Duplicate Image Replacement in Perth's Property Records: The Key Decisions Coming Fast

Western Australia's land title registry is sitting on a problem that has been quietly building for years: thousands of duplicate and mismatched property images embedded in Landgate's digital records, creating discrepancies between what buyers, valuers and planners see online and what exists on the ground. The state government confirmed earlier this year that a formal remediation program was under development, but the path forward — who pays, which technology does the work, and how quickly affected records get corrected — remains unresolved heading into the second half of 2026.

The timing matters because the stakes have rarely been higher. Perth's property market has absorbed wave after wave of demand driven by population growth, resources sector expansion and AUKUS-linked workforce migration to suburbs around Henderson and Rockingham. Accurate imagery tied to title records is not a bureaucratic nicety — it underpins valuations used by lenders, informs planning decisions under the Western Australian Planning Commission, and feeds into strata title disputes that are already clogging the State Administrative Tribunal on Hay Street in the CBD.

What Created the Backlog — and Why It's Getting Worse

The duplication problem traces back to at least two major system migrations at Landgate's Midland headquarters, where aerial and cadastral imagery captured across different survey cycles was ingested without a consistent deduplication protocol. Properties in high-turnover corridors — Ellenbrook, Alkimos and the Forrestfield-Airport Link precinct, where Metronet construction has changed land boundaries repeatedly since 2019 — are disproportionately represented in the error set. Developers lodging subdivision applications in those areas have reported receiving title documentation containing imagery from previous lot configurations, sometimes years out of date.

Real Estate Institute of Western Australia members flagged the issue formally in a submission to Landgate in late 2025, pointing to cases in the City of Swan and along the Mitchell Freeway corridor where aerial photos attached to certificates of title showed structures that had since been demolished or substantially altered. The Property Council of Australia's WA chapter has separately raised concerns about the flow-on effect on Gross Realisable Value assessments used in feasibility modelling for medium-density infill projects, particularly around the Bayswater and Morley activity centres earmarked for rezoning under Perth and Peel @ 3.5 million.

Landgate has not published a public figure for the total number of affected records. Industry sources familiar with the remediation scoping work — speaking in general terms without attribution to specific documents — have described the volume as running into the tens of thousands of titles across the metropolitan region and parts of the Mid West. The agency is understood to be evaluating proposals from at least three vendors for machine-learning-assisted image comparison tools, with a decision on procurement expected before the end of the 2026-27 financial year.

The Decisions That Will Shape the Fix

Three choices now sit in front of the McGowan-era agencies and their successors. First, whether the remediation cost is absorbed into Landgate's existing operating budget — which was allocated a capital spending envelope in the May 2026 state budget — or treated as a discrete project requiring a new appropriation from the Department of Finance. Second, whether affected title holders are proactively notified or required to flag errors themselves, a distinction that carries significant legal risk given the Torrens title system's guarantee of accuracy. Third, whether corrected imagery is sourced from Landgate's own Shared Location Information Platform, known as SLIP, or whether the agency procures a fresh aerial capture program over priority growth corridors.

For homeowners and developers, the practical advice is straightforward: anyone lodging a subdivision, strata plan or development application in a Metronet-adjacent suburb or a rezoning corridor should independently verify that the imagery attached to their title record matches current on-ground conditions before submission. Disputes resolved at the State Administrative Tribunal on Hay Street routinely turn on evidentiary questions about site configuration, and an outdated Landgate image can complicate a case considerably. Conveyancers at settlements across the Perth metropolitan area are already being advised by their professional body to flag discrepancies at the requisition stage rather than allowing them to carry through to settlement. The remediation program, whenever it launches in earnest, will not be retroactive in any meaningful sense — the correction burden, for now, sits with the people who know their property best.
