Explanation of an Australian bushfire
An Ausatrailian bushfire is bassically a fire in a forest or a patch of trees. Most Australian bushfires usually burn for a long time and are very hard to put out. this is mostly because most the trees are either dead or dried out. since there is very little water in the tree it meens they can burn very fast and in a big patch of trees this would do alot of damage. an Austalian bushfire is very hot, even hotter than a normal fire because the tree's contain euculiptus oil which has basicly the same effect as petrol.
There are many ways in which a bushfire can start which include dry weather, hot temperatures, flemable plants and trees but in most bushland areas lightning is the cause.
