This book provides an introductory overview on the "art and science" of predicting bushfire behaviour as well as an historical perspective of fire behaviour research in Australia. It then identifies a total of 22 fire spread models used operationally for wildfire and prescribed burning applications. The models cover fire spread prediction in a wide range of fuel types, including hummock and continuous grasslands, shrublands, dry and wet sclerophyll forests, as well as pine plantations.
