Brisbane councils and developers scramble to fix duplicate image problem swamping planning portals this week

Brisbane City Council's online development portal flagged more than 340 duplicate image files across active planning applications during the last week of June, triggering a system-wide audit that is still running as of Saturday. The problem — identical image files lodged multiple times under different file names — has slowed assessment queues at a moment when SEQ's construction pipeline can least afford the delay.

The timing matters. South East Queensland is processing a record volume of development applications, driven by interstate migration from New South Wales and Victoria, 2032 Olympics infrastructure commitments, and the State Government's push to accelerate housing supply along the Logan and Ipswich corridors. Any bottleneck in the digital assessment chain adds days to approval timelines, which in a tight construction finance environment can cost applicants real money.

What happened this week

The audit at Brisbane City Council's Development Assessment branch, headquartered at 1 William Street in the CBD, identified the duplicate image clusters concentrated in applications lodged through the PD Online portal between 1 May and 27 June 2026. The files in question are mostly site photographs and elevation renders — large JPEG and TIFF files that consultants inadvertently re-uploaded when the portal timed out during peak periods. Assessors working across the Fortitude Valley Priority Development Area and the Kurilpa Riverfront Renewal precinct in West End reported the greatest concentration of the problem files.

At the state level, the Department of Housing, Local Government, Planning and Public Works confirmed this week that its SARA — State Assessment and Referral Agency — system had also encountered duplicate image flags on 17 referral applications. Planning consultants working on projects in Ipswich's Ripley Valley Priority Development Area said the duplication errors had prompted requests for resubmission on at least two large residential subdivision proposals, pushing expected decision dates from July into August.

The Queensland Government's PD Online platform, which handles the bulk of development applications across the state, has a 50-megabyte single-file upload limit. When connections drop and consultants resubmit, the system currently lacks an automatic deduplication check, meaning identical images sit as separate entries and confuse automated pre-assessment checks. The Department of State Development confirmed it is working with Technology and Digital Solutions — the government's ICT delivery arm — on a patch, though no public release date has been set.

Practical steps for lodging applicants

For the roughly 200 planning and architectural firms operating out of offices along Ann Street and across the Newstead and Fortitude Valley consultant precinct, the immediate workaround is manual. The Development Industry Consultative Group, which meets quarterly with Brisbane City Council officers, circulated a technical note on 2 July advising members to compress image files below 5 megabytes before upload, use sequential file-naming conventions to make duplicates visible at a glance, and to telephone the Council's pre-lodgement team on the dedicated line before resubmitting any application flagged with a portal error message.

The City Council says it has temporarily assigned two additional officers to the document-checking queue to clear the backlog before the end of the financial year close-out period. Applications inside the Gabba Renewal Corridor — where the rebuilt stadium precinct is generating a cluster of ancillary development proposals — have been prioritised for manual review given their time sensitivity ahead of 2032 procurement schedules.

Applicants with live applications affected by duplicate flags should check their PD Online dashboard before 11 July, when the Council expects the first phase of its audit to be complete. Those with referral matters at SARA should contact that agency's lodgement support team directly, as the state and local systems are running separate remediation processes on different timetables. The longer-term fix — an automated deduplication layer built into PD Online — is understood to be part of a broader portal upgrade scoped for delivery before the end of 2026, though no budget figure or contract has been publicly announced.
