Australia

is a country, continent and island combined. It is located on the southern hemisphere and is underneath papua New Guinea, Indonesia and East Timor and is west of New Caledonia, New Zealand, Vanuatu, Fiji and other Pacific islands.

About the Country
Majority of Australia is desert. Hot, dry, uninhabitable desert. That's why Australia's population is low.

Australia also has a couple of rainforests, mountains (though they're not that high), a variety of different islands, a fair share of cities and towns, a huge amount of animals, and a lot more stuff.

A lot of it is hot for reasons stated above. In fact, all of Australia has been met with warm-hot climate (if you don't count the mountains, really).

It is also not upside down.

Animals and Plants
There are a lot of spiders, snakes, insects and mutant animals in Australia, so be careful.
