How Perth's Property Boom Created a Crisis in Duplicate Listing Images — and What the Industry Is Doing About It

Perth's real estate market has been running hot for three years, and the pressure has produced an unexpected casualty: the integrity of property listing photographs. Duplicate images — the same photos appearing across multiple listings, sometimes for properties in entirely different suburbs — have become a documented problem on major platforms operating in Western Australia, frustrating buyers and drawing scrutiny from industry bodies.

The timing matters. Perth's median house price crossed $800,000 earlier this year, according to figures published by the Real Estate Institute of Western Australia, and the volume of listings processed each week by agencies across the metropolitan area has climbed sharply since 2023. When turnaround times shrink and stock moves fast, corners get cut. Images pulled from old campaigns, stock photo libraries, or even neighbouring properties end up attached to new listings — sometimes by accident, sometimes not.

How the Pipeline Broke Down

The mechanics are straightforward. Most Perth agencies upload listing content through third-party software that feeds simultaneously to realestate.com.au, Domain, and their own websites. That pipeline was designed for a slower market. When an agent in Subiaco lists a two-bedroom unit on a Monday morning and needs it live before lunch, the image-checking step — which was never automated in most systems — gets skipped. A photo from a similar property on Hay Street or from a completed development in Claremont ends up tagged to an address in Inglewood or Morley.

The Real Estate Institute of Western Australia, based on Havelock Street in West Perth, has acknowledged the issue in member communications this year. Industry guidelines require that all photographs in a listing accurately represent the specific property being advertised. The Consumer Protection division of the WA Department of Mines, Industry Regulation and Safety has the power to investigate misleading advertising under the Australian Consumer Law, and complaints relating to property listings have been a recurring category in its caseload.

Metronet has added pressure to the picture. As new train stations open along the Ellenbrook and Morley–Ellenbrook lines, previously overlooked corridors have been flooded with listings. Developers and private sellers in suburbs like Whiteman and Bennett Springs entered the market rapidly, often without established relationships with professional photographers. The result was a shortcut culture that spread upward into more established agencies.

What the Platforms and Agencies Are Now Doing

Realestate.com.au introduced an automated image-fingerprinting flag in late 2025 that alerts listing agents when an uploaded photo matches one already indexed on the platform within the previous 24 months. The tool does not block uploads — it generates a warning. Several Perth agencies, including some operating out of the Stirling and Joondalup council areas, have since updated their internal checklists to treat those flags as mandatory review triggers rather than optional prompts.

The issue has a practical legal dimension. Under Australian Consumer Law, a property advertisement that contains a materially misleading image can constitute false or deceptive conduct, regardless of intent. Buyers who exchange contracts based on a listing featuring inaccurate photos have grounds for complaint and, depending on the circumstances, compensation. That exposure has concentrated minds at principal level across many Perth agencies faster than any regulator directive.

For buyers navigating the current market, the practical advice from consumer advocates is straightforward: reverse-image search key listing photos before making an offer, attend every inspection in person, and request the address history of any photograph that seems inconsistent with the property's described age or condition. Properties in recently developed corridors north of the Reid Highway deserve particular scrutiny, given the volume of new stock that hit platforms between 2024 and 2026 with minimal photographic oversight.

The REIWA has flagged updates to its member conduct guidelines, with a revised framework expected later in 2026 that would require agencies to retain records linking each listed image to a specific property address and inspection date. Whether that standard becomes enforceable — or remains aspirational — will depend on how seriously the state's Consumer Protection office decides to treat the complaints already sitting in its in-tray.
