Duplicate Files Slow Wollongong Council Planning Approvals, Costing Ratepayers

Wollongong City Council's digital document management system is carrying thousands of duplicate image files across its planning, rates, and community services portals, a quiet administrative headache that is now directly slowing development applications at a time when the Illawarra region is under intense pressure to approve new housing and industrial projects.

The problem has come into sharper focus in mid-2026 as councils across New South Wales roll out upgrades to comply with the state government's Digital Information Security Policy, updated in late 2025. For Wollongong, the timing is awkward. The city is simultaneously processing a surge of rezoning applications around the Port Kembla renewable energy zone and managing documentation for BlueScope Steel's green steel transition, two streams of work that depend on clean, retrievable digital records.

What Duplicate Images Actually Do to a Planning Portal

The issue is more mundane than a cyberattack, but the downstream effects are real. When the same site photograph, cadastral map, or heritage overlay scan is uploaded multiple times, often because different staff or external consultants submit the same supporting document through separate logins, the system balloons in size, search results return conflicting file versions, and staff must manually reconcile records before any decision can be signed off.

At Wollongong City Council's Burelli Street headquarters, planning staff are understood to be working through a data audit that began in the first quarter of 2026, though the council has not publicly confirmed a timeline or cost for the remediation work. Similar audits at comparable NSW regional councils have run to tens of thousands of dollars in contractor hours, according to procurement records published by the NSW Government's ICT procurement framework.

For residents lodging a development application, whether for a granny flat in Fairy Meadow or a commercial fitout on Crown Street in the CBD, the practical consequence can be a delay of several additional weeks while staff confirm which version of an uploaded document is the authoritative one. The NSW Planning Portal, through which most Wollongong DAs are now lodged, flags duplicate file names as a validation warning, but does not automatically reject or merge them, leaving the reconciliation work to council officers.

The University of Wollongong's SMART Infrastructure Facility, based on Northfields Avenue, has been involved in separate digital twinning research for the Illawarra region that touches on exactly this kind of data hygiene problem. Researchers there have noted publicly that the integrity of spatial data sets, including imagery, underpins any reliable modelling of infrastructure or land use scenarios. Corrupted or duplicated source files produce unreliable outputs.

What Residents Can Do Right Now

Wollongong's Community Legal Centre on Keira Street has begun advising clients lodging planning documents to keep a local copy of every file they upload, noting the date, file name, and portal reference number at the time of submission. That record becomes critical if a dispute arises over which version of a document was considered in a decision.

The NSW Government's Planning Portal support line, 1300 305 695, can confirm whether a specific DA lodgement has triggered a duplicate file warning, and applicants are entitled to request a written status update within 10 business days under the Government Information (Public Access) Act 2009.

Council is expected to publish an updated Digital Asset Management Policy before the end of the 2026 calendar year, according to its publicly available operational plan. That policy will set out how duplicate records are identified, merged, or deleted, and who holds sign-off authority.

For now, the practical advice for anyone with an active application at Wollongong City Council is straightforward: use consistent, descriptive file names before uploading, avoid resubmitting the same document through multiple accounts, and follow up in writing if a lodgement sits without a completeness check for more than 14 days. In a housing market where Wollongong's median house price sits above $900,000, a preventable administrative delay is not a trivial inconvenience.
