Australia is obviously a developed country, why has it always been called "convex and concave"?

Because the scenery in Australia is different from other developed countries, many people think that developed countries are full of high-rise buildings, with a very fast pace of life and a great degree of urbanization. However, although Australia is rich per capita, most of its territory has not been developed, with many deserts and grasslands and only a few cities. Australians are mostly engaged in farming and agriculture, and they don't look like highly developed countries, so they are ridiculed as Australia, a native of Australia. In fact, these farmers are very rich.

Everyone knows that Australia is a very large country in the world. Although it floats on Oceania, because of its large area, it is not an island country, but a whole continent country. Australia is also a world-famous developed country. Both livability and education are very important in the world, so people from many countries like to immigrate to Australia. Australia, a developed country, has been ridiculed by some people as a native of Australia. Actually, it is not. Australia is called convex and concave because its surface is very rough.

When you arrive in Australia, you will find that you can't see the developed countries at first sight. Generally developed capitalist countries such as Germany, Japan and Britain are very modern, with high degree of urbanization and fast pace of people's life. The technology industry is also quite developed and the price is higher. But living in Australia is a different feeling. This place is very laid-back, and there are not many cities in Australia. Sydney is relatively prosperous. It seems that Australia pays more attention to the environment and original ecology. Here, kangaroos can be seen everywhere, and endless fields can be seen everywhere, unlike developed countries at all.

So many people think that Australia is like a village, which is not advanced or modern at all, but don't forget that those so-called farmers are actually farmers. They are rich. They may keep sheep. Farming is only a sideline, and they are also very idle at home, because social security and medical benefits in Australia are quite perfect, and beggars and poor people rarely appear here. Australia is also rich in educational resources, and many people will study abroad.
