City of Newcastle has begun a systematic audit of duplicated images across its online asset registers, tourism portals and development application portals after staff identified hundreds of repeated or incorrectly matched photographs embedded in public-facing planning documents. The review, which started in the week of June 30, covers records linked to heritage-listed properties from The Junction through to Islington and archived coastal management imagery from Nobbys Beach and Merewether.
The issue matters now because the NSW Department of Planning's shift toward fully digital development applications — rolled out progressively since the ePlanning portal expansion in late 2024 — has dramatically increased the volume of photographic evidence councils must manage. When the same image appears against multiple properties or when a photo of one street is attached to a DA for a different address, it can delay approvals, create legal exposure and, in the case of heritage listings, generate disputes that end up before the Land and Environment Court.
What Triggered the Audit
The immediate catalyst was a complaint lodged with the City of Newcastle's customer service desk in late June regarding a DA lodged for a terrace on Parry Street, Cooks Hill. According to council's published DA tracking system, the property's supporting photo set contained images that appeared to match a separate property in Hamilton, more than two kilometres away. Council's digital records team flagged the discrepancy and began a broader sweep. The University of Newcastle's Library and Cultural Collections unit, which maintains a separate photographic archive used by local historians and researchers, confirmed this week it had also identified duplicate entries in its Hunter Living Histories database — some dating back to digitisation work carried out under a 2019 State Library of NSW grant program.
Hunter Water and Port of Newcastle both manage large geospatial image libraries for infrastructure monitoring. Neither organisation has publicly confirmed involvement in this week's remediation work, though the broader problem of duplicate asset imagery in utilities and port logistics management is documented in standards published by Standards Australia, including the AS ISO 19650 series covering information management for built assets.
What Councils and Organisations Are Doing About It
City of Newcastle's digital services team is understood to be using image-hashing software to match pixel-level duplicates across its content management system — a standard technique that compares unique numerical fingerprints assigned to each file. Libraries and archives have used similar tools since at least 2015, when the State Library of Victoria published a case study on deduplication across its Trove-linked collections. The process does not delete images automatically; flagged files go to a human reviewer before any record is altered.
Hunter Joint Organisation, which coordinates planning and resource-sharing across the region's nine councils including Cessnock, Maitland and Lake Macquarie, circulated an advisory memo to member councils in the week ending July 4 recommending a common metadata tagging standard to prevent future duplication. The memo referenced the NSW Government's Data and Information Sharing Framework, which took effect in January 2025, as the relevant compliance backdrop.
For small businesses and property owners, the practical implication is straightforward: if you have submitted a development application or heritage enquiry in the past 18 months, it is worth logging into the NSW ePlanning portal and confirming the photographs attached to your application actually show your property. Errors identified by the applicant before a council officer flags them are resolved faster — typically within five business days under City of Newcastle's published service standards — compared with disputes raised after a determination has been issued, which may require a formal Section 8.2 review.
The audit is expected to conclude by late July. City of Newcastle has not indicated whether any DAs have been paused as a result of the discrepancies found so far. Anyone with concerns about their application can contact the council's Planning and Place division through the Hunter Street customer service centre or via the ePlanning portal's secure messaging function.
