Are Australian mining engineers tired?

Australian mining engineers are not tired. Most mines in Australia are open-pit mines, which are different from those in China. Mining engineers don't need to move ore on their own, so they are not tired. In the early stage, they will make field visits and do some mining and transportation design according to the terrain. Australia's federal territory covers an area of 7.692 million square kilometers, which lies between the South Pacific Ocean and the Indian Ocean and is surrounded by the sea. It is the only country in the world whose territory covers the whole continent, so it is also called "Australia".
