The wind hazard posed to Australia based on the frequency and intensity of tropical cyclones making landfall around the Australian coastline has been assessed using Tropical Cyclone Hazard Assessment (TCHA). This dataset is a derived product from the original raster layers. We compiled geospatial raster layers for each recurrence interval - i.e. 5 through 10000 years in km/hr unit and classified in 19 classes to better present to a public audience.
