Perth Councils and Developers Scramble to Audit Visual Records After Duplicate Image Crisis Hits Property Listings

Perth's property sector spent the first week of July firefighting a sprawling duplicate image problem that has muddied listings across the metropolitan area, drawn complaints from buyers and prompted at least one major council to suspend automated uploads to its public-facing planning portal. The issue, which surfaced publicly on Monday 30 June when buyers began reporting mismatched photographs on listings in Subiaco and Canning Vale, has since spread to affect records held by agencies operating along the Stirling Highway corridor and as far south as Cockburn Central.

The timing is brutal. Perth's housing market is running at a pace that leaves almost no margin for administrative confusion. Demand driven by immigration growth, defence-sector workers relocating ahead of expanded work at HMAS Stirling on Garden Island, and Metronet-linked speculation around new station precincts has kept weekly listing volumes unusually high for winter. When images tied to one property appear on another — or when a sold dwelling's photographs resurface on a fresh listing — buyers lose trust in the entire dataset fast.

What Actually Happened This Week

The mechanical cause, according to technical documentation circulating among PropTech vendors in Perth's CBD, is a batch-processing fault inside image-management pipelines that several agencies share through a common third-party content delivery platform. When agencies bulk-upload photography ahead of Saturday open homes, a deduplication algorithm designed to save storage costs began tagging genuinely distinct images as duplicates and substituting archived photographs from previous campaigns on the same street or suburb. The result: a three-bedroom home on Canning Highway in Applecross appeared online this week carrying interior photographs of a property in Willagee, roughly four kilometres away.

REIWA, which maintains the state's peak real estate data infrastructure, confirmed via its website on Wednesday that it was aware of reported image discrepancies affecting a subset of listings on its portal. The organisation advised member agencies to manually verify all photographic assets attached to active campaigns before the Saturday 4 July open-home window. No figure for the number of affected listings has been confirmed publicly by REIWA as of Saturday morning.

The City of Stirling, which processes development application documents through its online planning portal on Okeover Road, Stirling, paused automated ingestion of supporting images submitted with DA lodgements from Tuesday afternoon while its IT team audited the pipeline. A notice on the portal advised applicants that documents submitted between 29 June and 2 July would be manually reviewed before being made publicly searchable, adding up to five business days to processing times for affected applications.

The Broader Cost to Buyers and Agents

For agencies, the practical damage is measurable. Re-photographing a metropolitan Perth property typically costs between $250 and $600 depending on floor area and drone requirements, based on rates advertised by several Perth-based property photography firms this week. Agencies that pushed multiple listings live between Monday and Wednesday face those costs multiplied across their portfolios, with no guarantee the platform vendor will reimburse them. Some smaller agencies in the northern suburbs, particularly around Joondalup and Wanneroo, have reportedly reverted to manually uploading individual images rather than using bulk-processing tools while the fault remains unresolved.

The episode also arrives as the McGowan-era digital-services reforms, continued under the current WA Labor government, have pushed more planning and property records online. Greater reliance on automated systems amplifies the blast radius when those systems fail.

For buyers and sellers with transactions in progress, the immediate advice from agency principals is straightforward: cross-reference any online listing photography against the physical address using Google Street View or, better, attend an in-person inspection before making offers. Anyone who submitted a development application to a metropolitan council between 29 June and 5 July should contact the relevant planning department directly to confirm their supporting documents are correctly attached to their file. REIWA's member helpline is available weekdays, and its portal carries a reporting tool under the listing detail page for flagging image errors. The platform vendor has not publicly stated a resolution date, but agencies have been told to expect a patch deployment no later than the week beginning 6 July.
