Australia has a unique range of natural hazards that could pose immediate danger to the country. While tropical cyclones can cause intense rain and wind, which leads to flooding and possible costal erosion. Along with the surrounding tectonic plates to the north along the Indo-Australian Plate. Which has been known to pose the threat of earthquakes and tsunamis. I believe the greatest threat to Australia to be wildfires. Also know as, Bushfires and grassfires  they are common throughout Australia. Grassfires are fast moving, passing in five to ten seconds and smoldering for minutes. They have a low to medium intensity and primarily damage crops, livestock and farming infrastructure, such as fences. Bushfires are generally slower moving but have a higher heat output. This means they pass in two to five minutes, but they can smolder for days. Historically, bushfires have caused loss of life and significant damage to property. While naturally occurring bushfires cannot be averte...

Because of Australia's natural location and geography, the whole country is in a potentially at risk for coastal hazards.  Coastal erosion (or shoreline retreat) is the loss of coastal lands due to the net removal of sediments or bedrock from the shoreline. Coastal erosion can be either a: rapid-onset hazard (occurs very quickly, a period of days to weeks) slow-onset hazard (occurring over many years, or decades to centuries).   Coastal erosion is typically driven by the action of waves and currents, but also by mass wasting processes on slopes, and subsidence (particularly on muddy coasts). Significant episodes of coastal erosion are often associated with extreme weather events (coastal storms, surge and flooding) but also from tsunami, both because the waves and currents tend to have greater intensity and because the associated storm surge or tsunami inundation can allow waves and currents to attack landforms which are normally out of their reach.   ...
