Burke fire, 20 August 2023 Roper Gulf, Barkly, Burke
The fire started on 20 August 2023 in Burke, Australia, and satellites saw it burning for 58 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 231,553 hectares from heat detections, spread across 3 municipalities.
This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.
Other fire pages in the same area and on the same dates:
It is the 5th largest in Queensland since 2016 (of 1742 with a page). Number 5 in Australia in 2023, of 1237.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 47 days without rain (1 mm or more) when it started.
This area had burned before
61% of the perimeter overlaps earlier fires recorded since 2016: 4,462 ha in 2016, 97,885 ha in 2017, 26,373 ha in 2018, 2,749 ha in 2019, 8,211 ha in 2020, 5,198 ha in 2021, 10,579 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 141,743 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 0.31 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 2 September 2023 the air beside the fire reached 42 µg/m³ of PM2.5. That day averaged 24: 1.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Burke fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 20 August 2023 to 16 October 2023 (58 days). The perimeter dates it from 22 August 2023 to 13 October 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 231,553 hectares (2,315.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Roper Gulf (125,155 ha, 0.7 %); Barkly (56,855 ha, 0.2 %); Burke (51,408 ha, 1.3 %).
- What was the weather like?
- During the fire the temperature reached 38.2 °C, humidity dropped to 6 % and gusts hit 54 km/h. The fire danger index (FWI) reached 86, class Very extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Australia (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 3 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 22 August 2023 to 13 October 2023. 8,450 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 4.0 International (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
