Are Australia and Australia talking about the same place?

Yes, it is the same place, Australia, with a land area of 7,692,024 square kilometers. It is bordered by the Coral Sea and tasman sea in the Pacific Ocean to the east, and the Indian Ocean and its marginal seas to the west, north and south. It is the only country in the world whose territory covers the whole continent, so it is also called "Australia". The word Australia, originally meaning "the continent of the south", comes from the Latin terraaustralis.

Extended data:

The topography of Australia is very distinctive. Eastern mountainous area, central plain and western plateau. The highest mountain in China, Kosi Asco, is 2228 meters above sea level. Near the sea, it is a long and narrow beach with a gentle slope, which slopes gently to the west and gradually becomes a plain. There is the Great Barrier Reef on the northeast coast. Australia has many unique animals, plants and natural landscapes, and is a multicultural immigrant country.
