Perth's property market has a dirty little secret buried in its listing portals. Duplicate images — the same photographs recycled across multiple properties, sometimes across different suburbs — are appearing on real estate platforms at a rate that consumer advocates say undermines buyers' ability to make informed decisions in one of the most competitive housing markets in the country.
The issue has sharpened urgency because Perth's median house price crossed $800,000 in early 2026, according to figures published by the Real Estate Institute of Western Australia. At that price point, a buyer misled by stock photography or reused images is not making a minor mistake. They are potentially committing to the biggest financial decision of their life on the basis of a fiction.
How the Problem Plays Out on Perth Streets
The mechanics are straightforward. An agency photographs a renovated kitchen in a Subiaco terrace, then reuses that image — sometimes with minimal cropping — on a listing for a Mount Lawley unit. On platforms like realestate.com.au and Domain, where thumbnail images drive click-through rates, the practice can be difficult to spot without visiting the property in person. Buyers doing their initial research from interstate — a growing cohort given WA's resources and AUKUS defence workforce expansion around Henderson and Stirling Naval Base — are particularly exposed.
Consumer Protection WA, which sits within the Department of Energy, Mines, Industry Regulation and Safety, has jurisdiction over misleading conduct in property transactions under the Australian Consumer Law as applied in Western Australia. The agency has the power to issue infringement notices and pursue civil penalties, though its enforcement record on image-specific complaints has not been publicly detailed in any recent annual report.
The Real Estate Institute of Western Australia operates its own conduct standards for member agents, and its Code of Conduct requires that listings not misrepresent a property's features. Whether recycled photography constitutes a breach depends heavily on context — whether the image is explicitly labelled as a "similar property" example or presented as the actual dwelling.
The Decisions That Will Shape What Comes Next
Three decisions now sit on the table, and how they fall will determine whether the problem gets fixed or quietly persists.
First, the WA Labor government has an active review of property transaction rules sitting with the Department of Energy, Mines, Industry Regulation and Safety. Advocates have been pushing for mandatory image-authenticity declarations — a requirement that agents certify photographs depict the actual property being sold. Whether that recommendation survives into formal regulation, or gets diluted under industry pressure, is expected to become clearer before the end of the 2026 financial year.
Second, the major listing platforms face a technology decision. Automated duplicate-image detection tools — the same reverse-image technology widely used in copyright enforcement — could flag reused photographs before a listing goes live. Neither realestate.com.au nor Domain has publicly committed to mandatory deployment of such tools in WA. Platform-level intervention would be faster than regulatory change and would not require legislation.
Third, buyers themselves face a practical decision right now, particularly those purchasing without physically visiting Perth first. The State Revenue Office of Western Australia processes thousands of property transfers annually, and buyers relying solely on online listings before signing are taking on risk that has no legal remedy once settlement completes.
Real estate solicitors operating along St Georges Terrace and in Hay Street's legal precinct are increasingly advising clients to commission independent property reports and cross-check listing images through reverse-image searches before making offers. That advice costs time and money — typically $300 to $600 for a building inspection report — but it is the most reliable safeguard currently available while regulatory frameworks catch up.
Perth's housing demand is not going to ease. The city's population grew by roughly 55,000 people in the 2024-25 financial year, driven by interstate migration and skilled visa arrivals tied to resources projects in the Pilbara and defence construction in Rockingham. Every one of those new arrivals is a potential buyer or renter navigating a market where the images they trust could be borrowed from somewhere else entirely. The decisions made by regulators, platforms and agents in the coming months will set the standard for whether that trust is warranted.
