Perth's Property Listings Swamped by Duplicate Images as Agents Race to Clean Up Digital Portfolios

Perth's real estate sector spent much of this week quietly firefighting a problem that has been building for months: duplicate and mismatched property images flooding listings on major portals, tripping up buyers and exposing agencies to consumer protection risks under Australian Consumer Law. The issue came to a head this week when multiple agencies across the metro area began pulling and reprocessing hundreds of affected listings ahead of the weekend open-home rush.

The timing matters. Perth's property market is running hotter than it has in years, with housing demand driven partly by population growth tied to AUKUS defence workforce migration and a continued influx of resources sector workers. Buyers scrolling realestate.com.au or Domain on a Saturday morning are making decisions faster than ever, and a floor plan from one suburb showing up on a listing in another is no longer just an embarrassing glitch — it can constitute misleading conduct under Section 18 of the Competition and Consumer Act 2010.

Where the Problem Is Hitting Hardest

The duplication issue is concentrated in high-turnover suburbs where listing volumes are highest. Agencies operating out of Subiaco and Victoria Park have reportedly been among those scrambling to reconcile their digital asset libraries this week, according to industry chatter at the Real Estate Institute of Western Australia's West Perth offices on Havelock Street. REIWA, which tracks metro listings data, recorded more than 5,800 active residential listings across Greater Perth as of early July 2026 — a figure that has nearly doubled from the lows of 2022, meaning the sheer volume of images being uploaded weekly has grown proportionally.

The duplication problem has two main sources. The first is legacy: agencies that digitalised paper-era photo archives over the past three years have often ingested the same image set multiple times under different file names. The second is newer — AI-assisted photo enhancement tools, now widely used by agencies and independent photographers operating out of studios in Leederville and Osborne Park, can generate near-identical edited versions of the same shot, which property management software then treats as separate assets and uploads accordingly.

One suburban agency that manages a portfolio of more than 300 properties told colleagues at a mid-week industry briefing in Northbridge that its staff had identified over 140 duplicate image pairs in a single audit conducted between Monday and Wednesday this week. The agency was not named publicly and The Daily Perth was not present at the briefing, but details were relayed by an attendee who declined to be identified. The Daily Perth has not independently verified those specific figures.

What Agencies Are Doing About It

The practical response has varied. Larger franchise groups with internal IT teams have deployed perceptual hashing software — a technique that compares image fingerprints rather than file names — to flag duplicates before they go live. Smaller independent operators in areas like Fremantle and Mount Lawley are largely doing it by hand, with administrative staff cross-checking image libraries against listing records ahead of each upload cycle.

PropTech firms based in the Perth CBD have moved quickly this week. At least two companies operating out of the Brookfield Place precinct on St Georges Terrace have been pitching duplicate-detection modules to agency principals, with one quoting a monthly subscription starting at $299 for portfolios under 100 properties, rising to $899 for larger operators. Those figures come from publicly available pricing pages viewed by The Daily Perth on Friday.

REIWA has not yet issued formal guidance on the issue, but the institute is understood to be monitoring whether existing code-of-conduct provisions adequately cover digital asset management obligations. The Consumer Protection division of WA's Department of Mines, Industry Regulation and Safety, which administers the Real Estate and Business Agents Act 1978, has the authority to investigate complaints about misleading listing content.

Buyers doing their own due diligence should do a reverse image search on any property photos that look familiar — Google Images and TinEye both handle this — before committing to an inspection booking. Agents are also being advised to timestamp their image libraries and keep audit logs, both as a best practice measure and as a defence if a complaint is ever lodged. The weekend listings surge on July 5 will be the first real test of how well this week's clean-up held.
