Perth Councils and Developers Race to Fix a Digital Records Mess This Week

Perth's planning and property sector is mid-way through a significant digital clean-up this week, as local governments and private developers grapple with a backlog of duplicate and corrupted images clogging shared cadastral and development-assessment databases. The City of Perth and the City of Stirling have both confirmed active remediation work on their digital records systems, with the problem surfacing more visibly as Metronet corridor rezoning applications have pushed document volumes to new highs in 2026.

The issue matters now because WA's housing approvals pipeline is under extraordinary pressure. The state government's land release program across the Ellenbrook, Eglinton and Alkimos corridors is generating thousands of new development applications each month, and each one requires supporting imagery, site photographs, elevation drawings, heritage overlays, to be correctly attached in the Integrated Planning and Reporting Framework system used across most metropolitan councils. When duplicate image files occupy those records, assessors must manually verify which version is current before a decision can proceed, adding days to already stretched timelines.

Where the Problem Is Being Felt Most

Two locations have emerged as particular pressure points this week. At the City of Stirling's offices on Cedric Street in Innaloo, planning staff have been working through a remediation list affecting applications tied to the Scarborough Beach Road precinct, where high-density rezoning has generated some of the state's highest per-site document counts. Meanwhile, the Western Australian Planning Commission's Optima Centre facility on Havelock Street in West Perth, the central clearing house for district structure plans, has flagged that roughly 340 active application files contained at least one duplicate image attachment as of Monday, 30 June.

Councils are not the only ones scrambling. Several medium-sized architectural and planning consultancies operating out of the Northbridge and Leederville precinct have retooled their internal document-management workflows this month after clients reported approval delays traced back to duplicate submissions. The problem has a straightforward technical cause, automated upload scripts used by applicants often fail to detect when an image has already been lodged, resulting in second and sometimes third copies sitting inside the same file record. Assessors then flag the duplication, triggering a manual review loop.

The State Records Office of Western Australia, which sets archival standards for local government digital holdings, updated its guidance on image metadata requirements in April 2026, giving agencies a 90-day compliance window that expires in early July. That deadline has concentrated minds across metropolitan councils this week. The guidance specifies that JPEG and TIFF files lodged in planning records must carry unique SHA-256 hash identifiers to allow automated duplicate detection, a standard most councils' legacy systems were not built to enforce.

What Comes Next for Applicants and Homebuyers

For anyone waiting on a planning decision in Perth's northern or southern growth corridors, the immediate practical advice is straightforward: check with your planning consultant or surveyor that all images submitted with your application carry distinct filenames and correct metadata before lodgement. The City of Wanneroo, which processes the highest volume of greenfield applications in metropolitan Perth, published updated submission guidelines on its website on 1 July specifically addressing the duplicate-image problem, recommending that applicants use file-naming conventions that include the lot number, application date and a sequential image counter.

The City of Perth has indicated it expects its own remediation sweep to be complete before the end of the July school holidays, which would clear the backlog affecting inner-city heritage overlay applications in Northbridge and East Perth. The City of Stirling has not publicly committed to a completion date for its Cedric Street workload.

Longer term, the WA Department of Planning, Lands and Heritage is understood to be scoping an upgrade to the state's shared development-assessment platform that would bake in automated duplicate detection at the point of upload, removing the need for manual review entirely. That system upgrade, if funded in the next state budget cycle, would likely be the most durable fix to a problem that has grown steadily as Perth's building and population boom shows no sign of easing.
