Final answer:
Australia is located in both the Southern and Eastern Hemispheres, characterized by its opposite seasons to the Northern Hemisphere and its vast, sparsely populated land rich in unique biodiversity.
Step-by-step explanation:
The continent of Australia can be found in both the Southern Hemisphere and the Eastern Hemisphere. As the Tropic of Capricorn runs through the middle of the continent, it clearly lies in the southern part of our Earth's hemispheres.
Not only does its position in the Southern Hemisphere mean that its seasons are opposite to those of the Northern Hemisphere, but it also contributes to the unique climate and biodiversity seen in the landmass.
Furthermore, the Eastern Hemisphere houses Australia, where it is significantly recognized for its tourism and vast but sparsely populated land. Its juxtaposition in these two hemispheres fosters distinct physical geography features such as deserts and savannas, which are prevalent in Australia in comparison to other continents.
