with duplicate images, and the bill for storing, managing and legally clearing that redundant content is quietly climbing. Across WA's property marketing sector alone, industry estimates suggest duplicate or near-identical image files can account for between 30 and 60 per cent of a company's total digital asset storage — a proportion that balloons further when resources companies and state government agencies are factored in.

The issue has sharpened in 2026 for a specific reason: the WA State Government's Digital Services Policy, updated in March, now requires agencies to demonstrate data efficiency benchmarks as part of annual ICT reporting. Agencies that cannot show active deduplication protocols risk losing priority access to the state's shared cloud infrastructure, which is managed through the Department of Finance's GovNext-ICT program.

What the Numbers Actually Show

The scale is not trivial. A mid-sized Perth real estate agency operating across the Stirling, Joondalup and Cockburn local government areas — each seeing sustained listing volumes driven by population growth tied to immigration and AUKUS-related workforce arrivals — can accumulate upward of 400,000 digital image files in a single financial year. Without automated deduplication tools, resized versions, re-exported JPEGs and renamed copies of the same property photograph routinely inflate that number by a factor of three or more.

Cloud storage pricing on Australian data centres — including the Canberra and Perth nodes used by WA government and major corporates — sits at roughly $0.023 per gigabyte per month for standard object storage as of mid-2026. A library of one million unmanaged image files, averaging 4MB each, costs around $92 a month just to store. That figure compounds fast when backup redundancy, egress fees and staff time spent manually hunting duplicates are added. For an agency running 12 months of unmanaged growth, the annual bill can exceed $15,000 before a single person has opened a file.

The City of Perth's own digital records team flagged the duplication problem internally after a 2025 audit of assets held on its Dropbox Business and SharePoint environments found that approximately one in four image files was a duplicate or near-duplicate of another file already in the system. The audit, referenced in the city's 2025–26 Annual Business Plan, prompted a tender for automated deduplication software that closed in May 2026.

Why Perth's Growth Is Making It Worse

Housing demand driven by the Metronet corridor — particularly around new stations at Morley and Ellenbrook — has pushed property marketing teams to produce image content at a pace that outstrips any manual cataloguing system. Agents from offices in Midland, Armadale and Cannington are uploading listing photos taken by multiple photographers, often with overlapping shoots of the same property at different stages of preparation. The result is image libraries that are, in practice, unmanageable without software intervention.

Resources companies headquartered along St Georges Terrace face a parallel problem. Site photography from iron ore operations in the Pilbara is routinely distributed to multiple internal teams — HSE, communications, investor relations — with each department saving local copies. A single site visit can generate a working library of 2,000 photographs that, after distribution, exists in six or seven separate folders across an organisation's network with no deduplication layer in place.

The practical upshot for Perth businesses is straightforward. Organisations still relying on manual file-naming conventions and folder structures should prioritise an audit of current digital asset volumes before the next financial year's ICT budget cycle, which for most WA government agencies closes in October. Commercial tools capable of perceptual hashing — a technique that identifies visually similar images even when file names differ — are available from around $300 per month for small-to-mid-tier deployments. For larger organisations with complex multi-site operations, enterprise licences typically start at $2,000 per month. The GovNext-ICT shared services framework, administered through the WA Department of Finance on Havelock Street in West Perth, provides a procurement pathway that can reduce that cost for eligible public sector bodies. The deduplication problem is solvable. The question is whether organisations act before the storage bill makes the decision for them.
