Background Fire danger rating systems are used daily across Australia to support fire management operations and communications the general public regarding potential danger. Aims In this paper, we introduce Australian Danger Rating System (AFDRS), providing a short historical account of in as well requirements for an improved forecast system. Methods The AFDRS combines nationally consistent, spatially explicit fuel information with weather advanced behaviour models knowledge produce locally relevant ratings potential. Key results A well-defined framework is essential categorising defining based on operational response, impact observable characteristics incidents. modular, supporting continuous incremental improvements allowing upgrades components response new science. Conclusions provides method estimate best available models, leading potentially significant way calculated, interpreted. Implications was implemented 2022, most change forecasting more than 50 years.

Background The Australian Fire Danger Rating System program (AFDRS) has built a new fire danger rating system for Australia. A live trial of the system’s Research Prototype (AFDRSRP), based on behaviour thresholds, was run and evaluated between October 2017 March 2018. Aims Live results are critically analysed, knowledge gaps recommendations future work discussed. Methods bushfire experts assessed wildfires prescribed burns across range vegetation types weather conditions. Forecast ratings calculated using: (1) AFDRSRP; (2) Forest Index (FFDI) Grassland (GFDI) were compared against derived by expert opinion each evaluation (n = 336). Key Overall performance AFDRSRP superior to FFDI/GFDI (56 vs 43% correct), with tendency over-predict rather than under-predict potential. also demonstrated its value assess in fuel not conforming current grassland or forest models; e.g. fuels that grouped use mallee-heath, spinifex shrubland spread models. Conclusions successful, outperforming existing operational system. Implications Identified improvements would further enhance performance, ensuring readiness implementation.

Background Historical records of fire weather phenomena provide valuable insights into spatial and temporal trends which can inform further research are important tools for planning. Aims We outline a 19-year climatology Research Prototype (AFDRSRP), the new Australian Fire Danger Rating System, documenting its characteristics. Methods The analysis utilises Bureau Meteorology’s high-resolution reanalysis suite (BARRA), together with fuel data provided by agencies. examine distribution AFDRSRP. Distributions categorised type, analysing relative variability across time space. Key results validate broad behaviour system insight variation danger throughout Australia, adding detail to understanding timing peak both diurnally annually. Conclusions While AFDRSRP differs from operational in rating categories tuning algorithms, it nonetheless provides useful implementation. Implications These will be essential planning during seasons.
