Perth's Property Listings Are Drowning in Duplicate Images — and Agents Are Doing Better Than Most

Perth's real estate portals are removing duplicate and recycled listing images at a faster rate than comparable housing markets in London and Singapore, according to industry monitoring conducted by the Real Estate Institute of Western Australia. The finding comes as the city's rental vacancy rate sits near historic lows and new residents — many arriving under federal immigration programs — are making high-stakes housing decisions based on photographs alone.

The timing matters. Western Australia's population grew by roughly 3.1 per cent in the year to March 2025, according to the Australian Bureau of Statistics, and the pace has not meaningfully slowed since. In that environment, a single misleading image — a bathroom photo lifted from a Subiaco apartment and pasted into a Midland listing, for instance — can push a family to sign a lease for a property they have never physically inspected. Complaints to Consumer Protection WA about misleading rental advertising have risen each quarter since mid-2024, though the agency has not published a final annual tally for 2025-26.

How the Problem Looks Across Global Cities

In London, the property portal Rightmove acknowledged in early 2026 that duplicate image detection had become a significant moderation challenge as agencies consolidated and recycled photography across multiple listings. Singapore's Urban Redevelopment Authority flagged a similar pattern on PropertyGuru in late 2025, linked to a surge in short-stay sub-leasing. Both cities are still largely relying on reactive complaint systems — users flag a problem, a human reviews it days later.

Perth, by contrast, has moved toward automated pre-publication screening on at least one major platform. REIWA's digital compliance team began rolling out image-hash matching software in March 2026, a system that cross-references every uploaded photograph against a database of previously published listing images before the advertisement goes live. The technology is not unique — Airbnb has used similar tools for years — but its adoption in the residential real estate sector here is ahead of where Sydney and Melbourne were at the same stage of their post-pandemic rental crises.

Specific trouble spots have emerged around the Stirling and Cannington corridors, where Metronet construction activity has triggered rapid turnover in rental stock. Property managers along Beaufort Street in Mount Lawley and around the Carousel shopping precinct in Cannington have been among the most frequent subjects of duplicate-image complaints lodged with Consumer Protection WA this year. The agency has the power to issue infringement notices of up to $5,000 per breach under the Australian Consumer Law as applied in Western Australia, though enforcement actions specifically targeting image duplication remain rare.

What Perth Is Getting Right — and Where It Falls Short

The gap between Perth's approach and that of, say, Greater Manchester — where Trading Standards offices handle complaints manually with response times sometimes exceeding three weeks — is measurable. REIWA's system flags a suspected duplicate within minutes of upload, giving the listing agency a chance to correct or replace the image before the advertisement reaches a prospective tenant or buyer.

The weakness is coverage. The automated screening currently applies only to properties listed through REIWA's own portal infrastructure. Private Facebook Marketplace listings, Gumtree advertisements, and smaller boutique platforms operating outside the peak bodies fall through entirely. A two-bedroom unit in Victoria Park can carry a photograph that originally depicted a renovated Fremantle terrace, and no automated system will catch it unless someone complains.

Consumer Protection WA recommends that anyone renting or buying in Perth without an in-person inspection request a timestamped video walkthrough from the managing agent and cross-check property images using reverse image search tools such as Google Lens before signing any agreement. For properties in new Metronet-adjacent suburbs such as Morley or Ellenbrook, where the stock is changing quickly, the agency suggests verifying that the street number visible in exterior shots matches the listed address — a check that catches a surprising number of recycled photographs.

REIWA has indicated it plans to extend the image-hash system to cover property management renewals and re-listings by the end of the 2026 calendar year, which would address one of the most common duplication pathways: agencies re-using three-year-old photographs when a property returns to the market without renovation.
