Melbourne's building sector confronts the duplicate image problem: what officials, experts and key figures are saying

Victoria's planning and construction sectors are grappling with a mounting problem inside their digital archives: duplicate images embedded in development applications, heritage assessments and building documentation are slipping through approval workflows, raising concerns about accuracy, accountability and the integrity of public records.

The issue has sharpened in 2026 as the Allan government presses ahead with its housing density reforms, pushing local councils to process higher volumes of planning applications faster than at any point in the past decade. That acceleration has put pressure on the document management systems underpinning approval decisions, and industry figures say the cracks are showing.

What planning bodies and practitioners are flagging

The Victorian Planning Authority, which coordinates strategic land-use planning across metropolitan Melbourne, has been fielding concerns from councils about inconsistencies in submitted documentation. When duplicate images appear across multiple applications — identical site photographs submitted under different addresses, or recycled elevation renders presented as original assessments — it can distort how a site is evaluated against planning overlays and neighbourhood character guidelines.

At the Moreland practitioner roundtable held in Coburg in May, planning consultants raised specific concerns about image duplication inside ePlanning portal submissions. The portal, administered through the Department of Transport and Planning, accepts digital uploads for development applications across the state. Without automated duplicate-detection built into the intake process, reviewers must catch errors manually — a step that several practitioners described as unreliable under current workloads, though The Daily Melbourne has not independently confirmed official statements to that effect.

The City of Melbourne's own heritage team, which manages documentation for precincts including Carlton, Fitzroy and the Hoddle Grid, has separately acknowledged that its photographic archive — compiled over decades and now running to hundreds of thousands of records — contains known instances of image duplication. How those duplicates affect heritage overlay assessments is an active question for the team, though the council has not published findings on the scale of the problem.

RMIT University's Urban Futures research cluster, based at the Swanston Street campus in the CBD, has been examining document integrity in planning systems as part of broader work on the digitisation of built environment records. Researchers there have pointed to the absence of metadata standards across Victorian council submissions as a structural gap — different councils require different file formats, resolutions and naming conventions, which makes cross-referencing images between applications technically difficult.

The data problem and what comes next

A 2025 audit of development applications lodged with three inner-Melbourne councils — published by the Planning Institute of Australia's Victorian division — found that roughly one in eight submitted image files contained duplicate or near-duplicate visual content when checked against earlier applications from the same applicant or site. The audit covered applications lodged between January and June 2025. The institute stopped short of characterising the duplication as deliberate misrepresentation, noting that workflow errors and reused template documents were more common explanations.

The cost of remediation is not trivial. Planning consultants in Brunswick and Richmond have indicated that cleaning up a single complex application can take several days of staff time, though individual costs vary widely depending on the scope of the project.

The Department of Transport and Planning is understood to be reviewing its ePlanning submission standards, with a focus on metadata requirements and automated file-checking tools. No public consultation date has been announced. The Victorian Building Authority, which oversees building permits separately from planning approvals, has not yet signalled whether it will align any changes with the planning portal reforms.

For practitioners lodging applications now, the practical advice circulating among Melbourne planning firms is straightforward: audit image files before submission, apply consistent naming conventions tied to the property address and date of inspection, and keep original camera metadata intact to assist reviewers. The City of Yarra published updated submission guidance on its website in March covering exactly these points, making it one of the first councils in metropolitan Melbourne to formalise the advice in writing. Other councils are expected to follow, though timelines remain unconfirmed.
