Perth Councils Scramble to Scrub Duplicate Property Images From Public Portals — Here's Why It Matters to You

Property listings on public-facing council and state government portals across Perth are carrying duplicate and mismatched images — photos that show the wrong street frontage, a demolished structure, or a neighbour's home entirely — and local planning advocates say the problem is compounding confusion in one of Australia's tightest housing markets. The issue has surfaced sharply this year as the WA Labor government pushes forward with rezoning decisions tied to the Metronet rail corridor, where accurate property records are critical to development applications.

The stakes are not abstract. When a prospective buyer in Bassendean or a developer eyeing a corner block in Cannington pulls up a Landgate-linked property record, a duplicated or wrong image can send them to the wrong address, misrepresent site conditions, or create inconsistencies that stall a Development Application at the City of Swan or the City of Canning. With Perth's median house price sitting above $800,000 in the June 2026 quarter, according to the Real Estate Institute of Western Australia's most recent market report, a single misdirected assessment can carry six-figure consequences.

How Duplicate Images Get Into the System — and Stay There

The root cause is structural. Landgate, the WA state agency that manages property titles and spatial data, draws on imagery from multiple collection cycles. Suburbs photographed in different years can end up with layers of imagery that were never reconciled. When councils such as the City of Stirling or the Town of Victoria Park embed Landgate-sourced map tiles into their own online planning portals, they inherit those inconsistencies. A unit block built in 2019 might still show a vacant lot. A demolished granny flat might appear as an occupied dwelling.

The City of Stirling — which covers fast-growing suburbs including Karrinyup, Osborne Park and Balga — operates one of Perth's busiest online development inquiry platforms. Residents using the portal to check neighbouring land use or verify setback requirements are exposed to whatever imagery Landgate has attached to a given lot. The same problem appears on the City of Bayswater's ePathway planning portal, which handles applications across Maylands, Morley and Embleton. Neither council has publicly confirmed a formal audit program targeting duplicate image data as of July 2026.

The timing cuts against the city. The WA government's Metronet expansion has triggered rezoning across at least 18 station precincts between Yanchep and Byford. In those corridors, accurate visual records matter to infrastructure agencies, private developers and community members lodging objections. The Department of Planning, Lands and Heritage has been reviewing how spatial data feeds into its MRA-linked redevelopment frameworks, but no public timeline for a system-wide duplicate-image purge has been announced.

What Residents and Buyers Can Do Right Now

The practical advice from property professionals is blunt: never rely on portal imagery alone. Before lodging an application or making an offer, visit the site. Cross-reference what you see on a council portal against Google Street View, which updates its Perth coverage roughly every 12 to 18 months and tends to be more current than government tile sets. For formal development purposes, a licensed surveyor's report will always override any portal image in a contested application.

Residents who identify a specific duplicate or wrong image on a council portal can submit a correction request directly to Landgate through its Spatial Data Quality team. The agency accepts error reports for its property imagery index and is required to log and investigate each submission. The Landgate office is based on Midland Gate Drive in Midland, roughly 18 kilometres northeast of the Perth CBD.

The broader fix requires investment. Aerial survey contracts, ground-truthing programs and automated image-matching algorithms cost money at a time when WA's state budget surplus — strong as it has been on the back of iron ore royalties — is being directed toward infrastructure rather than data-hygiene programs. Until a systematic solution lands, the burden of catching errors falls on the people who can least afford to absorb the cost of getting it wrong: first-home buyers, small-scale developers and community members trying to understand what is being built next door.
