Perth Agencies Race to Fix Duplicate Image Problem Swamping City's Digital Archives This Week

Perth's public and private sector organisations are confronting a growing headache: thousands of duplicate images clogging digital asset management systems, triggering compliance concerns and inflating storage costs at a time when IT budgets are already stretched. The issue came to a head this week when multiple agencies began publicly advertising contracts and internal reviews aimed at cleaning up their image libraries before the 2026–27 financial year gets into full swing.

The timing matters. Western Australia's state government is sitting on a budget surplus driven largely by iron ore royalties, but department heads have been instructed to demonstrate value for money on operational IT spend. Duplicate image bloat — where the same photograph, map tile, or technical diagram is stored dozens of times across different servers and platforms — directly inflates those costs. It also creates legal exposure when licensing agreements cover only a single use of a commercial image, yet copies are scattered across multiple databases.

Local Organisations Moving Fast

The City of Perth's digital communications team, based on Hay Street in the CBD, is understood to be auditing its content management system after routine maintenance flagged more than 4,000 potential duplicate assets across its public website and internal intranet. The audit was triggered after the city's migration to a new platform earlier this year left residual files from the legacy system still active on live pages.

Across the river in South Perth, the WA Museum's digital collections unit has been working with third-party software to deduplicate image records held within its Mosaic collections database. The museum's digitisation program, which accelerated significantly after its Boola Bardip building opened in 2020, now manages tens of thousands of high-resolution image files. Duplicates emerge when staff upload scans from multiple workstations without a centralised intake checkpoint.

The problem is not limited to government. Several real estate and property marketing firms operating out of West Perth's office precinct have flagged duplicate listing photographs as a workflow drain, particularly as housing demand in Perth remains intense and agencies are processing record numbers of rental and sales listings each week.

What the Data Shows — and What Comes Next

Industry benchmarks from digital asset management providers suggest that, in organisations without automated deduplication protocols, between 20 and 30 per cent of stored image files are redundant copies. For an agency managing 50,000 images on cloud infrastructure priced at standard Australian commercial rates, that redundancy can represent thousands of dollars in avoidable annual storage fees — before factoring in staff hours spent searching through cluttered libraries to locate the correct file.

Automated deduplication tools typically work by generating a perceptual hash — a digital fingerprint — for each image and flagging files that match above a set similarity threshold. The process can identify not just identical copies but near-duplicates: the same photograph saved at different resolutions, with slightly different crops, or with metadata stripped. Several Perth-based IT procurement officers have been trialling tools from both Australian and overseas vendors this quarter, with decisions expected before September 30.

For organisations that have not yet started, the practical advice from the industry is straightforward: begin with a read-only audit before deleting anything. Automated tools can generate false positives — flagging distinct images as duplicates because of compositional similarity — so human review of flagged batches remains essential, especially for archives with heritage or legal significance. The WA State Records Office, located in Alexander Drive in Midland, publishes retention and disposal schedules that govern how long certain government image records must be kept, which adds another layer of complexity to any bulk-deletion exercise.

Perth agencies that move quickly stand to consolidate storage infrastructure, reduce licensing risk, and free up staff time ahead of what is shaping up to be a busy second half of 2026. Those that delay face compounding the problem as new images continue to flow in from Metronet construction photography, AUKUS documentation, and the city's ongoing public communications output — all of which generate significant visual media every week.
