How does Australia compare with Shanghai (Melbourne)?

See from what angle to understand the first line and the second line.

In terms of national comprehensive strength, Australia is a second-tier country with a population of more than 20 million. The population of a country is not as large as that of Shanghai. It is definitely impossible to become a first-tier country.

However, people's wealth, income level, welfare and environment are among the best in the world, which is higher than that of the largest country in the world.

Australia is not prosperous, although Melbourne was the most prosperous city in the world from the end of 19 to the beginning of the 20th century. However, in the later period, we paid attention to environmental protection, so the construction of high-rise buildings was very weak, and most of the applications for high-rise buildings were rejected. But even so, Melbourne still has the tallest apartment building in the world.

Compared with Shanghai, Melbourne is not as prosperous as Shanghai. In fact, there are no more than five cities in the world that can surpass Shanghai in prosperity, at least compared with the most prosperous areas.

Shanghai's welfare is good now, but it is far from Melbourne, and there is also a gap in the quality of residents, mainly because Shanghai is mixed. The environment is much better than Shanghai. Melbourne has been rated as the most livable city in the world many times, probably the most frequently.
