Duplicate Images on Perth's Property Listings: What Happens Next and the Key Decisions Ahead

Property listings across Perth's inner and outer suburbs are increasingly turning up duplicate or mismatched images — photographs recycled from earlier sales cycles, swapped between addresses, or carried over from pre-renovation records — and the agencies responsible for cleaning up those databases are now under mounting pressure to act before the spring selling season kicks off in September.

The problem has sharpened this year because of the scale of WA's housing market churn. Perth recorded its highest volume of residential transactions in more than a decade through the first half of 2026, driven partly by demand from defence-sector workers relocating ahead of AUKUS-related expansions at HMAS Stirling on Garden Island, and partly by interstate migration that has kept vacancy rates across the northern corridor — from Joondalup to Butler — below two per cent. When listings move that fast, image libraries at real estate portals and local government planning databases struggle to keep pace.

Where the Problem Is Landing

The practical consequences are visible in two distinct places. The first is on commercial listing platforms, where sellers in suburbs like Baldivis and Ellenbrook — both of which have seen high-turnover new-build estates — have found photographs of comparable but distinctly different homes attached to their addresses. A four-bedroom house on Neerigen Brook Road in Baldivis appearing with images of a property in a neighbouring stage of the same development is not a hypothetical; agents across Perth's south-east growth corridor have flagged exactly this kind of mix-up to the Real Estate Institute of Western Australia.

The second pressure point is within the City of Perth and surrounding councils, whose online planning and rates portals pull property imagery from state land information systems. The Landgate database, which underpins most official WA property records, undergoes scheduled image refresh cycles, but the interval between a building's physical change and its updated record can stretch to 18 months in high-construction zones. Suburbs around the Bayswater Metronet station — where medium-density development accelerated following the station's opening — have been a particular source of discrepancies, with strata lots sometimes carrying the aerial imagery of the vacant lot that preceded them.

The Decisions That Now Need to Be Made

For sellers, the immediate decision is whether to audit listing images before going to market rather than after. This sounds obvious but adds cost: a professional real estate photographer in Perth charged between $250 and $450 for a standard residential shoot as of mid-2026, and many vendors have historically relied on archived shots from a previous sale. Replacing those images — especially on portals that charge additional fees for re-uploads after an initial listing window — can push pre-sale preparation costs higher at a moment when mortgage pressures are already squeezing discretionary budgets.

For councils and state agencies, the fork in the road is whether to pursue automated detection tools or invest in manual audit cycles. The Department of Planning, Lands and Heritage has been consulting on a broader digital cadastre modernisation program through 2025 and 2026, and duplicate image detection has been identified as a component of that work. The key question is timing: a fully automated matching system capable of cross-referencing Landgate records with third-party listing portals would require interoperability agreements that do not currently exist between state government and private real estate platforms.

Buyers are left navigating this in the meantime. The most direct protection remains requesting a fresh Section 10.7 certificate — or its WA equivalent property disclosure paperwork — and independently verifying that the photographs in any listing correspond to the physical address before making an offer. At current Perth median house prices, which the Real Estate Institute of Western Australia tracked above $800,000 in 2026, the cost of a pre-purchase building inspection remains the most reliable check against image-driven confusion. Title searches through Landgate, available for a nominal fee online, also allow buyers to confirm lot dimensions against what is depicted.

The spring selling season will test whether the platforms and agencies move first, or whether the pressure falls, as it has historically, on individual buyers to catch errors that slipped through institutional systems.
