The results of three-body immigration to Australia

This is a very interesting question. In "Three-body", after the three-body man broke through the last line of defense of the earth people, he ordered everyone on the earth to move to Australia within a time limit, otherwise he would be shot!

Why is Australia not Europe, Asia or Africa? There is no explanation in "Three-body". The author Liu must have his own reasons.

If an earth invader wants to find a big prison for mankind, Australia is indeed the best choice. Let's take a look at the picture first:

From the geographical position of the whole world, Australia is roughly in the center. If the residents of Asia, Africa, Europe and America are to be exiled to Australia, then the migration distance of residents from all continents is similar, and the chances of survival are similar. Moreover, there are no other continents in Australia, and it is absolutely impossible to accommodate all mankind, which is convenient for the three people to realize their true intentions-

Before the three-body army reaches the earth, let the "bugs" on the earth kill each other for living space and living resources!

In addition, Australia is an independent continent or an island between the Pacific Ocean and the Indian Ocean. For the three-body invading army, it is perfect to use it as a prison or slaughterhouse for the earth people. If it is well managed, someone will take care of it. If management is not good, it will be gathered and annihilated. Wouldn't it be easier?

There may be another reason, that is, Australia is in a marginal position in the anti-three-body movement of the earth, unlike Asia, Europe and the United States, which are prone to violent anti-three-body movements.

In this way, in Sandy's eyes, Australia is indeed an ideal place to exile people from the earth! what do you think?
