Perth's Digital Asset Audit: The Key Decisions Ahead as Duplicate Image Crisis Hits Council Records

Perth's metropolitan councils are now confronting a decision that has been quietly building for several years: what to do with tens of thousands of duplicate digital images clogging government records systems, and who pays to fix it. The problem, long treated as a back-office nuisance, has sharpened into a live policy question as storage costs climb and Western Australia's property boom puts new pressure on planning departments to process applications faster.

The issue is not unique to Perth, but local circumstances make it more acute here. The City of Perth and surrounding local governments including the City of Stirling and the Town of Bassendean have each expanded their digital asset libraries significantly since 2020, driven partly by Metronet construction documentation, CCTV rollouts, and heritage imaging programs along corridors like Albany Highway and the Fremantle waterfront. Duplicate images — sometimes hundreds of near-identical files from drone surveys or site inspections — accumulate when upload protocols are inconsistent or when staff scan physical documents without checking existing records first.

The Cost Problem Nobody Budgeted For

Cloud storage is not cheap at government scale. Industry benchmarks from the Australian Government's Digital Transformation Agency suggest that poorly managed digital archives can inflate storage costs by 30 to 40 percent above what a properly deduplicated system would require. For a mid-sized council running thousands of planning files simultaneously, that gap is measurable in the annual IT budget.

The City of Stirling, which covers suburbs from Inglewood to Scarborough and manages one of the largest planning workloads in metropolitan Perth, has been expanding its digital asset management infrastructure as part of broader smart-city investment. The council's planning directorate processes a high volume of development applications each year, a figure that has risen sharply since the WA government's housing density reforms came into effect. Duplicate imagery embedded in those applications creates version-control problems: assessors can unknowingly rely on an older site photograph rather than the most recent one, potentially delaying sign-off.

At Joondalup's Lakeside precinct and along the Yagan Square civic zone in the Perth CBD, heritage and public art documentation programs have also generated large image libraries with variable file management standards. When project photographers submit deliverables without strict naming conventions, councils end up holding multiple copies of the same image under different file names — functionally invisible to staff who don't have time to audit every folder.

What Happens Next: Three Decisions That Will Shape the Fix

The path forward turns on three interconnected choices. First, councils must decide whether to pursue deduplication manually, using existing staff, or to procure specialist software. Automated deduplication tools vary widely in cost — enterprise-tier platforms typically carry annual licensing fees in the range of $15,000 to $80,000 depending on archive size — and the procurement process alone through Local Government Act-compliant tendering can take three to six months.

Second, the WA Department of Local Government, Sport and Cultural Industries will need to clarify whether updated digital record-keeping standards are coming. The department last revised its general disposal authority for local government records in 2023, but that framework predates the current scale of drone and high-resolution site photography now standard across development applications. Councils are waiting on guidance before committing to a single technical approach.

Third, and most practically, councils need to settle on a retention policy for duplicate images that have already been attached to approved planning decisions. Deleting them carries legal risk if a decision is ever challenged and the full image record is needed. Retaining them perpetuates the cost blowout. Archivists at the State Records Office of Western Australia, based on Barrack Street in the CBD, are understood to be developing advisory guidance on exactly this question, though no formal instrument has been published yet.

The practical advice for councils in the interim is straightforward: freeze new uploads to legacy folders, enforce file-naming standards from July 1 this year, and commission an audit before the next budget cycle closes in December. The deduplication problem did not appear overnight, and the clean-up won't either — but the decisions made in the second half of 2026 will determine whether Perth's local governments enter the next property cycle with records systems that help assessors or slow them down.
