How Perth's Property Listings Ended Up Flooded With the Wrong Photos — and Why It Took Years to Fix

The house was on Canning Highway in Applecross. The photos showed a different house entirely — a brick veneer in Midland, photographed two years earlier for a rental listing that had long since closed. The buyer drove forty minutes to an inspection and turned around at the kerb. This kind of error, once rare, became common enough in Perth's residential property market that the Real Estate Institute of Western Australia flagged duplicate image problems as a formal compliance concern in its member guidance materials.

The issue matters now because the stakes have never been higher. Perth's median house price crossed $800,000 in 2025, according to data published by the Real Estate Institute of Western Australia, and a buyer making a decision based on photographs that belong to a different property is not just inconvenienced — they may be misled in a market where pre-inspection offers have become routine. The surge in interstate and overseas migration into suburbs like Baldivis, Ellenbrook and Alkimos has driven a wave of remote purchasing, where buyers in Sydney or Singapore are putting contracts on homes they have never physically inspected, relying entirely on what appears on realestate.com.au or Domain.

How the Duplication Problem Built Up

The roots of the problem are structural, not accidental. When agencies expanded rapidly during the 2020–2022 buying frenzy, uploading speed took priority over image auditing. Property management software used across Perth — including platforms widely adopted by agencies along St Georges Terrace and in the northern corridor agencies clustered around Joondalup — stores images against property IDs, not against specific listing cycles. When a property changes hands, or when a property management portfolio is migrated between agencies, image files frequently carry over attached to the wrong record.

The issue compounded as short-term rental platforms entered the picture. Properties in Fremantle and Cottesloe that cycled between Airbnb holiday listings and long-term rental listings sometimes had their photography sets mixed across platforms, then scraped and re-ingested into mainstream real estate portals with the wrong geotag. By 2024, REIWA's compliance team had received enough member queries on the subject to publish updated guidance on image provenance and metadata standards — though the specifics of that guidance are available only to member agencies.

Metronet's expansion added another layer. As new station precincts at Morley and Ellenbrook shifted suburb boundaries and postcodes in some database systems, properties in transitional zones were occasionally matched to image libraries for the wrong locality. An agent in Bassendean described the experience — without being named here — as discovering that a freshly listed home had been automatically populated with street-view and floor-plan images from a comparable property three suburbs away.

Where Things Stand Now, and What Buyers Should Do

The practical consequence for Perth buyers today is straightforward: do not assume that what you see in a listing gallery corresponds to the specific property being sold. Cross-check the address shown in photographs against the street number in the listing contract. On realestate.com.au, the map pin and the photo carousel are generated by different data pipelines and are not automatically reconciled. A mismatch between the two is a red flag worth raising with the selling agent before an inspection, not after.

For the industry, the pressure to clean up image databases is now coming from two directions simultaneously. Consumer protection provisions under the Australian Consumer Law, which apply to real estate marketing materials, create liability exposure for agencies that publish materially misleading photographs. And PropTech companies pitching AI-assisted duplicate detection tools have been actively courting Perth agencies since early 2026, arguing that automated image-matching software can flag mismatches at the point of upload rather than after a buyer complains.

REIWA has not yet mandated a technical standard for image verification across its membership. Whether the industry moves voluntarily or waits for a formal regulatory nudge from Consumer Protection WA — the state agency that handles complaints about misleading property advertising — is the question that will shape how quickly listings in suburbs from Scarborough to Serpentine get cleaned up. For now, the burden of checking falls on buyers themselves.
