How Perth's Property Market Created a Duplicate Image Crisis — and Why Agents Are Now Scrambling to Fix It

The problem did not appear overnight. Across Perth's real estate portals, the same photograph of a Baldivis bathroom or a Ellenbrook kitchen has been turning up in dozens of separate listings — sometimes years apart, sometimes simultaneously — misleading buyers and eroding trust in a market that has already tested patience with its pace and opacity.

Real Estate Institute of Western Australia data has consistently shown Perth as one of the country's tightest capital city markets over the past three years. Listing volumes dropped sharply from 2022 through to late 2024, leaving agents competing for a shrinking pool of available properties. In that environment, corners got cut. Photographs taken for a 2019 rental listing in Armadale quietly resurfaced on a 2024 sales campaign in Thornlie. Stock images of gleaming stone benchtops and ducted air-conditioning units were deployed across multiple agency brands without attribution or disclosure.

How the Pipeline Got Clogged

The mechanics are straightforward enough. Perth's property boom, which accelerated after the state border reopened in March 2022, compressed marketing timelines dramatically. Agencies operating out of offices along Stirling Highway in Nedlands and Albany Highway in Victoria Park were listing and relisting properties within weeks of settlement, often pulling imagery from shared internal databases rather than commissioning fresh shoots. Photography contractors, themselves stretched thin by demand, began supplying the same edited image sets to multiple clients when exclusivity agreements were vague or absent.

Realestate.com.au and Domain — the two dominant national portals through which most Perth buyers now conduct their searches — both operate automated content systems that ingest agency feeds. Neither portal has historically carried out real-time duplicate detection at the image level, though both have described image integrity as a priority in their published platform guidelines. The gap between policy and practice is where the problem lives.

The State Government's Metronet expansion has added a particular layer of complexity. As new train stations opened along the Morley-Ellenbrook Line and the Yanchep extension, property in surrounding suburbs attracted waves of speculative listings. Developers marketing off-the-plan units in Eglinton and Alkimos frequently used render images and display-suite photographs that were, by design, identical across different stock. Those images then migrated into resale listings long after completion, sometimes without any update to reflect actual building finishes.

Pressure Builds on Industry to Clean Up

Consumer Protection WA, which sits within the Department of Energy, Mines, Industry Regulation and Safety, has the authority to investigate misleading representations in property marketing under the Australian Consumer Law as applied in this state. The agency has handled complaints about property advertising misrepresentation in previous years, though the specific volume of image-duplication complaints has not been publicly disclosed.

The Real Estate Institute of Western Australia runs a professional standards framework that member agencies are expected to follow, including obligations around accurate property representation. Industry observers have noted that the framework does not currently include specific technical standards for image provenance or metadata verification — a gap that has become harder to defend as the tools to detect duplicate images have become cheaper and more widely available. Reverse-image search technology that once required enterprise software now runs in browser plugins costing nothing.

Perth buyers, particularly first-home buyers navigating the First Home Owner Grant and shared equity programs under the State Government's Keystart scheme, are arguably most exposed. A purchaser relying on portal images to assess a property in Mirrabooka or Balga before travelling to an open home is making decisions on incomplete information if those images belong to a different address or a different decade.

The practical fix, as several technology vendors pitching to WA agencies have argued in recent months, involves embedding image fingerprinting at the point of upload — flagging any photograph that matches an existing listing above a set similarity threshold before the listing goes live. Some larger franchise groups operating out of offices in Subiaco and West Perth are piloting exactly that approach. Whether the broader industry moves voluntarily or waits for a regulatory nudge from Consumer Protection WA will likely determine how quickly Perth buyers can trust what they see on a listing page.
