How Melbourne's Planning System Ended Up Drowning in Duplicate Property Images — and What's Being Done About It

Thousands of Melbourne property listings, heritage citations and urban planning records contain the wrong photographs. Some show buildings that have been demolished. Others pair a Fitzroy terrace with a photograph taken in Footscray. The problem is not new, but the scale of it has only recently become measurable — and the pressure to fix it is intensifying as the state government pushes ahead with housing density reforms that depend on accurate, current visual documentation of existing built stock.

The duplication issue sits at the intersection of several administrative failures that compounded over roughly two decades. Victorian councils adopted different property data systems at different times, with no mandated standard for image metadata or file naming. The result is a patchwork: the City of Melbourne uses one platform, Yarra City Council another, and outer suburban councils a third or fourth variant. When records are merged during planning application assessments or heritage overlay reviews, duplicate images travel with them — sometimes undetected for years.

How the Cracks Formed

The rot set in gradually. During the 2000s, real estate portals including realestate.com.au and Domain began indexing council and land title records to enrich their listings. Those portals applied their own image-processing pipelines on top of whatever councils supplied. A single property sold three times in a decade could accumulate images from three different sources, not always correctly reconciled. By 2015, property technology researchers at RMIT University's Centre for Urban Research had identified image-attribution errors as a systemic data quality problem, though the issue attracted little policy attention at the time.

The pandemic accelerated things in the worst possible way. Between March 2020 and mid-2021, in-person property inspections were restricted across Victoria under public health directions. Agents and council officers relied heavily on archived images, many pulled automatically from legacy databases. New photographs were taken inconsistently. The Victorian Heritage Database, administered by Heritage Victoria and covering more than 2,500 individually listed places across the state, absorbed a fresh round of mismatched imagery during this period as updates were made remotely.

Inner suburbs bore a disproportionate share of the problem. Carlton, Collingwood and Richmond — all subject to active heritage overlays and high listing turnover — saw duplicate image complaints rise noticeably in the years after 2021, according to internal council correspondence later referenced in a City of Yarra planning committee agenda from March 2024. Lygon Street properties and the Hoddle Street corridor were cited specifically in that document as areas where conflicting images had complicated planning assessment timelines.

The Push to Clean Up

The Victorian Government's housing density reform package, announced in stages through 2024 and 2025, has created a practical urgency the earlier data-quality debates never managed to generate. Under the reformed planning framework, councils are required to maintain current photographic records of properties subject to rezoning assessments. That requirement has exposed just how unreliable existing image libraries are.

The Department of Transport and Planning has been working with the Spatial Vision consortium — a Melbourne-based geospatial services company operating out of offices in Carlton — on a deduplication protocol that uses automated image-hash comparison to flag likely duplicates for human review. Spatial Vision has publicly described similar deduplication work in its project portfolio documentation, though the specific Victorian government contract details have not been released.

Property owners and real estate practitioners are not passive bystanders. The Real Estate Institute of Victoria has circulated guidance to members advising agents to audit listing images before submitting to council as part of planning documentation. The advice is particularly relevant for properties in heritage overlays, where an image of the wrong façade can delay an application by weeks while the discrepancy is investigated and corrected.

For anyone navigating a planning application in Melbourne right now, the practical advice from planning lawyers and property consultants is consistent: commission a fresh photographic survey of the property, do not rely on images pulled from previous listings, and cross-check any images attached to heritage citations in the Victorian Heritage Database directly at heritage.vic.gov.au before lodging documents. The cleanup is underway, but it will take time — and in a planning system already under pressure from a housing shortage, every avoidable delay counts.
