Fall armyworm (FAW, Spodoptera frugiperda) is an exotic pest that was first detected on the Australian mainland in February 2020. It has since been been detected in the Northern Territory, northern Western Australia and northern New South Wales. Eradication has been determined to be unfeasible and it is now classified as an endemic pest.
