The central part of Australia is almost barren, but is dotted with mines. There will be a rock fall in one of the mines. The rest of the world will rush to try and rescue the miners; it is going to be a rather serious disaster, which will need worldwide expertise and help. They will need a lot more than the resources and expertise that they have presently. Help will come particularly from America. They will help to rescue the people. This disaster will have some workers underground for a while, but not many lives will be lost.
