Why is there a mountain fire in Australia?

Because Australia's geographical and climatic characteristics are easy to cause mountain fires, although it is surrounded by the sea on all sides, the inland is far from the sea, extremely short of water, and there are no rivers and lakes; Eucalyptus is the main tree species in Australia, accounting for 70% of the forest area. Bark leaves are rich in oil, which gather on the ground after falling off, and are easy to spontaneously ignite when encountering high temperature above 40℃;

The worst mountain fire in Australia's history affected not only itself. Smoke from mountain fires passed through tasman sea and affected New Zealand. On the last day of 20 19, smoke from forest fires in Victoria and New South Wales, Australia drifted eastward, resulting in orange smoke in most parts of South Island, New Zealand.

More than 6,543,800 hectares of land were swallowed up and burned by the fire, which is equivalent to the land area of Austria. The fire has killed 24 people, and nearly 500 million animals (birds, mammals and reptiles) have died in the fire. 1500 houses were destroyed, and thousands of people had to flee and be displaced.
