Accumulation Bushfire Extents

[View Map in ArcGIS] OFFICIAL Important: Our technical support team is available to assist you during business hours only. Please keep in mind that we can only address technical difficulties during these hours. When using the product to make decisions, please take this into consideration. Abstract This spatial product shows accumulating 3-hourly snapshots of ‘near real-time’ bushfire and prescribed burn extents for all jurisdictions who have the technical ability or appropriate licence conditions to provide this information into the National Near Real-Time Bushfire Extents product. Currency Date Created: October 2025 Modification Frequency: Every 3 hours Data Extent Coordinate Reference: Geocentric Datum of Australia 1994 (GDA94) Spatial Extent North: -9° South: -44° East: 154° West: 112° Source information This dataset is derived from the National Near Real-Time Bushfire Boundaries product. Sources for the current iteration of this dataset have been confirmed by each jurisdiction through the Emergency Management Spatial Information Network Australia (EMSINA) National and EMSINA Developers networks. This Webservice contains authoritative data sourced from: * Australian Capital Territory - [Emergency Service Agency] (ESA) * New South Wales - [Rural Fire Service] (RFS) * Queensland - [Queensland Fire and Emergency Service] (QFES) * South Australia - [Country Fire Service] (CFS) * Tasmania - [Tasmania Fire Service] (TFS) * Victoria – [Department of Energy, Environment and Climate Action] (DEECA) * Western Australia – [Department of Fire and Emergency Services] (DFES) and [Department of Biodiversity, Conservation and Attractions] (DBCA) This webservice does not contain data from: * Northern Territory – Bushfires NT Known Limitations: * This dataset does not contain information from the Northern Territory government. * This dataset contains a subset of the Queensland bushfire boundary data. The Queensland ‘Operational’ feed that is consumed within this National Database displays the last six (6) months of incident boundaries. In order to make this dataset best represent a ‘near real-time’ or current view of operational bushfire boundaries, Geoscience Australia has filtered the Queensland data to only incorporate the last one (1) week’s data. * Geoscience Australia is aware that duplicate data (features) may appear within this dataset. This duplicate data is commonly represented in the regions around state borders where it is operationally necessary for one jurisdiction to understand cross border situations. Care must be taken when summing the values to obtain a total area burnt. * The data within this aggregated national product is a spatial representation of the input data received from the custodian agencies. Therefore, data quality and data completion will vary. If you wish to assess more information about specific jurisdictional data and/or data feature(s) it is strongly recommended that you contact the appropriate custodian. * The ‘Ignition Date’ field in this dataset exhibits a known error up until 22 January 2026. Care must be taken when values from this field prior to this date. Attribute Accuracy: The accuracy of the data attributes within this webservice is reliant on each jurisdictional source and the information they elect to publish into their Operational/Going Bushfire Boundary webservices. Data Completeness: The completeness of the data within this webservice is reliant on each jurisdictional source and the information they elect to publish into their Operational/Going Bushfire boundary webservices. In the case of Queensland’s data contribution: Please see the ‘Known Limitations’ section for full details. Catalog entry: [National Bushfire Extents - Accumulation] Lineage statement The Near Real-Time Bushfire Boundary dataset and this 3 hourly accumulation bushfire boundary product utilise the same underlying source data. Version 1 (2021/22): A 2021/22 version of the National 3 Hourly Cumulative Bushfire Boundaries dataset was produced by Geoscience Australia. This product was owned and managed by Geoscience Australia, who provided both development and delivery. Work on Version 1 of this dataset began in August 2021 with delivery occurring in September 2021. The dataset was discontinued in May 2022 because of insufficient Government funding to sustain the Project. Version 2 (2023/25): A 2023/25 version of a National Accumulation Bushfire Boundaries dataset was produced by Geoscience Australia under funding from the National Bushfire Intelligence Capability (NBIC) – led by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). NBIC and Geoscience Australia have also partnered with the Emergency Management Spatial Information Network Australia (EMSINA) Group to assist with accessing and delivering this dataset. This dataset is the first time where the jurisdictional attributes are aligned to AFAC’s National Bushfire Schema. Work on Version 2 began in August 2023 and was released in late 2023 under formal access arrangements with the States and Territories. Version 3 (2025): A 2025/26 version of the National Accumulation Bushfire Extents dataset is produced by Geoscience Australia under project funding from the Department of Climate Change, Energy, the Environment and Water, and the National Emergency Management Agency, with contributions to the National Bushfire Intelligence Capability. This version builds on technical improvements to the National Bushfire Extents - Near Real-Time product, and only captures new or changed polygons, rather than capturing all polygons from the Near Real-Time dataset every 3 hours as Version 2 did. Work on Version 3 started in September 2025 and was finalised and released in mid-October 2025. This iteration of the dataset is funded until 30 June 2026. Data dictionary Geoscience Australia has, where possible, attempted to align the data to the National Current Incident Extent Feeds Data Dictionary. However, this has not been possible in all cases. Geoscience Australia has not included attributes added automatically by spatial software processes in the table below. ──────────────┬──────────┬──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Attribute name│Field Type│Description ──────────────┼──────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── fire_id │String │ID attached to fire (e.g. incident ID, Event ID, Burn ID). ──────────────┼──────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── fire_name │String │Incident name (if available). ──────────────┼──────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── fire_type │String │Binary variable to describe whether a fire was a bushfire or prescribed burn. ──────────────┼──────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── ignition_date │Date │The date of the ignition of a fire event.
