Which natural disaster frequently occurs in Australia?

Bushfires are a frequent natural disaster in Australia due to the country's unique climate, vegetation, and geography. The combination of hot, dry summers and periodically dry winters creates optimal conditions for bushfires, especially in regions with abundant flammable vegetation, like eucalyptus forests. These fires can be ignited by natural causes such as lightning strikes or human activities, and they can spread rapidly due to strong winds, making them a significant hazard during the warmer months.

In contrast, while flooding does occur in Australia, it is often seasonal and less predictable than bushfires. Earthquakes do happen but are relatively rare and not as frequent as bushfires. Tornadoes, although they can occur in Australia, are infrequent and typically less devastating compared to the major bushfires that can affect large swaths of land and communities. Thus, bushfires are recognized as a prominent and recurring natural disaster within the Australian landscape.
