Wildfires are an integral feature of the Australian continent. To estimate the rate of spread of wildfires using computational models it is important to know the kinetic parameters of the materials that constitute the fuel load in forests. These kinetic parameters are utilised in pyrolysis and combustion sub-models of a computational model. In the present work, the kinetics of pyrolysis of timber and litter materials (consisting of bark, twigs, and leaves) from\ Pinus radiata\ and\ Eucalyptus obliqua\ subsp.\ messmate\ forests were estimated under nitrogen. The activation energy for the pyrolysis of timber was found to be independent of conversion, whereas it varied for the litter materials in the range of the pyrolysis temperatures employed. Furthermore, the parameters pertaining to a single equivalent reaction model were also identified. For the samples studied, the most suitable reaction model was identified as the Johnson{\textendash}Mehl{\textendash}Avrami model. The activation energy measurements reported here are consistent with measurements previously reported for other species within the\ Pinus\ and\ Eucalyptus\ genera.
