Wollongong's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

A growing backlog of duplicated and mismatched property images held across multiple Wollongong City Council databases is forcing a reckoning over how development applications, heritage assessments and public records are managed — and who pays to fix the mess.

The issue has quietly compounded over several years as digital recordkeeping systems were upgraded piecemeal, leaving duplicate photographs and site images scattered across at least three separate platforms used by council planners, the NSW Department of Planning, and heritage advisers operating in suburbs from Figtree to Bulli. With housing supply pressure intensifying across the Illawarra Shoalhaven region, and major industrial decisions looming at Port Kembla, the integrity of visual documentation attached to planning files has moved from an administrative nuisance to a genuine risk.

Why the Timing Matters

The Illawarra is not sitting still. BlueScope Steel's green transition program at Port Kembla — one of the largest industrial transformations the region has attempted — involves a raft of development applications that will reference site imagery spanning more than a decade. If duplicate or outdated images are attached to the wrong file versions, planners assessing environmental impact or heritage constraints could be working from stale visual evidence without realising it.

The same risk applies to residential development. Crown Street in the Wollongong CBD and the Corrimal town centre both have active rezoning proposals under the Wollongong Local Housing Strategy, which targets the delivery of thousands of new dwellings across the local government area by 2029. Duplicate image records attached to heritage-listed properties in those corridors could slow assessments or, worse, result in approvals or refusals made on incorrect visual context.

The University of Wollongong's Innovation Campus at North Wollongong, which straddles the planning boundary between the city centre and the foreshore precinct, has also generated a high volume of development application imagery since 2019. That volume makes the site particularly exposed to duplication errors when records are migrated or audited.

The Decisions That Will Define the Fix

Three choices sit at the centre of what comes next. First, Wollongong City Council must decide whether to undertake a full audit of its image database in-house or engage an external records management contractor — a decision that carries budget implications in a year when the council is managing cost pressures across its capital works program. A full external audit for a local government database of comparable size in regional NSW has historically cost in the range of $80,000 to $150,000 depending on scope, though no council figure has been publicly confirmed for Wollongong's specific situation.

Second, the NSW Department of Planning's ePlanning portal — which draws on council-submitted imagery for state-significant development assessments — needs a protocol that flags duplicate file hashes before documents are formally accepted. That change requires sign-off at the departmental level in Parramatta, not in Wollongong, which limits local control over the timeline.

Third, and most practically for residents and small developers, the question is what happens to applications already in the system that may carry duplicated imagery. Council's development assessment team would need a clear internal directive on whether to proactively review open files or only address duplicates when they are flagged by an applicant or objector. The latter approach is cheaper in the short term but creates legal exposure if a decision is later challenged on the grounds that the assessment relied on incorrect documentation.

Community members with active development applications — particularly those covering heritage-listed properties along the Keira Street corridor or in the Thirroul village centre — should check their submitted documents directly through the NSW Planning Portal and confirm that images attached to their files correspond to the correct address and current site conditions. Applications lodged before July 2024, when council's document management system was last migrated, carry the highest risk of containing duplicated or transposed imagery. The earliest opportunity to formally raise concerns is at the next Wollongong City Council ordinary meeting, scheduled for later this month.
