Bushfires in Australia are frequent events during the hotter months of the year, due to Australia's mostly hot, dry climate. Each year, such fires impact extensive areas. They can cause property damage and loss of human life. Bushfire can be causes naturalally(electrical stoms) or unnaturally(controoled fires becoming out of control, cicirets.)

Floods in Australia are frequent in the rainy seasons of autumn, winter and spring due to Australia's cold climate during those seasons. They cause millions In property damage every year. they also can cause loss of life

tropical cyclones

a tropical cyclones a rapidly-rowtating storm cycle charecterized by a low-pressure center, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.The main source of energy for tropical cyclones is the warm oceans in the tropical regions. To initiate a tropical cyclone the see-surface temperature generally needs to be above 26.5°C. However, existing cyclones often persist as they move over cooler waters.

Earthquakes

An earthquake is the result of a sudden release of energy in the Earths crust that creates seismic waves. They are one of the worlds largest killers and destroy billions of dollars in property every year. Australias last major earthquake was the banda sea earthquake. Felt in the northern territory, it measured 7.1 on the richtor scale

A storm is any disturbed state of an astronomical body's atmosphere especially affecting its surface, and strongly implying bad weather. It may be marked by strong wind, hail, thunder and lightning (thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc. they are by far the largest natural hazard)

droughts

Drought is an extended period when a region has small
amounts in its water supply whether surface or underground water. A drought can
last for months or years, or may be declared after as few as 15 days.
Generally, this occurs when a region receives consistently below average
precipitation. It can have a substantial impact on the ecosystem and
agriculture of the affected region. Although droughts can persist for several
years, even a short, intense drought can cause significant damage and harm to
the local economy. Prolonged drought has caused cause mass migrations and
humanitarian crises
