On 5 December 2022 Coulson aviation sent one of its C130Hs to Busselton Regional Airport as part of a 4-year firefighting contract.
[7] In 2020, a Coulson Lockheed C-130 Hercules aircraft crashed while aerial firefighting for the New South Wales Rural Fire Service during Australia's black summer bushfires, resulting in the deaths of three American firefighters.
[8] The Australian Transport Safety Bureau (ATSB) determined the cause of the collision was likely due to the dangerous weather conditions, low-level wind shear and an increased tailwind, leading to the aircraft stalling while releasing fire retardant foam at a low height and airspeed and colliding with terrain.
In 2023, a Boeing 737-300 aircraft known as Bomber 139 and operated by Coulson Aviation crashed in the Fitzgerald River National Park in the Great Southern Region of Western Australia while fighting multiple fires.
