Australia has a climate that is mostly hot and dry which are the perfect conditions needed for making a bushfire. Bushfires are frequently occurring events during the hotter months of the year and usually have extremely devastating effects.
Australia is the continent that almost all bushfires occur in. It's geographical location makes the sun very harsh, and the strong winds propel the raging fury. Low relative humidity, high winds and lack of rain all contribute to increased fire danger. Sunshine and high temperatures will quickly deplete all the moisture out of timber and grass which will cause it to burn furiously. Wind is a major factor to Bushfire speed and intensity because fires need oxygen. When the wind speed increases by double the fire's spread rate quadruples. A lack of rainfall (like during a drought) will even make the heaviest of fuels (like large logs) dry out and become perfect for fuelling a fire.
By world standards, Australia has a very low and unreliable rainfall and the whole continent has suffered from droughts many a time. Droughts create a high fire risk, especially if the drought follows a period of good rain that encourages lush, thick growth
But these conditions alone are still not enough to ignite a bushfire. Common causes for bushfires include lightning, arson, accidental ignition from agricultural clearing, campfire, cigarettes and dropped matches, machinery and controlled burn escapes.
