Hobart council moves to fix ghost images plaguing its digital planning portal this week

The City of Hobart's Development Application Portal has been pulling down and replacing hundreds of duplicate and corrupted property images since Tuesday, after a system audit identified at least 340 files either doubled up or rendering as broken thumbnails across active lodgement records. The fault, traced to a batch-upload script run during a June 18 server migration, affected applications spanning properties from South Hobart to the Salamanca Place heritage precinct.

The timing is awkward. Hobart City Council is under pressure to accelerate planning approvals amid the ongoing debate over the Macquarie Point stadium redevelopment, where cost estimates have already blown past $775 million. Any perception that the council's digital infrastructure is unreliable adds fuel to criticism from opposition councillors that the organisation is not ready for the administrative load the project will bring.

What broke and how it was found

Council's information technology team flagged the problem on the morning of July 1 after a planning officer working on a terrace subdivision in Battery Point noticed the same site photograph appearing across three separate, unrelated applications. A subsequent sweep of the portal, built on the Objective ECM platform, which several Tasmanian councils use, found the duplicated images were concentrated in applications lodged between June 18 and June 27. Roughly 60 of those applications were for properties in the Hobart Local Government Area's heritage overlay zones, meaning the visual documentation carries particular weight in assessment decisions.

The Tasmanian Planning Commission, which handles appeals and state-significant referrals, confirmed on Thursday it had not received any affected files through its own lodgement gateway. The State Government's Department of Natural Resources and Environment Tasmania, which oversees planning policy, said it was monitoring the situation but had not intervened.

Hobart's acting director of city planning sent a notice to registered applicants on July 2 advising them to recheck their submissions. Architects and building certifiers using the portal were told replacements would be processed within five business days, putting the expected clearance date at July 9.

Local practices feel the pinch

Small architectural firms clustered around the CBD on Elizabeth Street have described the week as a scramble. Several practices had active applications sitting in the queue, including two separate projects in the Glebe area and one commercial fitout on Murray Street in the city centre. Without confirmed image integrity, council assessors have been instructed to pause progress on affected files rather than risk approving plans against the wrong photographic record, a conservative call that nonetheless stalls projects already months into the queue.

Statewide, Tasmania's building approval data from the Australian Bureau of Statistics for the March 2026 quarter showed 1,247 residential approvals, down 8.3 per cent on the same period in 2025. Any further administrative delay in the Hobart LGA, which accounts for about a quarter of that state total, compounds pressure on a market already short of housing supply.

The Tasmanian chapter of the Australian Institute of Architects wrote to the council on Thursday requesting a formal update by July 7 and asking whether any applications had been incorrectly assessed during the affected window. Council has not yet responded publicly to that letter.

Residents with applications in progress should log into the Development Application Portal, accessible through the council's main website, and navigate to their lodgement record to check whether a yellow warning banner has appeared against any attached documents. If it has, the applicant or their nominated agent needs to re-upload original image files in JPEG or PDF format before July 9. Anyone uncertain whether their application was caught in the affected batch can call the council's planning counter on Macquarie Street directly, where staff have been rostered for extended hours through the weekend to manage the backlog.
