How Perth's Property Market Became Ground Zero for Duplicate Listing Images — and Why It Took Years to Get Here

Perth's real estate sector is confronting a problem that has been building quietly for the better part of a decade: duplicate and misrepresented property images appearing across multiple listings, sometimes advertising entirely different homes in entirely different suburbs. The practice, once an occasional embarrassment, has become frequent enough that Consumer Protection WA received a measurable increase in complaints related to property advertising accuracy over the 2024–25 financial year, according to the agency's published annual report figures.

The timing matters. Perth's median house price crossed $800,000 in early 2026, according to REIWA data, and rental vacancy rates remained below one per cent for most of 2025. In that environment, buyers and renters make fast decisions — often placing deposits or signing leases after a single inspection or, increasingly, none at all. A misleading hero photograph on a listing isn't just an aesthetic irritant. It can determine whether a family in Ellenbrook commits to a lease on a property they have never physically entered.

How the Problem Took Root

The groundwork was laid well before the current boom. When Metronet construction accelerated through the Morley-Ellenbrook Line corridor from around 2021 onward, new housing estates opened faster than local photography contractors could service them. Developers and some smaller agencies began pulling stock images — sometimes legitimately licensed, sometimes not — from completed projects in other estates and attaching them to off-the-plan listings. The justification, rarely stated publicly, was that the homes would look roughly similar once built. The result was that a rendered kitchen photographed in a display home on Wanneroo Road in Joondalup would appear in listings for properties under construction in Baldivis, forty kilometres south.

Simultaneously, the national real estate portals — primarily realestate.com.au and Domain — automated significant portions of their image-ingestion pipelines. Agencies uploading hundreds of listings per month discovered that duplicate images rarely triggered any rejection mechanism. The portals' own terms of service prohibit misleading representations, but enforcement has historically relied on complaints rather than proactive scanning. Perth agencies, many of them managing portfolios swollen by the post-2022 interstate migration wave, were uploading images at a pace that made manual checking impractical.

The Stirling Naval Base expansion and the broader AUKUS-related workforce influx added a specific pressure point. Suburbs like Rockingham, Baldivis, and Henderson absorbed thousands of new defence-industry workers and their families, most of them unfamiliar with the local market. Many were relocating from interstate or overseas and conducting their property searches entirely online. That demographic — time-poor, geographically unfamiliar, and financially stretched — was precisely the cohort most vulnerable to listings that carried photographs of a different property's interior or a streetscape from three streets away.

Where the Sector Stands Now

The Real Estate Institute of Western Australia has acknowledged the issue in its professional development communications, and REIWA's Ethical Conduct Guidelines were updated in late 2024 to include explicit reference to digital image accuracy requirements. Agencies holding a current triennial licence under the Real Estate and Business Agents Act 1978 face disciplinary action through the State Administrative Tribunal if found in breach of misleading conduct provisions — though prosecutions specifically targeting image misrepresentation have been rare.

Some larger agencies operating out of the CBD strip along St Georges Terrace have invested in AI-assisted image verification tools that flag when a photograph has appeared in a prior listing. Smaller operators, particularly those managing properties in the outer southeastern corridor through Armadale and Kelmscott, generally lack the resources to do the same.

For buyers and renters navigating the current market, the practical advice from Consumer Protection WA is consistent: conduct a physical inspection before signing anything, use a reverse image search on every listing photograph, and report suspected misrepresentation through the Complaints Management System on the Consumer Protection website. Landlords and vendors should ask their agent explicitly which photographs were taken at the listed property and request metadata or a timestamped photographer's invoice as confirmation. The market is unlikely to cool enough to remove the underlying pressure — which means the responsibility for catching these problems, for now, falls largely on the people least positioned to carry it.
