How Perth's Property Market Ended Up Drowning in Duplicate Listing Photos — and Who's Cleaning It Up

Perth's residential property market is grappling with a quiet but costly problem: duplicate and recycled listing images appearing across multiple properties on platforms including Domain and realestate.com.au, eroding buyer trust and in some cases misrepresenting homes that have changed significantly since they were last listed. The issue has worsened markedly since 2023, tracking almost exactly alongside the city's housing demand surge driven by interstate migration and AUKUS-related defence workforce arrivals in Rockingham and the northern suburbs.

The timing matters. Western Australia recorded its highest net interstate migration figures in over a decade during 2023 and 2024, compressing supply across suburbs from Ellenbrook to Fremantle and pushing median house prices in Perth past $800,000 by early 2026. Agencies scrambling to list properties faster than ever began leaning on image libraries, stock photography, and in some cases photos lifted directly from earlier sales of the same address — sometimes years-old shots that no longer reflected the property's condition or fit-out.

A Problem Built Over Years of Market Pressure

The roots go back further than the recent boom. Perth's real estate sector consolidated aggressively through the lean years of 2018 to 2021, when the market was flat and agency margins were thin. Photography budgets were cut. Many smaller agencies in suburbs like Midland, Balga, and Gosnells began sharing image contractors or simply reusing assets between listings, a practice that went largely unnoticed when transaction volumes were low.

The Real Estate Institute of Western Australia has acknowledged the sector faces standards challenges as volumes climb, though the Institute has not publicly specified any enforcement action against named agencies. Consumer Protection WA, sitting within the Department of Energy, Mines, Industry Regulation and Safety, fields complaints about misleading property advertising under the Australian Consumer Law. The number of property-related complaints received by the department rose by a reported 18 per cent in the 2024–25 financial year, according to figures the department published in its annual report, though not all complaints specifically relate to image misrepresentation.

PropTrack data published in early 2026 showed Perth listings turnover had accelerated to an average of 21 days on market — the fastest in the country at the time — leaving little room for agents to commission fresh photography between a vendor's decision to sell and the first open home. Some agencies in the Stirling and Wanneroo local government areas were managing portfolios of 40 or more active listings simultaneously per agent, according to industry commentary published in The West Australian in March 2026.

What the Fix Looks Like — and Who Has to Move First

The practical mechanics of duplicate image replacement are less complicated than the accountability question. Portal operators have the technical capacity to flag images using hash-matching and reverse image search tools. Realestate.com.au rolled out automated duplicate detection for commercial listings in 2024, but residential listings have not received equivalent treatment at scale across the Perth metro area.

The State Government's Metronet expansion — which is opening new residential corridors along the Yanchep and Thornlie–Cockburn lines — is adding fresh stock to suburbs like Eglinton, Alkimos, and Thornlie, all of which are seeing first-time listings from newly completed builds. Those properties represent an opportunity: new addresses, no image history, no temptation to recycle. Industry observers suggest that requiring statutory photography declarations as part of the Form 1 Residential Sale Contract could close the loophole at the point of listing rather than after the fact.

For buyers, the practical advice is blunt. Cross-check listing photos against Google Street View for the property address. Run images through a reverse image search before attending an inspection — particularly for older homes in established suburbs like Victoria Park, Bayswater, and Maylands, where the same terrace or post-war brick house may have been sold and re-listed multiple times over the past decade. If photos don't match what you find on the street, file a complaint with Consumer Protection WA before signing anything. The market is moving fast, but that's precisely when cutting corners on disclosure causes the most damage.
