Perth's Property Listings Are Drowning in Duplicate Photos — And the Industry Is Only Just Waking Up

Perth's rental and sales listings have a clutter problem. Across platforms including Realestate.com.au and Domain, duplicate property photographs — the same image appearing two, three, sometimes half a dozen times within a single listing — have become commonplace enough that industry bodies are now treating it as a systemic data quality issue rather than an occasional oversight.

The timing matters. Western Australia's property market is running white-hot. The Real Estate Institute of Western Australia reported in its most recent quarterly data that Perth's median house price crossed $780,000 in early 2026, with rental vacancy rates sitting below one per cent across inner suburbs including Leederville, Mount Lawley and Fremantle. When buyers and renters are making decisions in hours rather than days, a listing padded with repeated images wastes time they simply do not have.

What's Driving the Problem in Perth

The surge in AUKUS-related defence worker relocations to the Stirling Naval Base corridor — particularly in suburbs north of the city such as Stirling and Karrinyup — has pushed listing volumes up sharply since late 2025. More listings, turned around faster, by agencies under staffing pressure, produce more errors. Automated listing software that pulls images from a shared media library can duplicate files if folder structures are disorganised, and few agencies have a dedicated quality-check step before a property goes live.

Metronet's ongoing expansion has compounded the rush. Suburbs along the new Morley-Ellenbrook Line corridor, including Noranda and Bennett Springs, have attracted speculative listings from developers who sometimes submit the same renders or architectural photographs multiple times under slightly different file names — enough to fool basic deduplication filters but obvious to any human scrolling through a gallery.

The Property Council of Australia's WA division has flagged digital listing standards as a priority for its 2026 advocacy agenda, though no binding code yet exists to mandate image deduplication before publication on the major portals.

How Perth Compares to Vancouver, Dublin and Singapore

Perth is not alone, but it is behind the curve. Vancouver's Real Estate Board introduced mandatory image-hash verification for MLS listings in January 2025, requiring each photograph to carry a unique digital fingerprint before a listing is approved for publication. Early results from that rollout showed a reduction in duplicate-image complaints of roughly 60 per cent in the first six months, according to figures the board published in its mid-year review.

Dublin's property portal Daft.ie implemented an AI-assisted deduplication layer in mid-2024 after Irish consumer groups raised concerns about listings being inflated to appear more substantial than the property warranted. Singapore's Urban Redevelopment Authority, which regulates property advertising more directly than any equivalent Australian body, has required unique-image certification for HDB resale listings since 2023.

Perth's closest Australian comparison is probably Brisbane, which faced a similar listing-volume spike ahead of the 2032 Olympic Games infrastructure build. The Real Estate Institute of Queensland publicly called for portal-level deduplication standards in March 2026, but no platform has committed to a firm implementation date.

In WA, the Consumer Protection division of the Department of Energy, Mines, Industry Regulation and Safety has the regulatory authority to address misleading property advertising, but duplicate images occupy a grey zone — technically not false, but arguably deceptive when they make a two-bedroom Northbridge apartment appear to have four separate living areas.

For buyers and renters navigating the market right now, the practical advice from industry observers is blunt: count the windows. If the same sightline appears twice in a gallery, treat the listing as having fewer distinct spaces than advertised, and request a floor plan before inspecting. The Real Estate Institute of WA publishes a buyer's checklist on its website that includes image verification as a recommended step — a small but telling sign that the profession knows the problem is real.

Longer term, the pressure will likely come from the portals themselves. Realestate.com.au has been rolling out AI-driven listing quality scores in selected markets, and WA is on the roadmap. Whether that tool catches duplicates before they reach buyers is the question the industry needs to answer before the next rate cut sends Perth's already stressed market into another gear.
