An essential feature is dry undergrowth which provides the fuel for the bushfire. Bushfires might start low, but they quickly spread and grow, especially uphill. For every ten degrees of a slope's gradient, the fire speed doubles. The worst bushfires in Australia are crown fires. These are enormously tall fires, which are fuelled by the eucalyptus leaves in the tree tops, generating incredible heat which often causes the tops of the trees to explode.

∙ 12y agoBushfires in Australia are characterised by being most common in dry areas where there is a lot of dry tinder and undergrowth, usually the result of a prolonged drought or heatwave. They can occur in grasslands, but are more common in eucalyptus bushland. Bushfires that burn particularly hot will jump from treetop to treetop. These are known as crown fires, and they are made more intense because the eucalyptus oil in the leaves reaches boiling point and explodes, sending embers in all directions, setting other trees alight.
Australian bushfires are also more common in hills and mountainous areas, as fire moves faster uphill. They are erratic and unpredictable, and can change directiinvat any time.

How common are wildfires in Australia?
Bushfires, as they are properly called in Australia, are very common, particularly during the summer months. Parts of southern Australia, where the summers can be very hot and dry for extended periods of time, are particularly bushfire-prone. Bushfires occur throughout Australia, wherever the vegetation becomes dried out and easily ignited during heatwaves or drought. A common cause of bushfires is when tinder-dry vegetation is struck by lightning.There have been several significant bushfires that have caused great devastation and loss of life in Australia since European settlement. The Black Friday bushfires (1939), Ash Wednesday bushfires (1983), Canberra bushfires (2003) and Black Saturday bushfires (2009) have been among Australia's worst natural disasters.

Why are bushfires more common in southern Australia than northern Australia?
Bushfires are more common in southern Australia because the summer is usually dry as well as hot. In the more northern parts of Australia, the hottest part of the year coincides with rainfall - it is a much more tropical climate.Therefore although northern Australia may be as hot (and usually hotter) than southern Australia, the wetness helps to prevent bushfires.
