Perth Leads Australian Cities in Purging Duplicate Property Listing Images — But Global Rivals Are Moving Faster

Perth's real estate platforms are sitting on tens of thousands of duplicate and recycled property listing images — photographs reused across multiple sales cycles, misrepresenting the current condition of homes listed on REIWA and third-party portals including realestate.com.au and Domain. The problem has become acute enough that the Real Estate Institute of Western Australia flagged image integrity as a priority concern at its June 2026 industry briefing in West Perth.

The timing matters. Perth's median house price crossed $780,000 in early 2026, according to CoreLogic's April quarterly report, and interstate and overseas buyers — many arriving under expanded AUKUS defence workforce migration pathways or drawn by Metronet corridor development near stations like Morley and Ellenbrook — are making purchasing decisions based on digital listings alone. A recycled image from a 2019 sale, showing a kitchen that has since been gutted or a garden that no longer exists, is not a cosmetic irritant. For a buyer in Singapore or Melbourne clicking through realestate.com.au at midnight, it can be the entire basis of an offer.

What Perth Is Actually Doing About It

REIWA introduced a voluntary image-dating protocol in March 2026, requiring member agencies to timestamp listing photographs and flag any image older than 18 months. Uptake has been uneven. Agencies concentrated along the high-turnover coastal strip from Scarborough to Cottesloe have largely complied, according to industry observers, while smaller independents in the southeastern suburbs — Cannington, Thornlie and Gosnells — have been slower to adjust workflows.

PropTrack, the data arm of REA Group, has been piloting an automated duplicate-detection algorithm across its Australian database since February 2026. The tool cross-references image metadata and pixel signatures to identify photographs appearing in more than one active listing or reused from a delisted property. In Perth specifically, PropTrack's trial identified more than 4,200 suspect image instances across active listings in the three months to May 2026, a figure the company shared at the Digital Property Summit held at the Crown Perth convention centre in May. That number represents roughly 6 percent of all active residential listings scanned in WA during the trial window.

Six percent is not catastrophic, but it compares poorly with results from comparable cities elsewhere. Amsterdam's Funda portal, which mandates photographer accreditation and image-refresh requirements tied to each new listing contract, reported a duplicate image rate below 1.5 percent in its 2025 annual transparency report. Auckland's OneRoof platform, operated by NZME, completed a full database audit in late 2024 and now uses AI-assisted flagging as a standard listing step, bringing its self-reported duplication rate down to under 2 percent. Singapore's PropertyGuru enforces a 90-day image expiry on all residential listings as a condition of platform access.

The Gap Between Policy and Practice

Perth's challenge is partly structural. Western Australia's real estate sector is heavily fragmented, with a large number of boutique agencies operating across the 1.4-million-square-kilometre state. Rolling out uniform image standards to an agency in Tom Price is a different administrative task from doing the same in Subiaco. REIWA's protocol is voluntary, not legislated, and Consumer Protection WA — the state body with oversight of real estate advertising standards — has not yet issued specific guidance on digital image currency as distinct from written misrepresentation.

The pressure is building from two directions. Buyers who have lodged formal complaints about misleading listings with Consumer Protection WA increased in number during the 2025–26 financial year, though the agency has not yet published a final breakdown by complaint category. Separately, the WA Department of Finance's housing affordability task force, established under the Cook government's 2025 budget, has identified transparent digital listing standards as a supporting measure for market confidence.

For Perth buyers navigating this imperfect system right now, the practical steps are straightforward: request the listing agent provide image capture dates in writing before any offer, cross-reference street-view tools such as Google Maps for exterior condition, and treat any listing photograph showing pre-2023 appliances or styling in a suburb that has seen heavy renovation activity — Bayswater, Victoria Park, Fremantle — with particular scrutiny. The platforms are catching up. Until they do, the burden of verification sits with the buyer.
